Abstract
The invention discloses a method for quickly extracting a pile under a lower clearance condition, and the method can be used for quickly extracting the pile under the low clearance condition. The method comprises the following steps: screwing in a steel sleeve by use of low-clearance pile extracting equipment to realize pile-soil separation; integrally ascending the whole pile and then cutting off the redundant part on the upper part of the pile body, backfilling a pile hole and tamping the pile hole until designed elevation; and finally, extracting the steel sleeve. The pile extracting process adopts steel sleeve screwing-in to realize pile-soil separation, so that the pile extracting construction has small influence on the surrounding environment; and a barrier pile is lifted outside of a tunnel pass-through range to cut off the redundant part on the upper part, so that the whole pile is prevented from being pulled out, and the construction efficiency is greatly improved. The method also can complete construction in case of limited clearance height, so that the extracting efficiency of the barrier pile within the tunnel pass-through range is greatly improved.
Description
Technical field
The invention belongs to construction engineering technical field, the method for quick pile pulling under being specifically related to a kind of low-headroom condition.
Background technology
Usually because the construction of follow-up building do not considered by the structure of first constructing in construction work, the obstruction run in subsequent construction also gets more and more, and the bored pile especially pulling out existing structure thing is very common.In the work progress of subway and municipal tunnel, shield machine often needs the pile foundation group passed through below existing building or bridge, and these obstacle piles add the difficulty of construction of shield driving, therefore the pile body within the scope of Tunnel Passing must be removed.This type of construction of removing obstacles often need low in headway, construction period is short, carry out under environmental protection requirement high condition, and traditional pile pulling technique because efficiency of construction is low, ambient influnence large, the limitation such as not thorough of removing obstacles cannot meet the demand.
Summary of the invention
Because the above-mentioned defect of prior art, the method of quick pile pulling under the invention provides a kind of low-headroom condition, quick pile pulling can be carried out under low-headroom condition, first use low clearance pile pulling device to be screwed in by steel sleeve and realize the separation of stake soil, the redundance on cutting amputation pile body top after more whole stake entirety being raised, backfill stake holes and tamping to design elevation, finally pull out steel sleeve, the method when headway first, also can complete construction, make the obstacle pile within the scope of Tunnel Passing pull out operating efficiency and greatly improve.
For achieving the above object, the method of quick pile pulling under the invention provides a kind of low-headroom condition, first use low clearance full circle swinging jacketing machine to be screwed in by steel sleeve and realize the separation of stake soil, the redundance on cutting amputation pile body top after more whole stake entirety being raised, backfill stake holes and tamping to design elevation, finally pull out steel sleeve.
A method for quick pile pulling under low-headroom condition, concrete steps comprise:
(1) excavate pile crown, the earth by whole stake top is removed, and carries out preparation of construction work, comprises diameter, the degree of depth, the spacing between stake and stake of determining whole stake;
(2) low clearance pile pulling device, the low clearance pile pulling device of employing is low clearance full circle swinging jacketing machine;
(3) steel sleeve is sunk in rotation, and low clearance full circle swinging jacketing machine blocks steel sleeve, is rotated by steel sleeve and is drowned into whole stake pile body bottom 1-2m, realize whole stake and be separated with surrounding soil;
(4) low clearance full circle swinging jacketing machine transfers wire rope to locking bottom whole stake;
(5), after the debugging of low clearance full circle swinging jacketing machine terminates, started to pull out, risen to design elevation by the bottom of whole stake stake, design elevation should exceed Tunnel Passing scope;
(6) use cutting equipment by whole stake pile body top redundance cutting amputation;
(7) back-filling in layers stake holes tamping are to design elevation, and design elevation exceeds Tunnel Passing scope;
(8) finally start low clearance full circle swinging jacketing machine, pull out steel sleeve, construction completes.
Preferably, low clearance full circle swinging jacketing machine blocks steel sleeve in described step (3), steel sleeve is rotated to be drowned in the process of whole stake pile body bottom can adjunction steel sleeve until steel sleeve rotated be drowned into 1-2m position, whole stake pile body bottom.
Beneficial effect of the present invention:
The method of quick pile pulling under the invention provides a kind of low-headroom condition, quick pile pulling can be carried out under low-headroom condition, first use low clearance pile pulling device to be screwed in by steel sleeve and realize the separation of stake soil, the redundance on cutting amputation pile body top after more whole stake entirety being raised, backfill stake holes and tamping to design elevation, finally pull out steel sleeve, this pile pulling technique adopts steel sleeve to screw in and realizes the separation of stake soil, pile pulling construction is little on surrounding enviroment impact, obstacle pile is promoted to beyond Tunnel Passing scope, cutting amputation top redundance, thus avoid whole stake and pull out, substantially increase efficiency of construction, the method also can complete construction under the condition that headway is limited, make the obstacle pile within the scope of Tunnel Passing pull out operating efficiency greatly to improve.
