A self-weight anchored geogrid structure

technical field

The invention relates to the field of geogrid structures, in particular to a self-weight anchored geogrid structure.

Background technique

Geogrid is a major geosynthetic material, which has unique properties and efficacy compared with other geosynthetics. It is often used as a reinforcing material for reinforced soil structures or a reinforcing material for composite materials. Geogrids are divided into four categories: plastic geogrids, steel-plastic geogrids, fiberglass 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 macromolecular polymers by thermoplastic or molding. When used in civil engineering, it is called a geotechnical grid. grille.

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 roots of tree trunks. In some areas, due to the influence of climate and environment, alternating floods and droughts often occur. What happened is that the ordinary geogrid structure is relatively simple and can only be used for simple soil consolidation. When a flood occurs, due to the weak grip with the ground soil, it is likely to be directly lifted, and even lead to trees. Collapse, in dry weather, if water cannot be supplied in time, it will also cause the newly transplanted trees to lack water and not be able to survive.

Beneficial effects of the present invention:

(1) According to the self-weight anchored geogrid structure of the present invention, by installing a connection structure between two grid bodies used to fix the soil at the root of a tree trunk, it is possible to realize the connection between the two grid bodies. It can be quickly installed and fixed, and it can also prevent the two grid bodies from slipping off during use, and ensure the tightness between the two grid bodies, that is, when the two grid bodies need to be sleeved on the trunk. At the root position, just align the insert block on one grill body with the slot position on the other grill body, and then push the two grill bodies gently and forcefully. The position block is slidably connected to the insert block through the fourth spring. When the insert block is inserted into the slot, the limit block that is slidably connected to the slider is pushed into the inside of the slider. When the insert block is completely inserted into the slot, , the limit block will be ejected under the elastic force of the third spring, so that the two grille bodies can be locked and fixed to achieve the effect of quickly fixing the two grille bodies and fixing them firmly. When the grid body is disassembled, it is only necessary to pull the tie rod to make the slider contact the top block, and the top block contacts the limit block, so that the limit block is inserted into the insert block again. At this time, the insert block can be pulled out from the inside of the slot without limit. Thus, the quick disassembly of the two grille bodies is completed.

(2) The self-weight anchored geogrid structure of the present invention can automatically supply water to the roots of tree trunks in dry weather by setting watering structures on both grid bodies, so as to ensure the trunk That is to say, because the water tank with a "concave" structure on the outside and a hollow inside is fixed at the opposite ends of the two grill bodies, water can be stored, and the sponge fixed on the grill body is connected to the water tank through the absorbent cotton strip The internal connection of the protective cover, that is, through the cooperation of the water-absorbing cotton sliver and the sponge, the water inside the water tank can be supplied to the roots of the tree trunk. Since the water-swelling glue is arranged inside the protective cover, through the characteristics of the water-swelling glue, it can be After absorbing water, it expands rapidly, and it can push the slide plate to drive the piston to push the partition board. At this time, the partition board will compress the absorbent tampon. At this time, the absorbent tampon will not supply the water inside the water tank to the sponge. In the weather, the water-swelling glue will automatically shrink, so that the partition board will not squeeze the water-absorbing tampon. At this time, the water-absorbing tampon will automatically supply water to the roots of the trunk, so as to avoid the shortage of water in the trunk in dry weather, greatly guaranteeing the survival rate of tree trunks.

(3) In the self-weight anchored geogrid structure of the present invention, by setting the locking structure inside the two grid bodies, the two grid bodies can be more fixed to the soil along with the growth of the trunk. It is firm, that is, it can further avoid the situation of water and soil loss, and it can also make the grip between the roots of the trunk and the soil stronger. When the diameter becomes larger, the contact plate will be pushed to squeeze the pressure plate through the fixed rod, and the pressure plate will squeeze the gas inside the gas storage tank into the inside of the air channel through the rubber plate. The locking rod of the structure, that is, through the growth of the trunk, the locking rod can be continuously inserted into the interior of the soil, which can not only make the grid body and the ground more stable, but also increase the fixity of the grid body and the ground soil. to avoid soil erosion.

(4) In the self-weight anchored geogrid structure of the present invention, by installing the anchoring structures inside the two grid bodies, the grid bodies can be firmly fixed to the ground soil, thereby preventing soil erosion. It causes the grid body to slip off, and while the anchoring structure is working, it can also drive the soil-fixing structure to work synchronously. It increases the contact area of the ground soil, and can effectively prevent soil erosion and achieve the purpose of protecting the soil. That is, when the grid body is fixed, the fixed pipe is first knocked into the interior of the soil, and when the fixed pipe is completely knocked into the interior of the ground Then, the screw can be rotated. Since the plunger is slidably connected inside the fixed pipe, and the plunger is threadedly connected with the screw, when the screw is rotated, the plunger can be continuously drilled into the soil, so that the plunger can be continuously drilled into the soil. The fixed pipe is suitable for different soil layers, and through the lengthening effect of the fixed pipe, the fixed effect of the fixed pipe on the grid body can be better, and when the insertion rod moves into the soil, the pressing block outside the screw is threadedly connected It will also move with the insertion rod. When the pressing block moves to collide with the soil-fixing rod, the soil-fixing rod will slide to the outside of the fixed pipe under the pressing action of the pressing block through the interference principle of the wedge-shaped block, and it can be inserted. The soil layer outside the fixed pipe can increase the fixed effect of the fixed pipe, and because the fixed pipe increases the cross-sectional area with the soil, it can also play the role of fixing the soil and preventing soil loss.
