Background technology
With the quickening of urbanization process and the increasingly reduction of land resource, all kinds of buildings in city start to send out to the underground space
Exhibition, the basic more and more deeper of building is embodied in, the increasing floor space particularly occurred in the last few years is big, flat
The complex-shaped ultra-deep foundation pit engineering in face.Foundation pit support plan is essential one during Foundation Pit Construction, right
In the foundation ditch that foundation ditch area is big, cutting depth is deep, earth excavation difficulty is big, its supporting scheme need to mainly solve following point：①
Solve the generous amount earth excavation transportation problem of deep basal pit, working face and passage are provided for digging machine and earth moving vehicles；2. solve
The problem of site operation narrow field, place is provided for placing of material and processing；3. solves deep big foundation pit support stiffness deficiency
Problem, control and reduction foundation pit deformation, improve the safe operating mode of foundation ditch；4. simultaneously it is also contemplated that economy, convenient construction and environment
The influence of the other factors such as influence.Deep foundation pit support generally use armored concrete is used as support to support or angle brace at present, and sets
Armored concrete trestle is put, as the earthwork and transport of materials passage, and irrational design can not only increase financial cost, can also
Influence be unearthed efficiency, delay construction speed.Therefore, it is necessary to propose optimal branch for multi-form huge ultradeep foundation pit engineering
Trestle system is supportted, so as to ensure the unearthed efficiency of pattern foundation pit supporting structure safety, raising, reduction engineering cost, shorten the cycle of being unearthed.Foundation ditch fills
With formula steel trestle and construction method, such a support bridge system has great applicability in pit earthwork digging process.
Utility model content
Goal of the invention of the present utility model is a kind of steel lattice column of design and bored concrete pile attachment structure, realizes steel latticework and filling
Note stake is reliably connected, and improves steel lattice column bearing capacity and stability.
The utility model is for the technical scheme realized its technical purpose and used：A kind of steel lattice column connects with bored concrete pile
Binding structure, including connection positioning bar, are that positioning bar is connected between steel latticework and steel reinforcement cage in described connection positioning bar, described
