specific Embodiment 1

[0035] Specific embodiment one: as figure 1 , figure 2 , Figure 4 , Figure 5 As shown, an assembled crown-beam structure for the retaining wall of a foundation pit includes a plurality of cover plates 4 and a plurality of steel beam assemblies 2 .

[0036] The retaining wall of the foundation pit includes a plurality of wall profile steels 1.2 distributed sequentially along the length direction of the retaining wall of the foundation pit, and the upper end of the wall profile steel protrudes above the ground surface. In this embodiment, the wall profile steel 1.2 is a round steel pipe or a square steel pipe. In this embodiment, the retaining wall of the foundation pit also includes a steel purlin girder 1.4, and the purlin beam is located inside the assembled crown beam structure of the retaining wall of the foundation pit.

[0037] Specifically, the retaining wall of the foundation pit in this embodiment is an underground cement-soil continuous wall, or an assembled ...

Abstract

The invention discloses an assembled crown beam structure of a foundation pit enclosure wall and aims to provide the assembled crown beam structure which is not only capable of ensuring overall strength of the foundation pit enclosure wall, but also short in construction cycle, convenient to construct and convenient to disassemble and can be repeatedly assembled, disassembled and used for the foundation pit enclosure wall. The foundation pit enclosure wall comprises a plurality of pieces of wall shape steel which are sequentially distributed in the length direction of the foundation pit enclosure wall, in addition, the upper end of the wall shape steel extends out of the ground, the assembled crown beam structure comprises a plurality of steel beam components in one to one correspondence with the wall shape steel, the steel beam components are positioned above the ground, the steel beam components comprise two steel beam single bodies which are arranged on the wall shape steel in a tight holding manner, two adjacent steel beam components are integrally connected through a steel beam connecting part, and the steel beam component is connected with the steel beam connecting part through bolts.

Description

technical field [0001] The invention relates to the field of retaining walls of foundation pits, in particular to an assembled crown and beam structure for retaining walls of foundation pits. Background technique [0002] For the basement pit of a building or structure, it is often necessary to construct a retaining wall to seal the groundwater from the outside of the pit, and at the same time, it also has the active earth pressure outside the retaining pit. The current retaining wall of foundation pit usually adopts TRD construction method, SMW construction method, etc. The retaining wall of foundation pit includes a number of wall profile steel distributed sequentially along the length direction of foundation pit retaining wall, and the upper end of the wall profile steel protrudes above the ground surface Then, construct the reinforced concrete capping beam (or called the reinforced concrete crown beam) along the length direction of the underground cement-soil wall on the...
