Problems solved by technology

[0002] With the rapid development of transportation, water conservancy, and urbanization tunnel projects, shield construction is more and more widely used in the construction of underground tunnels. The role is becoming more and more important, but the conventional design of the spout of the muck modifier, the rubber seal has insufficient resilience and is easy to wear or tear in the muck, causing the seal to fail and cause the spout of the muck modifier to be blocked

Abstract

The invention belongs to the technical field of tunneling shield. The nozzle device comprises a nozzle ring, a middle support plate placed at the center of the nozzle ring and an elastic sealing plate placed pressingly on the nozzle ring through a press ring. The side of the middle support plate is a convex conical structure. A plurality of the modifier agent ejection nozzles are evenly arranged on the middle support plate in a circle. The inner surface of the elastic sealing plate is a conical surface structure matching and adhering to the middle support plate. The elastic sealing plate comprises two fan shape sealing plates number 1 and number 2 matching with the elastic sealing plate. The sealing material of the elastic sealing plate is polyurethane which enhances the anti-tearing capacity of the ejection nozzle sealing. The nozzle ring is applies the design of the convex conical surface structure. The elastic sealing plate at the nozzle applies the conical surface design which can effectively reduce the elastic deformation in the working condition of the ejection nozzle, enhances the returning force and prolongs the service life of the sealing.

Description

technical field [0001] The invention belongs to the technical field of shield machine excavation, and in particular relates to a novel anti-clogging cutter head dregs soil modifier spout device. Background technique [0002] With the rapid development of transportation, water conservancy, and urbanization tunnel projects, shield construction is more and more widely used in the construction of underground tunnels. The role is becoming more and more important, and the conventional design of the nozzle of the soil modifier, the rubber seal has insufficient resilience and is easy to wear or tear in the soil, causing the seal to fail and cause the nozzle of the soil modifier to be blocked. Therefore, we urgently need to optimize the structure of the nozzle of the cutter head dregs modifier to reduce the risk of clogging of the dregs modifier nozzle. Contents of the invention [0003] The object of the present invention is to solve the above existing problems and deficiencies, ...
