Abstract
The invention provides hitting to plant stake method in three kinds, it is interior implantation prefabricated pile or steel pipe after sinking pipe, can also forms steel tube concrete pile.This method has reached the effect of inner hit method in penetration capacity, pile ending soil bearing capacity etc., has reached the effect of existing plant stake method in pile quality, stake side bearing capacity etc.；The problems such as operation difficulties such as pipe guncreting pile pump concrete are larger, equipment requirement is higher and existing plant stake method bearing capacity of pile tip is relatively low is sunk in solving.
Description
Technical field
The present invention relates to interior hit to plant stake method and its application, belongs to pile foundation construction technical field.
Background technology
Inner hit method, such as interior pile making method for sinking pipe guncreting pile, penetration capacity is strong, high capacity, pile quality are good, but pump
Send that the operation difficulties such as concrete are larger, equipment requirement is higher.
The methods of existing plant stake fado is drilling pile or prefabricated pile is inserted in soil cement, prefabricated pile does not damage, stake
Body quality is good, but is substantially all and belongs to Piles for Friction Piles, and bearing capacity of pile tip is relatively low, does not give full play to the effect of hard supporting course.
The content of the invention
Therefore, the interior tube method that sinks is combined by the present invention with existing plant stake method, it is proposed that is hit in following three kinds and is planted stake method.
Inside hit and plant stake method one：
The existing way follow-up sinking sleeve such as the telescopic pile top of buffering, hammering, vibration or static pressure is hit in 1.1, reaches predetermined and wants
Stop immersed tube after asking；
1.2 hang in prefabricated pile or steel pipe in sleeve pipe；
1.3 into sleeve pipe encapsulating ramming material or loose material, cementitious matter or the loose material filling prefabricated pile or gap of steel pipe and sleeve pipe；
1.4 it is quiet pull out or sleeve pipe of extricating oneself from a predicament and brace oneself up to action, cementitious matter or loose material filling prefabricated pile or steel pipe and the gap in native hole；
1.5 sleeve pipes go out ground, terminate.
Inside hit and plant stake method two：
The existing way follow-up sinking sleeve such as the telescopic pile top of buffering, hammering, vibration or static pressure is hit in 2.1, reaches predetermined and wants
Stop after asking in immersed tube；
The steel pipe suitable for reading for having temporary enclosed is hung in sleeve pipe by 2.2；
2.3 into sleeve pipe encapsulating ramming material or loose material, cementitious matter or loose material filling steel pipe and sleeve pipe gap；
2.4 it is quiet pull out or sleeve pipe of extricating oneself from a predicament and brace oneself up to action, cementitious matter or loose material filling steel pipe and the gap in native hole；
2.5 open temporary enclosed, and concrete is filled into steel pipe, terminate.
Inside hit and plant stake method three：
The existing way follow-up sinking sleeve such as the telescopic pile top of buffering, hammering, vibration or static pressure is hit in 3.1, reaches predetermined and wants
Stop immersed tube after asking；
3.2 hang in open steel pipe suitable for reading in sleeve pipe；
3.3 fill concrete into steel pipe；
3.4 into sleeve pipe encapsulating ramming material or loose material, cementitious matter or loose material filling steel pipe and sleeve pipe gap；
3.5 it is quiet pull out or sleeve pipe of extricating oneself from a predicament and brace oneself up to action, cementitious matter or loose material filling steel pipe and the gap in native hole；
3.6 sleeve pipes go out ground, terminate.
Cementitious matter can use cement mortar or mortar, and loose material can use sand.
To improve filling and other effects, anti-plug can be carried out according to actual conditions.
For method two, incited somebody to action when can hook or block as needed steel pipe with pile top, or prevent from pulling out sleeve pipe with other methods
Steel pipe takes up.
For method three, cementitious matter can pour into sleeve pipe in the lump with the concrete in steel pipe.
Prefabricated pile or the implantation of steel pipe extensible are with long stake of constructing.
Cementitious matter can also be pumped by the Grouting Pipe got off with sleeve pipe.
Can be as needed, seat slurry is first descended after immersed tube, then hang in prefabricated pile or steel pipe.
The method of the existing stake end for improving set tubing bored concrete pile or stake side bearing capacity, the method for reducing soil compaction effect,
It is combined with plant stake method provided by the invention.
It is not very high stake for bearing capacity of pile tip requirement, can be only with other immersed tube classes such as hammering, vibration or static pressure, rotations
The plant stake of stake, hits without interior.
Beneficial effect
Stake in embodiment, pile top diameter 436mm, native hole theoretical diameter 430mm, stake diameter 325mm, the ultimate bearing capacity of stake
6600kN, it is mysterious for existing plant stake method；For existing other bored concrete piles, diameter 730, C30 concrete or
Diameter 630mm, C40 concrete is possible to reach this effect.
For implantation steel pipe, cementitious matter also plays antisepsis.
Method provided by the invention is that the interior pipe that sinks adds implantation prefabricated pile or steel pipe, also concrete can be filled in steel pipe and be formed
Steel tube concrete pile, pile quality is good, no spoir, without mud, more simple to operate than the interior pipe guncreting pile that sinks, to existing stake machine slightly
Rectification can construct；The effect of hard supporting course is given full play to, bearing capacity of pile tip is far above existing plant stake method.
Integrate, interior hit exactly provided by the invention plants stake method, is reached in penetration capacity, pile ending soil bearing capacity etc.
The effect of inner hit method has been arrived, the effect for planting stake method has been reached in pile quality, stake side bearing capacity etc.；Pipe is sunk in solving
The problems such as operation difficulties such as guncreting pile pump concrete are larger, equipment requirement is higher and existing plant stake method bearing capacity of pile tip is relatively low.
Embodiment
The top-down soil layer situation of Site Soil：Miscellaneous fill thick about 1m, the silty of the thick soft modeling-plastic states of about 5m glue
Soil, about 2m thickness is slightly close, in close state fine sand, middle sand, completely decomposed mud stone thick about 1m, intense weathering munstone thick about 3m, below
For middle weathered mudstone.
Designing pile length 15m, the weathered mudstone 3m in, ultimate bearing capacity 6600kN, stake end, stake side ultimate bearing capacity difference
For 5500kN, 1100kN, totally 300 pile.
Stake method two is planted using interior hit.
Sleeve pipe is D426*20 seamless steel pipes, Q345 materials；Pile top is that inner cased type steel-concrete combines pile top, external diameter
D436；Buffer as dry cement；Steel pipe is D325*6 helix tubes, Q345 materials；Cementitious matter is M10 upper flow regime mortars；Coagulation
Soil is C40 self-compactions, slightly expanded concrete.
Using the hollow vibration hammers of 90kW, interior hammer weight 60kN, maximum falls away from 3m.
Construction procedure is as follows：
1. put pile top；
2. vibration sinking tube, immersed tube depth about 9m；
Hit pile top in 3., vibration sinking tube follow-up, last 10 hit pile penetration when being no more than 30mm, stopping immersed tube, and actual stake is long
15.3m；
4. hang in lower mouth closing, the steel pipe suitable for reading for having temporary enclosed；
5. 1m is filled into sleeve pipe3Mortar；
After 6. sleeve pipe of extricating oneself from a predicament and brace oneself up to action goes out ground, remove the next pile of ram machine construction；
7. in three batches, every batch of 100 piles, opening its temporary enclosed, concrete is filled into steel pipe, is terminated.
