Embodiment Construction

[0012] As can be seen from Fig. 1 and Fig. 2, a kind of high slope rock-soil anchoring construction method of the present invention, it presets six anchoring points A, B, C, D, E, F according to the anchoring construction scope. 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. When the slope is not too high, points C and D can be merged with points A and B respectively, and only four anchor points are used. 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...

Abstract

The invention is a method and device of slope rock anchoring construction by using cables to pull drill floor for locating and applying pressure. The method: according to the six (or four) anchoring points preset in the range of anchoring operation surface, linking two points in the high position by a steel cable, hanging the drill floor under the pulley rolling on the steel cable through pulley group, using a steel rope fixed on the ground for lifting the jenny to make the drill floor vertically move up and down through the pulley group; using four steel ropes of four transverse moving jennies all fixed on the ground to make the drill floor move left and right through the turning pulleys on the anchoring points and the drill floor. There are four extension and turning truckles on one side of the drill floor, near the steep slope. The anchored driller on the drill floor can regulate the angle of drilling hole on the horizontal and vertical surfaces. When constructing, using operation control button on the drill floor to control to lift the jenny and transverse moving jennies so as to move the drill floor to hole drilling position and make the drill floor closely adhere to the slope, and at the same time support up the supporting legs of the extension and turning truckles to press the drill floor in the hole position for drilling hole.

Description

technical field [0001] The invention relates to a construction method and device, in particular to a high slope rock-soil anchoring construction method and device which are carried out on a high slope by using a cable to pull a drill platform to shift and compress it on a working surface. 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 the instability of the slope soil due to earth-breaking construction, it must be prevented during construction. Or remove a large amount of earth and stone 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 li...
