Description

Technical Field

[0001] The utility model aims to provide a protective structure for regreening hard slopes of water banks using honeycomb grids, belonging to the technical field of hard slope protection of water banks. Background Art

[0002] The waterside slope is the transition zone between the water ecosystems such as rivers, lakes, irrigation and drainage channels and the onshore ecosystem. The naturally formed growth environment of the slope vegetation provides an activity area for amphibians. The hard waterside slope includes slope protection methods such as concrete pouring and mortar masonry. Because after the original waterside slope is destroyed, it cannot cope with the scouring of runoff after extreme rainfall, especially the erosion of the waterside around the city is more serious; and then the slope gradually adopts concrete pouring of the original slope surface for hardening protection to form a hard slope, which disrupts the original waterside ecological balance and has a great impact on the overall ecological environment and ecological landscape. The restoration of the ecological environment and ecological landscape of the hard slope is extremely difficult, the restoration time is long, the excavation cost is high, and the investment cost is large. In view of the above-mentioned defects, the inventor has designed a protective structure that does not require re-excavation and uses honeycomb grids to regreen the existing hard slopes of the waterside. Summary of the invention

[0003] The purpose of the present invention is to provide a protective structure for regreening hard slopes of water banks using honeycomb grids, thereby overcoming the deficiencies in the prior art.

[0004] The technical principle of the present invention is to quickly regreen the original hardened slope by laying a flexible honeycomb grid on the hard slope, anchoring the honeycomb grid at the shoulder or foot of the slope which is relatively easy to fix, backfilling with planting soil or spraying with plant growth matrix, and finally laying lawn on the slope.

[0005] The technical solution of the present invention is to include a honeycomb grid laid on the surface of a hard slope, and plastic-sealed steel wire ropes for fixing the honeycomb grid, wherein the plastic-sealed steel wire ropes include straight-pull plastic-sealed steel wire ropes and oblique-pull plastic-sealed steel wire ropes;

[0006] A straight-pull plastic-sealed steel wire rope is inserted into the connection holes of every 3 to 5 rows of the honeycomb grid. The two ends of the straight-pull plastic-sealed steel wire rope are fixed to the slope shoulder and slope foot with coarse threaded anchor piles respectively. The remaining cells at both ends and both sides of the honeycomb grid are anchored by threaded anchors.

[0007] A zigzag-shaped oblique-pull plastic-sealed steel wire rope is set every 5 meters from the shoulder to the middle of the hard slope. The oblique-pull plastic-sealed steel wire rope is set along the waterside direction. The connection point of the zigzag line is the pulling point. The oblique-pull plastic-sealed steel wire rope is fixed with coarse threaded anchor piles at the pulling point to strengthen the stability of the honeycomb grid under the auxiliary slope; the upper oblique-pull plastic-sealed steel wire rope is used to pull the coarse threaded anchor pile of the next oblique-pull plastic-sealed steel wire rope to transfer the gravity after backfilling the middle and lower part of the slope to the coarse threaded anchor pile of the shoulder anchor.

[0008] The straight-pull plastic-sealed steel wire rope is bundled with a binding piece at intervals of 3 to 5 grids along the slope shoulder direction or inserted into the traction limit assembly.

[0009] When the length of the hard slope is greater than 10 meters, add an inclined plastic-sealed steel wire rope for every 4 to 8 meters increase in slope length.

[0010] The length of the threaded anchor tail exposed on the slope is the same as the height of the honeycomb mesh cell.

[0011] The honeycomb grid on the slope surface after paving is backfilled with planting soil or sprayed with plant growth substrate.

[0012] The surface of the filled honeycomb grid is covered with lawn.

[0013] The honeycomb grid cells at the slope shoulder are backfilled with planting soil and compacted, and a layer of honeycomb grid of the same specification is laid on top of the cells, fixed with threaded anchors, filled and compacted to form a water retaining ridge, and the position of the original water collection slope is reserved as a spillway.

[0014] The beneficial effects of the present invention are: [1] the diversity of anchoring methods increases the strength of the honeycomb grid protection, provides space for vegetation growth, and is convenient for operators to operate; [2] it effectively solves the problem of the small number of anchoring points on hard slopes, and uses a variety of combinations of anchor piles and plastic-sealed steel wire ropes to position the honeycomb grid; [3] the honeycomb grid is combined with the rapidly growing root system of the corresponding lawn to form a net, thereby increasing the protection capacity of the slope; [4] the honeycomb grid controls the soil in grids, reduces the displacement of the surface filling material of the slope, and stabilizes the slope.

[0017] In order to make the purpose, technical scheme and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are exemplary only and are not intended to limit the scope of the utility model. In addition, in the following description, the description of known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model; in addition, the technical features involved in the different implementation methods of the utility model described below can be combined with each other as long as they do not conflict with each other. The utility model will be described in more detail below with reference to the accompanying drawings. In each of the accompanying drawings, the same elements are represented by similar figure numerals. For clarity, the various parts in the accompanying drawings are not drawn to scale.

[0018] The utility model is realized by the following technical scheme: (1) by paving a flexible honeycomb grid 2 on a hard slope 1, selecting a honeycomb grid 2 with corresponding design indicators according to the historical causes of the hard slope 1, i.e., the cell size, height, weld tensile strength, porosity, etc. of the honeycomb grid 2, and fixing the honeycomb grid 2 by a corresponding anchoring method: i.e., the middle and foot of the slope are anchored by threaded anchors 4, and the shoulder of the slope is anchored by a combination of anchor piles 5 and plastic-sealed steel wire ropes 3, so that the entire structure is evenly stressed after the honeycomb grid 2 is backfilled. (2) Then backfill the cell filler, which includes planting soil or sprayed plant growth matrix 7, and the growth matrix is ​​a mass of planting soil, wood (grass) fiber, water retaining agent, adhesive, organic fertilizer and other components mixed with water, which can provide a rapid growth environment for the lawn. (3) Finally, surface plants are laid on the slope to quickly regreen the original hardened slope. The surface plant measures are selected from lawns that protect soil and slopes. Because they have formed a surface protection structure through long-term growth, they can quickly take root in a short time. The developed root system is intertwined in the air holes of the honeycomb mesh 2 to form a whole net with it, reducing the erosion of the slope by the water and taking into account the shape and beautification.

[0019] The utility model comprises a honeycomb grid 2 laid on the surface of a hard slope 1, and a plastic-sealed steel wire rope 3 for fixing the honeycomb grid 2, wherein the plastic-sealed steel wire rope 3 comprises a straight-pull plastic-sealed steel wire rope 31 and an oblique-pull plastic-sealed steel wire rope 32;

[0020] A straight-pull plastic-sealed steel wire rope 31 is inserted into the connection holes of every 3 to 5 rows of the honeycomb grid. The two ends of the straight-pull plastic-sealed steel wire rope 31 are respectively fixed to the slope shoulder and the slope foot by coarse threaded anchor piles 5. The remaining cells at both ends of the honeycomb grid 2 and on both sides are anchored by threaded anchors 4.

[0021] A zigzag-shaped oblique-pull plastic-sealed steel wire rope 32 is arranged every 5 meters from the shoulder to the middle of the hard slope 1. The oblique-pull plastic-sealed steel wire rope 32 is arranged along the waterside direction. The connection point of the zigzag line is the pulling point. The oblique-pull plastic-sealed steel wire rope 32 is fixed at the pulling point with a coarse threaded anchor pile 5 to strengthen the stability of the honeycomb grid below the auxiliary slope; the upper oblique-pull plastic-sealed steel wire rope 32 is used to pull the coarse threaded anchor pile 5 of the next oblique-pull plastic-sealed steel wire rope 32 to transfer the gravity after backfilling the middle and lower part of the slope to the coarse threaded anchor pile 5 on the shoulder.

[0022] The straight-pull plastic-sealed steel wire rope 31 is bundled with a binding piece every 3 to 5 cells along the slope shoulder direction or is inserted into the traction limiting assembly 6 before the straight-pull plastic-sealed steel wire rope is inserted.

[0023] When the length of the hard slope 1 is greater than 10 meters, an inclined plastic-sealed steel wire rope 32 is added for every 4 to 8 meters increase in the slope length.

[0024] The length of the rear end of the threaded anchor bar 4 exposed on the slope is equal to the height of the cell of the honeycomb grid 2 sheet material.

[0025] The honeycomb grid on the slope surface after paving is backfilled with planting soil or sprayed with plant growth matrix 7.

[0026] The surface of the filled honeycomb grid 2 is paved with lawn.

[0027] The honeycomb grid 2 cells at the slope shoulder are backfilled with planting soil and compacted, and another layer of honeycomb grid 2 of the same specification is laid on the cells, fixed with threaded anchors 4, filled and compacted to form a water retaining ridge 8, and the original water collection slope position is reserved as a spillway.

[0028] During the specific construction, (1) the hard slope 1 is leveled. Any uneven parts of the hard slope 1 need to be leveled; geotextiles are laid at the parts with cracks and water permeability to prevent the loss of sediment in the slope;

[0029] (2) A single group of honeycomb grids 2 is connected grid by grid on the shoulder of the slope with threaded screws. A straight-pull plastic-sealed steel wire rope 31 is passed through the connection hole every 3 to 5 rows. Anchor points are marked on the hard slope according to the standard size of a single grid (length 373 mm, width 283 mm). The anchor points are set on the lower side of the short side above the current cell to anchor the threaded anchor 4. A percussion drill is used to drill holes vertically on the slope surface at the marked anchor points, and the threaded anchor 4 is anchored in. The length of the tail end of the threaded anchor 4 exposed on the slope surface is the same height as the cell of the honeycomb grid 2 sheet; a coarse threaded anchor pile 5 is nailed into the corresponding position of the slope foot and the slope shoulder every 3 to 5 rows to fix the straight-pull plastic-sealed steel wire rope 31, and the cells at the slope foot and the slope shoulder where the coarse threaded anchor pile 5 is not nailed are anchored in the threaded anchor 4;

[0030] (3) The cells of the bottom row of the honeycomb grid 2 are fixed one by one on the threaded anchor 4, and the straight-pull plastic-sealed steel wire rope 31 is tied and fixed on the coarse-threaded anchor pile 5. The straight-pull plastic-sealed steel wire rope 31 is tied with a tying piece every 3 to 5 cells along the slope shoulder direction or is inserted into the traction limit assembly 6 before the straight-pull plastic-sealed steel wire rope 31 is inserted;

[0031] (4) Repeat the operation in step (3) to lay, anchor and tie the honeycomb grid 2 from the bottom of the slope to the rear end of the slope shoulder until the designed hard slope surface 1 is completely laid;

[0032] (5) After all threaded anchors 4 and straight-pull plastic-sealing steel wire ropes 31 are fixed, an oblique-pull plastic-sealing steel wire rope 32 is set on the honeycomb mesh 2 in the middle of the hard slope 1 according to the slope length. The oblique-pull plastic-sealing steel wire rope 32 is set in a broken line along the water bank direction. The connection point of the broken line is the pulling point. The oblique-pull plastic-sealing steel wire rope 32 is fixed at the pulling point using a coarse-threaded anchor pile 5 to strengthen the stability of the honeycomb mesh below the auxiliary slope.

[0033] After the oblique plastic-sealed steel wire rope in the middle is completed, another oblique plastic-sealed steel wire rope 32 is set on the honeycomb mesh 2 at the upper part of the hard slope 1 to pull the coarse thread anchor pile 5 of the middle oblique plastic-sealed steel wire rope 32, and transfer the gravity after backfilling in the middle and lower part of the slope to the coarse thread anchor pile 5 on the slope shoulder. The use of the oblique plastic-sealed steel wire rope 32 not only increases the stability of the original anchoring method, but also transfers the gravity of the middle and lower part of the slope to the slope shoulder, and also increases the degree of fit between the honeycomb mesh 2 and the slope surface to a certain extent, reducing the amount of sediment seeping from the bottom of the honeycomb mesh 2 in the later stage;

[0034] (6) After the honeycomb mesh on the slope is laid, fill the 2 cells with planting soil or spray-fill the plant growth matrix 7. If the overfill is 5-10 cm, use the back of the hook to pat and compact it. Use the impact force of the spraying to evenly fill the mixture into the cells. The fibers in the growth matrix and the permeable holes of the honeycomb mesh are interlaced on the surface of the slope to form a protective net.

[0035] (7) When laying the lawn on the filled slope, first lay the lawn in full or in sections, then trim and replace or shape it locally; after each lawn is laid and spliced, use bamboo sticks or U-shaped nails to promptly insert the lawn into the backfill planting soil or sprayed plant growth matrix 7 to prevent the lawn from shifting during watering and maintenance; after watering and maintenance, pat the lawn to make the roots of the lawn fully contact with the slope to promote the lawn roots to grow downward as soon as possible;

[0036] (8) The honeycomb grid 2 cells on the slope shoulder are backfilled with planting soil and compacted, and 1 to 2 layers of honeycomb grid 2 of the same specification are laid on top of the cells, fixed with threaded anchors 4, and filled and compacted to form a water retaining ridge 8. The original water collection slope is reserved as a spillway to discharge the water collected on the slope shoulder into the ditch as soon as possible to reduce the water seepage of the slope shoulder.

[0037] By using a flexible honeycomb grid 2 to lay flat on the hard slope 1, the grid is filled with planting soil or sprayed with plant growth matrix 7. Two specifications of anchor rods are used for anchoring, and two forms of plastic-sealed steel wire ropes 3 are used for pulling, and slope shoulder water retaining ridges 8 and local water permeability treatment of the slope are constructed. These methods make the hard slope 1 become an ecological green vegetation slope, which not only provides the possibility of exchange for the waterway ecosystem, but also enhances the ornamental value of the slope landscape.

[0038] Obviously, the described embodiments are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
