Description

Intelligent cloth vibrating device for lining construction and working method thereof Technical Field The invention relates to the technical field of lining construction, in particular to an intelligent cloth vibrating device for lining construction and a working method thereof. Background Lining construction refers to permanent supporting structures built around the tunnel body with reinforced concrete or other materials to prevent deformation or collapse of surrounding rocks. Lining technology is commonly applied in tunnel engineering and water conservancy channels. In the casting process, a plurality of rows and columns of windows are usually staggered on the templates on two sides of the trolley for casting concrete. The tunnel is generally in an arch-shaped pile structure, and the structure requires that parameters such as concrete pouring time, pressure, initial setting time and the like on two sides of a lining layer of the tunnel are kept as consistent as possible, so that the properties of concrete materials of the lining concrete layer are kept consistent, and therefore, when the arch-shaped lining layer is stressed, the arch-shaped structure is more stable, stress deformation tends to be symmetrical, and transverse component forces can be offset. If the pouring solidification material properties of two sides of the lining layer are inconsistent, the force transmission size is different, the stress deformation is asymmetric, and under a long-term stress state, the transverse stress is oriented to one side, so that one side is subjected to transverse shearing force, and the structure is easily damaged. Therefore, the casting working conditions (temperature, casting pressure, casting flow, initial setting time, final setting time and the like) on two sides of the secondary lining layer of the tunnel are required to be kept consistent finally. The existing distributing device is mainly used for distributing materials on one side, namely, one pouring opening is formed in one pouring trolley, and the pouring strategy is that after concrete on one side is poured, the pouring opening is rotated to the other side, and then a concrete layer on the other side is poured. The tunnel lining trolley template is also of a bilateral symmetry arch structure, concrete on one side is poured firstly, pouring pressure can act on the lining template, the lining template is stressed on one side, the stress is uneven, when pouring is carried out, the template is easy to laterally move, the center of the template deviates from the center of a tunnel, and the center of a lining layer formed deviates from the center of the tunnel.
