Embodiment 1

[0034] A step-shaped ecological slope protection structure in the water-fluctuation zone of the reservoir area, characterized in that:

[0035] On the slope on the water-fluctuating zone, a number of concreted horizontal terraces 2 are arranged. There is a primary slope 1 between adjacent horizontal step surfaces 2 . The vertical height difference between two adjacent levels of horizontal steps 2 is 2 to 3 meters, and the width of the surface of the horizontal steps 2 (the depth from far away from the side slope to close to the side slope) is 0.7 to 1.0 meters.

[0036] A concrete prefabricated tension beam 5 is arranged at the lower end of each grade of slope 1 . The lower part of the concrete prefabricated tension beam 5 is in contact with the horizontal step surface 2 . The concrete prefabricated tension beam 5 has several anchor holes for anchor rods 6 to pass through. The concrete prefabricated tension beam 5 is fixed by inserting the anchor hole and driving the anchor...

Embodiment 2

[0042] This embodiment is directed to the implementation method of a step-shaped ecological slope protection structure in the water-fluctuating zone of the reservoir area described in Embodiment 1, which is characterized in that it includes the following steps:

[0043] S1: Cleaning of the side slope of the water-fluctuation zone: Slope cutting and cleaning of the broken rock and soil mass on the surface of the side slope of the water-fluctuation zone in the reservoir area.

[0044] S2: Prefabricate several sections of concrete beams, each section is 5 meters long. Prefabricated vegetation-type porous concrete prefabricated module 3. The section of the concrete beam is rectangular, the height is 0.2-0.25m, and the width is 0.2-0.25m

[0045] S3: Construction of horizontal steps 2: build a horizontal step 2 at a certain height on the rock-soil slope, and the rock-soil slope 1 is between adjacent horizontal steps. The horizontal platform step 2 is formed on the rock-soil slope...

Abstract

The invention provides a stepped ecological slope protection structure for a water-level-fluctuating zone and an implementing method thereof. A vegetation slope-protection technology and an engineering slope-protection technology are combined, and the advantages of the vegetation slope-protection technology and the engineering slope-protection technology are exerted. On the one hand, with growingof plants, small cracks occurring due to the hard reinforcing measures can be covered to a certain extent, and thus the situation that the small cracks are scoured by waves and hollowed out, and consequently, larger and larger holes are formed is prevented; and on the other hand, the anti-scouring capability of the hard measures can further provide protection for matrixes on which vegetation grow.According to the stepped ecological slope protection structure for the water-level-fluctuating zone and the implementing method thereof, the stability of rock and earth mass in the water-level-fluctuating zone is ensured, the vegetation in the water-level-fluctuating zone is further recovered, and harmony and unity of human activities and the natural environment are achieved.

Description

technical field [0001] The invention relates to the technical field of geotechnical slope protection, in particular to a step-shaped ecological slope protection of a water-fluctuation zone in a reservoir area and an implementation method thereof. Background technique [0002] With the successful water storage and operation of the Three Gorges Dam and other water conservancy projects, due to natural factors or reservoir scheduling and other reasons, the water level of the reservoir will fluctuate within a range of tens of meters or even tens of meters, forming areas where the reservoir area is periodically submerged and exposed to the water surface. It is called the water-fluctuation zone of the reservoir area. In some areas with relatively large slopes, rapid water flow, and severe wave erosion, the vegetation in the water-fluctuation zone is easily destroyed, forming a bare area, which accelerates the deterioration of the geotechnical properties of the water-fluctuation zon...
