Ecological restoration device and restoration method suitable for northern sand excavation river bank zone

Abstract

The ecological restoration device suitable for the northern sand excavation river bank zone comprises a restoration net covering an upper river bank side slope and a pressing and covering mechanism used for pressing and covering the restoration net, the restoration net comprises vertical pipes and transverse pipes which can be bent and wound, and a plurality of connecting pipes are arranged between the vertically-adjacent transverse pipes; a plurality of fixedly connected positioning blocks are arranged at the bottom of the transverse pipe, positioning grooves are formed in the positioning blocks, inserting rods capable of moving up and down are arranged in the positioning grooves, the ends of the inserting rods are sharp, material storage grooves are formed in the inserting rods, plant seeds are stored in the material storage grooves, and the pressing and covering mechanism comprises a walking base, a supporting frame and a pressing and covering roller. By means of the design of the repairing net, the repairing net can be utilized, water and soil loss of the river bank side slope can be effectively prevented, the repairing net can be effectively pressed and covered on the surface of the river bank side slope through the pressing and covering roller in the pressing and covering mechanism, attaching is tighter, and the overall water and soil loss is further prevented.

Description

technical field [0001] The invention relates to the technical field of ecological engineering, in particular to an ecological restoration device and restoration method suitable for the riparian zone of a sand mining river in the north. Background technique [0002] The riparian zone is the ecological transition zone between the terrestrial ecosystem and the aquatic ecosystem. It is a variety of plant belts built along the lakes, streams and valleys. Its main purpose is to keep the water clean and intercept and filter the sediment that may enter rivers and reservoirs. Organic matter, pesticides and other harmful substances. Plants in the riparian zone play an important role. Through the physiological function of plants, not only is it beneficial to the removal of pollutants, but also through the interception of plants, it can effectively slow down the flow rate of runoff and protect the river bank. Research and practice have proved that the coastal buffer zone can effectivel...

Problems solved by technology

In this application, soil erosion prevention is only carried out by covering, which is less effective, and in this device, soil erosion prevention and plant planting are carried out separately, which will make the efficiency of soil erosion prevention low
