Problems solved by technology

These slope protection technologies cannot be directly applied to the greening treatment of the dam body, because these methods will cause some damage to the dam body, or affect the safety monitoring of the dam, and bring hidden dangers to the safety of the dam body
In addition, some scholars have proposed some dam slope protection technologies, but these slope protection technologies will cause safety hazards to the dam body. At the same time, it will cost a lot of manpower and material resources to maintain the turf, so it is difficult to popularize and apply

Abstract

The present invention relates to an ecological slope protective apparatus for rock-fill dams and dam slopes and applications thereof, belonging to the field of dam slope protection. A plurality of plant pipes described in the present invention are arranged spaced apart on a dam top and a dam slope, wherein the plant pipes are laid out horizontally, the two ends of the plant pipe being in communication via a fine polyvinyl chloride (pvc) pipe, the pvc pipe acting as a water charging pipe at one end of the plant pipe and acting as a water discharging pipe at the other end of the plant pipe; the plant pipe together with the water charging pipe and the discharging pipe constitute a pipe-net system; one side of the pipe wall of the plant pipe is provided with openings, each section of the plant pipe being in direct connection at the places of the openings, the left and right ports of the plant pipe at the rear end of each pipeline being closable via end lids which are provided with small holes thereon, the aperture of the small holes being equal to the pipe diameter of the water charging pipe or the water discharging pipe, one end being in connection with the water charging pipe, the other end being in connection with the water discharging pipe. The protective apparatus of the present invention greenizes dam bodies and does not impose influence upon the safety of the dam bodies.

Description

technical field [0001] The invention relates to an ecological slope protection device for a rockfill dam crest and slope and an application thereof, belonging to the field of slope protection for a rockfill dam. Background technique [0002] With the development of my country's hydropower industry, more and more high dams will be built in Southwest my country. The environmental damage caused by the completion of the dam has become one of the urgent problems to be solved in the construction of the dam. Although a lot of work has been done on environmental protection while developing hydropower projects, there are still many aspects that need to be resolved urgently. For the upper and lower slopes of the dam abutment, ecological concrete slope protection is mostly used to realize the combination of "hardening" and "greening", but there is no good way to achieve greening for the dam body. As a result, a large area of ​​concrete is exposed in the concrete dam, and a large area...
