Tunnel automatic waterproof plate trolley

Abstract

The invention provides an automatic waterproof board trolley for tunnels, belonging to the technical field of tunnel construction, which includes a trolley main body, a walking trolley, a cloth rolling device, a rolling device and a trolley walking track; the trolley main body is provided with a road walking mechanism; The cloth device includes a driving device and a cloth rolling shaft; the driving device drives the cloth rolling shaft to work; the rolling device includes a bracket and a rolling roller. The tunnel automatic waterproof board trolley realizes the automatic release of the waterproof board through the rolling device, and rolls the deployed waterproof cloth and the tunnel wall tightly through the rolling device to avoid wrinkles of the waterproof board, and the rolling device can walk along The trolley moves along the trolley track and is suitable for the entire tunnel contour; therefore, it improves the laying accuracy of the waterproof board, so that the waterproof board can fit the tunnel wall completely according to the tunnel contour, without a large gap in the middle, and ensures the reserved sag, thereby improving the waterproof effect; at the same time, reducing the labor intensity of workers and improving work efficiency.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to an automatic waterproof board trolley for tunnels. Background technique [0002] During the construction of the tunnel, geotextiles and waterproof boards need to be laid successively on the tunnel section to form a water-proof and drainage-enclosed surface. At the same time, it combines comprehensive waterproof measures such as burying drainage pipes and installing construction joint waterstops to achieve the waterproof effect of tunnel lining. [0003] Composite waterproof boards have been widely used in current projects. During the laying process, they are attached to the wall according to the contour of the tunnel. Now there are mainly the following laying methods: After opening the whole roll of waterproof boards, use the telescopic device to prop up the waterproof boards to the top The disadvantage of this method is that the waterproof board cannot be completely...

Problems solved by technology

[0003] Composite waterproof boards have been widely used in current projects. During the laying process, they are attached to the wall according to the contour of the tunnel. Now there are mainly the following laying methods: After opening the whole roll of waterproof boards, use the telescopic device to prop up the waterproof boards to the top The disadvantage of this method is that the waterproof board cannot be completely attached to the tunnel wall, and there may be a gap in the middle, and it is not suitable for the combination of geotextile and waterproof board For the composite waterproof board, it is necessary to manually lift the waterproof board, nail the nails on the tunnel wall according to the position of the string on the geotextile, and then tie the waterproof board to the nails. The waterproof board laid in this way is very Irregular, due to the limitation of manual laying waterproof board technology, it must be laid manually with load, the difficulty of unfolding, the sag reservation is directly limited by the difficulty of construction, there is no guarantee that the reserved sag will be achieved, and the width of the waterproof board will be affected to a certain extent. The manual laying of the waterproof board process cannot be accurately aligned, which is the main process defect that causes the water leakage of the waterproof board welding seam. Therefore, it is necessary to design a device that can directly stick the waterproof board to the tunnel wall according to the tunnel contour.
