A method for protecting slope vegetation by using plant fiber blanket

Abstract

The invention relates to a method for protecting slope vegetation through plant fiber blankets. The method for protecting slope vegetation through plant fiber blankets is applicable to fill roadbed slope protection during a construction period. According to the method, fill roadbed slopes are divided into two categories, according to one category, the fill roadbed slopes are formed slopes where roadbed filling is completed, and according to the other category, the fill roadbed slopes are non-formed slopes where roadbed filling is not completed. The operation that roadbeds are gradually filled and spreading is performed layer by layer is performed on the non-formed slopes, the plant fiber blankets are fixed, after filling of the all the roadbeds and covering of the plant fiber blankets are completed, plant seeds are sown on the surfaces of the plant fiber blankets, covering of thin soil is performed, and watering and curing are performed so that vegetation can be formed; the operations that grass seeds are sown on the total slopes, then the total slopes are covered with the plant fiber blankets, and curing is performed are adopted so that the vegetation can be built. By means of the method, the slopes can be greened as soon as possible, water and soil loss can be effectively controlled in the construction period, and the effectiveness of slope protection is enhanced in the construction period.

Description

technical field [0001] The invention relates to a biological protection method for road slopes in the field of road slope protection, in particular to a method for using plant fiber blankets to protect slope vegetation. Background technique [0002] Water and soil erosion control of road embankment slopes has always been the focus and difficulty of environmental protection during highway construction. The soil disturbance range is large and the soil is loose during the construction period. In many places in my country, the construction period is in the same period as rain and heat. This objectively causes The soil erosion modulus during the construction period is very large, which often leads to huge damage to the surrounding farmland water conservancy facilities, causing rivers, lakes and reservoirs to be silted up by the lost soil in a short period of time, seriously affecting the functions of various water conservancy facilities. play. Therefore, management departments suc...

Problems solved by technology

[0019] Still another object of the present invention is to provide a new method of using plant fiber blankets for slope vegetation protection, which can fill a layer of roadbed, cover and green a layer of slope, the technical problem to be solved is to make It can also build vegetation in real time during the subgrade filling process, and set up a water retaining wall on the side of the subgrade above the slope, and set up a longitudinal temporary rapid flow trough on the slope surface to effectively remove rainwater from the road surface and prevent runoff from the road surface. The erosion caused by the surface, while avoiding the pollution of the road surface construction water and operating materials to the slope surface, to achieve effective greening and beautification of the slope surface, so as to provide all-round and whole-process slope protection during the roadbed filling process, so as to be more suitable practical
