Abstract

The invention discloses an underground diaphragm wall steel bar cage structure and a construction method thereof. The underground diaphragm wall steel bar cage structure comprises a plurality of steel bar cage units (1) and a plurality of connecting structures (21) from bottom to top. The steel bar cage units (1) are connected through the connecting structures (21). Each of the connecting structures (21) comprises two connecting steel plates (2) and two connecting clamp plates (3). The connecting steel plates (2) are respectively welded to the connecting end among the steel bar cage units (1). The connecting clamp plates (3) are located on two sides of each of planes of the connecting steel plates (2), and the connecting clamp plates (3) are fixedly connected with the connecting steel plates (2). The hoisting efficiency and safety of a steel bar cage are improved, the using amount of transverse reinforced trusses is decreased, and the steel bar cage structure is reasonable in structure, reliable in connection and excellent in structural performance.

Description

technical field [0001] The invention relates to the field of design and construction of an underground diaphragm wall in building foundation pit engineering, in particular to an underground diaphragm wall reinforcement cage structure and a construction method thereof. Background technique [0002] Due to its high rigidity, the underground diaphragm wall has the advantage of having little impact on the soil and structures around the foundation pit, and can be used as a retaining wall and the basement exterior wall of the main structure. The construction steps of the cast-in-place underground diaphragm wall in the trough section can be divided into guide wall construction, steel cage making, mud making, trough setting out, trough forming construction, hanging and placing the steel cage, underwater concrete pouring, and trough section joint treatment, etc. According to the particularity of functional requirements and geological conditions, the manufacture and hoisting of the re...
