Embodiment Construction

[0012] From Figure 1, figure 2 It can be seen from the figure that the present invention is a high-slope rock-soil anchoring construction method, which presets six anchoring points A, B, C, D, E, and F according to the scope of anchoring construction. Among them, the two high points A and B should be a distance higher than the work area, preferably on the mountain ridge, which is convenient and reliable for construction; the two low points E and F are required to be lower than the lowest position of the operation, and can be placed on the On the ground, after the two points C and D in the middle are anchored by the two points A and B on the height, select the location and fix it. An anchor point steering pulley 7 is respectively housed on the four anchor points C, D, E, and F in the middle and low places. Use a thicker steel wire rope as the main steel cable 1, firmly fix its two ends on the two anchor points on the high place, and install the anchor drilling rig 11, hoisting...

Abstract

The present invention is high slope rock and soil anchoring construction method and apparatus. The construction method includes presetting six anchoring points within the anchoring construction range, connecting two upper anchoring points via a steel cable; suspending drilling table via a pulley block under one suspended pulley rolling on the steel cable; connecting four transversely shifting winders fixed on the ground to other four anchoring points separately via four steel cables via the pulley; and operating the winders for the drilling table move vertically and transversely while closing to slope. The anchoring drilling machine on the drilling table can regulate its drilling angle in both vertical direction and horizontal direction. The construction method and apparatus of the present invention is practical, safe and reliable.

Description

technical field [0001] The invention relates to a construction method and device, in particular to a method and device for rock-soil anchorage construction on high slopes. Background technique [0002] We know that landslides are a common problem during road construction and building construction. For large landslides, we still avoid it for the time being. However, for landslides that may be caused by slope soil instability due to dynamic construction, they must be prevented during construction. Or remove a large number of upper stones to reduce the slope and stabilize it, or use anchor rods and anchor cables to penetrate the dangerous slip surface for anchoring. Therefore, we must carry out geotechnical anchoring construction on the hillside. If the hillside is not too high, we can set up scaffolding or use large lifting equipment to lift the anchor drilling rig up the hillside for construction. This is difficult when the hillside is high: scaffolding that is too high i...
