Problems solved by technology

These methods generally carry out prismatic concrete or pouring or bricklaying on the slope, and then use perishable and non-degradable materials to make grids. In addition, the matrix soil layer is unreasonable, resulting in low plant survival rate. Once the metal grid partially rots , especially at the top of the slope, so that a large area landslides under the action of its own large weight

Embodiment 1

[0055] Example 1: At the beginning of April 2017, the following operations were carried out on the rock slope of the K7+365-K7+727.6 section of the road connecting the upper and lower reservoirs of the Jinzhai Pumped Storage Power Station in Anhui.

[0056] First, prepare multiple grids 301 made of degradable materials, the grid aperture (maximum size) is 50mm, and each grid has an area of ​​(5*2)m 2 , a batch of 6 pile needles. Carry out operations on sunny days for more than 3 consecutive days in April, clean up the rock face, and divide the rock face up and down into three parts, with a height of 6 meters as a part. One side above the rock face leaves a height greater than the thickness of the solidified layer 2. Then drive the pile eye 302 by the prismatic apex position of 1 meter side length, the pile eye and the base surface just above the rock surface form an angle of about 60 degrees, and the pile eye diameter is 30mm.

[0057] Then the grid is fixed along the rock f...

Embodiment 2

[0065] Embodiment 2: In March 2018, the following operations were carried out on the rock slope of the upper and lower reservoirs of the Jinzhai Pumped Storage Power Station in Anhui Province.

[0066] (1) Prepare a grid 301 made of degradable materials, with a mesh size of 80*80 (mm), and each sheet has an area of ​​(6*1.8)m 2 , a batch of pile needles 6, the tails of the pile needles all have groove fixing parts for binding the grid 301 ropes.

[0067] (2) Choose a sunny day in March to clean up the rock face and piling hole 302. The pile holes 302 are opened on a substantially flat rock surface, and the points of the pile holes 302 are arranged in a rib shape. When driving the pile holes, keep the pile holes and the base surface directly above the rock surface at an angle of 60 degrees. The diameter of the pile holes is 50mm, and the depth is 100mm.

[0068] (3) The grid is fixed along the rock surface by pile needles.

[0069] (4) 100% base soil by mass percentage is use...

Abstract

The invention discloses a rock slope TBS support method which is characterized in that grids made from degradable materials and pile needles are prepared, rock surfaces are cleaned, pile holes are formed, the grids are fixed by the pile needles along the rock surfaces, foundation soil and fertilizers are prepared according to a solidifying layer, a soil layer and a seed layer, corresponding soil and seeds are ejected into the layers, soil slopes are cooperatively stabilized, and daily nursing is implemented. The foundation soil is attached to the surfaces of the slopes, the layers are organically compounded and manually permeated to form high-fixity and high-pelletization vegetation growth fundamental physical environments, the slopes are closed, a reasonable arbor, shrub, herb and ornamental flower slope vegetation community is provided, rapid growth of slope protection plants is ensured, vegetation root systems gradually penetrate the slopes, loss of slope base materials is prevented, rainwater erosion and weathering stripping of the slopes are resisted, moisture and nutrients needed by long-term cycle growth of vegetations are provided in a balanced manner, and construction costs are reduced.

Description

technical field [0001] The invention relates to the technical field of ecological slope protection, in particular to a method for supporting rock slope TBS. Background technique [0002] TBS vegetation slope protection technology is to lay the uniformly mixed thick-layer base material mixture on the rock slope according to the designed thickness. and to improve the ecological environment. Traditional or public slope protection technology mostly adopts the following means, such as the patent announcement number is CN209277102U, a kind of TBS ecological slope protection disclosed, the main points of the technical scheme are that the slope body includes uphill, downhill, placed between uphill and downhill Anchor bars are pre-buried on the upslope, and the upslope surface is provided with a drainage sand cushion, the first geotextile and steel-plastic geogrid in sequence from the inside to the outside, and the anchor bars run through the drainage sand cushion and the first geog...
