Background technology
With the rapid development of urbanization, the traditional direct-buried mode of municipal pipeline has exposed problems, serious to hinder
The development in city is come into being to solve problem above pipe gallery this intensive building.Pipe gallery will be various
The cables such as municipal pipeline and communication concentrate laying, can successive elimination " road slide fastener ", " aerial cobweb " the problems such as and
Urban carrying capacity is improved, is the necessarily guarantee of new city development.
Pipe gallery construction at this stage is all concentrated on substantially in the big city of population and building dense.It is built in these places
If pipe gallery mainly faces two hang-ups：Pipe gallery excavation of foundation pit size is restricted so that outboard template sets up space and has
Limit and pattern foundation pit supporting structure are more difficult.
" a kind of reusable pipe gallery pattern foundation pit supporting structure and the outer module of structure of the patent No. " 201620425135.7 "
Close structure " disclose a kind of vertical supporting and retaining system of foundation pit by pipe gallery foundation pit both sides and structure external mold assembled unit and horizontally-supported
The composite structure that structure is formed.The vertical supporting and retaining system of foundation pit includes a secondary three axis cement with structure external mold assembled unit in this structure
Native mixing pile, this more difficulty of constructing in city, first cement mixing method can generate larger vibration in construction, secondly
Cement mixing method cannot be removed after the completion of pipe gallery construction, cause the pollution and waste of urban underground space.
Generally speaking, existing pattern foundation pit supporting structure and cast outer mold structure all independent actions, occupied space is big, and pattern foundation pit supporting structure knot
Structure can not be removed, and pollute urban underground space.
Utility model content
For problems of the prior art, the utility model provides a kind of assembly type pipe gallery base of recycling

Compared with prior art, the utility model has technique effect beneficial below：
The composite structure that a kind of pipe gallery pattern foundation pit supporting structure of recycling of the utility model is combined with structure external mold, by
Standard component is assembled and is removably suitable in High-Density Urban Area, is arranged on the steel template structure of inside by inside to pipe gallery
Limitation as pipe gallery exterior sheathing, can be played to pipe gallery pattern foundation pit supporting structure again by the supporting role to firm sheet pile
Two supporting defence lines act on, and have double action.The vertical supporting of foundation pit simultaneously and structure external mold assembled unit and horizontally-supported knot
Structure component is that the standard steel member of repeatable splicing and dismounting solves foundation pit supporting construction and can not remove, pollution Urban Underground
The problem of space, overcome existing pattern foundation pit supporting structure and cast outer mold structure independent action, occupied space is big, it is difficult to the problem of constructing, together
When accomplished construct instrument reuse, save working sources.
Further, by the setting for the connector that can be dismantled, not only ensure that between steel sheet pile and steel form can
It is connected by gap, and assembling installation can be improved and recycle efficiency, the identical structure of different location can exchange, general
Property it is high.
Further, by the setting of threaded rod and nut, once-through operation can be realized, to the same of steel sheet pile and steel form
When connection fix.
Further, by mating between steel pipe and Guan Liang, the dismounting of horizontal support structure is greatly improved
Performance, cooperation is simple, and support performance is good.
