Slip form trolley and method for annularly pouring concrete in adit

Abstract

The invention belongs to the technical field of constructional engineering concrete construction, and discloses a slip form trolley and method for annularly pouring concrete in an adit. The slip form trolley comprises a prefabricated or cast-in-place trolley mounting bottom arch block and a slip form trolley body, wherein second guiding rails are fixedly mounted on the two sides of the bottom of an inner cavity of a prefabricated bottom arch; and connecting and fixing plates are fixedly mounted at the bottoms of the two sides of the slip form trolley body correspondingly. According to the slip form trolley and method for the annularly pouring concrete in the adit, transmission gears, arc-shaped sliding modules and pneumatic cylinders are arranged, a movable frame can move downwards due to operation of the pneumatic cylinders, so that the four transmission gears are driven to rotate, rotation of the two arc-shaped sliding modules is achieved, an operator can conveniently conduct concrete pouring operation and treatment of a preformed groove formwork, and the construction efficiency of the operator is improved; meanwhile, the number of shaping formworks is fundamentally reduced, materials for overall manufacturing of the slip form trolley body are reduced, the construction cost input is effectively controlled, and therefore the practicability of the slip form trolley is improved.

Description

technical field [0001] The invention belongs to the technical field of concrete construction in construction engineering, and in particular relates to a sliding form trolley for circularly pouring concrete in a flat hole. Background technique [0002] Tunnel lining trolley is a special equipment that must be used in the secondary lining of the tunnel construction process. It is used for the concrete lining construction of the inner wall of the tunnel. The concrete lining trolley is an indispensable non-standard product for the secondary lining in the tunnel construction process. It mainly includes Simple lining trolley, fully hydraulic automatic walking lining trolley and grid-type lining trolley, full hydraulic lining trolley can be divided into side-top arch type, full-circle needle beam type, bottom mold needle beam type, and full-circle walking type Wait. Tunnel engineering for various purposes has been widely used. Conventional steel formwork trolleys can only be appli...

Problems solved by technology

Tunnel engineering for various purposes has been widely used. Conventional steel formwork trolleys can only be applied to tunnels with the same lining section, but now there are more than one form of tunnel sections for other purposes, such as prestressed lining. Anchor grooves and other structures are reserved in advance, resulting in a variety of lining cross-section forms. Therefore, there are obvious limitations in the commonly used mobile steel formwork trolleys and needle beam steel formwork trolleys for tunnel lining. The processing is relatively cumbersome, and the post-processing of the concrete surface quality defects after the conventional steel formwork trolley is demoulded requires a lot of manpower and material resources, so it needs to be improved
