Description

A kind of prefabricated tubular pile as well-points dewatering
Technical field
The utility model is related to a kind of industry and residential construction area, more particularly to a kind of prefabricated pipe as well-points dewatering Stake.
Background technology
In the engineering constructions such as basement, deep foundation are carried out, if it is soil that earth's surface is husky or earth's surface upper strata, lower floor is When sand etc., might have substantial amounts of underground water gushes out, and causes landslide, cannot finally construct, and at this moment needs dewatering construction. Traditional Application of light well point precipitation has the following disadvantages:1st, construction manipulation process is complicated, and well-point arrangement will be according to foundation ditch flat shape Arranged with size etc., and the buried depth of foundation ditch is had to enter into water-bearing layer, and scene increases substantial amounts of production work;2nd, it is traditional Well-points dewatering needs to set substantial amounts of well point around foundation ditch, arranges large number of drainage pipeline;3rd, the arrangement of well point is by existing Field construction factor is larger.
Utility model content
The purpose of this utility model be to provide for a kind of economy and constructing operation performance it is all good as well-points dewatering Prefabricated tubular pile.
To achieve these goals, it is the utility model proposes a kind of prefabricated tubular pile as well-points dewatering including prefabricated mixed Solidifying soil pile tube and drain pipeline structure system;The prefabricated concrete pipe pile is cavity structure, and the prefabricated concrete pipe pile Two ends be respectively openend and sealing end;The side wall of the prefabricated concrete pipe pile is provided with several permeable holes, described Filtrable water permeable device is provided with water hole;The drain pipeline structure system is provided with multiple pumping conduits, the pumping conduit Free end inserted from the openend of the prefabricated concrete pipe pile.
Further, in the described prefabricated tubular pile as well-points dewatering, the sealing end of the prefabricated concrete pipe pile It is pyramidal structure.
Further, in the described prefabricated tubular pile as well-points dewatering, the permeable hole is along the precast concrete The horizontal direction of pile tube side wall is uniformly distributed, and vertical direction along side wall is evenly arranged at a certain distance.
Compared with prior art, the beneficial effects of the utility model are mainly reflected in:
1. convenience:Plant equipment required for construction is simple, and can construct part pile foundation in advance, be next step girder system, Pier stud construction provides the scope of operation;
2nd, implementation:By the use of adjacent stake holes as well-points dewatering well, prefabricated pile inner chamber forms natural well point, it can be ensured that well The construction quality of point;
3. economy:By the use of adjacent stake holes as well-points dewatering well, eliminate that original scene was substantial amounts of to punching, arrange derrick It is substantial amounts of to have saved construction cost and human cost Deng work;
4. security:By the use of adjacent stake holes as natural well-points dewatering well, it is to avoid it is live it is substantial amounts of punching, wellhole punching The dangerous construction operation such as shaping is hit, the security and reasonability of Contraction in Site is substantially increased.
Brief description of the drawings
Fig. 1 is the structural representation of the prefabricated tubular pile as well-points dewatering of the present utility model.
Specific embodiment
As shown in figure 1, the utility model proposes a kind of prefabricated tubular pile as well-points dewatering, including precast concrete pipe Stake 1 and drain pipeline structure system 2;The prefabricated concrete pipe pile 1 is cavity structure, and the prefabricated concrete pipe pile 1 Two ends are respectively openend 11 and sealing end 12;The side wall of the prefabricated concrete pipe pile 1 is provided with several permeable holes 3, institute State in permeable hole 3 and be provided with filtrable water permeable device, can effectively prevent other impurity such as silt into prefabricated concrete pipe pile 1 Inner chamber;The drain pipeline structure system 2 is provided with multiple pumping conduits 21, and the free end of the pumping conduit 21 is from described prefabricated The openend 11 of concrete tubular pile 1 is inserted, and the pumping conduit 21 can freely stretch into precast concrete pipe according to actual requirement 1 inner chamber of stake.
In the utility model, its preferred scheme is:The sealing end 12 of the prefabricated concrete pipe pile 1 is pyramidal structure, Enter underground beneficial to prefabricated concrete pipe pile 1.The permeable hole 3 is equal along the horizontal direction of the side wall of the prefabricated concrete pipe pile 1 Even distribution, and vertical direction along side wall is evenly arranged at a certain distance, rationally can effectively carry out high-efficient filter water conservancy project work.
Prefabricated concrete pipe pile 1 is pressed into design and specifies soil layer by pile driving equipment, and underground water is by prefabricated in each soil layer The permeable hole 3 with pervious function of the side wall of concrete tubular pile 1 is penetrated into pile tube, drawing water on the inside of prefabricated concrete pipe pile 1 Pipeline 21 will pour in the water to pile tube and discharges by pumping equipment, and drain pipeline structure system 2 can be easy to multiple pumping conduits 21 carry out drainage works simultaneously, so that this region part level of ground water reduction.
To sum up, in the present embodiment, a kind of prefabricated tubular pile as well-points dewatering of proposition, it has advantages below:
1. convenience:Plant equipment required for construction is simple, and can construct part pile foundation in advance, be next step girder system, Pier stud construction provides the scope of operation;
2nd, implementation:By the use of adjacent stake holes as well-points dewatering well, prefabricated pile inner chamber forms natural well point, it can be ensured that well The construction quality of point;
3. economy:By the use of adjacent stake holes as well-points dewatering well, eliminate that original scene was substantial amounts of to punching, arrange derrick It is substantial amounts of to have saved construction cost and human cost Deng work;
4. security:By the use of adjacent stake holes as natural well-points dewatering well, it is to avoid it is live it is substantial amounts of punching, wellhole punching The dangerous construction operation such as shaping is hit, the security and reasonability of Contraction in Site is substantially increased.
