Abstract
Description
technical field
[0001] The invention relates to a surface plastering slide rail device used for pouring concrete bottom slabs in caves, in particular to a construction in caves that can conveniently control the elevation of surface-receiving concrete, greatly improve the surface flatness of concrete bottom slabs, and meet high-standard flatness requirements. The plastering slide rail device used for closing the surface when the concrete bottom slab is poured. Background technique
[0002] In order to achieve specific functions such as traffic, flow, and structural force, the concrete floor of the underground cavern often needs to be poured with concrete. In order to meet the requirements of use, sometimes higher requirements are put forward for the accuracy of the elevation and flatness of the concrete floor, especially for some over-current tunnels, the requirements are more stringent. When pouring the concrete bottom slab in the cave, there are generally cave wall rocks o...
