Description
Technical field
This utility model belongs to foundation pit supporting construction field.
Background technology
With the continuous development of urban construction, exploitation and the construction of the underground space that is to say trend of the times.Pattern foundation pit supporting structure is just
Become an important step of Underground Construction.Widely used single support pile supporting construction, anchor in current foundation pit construction
Used as foundation pit supporting construction, to prevent, foundation ditch circumferential annular from deforming anchor supporting construction and foundation ditch collapses, it is ensured that engineering construction is applied
Work is smoothed out.Individually support pile supporting construction, anchorage pile supporting construction integral rigidity are poor, due to foundation ditch surrounding enviroment
Change, land drainage, rainfall etc. affect, and easily causing supporting construction stress increases or support system efficacy wanes, so as to cause
Foundation pit supporting system deformation is excessive, even results in foundation pit supporting system failure, seriously threatens construction safety.Generally, it is
Avoid the occurrence of above-mentioned, the campshed+inner support or anchorage pile even support pattern such as double-row pile can be selected to reach preferably
Supporting effect, but while also increase difficulty of construction and construction costs.
Utility model content
The purpose of this utility model is：A kind of reduction support pile bending and quantity of reinforcement are provided, increase support stiffness
Effective control deforms, and the anchor for saving construction costs draws inner support combined foundation ditch support structure.
The purpose of this utility model is realized by following technical proposals：
A kind of anchor draws inner support combined foundation ditch support structure, including support pile, inner support and its column, and anchor cable,
Fender pile is arranged along foundation pit walls, column and inner support relative set in foundation ditch, be connected between column and support pile at least together with
The inner support of fixed support body system is formed, at least anchor cable together, the embedment of anchor cable one end between support pile and foundation pit walls, is also associated with
Foundation pit side-wall, the other end are anchored on support pile.
Alternatively, the spacing of adjacent two support piles is equal.
Alternatively, inner support is arranged between support pile and column, and its one end is passed through with support pile and column respectively
Built-in fitting is fixedly connected, and other end connection is fastened with fixed support body.
Alternatively, in support pile and the embedded foundation ditch subsoil body of column.
Alternatively, anchor cable is inserted in the foundation pit walls soil body with 15～35 ° of angles, and termination is connected with support pile anchoring by anchor slab
Connect.
Aforementioned this utility model main formula case and its each further selection scheme can be with independent assortments to form multiple schemes,
Can adopt for this utility model and claimed scheme；And this utility model, (each non conflicting selection) select between and
Can also independent assortment and other selections between.Those skilled in the art are after the present invention program is understood according to prior art and public affairs
Know that general knowledge can understand there is multiple combination, be the claimed technical scheme of this utility model, here does not do exhaustion.
The beneficial effects of the utility model：
1) internal stay and anchor structure of different bearer ability according to formation condition and supporting construction loading characteristic, can be set；
2) using the larger advantage effective control foundation ditch local of internal stay rigidity and bulk deformation；
3) utilization reduces the quantity of reinforcement of supporting construction without the need for the anchor cable increase supporting construction fulcrum removed and cost is relatively low；
4) prestressing force and the advantage conveniently set up, reed time controll foundation pit deformation and its trend can repeatedly be applied using anchor cable；
5) inner support structure is substituted using anchor cable, reducing affects on Underground Construction, save construction costs；
6) the loaded down with trivial details inner support structure of construction is substituted using convenient construction anchor cable, accelerate speed of application and reduce the later stage to remove work
Cheng Liang.
