Secondary lining trolley backform mounting device and constructing method thereof

Abstract

The invention relates to a secondary lining trolley backform mounting device. The secondary lining trolley backform mounting device comprises chute groups, a guide rail device, a guide rail moving mechanism, a jacking device and a transferring device; the chute groups are mounted on upright posts of a trolley gantry and is provided with space for the guide rail device to slide longitudinally; theguide rail device can move along the chute groups under the action of the guide rail moving mechanism; the jacking device is mounted on a longitudinal beam at the bottom of the gantry and is used forjacking a backform to a transfer height; and the transferring device can move along the guide rail device and can ascend and descend, and is used for transferring and moving the backform to a mountingposition, and placing the backform on a platform beam. The invention also provides a construction method applied to the device. The secondary lining trolley top die mounting device can realize the mounting of the backform of a secondary lining trolley, and is easy to operate and safe and reliable.

Description

technical field [0001] The invention relates to the field of tunnel construction equipment, in particular to a two-liner roof form installation device and a construction method applied to the device. Background technique [0002] At present, the second lining trolley of the tunnel is generally installed in the tunnel hole. Due to the limitation of the space in the hole, it is usually assembled by a loader supplemented by a manual hoist. The assembly process is: assembly preparation→determination of the lifting point position→the location of the vault lifting point Elevation and excavation → installation of anchor bolts → site leveling in the cave → laying trolley track → installation of running mechanism → installation of bottom longitudinal beam → installation of door frame → installation of scissors brace → installation of platform beam → installation of bracket → installation of roof Mold→Install side mold→Install side mold→Install hydraulic system→Complete machine debugg...

AI Technical Summary

Problems solved by technology

[0004] 1. It is necessary to increase the height of the vault at the lifting point and expand the excavation, which increases the amount of work and construction difficulty;

[0005] 2. Use the pre-embedded anchor rod as the lifting point, and use the wire rope to lift the four corners, which has poor maneuverability and potential safety hazards;

[0006] 3. Due to the limitation of the bearing capacity of the pre-embedded anchor, it is necessary to install the bracket and the top form separately. Install the bracket first and then install the top form. Whe
