Circumferential intellectualization reinforcing structure and reinforcing method for shield tunnel

Abstract

The invention discloses a shield tunnel circumferential intelligent reinforcement structure and a reinforcement method in the field of tunnel reinforcement technology, including a reinforcement structure body, the top of the reinforcement structure body is evenly fixed and installed with shield segment connecting columns by bolts, so that The bottom left end of the reinforcement structure body is fixedly connected with a support column by bolts, and the bottom right end of the reinforcement structure body is provided with a fixing groove, and the fixing groove and the support column cooperate with each other. This kind of shield tunnel circular intelligent reinforcement structure and reinforcement method, the design is reasonable, and the mortar layer, steel plate and carbon fiber composite molding are used to improve the ultimate bearing capacity and rigidity of the shield tunnel, and can realize rapid reinforcement of the tunnel under harsh conditions such as narrow space and short reinforcement time, and adopt CCD The image sensor, stress sensor and water seepage sensor can monitor the image inside the shield tunnel in real time, and monitor the strain distribution and water seepage of the reinforced structure.

Description

technical field [0001] The invention relates to the technical field of tunnel reinforcement, in particular to a circumferential intelligent reinforcement structure and a reinforcement method of a shield tunnel. Background technique [0002] In recent years, with the rapid development of the economy, various regions of the country have begun a period of large-scale construction of urban subways. Because the construction process has little impact on the surrounding environment, shield tunneling has almost become a must for the construction of subways. The shield tunnel structure is a typical assembled structure. High-strength bolts are used to connect the concrete prefabricated blocks vertically and horizontally to form a load-bearing structure. However, the underground conditions are complex, and changes in the groundwater level have a great influence on the external load of the structure. Under these influences, the shield tunnel structure will deform, such as the convergen...
