A crawler type segment secondary lining equipment

Abstract

The invention discloses a crawler-type segment secondary lining equipment, which includes a main body frame, a steel support frame similar to the segment section is arranged at the front end of the main body frame, and a plurality of squeezing frames are evenly distributed on the support frame. Oil cylinder, the squeeze oil cylinder corresponds to the lining segment, a segment assembly machine is arranged on the main body frame, a walking crawler type walking chassis is arranged under the main body frame, and the segment assembly machine is located on the main body frame A plurality of locking devices are arranged at the rear, and the locking devices are used to lock the entire equipment during segment assembly and unlock when the entire equipment is walking. During the propulsion process of the present invention, as the squeeze cylinder advances against the segment, the caterpillar moves synchronously, and can provide the reaction force required for the squeeze cylinder to tighten the segment, ensuring the force acting on the segment during the advance process. Keep it large enough and stable, and the locking between equipment segments adopts self-anchor locking and squeeze oil cylinders to work together, which further ensures the quality of segment lining.

Description

Technical field [0001] The invention relates to a lining equipment, in particular to a crawler-type segment secondary lining equipment. Background technique [0002] With the increasing application of shield tunnels, from the early road and railway tunnels to today's subways, cables, water intake and drainage channels, etc. The diversified application of tunnels makes the structural strength, service life and waterproof ability of tunnels have higher requirements. Excavation of tunnels in relatively small areas is usually not suitable for shield machine operations. Open excavation, undercut excavation and cover excavation are often adopted. These methods are often reinforced by reinforced concrete to strengthen the excavated tunnel and reinforced concrete. The tunnels often have poor waterproof performance and weak structural strength. This requires secondary lining of the tunnel segments to meet the special requirements of the tunnel. [0003] The existing segment secondary lini...

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
