Description

Technical Field

[0001] The invention belongs to the technical field of tunnel side wall construction equipment, and in particular relates to a device and method for constructing circular arc chamfering of a deep hole tunnel side wall. Background Art

[0002] One of the arc chamfering construction equipment for deep hole tunnel side walls is the tunnel lining trolley, which is mainly used for concrete pouring and forming in tunnel lining construction. It uses the template system to line the tunnel side walls, vaults and floor plates as a whole or in sections to ensure the stability and surface flatness of the tunnel structure. In the construction of arc chamfering of the side walls, the template of the lining trolley can be customized according to the design requirements to form a specific arc chamfer shape; the lining trolley is usually composed of a walking system, a template system, a support system, a hydraulic system and a vibration system.

[0003] In the Chinese patent with publication number CN118601617A, an intelligent tunnel lining trolley and a construction method thereof are mentioned...; In the intelligent tunnel lining trolley, when the lifting part acts downward to lift the track through the traveling assembly, the lifting part simultaneously applies a force to the pulling part, and the pulling part and the traveling assembly synchronously lift the track, thereby reducing the force on the traveling assembly, thereby reducing damage to the traveling assembly and increasing the service life of the traveling assembly; When the existing tunnel lining trolley for arc chamfering construction of tunnel side walls is in use, the vibration system is installed on the inner side of the formwork, and when in use, the vibrating rod is started and reciprocatedly inserted into the concrete poured on the outer side of the formwork, so as to discharge the air contained in the concrete. However, during the reciprocating insertion and vibration process, part of the concrete slurry will be brought out with the vibrating rod and flow to the inner side of the formwork. The overflowed mortar forms a local bonding layer after drying, which makes it difficult to separate the formwork from the concrete. Frequent manual cleaning of the inner side of the formwork is required, which seriously affects the construction efficiency and may even damage the surface accuracy of the formwork. In addition, during the vibration process, the vibrating rod can only pass through the rectangular groove to vibrate the concrete in a partial area, thereby limiting the vibration range.
