Self-weight anchorage type geogrid structure

Abstract

The invention relates to the field of geogrid structures, in particular to a self-weight anchorage type geogrid structure. The self-weight anchorage type geogrid structure comprises a fixed sleeve, watering structures, locking structures, connecting structures, anchoring structures and soil fixing structures, the watering structures are arranged on two geogrid bodies, in the drought weather, watercan be automatically supplied to tree trunk roots, trunk growth can be ensured, through the locking structure, road holding of the tree trunk roots and soil is higher, the anchoring structures are arranged in the two geogrid bodies, the geogrid bodies are firmly fixed to the ground soil, the condition of geogrid body slippage caused by water and soil losses can be prevented, when the anchoring structures work, the soil fixing structures can be synchronously driven to work, through work of the soil fixing structures, the geogrid bodies and the ground soil can be more strongly fixed, due to increasing of the contact area with the ground soil, the water and soil losses can be effectively prevented, and the aim of protecting soil is achieved.

Description

technical field [0001] The invention relates to the field of geogrid structures, in particular to a self-weight-anchored geogrid structure. Background technique [0002] Geogrid (geogrid) is a main geosynthetic material, compared with other geosynthetics, it has unique performance and efficacy. It is often used as reinforcement for reinforced soil structures or reinforcement for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, glass fiber geogrids and polyester warp-knitted polyester geogrids. The grid is a two-dimensional grid or a three-dimensional grid screen with a certain height made of polypropylene, polyvinyl chloride and other polymers through thermoplastic or molded. When used as a civil engineering, it is called geotechnical grille.

Problems solved by technology

[0003] At present, in order to ensure the survival rate of newly transplanted trees, that is, to ensure the stability of trees and soil, geogrids are also installed at the root of the trunk. Due to the influence of climate and environment, alternating floods and droughts often occur in some areas. What happened is that the ordinary geogrid has a relatively simple structure and can only be used for simple soil stabilization. When a flood breaks out, due to the weak grip with the ground soil, it is likely to be lifted directly, and even cause trees Collapse, in dry weather, if the water cannot be supplied in time, it will also cause the newly transplanted trees to be short of water and unable to survive
