[0035] Example one
[0036] Combine below Figure 1 to Figure 5 A detailed description will be given to the construction method of the clutch type formwork trolley, trolley assembly and underground passage concrete of the present invention.
[0037] Such as figure 1 As shown, a clutch type formwork trolley used for concrete pouring construction of an underground passage includes a top formwork trolley 31, a side formwork 10 and a vertical support rod 20. The side formwork 10 is distributed on both sides of the top formwork trolley 31 and The wooden formwork 14 is connected to the top formwork trolley 31; the bottom of the side formwork 10 is provided with a moving guide 11, which cooperates with the moving pulley 21 provided on the vertical support rod 20 to drive the side formwork 10 to move longitudinally.
[0038] The top template trolley 31 includes at least two top template trolley units arranged side by side and detachably connected. Each top template trolley unit includes a to...

[0046] Continue to combine below Figure 1 to Figure 5 The concrete construction method of the underground passage is explained in detail. The concrete construction method of the underground passage is to divide the underground passage into several construction sections for continuous construction, including the following steps:
[0047] S001: Lay the bottom plate 40 of the underground passage, and place the trolley components on the bottom plate 40. The two trolley components are the top formwork trolley 1 and the top formwork trolley 2, so that the top formwork trolley 1 is located in the first construction section. Top formwork trolley 2 is located in the second construction section;
[0048] S002: Please continue to refer figure 2 , Pouring concrete in the first construction section to form the structural side wall and structural roof of the first construction section at one time;
[0049] S003: Please continue to refer figure 1 After the concrete strength...
