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.

The invention provides a high and steep slope vegetation recovery structure. The surface layer of a high and steep slope body is covered with a growth substrate; a reinforced mesh is positioned in the growth substrate; water-blocking grooves are horizontally distributed in the growth substrate; a seed germination substrate is longitudinally embedded in a strip shape into the growth substrate; seed germination holes are distributed in microporous thin films according to the position of the seed germination substrate; the surfaces of the growth substrate and the seed germination substrate are covered with the microporous thin films in a fitted manner; the microporous thin films are clung to the bottoms of the water-blocking grooves at the water-blocking grooves. The slope substrate of the recovery structure is stable; soil or broken stones on the slope surface are effectively prevented from sliding off; the recovery structure is light in self weight, thereby facilitating the fixation of a greening substrate, increasing the germination rate of seeds and increasing the cover degree of vegetation; the water-blocking grooves are capable of prolonging the retaining time of the moisture from natural rainfall or manual watering on the microporous thin films to further enable the moisture to penetrate the growth substrate, thereby avoiding the runoff loss under the high and steep slope condition and the erosion of the runoff on the growth substrate or the seed germination substrate.

The disturbed reinforcement structure and construction method of existing bridges in deep valleys can effectively solve the problems of deformation and stability reinforcement of high-pier long-span bridges in steep slopes and valleys after disturbance, and has the characteristics of good economy, convenient construction, and environmental protection. The reinforcement structure includes: supporting pile foundations and supporting beams. The supporting pile foundations are arranged at intervals in the valley corresponding vertically to the foundation of the reinforced bridge abutment. The supporting beams are fixedly connected to the top of each supporting pile foundation, and their front ends are in close contact with the reinforced bridge abutment. , the rear end extends into the stable bedrock of the valley slope on the corresponding side of the reinforced bridge abutment; the reinforcement piles and soil retaining plates are arranged at intervals on the lower side of the valley in the influence range of the reinforced bridge abutment foundation, and the soil retaining plates are set at intervals Between the reinforcement piles and facing the upstream side of the valley; the waste muck body and the sealing layer, the waste muck body is filled in layers in the valley inside the reinforcement piles and the retaining plate, and the sealing layer is constructed on the top surface of the waste muck body.
