Abstract
The utility model discloses a deep steel sheet net dado section of thick bamboo suitable for soft soil area bored concrete pile of driling, it includes that the steel sheet net protects a section of thick bamboo, steel annular lug and hangs the muscle, its characterized in that steel sheet net protects a section of thick bamboo for open cylindrical barrel from top to bottom, protects at the steel sheet net that an upside is fixed to be set up threely or six steel annular lugs, wears to hang on the steel annular lug and hangs the muscle. The utility model provides an engineering quality has been guaranteed to the frictional resistance that a deep steel sheet net dado section of thick bamboo suitable for soft soil area bored concrete pile of driling, simple manufacture, convenient operation prevents behind clear hole because mud proportion descends, opposite side pressure ratio increase in the stake and the necking down appears and the hole phenomenon of collapsing behind concrete placement, does not slacken the stake.
Description
Technical field
The utility model belongs to building operations servicing unit, especially relates to a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile.
Background technology
Carry out bored pile construction in soft clay area, because construction area distribution mucky soil and stream mould the soft layers such as (drift sand) layer, when carrying out bored pile construction, aperture necking down and collapse hole phenomenon often can occur, very large impact is caused on the quality of stake.Usually, the soft layer at earth's surface place solves by the mode burying steel pile casting underground, and necking down darker under appearing at earth's surface and collapse hole phenomenon, effective solution also not relevant at present.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile, make simple, easy to operate, not only effectively can solve the necking down occurred in construction and collapse hole phenomenon, and after concreting, do not slacken the frictional resistance of stake, ensure that workmanship.
For achieving the above object, the utility model proposes a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile, it comprises expanded metal lath casing, steel annular hanger and hangs muscle, expanded metal lath casing is the cylindrical tube opened wide up and down, on the upside of expanded metal lath casing, be fixedly installed three or six steel annular hangers, steel annular hanger wear extension and hangs muscle, described expanded metal lath casing adopts rectangular steel plates net volume system to form, rectangle steel expanded metals adopts carbon steel or zinc-plated or copper plated material, thickness is 2mm ~ 5mm, mesh size is 20mm, width is 1.2m, rectangle steel expanded metals side overlap joint end face adopt steel wire symmetry to install two hooks, corresponding opposite side overlap joint end face adopt steel wire to install two links, expanded metal lath both sides are overlapped, and hook is buckled in link, expanded metal lath casing can be rolled into, the diameter of expanded metal lath casing can adjust according to the grout pile footpath of reality, 20mm is reduced than design stake footpath, to put into stake holes smoothly, described to be fixedly installed on trisection point or six Along ents that on the upside of expanded metal lath casing three or six steel annular hangers be separately positioned on expanded metal lath casing circumference, to hang the reinforcing bar that muscle can adopt Φ 6mm, after hanging the bending of muscle upper end, hang over bored pile bead.
Use described in the utility model a kind of be applicable to the deep layer expanded metal lath retaining wall cylinder of soft clay area bored pile before, necking down (collapse hole) position is accurately measured by coiling instrument after testing, determine to hang muscle length according to the mensuration degree of depth again, expanded metal lath casing is put into stake holes revolution is timely afterwards; Also can, when to pile driving construction, namely carry out a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile described in the utility model is installed, the generation of prevention necking down or collapse hole phenomenon.
A kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile that the utility model proposes, make simple, easy to operate, prevent behind clear hole because mud balance declines, in stake, opposite side pressure ratio increases and occurs necking down and collapse hole phenomenon, after concreting, do not slacken the frictional resistance of stake, ensure that workmanship.
Accompanying drawing explanation
Fig. 1 is a kind of deep layer expanded metal lath retaining wall barrel structure schematic diagram being applicable to soft clay area bored pile that the utility model proposes.
Detailed description of the invention
See accompanying drawing, a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile, it comprises expanded metal lath casing 1, steel annular hanger 2 and hangs muscle 3, expanded metal lath casing is the cylindrical tube opened wide up and down, on the upside of expanded metal lath casing, be fixedly installed three or six steel annular hangers, steel annular hanger wear extension and hangs muscle, described expanded metal lath casing adopts rectangular steel plates net volume system to form, rectangle steel expanded metals adopts carbon steel or zinc-plated or copper plated material, thickness is 2mm ~ 5mm, mesh size is 20mm, width is 1.2m, rectangle steel expanded metals side overlap joint end face adopt steel wire symmetry to install two hooks 5, corresponding opposite side overlap joint end face adopt steel wire to install two links 4, expanded metal lath both sides are overlapped, and hook is buckled in link, expanded metal lath casing can be rolled into, the diameter of expanded metal lath casing can adjust according to the grout pile footpath of reality, 20mm is reduced than design stake footpath, to put into stake holes smoothly, described to be fixedly installed on trisection point or six Along ents that on the upside of expanded metal lath casing three or six steel annular hangers be separately positioned on expanded metal lath casing circumference, to hang the reinforcing bar that muscle can adopt Φ 6mm, after hanging the bending of muscle upper end, hang over bored pile bead.
Use described in the utility model a kind of be applicable to the deep layer expanded metal lath retaining wall cylinder of soft clay area bored pile before, necking down (collapse hole) position is accurately measured by coiling instrument after testing, determine to hang muscle length according to the mensuration degree of depth again, expanded metal lath casing is put into stake holes revolution is timely afterwards; Also can, when to pile driving construction, namely carry out a kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile described in the utility model is installed, the generation of prevention necking down or collapse hole phenomenon.
In in wide core shining sun 200MW wind energy turbine set expanding branch grouting pile construction, adopt deep layer expanded metal lath casing to efficiently solve 3 ~ 4m place under earth's surface, stake position, local and mould the necking that (drift sand) layer occurs due to stream, ensure that construction speed and workmanship.
A kind of deep layer expanded metal lath retaining wall cylinder being applicable to soft clay area bored pile that the utility model proposes, make simple, easy to operate, prevent behind clear hole because mud balance declines, in stake, opposite side pressure ratio increases and occurs necking down and collapse hole phenomenon, after concreting, do not slacken the frictional resistance of stake, ensure that workmanship.
