Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy engineering slope protection, in particular to a water conservancy prefabricated block slope protection structure. Background Art

[0002] Water conservancy projects are projects built to control and allocate natural surface water and groundwater to achieve the purpose of eliminating harm and promoting benefits. They are also called water projects. Water is a valuable resource that is indispensable to human production and life, but its natural state does not fully meet human needs. Only by building water conservancy projects can we control water flow, prevent floods and waterlogging disasters, and regulate and distribute water to meet people's needs for water resources in life and production. Water conservancy projects include slope protection, etc. In order to play the role of anti-slip, anti-cracking and wave suppression on the water conservancy slope protection, prefabricated blocks need to be used to lay on the water conservancy slope protection.

[0003] Common hydraulic prefabricated block slope protection structures are usually concrete blocks, and the surface usually has raised horizontal stripes. They will be evenly laid on the slope of the hydraulic slope protection, and adjacent prefabricated blocks will fit together. This is a common hydraulic prefabricated block slope protection structure and its use method. The traditional hydraulic prefabricated block slope protection structure is easily loosened due to the influence of gravity when laid flat on the slope of the slope protection. It may slide off the slope protection after long-term use, thus failing to protect the slope. Some hydraulic prefabricated block slope protection structures improve the connectivity between the prefabricated block and the hydraulic slope protection by adding plug-in blocks to the prefabricated blocks and inserting the plug-in blocks into the interior of the hydraulic slope protection, thereby avoiding the phenomenon of the prefabricated blocks sliding off the hydraulic slope protection. However, this method, due to the large number of plug-in blocks corresponding to the prefabricated blocks, will increase the cost commission, disturb the soil, destroy the original soil structure, and increase the difficulty of construction. It requires more construction equipment and manpower investment, affecting the construction progress. For this reason, a hydraulic prefabricated block slope protection structure is proposed.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

Among them, the fixed structure can use an existing structure, such as a plug-in block, and in this embodiment, it is preferred to use a plug-in barrel 13.

[0023] The above-mentioned hydraulic prefabricated block slope protection structure, when the prefabricated group is laid on the slope protection, between adjacent prefabricated blocks, the first positioning block and the first clamping block are respectively inserted into the corresponding first positioning groove and the inside of the first clamping groove, and the second positioning block and the second clamping block are respectively inserted into the corresponding second positioning groove and the second clamping groove for connection, and fixed by a fixing structure. On the one hand, multiple groups of prefabricated blocks are connected into one, and only some of the prefabricated blocks need to be fixed to ensure the stability of the prefabricated group, and avoid the phenomenon of damaging the soil structure and increasing the difficulty of construction due to too many fixing structures; on the other hand, multiple groups of prefabricated blocks are connected, and the overall anti-collision is increased due to the reason of being connected into blocks, which plays a role in slope protection.

[0024] In one implementation, the prefabricated block is provided with a plug hole 12, and some of the plug holes are provided with a plug tube 13, one end of the plug tube passes through the plug hole and is located in the slope protection, wherein the plug tube can also be a ground nail, a peg, etc. In this embodiment, the plug tube preferably uses the following structure: Figure 4 The top of the plug-in tube is threadedly connected to a limit ring 14, the bottom of the plug-in tube is provided with a side groove 15, the inside of the plug-in tube is provided with a guide column 16, the top of the guide column is exposed outside the plug-in tube, the bottom of the guide column is provided with a spring 18, and a clamping rod 16 is hinged at a position corresponding to the side groove on the plug-in tube; in the original state, the end of the clamping rod that is not connected to the guide column passes through the side groove, and when the guide column is pressed down, the clamping rod rotates into the side groove or the plug-in tube. After a plurality of prefabricated blocks are connected to form a prefabricated group and laid on the slope protection, the guide column is pressed down to compress the spring. During the pressing process, the clamping rod 16 rotates and gradually enters the side groove or even retracts into the plug-in tube. After being inserted into the interior of the slope protection, the guide column is released. The guide column rises under the action of the spring, and the clamping rod extends through the side groove to the outside of the plug-in tube 13 and abuts against the inside of the slope protection 1. Compared with the traditional conical plug-in block, the present structure has better connectivity and stability. In actual production, the connection between the clamping rod and the guide column can be provided with a torsion spring or the clamping rod can be directly connected to the clamping rod through a spring sheet.

Figure 4 A protruding column is provided at the bottom end of the guide column, the spring is sleeved on the protruding column, and a receiving groove for accommodating the protruding column is provided at the bottom end of the plug-in tube. The diameter of the spring is larger than the receiving groove, and the diameter of the protruding column is less than or equal to the receiving groove. Preferably, both sides of the guide column are hinged with a clamping rod.

[0026] As an embodiment, the first clamping block is an L-shaped clamping block, one end of which is connected to the prefabricated block; there are two first clamping blocks, which are symmetrically arranged with the first positioning block as a reference; the second clamping block is a T-shaped clamping block, which is connected to the prefabricated block; there are two second clamping blocks, which are symmetrically arranged with the second positioning block as a reference. This structure forms clamps on both sides of the blocks through the arrangement of L-shaped and T-shaped clamping blocks, which can be easily connected and mechanized. In addition, this structure can only be lifted, disassembled and assembled, and cannot be disassembled and assembled by pulling in all directions, thereby ensuring the stability of the connection and avoiding self-separation, which leads to the formation of through seams.

[0027] As an implementation method, see Figure 3The top of the prefabricated block 3 is evenly provided with anti-skid grooves 19, and reinforcing ribs 20 are installed at the front and rear ends of the center positions on both sides of the prefabricated block 3. The prefabricated block 3 plays the role of anti-skid and enhancing its own hardness through the anti-skid grooves 19 and the reinforcing ribs 20.
