Description

A highway tunnel prefabricated assembly corrugated steel lining structure assembly platform

technical field

The invention relates to the field of lining structure construction of highway tunnels under construction, in particular to a highway tunnel prefabricated assembling corrugated steel lining structure assembling platform.

Background technique

During the construction of highway tunnels in weak areas, it is necessary to improve the strength and construction efficiency of the lining, especially in the engineering section prone to rock bursts and other disasters, it is necessary to expand the support surface, improve the early strength, and shorten the construction time of the lining support. The prefabricated assembled corrugated steel pipe sheet lining structure, which has been widely used abroad, has been applied in China. It has the advantages of large supporting area and high early strength, and has achieved good engineering results.

At present, prefabricated corrugated steel lining structures are mainly assembled by crane hoisting, manual assembly, and trolley lifting. Among them, when the crane is hoisted, it is necessary to manually adjust the posture of the segment before it can be connected to the designated position, and the crane is only suitable for open-cut tunnel construction; the efficiency of manual assembly of corrugated steel pipe is low, and the quality of the current standard corrugated steel pipe can reach 500kg, it is extremely inconvenient to lift and install. When the construction equipment such as the arch installation trolley is used for lifting, it occupies the construction channel in the tunnel, and a special construction platform is required to facilitate the manual installation of the segment joints.

For ordinary tunnel construction platforms, the existing Chinese utility model patent with application number 201720384226.5 discloses a tunnel construction platform, the construction platform is a three-layer gantry structure, and each working platform is provided with straight guide rails, which are slidably matched with them. The sliding block, the manned flat plate and the steel protective plate; the middle part of the gantry bracket is provided with a loading platform, a water storage tank and an exhaust fan, and an ice cube storage bin is arranged inside the water storage tank. However, the platform is designed for construction workers, and each platform plate cannot be moved, which cannot meet the operation requirements of the manipulator with limited working radius. In addition, the fixed platform plate will also make construction difficult in the tunnel area near the plane where the platform plate is located, resulting in construction dead ends. Therefore, the construction platform cannot carry large-scale construction equipment such as robotic arms for segment assembly.

The existing Chinese invention patent with the application number of 201911322163.0 discloses a tunnel construction platform that is easy to move. The platform is a single-layer construction platform. The bidirectional screw rod is driven by a motor to support the support plate and the arc plate, and the arc plate is used to withstand On the top of the tunnel, the roof is used to support the top of the tunnel to prevent the falling rocks from the top of the tunnel from hurting workers and form a safe working space. The construction platform in this patent is a manually designed construction platform, and it is a single-layer platform, not for carrying The reserved space for construction machinery is not suitable for the assembly of corrugated steel pipe sheets.

To sum up, there are few prefabricated and assembled construction platforms for existing highway tunnels, and the existing construction platforms have some major shortcomings, which are summarized as follows:

(1) The reserved construction channel at the bottom is narrow, and the material transportation near the face is restricted.

(2) The platform slab is inactive, which will easily cause construction difficulties in the tunnel area near the platform slab plane.

(3) There is no installation space reserved for construction equipment, and the section of structural components is small and difficult to bear the load of construction equipment, and mechanized construction has not yet been realized.
