Description

TECHNICAL FIELD

[0001] The utility model relates to a tunnel construction technical field especially relates to a tunnel waterproofing membrane installation device. BACKGROUND

[0002] In the waterproof construction of buildings such as tunnels, basements and water conservancy projects, waterproofing membranes are widely used due to their excellent waterproof performance and durability.

[0003] The traditional waterproofing membrane installation method mainly relies on manual operation. The specific process is as follows: the membrane is transported to the installation position by manpower, and is laid and fixed manually.

[0004] However, when the flatness of the concrete surface is poor and the leveling is not in place, the difficulty of manually controlling the waterproofing membrane to adhere to the sprayed concrete surface increases significantly. This not only may cause wrinkles or bubbles in the laying process of the membrane, but also may cause cracking due to uneven stress on the membrane when pouring the second lining concrete. At the same time, a cavity is easily formed between the sprayed concrete surface and the waterproofing membrane, causing the waterproof material to be empty behind. This cavity not only weakens the overall performance of the waterproof layer, but also may change the stress state of the second lining structure, increasing the risk of tensile failure, threatening the long-term stability and safety of the tunnel.
