Self-propelled tunnel lining dismantling equipment and using method

Abstract

The invention relates to equipment for dismantling a tunnel lining, in particular to self-propelled tunnel lining dismantling equipment and a using method. The self-propelled tunnel lining dismantlingequipment comprises a dismantling system, a walking system, a power system and a control system. The dismantling system is used for dividing the to-be-replaced lining of a tunnel into a plurality ofdismantling units separated from a tunnel main body; the walking system is used for conveying the dismantling system to an operation area corresponding to the to-be-replaced lining of the tunnel; thepower system is used for providing power for the dismantling system and the walking system to complete actions; and the control system sends action instructions to the dismantling system, the walkingsystem and the power system. Compared with the prior art, the self-propelled tunnel lining dismantling equipment and the using method have the beneficial effects that protection, cutting and dismantling are realized during tunnel lining replacement, disturbances of lining dismantling to surrounding rock and existing linings are reduced, frequent equipment replacement is not required during construction, the construction safety is guaranteed, the operation efficiency is improved, and the organization difficulty is reduced.

Description

technical field [0001] The invention relates to a tunnel lining removal device, in particular to a self-propelled tunnel lining removal device and a usage method. Background technique [0002] With the continuous development of transportation infrastructure, the scale of tunnel construction is increasing day by day. However, affected by environmental conditions, construction quality and other factors, the problem of tunnel lining disease gradually appears, and some cracked and severely corroded linings need to be replaced. At present, lining removal lacks a mature theoretical system, perfect technical scheme, and professional construction equipment, which can easily lead to risky accidents such as structural instability and tunnel collapse. The existing lining removal methods mainly include manual chisel removal, blasting removal, silent crushing and mechanical removal. The main shortcomings and improvement measures are as follows: [0003] (1) Manual chiseling - workers ho...

AI Technical Summary

Problems solved by technology

[0004] Main disadvantages: workers stand on the platform for construction, and there is a risk of high-altitude operations; workers have been in a dusty and noisy environment for a long time, and their health is seriously threatened; after partial removal of the lining, there is a risk of collapse of the working surface, which endangers personal safety; Hand-held portable equipment is very inefficient, the bench accommodates workers limited, and the lining removal efficiency is very low

[0006] Main disadvantages: blasting demolition has high requirements on the stability of surrounding rock and structure, and is mainly used in large-scale continuous operations, so the scope of application of this method has certain limitations; blasting vibration strongly disturbs surrounding rock and existing lining, and demolition The boundary is difficult to control; the blasting effect is controlled by complex factors, and the demolition quality is difficult to guarantee

[0008] Main disadvantages: the controllability of the reaction time of the silent breaking agent is poor. When the lining of the arch wall is broken, the space under it is strictly prohibited from passing by people and vehicles. The construction organization is difficult, the potential risk is high, and the operation efficiency is low; the crushing effect is controlled by many factors, and the degree of crushing is difficult to control

[0010] Main disadvantages: the cutting machine and the breaking hammer are two independent equipments, which need to be replaced frequently during construction, which makes the organization difficult and the work efficiency is low; the process requirements are strict, and there is a risk of collapse of the working surface during partial cutting or breaking; cutting Machines are mostly modified from other equipment, with low reliability and poor professionalism
