Problems solved by technology

[0003] The rock mass on the slope surface is relatively broken due to the engineering excavation of the slope, and sunken grooves or sunken pits are often formed on the slope surface, resulting in the exposure of a large number of rock slopes and destroying the surrounding ecological environment. Potholes are often cumbersome to repair, often time-consuming and costly
Especially for some arid areas or areas where water diversion is difficult, it is difficult to carry out ecological restoration of slopes by conventional methods

Embodiment Construction

[0031] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0032] like Figures 1 to 3 As shown, a phosphogypsum-based vegetation blanket for rapid greening of multi-hole slopes includes a whole piece of vegetation blanket 4 laid in the pit 2 of the slope 1, and the vegetation blanket 4 includes a filling layer from bottom to top 4.1. The water bag layer 4.2 and the plant growth layer 4.3. The anchor 5 can be inserted into and penetrates the inside of the filling layer 4.1, the water bag layer 4.2 and the plant growth layer 4.3. The anchor 5 is hollow inside and has a communicating hole 5.1 on its surface.

[0033] Further, a hollow cavity 5.2 is opened inside the anchor 5, and the top of the hollow cavity 5.2 is open, and a cover 5.3 matched therewith is provided. By setting the cover 5.3, it is possible to prevent the water from directly and rapidly leaking from the top of the anchor 5 whe...

Abstract

The invention discloses a phosphogypsum-based vegetation blanket for rapid greening of a multi-pit slope surface and a construction method of the phosphogypsum-based vegetation blanket. The phosphogypsum-based vegetation blanket comprises a whole vegetation blanket body laid in pits of a slope, the vegetation blanket body sequentially comprises a filling layer, a water bag layer and a plant growth layer from bottom to top, ground anchors can be inserted into and penetrate through the filling layer, the water bag layer and the plant growth layer, and the insides of the ground anchors are hollow, and communicating holes are formed in the surfaces of the ground anchors. According to the invention, rapid greening and ecological restoration can be carried out on the uneven multi-pit slope surface.

Description

technical field [0001] The invention relates to the technical field of slope ecological restoration, in particular to a phosphogypsum-based planting blanket for rapid greening of slopes with many pits and a construction method thereof. Background technique [0002] Engineering construction inevitably changes the surface structure and destroys vegetation. The fragile ecosystem is further strongly disturbed, and soil erosion is intensified. Large-scale excavation of earth and rocks leads to the exposed slope surface, forming an artificial primary bare land, and the degradation of the ecosystem is extremely prominent. If appropriate ecological restoration measures are not taken, the ecological self-recovery process of exposed slopes, especially rocky slopes, will be very long, which will cause long-term and severe water and soil erosion, slope collapse and other problems, which will seriously endanger the safety of the project and the surrounding area of ​​the disturbance area. ...
