Description

Technical Field

[0001] The utility model relates to the field of slope protection, in particular to an ecological reinforced earth gabion retaining wall with directional drainage. Background Art

[0002] Gabion retaining walls are made of gabion boxes with a side length of 0.5m to 1m. They are often used for river and highway slope protection. They have the advantages of simple construction, good durability and long service life. The units that make up the gabion retaining wall are hexagonal meshes woven from galvanized steel wires. They are generally produced in advance by the factory and transported to the construction site. In actual construction, by filling the gabion boxes with stones, the gabion boxes are connected together horizontally to form retaining wall units, and then stacked in sequence to form a retaining wall. At present, the filling stones of the gabion retaining wall are usually directly thrown into the mesh cages, and the filling stones collide with the mesh cages, which poses a risk of damaging the mesh cages.

[0003] In addition, although there are large gaps in the gabion retaining wall, which is conducive to the discharge of water behind the retaining wall, it will also bring out impurities such as mud and sand and attach to the surface of the gabion retaining wall. On the one hand, the surface of the gabion is uneven and not easy to clean, which has a great impact on the appearance of the gabion retaining wall. On the other hand, the impurities brought out by rainwater contain more sand and stone, and the surface coating will be gradually destroyed by frequent scouring of the gabion mesh. Over time, under the action of dynamic loads such as upper vehicles, the retaining wall may undergo local deformation, which can easily lead to the overall collapse of the gabion retaining wall. Utility Model Content

[0004] The purpose of the utility model is to provide an ecological reinforced earth gabion retaining wall with directional water drainage. The gabion boxes, the reinforced belts arranged in the backfill soil and the planting boxes ensure the ecology of the gabion retaining wall. In addition, the anti-seepage parts of the utility model can not only realize directional water drainage but also protect the integrity of the boxes during construction. At the same time, the directional water drainage performance is environmentally friendly.

[0005] The technical solution to achieve the purpose of this utility model is as follows:

[0006] The utility model provides a directional water-repellent ecological reinforced soil gabion retaining wall, comprising: a gabion box, a reinforcement belt, and a planting box. The gabion box is arranged on the slope surface, the gabion box is distributed in a step-like manner in the vertical direction, the gabion box is extended in the longitudinal direction to form a retaining wall, the back of the retaining wall is backfill soil, and the reinforcement belt is arranged in the backfill soil;

[0007] The planting net box is arranged outside the gabion net box, the planting net box is fixedly connected to the gabion net box, and green plants are planted in the planting net box;

[0008] The bottom of the gabion box is provided with an anti-seepage member for directional water drainage, and the water in the gabion box flows into the planting box.

[0009] In an embodiment of the present utility model, the gabion box is made of galvanized steel wire. The gabion box is a box with an open top for filling with stones. The mesh of the gabion box is hexagonal, and the two sides of the mesh are hinged and woven into a box. Adjacent gabion boxes are hinged by steel wires.

[0010] In an embodiment of the present utility model, the anti-seepage member is a polyethylene roadbed board installed at the bottom of the gabion box.

[0023] The present utility model will be described in detail below in conjunction with the embodiments shown in the drawings. It should be noted, however, that these embodiments are not intended to limit the present utility model, and any equivalent transformation or substitution in terms of function, method, or structure made by those of ordinary skill in the art based on these embodiments shall fall within the protection scope of the present utility model.

[0024] Please refer to Figure 1 and Figure 2 , the embodiment of the present utility model provides an ecological reinforced earth gabion retaining wall with directional hydrophobicity, including: a gabion box 1, a reinforced belt, and a planting box 2. The gabion box 1 is arranged at the slope surface, and the gabion boxes 1 are distributed in a stepped shape vertically and extend longitudinally to form a retaining wall. The back of the retaining wall is backfill soil 5. The reinforced belt is arranged in the backfill soil 5. The reinforced belt in the embodiment of the present utility model is preferably a steel-plastic reinforced belt 4, and the reinforced belt is horizontally arranged along the slope direction, and the arrangement spacing of each layer of the reinforced belt is 20 - 30 cm. The planting box 2 is arranged outside the gabion box 1, and the planting box 2 is fixedly connected to the gabion box 1, and green plants 3 are planted in the planting box 2; a water seepage prevention member for directional hydrophobicity is arranged at the bottom of the gabion box 1, and the water flow in the gabion box 1 flows into the planting box 2. Preferably, the water seepage prevention member is a polyethylene subgrade plate 102 installed at the bottom of the gabion box 1. In order to better achieve hydrophobicity, a longitudinally extending drain pipe 201 is arranged at the bottom of the planting box 2 in the embodiment of the present utility model, and part of the water flow in the gabion box 1 enters the planting box 2 and is discharged from the drain pipe 201. Preferably, a geotextile filter 202 is laid on the side wall of the planting box 2. The embodiment of the present utility model also arranges green plants 3 at the top of the backfill soil 5 and the top of the planting box 2, and several green plants 3 form a slope protection planting belt.

[0025] At the inner bottom of the gabion box 1 in the embodiment of the utility model, a polyethylene roadbed board 102 is installed. The steel-plastic reinforced belt 4 is installed at the bottom of each layer of gabion box 1, and one end of the steel-plastic reinforced belt 4 is connected to the upper and lower gabion boxes 1. The planting box 2 is connected to the bottom of each layer of gabion box 1 by steel wires and extends longitudinally along the gabion box 1. Green plants 3 are planted on the upper part of the planting box 2. A geotextile filter cloth 202 is arranged on the side surface of the planting box 2 to ensure the seepage of excess water in the planting box while retaining the soil. Please refer to Figure 3 , in the embodiment of the utility model, the water in the soil behind the wall moves towards the gabion box 1 under the action of soil pressure and its own gravity. The water body in the gabion box 1 converges at the position at the lower part of the retaining wall. Since there is a water seepage prevention member (the water seepage prevention member is preferably a polyethylene roadbed board 102) at the bottom of each layer of gabion box 1, the water seeping out from the soil can only seep out from the outside of the water seepage prevention member. The drain pipe 201 at the bottom of the planting box 2 can effectively accelerate the discharge of rainwater in extreme weather such as heavy rain.

[0026] To prevent the gabion box 1 from being damaged, the gabion box 1 in the embodiment of the utility model is made of galvanized steel wire. The gabion box 1 is a box body with an open top for filling stones. The mesh of the gabion box 1 is hexagonal, and the two sides of the mesh are hinged and woven into a box. Adjacent gabion boxes 1 are hinged by steel wires.

[0027] In the embodiment of the utility model, by arranging a water seepage prevention member at the bottom of the gabion box 1, the water seepage prevention member is preferably a polyethylene roadbed board 102. The polyethylene roadbed board 102 prevents the backfill stones in the gabion box 1 from directly hitting its bottom, which can effectively prevent the gabion wires in the gabion box 1 from being damaged or broken. Moreover, since the water body in the gabion box 1 does not directly seep into the lower gabion box 1, but flows along the bottom of the gabion box 1 into the outer planting box 2, the soil in the planting box 2 is kept moist, and the excess part flows away along the drain pipe 201 at the bottom of the planting box 2. At the same time, the filter geotextile in the planting box 2 is beneficial to the normal seepage of the planting box 2 while preventing soil loss. The backfill soil 5 in the embodiment of the utility model uses the steel-plastic reinforced belt 4 arranged in layers as the reinforcement material. Under the combined action of the steel-plastic reinforced belt 4 and the backfill soil 5, the strength of the backfill soil 5 is significantly improved, and the stability of the slope is enhanced by combining with the outer gabion box 1. The planting of green plants 3 in the embodiment of the utility model has a good decorative effect on the appearance of the gabion retaining wall, and has better ecological benefits compared with traditional gravity retaining walls, anchor retaining walls, cantilever retaining walls, etc.

[0028] An embodiment of the utility model provides an ecological reinforced earth gabion retaining wall with directional hydrophobicity, and the construction process is as follows: First, the vegetation and humus on the surface of the foundation 6 are cleaned, and the foundation is leveled and compacted. When necessary, measures such as replacement filling and ramming are taken to meet the bearing capacity requirements of the foundation 6. Then, the reinforcement materials are laid, and a single gabion cage 1 is assembled and placed on the leveled foundation 6. A polyethylene roadbed board 102 is installed at the bottom of the gabion cage 1, and the quality and specifications of the gabion cage 1 are checked to meet the design requirements. After the installation of the gabion cage 1 is completed, a cage support is set up, and the stone backfilling is carried out in three layers. After each layer is filled, a tension wire is set to ensure that the gabion cage 1 does not undergo large deformation. After the backfilling is completed, the stones are leveled and compacted, and then the cage cover plate 101 of the gabion cage 1 is used for capping. A planting cage 2 is installed outside the gabion cage 1. The planting cage 2 is hinged to the gabion cage 1 with steel wires. An anti-filter geotextile and a drain pipe 201 are laid inside the planting cage 2. After a layer of soil is backfilled to the height of the retaining wall, the soil is preliminarily compacted, and a steel-plastic reinforced belt 4 is laid above it. Then, the construction of each layer of the retaining wall is carried out in sequence until the construction reaches the elevation of the wall top.

[0029] Compared with the traditional gabion retaining wall, for the ecological reinforced earth gabion retaining wall of the embodiment of the utility model, since the polyethylene roadbed board 102 is laid at the bottom of each gabion cage 1, on the one hand, it can effectively prevent the galvanized steel wires from being damaged due to the collision of the gabion cage 1 when backfilling stones into the gabion cage 1, and at the same time, it can also limit the moisture in the backfill soil 5 behind from being discharged through the front of the retaining wall. In addition, the deposited soil in the additionally installed planting cage 2 can provide nutrients for the reproduction of organisms, and the green plants 3 planted above can also beautify the gabion retaining wall, which is beneficial to promoting ecological balance and protecting the diversity of the ecosystem.
