The utility model content
The purpose of this utility model is to provide a kind of deep big foundation pit reinforced concrete annulus truss horizontal support structure, is applicable to that diameter is the deep big foundation pit of 150m-250m.Materials are economized, and are both economical, easy construction and reduction of erection time.
For achieving the above object, the utility model adopts following technical proposals:
A kind of deep big foundation pit reinforced concrete annulus truss horizontal support structure, comprise perpendicular fender body and water-stop curtain of listing in the foundation ditch perisporium, and the horizontal support structure of braced cuts body, it is characterized in that foundation ditch is circular dark hollow place, its maximum gauge is 150m-250m, horizontal support structure is a steel concrete second ring annulus truss horizontal support framework, the structure of described second ring annulus truss horizontal support framework is: a big steel concrete annulus beam is fixed in the fender body top, middle steel concrete annulus beam is supported by stand column pile and is positioned on the same horizontal plane of described big steel concrete annulus beam, described two big, be connected to form horizontal second ring annulus truss by reinforced concrete coupling beams between the middle steel concrete annulus beam.
The structure of above-mentioned horizontal second ring annulus truss is: the second ring annular network that is connected to form the triangle mesh between described reinforcing bar soil two annulus beams with the described reinforced concrete coupling beams greater than the length of two annulus case bays.
Above-mentioned second ring annulus truss horizontal support frame underneath also has one three annular circular ring truss horizontal support framework, its structure is: the outside of a big steel concrete annulus beam props up fender body, and by hanging muscle and big steel concrete annulus beam is fixedlyed connected with described fender body, a middle steel concrete annulus beam is arranged in the below of the steel concrete annulus beam of described second ring annulus truss horizontal support framework, support by stand column pile, also have a little steel concrete annulus beam to support by stand column pile, described big, in, little steel concrete annulus beam all on same horizontal plane, described three big, in, little steel concrete annulus beam is connected to form level three annular circular ring truss by reinforced concrete coupling beams.
The structure of above-mentioned level three annular circular ring truss is: between described big steel concrete annulus beam and the middle steel concrete annulus beam and between middle steel concrete annulus beam and the little steel concrete annulus beam, all connect into three annular circular ring shape networks of triangle mesh with the described reinforced concrete coupling beams greater than the length of adjacent two annulus case bays.
The utility model compared with prior art, have following conspicuous substantive distinguishing features and advantage: foundation ditch of the present utility model is round dark hollow place, the ring beam maximum gauge is 150m-250m, horizontal support structure is the fixedly connected steel concrete second ring annulus truss in fender body and stand column pile top, can also in foundation ditch, install three annular circular ring truss again additional, its annulus truss horizontal support structure has solved the stability and supporting frame self the integral rigidity needs of Large and Deep Foundation Pit body.Adopt the annulus truss, all rod members mainly bear axial force, and bending moment is little, and the rod member upper stress is more even, so materials province is from heavy and light, rational in infrastructure.Adopt the annulus trussed construction; remove the planar surface encloses structure truss of prior art; then be convenient to excavation construction to deep big foundation pit; can adopt central island to stay the shoveling mode of soil; the principle of facade layering, plane piecemeal, segmentation is carried out soil excavation; help extensive mechanized, obviously the reduction of erection time, also alleviate pollution environment.
