Fixing piece is equipped on the inside of lower diaphragm wall between vertical reinforcement, the profiled sheet is connect with fixing piece, the fixing piece and underground
The steel reinforcement cage of diaphragm wall is welded and fixed.Due to being equipped with profiled sheet on the inside of diaphram wall, so that underground structure inwall and ground
Lower diaphragm wall forms whole force structure component, while waterproof unit of the profiled sheet as underground structure inwall.
Diaphram wall needs to excavate a long and narrow deep trouth on the ground when building, and then hangs steel reinforcement cage, but
During hanging steel reinforcement cage, steel reinforcement cage is in vacant state, and steel reinforcement cage is easy to happen lateral movement, thus steel reinforcement cage be easy and
The side wall of deep trouth collides, and the side wall of deep trouth is caused to collapse, and influences the intensity of low diaphragm wall.
Utility model content
In view of the deficienciess of the prior art, the purpose of this utility model is to provide a kind of construction of diaphragm wall knots
Structure can be defined the movement of steel reinforcement cage, and then can prevent steel reinforcement cage and depth by the guide post being set in deep trouth
The side wall of slot collides, and is unaffected the intensity of low diaphragm wall.
To achieve the above object, the utility model provides following technical solution: a kind of construction of diaphragm wall structure, packet
It includes to be set on deep trouth two sidewalls and leads wall and multiple steel reinforcement cages in deep trouth, further include multiple guiding in deep trouth
Column, guide post are set in deep trouth vertically, and guide post is uniformly bonded with the two sidewalls of deep trouth；
Open up fluted on steel reinforcement cage, groove can be bonded with the outer circumference surface of guide post.
The groove on steel reinforcement cage is covered in guide post when steel reinforcement cage is installed by using above-mentioned technical proposal, it can be right
The decline of steel reinforcement cage is oriented to, and is made steel reinforcement cage be merely able to move along vertical direction, lateral movement will not be occurred, in turn
Steel reinforcement cage is set not collide with the side wall of deep trouth, therefore the side wall of deep trouth will not collapse, and make the intensity of low diaphragm wall
It is unaffected.
The utility model is further arranged to: it is fixedly connected with convex block on the side wall for leading wall and guide post fitting, and
Convex block is symmetrical arranged, and the arc groove that can be bonded with guide post outer circumference surface is offered on convex block.
