Scaffold for lining defect renovation construction in operation tunnel

Abstract

The invention belongs to the field of buildings, and particularly relates to a scaffold for lining defect renovation construction in an operation tunnel. Comprising a hydraulic oil cylinder, a scaffold pedestal, vertical rods, transverse rods, inclined struts and a three-dimensional connecting mechanism, the hydraulic oil cylinder is fixedly arranged on the lower end face of the scaffold pedestal, two rows of annular clamping grooves are longitudinally formed in the upper end face of the scaffold pedestal, and short steel rods are arranged in the annular clamping grooves; the vertical rods are inserted into gaps formed by the annular clamping grooves and the short steel rods, and the vertical rods, the transverse rods and the inclined struts are connected through a three-dimensional connecting mechanism. The three-dimensional connecting mechanism is composed of a vertical connecting assembly, a transverse rod connecting assembly and an inclined rod connecting assembly. A circular level bubble is embedded in the geometric center of the upper end face of the scaffold pedestal. The hydraulic oil cylinder is arranged to adjust the height of the scaffold in the tunnel, and the three-dimensional connecting mechanism is arranged to fix the vertical rods, the transverse rods and the inclined struts and quickly lock and fix the vertical rods, the transverse rods and the inclined struts.

Description

technical field [0001] The invention belongs to the field of construction, and in particular relates to a construction scaffold for rectifying lining defects in an operating tunnel. Background technique [0002] Operating tunnel construction skylights have a tight construction period and short time, and long and large tunnel defect remediation construction can effectively utilize the time. At present, the tunnel defect remediation construction commonly uses disk-type and bowl-type scaffolds, but there are many rods for this type of scaffolding. The process is cumbersome, time-consuming and labor-intensive, the utilization rate of a single skylight is low, and the construction cost increases. [0003] On-site construction mostly uses portal scaffolding as operating equipment, but for the convenience of loading and unloading, the portal scaffolding rods are mostly Φ26.8mm, Φ42mm steel pipe members, and the height of the large-section tunnel defect repair construction is mostly...

Problems solved by technology

[0002] The construction period of the skylight in the operation tunnel is tight and the time is short. The construction of long and large tunnel defects can make effective use of the time even tighter. At present, the ring-type and bowl-type scaffolds are commonly used in the construction of tunnel defect repair. However, there are many rods for this kind of scaffolding. The process is cumbersome, time-consuming and labor-intensive, the utilization rate of a single skylight is low, and the construction cost increases

[0003] On-site construction often uses portal scaffolding as operating equipment, but for the convenience of loading and unloading, portal scaffolding rods are mostly steel pipe members with specifications of Φ26.8mm and Φ42mm, and the height of scaffolding for repairing defects in large-section tunnels is mostly 6-8m, and the overall stability of the scaffolding Construction operations such as drilling, chiseling, and grouting (injecting) will cause large shaking, which will affect the safety of construction personnel and construction efficiency
