Embodiment Construction

[0024] The present invention will be further described below in conjunction with accompanying drawing.

[0025] according to figure 1 and 2 Methods used for tunnel support are discussed in detail. In tunnel construction, corrugated plate components are used as the support of the tunnel. Corrugated plate assemblies can be used as primary support instead of primary lining. Corrugated plate components can also be used as post support instead of secondary lining. In specific tunnel construction, corrugated plate components can be used in primary support or / and post-support according to different engineering needs. This construction method can take advantage of the relatively high flexural strength and compressive strength of the corrugated plate to increase the stability of the tunnel and make the tunnel have the characteristics of high bearing capacity and strong earthquake resistance. At the same time, the corrugated board can be installed on site, which has the advantages ...

Abstract

The invention provides a tunnel supporting method. The tunnel supporting method comprises the step that a corrugated plate assembly is used as a tunnel supporting structure. The tunnel supporting method can better utilize good characteristics such as a high bearing capacity of a corrugated plate, so that a tunnel has the advantages of being easy and convenient to construct and good in economic benefit.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a support method for tunnels. Background technique [0002] With the acceleration of traffic construction, tunnel engineering has also developed rapidly. Regardless of whether it is a railway tunnel or a road tunnel, the safety requirements are extremely high, and the support structure of the tunnel must meet the requirements of safety, reliability and durability. [0003] In the prior art, the concrete composite lining method is often used to support the tunnel, and the initial support mainly bears all the loads in the construction phase and the main load in the operation phase. The secondary support is mainly used as a safety reserve to bear the load on the secondary lining caused by the possible deterioration of the primary support or the additional load caused by the creep of soft rock and changes in environmental conditions. [0004] However, concrete support o...
