specific Embodiment approach

[0027] A fast installation system for super-long and large-inclination tunnel anchor steel rods, such as figure 1 As shown, it includes a hole platform 1 composed of section steel, and a 10t load-bearing rope hoist 2 and a 5t traction hoist 3 are installed at the rear of the horizontal hole exit platform 1; the load-bearing rope hoist 2 is mainly used for hoisting and auxiliary transportation of steel tie rods , the main function of the traction hoist 3 is to transport the steel pull rod; a rope limiter 5 is installed at the end of the platform. damage;

[0028] At the bottom of the hole far above the platform, two guide wheels 4 are set, which function to turn the load-bearing rope and the traction rope 12; a double-door block 6 is installed at the top of the hole between the guide wheels and the platform, and the steel rope will pass through. pulley for construction;

[0029] At the bottom of the tunnel anchor hole, an anchor point 7 is set near the bottom, and the angle o...

Abstract

The invention discloses a system for fast mounting a steel pull rod in ultra-long and large-dip-angle tunnel anchorage by means of a transverse gallery of a tunnel and an operation method. The operation method is characterized by comprising the following steps: (1) building of a platform; (2) arrangement of a traction system; (3) hoisting and transportation of the steel pull rod; (4) mounting of the steel pull rod. Due to large length, narrow space and a large dip angle in ultra-long and large-dip-angle tunnel anchorage, the steel pull rod is difficult to mount. With the adoption of the system and the operation method, the steel pull rod can be mounted in site smoothly and fast in the ultra-long and large-dip-angle tunnel anchorage by means of the transverse gallery of the tunnel; fewer materials are required, the structure is not complicated, the transportation distance is shortened, and the mounting efficiency is improved; the system is stable on the whole, and safety accidents are not prone to occur.

Description

technical field [0001] The invention relates to the field of civil engineering, in particular to a system and an operation method for realizing fast installation of anchor steel tie rods in super-long and large-inclination tunnels. Background technique [0002] At present, the installation of domestic suspension bridge tunnel anchorage system mostly adopts the arrangement of traction system at the entrance of the tunnel, transports it to the installation location, and installs it. This method has long traction distance, slow transportation and low efficiency. If the present invention is adopted, the transverse hole of the tunnel can be effectively used, the traction device is simple, and the traction distance is greatly reduced, so that the transportation rate is increased, the installation speed is also increased, the cost is greatly saved, and the construction period is shortened. Contents of the invention [0003] The purpose of the present invention is to provide a fa...
