Description

Technical Field

[0001] This utility model relates to the field of building engineering, specifically to an ecological gravity retaining wall. Background Technology

[0002] Gravity retaining walls are retaining walls that resist earth pressure by their own weight. They are made of materials such as rubble, flagstone, and concrete. Their advantages include the availability of locally sourced materials, ease of construction, and good economic returns. Gravity retaining walls are widely used in railway, highway, water conservancy, port, and mining projects in my country.

[0003] Gravity retaining walls typically have smooth sides. However, with social development and the increasing demands of the ecological environment, the drawback of these bare sides, which prevent the growth of vegetation, has become increasingly prominent, thus affecting the aesthetics and ecological integrity of gravity retaining walls. Utility Model Content

[0004] The purpose of this invention is to overcome the problems of insufficient aesthetics and ecological performance of existing gravity retaining walls, and to provide an ecological gravity retaining wall that can effectively improve the problem of bare and unsightly sides of existing retaining walls.

[0005] To achieve the above objectives, this utility model provides an ecological gravity retaining wall. The gravity retaining wall includes a main body with vertical sides. Multiple planting buckets filled with planting soil are embedded within the main body. A portion of each planting bucket extends beyond the vertical side of the main body to form a planting end, which is used for planting vegetation. The planting end is connected to a drip irrigation system, and the planting bucket is connected to a drainage system. This technical solution, with its vertically shaped retaining wall, is particularly suitable for use in riverside sections. Its vertical surface faces the river, thus not affecting the river's flow area. By pre-embedding planting buckets inside the retaining wall and allowing a portion to extend beyond it, plants can be planted on the extended end, effectively increasing the aesthetic appeal of the retaining wall. Of course, the retaining wall provided in this application is not only suitable for riverside sections but also for high slopes, mines, parking lots, and other locations.

[0006] The planting buckets inside the retaining wall provided in this application are irrigated by a drip irrigation system, which avoids the plant death that may occur due to insufficient irrigation when relying solely on natural rainwater. Excess water can be drained through the drainage system during the rainy season to prevent the plants from being waterlogged. This greatly improves the survival rate and lifespan of the plants. The retaining wall provided in this application is ecological, environmentally friendly, and aesthetically pleasing.

[0007] This invention does not have any special requirements for the type of plant to be planted; any commonly used plant can be used, such as drought-resistant plants, waterlogging-resistant plants, or other types of plants.

[0008] Preferably, the planting bucket is tilted, with the planting end higher than the other end, and the tilt angle of the planting bucket is 2-5%. The tilt angle refers to the drop height per 100 meters, and a tilt angle of 2-5% means a drop of 2-5 meters per 100 meters. By making the planting bucket slightly tilted, excess drip irrigation solution can be easily drained.

[0009] Preferably, the drip irrigation system includes a main drip irrigation pipe, and each of the planting ends is connected to the main drip irrigation pipe via drip irrigation branch pipes, so that the drip irrigation solution in the main drip irrigation pipe can flow to the planting end. With this structure, directional drip irrigation can be achieved for each planting bucket through the drip irrigation branch pipes, and the main drip irrigation pipe can be connected to a water source or similar source via a pump.

[0010] Preferably, the drainage system includes a main drainage pipe installed within the retaining wall body, and the planting bucket is connected to the main drainage pipe via a branch drainage pipe, with one end of the main drainage pipe connected to the outside. With this structure, excess drip irrigation solution or accumulated rainwater in the planting bucket can be drained through the drainage system.

[0011] Preferably, the drainage branch pipe is vertically arranged, with one end inserted into the planting bucket and the other end inserted into the main drainage pipe. The length of the drainage branch pipe inserted into the planting bucket is 50-100mm, and the length of the drainage branch pipe inserted into the main drainage pipe is 15-25mm. Inserting a portion of the drainage branch pipe into the planting bucket allows only a certain height of accumulated water to overflow into the drainage branch pipe, ensuring that some water always remains at the bottom of the planting bucket to provide the necessary moisture to the planted plants. Inserting a portion of the drainage branch pipe into the main drainage pipe allows water to flow smoothly into the main drainage pipe, preventing potential leakage at the connection point.

[0012] Preferably, the portion of the drainage branch pipe inserted into the planting bucket is wrapped with non-woven fabric. The non-woven fabric allows water to pass through while trapping soil, thereby preventing potential soil loss during drainage.

[0013] Preferably, the upper end of the planting end is open and its end face is inclined to increase the exposed surface area of ​​the planting soil inside the planting end. With this structure, the upper part of the planting end can be cut off to make its upper end face inclined, increasing the exposed surface area of ​​the planting soil inside the planting end, which is beneficial for collecting natural rainwater during rainfall and promoting plant root growth.

[0014] Preferably, the main drain pipe is inclined, with its lower end connected to the outside. An inclined drain pipe facilitates smoother drainage.

[0015] Preferably, the main body of the retaining wall is set in the riverside section, with its vertical side facing the river, and a guardrail is installed at the top of the main body of the retaining wall. Multiple rows of planting barrels are buried inside the main body of the retaining wall from bottom to top. The normal water level of the river is between h1 and h2. The planting barrels below the minimum normal water level of the river are set to plant aquatic plants, the planting barrels above the maximum water level of the river are set to plant drought-resistant climbing plants, and the planting barrels between the normal water level of the river h1 and h2 are set to plant flood-resistant plants.

[0016] The retaining wall structure proposed in this application is installed on the slope of the riverside section. Different types of plants can be planted at different heights according to the normal water level of the river to adapt to changes in the river level. Drought-resistant climbing plants at higher elevations can climb with the help of the railing to improve aesthetics, while flood-resistant plants at lower elevations can provide habitats for aquatic organisms, which is conducive to improving the production environment.

[0017] Preferably, the other side of the retaining wall body is inclined, so that the cross-section of the retaining wall body gradually increases from top to bottom, and backfill soil is compacted on the other side of the retaining wall body. With this structure, the other side of the retaining wall body is set to be inclined, and a certain amount of gravity is provided on it by the backfill soil, thereby improving the stability of the retaining wall body.

[0018] Gravity retaining walls are widely used in production and daily life. The retaining wall provided in this application can improve the problems of traditional retaining walls being unsightly, rigid, and lacking aesthetic appeal. Furthermore, when installed on riverside slopes, different plants can be planted at different heights according to changes in river water levels, making full use of the river's abundant water resources. The planted flood-tolerant plants can provide habitats for aquatic organisms, which is beneficial to improving the ecological environment. Attached Figure Description

[0026] In some embodiments, such as Figure 1 and 2 As shown, an ecological gravity retaining wall is provided, wherein the gravity retaining wall includes a concrete retaining wall body 1, the side of the retaining wall body 1 is vertical, a plurality of planting buckets 2 are embedded in the retaining wall body 1, the planting buckets 2 are filled with planting soil, a part of the planting bucket 2 extends out of the vertical side of the retaining wall body to form a planting end 2a, the planting end 2a is used to plant green plants, the planting end 2a is connected to a drip irrigation system, and the planting bucket 2 is connected to a drainage system.

[0027] In some embodiments, the other side of the retaining wall body 1 is inclined, so that the cross-section of the retaining wall body 1 gradually increases from top to bottom. The retaining wall body 1 can be set at the slope 5, with its inclined side facing the slope 5, and the vertical side of the retaining wall body 1 facing the river or road surface. Backfill soil 4 is filled between the other side of the retaining wall body 1 (i.e., the inclined side) and the slope 5. The backfill soil 4 is compacted on the other side of the retaining wall body 1 to provide it with a certain weight. To facilitate the drainage of rainwater in the backfill soil 4, multiple rows of drainage blind ditches 3 are provided from bottom to top on the other side of the retaining wall body 1. The drainage blind ditches 3 have holes to allow water in the backfill soil to enter the drainage blind ditches 3. The drainage blind ditches 3 are connected to the main drainage pipe 8.

[0028] In some embodiments, the planting bucket 2 is tilted, with its planting end 2a higher than the other end. The tilt slope of the planting bucket 2 is 2-5%. Depending on the position of the planting bucket 2 within the retaining wall body 1, the length of the planting bucket 2 does not exceed 2 / 3 of the thickness of the retaining wall body 1 at its location. The planting bucket 2 can be made of UPVC or iron. Its main body can be a cylindrical structure with open ends. The end inside the retaining wall body 1 is sealed with a matching cap to prevent water from overflowing and eroding the wall material. The planting end 2a is also sealed with a matching cap. The caps at both ends of the planting bucket 2 can be fixed in various ways, such as by using PVC glue. Generally, the length of the planting end 2a can be 200-300mm. The upper part of the planting end 2a is cut (e.g., at a 45° angle) so that the upper end of the planting end 2a is open and its end face is inclined to increase the exposed surface area of ​​the planting soil inside the planting end 2a, so as to receive drip irrigation water and nutrients. It also helps to retain natural rainwater during rainfall, which is beneficial to plant root growth.

[0029] Multiple rows of planting buckets 2 can be installed from bottom to top inside the main body 1 of the retaining wall. The distance between adjacent planting buckets 2 in the horizontal direction can be about 2m, and the distance between adjacent planting buckets 2 in the vertical direction can be about 1.5m.

[0030] The drip irrigation system includes a main drip irrigation pipe 6, and each planting end 2a is connected to the main drip irrigation pipe 6 via a drip irrigation branch pipe 7, so that the drip irrigation liquid in the main drip irrigation pipe 6 can flow to the planting end 2a. To improve aesthetics, the main drip irrigation pipe 6 and the drip irrigation branch pipe 7 can be buried inside the retaining wall body 1. Alternatively, for ease of maintenance, the main drip irrigation pipe 6 and the drip irrigation branch pipe 7 can be fixed to the vertical surface of the retaining wall body 1 and hidden by the planted plants to improve its aesthetics.
