Abstract

The invention discloses a pipe-jacking construction device, which belongs to the technical field of tunnel construction. The device comprises a tunnel side portal ring structure, a shaft side portal ring structure and an elastic ring-shaped sealed inner tube. The inner wall of the tunnel side portal ring structure and the shaft side portal ring structure are provided with ring-shaped sealed inner tubes. Valve structures are disposed outside the tunnel side portal ring structure and the shaft side portal ring structure. The valve structure is connected with the corresponding ring-shaped sealed inner tube and is capable of filling the preset filler into the corresponding ring-shaped sealed inner tube. The device is capable of filling the preset filler into the elastic ring-shaped sealed inner, so that the elastic ring-shaped sealed inner expands and produces static friction force on the pipe joint, which enhances a stopping effect on the pipe joint.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a pipe jacking construction device. Background technique [0002] In the technical field of tunnel construction, pipe jacking construction is often involved. The pipe jacking construction mainly uses the thrust of the main jacking cylinder to overcome the friction between the pipe joint and the surrounding soil, and push the pipe joint into the tunnel from the tunnel door. The inner preset position, and finally return the main top oil cylinder. [0003] During the pipe jacking construction process, it is necessary to seal the tunnel door and prevent the pipe joint from retreating during the retraction of the main jacking cylinder. Currently, the usual figure 1 The shown pipe jacking construction device is used to seal the portal and stop the pipe joint from retreating. The device includes a portal fixed ring plate 01, a portal ring structure 02, a cord rubber ring 0...
