A Synchronous Construction Method for Reinforced Concrete with Supporting Beams and Floor Slabs in Deep Foundation Pit

Abstract

The invention discloses a deep foundation pit inner support beam and floor wood mold reinforced concrete synchronous construction method. The soil excavation quantity on the inner sides of inner support beams is effectively reduced by adopting a temporary retaining wall scheme of profile steel and steel plates; the inner support beams adopt non-brickwork adobe diaphragms; wood mold plates are mounted on the beam sides; cushion layers and isolation layers are constructed on the soil surfaces of the beam bottoms and the plate bottoms; the beam plate concrete once synchronous casting is realized;the mold plates mounted on the beam sides are reinforced by adopting a beam inner side reinforcing mold; bolts with rings at one ends, flower basket screw rods and reinforcement pull hooks with benthooks at the two ends are used for tensioning inner side screw rods from the inner sides of the mold plates to fix the mold plates on the beam sides; and the profile steel is used for preventing deformation of the mold plates during concrete casting.

Description

technical field [0001] The invention relates to the field of deep foundation pit support construction, in particular to a synchronous construction method for reinforcing concrete with supporting beams and floor slab wooden molds in deep foundation pits. Background technique [0002] As the foundation pit of the project basement is getting deeper and more and more buildings are around the project, the construction site of the project is becoming more and more limited. In order to organize on-site traffic and arrange temporary material storage yards, more and more internal support beams and floor slabs are used in the support design of internal support foundation pits. Due to the synchronous construction of inner support beams and slabs in the inner support construction, there is a certain degree of difficulty in the case of not laying brick membranes. The conventional method is to pour the beam and slab separately twice, first pour the concrete of the beam below the bottom o...
