Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example:

[0030] Please see Figure 1-2A rebar waterproofing membrane trolley includes a trolley that can move within a tunnel. The trolley is equipped with a waterproofing membrane laying structure and a rebar tying platform. The waterproofing membrane laying structure includes an upper frame longitudinal moving trolley 1 that can move longitudinally along the trolley. An annular waterproofing membrane laying trolley 2 that can move in a circle is provided on the upper frame longitudinal moving trolley 1. The annular waterproofing membrane laying trolley 2 is equipped with a waterproofing membrane roll lifting device 3, an automatic waterproofing membrane unfolding and guiding mechanism, and an arch auxiliary support device. The rebar tying platform includes a multi-layer platform and ladders set between the multi-layer platforms, as well as a hanging plate small platform 4 set on the upper frame longitudinal moving trolley.

[0031] Specifically, the top of the trolley is fixedly installed with two sets of longitudinal beams 5, each equipped with a trolley track, which allow the longitudinal moving trolley 1 to move longitudinally. One end of the two sets of longitudinal beams is fixedly connected by a track crossbeam, and a track brace is fixedly connected between the track crossbeam and the trolley. The longitudinal moving trolley 1 is fixedly installed with an annular track 10, which allows the annular waterproof membrane laying trolley 2 to slide annularly.

[0032] Specifically, the longitudinal trolley 1 is equipped with guide wheels 6 that slide and cooperate with the trolley guide.

[0033] Specifically, the trolley also includes a gantry system, a walking system 7, a support system, a main control box, and an electrical control cabinet 8.

[0034] Specifically, the gantry system includes a bottom longitudinal beam, gantry uprights, gantry crossbeams, gantry diagonal braces, duct support 9, longitudinal connecting frame, and longitudinal diagonal braces.

[0035] Specifically, the support system includes a lifting cylinder 11 fixedly installed at the bottom of the trolley, with a support leg fixedly installed at the bottom output end of the lifting cylinder, and a hydraulic pump station 12 fixedly installed at the bottom of the trolley.

[0036] Specifically, the walking system also includes guide devices 13 installed on both sides of the bottom of the trolley.

[0037] Specifically, guardrails 14 are installed at each level of the climbing frame and each platform.

[0038] Specifically, the multi-layer platform is configured as three layers, namely a first-layer platform 15, a second-layer platform 16, and a third-layer platform 17, and is equipped with a first-layer ladder 18, a second-layer ladder 19, and a third-layer ladder 20. A temporary reinforcing support 21 is fixedly installed between the bottom of the first-layer ladder 18 and the trolley.

[0039] Construction Process: The trolley travels along a multi-functional waterproof fabric and rebar trolley, which consists of various intelligent operating systems. The trolley is equipped with an automatic walking system and a walking guide device, enabling it to safely and accurately reach the construction position along the tunnel's longitudinal direction. Upon arrival, the trolley first checks whether the initial tunnel support excavation in that area meets the requirements, facilitating efficient subsequent construction work. Hydraulic outriggers are then used to adjust the trolley's height, ensuring better contact with the tunnel surface. A waterproof membrane feeding system suspends 22 rolls of waterproof membrane in a single operation, eliminating the need for manual handling and secondary winding. This facilitates manual welding of the waterproof fabric, significantly reducing labor intensity, improving work efficiency, and enhancing the waterproof fabric laying effect. The waterproof fabric laying is controlled via an electrical control box or remote control, and the waterproof fabric is pressed and fixed. Operators can easily complete the work by standing on a side operating platform. This process is part of the current construction... During the process, the laying of the waterproof tarpaulin is strictly following the prescribed sequence. Once the current 12-meter-long waterproof tarpaulin segment is fully laid and passes the necessary quality inspection, the next critical process can be smoothly initiated: the laying of the reinforcing steel. In the reinforcing steel laying stage, this machine features a specially designed, stable, and spacious multi-functional operating platform, providing a revolutionary change for the reinforcing steel binding operation. Operators can stand safely and comfortably on the platform to accurately position, efficiently bind, and weld the reinforcing steel mesh. Compared to traditional scaffolding and high-altitude climbing operations, this platform design completely eliminates the risk of falls from heights, significantly improving operational safety. More importantly, it significantly optimizes the workflow, moving away from high-risk and inefficient operations, overcoming manual limitations, and driving tunnel construction towards automation, standardization, and a future of intelligent construction through innovative equipment.
