Abstract
The invention discloses a kind of construction method of pile pulling, prepare before comprising the steps: A, pile pulling; B, be separated old pile foundation; C, pile pulling.Advantage of the present invention is: require low to construction plant, efficiency of construction is high; Safe and reliable, low noise little to periphery soil disturbance, shockproof, pollution-free; Workable, do not need the main equipments such as crane, reduce construction cost.
Description
Technical field
The present invention relates to a kind of construction method of extracting old foundation pile of building engineering field, in particular, relate to a kind of low noise, the construction method of simple pile pulling of constructing.
Background technology
At present, along with the quickening of urban construction and development speed, original most of communal facilities can not meet user demand, particularly evident in urban traffic and housing construction, just need again to remodel and expand original building, in dismounting, reconstruction and enlarging process, the underground pile foundation all inevitably related to is removed.But due to the feature of urban renewal, near the existence of other often adjoint building and obstruction, in removal and job site, often obstruction is numerous, the main equipments such as the pipe bit machine that conventional pile pulling technology uses and crane cannot enter job site, need that the main equipments such as rear crane are cleared up to scene and just can enter construction, delay construction speed, and wasting manpower and material resources.
Summary of the invention
The present invention is directed to the deficiencies in the prior art, and provide a kind of, low noise little to periphery soil disturbance, shockproof, pollution-free, construction is flexible, the construction method of the pile pulling that efficiency of construction is high.
In order to achieve the above object, this invention takes following technical scheme:
A construction method for pile pulling, comprises the steps:
Prepare before A, pile pulling:
Select the tonnage of fork truck according to the weight of old pile foundation, fork truck is arranged on old pile foundation limit; Set up tripod, angle for tripod is fixed on ground, install movable pulley in the center of tripod, being sling by pipe bit head by movable pulley is arranged on directly over old pile foundation, drilling pipe is arranged on pipe bit head lower end, the old pile foundation center of circle of drilling pipe perpendicular alignmnet;
B, be separated old pile foundation:
Start under pipe bit head drives drilling pipe and bore, the degree of depth that drilling pipe pierces is not less than the degree of depth of old pile foundation, then extracts drilling pipe dismounting pipe bit head out;
C, pile pulling:
Steel wire loop centre position is fixed on the lower end of old pile foundation, one end of steel wire loop is fixed on the jaw of fork truck, and the other end is fixed on movable pulley; Fork truck and movable pulley alternately coordinate firmly, old pile foundation are extracted.
Described tripod is provided with base, and described base is fixed by expansion bolt and ground.The internal diameter of described drilling pipe is not less than the external diameter of old pile foundation.The position of the old pile foundation of distance of described angle steel pile is not less than 5 meters.Described steel wire loop and angle steel pile are that 8 words are overlapping fixing.
Beneficial effect of the present invention: (1) requires low to construction plant, and efficiency of construction is high; (2) safe and reliable, low noise little to periphery soil disturbance, shockproof, pollution-free; It is (3) workable, do not need the main equipments such as crane, reduce construction cost.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention is described in further detail.
As shown in the figure: in the construction method of a kind of pile pulling of the present invention, tripod 1, pipe bit head 2, drilling pipe 3, old pile foundation 4, movable pulley 5, angle steel pile 6, steel wire loop 7, fork truck 8.
The construction method of a kind of pile pulling of the present invention, comprises the steps:
Prepare before A, pile pulling:
Select the tonnage of fork truck 8 according to the weight of old pile foundation 4, fork truck 8 is arranged on old pile foundation 4 limit; Set up tripod 1, and an angle for tripod 1 is fixed on ground, described tripod 1, be made up of seamless steel pipe, its wall thickness and height determine according to the degree of depth preparing the old foundation pile 4 pulled out, and tripod 1 is provided with base, and described base is fixed by expansion bolt and ground.In the center of tripod 1, movable pulley 5 is installed, being sling by pipe bit head 2 by movable pulley 5 is arranged on directly over old pile foundation 4, drilling pipe 3 is arranged on pipe bit head 2 lower end, drilling pipe 3 perpendicular alignmnet old pile foundation 4 center of circle, the internal diameter of described drilling pipe 3 is not less than the external diameter of old pile foundation 4;
B, be separated old pile foundation 4:
By tripod 1, pipe bit head 2 and drilling pipe 3 suspention are lifted, the old pile foundation 4 that drilling pipe 3 mouthfuls of perpendicular alignmnets are residual, start pipe bit head 2, utilize the rotation of drilling pipe 3, press down, cut and be separated the earth of old pile foundation 4 with surrounding, the degree of depth that drilling pipe 3 pierces is not less than the degree of depth of old pile foundation 4, then extracts drilling pipe 3 out and remove pipe bit head 2; Then by two steel wire loops 7, along old pile foundation 4 head down, by the gap of cutting and separating, old pile foundation 4 is fixedly entangled firm;
C, pile pulling:
Steel wire loop 7 is fixed on the lower end of old pile foundation 4, one end of steel wire loop 7 is fixed on the jaw of fork truck 8, and the other end repeats to fix by 8 word interior extrapolation methods through movable pulley 5 and angle steel pile 6, and described angle steel pile 6 is not less than 5 meters apart from the position of old pile foundation 4; Fork truck 8 and movable pulley 5 alternately coordinate firmly, and pile pulling starts, and fork truck 8 and movable pulley 5 alternately stressed lifting, tighten up wire rope at lifting process; When fork truck 8 is lifted to certain altitude, movable pulley 5 tightens up thereupon, and make steel wire loop 7 be in stress always, at this time fork truck tightens up wire rope again, again promotes, when old proposition ground, pile foundation 4 upper end, rope to be fastened in old pile foundation 4 upper end, fell draw for extracting rear pile foundation, then old pile foundation 4 extracted, traction was fallen; The hole of the old pile foundation 4 finally stayed, will backfill in time, tamp, and prevents personnel from falling.
The construction method of a kind of pile pulling of the present invention is used in crane and the unapproachable job site of main equipment, and can carry out old pile foundation efficiently and extract work, safe and reliable, efficiency of construction is high, workable, can reduce construction cost.
