Problems solved by technology

[0002] At present, when constructing tunnels in our country, in order to facilitate the passage of other construction vehicles such as transportation, temporary trestles are usually built in the tunnels. However, in the process of building trestles, a lot of manpower and raw materials are required. Disassembly will seriously affect the construction progress; at the same time, various safety hazards are prone to occur, which seriously threaten the life safety of construction personnel; while the existing mechanical trestle has a relatively complex structure, a huge mechanism, high procurement costs, and single function, which cannot be used in small places. Practical, low usage

Embodiment Construction

[0013] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0014] As shown in the figure, a tunnel inverted arch self-propelled trestle is composed of a rear approach bridge (1), a driving wheel (2), a bridge body (3), a side form system (4), a walking support (5), and a front approach bridge (6). ), the front axle support (7), the integral translation oil cylinder (8), the foundation oil cylinder (9), and the formwork mobile oil cylinder (10) constitute;

[0015] The rear approach bridge (1) is arranged at the rear of the bridge body (3), the driving wheel (2) is arranged under the rear end of the bridge body (3), and the walking support (5) is arranged under the bridge body (3), The front approach bridge (6) is arranged in front of the bridge body (3), the front bridge support (7) is arranged under the front approach bridge (6), and the overall translation oil cylinder (8) is arranged under the front end of the bri...

Abstract

The invention provides a tunnel inverted-arch self-propelled trestle. Walking supports and horizontal moving oil cylinders are arranged below a trestle body, inverted-arch side formworks are arranged on the two sides of the trestle body, and thus the trestle can move front, back, left and right. When a construction vehicle walks to a construction road section through the trestle, concrete is poured, and inverted-arch work is started through the inverted-arch side formworks. A rear approach bridge is arranged behind the trestle body, a driving wheel is arranged below the rear end of the trestle body, the walking supports are arranged below the trestle body, a front approach bridge is arranged in front of the trestle body, a front trestle brace is arranged below the front approach bridge, the integral horizontal moving oil cylinders are arranged below the front end of the trestle body, foot margin oil cylinders are arranged below the integral horizontal moving oil cylinders, side formwork systems are arranged on the two sides of the trestle body, and formwork horizontal moving oil cylinders are arranged above the side formwork systems. The tunnel inverted-arch self-propelled trestle is simple in structure and low in cost and fault rate, inverted-arch construction can be carried out while vehicle traffic is ensured, the tunnel building speed can be effectively ensured, and building accidents are effectively reduced.

Description

Technical field [0001] The invention relates to the field of tunnel trestles, in particular to a tunnel inverted arch self-propelled trestle. Background technique [0002] At present, when constructing tunnels in our country, in order to facilitate the passage of other construction vehicles such as transportation, temporary trestles are usually built in the tunnels. However, in the process of building trestles, a lot of manpower and raw materials are required. Disassembly will seriously affect the construction progress; at the same time, various safety hazards are prone to occur, which seriously threaten the life safety of construction personnel; while the existing mechanical trestle has a relatively complex structure, a huge mechanism, high procurement costs, and single function, which cannot be used in small places. Practical and low usage. Contents of the invention [0003] In order to overcome the deficiencies in the prior art, the present invention provides a self-pr...
