Abstract
The utility model discloses a kind of structure for foundation ditch Yield rainfall relation, solve the problem that efficiency of drawing water is low and block, reinforce foundation pit side-wall and the substrate soil body simultaneously.Comprise header, collecting well, open fire ditch and pumping equipment, it is characterized in that, header is made up of steel pipe and dense mesh, header inserts in the foundation pit side-wall soil body and foundation ditch can accelerate the inflow of water to accelerate drainage efficiency and to filter water in the soil body, slip casting can reuse with soil mass consolidation after Yield rainfall relation completes in header.The drainage layer be made up of boulder bed and dense mesh is set in collecting well.The utility model can be used for accelerating foundation ditch Yield rainfall relation efficiency, solves water pump blockage problem, effectively reinforces foundation pit side-wall and the substrate soil body simultaneously.
Description
Technical field
The utility model relates to a kind of structure for foundation ditch Yield rainfall relation.
Background technology
In foundation pit construction process, foundation pit side-wall and substrate have a large amount of underground water and pour in and cause a difficult problem to a great extent, groundwater seepage that foundation ditch may be caused to ftracture to construction in foundation ditch to cave in, and Foundation Pit Pouring causes soil-body landslide at the bottom of foundation ditch to occur piping.In order to ensure the quality of products and engineering carry out smoothly need to adopt the Yield rainfall relation measure of highly effective and safe.The method of tradition foundation ditch Yield rainfall relation many employings open drain collecting well draining, because foundation ditch scope causes greatly Yield rainfall relation efficiency lower, can produce substrate infiltration and foundation pit side-wall soil body penetration, affect foundation pit construction progress and construction safety.
Have various impurity mud because the water in foundation ditch collecting well mixes, occurred by the problem usually having water pump blocking in the process of pumping for water pump, the efficiency having a strong impact on draining also can cause the damage of water pump.
Summary of the invention
The purpose of this utility model is for overcoming above-mentioned the deficiencies in the prior art, there is provided a kind of for the drop and drainage structure in foundation pit construction process, this structure effectively can accelerate the Yield rainfall relation efficiency of foundation ditch, and effectively avoid impurity mud to block water pump, can grouting and reinforcing foundation pit side-wall and the substrate soil body after Yield rainfall relation completes.
In order to solve the problem, technical method of the present utility model is:
For a structure for foundation ditch Yield rainfall relation, solve the problem that efficiency of drawing water is low and block, reinforce foundation pit side-wall and the substrate soil body simultaneously.Comprise header, collecting well, open fire ditch and pumping equipment, it is characterized in that, header is made up of steel pipe and dense mesh, header inserts in the foundation pit side-wall soil body and the substrate soil body can accelerate the inflow of water to accelerate drainage efficiency and to filter water, slip casting can reuse with soil mass consolidation after Yield rainfall relation completes in header.The drainage layer be made up of boulder bed and dense mesh is set in collecting well.
In foundation ditch, confirm the position of each header and make marks.
By hollow steel pipe side face drilling drain hole, hole in soil layer, the steel pipe that will be with dense mesh inserts in soil layer, can filter water body catchmenting fast simultaneously.
In collecting well, arrange drainage layer, drainage layer is made up of dense mesh and the boulder bed be arranged on gauze wire cloth, and boulder bed thickness is 200mm, plays the effect of filtering water body.
Header adopts the steel pipe of wall thickness 10mm, and steel pipe length is determined by foundation ditch concrete condition, and on steel pipe, drain hole diameter is 10mm.
In foundation pit side-wall, header carries out boring layout by the 2% aproll gradient, and in substrate, header horizontal drilling is arranged.
Header arrangement pitch is 10m, and concrete condition is arranged by not affecting construction operation region.
Header length is arranged according to foundation ditch concrete condition.
Pumping system drinking-water pipe is placed in drainage layer bottom.
After Yield rainfall relation completes, injecting treatment is carried out to header.

Marginal data, 1-collecting well, 2-open fire ditch, 3-header, 4-boulder bed, 5-dense mesh, 6-pumping equipment, 7-drain hole, 8-steel pipe.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, the utility model comprises collecting well 1, open fire ditch 2, header 3 and drainage plant 4 and forms.Arrange drainage layer in collecting well 1, drainage layer is made up of boulder bed 4 and dense mesh 5.First determine the position of each header 3 according to working drawing, header 3 is made up of dense mesh 5 and steel pipe 8, and steel pipe 8 is bored drain hole 7, and drain hole 7 diameter is 10mm, and the pipe thickness of steel pipe 8 is 10mm, and steel pipe 8 length is determined according to foundation ditch actual conditions; Carry out boring at foundation pit side-wall and be spaced apart 10m, the aproll gradient is 2%; At the bottom of Foundation Pit, carry out horizontal drilling brill, the spacing of wells is 10m, arranges under concrete condition by not affecting construction operation region; Be trapped among by dense mesh 5 on steel pipe 8 of holing and form header 3, this header structure has the function of catchmenting with filtered water simultaneously.Pumping equipment 6 is placed in boulder bed 4 and dense mesh 5 with upper/lower positions, start pumping equipment 6 and draw water, boulder bed 4 thickness is 200mm.After Yield rainfall relation completes, injecting treatment is carried out to header 3.
The utility model accelerates the efficiency of drawing water by header, solve because foundation ditch Yield rainfall relation efficiency is low and foundation pit side-wall, substrate have the problem descending swelling to enter in large quantities; Header 2 and collecting well 1 can impurity in twice pair of water and mud filter, and avoid drainage plant 4 to block, improve drainage efficiency; After Yield rainfall relation completes, injecting treatment is carried out to header 3 and can carry out second consolidation to foundation pit side-wall and substrate, ensure the safety of foundation pit construction.
