Description
Technical field
This utility model belongs to building field, particularly to a kind of Novel underground room drainage and anti-float system.
Background technology
The construction of underground structure relatively deep for buried depth, hydrostatic water table is higher, Anti-floating design is the important component part of structural design.If structural anti-buoyancy is unsatisfactory for requirement, it is possible to cause underground structure floating, bottom slab crack, cause that underground structure in various degree destroys.
The method that current China Anti-floating design mainly adopts " resisting ", namely determines the highest hydrostatic water table, and the difference of dead load and water buoyancy prevents basement structure from floating by adopting the mode of uplift pile, anti-float anchor rod or increase counterweight.This method is primarily present problems with: 1, construction costs is high, serious waste of resources；2, the duration is often longer；3, as measure of anti float lost efficacy, structure self-insurance way is lacked.
Summary of the invention
Goal of the invention: overcome the deficiencies in the prior art, develops a kind of simple in construction, saves resource, shortens the completion time of project, guarantees the Novel underground room drainage and anti-float system of structural safety.
Technical scheme: a kind of Novel underground room drainage and anti-float system, including outer wall of basement, weeper drain, drain pipe, basement bottom board, basement internal drainage ditch, sump, safety valve, water pressure display table, described weeper drain is offered along the outside of described outer wall of basement for one week, and described drain pipe is arranged on the suitable height of described outer wall of basement sidewall；Described sump and basement internal drainage ditch are opened on basement bottom board along the inner side of described outer wall of basement, also set up a number of safety valve, described safety valve is provided with water pressure display table under described basement bottom board.
Described drain pipe position on described outer wall of basement sidewall is lower than the balance water level of basement, and under described balance water level base area, cell structure is determined from re-computation, and when the water level of subsoil water is lower than described balance water level, basement structure is conducted oneself with dignity more than water buoyancy；
One end of described drain pipe is connected with described weeper drain, and the other end leads to basement indoor, is additionally provided with and is opened to the check valve that basement is indoor inside it；When the water level of subsoil water reaches or is higher than the height of described drain pipe, subsoil water flows into drain pipe by described weeper drain, flow to described sump by check valve；
Described safety valve is made up of check valve and pressure transducer, certain water pressure can be born, can manually can also be automatic, after the pressure of external water exceedes certain numerical value, safety valve is opened, subsoil water under basement bottom board is flowed in basement by check valve, it is ensured that basement structure will not destroy because of water buoyancy；Even if the draining impeded drainage at side wall place, outdoor subsoil water cannot be discharged to indoor in time, groundwater level is it would be possible to be increased to more than balance water level, and basement structure just has the risk of floating, but now safety valve is opened, basement is intake, while basement structure deadweight increases, outdoor groundwater level also can decline, and structure reaches balance again, so that it is guaranteed that basement will not float causes structural deterioration, play the effect in two defence lines, road；
Described water pressure display table can launching stress size variation corresponsively in good time, there is supervisory function bit, provide data support for later stage monitoring operation, also have certain scientific research value simultaneously；
The hydrops that basement is indoor can be pooled to sump by described basement internal drainage ditch；
Being provided with pumping equipment bottom described sump, the water of its extraction passes through cross current city planting ductwork；
The power of the size of described sump, quantity and pumping equipment, according to local hydrological data designing and calculating, and with due regard to partial water air pump inoperative time surplus capacity；
Described pumping equipment is generally water pump.
The beneficial effects of the utility model: this utility model saves uplift pile, anti-float anchor rod or counterweight, simple in construction, saves resource, and drain pipe is arranged on below balance water level appropriate location, both ensure that the effect of anti-floating, and do not allowed again the operation cost in later stage too high；It is arranged below safety valve at basement bottom board simultaneously, plays the effect in two defence lines, road, it is ensured that basement structure does not destroy because of water buoyancy.
