Problems solved by technology

Compared with the existing technology, this technology is not complicated. From the perspective of construction technology, it does not need to use large-scale mechanical equipment to transport a large amount of materials; from the perspective of time, except for winter construction, the basic functions can meet the design requirements in about 3 months; from the perspective of project cost It is only 1 / 10~1 / 3 of the existing technology; and from the perspective of ecological benefits, it is incomparable to the existing technology

Embodiment

[0032] For the treatment of the slope on the left bank of the Youjiang River in the Baise Water Conservancy Project in Guangxi, it was originally planned to adopt the masonry scheme for slope protection. In March 2002, after introducing the technical scheme to the owner——Guangxi Baise Youjiang Company and Guangxi Water Conservancy and Electric Power Survey and Design Institute, the design institute revised the design with us: the slope protection section 120-123m elevation adopts traditional masonry slope protection, 123-132m elevation adopts our "new technology" slope protection, area: 3240m 2 .

[0033] The construction started on May 25, 2002 and was completed on June 11. The period from June 12 to August 11 is the professional maintenance and management period; the plants are equipped with four types of vetiver, barnyardgrass, bahia grass and wedelia. The basic fertilizer for nutrient supply is Vetiver No. 1 and No. 2 fertilizers; at the same time of construction, seven 1...

Abstract

The present invention relates to the embankment protection in water conservancy and hydroelectric power system, especially inner slope in water reservoir. The plant configuration and ecological engineering technology of the present invention is superior to traditional concrete, laid stone wall, anchor pile and other traditional rigid means, which are lack of ecological effect of purifying water and lasting effect, and superior to available biological engineering means with non ideal effect. The present invention is one ecological engineering technology with vetiver as main body and other plant variety, and has superior ecological effect, lasting slope protection effect, low cost and simple construction process.

Description

technical field [0001] The present invention relates to rivers, lakes, reservoirs and power stations in water conservancy and hydropower systems for beach fixing and dike protection, anti-scour and bank revetment, danger relief and reinforcement, as well as anti-slip slope protection and soil-fixing and water conservation for excavated slopes in engineering construction, especially for reservoir water level fluctuations The inner slope of the belt. Background technique [0002] In the protection of rivers, lakes and reservoir embankments, existing technologies all adopt traditional steel technical measures such as concrete, masonry stone retaining walls or anchor piles. This kind of "hardening" measures obviously lacks ecological benefits, reduces the self-purification ability of the water body, and it is difficult to guarantee a lasting effect. In the past, bioengineering measures to control water and soil erosion have also been carried out on the slopes of river reservoir...
