Abstract
Description
Technical Field
[0001] This utility model relates to the field of retaining block technology, and more specifically, to a modular retaining block for soil and water conservation on slopes. Background Technology
[0002] Soil erosion has always been a serious problem in sloping environments. It not only leads to a decline in soil fertility and damage to land resources, but may also trigger geological disasters such as landslides, posing a serious threat to the surrounding ecological environment and the safety of people's lives and property.
[0003] Existing modular retaining blocks often employ simple stacking methods, with construction workers merely piling the blocks together like building blocks, using a single anchor for reinforcement. However, this only strengthens the connection between the blocks and the slope to a certain extent. This method is relatively simple and limited. When facing shear forces from the slope, these modular blocks struggle to form a cohesive whole to resist the forces, resulting in severely insufficient overall shear resistance. Once the slope experiences significant stress changes, such as increased soil pressure due to heavy rain or minor geological activity, these blocks, lacking mechanical interlocking, are prone to relative sliding and misalignment, thus affecting the stability of the entire slope protection structure. Therefore, we propose a modular retaining block design for slope soil and water conservation. Utility Model Content
[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology, adapt to the needs of reality, and provide a modular retaining block for soil and water conservation on slopes, so as to solve the technical problems of poor overall integrity and insufficient synergistic shear resistance of the existing modular retaining blocks.
[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a modular retaining block for slope soil and water conservation, comprising a block body, wherein at least two channels are provided inside the block body, namely a first channel and a second channel, a fixing mechanism is provided inside the first channel and the second channel, and an auxiliary mechanism is provided inside the fixing mechanism, the fixing mechanism including a guide opening and a conical hopper, the guide opening having a tapered shape that is larger at the top and smaller at the bottom, the conical hopper being fixedly installed at the bottom of the block body, and toothed blocks being fixedly installed on the periphery of the conical hopper, the inner peripheral wall of the guide opening being provided with a limiting tooth groove, the toothed blocks being able to engage with the limiting tooth groove, the auxiliary mechanism including an elastic sheet, the elastic sheet being disposed inside the channel, and the outer peripheral wall of the elastic sheet being provided with barbs.
[0006] Preferably, the fixing mechanism further includes a first guide groove, which is disposed at the inclined surface of the guide opening. The inner walls of the first channel and the second channel are both provided with second guide grooves, and the first guide groove and the second guide groove are in communication.
[0007] Preferably, the auxiliary mechanism further includes a fixed sleeve, which is disposed inside the channel. The elastic sheet extends axially along the inner wall of the fixed sleeve. A rod is fixedly installed at the bottom of the fixed sleeve. A limit slot is provided at the guide port corresponding to the position of the rod. The rod is inserted into the limit slot.
[0008] Preferably, the bottom of the conical bucket has a pointed conical structure.
[0009] Preferably, the outer diameter of the fixing sleeve is smaller than the inner diameter of the channel.
[0010] Preferably, the elastic sheets are arranged in a circumferential array on the inner circumferential wall of the fixed sleeve.
[0011] Preferably, the front side of the block body is provided with planting holes, and fixing teeth are fixedly installed on both sides of the block body.
[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. This utility model features a conical hopper at the bottom of the masonry block with a matching guide opening at its top. The tapered design of the guide opening provides automatic guidance and error tolerance, allowing the upper and lower layers of blocks to automatically align during stacking and forming a mechanical interlock through the meshing of toothed blocks and limiting grooves. This changes the loose state of traditional simply stacked masonry blocks, making all blocks interlock into an organic whole, capable of collectively and effectively resisting the shear force transmitted from the slope, greatly enhancing the integrity and stability of the retaining wall, and solving the problems of poor overall integrity and insufficient collaborative shear resistance of existing modular retaining blocks.
[0013] 2. This utility model also forms a second, powerful anti-pull-out defense line through the radial clamping force generated by the deformation of the elastic sheet and the reverse mechanical locking effect generated by the barbs on its surface. This dual protection mechanism of mechanical interlocking and friction locking enables the structure to maintain extremely high stability when facing stress changes caused by heavy rain, earthquakes, etc., effectively preventing block misalignment and slippage. Furthermore, by utilizing the first and second diversion channels, water accumulated behind the wall can be quickly and orderly discharged, significantly reducing the risk of instability caused by the accumulation of hydrostatic pressure, and enhancing the durability and reliability of the structure under severe weather conditions.

[0016] Example: Figures 1 to 7 As shown, this utility model relates to a modular retaining block for slope soil and water conservation, comprising a block body 1, with at least two channels inside the block body 1, namely a first channel 11 and a second channel 12. A planting hole 5 is provided on the front of the block body 1, and fixing teeth 13 are fixedly installed on both sides of the block body 1. A fixing mechanism 2 is provided inside the first channel 11 and the second channel 12, and an auxiliary mechanism 3 is provided inside the fixing mechanism 2. The fixing mechanism 2 includes a guide opening 21 and a conical hopper 24. The guide opening 21 has a tapered shape, wider at the top and narrower at the bottom. The conical hopper 24 is fixedly installed at the bottom of the block body 1, and the bottom of the conical hopper 24 is... The conical structure has toothed blocks 241 fixedly installed around its periphery. The inner wall of the guide opening 21 is provided with limiting grooves 22, allowing the toothed blocks 241 to engage with the limiting grooves 22. The auxiliary mechanism 3 includes an elastic plate 32, located inside the channel, with barbs 33 on its outer wall. This invention, by setting a conical hopper 24 at the bottom of the block and opening a matching guide opening 21 at its top, features a tapered design with automatic guidance and fault tolerance. This allows the upper and lower layers of blocks to automatically align during stacking and forms a mechanical interlock through the engagement of the toothed blocks 241 and the limiting grooves 22. This changes the loose state of traditional simple block stacking, making all blocks interlock into an organic whole, effectively resisting the shear force transmitted from the slope, greatly enhancing the integrity and stability of the retaining wall, and solving the problems of poor overall integrity and insufficient collaborative shear resistance of existing modular retaining blocks.
[0017] Furthermore, such as Figures 2 to 4 As shown, the fixing mechanism 2 also includes a first guide channel 23, which is located at the inclined surface of the guide port 21. The inner walls of the first channel 11 and the second channel 12 are both provided with second guide channels 231. The first guide channel 23 and the second guide channel 231 are connected. By using the first guide channel 23 and the second guide channel 231, the water accumulated behind the wall can be quickly and orderly discharged, which significantly reduces the risk of instability caused by the accumulation of hydrostatic pressure and enhances the durability and reliability of the structure under severe weather conditions.
[0018] Furthermore, such as Figures 5 to 6 As shown, the auxiliary mechanism 3 also includes a fixed sleeve 31, which is installed inside the channel. The outer diameter of the fixed sleeve 31 is smaller than the inner diameter of the channel. Elastic plates 32 extend axially along the inner wall of the fixed sleeve 31. The elastic plates 32 are arranged in a circular array on the inner circumferential wall of the fixed sleeve 31. A plug rod 311 is fixedly installed at the bottom of the fixed sleeve 31. A limit slot 211 is opened at the corresponding position of the guide port 21 and the limit slot 211. The plug rod 311 is inserted into the limit slot 211. The radial clamping force generated by the deformation of the elastic plate 32 and the reverse mechanical locking effect generated by the barbs 33 on its surface form a second strong anti-pull-out defense line. This dual guarantee mechanism of mechanical interlocking and friction locking enables the structure to maintain extremely high stability when facing stress changes caused by rainstorms, earthquakes, etc., and effectively prevents the block misalignment and slippage.
[0019] Working principle: This embodiment provides a modular retaining block for soil and water conservation on slopes. When in use, after leveling the ground, the block body 1 is placed on the ground. At this time, the conical hopper 24 at the bottom of the bottom block body 1 can be inserted into the soil, and the toothed blocks 241 fixedly installed around the conical hopper 24 are used to fix the bottom block body 1.
[0020] Align the conical hopper 24 at the bottom of the upper block body 1 with the guide opening 21 at the top of the second channel 12 opened in the lower block body 1. At this time, the block body 1 can be tilted and stacked. Because the guide opening 21 has a reduced shape that is larger at the top and smaller at the bottom, it allows for a large positional tolerance and can automatically guide the conical hopper 24 to slide towards the center, achieving rapid alignment. Under the action of gravity, the upper block body 1 sinks, and the toothed block 241 fixedly installed on the outside of its bottom conical hopper 24 corresponds to the limiting tooth groove 22 of the guide opening 21 at the top of the second channel 12 opened in the lower block body 1, thus completing the engagement.
[0021] At this point, after several layers of masonry are laid, the fixing sleeve 31 is inserted and passes through the first channel 11 of the upper layer and into the second channel 12 of the lower layer, completing the first fixing of the upper and lower masonry blocks 1. Then, the anchor rod 4 is inserted from inside the fixing sleeve 31. When the anchor rod 4 enters the fixing sleeve 31, it squeezes the elastic sheet 32, and its elastic body is strongly compressed. At this time, the barbs 33 set on the inner wall of the elastic sheet 32 rebound and embed into the micro-unevenness of the anchor rod 4 in the opposite direction, preventing it from being pulled out.
[0022] When rainfall enters the area of the block body 1, most of the water flow will be guided by the first guide channel 23 set at the inclined surface of the guide port 21 to the second guide channel 231 on the inner wall of the first channel 11 and the second channel 12. It will be quickly reversed to the bottom and discharged. Soil will be filled in the planting hole 5 and native plants will be planted. The plant roots will penetrate downward into the slope and connect laterally through the ecological connection holes to form a strong biological root network. Working in conjunction with the mechanical anchoring network of the block, the soil will be physically and permanently fixed, achieving true ecological sustainability of soil and water conservation.
[0023] The embodiments disclosed herein are preferred embodiments, but are not limited thereto. Those skilled in the art can readily grasp the spirit of this utility model based on the above embodiments and make different extensions and variations. However, as long as they do not depart from the spirit of this utility model, they are all within the protection scope of this utility model.
