At the same time, due to the cumbersome construction technology, poor construction environment in the tunnel, high temperature, and large dust, The low degree of mechanization increases the physical exertion of operators, increases the labor intensity of operators, and also increases the difficulty of construction coordination, which restricts the laying efficiency and construction progress of waterproof materials. In such an environment, the laying of waterproof materials is prone to occur. The quality is poor, the welding quality cannot be guaranteed, the probability of water leakage increases, the construction efficiency is low, and there are quality hidden dangers such as insufficient welding length, damage, and irregular hanging of waterproof materials during the laying process. 2. At present, most of this type of trolley is only suitable for the laying of waterproof materials with a width of 3 to 4 meters. They are all mechanically assisted by manual deployment, manual lifting in place, and manual dragging to form a sag. Human factors have a great impact on the construction quality, and it is difficult to guarantee Forming the sag requirement does not solve the waterproof board sag formation process and waterproof board jacking process well, and there is no automatic control method, and at the same time restricts the popularization and use of 6-7m wide waterproof materials. 3. This type of trolley can only be used for laying waterproof materials, and cannot be used for laying steel bars. Additional professional equipment is required when laying steel bars, and its scope of application is poor. 4. There is no locking device for the operation after the trolley is raised. Once an accident occurs, it will cause serious safety accidents.
