A Segment Secondary Lining Equipment with Continuous Tension

Abstract

The invention discloses a segment secondary lining equipment with continuous tension, which includes a car body, on which a segment assembly machine, a segment crane, a pea gravel injection system, a mortar injection system, a hydraulic system, Compressed air system, electronic control system, a support shield is fixed at the front of the car body, and a continuous tensioning mechanism is provided at the rear of the car body to provide reaction force when the car body is moving forward. The continuous tensioning mechanism is set at the opening of the tunnel place. In the process of advancing the equipment, the continuous tensioning mechanism placed at the tunnel opening provides sufficient and continuous reaction force, so that the propulsion cylinder supporting the shield acts on the secondary lining segment during the propulsion process, so that the pipe The sheet is pressed well, and the reaction force provided by the continuous tensioning mechanism acts on the tunnel opening and does not contact the tunnel wall of the primary lining, thus avoiding damage to the primary lining tunnel.

Description

technical field [0001] The invention relates to a segment secondary lining equipment with continuous tension. Background technique [0002] With the application of shield tunnels more and more widely, from the early road and railway tunnels to today's subways, cables, drainage channels, etc. The diversified applications of tunnels have made higher requirements for the structural strength, service life and waterproof ability of tunnels. Excavating tunnels in relatively narrow areas is usually not suitable for shield machine operations, and methods such as open cut, concealed cut, and cover excavation are often used. These methods often use reinforced concrete to reinforce the excavated tunnels, and use reinforced concrete to reinforce them. Tunnels often have poor waterproof performance and weak structural strength, which requires secondary lining segments to meet the special requirements of the tunnel. [0003] The existing segment secondary lining equipment includes a sup...

AI Technical Summary

Problems solved by technology

Because the structural strength of the primary lining is weak, it is not enough to support the advancement of the equipment, and the scheme of using large boots is easy to damage the tunnel of the primary lining during the advancing process, and in the weak area of ​​the tunnel, it is easy to cause partial bursting of the primary lining, which is harmful to the tunnel. some damage
