Description
Technical field
The utility model belongs to civil engineering foundation pit supporting construction technical field, is specifically related to a kind of drag-line Retaining Structure with Double-row Piles.
Background technology
Along with the novel urbanization planning of country advances, developing rapidly of civil engineering construction, deep foundation ditch is adapt to land resources science efficiency requirements to have become high-rise and super highrise building and infrastructure construction important component part, and its support engineering has also become the important subitem of Construction of Civil Engineering engineering.Common civil engineering Foundation Pit has undisturbed soil to put the combination of the supporting types such as slope, plate brad supporting, bolt-spary supports, pile-anchor retaining, joist anchor supporting, the supporting of campshed cantilever, steel sheet pile supporting, diaphragm wall and support supporting and wherein two kinds and two or more supporting type, and the pattern foundation pit supporting structure of current most object of construction production adopts above-mentioned supporting type.
Because city building density is more and more higher, congested in traffic, narrow field, geological conditions washability is poor.In order to make full use of soil, the contiguous new building Foundation Pit of existing building is restricted.
1, traditional slope of putting cannot be adopted to excavate, plate brad supporting and bolt-spary supports method can not be carried out again:
2, overhang mill pattern is not with inner support, anchor pole (rope), the soil pressure that the drag entirely provided by the part embedded in the soil body applies to balance foundation pit side-wall supporting and protection structure.Usually, when foundation depth is little, to can yet be regarded as a kind of supporting and protection structure type preferably from aspect analyses such as cost, construction period, construction technologies.But displacement is remarkable by the impact of geological conditions and insert depth, can not meet the requirement of complicated base pit engineering stability and controlling distortion aspect.
3, diaphragm wall adds the method supporting supporting, and as interim soil-baffling structure compared with other method costly, subsequently the lower duration of a project is long.
4, take traditional stake (wall) anchor supporting, owing to being close to the restriction of underground structure and pipeline, soil body limited width behind slope, so anchor cable angle is comparatively large, supporting effect is not good, the anchor cable and some side slopes cannot be constructed at all;
Utility model content
In order to solve the supporting of above-mentioned traditional stake (wall) anchor by soil body limited width behind slope, anchor cable angle is larger, supporting effect is not good, the anchor cable and some side slopes cannot be constructed at all, cause the excessive or performance difficulty of foundation pit deformation or anchorage etc. cannot be not suitable for the problem of foundation ditch, the utility model is in order to improve stress performance and the deformation characteristic of traditional stake (wall) anchor supporting and protection structure soldier pile, excavate the potential of supporting pile body, supporting and protection structure form is made more to be tending towards rationally reliable, meet the requirement that complicated foundation ditch props up the gear soil body, fully utilize the limited underground space, reduce environmental influence range, traditional stake (wall) anchor supporting and protection structure pattern is improved, propose a kind of drag-line double-row pile (wall) supporting and protection structure.
In order to solve the problem, the utility model is achieved by following technical scheme:
