A pile-net flexible cable barrier structure includes a first V-shaped pile, a second V-shaped pile, a left tension pile, a right tension pile, a first flexible cable net disposed between the left tension pile and the first V-shaped pile, a second flexible cable net disposed between the first V-shaped pile and the second V-shaped pile, and a third flexible cable net disposed between the second V-shaped pile and the right tension pile. A second pile body of the first V-shaped pile are disposed parallel to a third pile body of the second V-shaped pile, openings of the first V-shaped pile and the second V-shaped pile face a same side, the left tension pile are disposed parallel to the first pile body of the first V-shaped pile, and the right tension pile are disposed parallel to the fourth pile body of the second V-shaped pile.

Pile-net flexible cable barrier structure and construction method thereof

A recyclable inclination measuring device includes measuring units arranged in a linear array during installation, and two adjacent measuring units are eccentrically hinged by a joint; during the measurement, measuring units are arranged in a Z shape in the measuring tube, the inner wall of the measuring tube is closely attached to the joint, and measuring units extending out of the measuring tube are folded and arranged. the present invention adopts a recyclable inclination measuring device with the above structure, during the measurement, it is placed in the measuring tube, which can be arranged in a Z shape under the action of gravity, and then it can be measured with the synchronous rotation of the measuring tube, when it is recovered, it only needs to be pulled out, which reduces the difficulty of recovery and improves the recovery efficiency.

Recyclable inclination measuring device

A barrier structure for bearing a high-energy impact and construction method thereof are provided. The barrier structure includes a supporting pile array arranged between two opposite mountain slope surfaces. The supporting pile array is arranged in a straight line and includes two or more supporting piles. The two or more supporting piles are fixed at a lower part of a mountain. A barrier net is connected to the two or more supporting piles. The barrier net passes through the supporting pile array and extends to the two opposite mountain slope surfaces. The barrier net is fixed on the two opposite mountain slope surfaces. Pull plates are disposed on the two opposite mountain slope surfaces, and one side of each of the pull plates is fixed to a corresponding slope surface of the two opposite mountain slope surfaces through reverse prestressed anchor cables.
