PPRk (Crane Work Project)

The installation and safe operation of three tower cranes during the construction of a series of monolithic residential buildings is considered. Due to cramped conditions, the cranes operate with a limited service area.

Stationary tower cranes of the Jaso J110N and Jaso J140N brands erect structures of a 19-story building from elevation 0.000 to elevation. +63.000. The cranes are mounted on foundation supports with a slab elevation of -2.200, with tower anchorage.

The maximum load lifted by cranes at a reach of 2.5-15 m is 5 tons, at a reach of 15-40 m - 2.5 tons.

Tower cranes are used at all stages of construction of the underground and above-ground parts of the building, namely:

• for unloading from vehicles and storing materials and products as they arrive at the construction site
• for supplying packs of reinforcement, reinforced mesh and formwork, as well as for supplying concrete in buckets during the construction of monolithic structures
• for supplying small-piece materials and mortar to the installation horizon
• for supplying and removing construction equipment, equipment, consumables, etc. from the building.

Project scope: Explanatory note A4 - 35 sheets, drawings A1 - 5 sheets

This is an example of a work permit for the excavation of a pit under the protection of a sheet piling fence. Excavation is carried out in 3 stages.

• Stage 1. Work at the level of 135.50÷134.60 is carried out by a Hitachi ZX 200 excavator with a bucket capacity of 0.8 m3 (maximum digging radius - 9.75 m, maximum digging depth - 6.49 m) equipped with a backhoe bucket with loading of soil into dump trucks. With a lag of 4 meters from the operation of the Hitachi ZX 200 excavator, the installation of the strapping belt (1 I-beam N45 B2) is carried out. Installation is carried out using a truck crane according to a separately developed design and maintenance plan.
• Stage 2. Work at level 132.50 is carried out with a Hitachi ZX 200 excavator. At this level, a pit is developed to a design depth of 127.84÷127.84 m, by excavating and moving the soil into a dump truck.
• With a lag of 4 meters from the operation of the ZX 200 excavator, a spacer structure is made, consisting of a strapping belt (2 I-beams N45 B2), spacers made of pipes 426x10mm in axes 1÷10 and struts, as well as pipes 630x12mm in axes 11÷16. Installation is carried out using a truck crane according to a separately developed design and maintenance plan.

Stage 3. Excavation of slopes is carried out by developing and moving soil with a Bobcat S330 excavator into the work area of ​​a Hitachi ZX 225 grab. The grab brings the developed soil to the surface and loads it into a dump truck. The Bobcat S330 excavator is released from the pit upon completion of the work by a truck crane according to a separately developed PPR.

At the last stage, the berm soil is excavated under the installed jibs of the sheet piling fence of the pit using a mini-excavator.

Project for the installation of a water pipeline using the auger method

Laying a water pipeline in a case constructed using a closed auger tunneling method. The excavation of a rectangular working pit and a round receiving shaft is also being considered.

Work on laying pipes using auger tunneling is carried out in several stages:

• 1st stage. Pushing the pilot line, consisting of rods and a pilot head, to the length of the interval from the starting pit to the receiving pit. The exact direction of the route is ensured by a system for monitoring the position of the pilot head, information about the position of which is displayed on the monitor screen suspended in the launch shaft.
• 2nd stage. Punching of casing steel pipes and expander mounted in the starting pit on the last rod of the pilot line within the length of the entire interval between the pits. Pushing out working pipes from the starting pit with simultaneous removal of the squeezed out casing steel pipes in the receiving pit.
• The casing pipes are being pressed with a drilling head at the head of the pipe string, which serves to develop soil in the face; soil is transported from the face to the bucket in the starting pit by a screw conveyor.

3rd stage. Pushing working pipes with a diameter less than or equal to the diameter of the casing pipes, with simultaneous pushing of the casing pipes and screw conveyor links into the receiving pit and their disassembly. When the diameter of the working pipes is less than the diameter of the casing, the construction gap (space) formed between the working pipeline and the inner surface of the excavation must be filled with cement mortar.

Metal structures with cross-sectional dimensions up to 50 mm inclusive are tied into bundles, skeins or bundles of skeins, and over 50 mm - bundled into bundles at the request of the consumer. Bent profiles are tied into bundles.

The cross-section of packs of metal structures, depending on the size and shape of the cross-section, should approach a circle, rectangle or hexagon. By agreement between the manufacturer and the consumer, a different cross-section of the packs is allowed.

When packing metal structures of measured length, the ends of the bundle must be aligned on one side, the protruding ends on the other side must not exceed the maximum length deviations established in the regulatory documentation (ND) for specific types of rental products. By agreement between the manufacturer and the consumer, packaging without aligning the ends is allowed.

During loading and unloading operations, transportation and storage, metal structures must be protected from mechanical damage, for which they should be laid in a stable position on wooden supports and secured (during transportation) with the help of inventory fasteners, such as clamps, clamps, turnstiles, cassettes, etc. .P. Deformed structures must be rejected and replaced with new ones. Do not drop structures from vehicles or drag them on any surface. During loading, slings made of soft material should be used.

The weight of a pack of metal structures, as well as unpackaged rolled products, should not exceed:

- for manual loading and unloading - 80 kg (up to 25 kg per worker);

- with mechanized loading and unloading - up to 1.6 tons.

The passage of vehicles with metal structures, as well as unloading, must be under the strict control of the person responsible for the safe movement of cargo.

Mineral wool boards and sheet metal are also delivered to the construction site using the MMC FUSO manipulator. The elements and materials received at the construction site are placed in the operating area of ​​the installation crane. All materials must be stored in a position appropriate for transport, sorted by size. It is necessary to store materials under a canopy in conditions that prevent their damage.

2.3 Workplace organization

Workplaces must be illuminated in accordance with the requirements of GOST 12.1.046-85, table 1:

Table 1

Lighting standards for workplaces

Concentrations of harmful substances in the air of the working area, as well as noise and vibration levels at workplaces should not exceed established sanitary and hygienic standards.

Microclimate parameters must comply with sanitary rules and standards for hygienic requirements for the microclimate of industrial premises.

Machines and units that create noise during operation should be operated in such a way that sound levels in workplaces, areas and on the construction site do not exceed the permissible values ​​​​specified in sanitary standards.

When operating machines, as well as when organizing workplaces, to eliminate the harmful effects on workers of increased noise levels, the following should be used:

- technical means (reducing machine noise at the source of its formation; the use of technological processes in which sound levels at workplaces do not exceed permissible levels, etc.);

- remote control;

- individual protection means;

- organizational measures (choice of a rational mode of work and rest, reducing the time of exposure to noise factors in the work area, treatment, preventive and other measures).

Areas with sound levels above 80 dBA are indicated with danger signs. Working in these areas without wearing personal hearing protection is not permitted. Workers are not allowed to stay in areas with sound levels above 135 dBA.

Production equipment that generates vibration must meet the requirements of sanitary standards.

2.4 Geodetic work

During the work, geodetic control is carried out. Control consists of checking compliance with basic design requirements. Geodetic control should be carried out directly during the execution of work, after completion of work at the site or site, when accepting work from the performers.

Alignment work begins with reference to the reference geodetic base; during the construction process, the work must ensure that it is carried out in situ from the points of the geodetic alignment base with a given accuracy of axes and marks.

A geodetic alignment basis for construction should be created taking into account:

- design and existing placement of buildings (structures) and utility networks at the construction site;

- ensuring the safety and stability of signs fixing the points of the alignment base;

- geological, temperature, dynamic processes and other influences in the construction area that may have an adverse effect on the quality of construction of the alignment base;

- use of the created geodetic alignment base during the operation of the constructed facility, its expansion and reconstruction.

The accuracy of constructing the construction site alignment network should be taken in accordance with the data given in SNiP 3.01.03-84*.

During the operational period the following is checked:

- safety and immutability of the position of the plan-height base;

- compliance with the setting out of structural elements and alignment axes;

- accuracy of transfer of the main axes of structures;

- correctness of the plan-height position of all structural elements.

During the acceptance control process upon completion of construction, the following is controlled:

- compliance of all geometric parameters of the earthen structure with the requirements of the project and regulatory documents;

- timely and reliable completion of as-built surveys during the construction of column block linings and upon its completion.

The result of this work is as-built geodetic documentation.

Geodetic foundation signs must be supervised during the construction process. Their safety and stability are constantly checked.

All geodetic work during the construction period must be recorded in a work log, which is maintained in parallel with the general work log by the supervisor directly carrying out the construction of this facility.

All executive geodetic documentation is signed by the performing surveyor, chief engineer or person responsible for the work. Acceptance and delivery documentation includes:

- As-built surveys of the mounted piping elements of the column block.

All diagrams indicate the design and actual dimensions or deviations from the design dimensions in height and in plan. The coordinate and elevation system is local. The relative level of 0.000 is taken to be 276.150.

Signed as-built surveys are transferred to the Customer along with acts for hidden work to confirm the scope of work completed.

General management of geodetic control is assigned to the chief engineer.

The results of control observations are recorded in logs.

Newly purchased equipment that requires installation also needs to develop a work plan. This project describes in detail the progress of work, according to which the installation of technological equipment should be carried out.

Requirements for PPR for installation of equipment

The document must be in full compliance with construction standards and regulations. Measures for organizing safety, fire safety, and labor protection must be outlined.

The project for the installation of equipment consists of:

• An explanatory note containing all the details of the requirements for organizing the installation of equipment.
• The calculation and descriptive part, containing unified solutions for installation, assembly methods, describes the necessary types of welding work.

In the lists of installation equipment and fixtures, the planned volumes of activities and the requirements for materials (pipelines, metal structures, etc.) are calculated. The most suitable technologies for specific installation operations are also identified. This also includes a calendar with work schedules.

• A package of drawings and diagrams, including enlarged and technological drawings of the assembly of components and equipment, installation diagrams of lifts, equipment, scaffolding, as well as a diagram for connecting temporary electricity, water, gases and steam. The calculations carried out in the computational and descriptive part determine the required amount of energy resources.

The project for the installation of equipment must be confirmed by all parties who intend to take part in the work.

Why is it necessary to develop a work plan for equipment installation?

To optimize work, reduce its duration and reduce costs, it is advisable to use modern mechanization and technological solutions. For these purposes, any Work Production Project is created.

Installation and construction work must be completed within the agreed time frame. At the same time, it is necessary to ensure fire and environmental safety, labor protection. All this is stipulated in the PPR and is mandatory for execution.

Who should develop the PPR

Development of the Project is the responsibility of the organization installing the equipment:

In the contract construction method, this is the General Contractor.

• When combining the functions of the Contractor and the Customer, this is the Developer.
• To perform specialized or individual types of work, this is a Contractor or Subcontractor.

The chief engineer or the head of the organization performing the installation approves ready-made plans for installation of equipment. Certain types of installation work require the development of separate PPR. They are approved by the contractors and must also be agreed upon with the General Contractor.

If installation work will be carried out on the territory of the enterprise, then the PPR should be agreed upon with the organization operating this territory.

According to the rules, the project for the installation of equipment must be agreed upon, approved and transferred to the construction site two months before the start of the planned installation work.
