Desertification region railway sandstorm plane micro-seepage drip irrigation system and construction method thereof

Abstract

The invention relates to a desertification region railway sandstorm plane micro-seepage drip irrigation system and a construction method thereof. The system performs micro-seepage drip irrigation on plants in sandstorm plane protection regions at two sides of a desertification region railway, and the plants are planted in checks constructed in the regions. The system comprises a main pipeline, secondary pipelines and tail end pipelines, the main pipeline is connected with the plurality of secondary pipelines, the secondary pipelines are laid in the checks and penetrate through the checks in columns, the secondary pipelines are connected with the plurality of tail end pipelines in each check, and drip irrigation holes are formed in the pipe walls of the tail end pipelines. The system has the advantages of being high in automation degree, capable of saving water sources and investment, capable of protecting the ecological environment, high in greening effect taking, good in greening effect and low in later-period maintenance, is suitable for construction of a desertification region railway sandstorm plane protection system, and is also suitable for the fields of roads, municipal administration and the like.

Description

technical field [0001] The invention relates to the technical field of wind and sand protection, in particular to a micro-seepage drip irrigation system and a construction method for railway wind and sand planes in desertification areas. Background technique [0002] In the northwest and southwest regions, many railways pass through desertified areas, where the average annual evaporation is much greater than the rainfall, the surface covering soil is barren or even exposed rocks, and the growth conditions of plants are poor. As a linear project, the construction of railway projects is bound to affect The surrounding fragile ecological environment has a greater impact. With the change of the original ecological micro-landform, the existing ecological system composed of the original soil, water, wind, plants and other elements is destroyed. At the same time, due to the slow growth of plants in desertification areas, If left untreated, the desertification around the railway wil...

AI Technical Summary

Problems solved by technology

[0002] In the northwest and southwest regions, many railways pass through desertified areas, where the average annual evaporation is much greater than the rainfall, the surface covering soil is barren or even exposed rocks, and the growth conditions of plants are poor. As a linear project, the construction of railway projects is bound to affect The surrounding fragile ecological environment has a greater impact. With the change of the original ecological micro-landform, the existing ecological system composed of the original soil, water, wind, plants and other elements is destroyed. At the same time, due to the slow growth of plants in desertification areas, If left untreated, the desertification around the railway will change from dotted to patchy. If left unchecked, it will even cause sand accumulation on the railway, which threatens the safety of railway operation and prevents the establishment of a new ecological balance between the railway and the ecology.

[0003] When the railway passes through a desertified area, according to the level of wind and sand, a certain width of wind and sand plane protection works is often built on the windward side and the leeward side, so as to play the role of sand blocking, sand fixation, and reduce the amount of sand transport, while improving the surrounding fragile ecological environment. However, due to the difficult plant growth environment, even if drought-resistant and barren-resistant plants are used, they still face the practical problems of slow growth and low survival rate. Under natural conditions, there may be fragmented and isolated plant growth in a large area. , can not fully play the original idea of ​​the wind and sand corridor effect

[0004] During the maintenance of the original wind-blown sand plane protection plants, due to the difficulty of water intake, the cost of watering is relatively high. At the same time, due to the artificial watering method, while the plants cannot be fully covered, a large amount of water resources are wasted, which further exacerbates the relationship between water shortage and waste of water. contradiction
