Description
Technical field
Architectural engineering is the utility model is related to, more particularly to a kind of supporting construction of foundation ditch.
Background technology
In this year, as a large amount of rises of skyscraper and the exploitation of urban underground space are used, the depth of foundation ditch is increasingly
Deep, the excavation of especially a large amount of foundation ditches is all located at the area of building dense, and this causes the support technology of foundation ditch more to seem important.
Foundation pit supporting project should ensure safety of the whole supporting construction in construction, control supporting construction and its week again
The deformation of the side soil body, to ensure the safety of surrounding enviroment.
Deep and big foundation ditch and the supporting construction to the higher foundation ditch of security requirement frequently with inner support, the inner support knot
Structure has the advantages that stress performance is preferable, rigidity is big, deformation is small and safe and reliable.Pillar construction is as in the inner supporting structure
Vertical supporting member, it has the function that important.When support is larger across space scale, column all should be set in foundation ditch
Structure, to shorten the computational length of the span of horizontal support and support beam, moment of flexure of the support beam caused by vertical load is reduced,
Ensure the intensity and stably of support.
Publication No. CN203200764U Chinese patent discloses a kind of foundation ditch pillar construction and internal support of foundation pit structure.
The column and the stand column pile in the following soil body of the bottom of foundation ditch that pillar construction is located in foundation ditch.The column lower end is embedding
In the stand column pile, the stand column pile is in strip, and its lower end outside protrudes towards outer incline, outer expanding shape structure is formed, so as to allow
Contact area between stand column pile bottom and the soil body becomes big so that and whole pillar construction can provide higher bearing capacity of pile tip,
In the case that vertical bearing capacity is constant, stand column pile can be made to be arranged to shorter structure and save material.In the mistake that supporting construction uses
Cheng Zhong, different foundation ditches, the sidewall area of foundation ditch will differ, and the quantity that now people just need to increase supporting construction ensures
The stability of foundation ditch, cost is higher, has much room for improvement.
Utility model content
