Foundation pit supporting structure is a temporary retaining facility

how to reduce the engineering cost and improve the construction speed under the precondition of ensuring the safety is a common concern. To satisfy the engineering demand

a new type of foundation pit supporting structure

cross-shaped assembled foundation pit supporting structure

is proposed

which is safe

rapid

low cost

recyclable and environmentally friendly. In this paper

the structure selection and calculation method of the lattice element are introduced. The field test relying on a project in new Wuxiang district

Nanning

Guangxi province

shows that the experimental values are similar to the calculated values. It proves the correctness of the proposed design method. With the support of the foundation pit supporting structure

the stability of foundation pit

deformation of foundation pit and the strength of support structure all can meet the requirements of specification

so it can be applied in similar projects in the future.
