Problems solved by technology
[0003] With the development of urban construction in our country, underground rail transit, cross-river tunnels and other underground projects are increasing day by day, and the shield tunneling distance is getting longer and longer. Strictly, the pressure-resistant sealing performance of the shield tail seal brush directly affects the sealing safety of the construction process. At present, there is no uniform testing standard for the pressure resistance performance of the shield tail seal brush in China, and the performance of the product cannot be judged. It is completely based on experience. Often the shield tail seal brush cannot meet the actual sealing and pressure resistance requirements during use

Abstract
The invention belongs to the technical field of shield tunneling machines, and relates to equipment for testing the airtightness and pressure resistance of a shield tail brush of a shield tunneling machine. The equipment comprises a motor base, a core rod which is horizontally fixed above a motor base, a testing pipe piece sleeving the core rod, a transmission screw rod parallel to a side of the core rod, and an assembly tool disposed at a side of the testing pipe piece. The transmission screw rod passes through the testing pipe piece, and the testing pipe piece is fixedly provided with a threaded sleeve engaged with the transmission screw rod. An assembly tool is in a cylindrical structure, wherein one surface, facing the testing pipe piece, of the cylindrical structure is opened. The assembly tool comprises a disc body, and the core shaft and the transmission screw rod pass through the disc body. The assembly tool also comprises a cylinder fixed at one side of the disc body, and the disc body is provided with a water injection mouth which is connected with a water injection pipe. The water injection pipe is provided with a water pressure meter, and the cylinder is provided with a plurality of pressure meters. The equipment can simulate the working state of the shield tail brush, and carries out the testing of airtightness and pressure resistance.
Description
Technical field [0001] The invention relates to the technical field of shield machines, in particular to a shield tail brush sealing pressure test equipment. Background technique [0002] Shield tunneling machine, full name shield tunnel boring machine, is a kind of special engineering machinery for tunnel boring. Modern shield tunneling machine integrates optical, mechanical, electrical, hydraulic, sensor and information technology, and has the ability to excavate and cut soil. The functions of mass, rock, conveying soil sludge, assembling tunnel lining, measuring guide deviation and other functions involve geology, civil engineering, machinery, mechanics, hydraulics, electrical, control, measurement and other disciplines and technologies, and they must be "tailored" according to different geology. It is designed and manufactured with high reliability requirements. Shield tunneling machines have been widely used in subway, railway, highway, municipal, hydropower and other tunne...
