By adopting the technical scheme, the overlapping length meets the requirement of construction specifications, so that the post-cast strip and the original structural wall form a whole.

Optionally, the thickness of the water stop steel plate is 3 mm.

Through adopting above-mentioned technical scheme, the stagnant water steel sheet of 3mm thickness can play good stagnant water effect.

In summary, the present application includes at least one of the following beneficial technical effects:

1. the combination degree of the concrete of the post-cast strip and the original structural wall is improved by arranging the lead wire mesh on the original structural wall surface, and the shooting hooks are arranged on the lead wire mesh and anchored into the post-cast strip, so that the combination degree of the post-cast strip and the original structural wall is further improved;

2. by using the compensation shrinkage concrete for pouring the post-pouring belt, the tensile strength of the compensation shrinkage concrete can resist the shrinkage stress, so that the compensation shrinkage concrete does not crack during the drying shrinkage.

Detailed Description

The present application is described in further detail below with reference to figures 1-2.

The embodiment of the application discloses a structure of a post-cast strip of a reinforced retaining wall. Referring to fig. 1, the reinforced retaining wall post-cast strip structure comprises a post-cast strip 1, original structure walls 3 located on two sides of the post-cast strip 1, and a lead wire mesh 2 installed on one opposite side of the original structure walls 3.

Horizontal distribution reinforcing bars 4 in the original structure wall 3 that is arranged in post-cast strip 1 both sides stretch out original structure wall 3 respectively, and the overlap joint between two relative horizontal distribution reinforcing bars 4, overlap joint length are 1.6La, satisfy the requirement to overlap joint length in the construction specification.

In original structure wall 3 pre-buried have stagnant water steel sheet 5, stagnant water steel sheet 5 thickness is 3mm, and the width is 300mm, stagnant water steel sheet 5's vertical setting, half imbed in original structure wall 3, outside half is located original structure wall 3, stagnant water steel sheet 5 plays water-proof effects, prevents that water from permeating the structure main part from construction joint department.

Install the lead wire net 2 on two relative one sides of original structure wall 3, the lead wire net 2 can increase the concrete in the post-cast strip 1 and original structure wall 3 between the degree of combining, makes the difficult fracture of the junction of post-cast strip 1 and original structure wall 3.

Referring to fig. 1 and 2, a shooting hook 21 is mounted on a lead screen 2, the shooting hook 21 is made of a metal material and comprises a hook rod 211, a hook claw 212 is integrally formed at one end of the hook rod 211, the hook claw 212 is a double-claw hook, a tail ring 213 is integrally formed at one end of the hook rod 211, which is far away from the hook claw 212, the tail ring 213 is annular, an opening is formed at one end of the tail ring 213, which is far away from the hook rod 211, and the tail ring 213 has certain elasticity; the opening of the tail ring 213 is opened by force, then the tail ring is clamped into the lead wire mesh 2 and then released, the opening of the tail ring 213 is closed, and thus the shooting hook 21 is installed on the lead wire mesh 2; the shooting hook 21 can increase the combination degree of the concrete and the lead wire mesh 2 in the post-cast strip 1, so that the combination degree between the post-cast strip 1 and the original structural wall 3 is further increased.
