Description
Technical Field
[0001] This utility model belongs to the technical field of concrete placing machines, specifically, it relates to a concrete placing machine for tunnel lining trolleys. Background Technology
[0002] Lining trolleys are indispensable non-standard products for secondary lining in tunnel construction. They mainly include simple lining trolleys, fully hydraulic automatic walking lining trolleys, and grid-type lining trolleys. Fully hydraulic lining trolleys can be further divided into side-arch type, full-circular needle beam type, bottom-form needle beam type, and full-circular through-form type. In hydraulic tunnel and bridge construction, lifting slipform, jacking slipform, and flipping formwork are also commonly used. Full-circular lining trolleys are often used in hydraulic tunnel construction where longitudinal joints in concrete construction are not permitted. Full-circular through-form trolleys are generally used when the span of a hydraulic tunnel is large. Side-arch type lining trolleys are the most widely used and are commonly used for secondary concrete lining construction in highway and railway tunnels and underground caverns. In the existing lining trolley operation, as the position moves, the material supply pipe needs to be connected to the pouring pipe at different locations. The pipe connection requires manual operation and climbing. Due to the relatively complex structure of the lining trolley, the range of motion is limited during operation, resulting in low pipe connection efficiency, long downtime, and affecting the efficiency of lining construction.
[0003] In view of this, this utility model is proposed. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the existing technology and provide a tunnel lining trolley concrete placing machine.
