Tunnel segment mounting mechanism and mounting method thereof

Abstract

The invention discloses a tunnel segment mounting mechanism and a mounting method thereof. The mounting mechanism comprises symmetrically-distributed supporting assemblies, each supporting assembly comprises side plates, symmetrically-distributed mounting columns are arranged below the side plates, lifting columns are arranged in the mounting columns, a second hydraulic rod is arranged between the side plates, side face supporting assemblies are arranged at the two ends of the second hydraulic rod, a top supporting assembly is arranged above the side plates, a moving assembly is arranged on one side of the side plates and comprises a movable frame, a rotating disc is arranged on the movable frame, a mounting assembly is arranged on the rotating disc and comprises a second movable plate, and limiting assemblies which are symmetrically distributed are arranged on the second movable plate. The mounting mechanism is provided with a tunnel segment supporting structure capable of automatically moving, the angle, the height and the radius can be adjusted according to actual use scenes, the safety of tunnel segment mounting is greatly improved, positioning is accurate and fixing performance is good when the tunnel segments are mounted, the tunnel segments are prevented from falling off and shaking during rotating mounting, the inclined lifting design is adopted, and the mounting space is saved.

Description

technical field [0001] The invention relates to the technical field of tunnel segments, in particular to a tunnel segment installation mechanism and an installation method thereof. Background technique [0002] Tunnel segment, also known as shield segment, is the main assembly component of shield construction and the innermost barrier of the tunnel, which bears the role of resisting soil pressure, groundwater pressure and some special loads. The tunnel segment is the permanent lining structure of the shield tunnel, the quality of the tunnel segment is directly related to the overall quality and safety of the tunnel, and affects the waterproof performance and durability of the tunnel. The production of tunnel segments usually uses high-strength impermeable concrete to ensure reliable load-bearing and waterproof performance. The production mainly uses the finished segment mold to form after sealing and pouring concrete. When the tunnel segment is installed, after the ring seg...

AI Technical Summary

Problems solved by technology

When the tunnel segment is installed, after the ring segment is assembled, use the shield jack to apply pressure evenly and fully tighten the axial connecting bolts. After the shield continues to excavate, the earth (water) pressure will The lining will be deformed under the action of the lining, and the fastened connecting bolts will be loose during assembly. Use a torque wrench to tighten the connecting bolts again. Before tightening the connecting bolts, the front row of tunnel segments may fall due to loose screws. Cause engineering accidents and damage the personal safety of construction workers
