Abstract

The invention discloses a space latticed shell type anchoring and shotcreting preliminary supporting structure, a tunnel and a tunnel supporting construction method, and relates to the technical fieldof tunnel construction. The space latticed shell type anchoring and shotcreting preliminary supporting structure comprises a latticed shell component, sprayed concrete and a plurality of anchor rods.A shell supporting space can be defined by the latticed shell component and surrounding rock, the latticed shell component comprises a plurality of connecting rod pieces and a plurality of connectingfixing pieces, every two adjacent connecting rod pieces are connected through the corresponding connecting fixing piece, the latticed shell component can extend in the first preset direction, one endof each anchor rod is connected to the corresponding connecting fixing piece, and the other end of each anchor rod extends into the surrounding rock in the direction away from the shell supporting space, and the sprayed concrete is arranged between the latticed shell component and the surrounding rock and in a hollow part defined by the plurality of connecting rods; and the latticed shell component can form a supporting surface on the preset tunnel excavation space surface. The space latticed shell type anchoring and shotcreting preliminary supporting structure can ensure timely constructionof tunnel preliminary supporting, uniform and reasonable space stress, material saving, safety and economy.

Description

technical field [0001] The present application relates to the technical field of tunnel construction, in particular, to a space reticulated shell type anchor-sprayed initial support structure, a tunnel and a tunnel support construction method. Background technique [0002] After the excavation of the tunnel, in order to control the stress release and deformation of the surrounding rock in an appropriate amount, increase the safety of the structure and facilitate the construction, immediately after the excavation of the tunnel, a structural layer with low stiffness and a part of the permanent bearing structure is applied, which is called primary support. The initial support of the tunnel must be implemented in a timely manner closely following the tunnel excavation work surface. At the same time, relevant operations of monitoring and measurement should be carried out according to the design requirements. For tunnels located in unfavorable geological areas, the initial support ...
