Benefits of technology

[0015] 1. A through hole is made in the retaining wall to accommodate the PVC pipe and horizontal reinforcing bars. The PVC pipe protects and guides the horizontal reinforcing bars, preventing them from shifting during concrete pouring and ensuring accurate bar placement. A torque wrench is used to rotate the threaded sleeve, and the connecting reinforcing bars are installed inside the sleeve via threaded connection, achieving an efficient and stable connection. This avoids the potential for weak connections that may occur with traditional welding or binding methods. When the other end of the threaded sleeve is not immediately used for connecting reinforcing bars, a cap is installed at the end of the sleeve furthest from the horizontal reinforcing bars to seal the sleeve and prevent concrete from entering and affecting the subsequent installation of the horizontal reinforcing bars.

Abstract

The application relates to the field of underground continuous wall construction in civil engineering, and discloses a rectangular pile inter-pile steel bar connecting structure which comprises a retaining wall, a first-excavated pile and a neighboring pile which are arranged on the left and right sides of the retaining wall respectively, a plurality of holes which are arranged on the retaining wall in a penetrating mode, a PVC pipe which is arranged in the hole, a horizontal steel bar which is arranged in the PVC pipe, and two straight thread sleeves. The application realizes efficient and stable connection of the connecting steel bar, avoids the problem of unstable connection which may exist in the traditional welding or binding mode, when the other end of the straight thread sleeve is temporarily not provided with the connecting steel bar, a plug cap is arranged at the end of the straight thread sleeve which is far away from the horizontal steel bar, the plug cap is used for closing the sleeve and preventing the concrete from being poured into the straight thread sleeve, so that the subsequent installation and assembly of the horizontal steel bar are not affected, the connecting steel bar and the steel bar cage are tightly connected, the wall body connection is strengthened, the overall rigidity of the supporting system is improved, the deformation of surrounding structures is reduced, and the project cost is saved.
