Jacking force transmission device for pipe-jacking construction

Abstract

The present invention relates to the technical field of pipe-jacking construction, and in particular to a jacking force transmission device for pipe-jacking construction. Support frames, crossbars and steel columns are include, the support frames and the crossbars are welded vertically, the steel columns are connected to the support frames through the crossbars, abutting disks are arranged on surfaces of the steel columns, sliding rods are disposed on surfaces of the abutting disks; sliding grooves are disposed inside the steel columns, and control grooves are disposed on inner sides of the sliding grooves; and regulating rods are inserted on surfaces of the steel columns, abutting blocks are fixedly connected to bottom ends of the regulating rods, and screw holes are disposed on outside surfaces of the steel columns. In the present invention, through the connection of the support frames and the crossbars, the support effect on placement of the steel column are realized under the action of the crossbars, and under abutting the steel columns against the wall, and on the premise of sufficient stability, the transmission of jacking counterforce is satisfied in the process of pushing pipe-jacking, well solving the problem that the middle part of the station cannot provide stable facilities for the jacking counterforce.
