Description
Technical field
The utility model is related to technical field of building construction, and in particular to precast dewatering pile pile in a kind of building foundation pit.
Background technology
In construction, the enlargement of stake diameter becomes trend.Existing large size pile work method has bored concrete pile, prefabricated pile, major diameter
The main stake method processed of three kinds of thin-wall cast-in-situ tubular pile, bored concrete pile stake are the directly perforates on designed stake position, and section is circle,
Steel reinforcement cage is placed after pore-forming in hole, concrete perfusion forms, and due to this pore-creating filling pile, usually there are dregs, mud in hole
The problems such as slurry pollutes and is susceptible to collapse hole；Prefabricated pile is in a variety of materials made of factory or construction site, various forms of
Stake is squeezed into, be pressed into or shaken with sinking apparatus in burying by stake, such as concrete square pile, pile for prestressed pipe, piling bar；Major diameter book wall
For cast-in-situ tubular pile since cylinder end seal is closed, end resistance is big and soil compaction, can not if in pan soil in terms of being generally used for reinforced soft soil ground
Sinking construction.
Prefabricated tubular pile is since the quality of itself is easily guaranteed that, the high capacity of single pile, and is widely used in construction work
Cheng Zhong is often used in Foundation Treatment, in Clayey Soil Ground during construction pile pile, super quiet hole can be generated in ground
Water pressure causes lateral displacement or land upheaval, is likely to result in the engineering accidents such as broken pile, pile body inclining, to engineering construction matter
Amount has a huge impact influence or even causes irretrievable loss.Prefabricated tubular pile composite foundation inter-pile soil undertake load it is larger when
Or foundation soil is when owing consolidation, there are excess pore water pressure between stake, if not setting vertical drainage body between stake, after ground work
The possibility of sedimentation is larger.In order to avoid or reduce above-mentioned adverse effect, it usually needs first vertical drainage body is set in ground,
And take and jump the measures such as pile constructing process, it is relatively complicated to jump pile constructing process so that constructing operation is complicated, construction cost
It is high.
The patent document of Patent No. " CN201520781757.9 " discloses precast dewatering pile pile in a kind of building foundation pit,
The precast dewatering pile pile on engineering pile basis is inserted directly into foundation pit, well casing is installed while forming pipe well, is save in foundation pit
Drilling carries out the construction procedure of well casing installation again, shortens the tube well construction duration.The tube wall of precast dewatering pile pile is equipped with permeable
Hole, precast dewatering pile pile are internally provided with cartridge filter, enter water in cartridge filter by diving pumped by permeable hole.The right prefabricated drop
In use there are still following technical problem, the filter hole of the cartridge filter of the precast dewatering pile pile easily blocks for water pipe stake,
So that its filter effect is deteriorated, seriously affects draining and make the reduction of cartridge filter service life, imitate the draining of precast dewatering pile pile
Rate reduces.
Utility model content
In order to solve the above-mentioned technical problem, the purpose of this utility model is to provide precast dewatering pipe in a kind of building foundation pit
Stake.
Technical solution is used by the utility model：Precast dewatering pile pile in a kind of building foundation pit, including being in hollow
The pile body of shape, the pile top for being arranged on pile body bottom and the cartridge filter being arranged on inside pile body are provided on the pile body multiple
Water hole, multiple filtering through holes are provided on the cartridge filter, and the filtering through hole includes setting successively along pile body to cartridge filter direction
Intake antrum, cushion chamber and the water chamber put, the cushion chamber are in cylindrical, and intake antrum and water chamber are in cone shape and right
Title be arranged on cushion chamber both sides, the axis of the cushion chamber is vertical setting with the axis of intake antrum and water chamber, it is described into
The cross-sectional area of water cavity is gradually reduced along pile body to cartridge filter direction, and the cross-sectional area of the water chamber is along pile body to filtering
Cylinder direction gradually increases, and the first filter screen is provided in the intake antrum, is provided with the second filter screen in water chamber, and described first
The mesh diameter of filter screen is more than the mesh diameter of the second filter screen.
First filter screen and the second filter screen are set in parallel.
First filter screen tilts upward setting along pile body to cartridge filter direction.
Second filter screen tilts upward setting along pile body to cartridge filter direction.
Compared with prior art, the utility model has the advantages that：A kind of building base described in the utility model
Precast dewatering pile pile in hole, good filtration effect are not easy to plug, and drainage efficiency greatly improves, and the first filter screen is larger by particle
Mud and sand filtration, for the second filter screen by the smaller mud of particle and sand filtration, filtering is more abundant, and effectively prevents
Cartridge filter blocks, and improves the service life of cartridge filter；Intake antrum is in cone shape, reduces into water and the first filter screen is rushed
It hits power and ensure that effective water inlet water speed, intake after being buffered in cushion chamber into water chamber, reduce into water to the second mistake
The impact force of strainer so that although the second filter screen mesh diameter is smaller, water inlet is soft, ensure that making for the second filter screen
With the service life, and then improve the service life of precast dewatering pile pile.
