[0002] With my country's rapid economic and social development, its population is also growing rapidly, making surface space increasingly crowded. Urban underground tunnels have seen significant development due to their advantages, such as resistance to severe weather and ability to alleviate surface traffic congestion. Underground tunnels are crucial in urban construction, relieving surface congestion by building a three-dimensional transportation network, efficiently utilizing underground space to release surface resources, and integrating municipal infrastructure to improve management efficiency. Tunnels also enhance cities' disaster prevention and mitigation capabilities, such as flood control, drainage, and emergency evacuation, while reducing environmental pollution and supporting sustainable development. Furthermore, tunnel construction drives economic growth, enhances urban competitiveness, and promotes engineering progress and intelligent operation and maintenance through technological innovation. Overall, underground tunnels are a key support for the efficient, safe, and green development of modern cities.

[0003] Leakage sealing is a common problem during tunnel construction. Because tunnels are underground structures, leakage can occur under the pressure of groundwater and soil, significantly impacting their usability and safety. Therefore, leakage sealing technology is particularly important in tunnel construction. In recent years, prefabricated tunnel construction technology has been widely used, becoming a major technology in modern tunnel construction due to its high efficiency, safety, and energy saving. However, prefabricated shield tunneling leakage sealing trolley supports have received relatively little attention, even though this technology is an indispensable part of tunnel leakage sealing techniques.

[0021] Figure 1-3 A simple prefabricated tunnel sliding trolley is shown, including a bottom mounting frame and a mounting platform 5 disposed on the mounting frame;

[0022] The bottom mounting frame consists of two symmetrically arranged support frames. As one embodiment of this invention, the distance between the two sets of vertical support frames is 3m, allowing electric vehicles to pass through. Each support frame includes three parallel vertical rods 1 and a horizontal rod 2 assembled with the vertical rods 1. The horizontal rods include at least two arranged vertically in the middle and one arranged at the bottom.

The other side of the lower platform support plate 7 is connected to the third horizontal bar 23. As one embodiment of this application, to ensure the stability of the support frame, each support frame has two first and two diagonal bars. The first and second diagonal bars strengthen the frame and prevent instability, increasing its load-bearing capacity and rigidity, while also enhancing its anti-overturning ability.

[0024] Storage baskets 6 are provided on the front and rear sides of the lower platform support plate 7; the storage baskets 6 are located between the second crossbar 22 and the third crossbar 23.

After preparation, the trolley support is moved to the construction site along the rails. The pulleys are locked, and the trolley is then mounted on the installation platform using an external detachable climbing frame. During segment assembly, leaks can be sealed in the gaps and areas without interference. A fast-curing sealing material is selected and used to fill these gaps and areas without interference. After completion, the trolley can be moved without affecting subsequent construction.
