Abstract

The invention discloses a high-strength joint construction device suitable for composite cavity components. The high-strength joint construction device is applied to the composite cavity components where a plurality of cavities are formed. Cavity walls are arranged between adjacent cavities. The high-strength joint construction device comprises a high-strength connection plate arranged at the joint of the adjacent composite cavity components, a nut and a bolt. A connector assembly face located on the first side is formed on the two composite cavity components. The high-strength connection plates is attached and connected to the connector assembly face. Two connection parts are formed on the high-strength connection plate and are connected to the two composite cavity components correspondingly. The nut penetrates through the cavity walls from the second side of the composite cavity components to the first side. Connection holes are formed in the connection parts. The bolt penetrates through the connection holes and is in threaded connection with the nut. Specifically, the high-strength connection plate covers the joint between the adjacent composite cavity components, high-strengthconnection between the composite cavity components is achieved, the high-strength joint construction device has high tensile resistance and bending resistance, and a high-strength continuum is formedto effectively reinforce a stagger-jointed assembling tunnel.

Description

technical field [0001] The invention relates to the technical field of tunnel construction, in particular to a high-strength joint construction device suitable for composite cavity components. Background technique [0002] The shield method tunnel segment assembly tunnel construction technology has been widely used in subway, highway, drainage and other tunnel projects at home and abroad. However, the shield tunnel structure is composed of various tunnel segments assembled by bolts, and its stress structure presents a multi-hinge discontinuous circular arch structure, which relies heavily on the existence of lateral arch thrust. Accidental unloading, etc., will lead to large deformation of the structure, and the safety, reliability and durability of the structure will be seriously affected. It is urgent to strengthen the tunnel in time. Structural failure, resulting in accidents such as tunnel collapse. [0003] In order to get rid of this risk, it is an important and effe...
