Pouring process for carrying out tunnel secondary lining through novel hydraulic trolley

Abstract

The invention relates to a pouring process for carrying out tunnel secondary lining through a novel hydraulic trolley, and belongs to the technical field of tunnel lining equipment. According to the technical aim, the pouring process comprises the following steps of S1, mounting; S2, in-place operation; S3, pouring, wherein S301, secondary lining concrete is automatically poured by manually controlling a distribution system, and bilateral-symmetry window-by-window pouring from bottom to top is carried out during pouring, and S302, in the pouring process, auxiliary supports are additionally mounted on the inner sides of form boards, attached vibrators are mounted, and work windows are vibrated through inserted type vibration rods; and S4, maintaining and demolding, wherein S401, after concrete strength reaches the relevant regulation, the form boards are separated from forming surfaces and are maintained in time, and S402, the trolley is operated and controlled to advance to the next lining position to continue lining. The pouring process has the advantages that workers can carry out pouring work quite conveniently by saving quite labor, the labor intensity can be reduced, and the work efficiency can be improved.

Description

technical field [0001] The invention relates to the technical field of tunnel lining equipment, in particular to a pouring process for tunnel secondary lining by using a novel hydraulic trolley. Background technique [0002] The concrete construction of the second lining of the tunnel often uses the integral trolley as the formwork system, and then pumps the concrete into the mold for pouring. When the traditional method is used for the construction of the second-lined concrete, in order to realize the symmetrical pouring of horizontal, left, and right equal heights and uniform vertical layering, generally along the tunnel axis direction, multiple working windows are provided on the left and right sides of the trolley, and on the upper, middle, and lower layers. The disassembled chute transports the concrete from the outlet of the transfer pump to each working window.

Problems solved by technology

[0005] The technical solution of prior art 2 has the following defects: in the actual pouring process, the pumping pipelines are connected by pipe clamps and sealing rings, when changing the pumping window, it is necessary to stop feeding, and the pumping pipes are put on the pump pipe through the collaborative work of multiple people. Remove the pipe clamp, sealing ring, and pump pipe, then replace the pump pipe with a suitable length, adjust the position of the pipe outlet, and finally install and fix it with the next pumping interface, which is time-consuming and labor-intensive, and the workload is relatively large.
