Description

Upper plate-anchor pole-ball basis

Technical field

The utility model relates to soil foundation stabilization and base form, particularly relates to upper plate-anchor pole-ball basis.

Background technology

At present, overwhelming majority basis is resistance to compression basis, i.e. basis is primarily subjected to vertical load that superstructure applies and full Foot deformation and stability requirement, be typically include isolated footing, strip footing, raft foundation etc..And anti_floating foundation mainly has greatly Excavation foundation, draw dig spread foundation, explosion expanded piling basis etc.；Either heavy excavation foundation class, still draws and digs spread foundation class, explosive expansion The construction of pile foundation class all has bigger difficulty, and all there is quantities long, cost height big, time-consuming, causes environment bigger Destroy, but the problem 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 Go out, 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, resists Pull out intensity, and optimize loading transfer mechanism, reduce the upper plate-anchor pole-ball basis of soil foundation deformation simultaneously.

For solving the problems referred to above, upper plate-anchor pole described in the utility model-ball basis, it is characterised in that: it includes one In embedded soil base and the upper surface upper plate concordant with ground, one or more anchor pole and the backing plate matching with described anchor pole and Anchor slab；Described upper plate is polygon, and its center is provided with a bolthole I；Described backing plate center is provided with a bolthole III；Described Anchor pole includes the body of rod and the several poles hinged with described body of rod bottom；The binding of several described poles is equipped with the bar shaped water resistant of detonator Explosive, the two is as consistent with described body of rod axis in its axis of one；The bottom of described anchor pole and several described pole are all anchored, Its top is each passed through the described bolthole I of described upper plate correspondence position, and passes through described bolthole III and the institute of described backing plate State anchor slab to connect together.

Described soil base is mud, muck soil, cohesive soil, silt, loess, sand, artificial earth fill and foundation of gravelly soil In one or more.

Described upper plate is provided with fixture.

An injected hole is had on described backing plate.

Each angle of described upper plate is equipped with a bolthole II；And the top of described anchor pole is each passed through described upper plate pair Answer the described bolthole II of position, and the described bolthole III passing through described backing plate connects together with described anchor slab.

The center of described upper plate is provided with a bolthole I, and each angle is provided with a bolthole II；The top of described anchor pole It is each passed through described bolthole I and the described bolthole II of described upper plate correspondence position, and pass through the described anchor pole of described backing plate Hole III connects together with described anchor slab (8).

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, form band bottom armored concrete by slip casting and expand The anchoring body of major part, the anchor force being provided can sufficiently achieve makes superstructure stable；Its two, detonation produced by explosive charge Gas, to drilling hole subsoil ground strong effect, makes surrounding ground base at the bottom of hole be compressed, pushes away the crack in soil base simultaneously Open, the physical and mechanical property of internal soil base (foot of hole surrounding ground base) after filling and injecting slurry body, will be improved；Its three, By by anchor rod body bottom pole with explosive be placed in cavity at the bottom of drilling hole detonating charge, detonation strength drives anchor The pole that club shaft rises and bottom is hinged therewith is scattered around hinged, subsequently anchor rod body and its end under downward Action of Gravity Field End pole is all fallen, and just stops falling when bottom pole touches cavity wall at the bottom of hole, and several poles are supported at the bottom of hole with opening On cavity, afterwards by cavity slip casting at the bottom of whole hole, form the spherical enlarged footing of armored concrete, and Shi Hanzhang and again Slip casting, builds anchoring comprehensive, three-dimensional, compound.

2nd, the utility model simple in construction, radical change construction and base form, save investment significantly, decreased Spoir, makes environment be protected.
