Abstract
A foundation pit drainage pipe network belongs to the technical field of foundation pit drainage, wherein drainage pipes are distributed on the ground, and are mutually connected by three-ways, and the end of a whole drainage pipe after the connection by the three way is connected with an elbow with 90 degrees, and the tail end thereof is connected with an elbow with 45 degrees. The utility model substitutes a corrugated pipe used in a traditional drainage system with a U-PVC pipe, which facilitates the whole drainage system to have higher strength, wherein the U-PVC pipe does not directly connect with a sedimentation tank, thereby avoiding the problem of water leakage on the joint of a sedimentation tank and the drainage pipe in the traditional drainage system. The utility model has the advantages of simple structure, convenient construction and easy operation, and the drainage pipes are distributed on the ground, which have convenient maintenance, can be repeatedly used, and greatly save resources.
Description
Technical field
The utility model belongs to the technical field of drainage of foundation pit, is specifically related to a kind of drainage of foundation pit pipe network that the U-PVC pipe carries out draining of laying on the ground.
Background technology
Can underground engineering construction carry out most critical smoothly is dewatering effect, and good dewatering effect is that carrying out smoothly of engineering construction created good condition.Good dewatering effect must have good drainage system to guarantee, if drainage system is not smooth or infiltration, dewatering effect just reduces greatly.
Select following two kinds of drainage systems in the present construction mostly for use: (one) foundation ditch is buried bellows peripherally down underground.This kind way and general buried drain are similar, and leakage area is difficult for checking, and mainly contain 2 reasons and cause and leak: 1. bellows and bellows interface seep water; 2. the ground weight is pressed in and causes it to break on the bellows to leak.For bellows and the infiltration of bellows interface, even whitewash leak stopping after adopting rubber bar or jute packing, effect still is undesirable; Leak for bellows bursts, then can only change the bellows of fracture, cause the full wafer precipitation zone to stop, restricted property on the time, and it is cumbersome to do over again.Also having a unfavorable factor is exactly that deep-well precipitation can be by a large amount of silts on the flexible pipe band, is deposited in the pipe end can not clear up and dwindle the section area that current pass through, and these silts also can directly take outdoor storm sewer to.(2) around foundation ditch, lay bellows on the ground.At foundation ditch spaced around 12m (bellows length is 6m) sedimentation basin (the sedimentation basin planar dimension is 1m * 1m, and the gradient reduces with 2% gradient gradually to outdoor storm sewer, highly is 1m) is set.This kind way ratio is embedded in underground effective, but also has weak point.1. the sedimentation basin wall very easily leaks, and need lay reinforced mesh at the bottom of the pond, prevents the bottom slab crack infiltration; 2., the infiltration of sedimentation basin and bellows interface is difficult to handle; 3. bellows is easily broken, and high-altitude falling object and other people cause bellows bursts easily for factor, influences normal precipitation work.4. the deep-well precipitation leather hose can be placed on the gutter must a plurality of sedimentation basins, and this has just strengthened the possibility of drainage system infiltration.
The utility model content
At problems of the prior art, the purpose of this utility model is to provide a kind of technical scheme of drainage of foundation pit pipe network, and is easy to maintenance, and can repeatedly reuse.
Described drainage of foundation pit pipe network is characterized in that laying on the ground gutter, connects with threeway between the gutter, and the whole piece gutter termination after threeway connects connects 90 ° of elbows, 45 ° of elbows of terminal connection.
Described drainage of foundation pit pipe network, the gradient that it is characterized in that whole piece gutter and ground is 2%.
Described drainage of foundation pit pipe network is characterized in that fixedly installing the pier of laying bricks at the bottom of the pipe of whole piece gutter.
The utility model adopts the U-PVC pipe to substitute the bellows that uses in traditional drainage system, make whole drainage system have higher intensity, U-PVC pipe directly is not connected with sedimentation basin, has avoided the problem that sedimentation basin and drain interface place seep water in traditional drainage system, and the utility model is simple in structure, easy construction, be convenient to operation, and the gutter laying is on the ground, easy to maintenance, can repeatedly reuse, save resource greatly.
Description of drawings
Fig. 1 structural representation of the present utility model.
The specific embodiment
Lay gutter 3 on the ground, it is the U-PVC pipe of 300mm that gutter 3 adopts diameter, connects with threeway 2 between the gutter 3, and the U-PVC threeway is adopted in threeway 2.The U-PVC pipe connects use pvc pipe special glue.One end of threeway 2 upwards is used for placing the deep-well precipitation flexible pipe, and the deep-well precipitation flexible pipe will draw up the water that comes and be discharged in the gutter 3 from foundation ditch.Whole piece gutter termination after threeway 2 connects connects 90 ° of elbows 4, and in order to stop water excessive, end connects 45 ° of elbows 1, and the gradient on whole piece gutter and ground is 2%, makes the water in the gutter flow to the sedimentation basin that sets in advance through 45 ° of elbows 1.Separate with brick wall between sedimentation basin and outdoor storm sewer, prevent that silt from flowing directly into outdoor municipal pipeline.Fixedly install the pier 5 of laying bricks at the bottom of the pipe of whole piece gutter, in order to guarantee its stability.
In concrete work progress, the city planting ductwork drainage outlet should utilize as far as possible on every side, makes the deep-well precipitation drainage system that more delivery port be arranged, and guarantees that draining does not normally delay construction.Gutter adopts the U-PVC pipe, though the U-PVC pipe has certain intensity, but should pay attention to because of falling object from high altitude, tower crane careless manipulation or motor vehicles and machines collision pipe, stops that the people is preloading on pipe.Carry out waterproofing work at the bottom of sedimentation basin wall and the pond, easily cause because of the long-time soft cave-in accident of the ponding soil body if deal with improperly.Also should establish easy and clean ditch water discharge around foundation ditch, surface water flows into foundation ditch when preventing long-time rainfall or heavy rain.
Claims (3)
1. the drainage of foundation pit pipe network is characterized in that laying on the ground gutter (3), connects with threeway (2) between the gutter (3), and the whole piece gutter termination after threeway (2) connects connects 90 ° of elbows (4), the terminal 45 ° of elbows (1) that connect.
2. drainage of foundation pit pipe network as claimed in claim 1, the gradient that it is characterized in that whole piece gutter and ground is 2%.
3. drainage of foundation pit pipe network as claimed in claim 1 is characterized in that fixedly installing the pier of laying bricks (5) at the bottom of the pipe of whole piece gutter.
