Construction device for automatic circumferential cleaning and release agent applying of large-section tunnel lining trolley formwork and construction method

Abstract

The invention belongs to the technical field of tunnel construction and relates to a construction device for automatic circumferential cleaning and release agent applying of a large-section tunnel lining trolley formwork and a construction method. The construction device comprises an annular steel guide rail, a circumferential traction device, a cleaning and release agent applying device and a pipeline system, wherein the annular steel rail includes a first annular steel rail and a second annular steel rail; the annular steel guide rail is gantry-shaped; the first annular steel guide rail andthe second annular steel guide rail are arranged in parallel; a working area is arranged between the first annular steel guide rail and the second annular steel guide rail; the circumferential traction device and the cleaning and release agent applying device are arranged in the working area; the circumferential traction device is connected with and drives the cleaning and release agent applying device to move in the circumferential direction of the annular steel rail; and the circumferential traction device and the cleaning and release agent applying device are connected with the pipeline system. By means of the construction device and the construction method, a large manual cleaning working space and a significant cleaning effect are obtained.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction, and relates to a coating film construction device and method, in particular to a large-section tunnel lining trolley formwork ring-direction automatic cleaning coating film construction device and method. Background technique [0002] In the process of pouring the secondary lining of the tunnel, hydraulic lining trolleys are often used for formwork to improve construction efficiency. However, after the concrete is solidified and demoulded, solidified cement residues tend to stick to the steel formwork of the trolley, which affects the construction quality of the subsequent molding and pouring lining. It needs to be cleaned and evenly coated with a release agent. At present, most of the template cleaning work is manual. However, before cleaning, the second lining of the tunnel front section has been connected to the second lining reinforcement cage. The space for manual cleaning is ext...

Problems solved by technology

However, when cleaning and coating equipment is fixed, it is necessary to arrange dense grinding machinery and equipment. The cleaning and rotation process is easy to interact with each other, and the cleaning effect is not good; the mechanical cleaner can only be washed once during the advancing process, and it is difficult to remove the solidified cement. Clean up the slag; only use longitudinal cleaning and smearing, especially in large-section tunnels, it is difficult to ensure the cleaning effect of the entire ring during the longitudinal advancement of trolleys or cleaning equipment, and it is also difficult to apply the release agent evenly at the joints
