Problems solved by technology

In addition, in the above-mentioned existing construction methods, each trench formwork needs to be installed manually, and the installation quality is difficult to control, and the formwork installation is not firm enough, which is prone to formwork run-out; the lack of sealing between the formworks will affect the solid concrete. linear

Abstract

The invention relates to a forming device for a tunnel center gutter and side ditches and a forming process thereof. A used mold board is an integral type groove mold board with a complete groove shape, the forming device comprises a traveling device for driving the device to move in a tunnel, and a plurality of telescopic mechanisms are used for controlling the mold board to perform automatic installation and disassembly; and the process adopting the device to pour can simultaneously perform symmetrical pouring on the side ditches on the two sides of the tunnel, and the center gutter is also symmetrically poured from the two sides of the tunnel. According to the device and the process thereof, the tunnel center gutter and the side ditches can be poured and formed once, so that the construction workload is reduced, the mold board can be automatically installed and disassembled, the problems caused by manual installation and disassembly of the mold board can be avoided, and the construction efficiency can be improved; and when concrete is poured, symmetrical pouring is adopted, and deviation on the two sides of a table frame can be avoided.

Description

technical field [0001] The invention relates to equipment and technology for forming grooves in tunnel construction. Background technique [0002] In the construction of tunnel engineering, it is necessary to set up special trenches for arranging lines, equipment and drainage. These trenches usually include a central gutter located in the center of the tunnel, and side ditches on the left and right sides of the tunnel. At present, the central ditch and side ditch of the tunnel are poured separately, and the left and right ditch and the central ditch need to be constructed three times separately, which involves many operating procedures, high labor intensity and low efficiency. In addition, in order to meet the traffic needs of vehicles and personnel, the construction of the three trenches needs to be staggered by a certain distance, which inevitably leads to a certain level difference in each pouring plane, which affects the construction quality. In addition, the constructi...
