A multifunctional trestle suitable for tunnel inverted arch construction and its method

Abstract

The invention discloses a multifunctional trestle suitable for tunnel inverted arch construction and a method. The problems that in the prior art, the tunnel inverted arch construction speed is low, and the worker construction safety coefficient is low are solved. Through the setting of the scheme, simultaneous operation of multiple operation machines in a tunnel can be achieved at the same time, the tunnel working efficiency is effectively improved, and vehicle passing is reasonably arranged. According to the specific scheme, the multifunctional trestle suitable for tunnel inverted arch construction comprises at least two passing rails, the passing rails are used for passing of the operation machines, the passing rails are arranged on supporting columns with set height, approach bridges are arranged on the two sides of each passing rail respectively, and therefore the operation machines can conveniently enter the passing rails through the approach bridges. Distance setting is set between the adjacent passing rails at intervals, side wing plates are arranged on the side faces of the passing rails, the side wing plates are provided with entrances and exits used for allowing people to come in and go out, and people can conveniently work below the passing rails through the arrangement of the entrances and the exits.

Description

technical field [0001] The invention relates to tunnel construction engineering, in particular to a multifunctional trestle and method suitable for tunnel inverted arch construction. Background technique [0002] With the continuous development of my country's economy, more and more tunnels under different geological conditions have appeared. High-quality and multi-functional construction machinery is particularly important for the efficiency and safety of tunnel construction. [0003] The inverted arch is an important part of the lining structure in tunnel construction, and its follow-up timing has an important impact on the stability of the tunnel. Safe inverted arch construction is not only a guarantee for the safety of the construction personnel, but also particularly important for the overall safety of the tunnel . Therefore, determining a reasonable inverted arch construction machine can not only speed up the construction progress, but also benefit the safe constructi...

AI Technical Summary

Problems solved by technology

[0004] In order to cross the obstacle section in the tunnel, it is necessary to use an inverted trestle bridge. To use the trestle bridge during inverted arch construction, the first problem is that during the construction process, the operating machinery includes shotcrete vehicles, slag removal vehicles, loaders and other machinery, and these machinery are running The process will be affected by the construction process of this section, which will affect the smooth passage of vehicles

At present, during the construction of the inverted arch, the workers are constructing under the trestle, and the two ends of the trestle are leaking, which seriously threatens the safety of the construction personnel under the trestle; when the inverted arch is filled, the concrete tanker lays concrete on the trestle, occupying the trestle track, and other vehicles Impassable, which in turn affects the working time of the entire tunnel inverted arch, which is not conducive to the quality of tunnel forming
