Description
Technical field
The utility model belongs to technical field of building construction, and in particular to arrives a kind of interim coagulation of City Subway Station foundation pit
Device is cut and disassembled in native inner support.
Background technique
In the construction of city underground deep basal pit Project design, to ensure construction safety, support form is generally used in foundation pit
" bracing members+steel purlin " or " concrete support+concrete breast beam " or both mix support construction, especially by engineering water
When text, geological conditions or surrounding enviroment condition limit, gib mostly uses concrete supporting structure in deep basal pit, but how to pacify
Full dismantling concrete inner supporting structure is one of important content of security of foundation ditch construction.Traditional bracing demolition method, generally
It perhaps crusher machine mode or is manually abolished using the mechanical tools strength such as pneumatic pick or using rope sawing using demolition blasting
Cut piecemeal dismounting.Chinese patent CN108166500A discloses one kind deep foundation ditch concrete cutting disassembling and recovery method near a river,
Concrete inner support is supported using split heads, bores hole for hoist in the supporting beam of inner support, is sawed using rope and carries out static(al) cutting, will cut
The supporting beam of inner support after cutting goes out construction site using hole for hoist collective conveyance and is recycled, and constructing operation is simple,
Concrete cutting disassembling and recovery method are efficient, safe and environment-friendly, and environmental pollution is lower, but this method needs to carry out largely
Concrete drill core takes Kong Zuoye, and construction cost is high.
Summary of the invention
The technical problem to be solved by the utility model is to overcome the deficiencies in the prior art, provide a kind of design rationally,
Constructing operation is simple, safe and environment-friendly, the lower foundation pit concrete breast beam fast dismounting device of environmental pollution.
Solve above-mentioned technical problem the technical solution adopted is that: foundation pit surrounding is provided with fender post, goes along with sb. to guard him stake top and is provided with
Crown beam is arranged at intervals with multilayer waist rail inside foundation pit, is arranged at intervals with supporting beam inside foundation pit on waist rail, vertically passes through inside waist rail
It wears waist rail and is arranged at intervals with several waist rail holes for hoist, be vertically arranged at intervals with several cut in the waist rail protective layer of fender post side
Hole is cut, runs through supporting beam in supporting beam and is vertically arranged at intervals with several supporting beam holes for hoist.
The waist rail hole for hoist, cutting hole, supporting beam hole for hoist of the utility model are all made of hard straight PVC pipe, waist rail lifting
Hole, supporting beam hole for hoist tubing caliber are 100~200mm, and cutting hole tubing caliber is 20~30mm.
The waist rail hole for hoist of the utility model, cutting hole, supporting beam hole for hoist both ends be all made of adhesive tape sealing.
The waist rail hole for hoist of the utility model is vertically provided at the center in waist rail cross section, the transverse direction in distance cutting hole
Distance is 30cm.
The utility model has the advantage that compared with the prior art
The utility model uses the preparatory installation settings before the supporting beam of deep basal pit inner support, waist rail concreting and hangs
Hole, cutting hole are filled, a large amount of concrete drill hole core work is saved, improves construction efficiency, the utility model has design
Rationally, of simple structure and low cost, using flexible can promote and apply in the Demolition Construction of concrete temporary component.
