GESN 81-02-36-2001 Part 36. Earthen structures of hydraulic structures

State estimate standards State element estimate standards for construction and special construction work (hereinafter - GESN) are intended to determine the need for resources (labor costs of construction workers, machinists, operating time of construction machines and mechanisms, material resources) when performing construction and special construction work and for drawing up, on their basis, estimates (estimates) for the production of the specified work using resource and resource-index methods.

GESN are the initial standards for the development of other estimate standards: unit prices at the federal, territorial and sectoral levels, individual and consolidated estimate standards.

Operation of the pond and dams includes activities for the supervision and maintenance of the dam and spillway structures, their repair and activities for the improvement of the pond area.

The main types of damage are water overflow over the dam crest; water filtration through a dam; destruction of a dam by a breakwater; damage to drainage structures.

Overflow of water over the crest is observed during very large floods or due to the unpreparedness of the spillway structures to handle the flood. To prevent water overflow, spillway structures must be cleared of snow, ice, and debris in the spring before the flood. In case of large floods, when the spillway structures do not have time to discharge water, in order to eliminate the overflow of water, it is necessary to build a temporary spillway channel with water drainage into the beam below the dam.

Cracks often form in new dams before the soil has completely settled due to freezing in the upper layers and continued settlement of the lower layers, leading to the formation of voids. If a transverse crack forms in the dam, you need to dig a trench 1.5-2.0 m deep 0.5 m below the depth of the crack. For a longitudinal crack, a trench is dug along the crack along its entire length. The crack is filled with the same soil from which the dam is made, in layers of 1 5-20 cm with careful compaction.

Filtration of water through a dam can occur if design or construction rules are violated. To eliminate filtration, it is necessary to increase the base of the dam by widening it on the side of the dry slope or to arrange drainage. If the water filtering through the drainage device is clean, this indicates that the dam is in good condition.

The destruction of the dam by a breakwater is eliminated by securing the wet slope with a stone blind area, concrete slabs, or throwing stones over squares made from willow stakes.

Spillways should be constantly cleared of debris, and in the spring of snow and ice. The most common types of damage to spillway structures is the formation of failures along their walls due to water filtration. Dips behind the walls of culverts should be promptly filled with soil.

In order to avoid the erosion of dams, it is necessary to organize observation and concentrate the necessary materials and mechanisms at the time of flood or flood.

The system of operational measures includes landscaping the area around the pond, restoring damaged turf, and creating tree and shrub plantings (the range of species is selected depending on soil and climatic conditions). On the banks of the reservoir along the water's edge, especially in places where the shore is destroyed by a breakwater, it is advisable to plant shrubby willows. When using a pond to extinguish fires, access roads and platforms are built at the water intake points

Periodically it is necessary to clean the pond from herbaceous aquatic vegetation. Small ponds are cleaned by hand; large ponds are cleaned using special mowers and dredgers. After 20-30 years, having completely freed the pond from water, it is cleaned of vegetation, debris and silt. Water is drained through a drain.

Ministry of Forestry of Russia

Forestry Department_

A dam is a hydraulic structure erected to fence artificially created reservoirs and watercourses, raise the bank of a natural watercourse, change the direction of flow and protect the area from flooding.

Five main requirements for dams:

Stability and strength when exposed to forces and loads in various combinations.
Fatigue strength of the structure.
Wear resistance.
Biostability of the materials making up the dam.
Survivability, in other words, is the ability of a dam to perform its functions in extreme conditions.

Unlike industrial and civil structures, hydraulic structures during operation are exposed to various factors related to water - mechanical, physico-chemical, biological. The more thoroughly the survey work is carried out, the more accurate the designers’ calculations will be.

What types of surveys and studies need to be carried out before the start of design work:

topographic survey;
geological research (soil study);
hydrogeological (determining the depth and flow of aquifers, water flow regime in a given area);
construction and production (obtaining information about the transport accessibility of the facility, road conditions, power sources, etc.)

After conducting surveys, during which data will be obtained on the terrain, its geological structure, groundwater levels and water flow conditions, a multi-stage design process begins. It includes preliminary, working and control stages.

What tasks are set for designers?

At preparation of the dam project Region specialists consistently solve the following problems:

establishing the type and size of the structure, taking into account the expected water regime of the facility;
selection of building materials, equipment, technological methods of construction;
production of dam diagrams and drawings, performing calculations;
determination of economic indicators;
establishing the degree of reliability of hydraulic structures necessary to ensure the safety of the population and the natural environment;
compiling a list of design and technological solutions to prevent the development of emergency situations and dangerous damage.

Dam project price

The initial cost of estimate and design documentation is determined on the basis of the regulatory pricing framework. Basic prices are multiplied by a coefficient that takes into account the current market situation. The individual characteristics of each project are clarified during a constructive conversation with the client. Our company assumes warranty obligations and bears financial responsibility for failure to meet deadlines.

The main difficulties and mistakes when designing yourself (with your own hands)		Solutions LLC "Region"
	Lack of an agreed upon design of the Sanitary Protection Zone (SPZ)		We will analyze the current situation and prepare Terms of Reference for the SPZ project. If necessary, we will carry out the design of the sanitary protection zone and coordinate it.
	Lack of metering devices and objective (calculated) data on the required productivity.		We will collect all the necessary data, carry out calculations and present it to the customer for consideration. If necessary, we will carry out temporary installation of metering devices.
	Lack of title documents for land.		We will assist in the preparation of documentation and, if necessary, include it in the design specifications.
	Inaccuracies in the preparation of the Technical Specifications: all necessary research was not taken into account, the above documents were not taken into account.		We will analyze the current situation and prepare the correct technical specifications.
	The price justification was not carried out correctly, based on commercial proposals from non-specialized organizations, without taking into account compliance with the requirements of technical specifications, the need to inspect buildings and structures, etc.		We will prepare an estimate for design and survey work and inspection, according to reference price guides.
	Inspection, surveys, design are carried out by different companies - this causes delays and the appearance of additional work.

The cost of constructing a dam, drainage structure, irrigation network and sprinklers is determined according to local estimates 1, 2 (Tables 6 - 7) and a consolidated cost sheet (Table 8).

1. The volume of cutting of plant soil from the base of the dam is determined by the formula:

Vdis.pl. = F0*hrast,

where: F0 - dam base area, m2;

hrast.s. - cutting thickness of plant soil is 0.3 m.

F0=*=6922.9 m2;

Vdis.pl=6922.9*0.3=2076.87 m3

2. The volume of cutting of plant soil from the surface of the quarry is determined by the formula:

V rast.k. = Fkar. hrast.k.,

where: Fkar - quarry area in plan, m2;

hrast.k. - cutting thickness of plant soil is 0.5 m.

where: Vkar is equal to the volume of the body of the dam under construction, m3;

hkar - depth of quarry development, 8...10 m.

Hence Fkar==8423.65 m2;

Vdis.k=8423.65*0.5=4211.83 m3.

3. The volume of cutting of plant soil from the surface of the discharge structure according to the formula:

Vsol.s. = La*hrast.с *(в + m*h),

where: La = length of the spillway channel, m;

в - width of the channel along the bottom, m;
