Small-section tunnel combined type straight wall lining formwork trolley

Abstract

The invention belongs to the technical field of tunnel construction equipment, and particularly relates to a combined straight wall lining formwork trolley for a small-section tunnel, which is mainly used for improving the construction efficiency and reducing the construction cost. The device comprises a left side formwork assembly, a right side formwork assembly, a formwork supporting rod and a moving mechanism, the formwork supporting rod is arranged between the two side formwork assemblies, and the length of the formwork supporting rod can be adjusted; the moving mechanism is connected to the lower end of the side template assembly; the formwork trolley further comprises a left guide rail and a right guide rail, the guide rails are laid on the poured concrete face, and the moving mechanism is arranged in the guide rails and can move in the guide rails. The positions of the formworks on the two sides are adjusted by adjusting the length of the supporting rods, concrete lining of a straight wall of a water section is achieved, the moving mechanisms connected to the lower ends of the formworks on the two sides are arranged in the guide rails, fixing of the two formwork sets at the lower ends is achieved, the structure is simple, and installation is convenient.

Description

technical field [0001] The invention belongs to the technical field of tunnel construction equipment, and in particular relates to a small-section tunnel combined straight wall lining formwork trolley, which is mainly used for improving construction efficiency and reducing construction costs. Background technique [0002] With the continuous development of engineering construction technology and the continuous updating and improvement of traditional construction techniques, different types of lining formwork trolleys are more and more used in engineering construction. Patent Publication No. CN214464238U discloses an adjustable formwork for a tunnel lining trolley, including a trolley frame, a top formwork group, a top formwork support mechanism, a side formwork assembly, a sideform support mechanism, a support leg and a walking mechanism; The top formwork group is arranged above the trolley frame, and includes a top base form set along the axis of the tunnel, and the top bas...

AI Technical Summary

Problems solved by technology

[0003] In this patent, the top formwork group and the side formwork assembly are used for full-section lining. However, in the initial stage of small hydraulic tunnel construction, in order to reduce the construction cost, for the tunnel body with stable surrounding rock, the design is only for the bottom plate of the water-passing section. Concrete lining with the straight wall, which makes the traditional full-section lining trolley not very suitable for this kind of project

Although traditional manual formwork can also meet the needs of construction, there are outstanding problems, such as high labor intensity, low construction efficiency, and obvious disadvantages in surface smoothness, safety and reliability.

[0004] In addition, the side formwork components in the above patent are symmetrically arranged on both sides of the trolley frame, the position of the side formwork components can be adjusted through the side form support mechanism, and the position of the side formwork can be adjusted with the formwork support rod to realize the side formwork The installation and form removal of the components, in order to realize the lining of the straight wall of the tunnel, the frame on the structure, the side formwork components and the formwork support rods are indispensable, and the structure is complex
