AI Technical Summary

Technical Problem

The existing excavation support method cannot be centrally supported, the support time is long and the efficiency is low, which is not conducive to the development of tunnel excavation technology.

Method used

A temporary hydraulic support device for head-on excavation is designed, adopting an integral frame structure, including support beams, cross beams, columns, lifting cylinders, push cylinders, slide rails and support wheels. Through the synergy between lifting the oil cylinder and thrusting the oil cylinder, the gradual forward movement and support of the support beam and cross beam are achieved.

Benefits of technology

The support has been gradually improved, the labor intensity has been reduced, the support operations have been completed in a concentrated manner, the excavation efficiency and the safety of support operations have been improved, and the development of tunnel excavation technology has been promoted.

Abstract

The invention relates to a temporary hydraulic supporting device for a tunneling head-on and a supporting method of the temporary hydraulic supporting device. The supporting device adopts an integral frame structure, supporting stand columns are distributed in a left-right corresponding mode, supporting beams are arranged in a staggered mode, a cross beam is fixedly connected with one supporting beam of each group of supporting beams, and the lower portions of the stand columns penetrate through sliding rails and are connected with the sliding rails in a sliding mode. From the back, the pushing oil cylinders extend out in sequence, so that the stand columns, the supporting beams connected with the stand columns and the cross beams move forwards in sequence, and the supporting effect is achieved. When all the pushing oil cylinders stretch out, the pushing oil cylinders are sequentially recovered from the back, the stand columns, the supporting beam connected with the stand columns and the cross beam are sequentially moved forwards, and when all the pushing oil cylinders retract, one circulation action is completed. Supporting is performed step by step, the labor intensity is relieved, centralized supporting operation is achieved, the tunneling efficiency and the safety of supporting operation are improved, and development of the roadway tunneling technology is facilitated.
