AI Technical Summary

Technical Problem

Existing tunnel construction support devices lack flexibility during support, making it difficult to adapt to different cross-sectional shapes and sizes. They also lack lateral stability and deformation monitoring mechanisms, resulting in high safety risks.

Method used

A tunnel construction support device was designed, comprising a column, a top rod, a support rod, an adjustment mechanism, and a side support mechanism. The height of the top support is adjusted by the adjustment mechanism, the side support mechanism supports the tunnel sidewall, and deformation is monitored by a scale, thus achieving flexible support and timely response.

Benefits of technology

It improved the safety of tunnel construction, reduced injuries to construction workers from falling rocks from the top and side walls, enhanced the stability and deformation monitoring capabilities of the equipment, and ensured the safety of the construction process.

Abstract

The invention relates to the technical field of construction supporting equipment, and discloses a tunnel construction supporting device which comprises two stand columns, a top rod is fixedly connected to the tops of the stand columns, the two stand columns and the top rod form a door-shaped supporting frame, a supporting rod is fixedly connected to the positions, located below the top rod, of the inner sides of the stand columns, and the supporting rod is fixedly connected to the top of the stand columns. The tunnel construction supporting device comprises a supporting rod, a top rod is arranged on the supporting rod, a top supporting mechanism is arranged on the upper surface of the top rod, and an adjusting mechanism is arranged in the middle of the supporting rod and used for adjusting the height of the top supporting mechanism. The height of the top supporting mechanism can be adjusted through the adjusting mechanism, so that the top supporting mechanism supports the top of the tunnel to prevent falling stones on the top of the tunnel from hitting constructors to cause injury, and the graduated scale arranged on the stand column is matched, so that the constructors can quickly know the change when the change occurs so as to timely deal with the change.
