Embodiment 1

[0045] In order to overcome the problems of high construction cost, long period, and susceptibility to electric and mechanical failures of the existing mountain access methods, such as figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Figure 6 and Figure 7 As shown, the present embodiment provides a temporary channel erection method suitable for crossing canyons in mountainous areas, including the following steps:

[0046] Step 1, the installation of the anchor system, such as figure 2 shown.

[0047] 1) After clearing the loose layer on the surface of the mountain rock to the complete rock mass 6, mark the position of the anchor hole 7, and use a hydraulic drilling rig to drill without water. After the drilling is completed, use high-pressure air to remove the rock dust and water in the anchor hole 7.

[0048] 2) The anchoring steel bar 5 is driven into the anchor hole 7 and positioned so that the anchoring steel bar 5 is located at the center of the anchor ...

Abstract

The invention provides a method for erecting a canyon-spanning temporary passage applicable to a mountainous area. The method comprises the following steps of 1, anchoring system installation; 2, anchoring region sleeper beam installation; 3, load bearing system installation; 4, bracket load bearing cable erection; 5, catwalk load bearing cable erection; 6, catwalk surface layer pavement. Compared with that of the cableway and temporary bridge erection, the temporary passage erecting method applicable to canyon spanning in the mountainous area has the advantages that the materials are saved, the structure is simple, and the building speed is high. In inconvenient-to-pass regions with scanty materials in mountainous areas in Yunnan, Guizhou and the like, the passing problem can be better solved when the method provided by the invention is used for erecting the temporary passage.

Description

technical field [0001] The invention specifically relates to a temporary channel erection method suitable for crossing canyons in mountainous areas. Background technique [0002] It is inconvenient to cross the canyon area in mountainous areas such as Yunnan and Guizhou. It is usually necessary to build winding roads and then pass through the valley bottom, or pass through cableways across canyons in mountainous areas, or pass through bypass bridges. However, the above method is costly, has a long construction period, is easily affected by electrical and mechanical failures, and is not economical and applicable. Contents of the invention [0003] The purpose of the present invention is to overcome the problems of high construction cost, long cycle and easy to be affected by electric power and mechanical faults in the existing mountain pass method. [0004] For this reason, the present invention provides a kind of temporary passage erecting method that is applicable to mou...
