Plant brick and railway bed slope greening method

Abstract

The invention discloses a plant brick and a railway bed slope greening method. The plant brick comprises a matrix block and grasses growing on the matrix block for more than one life cycle, where grass roots form a root net in the matrix block. The method is characterized by utilizing the plant brick for greening a railway bed slope. By utilizing the characteristic that developed fibrous root systems of the grasses grow disorderly, a soil matrix is fully wrapped and wound so as to be fixed, so that a geometry with a fixed root form is obtained. Through building a grass root soil environment, the grasses are bred for one life cycle, the root systems can be organically connected, an original substrate can be carried, and the scattering is avoided during a transporting process. According to the railway bed slope greening method provided by the invention, the planted plants are utilized for greening, i.e. the plants for greening are planted in advance, and the plants with the complete rootsystems are used for greening, so that a greening effect is better.

Description

Technical field [0001] The invention belongs to the field of ecological protection, and relates to road side slope maintenance technology, in particular to an ecological brick, and a method for using the ecological brick to green the side slope of a railway roadbed. Background technique [0002] The slope protection of railway subgrade mainly includes plant protection and engineering protection. The methods of plant protection include: planting grass, laying turf, and planting trees. Engineering protection methods include sash protection, cover, protective wall, dry rubble slope protection, mortar rubble slope protection, mortar prefabricated block slope protection, anchor steel wire mesh shotcrete, sprayed concrete slope protection, etc. [0003] The Lhasa-Nyingchi section of the Sichuan-Tibet line is located in the southern Tibet valley and alpine valley on the edge of the Qinghai-Tibet Plateau, compared with the former Qinghai-Tibet line and Lari line. It is an area with extreme...

AI Technical Summary

Problems solved by technology

[0006] 1. The side slope of the railway embankment is a slope. During the sprinkling process, the soil in the hollow brick is seriously lost under the erosion of water, and the upper part of the hollow brick has a "flat head", that is, there is a hollow in the upper space of the hollow brick, and the soil volume is reduced, which affects the greening of the slope. quality and effect

[0007] 2. Due to the special geographical conditions of the Qinghai-Tibet Plateau, the time for greening construction in a year is only about one month. The construction period is too short, which seriously affects the progress of the greening project. In order to adapt to the acceptance progress of the overall project, it is necessary to increase manpower and material resources input

[0008] 3. Through the design and use of the drip irrigation system, the vegetation restoration effect has been improved, but the equipment and facilities construction of the drip irrigation system has increased the investment in equipment costs and labor costs
