Abstract

The invention relates to a method for jacking a steel casting of a bored pile by using jacks, which comprises the flowing steps of: placing two smooth sleepers horizontally on the ground on two sides of the jacket steel casting, wherein the two sleepers are vertical to the connecting line of two lifting lugs of the steel casting; (b) placing a jacket on each sleeper; arranging a cross beam on the two jackets; arranging a steel wire rope on the cross beam above each lifting lug, wherein the steel wires pass through the lifting lugs of the steel casting and the two free ends of the steel wire ropes are fixedly jointed; and (c) turning the jackets by two persons at the same time to jack the cross beam up so that the steel casting is pulled up by the cross beam through the steel wire ropes. The invention has the advantages of simple structure, convenient and simple operation, high safety and reliability, no limit by places, fast construction and low cost.

Description

Pull bored pile steel casing method with jack
Technical field
The present invention relates to a kind of device of pulling, relate in particular to and a kind ofly pull bored pile steel casing method with jack.
Background technology
Bad at geological condition, the boring in the hole of easily collapsing needs castinplace pile.In general before boring, need to take overlength steel casing to carry out supporting.But because the steel casing is buried underground too dark; very big of static friction force; generally all more than 100 tons; adopt existing equipment; adopt crane or other crane gear as pull steel protective-cylinder; general do not have so big lifting force, work plane also differs and meets the demands surely simultaneously, usually can cause and pull out the casing of not tapping, and sometimes also can cause serious economy loss.
Summary of the invention
The objective of the invention is to address the above problem and provide a kind of simple in structure, simple operation, safe and reliable, not limited by the place, what the fast expense of constructing was low pulls bored pile steel casing method with jack.
The present invention solves the problems of the technologies described above the technical scheme that is adopted:
It comprises the steps: a) with two level and smooth sleepers respectively level be placed on the ground of the steel casing both sides of being pulled the line of two hangers of the steel casing that described two sleepers are vertically pulled; B) place a jack on each sleeper, a crossbeam is set on two jack, be positioned on the crossbeam of each hanger top and be equipped with a wire rope, the hanger of steel wire penetrating steel casing, and affixed wire rope two free ends; C) two people shake jack simultaneously, the jack stand crossbeam, and crossbeam pulls up the steel casing by wire rope.
Above-mentioned wire rope two free ends are provided with steel wire clamp, with steel wire clamp two free ends are connected.
Compared with prior art, the present invention has obtained following technique effect:
1, the top power of jack generation satisfies fully and pulls static friction force all at the overlength steel casing more than 100 tons much larger than the power of hanging of crane gear;
2, jack is pulled does not have place restriction, as then can't the erect-position place at narrow and small crane gear, can well work yet;
3, the jack stroke is slower, control easily, and security performance is very good;
4, the package unit expense is very low, two 200 tons of jack, a crossbeam (can select i iron for use) and two wire rope exactly, and the turnover utilization rate is high.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is the vertical view of Fig. 1.
Wherein: 1-crossbeam, 2-steel wire clamp, 3-wire rope, 4-steel casing, 5-hanger, 6-jack, 7-ground, 8-sleeper.
The specific embodiment
Further specify embodiments of the invention below in conjunction with accompanying drawing.
Embodiment 1
Referring to Fig. 1-2, a kind ofly pull bored pile steel casing method with jack, it comprise the steps: a) with two level and smooth sleepers 8 respectively level be placed on the ground 7 of steel casing 4 both sides of being pulled the line of two hangers 5 of the steel casing that described two sleepers are vertically pulled; B) on placement one jack 6, two jack crossbeam 1 (can select i iron for use) is set on each sleeper, the crossbeam of each hanger top is provided with a wire rope 3, the hanger of steel wire penetrating steel casing, and affixed wire rope two free ends; Preferably, can be provided with steel wire clamp 2, two free ends be connected with steel wire clamp at wire rope two free ends; C) two people shake jack simultaneously, the jack stand crossbeam, and crossbeam pulls up the steel casing by wire rope.The steel casing only need be stirred, and static friction force is converted into the dynamic friction resistance after stirring, because the dynamic friction resistance is minimum, can utilize the fishing tackle of rig itself that the steel casing is pulled up again.
Protection scope of the present invention is not limited to the above embodiments, and obviously, those skilled in the art can carry out various changes and distortion and do not depart from the scope of the present invention and spirit the present invention.If these changes and distortion belong in the scope of claim of the present invention and equivalent technologies thereof, then the present invention also is intended to comprise these changes and is out of shape interior.
