Description

Technical Field

[0001] This utility model relates to the field of water conservancy engineering technology, specifically a masonry slope protection structure for water conservancy projects. Background Technology

[0002] There are many villages along the Honggou River. In order to meet the living needs of the riverside residents, waterfront steps are often set up. The current waterfront steps are mostly made of masonry. Waterfront steps are prone to water accumulation due to rainy weather. After a long period of water accumulation, moss is prone to grow. The presence of water or moss makes the steps slippery, posing a risk of residents slipping into the river when going up or down.

[0003] Patent document CN212801413U discloses a masonry slope protection structure in water conservancy engineering, comprising a crushed stone cushion layer, a slope base layer, and a stepped layer arranged sequentially along the thickness direction. The crushed stone cushion layer and the slope base layer have riprap protection at their riverbed ends. The stepped layer comprises a multi-level masonry strip structure, with each level of masonry strip forming a foothold area for stepping down. A groove is formed on the top of the masonry strip corresponding to the foothold area, and a grid plate is provided on the top of the groove. A drainage hole communicating with the outside is formed on the lower outer side of the groove. In this slope protection structure, the foothold area formed by the grid plate on the masonry strip allows accumulated water to pass through the grid plate into the groove and then flow out through the drainage hole. The grid plate is breathable and prevents water accumulation and moss growth, providing a safe foothold for residents going up and down, reducing the probability of accidents.

[0004] Although the existing technology can drain water from the masonry stone by using grooves and outlets, when water accumulates on the surface of the masonry stone, the water cannot flow smoothly into the grooves because the surface of the masonry stone is flat. Therefore, a new masonry stone slope protection structure for water conservancy projects is proposed to optimize the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a masonry slope protection structure for water conservancy projects, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solutions:

[0007] A masonry slope protection structure for water conservancy projects includes a crushed stone cushion layer, a slope base layer, and a stepped layer arranged sequentially along the thickness direction. The bottom ends of the crushed stone cushion layer and the slope base layer are provided with riprap protection. The stepped layer includes multiple levels of masonry blocks. A groove is formed on one side of the top surface of the masonry blocks. The masonry blocks are laid on the slope base layer in an overlapping manner. Planting troughs are formed at the edges of the overlapping parts of the top surfaces of the masonry blocks. One end of the planting trough corresponds to the groove, and the other end of the planting trough is connected to a turning groove. Drainage grooves are uniformly formed on the surface of the masonry blocks. The drainage grooves are connected to the grooves. The turning grooves are connected to the grooves through corresponding drainage grooves. The planting troughs and turning grooves are set in a continuous downward slope. The drainage grooves are set in a downward slope towards the grooves. Drainage holes are uniformly formed at the bottom of the grooves corresponding to the planting troughs.

[0008] As a further embodiment of this utility model: an L-shaped baffle plate is fixedly connected to the side of the masonry stone corresponding to the port of the drainage hole.

[0009] As a further improvement of this utility model: a first placement step is provided at the top of the groove corresponding to the masonry strip, and a first grate is placed in the first placement step.

[0010] As a further improvement of this utility model: countersunk holes are provided at the four corners of the masonry blocks, and insertion holes are provided at the corresponding countersunk holes in the slope base. The uppermost and lowermost insertion holes are deeper and can completely accommodate the limiting pins. The limiting pins are inserted into the insertion holes and the corresponding countersunk holes, and the heads of the limiting pins are sunk into the countersunk holes.

[0011] As a further embodiment of this utility model: a water storage tank is provided at the bottom of the slope base, a water supply pipe is connected to the water storage tank, a water pump is connected to the water supply pipe, the water pump is connected to a power source for switching, and the top of the water supply pipe corresponds to the planting trough on the top masonry stone.

[0012] As a further improvement of this utility model: the top opening of the water storage tank is provided with a second placement step, a second grate is placed inside the second placement step, and an isolation net frame is fixedly connected to one end of the water supply pipe inserted into the water storage tank.

[0013] Compared with the prior art, the beneficial effects of the present invention are:

[0014] 1. In this utility model, the water flows down the slope in the planting trough and the turning trough. The water in the turning trough flows into the groove through the slope of the drainage trough and is collected. When the water is on the masonry stone, it slides into the drainage trough and then flows into the groove through the slope of the drainage trough and is collected. This effectively prevents the water from accumulating on the surface of the masonry stone and causing it to become slippery.

[0015] 2. This utility model uses an L-shaped baffle to block the water draining from the drainage hole, preventing the water from draining too quickly and causing the water column to form a parabola that crosses the planting trough, thus affecting the water replenishment of the planting trough.

[0016] 3. In this utility model, the masonry blocks are stacked together and the limiting pins are inserted into the socket through the countersunk holes to form a limit, thereby improving the stability of the masonry blocks. At the same time, the corresponding limiting pins can be removed to facilitate the removal, replacement and maintenance of individual masonry blocks.

[0017] 4. This utility model uses a water storage tank at the bottom to collect and store water. A water pump and a water pipe are used to transport the stored water upwards. The water flows down the slope in the planting trough and the turning trough. The water in the turning trough flows into the groove through the slope of the drain trough and is collected. The water in the groove is discharged into the planting trough below through the drain hole, thus forming a circulating irrigation effect, which makes it convenient to replenish water to the planting trough.

[0018] 5. This utility model isolates the space above the groove with a first grate, isolates the space above the water storage tank with a second grate, and isolates the water inlet end of the water supply pipe with an isolation mesh frame, thereby effectively reducing large impurities.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4 In this embodiment of the present invention, a masonry slope protection structure for a water conservancy project includes a crushed stone cushion layer 1, a slope base layer 2, and a step layer 3 arranged sequentially along the thickness direction. The bottom end of the crushed stone cushion layer 1 and the slope base layer 2 is provided with a riprap bottom protection 4. The step layer 3 includes multi-level masonry strips 5. A groove 6 is provided on one side of the top surface of the masonry strips 5. The masonry strips 5 are laid on the slope base layer 2 with each other overlapping. Planting troughs 7 are provided at the edges of the overlapping parts of the top surface of the masonry strips 5. One end of the planting trough 7 corresponds to the groove 6, and the other end of the planting trough 7 is connected to a turning groove 8. Drainage grooves 9 are uniformly provided on the surface of the masonry strips 5. The drainage grooves 9 are connected to the groove 6. The turning groove 8 is connected to the groove 6 through the corresponding drainage groove 9. The planting groove 7 and the turning groove 8 are arranged in a continuous downward slope. The drainage groove 9 is arranged in a downward slope towards the groove 6. Drainage holes 10 are uniformly provided at the bottom of the groove 6 corresponding to the planting groove 7.

[0026] The water flows down the slope in the planting trough 7 and the turning trough 8. The water in the turning trough 8 flows into the groove 6 through the slope of the drainage trough 9 and is collected. When the water is on the masonry 5, it slides down into the drainage trough 9 and then flows into the groove 6 through the slope of the drainage trough 9. This effectively prevents the surface of the masonry 5 from becoming slippery due to water accumulation.

[0027] An L-shaped baffle plate 11 is fixedly connected to the side of the masonry 5 corresponding to the port of the drainage hole 10.

[0028] The L-shaped baffle plate 11 blocks the water draining from the drain hole 10, preventing the water from draining too quickly and causing the water column to form a parabola that crosses the planting trough 7, thus affecting the water replenishment of the planting trough 7.

[0029] The four corners of the masonry blocks 5 are provided with countersunk holes 14. The slope base 2 is provided with insertion holes 15 corresponding to the countersunk holes 14. The uppermost insertion hole 15 and the lowermost insertion hole 15 are deep enough to completely accommodate the limiting pin 21. The limiting pin 21 is inserted into both the insertion hole 15 and the corresponding countersunk hole 14. The head of the limiting pin 21 is sunk into the countersunk hole 14.

[0030] The masonry blocks 5 are stacked on top of each other and are constrained by the limiting pins 21 that pass through the countersunk holes 14 and are inserted into the insertion holes 15, thereby improving the stability of the masonry blocks 5. At the same time, the corresponding limiting pins 21 can be removed to facilitate the removal, replacement and maintenance of individual masonry blocks 5.

[0031] A water storage tank 16 is provided at the bottom of the slope base 2. A water supply pipe 17 is connected to the water storage tank 16. A water pump 22 is connected to the water supply pipe 17. The water pump 22 is connected to a power source and can be switched on and off. The top of the water supply pipe 17 corresponds to the planting trough 7 on the top masonry slab 5.

[0032] The water is collected and stored at the bottom by the water storage tank 16. The water is pumped upward by the water pump 22 and the water pipe 17. The water flows down the slope in the planting trough 7 and the turning trough 8. The water in the turning trough 8 flows into the groove 6 through the slope of the drain trough 9 and is collected. The water in the groove 6 is discharged into the planting trough 7 below through the drain hole 10, thus forming a circulating irrigation effect, which makes it convenient to replenish water to the planting trough 7.

[0033] The top of the mortar-grouted stone block 5 corresponding to the groove 6 is provided with a first placement step 12, and a first grate 13 is placed inside the first placement step 12. The top opening of the water storage tank 16 is provided with a second placement step 18, and a second grate 19 is placed inside the second placement step 18. One end of the water supply pipe 17 inserted into the water storage tank 16 is fixedly connected to an isolation net frame 20.

[0034] The space above the groove 6 is isolated by the first grate 13, the space above the water storage tank 16 is isolated by the second grate 19, and the water inlet of the water pipe 17 is isolated by the isolation mesh frame 20, thereby effectively reducing large impurities.

[0035] The working principle of this utility model is as follows:

[0036] In use, the masonry blocks 5 are assembled on the slope base layer 2 to form a stepped layer 3. At the same time, the limiting pins 21 pass through the insertion holes 15 and countersunk holes 14 to form positioning and limitation. At this time, greening can be planted in the planting trough 7. When there is water on the masonry blocks 5, the water will flow down the slope in the planting trough 7 and the turning trough 8. The water in the turning trough 8 flows into the groove 6 through the slope of the drainage trough 9 and is collected. When the water is on the masonry blocks 5, it will slide down into the drainage trough 9, and then flow through the drainage trough. The water from slope 9 is collected in groove 6. The water in groove 6 is discharged into the planting trough 7 below through the drain hole 10. The L-shaped baffle 11 blocks the water draining from the drain hole 10 to prevent the water from draining too quickly and causing the water column to form a parabola across the planting trough 7. The water is collected and stored at the bottom by the water storage tank 16. The water is pumped upward by the water pump 22 and the water pipe 17, thus forming a circulating irrigation effect, which makes it convenient to replenish water to the planting trough 7.
