Example Embodiment

[0025] The technical solution of the present invention will be described in detail below in conjunction with the drawings:

[0026] Such as figure 1 , figure 2 As shown, a prefabricated double-row steel pile foundation pit supporting structure is characterized in that it includes a front row of steel piles 1, a rear row of steel piles 2, and a reinforcing member 3. Between the front row of steel piles 1 and the rear row of steel piles 2 Reinforcement members 3 are arranged, and the reinforcement members 3 are distributed and connected to the front row of steel piles 1 and the rear row of steel piles 2 by fasteners 4.

[0027] The construction method of the fabricated double-row steel pile foundation pit supporting structure based on the present invention includes the following steps:

[0028] Step 1: According to site conditions and calculation analysis, determine the model, pile length, and pile spacing of the front row of steel piles 1, determine the model, pile length, and spaci...

Abstract

The invention discloses an overall assembly-type double-row steel pile foundation pit supporting structure and relates to the technical field of traffic and civil construction projects, in particular to the technical field of the overall assembly-type double-row steel pile foundation pit supporting structure. The overall assembly-type double-row steel pile foundation pit supporting structure comprises a front row steel pile, a back row steel pile and reinforced components, wherein the reinforced components are arranged between the front row steel pile and the back row steel pile. The reinforced components are distributed between the front row steel pile and the back row steel pile through the connection of fasteners. The overall assembly-type double-row steel pile foundation pit supporting structure is capable of achieving horizontal stiffness of the double-row steel pile foundation pit supporting structure and controlling deformation of a foundation pit and adapting a purpose of deeper foundation fit projects.

Description

[0001] technical field [0002] The invention relates to the technical field of traffic and civil construction engineering, in particular to the technical field of an integrally assembled double-row steel pile foundation pit support structure. [0003] Background technique [0004] The double-row pile support structure means that two rows of parallel piles are set in the foundation soil, the pile bodies of the front and rear rows are arranged in a rectangular or plum blossom shape, ring beams are set on the top of the two rows of piles, and connected by connecting beams, along the parallel direction of the pit wall , forming a gate-shaped space structure, which is a space statically indeterminate structure with high overall rigidity, which can effectively limit the deformation of the foundation pit. Under the action of complex and changeable external loads, it can automatically adjust the internal force of the support structure itself to adapt to complex And often unpredict...
