Abstract

The invention discloses a positioning and buckle system on a net frame for restoring the topsoil of a mountain desert steppe degraded grassland. The net frame includes a fixing pile and a filter screen assembly that can be separated from each other. The bracket is used to quickly and easily fix the fixed pile on the ground, and does not hinder the storage and transportation of the fixed pile; the filter screen assembly includes a screen main body and two connecting columns respectively arranged at both ends of the screen main body, the two The main body of the filter screen can be wound around each connecting column, so that the distance between the two connecting columns can be adjusted. On the fixing pile, there are mounting holes for accommodating the connecting columns along the vertical direction. The buckle system includes a hole plug, and the hole plug is used to be fastened at the opening of the installation hole in which the connection post is built, so that the connection post and the installation hole are fixedly connected.

Description

technical field

[0001] The invention relates to the technical field of topsoil reconstruction and vegetation restoration of degraded grasslands, in particular to a positioning buckle system on a net frame for restoring topsoil of degraded grasslands in mountainous desert grasslands. Background technique

[0002] Grassland degradation and windbreak and sand fixation have always been a worldwide problem. For my country, the severity of windbreak and sand fixation is even more serious. Although my country has a vast land area, the desertification area is actually too large. People are doing their best to carry out related work. To control desertification from various angles, many scientific research institutions have carried out work with their own emphasis on the restoration of grassland topsoil in mountainous desert steppe degraded land. For the essential hardware equipment in this work, that is, the frame structure At present, the current main net frame structures are basicall...
