Description
Technical field
The utility model relates to soil foundation stabilization and base form, particularly relates to soil base star centre and arm end many ropes anti_floating foundation.
Background technology
At present, most bases are resistance to compression basis, i.e. basis is primarily subjected to the vertical load of superstructure applying and meets deformation and stability requirement, is typically include isolated footing, strip footing, raft foundation etc..And anti_floating foundation mainly has heavy excavation basis, draws and dig spread foundation, explosion expanded piling basis etc.；Either heavy excavation foundation class, still draw and dig spread foundation class, the construction of explosion expanded piling foundation class all has bigger difficulty, and all there is quantities long, cost height big, time-consuming, environment is caused compared with havoc, but the problems such as the drag that can provide is limited, consolidation effect is not ideal enough, under the conditions of soil base, the problems referred to above are more prominent, and the stability on the large deformation of soil base and basis becomes the key issue that must solve.
Utility model content
Technical problem to be solved in the utility model is to provide a kind of reduction to soil base disturbance, and improves resistance to compression, pulling test strength, and optimizes loading transfer mechanism, reduces soil base star centre and arm end many ropes anti_floating foundation of soil foundation deformation simultaneously.
For solving the problems referred to above, soil described in the utility model base star centre and arm end many ropes anti_floating foundation, it is characterised in that: it includes in an embedded soil base and the overhead star member of upper surface, several beard and hair anchor pole and the backing plate matching with described beard and hair anchor pole and anchor slab；Described star member is provided with several radially-protruding semi-girder, and its center is provided with a bolthole I；The outer end of each described semi-girder is provided with a bolthole II；Described backing plate center is provided with a bolthole III；The bottom of several described beard and hair anchor poles is all anchored, and its top passes through described bolthole I or the described bolthole II of described star member respectively, and the described bolthole III passing through described backing plate connects together with described anchor slab；Described beard and hair anchor pole is made up of resistance to drawing-down silk, and the waterproof explosive equipped with detonator is tied up in the bottom of this resistance to drawing-down silk, and makes described resistance to drawing-down silk be uniformly distributed in around equipped with the described waterproof explosive of described detonator along circumferential direction.
Described soil base is one or more in mud, muck soil, cohesive soil, silt, loess, sand, artificial earth fill and foundation of gravelly soil.
Described star member is provided with fixture.
The quantity of described semi-girder is three and more than three.
An injected hole is had on described backing plate.
The thickness of the diameter of the described beard and hair anchor pole that the thickness of the diameter of the described beard and hair anchor pole being placed in bolthole II described in several described semi-girder, length and the described backing plate matching with it and anchor slab is respectively less than placed in bolthole I described in described star member center, length and the described backing plate matching with it and anchor slab.
The thickness of the diameter of the described beard and hair anchor pole being placed in bolthole II described in several described semi-girder, length and the described backing plate matching with it and anchor slab is all identical.
The utility model compared with prior art has the advantage that
1st, first, the impact compress consumingly at the bottom of drilling hole of detonation gas produced by explosive charge in the utility model, cause boring end surrounding ground base crushed, form the enough cavitys of size, forming the anchoring body with bottom enlarged footing by slip casting, the anchor force being provided can sufficiently achieve makes superstructure stable；They are two years old, detonation gas produced by explosive charge is to drilling hole subsoil ground strong effect, make surrounding ground base at the bottom of hole be compressed, the crack in soil base is pushed open simultaneously, the physical and mechanical property of internal soil base (foot of hole surrounding ground base) after filling and injecting slurry body, will be improved；They are three years old, at once detonate after boring hole-bottom slurry-injection buried explosive, while detonation strength drives surrounding ground basic capsule gap at the bottom of injecting cement paste filling borehole, scatter in the resistance to drawing-down crack in the wall of a borehole and soil base for the silk driving beard and hair anchor pole, especially the resistance to drawing-down silk of beard and hair anchor pole is driven to penetrate among boring end surrounding ground basic capsule gap dearly by the strong power-actuated injecting cement paste of detonation, injecting cement paste by anchor rod anchored for beard and hair in boring in while, cavity at the bottom of tapping hole and soil basic capsule gap, formed with the injecting cement paste of filling in holing as core, draw and attenuate the comprehensive of silk extension by the injecting cement paste in soil basic capsule gap and beard and hair anchor pole are resistance to, three-dimensional, compound anchoring, the safety making engineering is protected.
2nd, the utility model simple in construction, radical change construction and base form, save investment significantly, decreased spoir, make environment be protected.
