Abstract

The invention discloses an underground diaphragm wall tenon-and-mortise type reinforcement cage connecting structure which comprises underground diaphragm walls, a tenon-and-mortise type connecting frame, a dovetail groove, a dovetail joint, a coupler female head, a coupler male head, penetrating steel shafts and a shaft clamping device clamp. The two underground diaphragm walls are connected through the tenon-and-mortise type connecting frame, concrete is poured on the tenon-and-mortise type connecting frame in a layered mode, and the underground diaphragm walls and the tenon-and-mortise type connecting frame are connected into a whole. Main bodies of reinforcing steel bars reserved at the wall body are fixed by a reinforcement cage in a plug-in manner, and multiple groups of parallel penetrating steel shafts are used for fastening, so that the quality unevenness caused by welding and fixing and the complicated process of quality inspection and checking are reduced; and the technical requirements of green construction, civilized construction and fabricated construction are met. The assembly type structure is simple in process, the assembly period is short, and a large amount of manpower and time expenditure on site are saved.

Description

technical field

[0001] The invention belongs to the technical field of building construction, and in particular relates to a connection method of a steel bar skeleton of a ground connection wall based on a mortise and tenon connection structure. Background technique

[0002] The underground diaphragm wall structure is a kind of trenching machine used on the ground for basic engineering, mainly as a water interception, anti-seepage, load-bearing, and water-retaining structure. As the first construction link of deep foundation pit engineering, the underground diaphragm wall structure is also the most important link. It plays an important role in stabilizing the ground and ensuring the safety of the internal structure of deep foundation pit engineering.

[0003] The steel cage is the main frame structure of the wall, and it is generally hoisted by a crane during the construction process; during the hoisting and splicing, the standardized production of the connection joints, as ...
