Problems solved by technology

When the tunnel length is not long, one trolley can line multiple tunnels, but because the traditional secondary lining trolley in the main tunnel cannot pass through the construction branch tunnel, it is often necessary to configure one or more trolleys for each tunnel Construction is carried out separately, or the trolley is dismantled and then transported to another tunnel by means of transportation and reassembled for construction
[0004] Therefore, in the working condition of parallel construction of multiple tunnels, the application of the lining trolley in the prior art has the following defects: (1) the distance between the portal frame and the formwork in the trolley is relatively short, and the demoulding shrinkage of the trolley It is very limited, and can only be demoulded and shrunk to less than 20 cm from the tunnel lining surface, which cannot meet the requirements of passing through the construction branch hole; (2) The trolley cannot pass through the construction branch hole, and each tunnel needs to be equipped with one or more units vehicles, the cost of equipment is greatly increased, and the assembly of multiple trolleys and the dismantling after construction are required to consume a lot of manpower and material resources, and more investment in construction and maintenance costs is required; (3) the existing trolleys are only used for Construction of straight tunnels, not suitable for tunnel construction with a certain amplitude

Embodiment 1

[0051] see Figure 1-Figure 5 , a variable cross-section tunnel lining trolley, including a portal frame system 1, a formwork system 2, a connecting part 3 connecting the portal frame system 1 and the template system 2, a walking mechanism 4 that drives the entire trolley to travel, and controls the entire platform. The control system for the movement of the trolley.

[0052] The gantry system 1 includes a frame part 1.1 and a jacking mechanism 1.2 and a bracket part 1.3 which are simultaneously arranged on the frame part 1.1, and the detailed structure is as follows:

[0053] The framework section 1.1 (see figure 1 and figure 2 ) is a mouth-shaped structure consisting of two gantry beams 1.11 and two gantry longitudinal beams 1.12.

[0054] The jacking mechanism 1.2 (see figure 1 and figure 2 ) includes four sets of jacking single pieces A arranged at the four corners of the frame part 1.1, and the lower ends of the guide columns A1 in the first-stage jacking parts of ...

Abstract

The invention provides a section-variable tunnel-crossing lining trolley which comprises a portal system, a template system, a connecting part and a walking mechanism, wherein the portal system comprises a frame part, a jacking mechanism and a bracket part; the jacking mechanism comprises multiple sets of jacking single pieces; each of the jacking single pieces comprises a multi-level jacking part; the bracket part comprises a truss girder and an adjusting support frame for a walking mechanism; the template system comprises a top template, a left template and a right template; and the connecting part comprises a support jack and a hydraulic cylinder. The section-variable tunnel-crossing lining trolley provided by the invention has the effects that the whole structure is simple; the assembling is convenient; the jacking mechanism is in a multi-level jacking mode; the trolley not only can adapt to the construction for the tunnel sections in different heights but also can achieve higher lifting volume; the trolley can meet the requirement of constructing multiple parallel tunnels by one trolley in the manner of constructing the working tunnel; due to the design of the bracket part, the lining trolley can meet the stability requirement, and meanwhile, the structure is simplified and the whole trolley can be supported.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a tunnel lining trolley with variable cross-section. Background technique [0002] Tunnel lining trolleys are more and more widely used in the prior art. In tunnel construction, multiple tunnels are often constructed in parallel, and construction branch tunnels are set between parallel tunnels. The construction branch tunnels intersect with the main tunnel at a non-perpendicular angle to facilitate the transfer of materials in the tunnel, and the cross-section of the construction branch tunnels Generally, it is much shorter than the cross section of the main hole. [0003] The variety of tunnel sections determines the specific characteristics of the trolleys. When the tunnel length is not long, one trolley can line multiple tunnels, but because the traditional secondary lining trolley in the main tunnel cannot pass through the construction branch tunnel, it is often...
