Multifunctional variable cross-section lining trolley for tunnel

Abstract

The invention provides a multifunctional variable cross-section lining trolley for a tunnel. The multifunctional variable cross-section lining trolley comprises a triangular support system, a formwork system, a full-hydraulic system, a concrete distribution system, a travelling system and the like, the formwork system comprises side formworks and a middle variable cross-section formwork, the cross-section sizes of the side formworks on two sides are invariable, the middle variable cross-section formwork is arranged at the center of the top of a tunnel lining, and the width of the middle variable cross-section formwork is variable. By the aid of the lining trolley, factory-like production of the tunnel lining trolley and standardization of components can be realized, the overall weight of the trolley is decreased by 20%, labor intensity is reduced, and working efficiency is improved.

Description

technical field [0001] The invention relates to a tunnel multifunctional variable section lining trolley, which belongs to the field of tunnel construction equipment. . Background technique [0002] The construction and development of tunnel engineering is one of the greatest scientific and technological achievements of our country in the 20th century. It has effectively promoted the development of our country's transportation industry, and also promoted the development of related disciplines such as civil engineering and water conservancy engineering. At present, the total length of tunnels and the level of construction technology in my country are world-leading. [0003] The 21st century should be the century for the development and utilization of underground caverns. In the sustainable development strategy of the 21st century, the ground land space is limited and most of it has been used. Now, the construction of underground tunnels will undoubtedly make a huge contributi...

AI Technical Summary

Problems solved by technology

[0008] (1) The weight of the trolley is too large, it is difficult to transport and assemble, and it causes serious waste of materials

[0009] (2) The trolley component is a one-time non-standard product, which cannot meet the construction requirements of variable cross-section tunnel lining

[0010] (3) The loading system adopts hydraulic pressure and supporting screw to load respectively. The pressure cannot be automatically controlled when pouring concrete, which is easy to cause quality defects such as run-out and wrong platform. When pouring to the top, sometimes the top formwork will be compressed and deformed or even hit collapse phenomenon

[0011] (4) The support system adopts a gantry structure, which is prone to uneven deformation, poor overall rigidity, and serious waste of materials

[0013] (6) It is difficult to control the overlap between the trolley formwork and the short side wall and the staggered seam
