Embodiment Construction

[0012] The present invention will be further described below.

[0013] In the construction of high-grade highway greening projects, the selection of grass species for slope protection is particularly important. In the past engineering practice, there are many examples of failures caused by improper selection of varieties and species. Therefore, when designing grass species for slope protection, one should first understand the characteristics of local soil, climate, geology and vegetation, and then select grass species and combinations according to design requirements. The selection of grass species and combinations should follow the following principles: ①Ecological adaptability The selected grass species should be suitable for the local ecological conditions. Conditions such as habit, resistance, flat-forming speed, and coverage; ②The principle of well-developed root system, strong stress resistance, drought tolerance, and barrenness tolerance. That is to say, the selected ...

Abstract

The invention discloses a grass lawn for slope protection and the paving method thereof, and aims to provide the grass lawn for slope protection and the paving method of the grass lawn for slope protection, which is applicable to the side slopes of high-grade highways in the mountain areas in Szechwan Basin. The grass lawn for slope protection adopts one of the following four grass seed components (parts by weight) for mixture sowing and planting: 20 shares of high reed fescue, 35 shares of wire grass, 25 shares of curvifoliate india lovegrass, 5 to 10 shares of english ryegrass, and 10 shares of Dutch clover or daghestan sweetclover; 35 shares of high reed fescue, 30 shares of curvifoliate india lovegrass, and 35 shares of Bahia grass; 50 shares of high reed fescue and 50 shares of Bahia grass; 50 shares of high reed fescue and 50 shares of curvifoliate india lovegrass. The paving method thereof comprises the steps as follows: the slope surface is treated, and blocks and sundries on the slope surface are cleaned up, so that the slope surface is smooth; a sward is paved to slope surface in sequence, and then a wooden or bamboo pointed stake is smacked in to fix the sward; the sward is smacked firmly, so that the sward clings to the slope surface firmly; the early curing is performed.

Description

technical field [0001] The invention relates to ecological protection of road side slopes, in particular to a slope protection lawn suitable for high-grade roads in mountainous areas of the Sichuan Basin, and a laying method of the slope protection lawn. Background technique [0002] With the enhancement of people's awareness of environmental protection and the development of grass industry technology, after decades of application and practice, people not only consider the traditional mortar block stone or concrete block slope protection for the slope protection engineering of high-grade highways in our country, but Under certain conditions, more consideration should be given to planting grass to protect the slope. Compared with engineering slope protection, grass planting slope protection has the anchoring effect of deep roots and the reinforcing effect of shallow roots, which can reduce the pore water pressure of the slope body, intercept rainfall, weaken splash erosion, a...
