Abstract
The utility model provides a hidden drainage system in a pipe network of a power station stilling pool. The hidden drainage pipe network is arranged between first-stage concrete and second-stage concrete of the power station stilling pool. The hidden drainage pipe network is composed of a plurality of longitudinal blind ditch pipes and multiple transverse drain pipes. The longitudinal blind ditch pipes are perpendicular to the transverse drain pipes and connected with the transverse drain pipes. Each longitudinal blind ditch pipe is evenly provided with a plurality of vertical drain holes which extend into bed rock. The transverse drain pipes are guided to a foundation drainage gallery and a leaked water collection well for pump drainage. The hidden drainage system in the pipe network of the power station stilling pool well solves the problems encountered when a traditional power station stilling pool drainage scheme is adopted, can also reduce investment and shorten the construction period, and has the advantages of being novel and simple in structure and reliable in use.
Description
technical field
The utility model relates to water conservancy, power technology field, specifically the buried drainage system of a kind of power station absorption basin pipe network.
Background technology
Power station is because the energy major part that high-velocity flow produces all will disappear and stop in the absorption basin of power station, and in pond, change of flow state is larger, the strong turbulent fluctuation of current, and operation condition complexity, requires the stability against floating of each operation condition lower shoe to meet the demands.In recent years, the domestic part power station absorption basin of building all in various degree meet with destruction.The absorption basin of part engineering destroy be because of between layer of concrete in conjunction with bad, drainage system is unobstructed not or because of reasons such as the latent ends of larger pressure fluctuation meter.Think having analyzed after similar engineering absorption basin failure mechanism, in absorption basin structure design, should guarantee the permeability of foundation grouting quality, drain hole, prevent that again the pressure fluctuation meter end of diving from entering plane of weakness.The drainage system of tradition absorption basin is divided into two kinds: one is gallery sealing draining form, and another kind is bright draining form.In gallery sealing draining form base plate, be distributed with the gallery of longitudinal and transverse direction, structural shape complexity; Gallery adopts half embedded to arrange, the thickness of base plate is not fully used, and invests larger.And bright draining form exists pressure fluctuation meter easily along altering under drain hole, cause the problems such as base plate unstability.For this reason, the utility model changes absorption basin foundation drainage into novel block pipe network from the sealing draining of traditional gallery or bright draining form and secretly buries drainage system, at present, there is no application at home on the absorption basin of other power station or hydraulic engineering.
Summary of the invention
The purpose of this utility model is to provide the buried drainage system of a kind of power station absorption basin pipe network, has not only solved well the problem that traditional power station absorption basin drainaging scheme runs into, and can also reduce investment outlay, and the reduction of erection time, uses reliable.
In the absorption basin structure design of power station of the present utility model, should guarantee the permeability of foundation grouting quality, drain hole, prevent that again the latent end of pressure fluctuation meter from entering plane of weakness.Analyzing (initial analysis after similar engineering absorption basin failure mechanism, it is to be combined bad or because of reasons such as the latent ends of larger pressure fluctuation meter with lower-layer concrete interlayer because of anti-impact mill layer that the absorption basin of part engineering destroys, cause absorption basin coal seam floor failure), consider, power station absorption basin drainage system is pressed to pipe network with buried design.
According to stability against floating analysis, base plate thickness is 4m, in the situation that meeting temperature requirements and building ability, need to divide two-layer concrete construction; First floor Concrete Thick is 2.0m, there iing lid heavily under condition, to complete Foundation Consolidation Grouting and curtain grouting, complete after the construction of foundation drain hole, anchor pile, arrange connected in length and breadth drainage pipeline networks, form multiloop connecting pipeline along drain hole, upper strata concrete construction joint, basis infiltration and seam face are leaked and introduced in the collector drain outside absorption basin, the more unified dam collecting well that enters.With respect to traditional gallery sealing pump drainage form and bright draining form, this discharge structure form is referred to as the buried draining form of pipe network.
The technical solution of the utility model is: between power station absorption basin fist stage concrete and second stage concrete, buried drainage pipeline networks is set, formed by several longitudinal blind-ditch pipes and multiple transverse drain, longitudinally blind-ditch pipe and transverse drain are arranged vertically and are interconnected, longitudinally on blind-ditch pipe, some vertical drainage holes of stretching into basement rock are evenly set, transverse drain passes to foundation drainage gallery, and foundation drainage gallery passes to seepage collecting well.Percolating water is caused to seepage collecting well pump drainage.
The advantage of the buried drainage system of power station absorption basin pipe network of the present utility model is as follows:
1. there iing lid heavily under condition, to guarantee foundation grouting quality; 2. drain hole is only punched base plate subfoundation concrete, and pressure fluctuation meter can not be passed to base plate basal plane or concrete layer by drain hole, avoids the destruction of pressure fluctuation meter to base plate basal plane or concrete layer; 3. can drain in time basis infiltration and seam face and leak, reduce substrate uplift pressure.
The utility model has not only solved the problem that traditional power station absorption basin drainaging scheme runs into well, and can also reduce investment outlay, and the reduction of erection time, has novel, simple in structure, the service-strong feature of structure.

The specific embodiment
As shown in Figure 1, between power station absorption basin fist stage concrete 8 and second stage concrete 9, buried drainage pipeline networks is set, formed by several longitudinal (plastics) blind-ditch pipes 1 and multiple transverse drainage (steel) pipe 4, longitudinally (plastics) blind-ditch pipe and transverse drainage (steel) pipe is arranged vertically each other, longitudinally (plastics) blind-ditch pipe connects transverse drainage (steel) pipe, as shown in Figure 2 and Figure 3; Some vertical drainage holes 5 of stretching into basement rock are longitudinally evenly set on (plastics) blind-ditch pipe, and drain hole is only punched base plate lower floor fist stage concrete, as shown in Figure 4; Transverse drainage (steel) pipe causes foundation drainage gallery 6 and enters seepage collecting well pump drainage.In the end of every transverse drainage (steel) pipe, be equipped with by-pass valve control 11, as shown in Figure 5, and for preventing that under extreme case, the water in absorption basin enters in collector drain in a large number, can be by the valve closing of this subregion.
Basis infiltration is entered connected in length and breadth drainage pipeline networks, is formed multiloop connecting pipeline by vertical drainage hole, after collecting, enters collector drain by drainage pipeline networks, then unifies to enter collecting well and carry out pump drainage, to reduce mat foundation uplift pressure.
