Problems solved by technology

[0004] However, concrete support often has problems such as complex construction and long construction period.
At the same time, for the alpine region, the concrete support often has the problem of frost heave, which will cause the concrete to fall, which will bring safety problems

Embodiment Construction

[0033]The present invention will be further described below in conjunction with the drawings. It should be noted that although the following embodiments are described by installing the corrugated board assembly for support of the present invention in a tunnel as an example, those skilled in the art can understand that the corrugated board assembly for support according to the present invention can also be used. When applied to culverts or other similar engineering applications, this also belongs to the protection scope of the present invention.

[0034]figure 1 It shows a schematic diagram of applying the corrugated board assembly for supporting according to the present invention in a tunnel. Such asfigure 1 As shown, a corrugated board assembly 100 for support is provided on the inner wall of the tunnel 1. The corrugated board assembly 100 for supporting usually consists of a plurality of corrugated board units along the transverse direction of the tunnel (figure 1 The direction X in ...

Abstract

The invention provides a corrugated plate assembly for supporting, and the corrugated plate assembly for supporting is suitable for tunnels. The corrugated plate assembly for supporting is formed by connecting a plurality of corrugated plate units in the transverse and longitudinal directions. The invention further relates to a tunnel supporting method with the corrugated plate assembly for supporting adopted.

Description

Technical field[0001]The present invention relates to the field of tunnel construction, in particular to a corrugated board component for supporting and a tunnel supporting method using the corrugated board component for supporting.Background technique[0002]With the acceleration of traffic construction, the tunnel and culvert project has also developed rapidly. Whether for railway tunnels, highway tunnels or related culverts, the safety requirements are extremely high. Therefore, the supporting structure of the tunnel or culvert must meet the requirements of safety, reliability and durability.[0003]In the prior art, concrete composite lining methods are often used to support tunnels or culverts. Generally speaking, its initial support mainly bears all the loads in the construction phase and the main loads in the operation phase. The secondary support is mainly used as a safety reserve to bear the additional load caused by the load on the secondary lining due to the possible deterior...
