Problems solved by technology

The central plains and northern regions mainly live on wheat straw, and due to the characteristics of the northern weather and farming habits, wheat straw is seldom recycled, but directly burned, which is a waste of resources and pollutes the atmospheric environment
Agriculture in the south is mainly based on rice straw. With the economic development of the southern region today, many parts of rice straw are no longer used as fuel, but are piled directly in the field and allowed to rot freely. This non-standard disposal method, Also brought harm to the environment, but also caused a waste of resources

Embodiment 1

[0018] Cut the dried rice straw obtained from Jiangning, Nanjing into pieces with a length of 2-3 cm, soak it in hot water at 98°C for 6 hours, dry the pretreated rice straw, keep the moisture content at 15%, and add 5% of environmental protection Hydrophobic agent (specification brand: LS-1001, manufacturer: Shanghai Ziheng Material Technology Co., Ltd.), sizing MDI, the glue amount is 8%, the hot pressing process is: temperature 150 ° C, hot pressing time 6 minutes and hot pressing Compression pressure 3MPa, compression density 0.6kg / cm 3 . The formed slope protection brick has a thickness of 3.5cm and two circular holes in the middle. The construction process is carried out according to the traditional ecological slope protection construction technology. The original slope protection base 1 is leveled, the hardened layer 2 is laid, and the soil layer 3 is laid. The hardened material stone is 10cm thick, and the soil layer is 30cm thick. Willows and calamus are planted in ...

Embodiment 2

[0020] Cut the dried rice straw obtained from Jiangning, Nanjing into pieces with a length of 5 cm, and soak it in hot water at 98°C for 2 hours. After the pretreated rice straw is dried, the moisture content is 5%, and 3% of an environmentally friendly hydrophobic agent is added. (Commercial tung oil, place of origin: Zigui County, Hubei Province), sizing MDI, the glue content is 15%, the hot pressing process is: temperature 180 ° C, hot pressing time 20 minutes and hot pressing pressure 5 MPa, pressing density 0.9kg / cm 3 . The formed slope protection brick has a thickness of 3.5cm and four circular holes in the middle. The construction process is carried out according to the traditional ecological slope protection construction technology. The slope protection is leveled, and the hardened materials and soil layers are laid. The hardened material waste concrete is 30cm thick, and the soil layer is 50cm thick. On the straw base, ecological slope protection bricks are laid, and ...

Embodiment 3

[0022] Cut the dried rice straw obtained from Jiangning, Nanjing into pieces with a length of 0.5 cm, soak it in hot water at 98°C for 2 hours, and dry the pretreated rice straw with a moisture content of 10%, add 1% of environmentally friendly (commercial tung oil, place of origin: Zigui County, Hubei Province), sizing MDI, glue amount is 1%, hot pressing process is: temperature 120 ℃, hot pressing time 5 minutes and hot pressing pressure 2MPa, pressing density is 0.4kg / cm 3 . The formed slope protection brick has a thickness of 3.5 cm and a circular hole in the middle. The construction process is carried out according to the traditional ecological slope protection construction technology. The slope protection is leveled and hardened materials are laid, and the soil layer is laid. The hardened material broken bricks are 20cm thick, and the soil layer is 40cm thick. Willows and calamus are planted in the holes of the slope protection bricks, and ryegrass is sown on the other...

Abstract

The present invention provides a method for constructing ecological revetment by utilizing agricultural wastes plant residual body which can slowly release nutrients and can be bio-degraded. Said construction method includes the following steps: selecting material, utilizing thermal-process to decolor, hydrophobic modification, bonding, hot-pressing and forming, making ecological revetment brick and laying the ecological revetment bricks on the revetment.

Description

1. Technical field [0001] The invention belongs to a side slope or slope stabilization technology, in particular to a construction method of plant residue-based ecological slope protection. 2. Background technology [0002] Existing technology: With the rapid development of my country's economy, the problems of water environment and water ecology have become increasingly prominent, and the amount of new roads has increased day by day, and the amount of slope protection construction has increased year by year. However, at present, the slope protection of many rivers, ditches, dams and roads Using hardened brickwork, this fully hardened brickwork destroys the natural ecosystem of the original slope and reduces biodiversity. In water conservancy projects and urban construction, it is an effective method to use concrete slabs and blocks for protection. However, on the large-area rigid protection surface made of concrete slabs, there is no grass, it is barren, and the natural envi...
