Background technique
With extensive use of the seepy material in civil engineering, people gradually propose the design concept of water penetration pile.It should
Novel pile strength of the mixing pile is higher, can form pile body effect, foundation bearing capacity can be improved.Permeable concrete pile has biggish hole
Gap rate, permeability is stronger, is capable of forming good vertical drainage channel, and the ground of embankments construction phase and precompressed phase can be accelerated solid
Rate is tied, settlement after construction is reduced.But water penetration pile can encounter blockage problem in the construction process, lead to the reduction of its water permeability；
During ground consolidation, the removable particle under sufficiently large penetration effect in piping soil can also enter material of body of a pile
Hole results in blockage.
Utility model content
In order to solve the technical problems existing in the prior art, the utility model discloses a kind of anti-clogging strengthening water penetration piles
Permeable geotextiles are carried out intensive treatment, add direction earthwork grille, formed geotextiles cylinder, both can increase pile body by construction method
Forming ability, and the strength of the mixing pile of water penetration pile can be improved.Then it is wrapped up with permeable concrete pile, is formed packed permeable mixed
Solidifying soil stake, both can guarantee good permeability, can reduce soil particle entrance, permeable concrete pile is avoided to block；And geotechnological lattice
The larger tensioning intensity of grid itself, pile body is closely gone along with sb. to guard him, and so that pile body is had biggish intensity and modulus, is improved it and support
The ability of resistance to deformation and destruction.
The specific embodiment that the utility model uses is as follows:
A kind of anti-clogging strengthening water penetration pile, including concrete-pile are equipped with geotextiles cylinder in the outer ring of the concrete-pile,
And the geotextiles cylinder is made of TGXG and permeable geotextiles, positioned at the geotextiles cylinder lower part of pile body bottom and coagulation
It is connected at the top of the pile top of native stake.
Further, it is equipped with connection ring positioned at the side of the geotextiles cylinder of pile body bottom, in the pile top of concrete-pile
Top is equipped with hook, and described is articulated in the connection ring.
Further, the connection ring includes multiple, and multiple connection rings are along geotextiles cylinder lower side annular distribution.

2cm。
Further, the height of the geotextiles cylinder is 0.5-1m higher than concrete-pile, and additional length is bound in stake top
It is fixed.
Further, the geotextiles cylinder includes multiple, and multiple geotextiles cylinders are along on the axis direction of concrete-pile
Lower distribution, and certain length is overlapped between adjacent geotextiles cylinder, and be bonded together.
The construction method of water penetration pile described above is as follows:
Step 1. machine enters scene, and according to design, long, immersed tube soil depth determines frame height and immersed tube length, and carries out group
Dress；
Step 2 places pile top according to design, and pile top is that concrete prefabricated or steel are prefabricated；
Step 3 makes geotextiles cylinder according to stake diameter and length design；
The geotextiles cylinder is divided into permeable geotextiles and direction earthwork grille two parts.Direction earthwork grille is curved into cylinder
Shape, then outside puts on permeable geotextiles, and permeable geotextiles and direction earthwork grille form an entirety, then will cover pipe sleeve
It firmly, can be according to the diameter and length of the long determining geotextiles cylinder of stake diameter and stake；
Geotextiles cylinder is first wrapped in outside of sleeve by step 4, and casing is connect with pile top again, and geotextiles cylinder inlays iron hoop, so
Iron hoop is connected with the hook of pile top top surface again afterwards, keeps geotextiles cylinder not easily to fall off during vibration sinking tube；
Step 5 uses oscillation pipe sinking machine pore-creating；Cloth cylinder is placed on outside pipe, is sling with lifting machine, and cloth cylinder is with pipe in poration process
Sink, pipe starts to carry out water penetration pile perfusion after reaching designed elevation；When filling pervious concrete, tube drawing is to natural ground, then again
Pile sinking is to stake bottom；After filling pervious concrete in casing, certain time is first vibrated, then starts tube drawing again, the tube drawing in vibration,
A certain distance is often pulled out just to stop to pull out vibration certain time；Repeatedly, until pile pipe is all extracted, shape is body formed；
Step 6 closes the geotextiles cylinder iron wire tying for having more pile body, avoids impurity pollution pile body, and clears up stake holes week
It encloses.
Further, the TGXG selects size of mesh opening 80mm × 80mm, and cross rib and longitudinal rib width are 4-5mm, thick
Degree is 2-3mm；To guarantee that geotextiles cylinder is tightly contacted with pile lining with tube wall, geotextiles cylinder diameter is preferably greater than casing 5-8cm, length
Preferably it is longer than designing pile length 0.5-1m, additional length does binding and fixing in stake top.
Since pile body is long, and the structure of geotextiles cylinder is relatively short, therefore can arrange up and down on a pile body more
A geotextiles cylinder, lap width >=200mm between adjacent cloth cylinder, seam is tight, bonding is abundant.
Further, it is switched on before immersed tube, it is necessary to the stake of this is determined according to this position ground elevation and stake end designed elevation
Sharp sinkage.Pile pipe sinking watching and after sinking to projected depth, will check pile pipe verticality, perpendicularity deviation is not in time
Greater than 1%.
The beneficial effects of the utility model are as follows:
Permeable geotextiles have the function of allowing moisture by stopping the losses of sand grains, it is incorporated in water penetration pile
It can be very good to solve blockage problem together.Water penetration pile in the construction process, is easy to happen the problems such as pile body molding is irregular, can
To be reinforced by TGXG to permeable stake body.Permeable geotextiles are subjected to intensive treatment, add direction earthwork grille,
Geotextiles cylinder is formed, not only can increase the forming ability of pile body, but also the strength of the mixing pile of water penetration pile can be improved.Then it is mixed with permeable
Solidifying soil stake package, forms packed permeable concrete pile, both can guarantee good permeability, can reduce soil particle entrance, avoid
Water coagulation soil stake blocking；And the larger tensioning intensity of TGXG itself, pile body is closely gone along with sb. to guard him, make pile body have compared with
Big intensity and modulus improves the ability of its resistance to deformation and destruction.
