Description

An arch installation device for repairing tunnel defects in operation

technical field

The invention relates to the field of tunnel arch installation equipment, and more specifically relates to an arch installation device for repairing tunnel defects in operation.

Background technique

With the continuous increase of the total mileage of railway tunnels in my country, the diseases of railway tunnels in operation are becoming more and more frequent, such as tunnel lining structure cracking, block loss, network cracking, water leakage, frost heaving and other diseases, which have seriously threatened the safety of train operation .

Aiming at the problem of tunnel structural diseases, the public works department often uses simple scaffolding and machinery for maintenance. Among them, the installation of arches is the most critical and time-consuming process. Currently, manual and simple hoisting tools and scaffolding are used for hoisting and splicing of arches. Not only the construction safety cannot be guaranteed, but also the labor intensity is high, the construction efficiency is low, the construction quality is not high, the construction progress is slow and the safety factor is low.

At present, in this technical field, in order to improve the efficiency of arch installation, tunnel arch trolleys are often used for installation, which basically realizes semi-mechanization and greatly reduces the labor intensity of operators. The existing tunnel arch installation structure uses manipulators or other cranes The tool grabs the arch frame from the ground, and then closes the gripper to lift the arch frame into place. However, the existing tunnel arch installation equipment is designed for the tunnel construction stage, and does not take into account the arch installation conditions in the repair of tunnel defects in operation. Due to the nature of operating tunnels, there are many construction restrictions on repairing the defects of existing tunnels. It mainly includes the following restrictions:

1) The working time is short, and it can only work during the tunnel operation skylight time (4-6h). After deducting the time for going on and off the assembly line and construction preparation, the actual working time is less than 4 hours. Currently, the tunnel is being repaired due to no suitable The machine tool still adopts the operation mode of manual work and simple tooling as the supplement. The installation of the arch frame with 1.2m bushing takes 7 skylights and more than 10 people to work. Therefore, higher requirements are placed on operating efficiency

2) Existing building restrictions for tunnels. According to the requirements of national standards, planning and electrification, catenaries are generally arranged on the top of currently operating tunnels, and lighting lines, special cables and public network cables are arranged on both sides of the tunnel, and due to force requirements, contact The contact wires on the net suspension are arranged in a zigzag shape, and they need to be avoided during construction, otherwise there is a risk of electric shock and damage to the wires when the equipment and personnel are working.

3) Transportation restrictions. According to existing regulations and system requirements, maintenance equipment and machinery can only be transported by railway locomotives that meet the requirements, and the maintenance equipment and machinery carried on the locomotive must meet GB1.46.1-2020 "Standard Gauge Railway Gauge Part 1: Rolling Stock Gauge requires that the transportation limit shall not be exceeded.

Therefore, under the above-mentioned restrictive conditions, how to improve the efficiency and quality of arch installation during the repair of tunnel defects in operation, reduce labor intensity, and at the same time, ensure the safety of construction, and solve the problems of transportation, contact wire avoidance, and automatic installation, is currently an issue in this field. Problems that technicians need to solve urgently.
