Problems solved by technology

In the past, the hydraulic tunnels constructed by open TBM can only be constructed sequentially, that is, the secondary lining can only be applied after the tunnel is partially or completely penetrated, and the bottom arch is usually constructed first, and then the side and top arches are constructed. The tunneling speed is relatively low and Detrimental to safety and quality during tunnel construction

Embodiment Construction

[0041] 1. If figure 1 and figure 2 As shown: the top mold (9, 15), the side mold (7), and the bottom mold (3) are a total of 5 groups of templates that together form a full-section template assembly (32), and the circumferential direction connection mode between each template is hinged, The axial connection mode is a bolt connection, and the hinge pin between the top form (9,15) and the side form (7) can be conveniently dismantled and installed, so as to be beneficial to demoulding and vertical formwork.

[0042] 2, the full-section template assembly (32) is a circular section, so it is impossible to realize variable diameter.

[0043] 3, stand assembly (31) is made up of top stand (11) and bottom stand (5).

[0044] 4. The upper platform (11) is a truss-type hollow structure, and there is enough space in the middle to facilitate the large-diameter ventilation hose (13) to pass through the trolley, and at the same time to minimize the resistance when the ventilation hose pa...

Abstract

The invention relates to an open type TBM (Tunnel Boring Machine) fullface synchronous lining trolley for a hydraulictunnel, which is characterized in that: a fullface pattern plate assembly slides on a girder front and back, so that lining construction is carried out alternately; the front and the back of the girder are respectively provided with a bearing for stabilizing the trolley; a space for a train to pass through is reserved in the girder; an upper rack is provided with a space for a large-diameter vent hose to pass through and protective measures thereof; the side face of a lower rack is provided with a continuous belt conveyor bearing platform; the front and the back of the girder are respectively provided with a transfer track system; and track skeletons can be removed and paved quickly through a crane system. According to the invention, the construction method for using the conventional open type TBM to tunnel the hydraulictunnel for secondary lining is thoroughly changed, the synchronous lining is realized, the total construction period for the long and deep tunnel is shortened, the safety during the construction and the quality of the tunnel are greatly improved, and the construction cost is reduced.

Description

Technical field: [0001] The invention relates to tunnel construction equipment, in particular to an open type TBM full-section synchronous lining trolley for hydraulic tunnels. Background technique: [0002] It is the most reasonable structural form for hydraulic tunnels used in hydropower projects and water transmission projects to adopt circular cross-sections. TBM construction for long tunnels will not only improve the tunnel construction level, but also help to improve tunnel utilization efficiency. In the past, the hydraulic tunnels constructed by open TBM can only be constructed sequentially, that is, the secondary lining can only be applied after the tunnel is partially or completely penetrated, and the bottom arch is usually constructed first, and then the side and top arches are constructed. The tunneling speed is relatively low and It is detrimental to the safety and quality during tunnel construction. Invention content: [0003] In order to solve the problem of...
