Embodiment Construction

[0027] In order to make the above-mentioned features and advantages of the present invention easier to understand, the following specific embodiments are described in detail with reference to the accompanying drawings, but the present invention is not limited thereto.

[0028] refer to Figure 1-Figure 2 .

[0029] In a preferred embodiment of the present invention: an assembled tunnel lining structure composed of corrugated steel plates and UHPC, comprising a multi-section lining unit, the lining unit includes an inverted arch at the bottom of the tunnel, and the left and right ends of the inverted arch Side wall segments are provided, and a vault segment is erected between the tops of the wall segments on both sides. Both the side wall segments and the vault segments include corrugated steel roofs and UHPC ribbed beams. The corrugated steel roofs Cement mortar is filled with the excavation surface of the tunnel to form the primary support of the tunnel, and cast-in-situ con...

Abstract

The invention relates to a corrugated steel plate and UHPC combined fabricated tunnel lining structure. The fabricated tunnel lining structure comprises a plurality of lining units, each lining unit comprises an inverted arch located at the bottom of a tunnel, the left end and the right end of each inverted arch are each provided with a side wall section, an arch crown section is erected between the tops of the two side wall sections, each side wall section and each arch crown section each comprise a corrugated steel top plate and a UHPC rib plate beam, cement mortar fills the spaces between the corrugated steel top plates and the excavation face of the tunnel to form a primary support of the tunnel, and cast-in-place concrete fills the spaces between the corrugated steel top plates and the UHPC rib plate beams to form a permanent support of the tunnel. The corrugated steel plate and UHPC combined fabricated tunnel lining structure is simple in structure, reasonable in design, convenient to construct and capable of being widely applied to tunnel structures, the construction efficiency is improved, and the service life is prolonged.

Description

technical field [0001] The invention relates to an assembled tunnel lining structure combined with corrugated steel plates and UHPC and a construction method thereof. Background technique [0002] Tunnels are a very important part of my country's transportation infrastructure. In order to prevent deformation or collapse of the surrounding rock, in most cases, reinforced concrete and steel are used to build composite linings along the periphery of the tunnel body, that is, primary support and secondary lining. However, the existing tunnels also suffer from poor construction conditions, numerous construction procedures, difficulty in guaranteeing construction quality, tunnel frost damage, water leakage, lining cracks and other diseases, which increase the cost of tunnel operation and maintenance and reduce the service life. Contents of the invention [0003] The purpose of the present invention is to provide an assembled tunnel lining structure composed of corrugated steel p...
