AI Technical Summary

Technical Problem

The existing water conservancy project tunnel vault support device has time consumption and collapse risks during welding and concrete solidification, and the support capacity is insufficient in the early stage.

Method used

A vault support device including a hoisting assembly, an adjustment assembly and a support connecting assembly is designed. Through the combination of the support pipe and the arcuate support plate, the adjustment and abutment of the arcuate connecting plate and the arcuate support plate are achieved by using the hoisting drive mechanism and the adjustment assembly to achieve adjustment and abutment of the arcuate connecting plate and the arcuate support plate, thereby increasing the support area and protection area.

Benefits of technology

It improves the support effect and safety of the tunnel vault, reduces construction time and risks, and ensures the stability and service life of the tunnel during the reinforcement process.

Abstract

The invention belongs to the technical field of tunnel vault supporting, and particularly relates to a vault supporting device for reinforcing a hydraulic engineering tunnel. Comprising two supporting mechanisms symmetrically arranged along the radian of a tunnel. The supporting mechanism comprises a jacking assembly, an adjusting assembly and a bearing connecting assembly. The jacking assembly comprises a supporting pipe and an arc-shaped supporting plate. The two ends of the arc-shaped supporting plate are slidably connected with a rectangular connecting plate and an arc-shaped connecting plate. The rotating angles of the arc-shaped connecting plate and the arc-shaped supporting plate are controlled through the supporting pipe, so that adjustment is carried out according to the radian of the tunnel vault, the arc-shaped connecting plate and the arc-shaped supporting plate are attached, and the supporting effect is improved; the rectangular connecting plate is controlled to extend out through the bearing connecting assembly, so that top sealing is facilitated; and the rectangular connecting blocks on the two sides are connected, so that the middle part is prevented from being broken due to overlarge weight, and the connecting effect is improved.
