Description

Technical Field

[0001] This utility model relates to the field of retaining wall structures, and in particular to a stepped retaining wall structure that can collect rainwater. Background Technology

[0002] Earth walls are structures used to prevent soil or rock from sliding, landslides, or collapses. They are commonly used in the construction of roads, railways, buildings, or other infrastructure. Stepped retaining walls are a type of retaining wall that incorporates a stepped structure in its design. This design typically divides the entire retaining wall into several layers, with each layer forming a stepped height difference. The stepped design can effectively distribute lateral pressure and reduce the load on each individual retaining wall segment.

[0003] Currently, some existing retaining walls lack rainwater collection capabilities. There is no effective system for collecting, filtering, and storing rainwater, which prevents the full utilization of precipitation resources, leading to water waste and hindering the sustainable use of rainwater resources.

[0004] Therefore, those skilled in the art have provided a stepped retaining wall structure capable of collecting rainwater to solve the problems mentioned in the background art. Utility Model Content

[0005] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a stepped retaining wall structure that can collect rainwater. Rainwater can be collected to the center of the wall through grooves. After passing through a filter screen and a gravel filter layer, the rainwater enters the storage tank, making it convenient to collect rainwater for irrigation, landscape ponds or other purposes. A threaded rod can drive a movable block forward to insert into the insert, and a rotating plate pops out the insert, which quickly connects the wall, saving the time and reducing the difficulty of wall installation.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A stepped retaining wall structure for collecting rainwater includes a first wall, a second wall connected to the upper end of the first wall, a third wall connected to the upper end of the second wall, and collection structures provided on the first, second, and third walls. Connecting structures are provided between the first and second walls, and between the second and third walls.

[0008] The collection structure includes grooves, which are located at the center of the upper ends of walls 1, 2, and 3. Filter screens are movably connected inside the upper ends of walls 1, 2, and 3. Fixing seats are fixedly connected inside the upper ends of walls 1, 2, and 3, and gravel filter layers are fixedly connected inside the fixing seats. A liquid storage tank is formed inside wall 1, and multiple No. 1 through-channels are formed inside wall 1. No. 2 through-channels are formed at both the front and rear ends of wall 2, and No. 3 through-channels are formed inside wall 3.

[0009] The above technical solution allows rainwater to move towards the center through grooves and filters, and the collected rainwater is filtered. The gravel filter layer further enhances the filtration effect and removes impurities from the rainwater. The storage tank facilitates the storage of the collected rainwater, making it convenient for irrigation, landscape ponds, or other uses, thus saving resources. The No. 1, No. 2, and No. 3 channels ensure that rainwater collected from multiple walls flows into the storage tank.

[0010] Furthermore, the connection structure includes a plug, which is fixed to the lower ends of the second and third walls. Movable blocks are slidably connected to the upper ends of the first and second walls on both sides. A threaded screw is rotatably connected to the rear end of the movable block. Rotating plates are rotatably connected to the inner sides of the movable block. Slots are provided on both sides of the plug.

[0011] The above technical solution enables modular design through insert blocks and movable blocks, facilitating quick and easy connection to the wall and saving the difficulty and time of wall installation. The rotation of the threaded rod facilitates the insertion of the movable block into the wall and allows the unfolded rotating plate to engage with the slot, thereby completing the snap-fit ​​connection between the movable block and the insert block.

[0012] Furthermore, positioning blocks are fixedly connected to the four corners of the lower end of the filter screen, and positioning grooves are opened at the front and rear ends of both sides of the upper end of the No. 1 wall, the No. 2 wall and the No. 3 wall.

[0013] The above technical solution facilitates the quick installation of the filter screen through the positioning block and positioning groove, and makes it convenient to disassemble and clean or replace the clogged filter screen.

[0014] Furthermore, a valve is provided on one side of the front end of the first wall, and the valve is connected in communication with the liquid storage tank;

[0015] The above technical solution allows for timely release of rainwater when it reaches a certain level, preventing water accumulation from putting pressure on and affecting the wall structure.

[0016] Furthermore, slots are provided on both sides of the upper end of the No. 1 wall and the No. 2 wall, and the movable block slides within the slots.

[0017] The above technical solution allows the movable block to slide inside the slot until it is inserted into the insert block.

[0018] Furthermore, both the rear ends of the No. 1 wall and the No. 2 wall are fixedly connected to fixing rings, and the threaded rod is threadedly connected to the inside of the fixing ring.

[0019] The above technical solution allows the threaded screw to rotate inside the fixed ring, which in turn drives the movable block to move into the wall.

[0020] Furthermore, rotating grooves are provided on both sides of the movable block, and the rotating plate rotates inside the rotating grooves;

[0021] The above technical solution facilitates the rotation of the rotating plate within the two sides of the movable block by setting the rotating groove.

[0022] Furthermore, a connecting spring is fixedly connected to the bottom of the rotating groove, and one side of the connecting spring is fixedly connected to the rotating plate;

[0023] The above technical solution allows the connecting spring to facilitate the rotation plate to pop out and lock into the block after the movable block is inserted into the insert.

[0024] This utility model has the following beneficial effects:

[0025] 1. This utility model proposes a stepped retaining wall structure that can collect rainwater. The collection structure facilitates the collection and filtration of rainwater. Under the action of the groove, the rainwater undergoes the first filtration through the filter screen. After the gravel filter layer filters the rainwater again, it enters the liquid storage tank through the channel. Similarly, other walls can also collect rainwater into the liquid storage tank, which can be used for irrigation, landscape ponds or other purposes, thus saving more resources.

[0026] 2. The present invention proposes a stepped retaining wall structure that can collect rainwater. The connection structure facilitates the connection of the wall. After the insert is inserted into the wall, the movable block moves forward. The compressed connecting spring drives the rotating plate to rotate out and lock into the slot to fix the insert. This facilitates the reduction of construction difficulty and saves time. Attached Figure Description

A valve 211 is provided on one side of the front end of the No. 1 wall 1. The valve 211 is connected to the liquid storage tank 210. The valve 211 allows for timely release of rainwater when a certain amount is stored, preventing water accumulation from putting pressure on the wall structure.

[0038] Reference Figure 1 , Figure 4 and Figure 5The connecting structure 3 includes an insert block 301, which is fixed to the lower ends of the second wall 4 and the third wall 5. Movable blocks 304 are slidably connected to the upper interior sides of the first wall 1 and the second wall 4. The insert block 301 and the movable blocks 304 enable a modular design, facilitating quick and easy wall connection and reducing installation difficulty and time. Slots 303 are provided on both upper ends of the first wall 1 and the second wall 4, allowing the movable blocks 304 to slide within the slots 303. The slots 303 facilitate the sliding of the movable blocks 304 until they are inserted into the insert block 301. A threaded rod 307 is rotatably connected to the rear end of the movable block 304. Fixing rings 308 are fixedly connected to the rear ends of the first wall 1 and the second wall 4. The threaded rod 307 is threadedly connected to the fixing rings 308, allowing the threaded rod 307 to rotate within them and drive the rotation of the threaded rod 307. The movable block 304 moves into the wall. Rotating plates 305 are rotatably connected to both sides of the movable block 304. Rotating grooves 309 are provided on both sides of the movable block 304. The rotating plates 305 rotate inside the rotating grooves 309. The rotating grooves 309 facilitate the rotation of the rotating plates 305 inside the movable block 304. A connecting spring 306 is fixedly connected to the bottom of the rotating groove 309. One side of the connecting spring 306 is fixedly connected to the rotating plate 305. The connecting spring 306 facilitates the rotation of the rotating plate 305 after the movable block 304 is inserted into the insert block 301, so that it is locked into the block. The insert block 301 has slots 302 on both sides.

[0039] Working principle: During use, first install wall 1 (number 1). After installation, connect wall 4 (number 2). Insert the insert block 301 into wall 1. Press the rotating plate 305 inward to compress the connecting spring 306. Insert the movable block 304 through the fixing ring 308 into wall 1. Rotate the threaded screw 307 to make it rotate inside the fixing ring 308. The movable block 304 is driven forward by the screw until it is inserted into the insert block 301. The compressed connecting spring 306 causes the rotating plate 305 to pop out, locking it into the slot 302, thus fixing the insert block 301. This quickly connects the two walls. Similarly, connect wall 4 (number 2) and wall 5 (number 3), reducing construction difficulty and saving time. The function of groove 201 is to allow rainwater to automatically flow to the center of the wall during rainfall, where it undergoes initial filtration through filter screen 202 and secondary filtration through gravel filter layer 206. After filtration, the rainwater flows into storage tank 210 through channel 207, thus completing the rainwater collection. Similarly, walls 4 and 5 can send rainwater into storage tank 210 through multiple channels, completing the rainwater collection. After opening valve 211, the rainwater can be used for irrigation, landscape ponds, or other purposes, further saving resources. Storage tank 210 is equipped with a liquid level sensor. When the rainfall is heavy and there is a lot of rainwater in storage tank 210, valve 211 can be opened to let some water out of the tank, preventing excessive rainwater from putting pressure on the wall structure and causing damage.
