Description
Technical field
The utility model is related to Base hole supporting technology field, specially a kind of foundation ditch flexible supporting structure.
Background technology
Need to protect foundation ditch when soil property carries out excavation of foundation pit than more loose area, in case there is side wall in foundation ditch
Cave in.It is existing mainly to have to pattern foundation pit supporting structure mode, 1, cast-in-place concrete pile pattern foundation pit supporting structure form, this technology uses large type drill
March into the arena construction, drilling diameter 400-800mm, pile body is concrete perfusion technology, this technology advantage after descending reinforcing cage：Pile
Speed is fast, and strength of the mixing pile is big, and cantilever pile can be directly designed for shallow foundation hole, and prestress anchorage cable of not constructing is removed periphery pipeline from and answered
The miscellaneous influence to foundation pit support construction.This technology shortcoming：For this engineering, site area is narrow and small, and supporting construction is available
Space is small, and pile aperture cannot meet, and big machinery in this place without enough operation sides.So technology is in this work
Cannot be implemented in journey.2nd, steel sheet pile foundation ditch support form, this technology mainly pulls out shaped steel using vibration hammering, by shaped steel using impact
Power is hammered to underground, until can stop after reaching design requirement.This technology advantage：Steel sheet pile construction short time limit, process is simple,
Recycling can be extracted, compared with mixing pile etc. other to go along with sb. to guard him operating expenses low.This technology shortcoming：For this engineering, in place
Supporting construction can utilize narrow space, and the location accuracy requirements of supporting construction are high, using vibrations pile during steel sheet pile construction,
Because lower pipelines are complicated, it is easy to damage line construction during vibrations pile.Have again in the range of this place pile body and exist
Boulder bed, pole is unfavorable for steel sheet pile construction.So technology cannot be implemented in this engineering.3rd, miniature steel pipe pile support form, this
Technology mainly uses small-sized machine pore-forming, grout injection pile after lower steel pipe.This technology advantage：Miniature steel pipe pile is a kind of
The new friction pile of " path is high-strength ", it combines the advantage of steel-pipe pile and mini pile technology, foundation ditch is mainly used at present
Support engineering, pile foundation reinforcement engineering and slope reinforcement and harnessing project etc..It refers to the lower steel pipe in small-sized drilling, then
Slip casing by pressure or concrete perfusion are carried out again, so as to form a steel pipe（Cement mortar）Concrete drill hole stake is reaching reinforcing
Effect.Except the effect for possessing traditional friction pile, miniature steel pipe pile is small due to diameter, and adaptability is also strong, can neatly arrange；Its
Cost and economic performance are also superior to steel-pipe pile；Speed of application is fast, saves material, shortens the duration, while work progress is safer
It is reliable.This technology shortcoming：Because miniature steel pipe pile belongs to flexible supporting structure, its fracture resistance is poor.Therefore in supporting construction
In, miniature steel pipe pile is and anchor pole（Rope）Use cooperatively.But this engineering is due to the complicated pipeline arrangement in periphery, it is impossible to anchor pole of constructing
（Rope）, so traditional miniature steel pipe pile support form is also unable to reach design requirement in this engineering.These are all
The problem for needing us to go to solve.
The content of the invention
The purpose of this utility model is to provide a kind of foundation ditch flexible supporting structure, to solve to be proposed in above-mentioned background technology
Problem.
To achieve the above object, the utility model provides following technical scheme：A kind of foundation ditch flexible supporting structure, including a left side
Campshed and the right campshed being be arranged in parallel with left bank stake, the left bank stake are respectively and fixedly provided with the first inner support with right campshed inside upper part
Girder steel, the left bank stake is provided with the second inner support girder steel, the left bank stake and right campshed inside upper part with right campshed lower inside
It is interval between the first fixed inner support girder steel and is provided with the first inner support crossbeam, left bank stake and right campshed lower inside
The second inner support crossbeam is interval between the second inner support girder steel being provided with.
Preferably, the left bank stake has poured concrete fixed block with right campshed top.
Preferably, it is to be arranged in parallel between the first inner support crossbeam and the second inner support crossbeam.
Compared with prior art, the beneficial effects of the utility model are：The utility model uses miniature steel pipe pile Jia Neizhi
After support form supporting, design and code requirement are met, after excavation of foundation pit is fully completed, Monitoring Data is normal, and shift value exists
In early warning value, the various technical barriers that early stage runs into are completed well, entered with flexible miniature steel-pipe pile form using inner support
Row pattern foundation pit supporting structure, meets that operation side is narrow and small and the anchor pole that cannot construct（Rope）The construction difficult problem for being brought, solves well
Determined cannot construct rigid pile and anchor pole (rope) groove earth excavation support issues.
Brief description of the drawings
