Abstract

The invention discloses an assembled all-steel crown beam for a foundation pit enclosure wall; and the assembled all-steel crown beam for the foundation pit enclosure wall can guarantee overall intensity of the foundation pit enclosure wall, is short in construction period and convenient to construct and dismount, and can be recycled. The foundation pit enclosure wall comprises multiple wall bodyprofile steel distributed in the length direction of the foundation pit enclosure wall in sequence; and the upper end of the wall body profile steel extends above the ground surface. The assembled all-steel crown beam for the foundation pit enclosure wall comprises multiple steel beam monomers connected in sequence; two adjacent steel beam monomers are connected through bolts; the steel beam monomers are provided with multiple vertical mounting grooves matched with the wall body profile steel; the steel beam monomers are positioned above an underground cement soil wall; and the wall body profile steel is inserted in the corresponding vertical mounting grooves, so that the upper ends of the wall body profile steel of the foundation pit enclosure wall are connected as a whole through the steel beam monomers connected in sequence.

Description

technical field [0001] The invention relates to the construction field of foundation pit enclosure walls, in particular to an assembled all-steel crown beam for foundation pit enclosure walls. 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 th...
