Abstract
The present invention provides the methods that three kinds of immersed tube plant stake, it is first sinking sleeve, it replants into prefabricated pile or steel pipe, concrete can be also filled in steel pipe forms steel tube concrete pile, pile quality is good, no spoir, without mud, thoroughly solves the problems, such as the various aspects such as quality existing for existing driven cast-in-place pile, the effect of hard supporting course is given full play to, bearing capacity of pile tip is far above existing plant stake method.
Description
Technical field
The present invention relates to the methods that immersed tube plants stake, belong to piling Technology field.
Background technology
Existing plant piling method is mostly drilling pile or is inserted into the methods of prefabricated pile in soil cement, and pile is substantially all category
In Piles for Friction Piles, bearing capacity of pile tip is relatively low, can not play the effect of hard supporting course.
The bearing capacity of pile tip of existing driven cast-in-place pile is higher, but undergauge, folder mud, broken pile and other issues are more.
Invention content
To solve the above problems, the present invention provides the methods that following three kinds of immersed tube plant stake.
Method one：
1.1 sinking sleeves stop immersed tube after reaching pre-provisioning request；
1.2 hang in prefabricated pile or steel pipe in casing；
1.3 into casing encapsulating ramming material or loose material, cementitious matter or loose material filling prefabricated pile or steel pipe and casing gap；
1.4 it is quiet pull out or casing of extricating oneself from a predicament and brace oneself up to action, the gap of cementitious matter or loose material filling prefabricated pile or steel pipe and native hole；
1.5 casings go out ground, terminate.
Method two：
2.1 sinking sleeves stop immersed tube after reaching pre-provisioning request；
2.2 hang in the steel pipe suitable for reading for having temporary enclosed in casing；
2.3 into casing encapsulating ramming material or loose material, cementitious matter or loose material filling steel pipe and casing gap；
2.4 it is quiet pull out or casing of extricating oneself from a predicament and brace oneself up to action, the gap of cementitious matter or loose material filling steel pipe and native hole；
2.5 open temporary enclosed, and concrete is filled into steel pipe, terminate.
Method three：
3.1 sinking sleeves stop immersed tube after reaching pre-provisioning request；
3.2 hang in the steel pipe of opening suitable for reading in casing；
3.3 fill concrete into steel pipe；
3.4 into casing encapsulating ramming material or loose material, cementitious matter or loose material filling steel pipe and casing gap；
3.5 it is quiet pull out or casing of extricating oneself from a predicament and brace oneself up to action, the gap of cementitious matter or loose material filling steel pipe and native hole；
3.6 casings go out ground, terminate.
Hammering, vibration, static pressure, rotation or the interior modes sinking sleeve such as hit can be used.
Pile top can be set or not set as needed.
The existing method for improving set tubing pile end or stake side bearing capacity, the method for reducing soil compaction effect,
It can be combined with plant piling method provided by the invention.
Cementitious matter can use materials, the loose materials such as cement mortar or mortar that can use the materials such as sand.
To improve filling effect, anti-plug can be carried out according to actual conditions.
For implantation steel pipe, hook can be set in pile top as needed or hooked with other methods, push down steel pipe, to prevent pulling out
Steel pipe is taken up when casing.
For method three, cementitious matter can be the same as 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 casing.
Can be as needed, seat slurry is first descended after immersed tube, then hang in prefabricated pile or steel pipe.
Advantageous effect
Stake in embodiment, pile top diameter 436mm, native hole theoretical diameter 430mm, stake diameter 325mm, ultimate bearing capacity of pile tip
6600kN is mysterious for existing plant stake method；For existing driven cast-in-place pile, diameter 730, C30 concrete or diameter
630mm, C40 concrete are possible to reach this effect.
For implantation steel pipe, cementitious matter also plays antisepsis.
Method provided by the invention is first sinking sleeve, is replanted into prefabricated pile or steel pipe, and concrete shape can be also filled in steel pipe
At steel tube concrete pile, pile quality is good, no spoir, without mud, thoroughly solves quality etc. existing for existing driven cast-in-place pile
Various aspects problem, has given full play to the effect of hard supporting course, and bearing capacity of pile tip is far above existing plant stake method.
Specific implementation mode
The top-down soil layer situation of Site Soil：The silty of the miscellaneous fill of about 1m thickness, the thick soft modeling-plastic states of about 5m is viscous
Soil, about 2m thickness is slightly close, in close state fine sand, middle sand, the completely decomposed mud stone of about 1m thickness, the intense weathering munstone of about 3m thickness, below
For middle weathered mudstone.
Designing pile length 15m, ultimate bearing capacity 6600kN, stake end, stake side ultimate bearing capacity are respectively 5500kN, 1100kN,
Totally 300 pile.
Stake is planted using method two, vibration interior sinks pipe.
Casing is D426*20 seamless steel pipes, Q345 materials；Pile top is that inner cased type steel-concrete combines pile top, outer diameter
D436；Steel pipe is D325*6 helix tubes, Q345 materials；Cementitious matter is M10 upper flow regime mortars；Concrete is C40 self-compactions, micro- swollen
Swollen concrete.
Using the hollow vibration hammers of 90kW, interior hammer weight 60kN, maximum is fallen away from 3m.
Construction procedure is as follows：
1. putting pile top；
2. vibration sinking tube, immersed tube depth about 9m；
Hit pile top, vibration sinking tube follow-up in 3., last 10 when hitting pile penetration no more than 30mm, stops immersed tube, practical stake is long
15.3m；
4. hanging in the steel pipe suitable for reading for having temporary enclosed；
5. filling 1m into casing3Mortar；
6. after casing of extricating oneself from a predicament and brace oneself up to action goes out ground, removing the lower pile of ram machine construction；
7. in three batches, 100 pile of every batch of opens temporary enclosed, concrete is filled into steel pipe, terminate.
