Description

Technical Field

[0001] The utility model relates to the technical field of tunnel construction, in particular to a drainage board laying device in a tunnel. Background Art

[0002] Traditionally, the laying of drainage boards in tunnel segments is done manually by setting up scaffolding or ladders. Although the traditional method can complete the laying of drainage boards, it has great safety risks and difficulty. When the drainage boards are in contact with the tunnel segments, they cannot be completely fitted with the tunnel segments due to the weight of the materials. There are many bulges and wrinkles, which do not meet the quality requirements for laying drainage boards. Due to the long curing time of the glue of the drainage boards, the construction labor intensity of the operators is high, the working hours are long, and the work efficiency is low. When the drainage boards are laid and transferred to the next working surface, the traditional method of moving the operating device is difficult and requires a large investment in personnel costs.

[0003] The existing application is 201710777569.2, which is a tunnel waterproof board laying trolley, including multiple trolley door frames arranged in parallel, the trolley door frames are provided with arch rings that match the inner wall of the tunnel, and the two adjacent arch rings are provided with climbing mechanisms, which are installed on the arch rings through a transmission component, and the climbing mechanism is provided with a laying component and a smoothing component. The climbing mechanism includes two crawling boxes that are respectively connected to the two adjacent arch rings by transmission, and a crawling trolley installed between the two crawling boxes, and the crawling trolley is installed on the crawling box by rotating a shaft. The tunnel waterproof board laying trolley has a complex structure and high manufacturing cost. In addition, the waterproof board is laid by moving the laying component and the smoothing component along the arch ring. Only waterproof boards of corresponding sizes can be laid in one place, and the laying efficiency is not high. Utility Model Content
