Description

Technical Field

[0001] The utility model relates to the technical field of concrete, in particular to an anti-blocking structure for permeable concrete. Background Technique

[0002] Concrete structures can be divided into reinforced concrete structures and prestressed concrete structures according to their structures. Concrete can also be divided into various types according to its functions, including permeable concrete structures. The water on the permeable concrete structure can penetrate to the ground, thus promoting the water cycle to a certain extent. The application of permeable concrete is relatively wide.

[0003] Chinese Patent Publication No. CN221000434U discloses an anti-blocking permeable concrete structure, including a foundation, a concrete base layer fixedly connected to the top of the foundation, a fixed frame fixedly connected to the top of the concrete base layer, a frame cover embedded and connected to the top of the fixed frame, an opening formed in the frame cover, a permeable mesh plate fixedly connected in the opening, a mesh groove arranged at the bottom of the frame cover, and the frame cover and the mesh groove are fixedly connected by a first fixing bolt and a second fixing bolt respectively, so that the above structure can be disassembled, facilitating personnel to clean and replace the filtering components in the structure.

[0004] However, the above technical solution has the following problems: Workers generally place the fixed frame first and then pour permeable concrete. During the flowing process of the permeable concrete, the top of the fixed frame will be completely covered. When opening the frame cover, the structure of the permeable concrete will be damaged, which is likely to affect the service life of the permeable concrete and the user experience. Content of the Utility Model

[0005] The purpose of the utility model is to address the problems in the background technique and propose an anti-blocking structure that blows open the blocked sundries by flowing the airflow in the intake pipe to the air outlet frame and the permeable layer in sequence, thereby ensuring the water permeability of the permeable concrete without reducing its service life.

[0006] The technical solution of the utility model, an anti-blocking structure for permeable concrete, includes: a soil base, on which an installation layer, a diversion layer and a permeable layer are sequentially arranged, and a plurality of drain pipes and intake pipes are arranged in a staggered manner on the installation layer; an anti-blocking component, which is arranged on the diversion layer and communicated with the intake pipe, and the anti-blocking component includes an air outlet frame arranged on the diversion layer, a plurality of pairs of fixed rings oppositely arranged on the air outlet frame, a plurality of stepped guide rods arranged annularly between the plurality of pairs of fixed rings, a spring arranged on each of the plurality of stepped guide rods, and a plurality of sliding plates arranged on the plurality of stepped guide rods.

[0007] Preferably, the top end of the air outlet frame has a plurality of exhaust grooves and air outlet holes. The plurality of air outlet holes are located on the side walls of the plurality of exhaust grooves. The plurality of air outlet holes are all communicated with the air inlet pipe, and multiple pairs of fixing rings are respectively located at the plurality of air outlet holes.

[0008] Preferably, the cross-sectional area of the lower half of the air outlet hole gradually increases as the distance from the nearest water-permeable layer decreases.

[0009] Preferably, the diversion layer includes a diversion layer body part and a plurality of support frame parts uniformly arranged on the diversion layer body part. The tops of the plurality of support frame parts are located on the same plane as the top end of the air outlet frame.

[0010] Preferably, a plurality of diversion grooves are uniformly distributed at the top end of the diversion layer body part. The plurality of diversion grooves are respectively and correspondingly communicated with the plurality of drain pipes, and the plurality of support frame parts are respectively located at the plurality of diversion grooves.

[0011] Preferably, a plurality of water guide pipes are arranged on the diversion layer. The plurality of water guide pipes are respectively arranged on the plurality of air outlet frames. The two ends of the water guide pipes are respectively communicated with the water-permeable layer and two adjacent drain pipes.

[0012] Compared with the prior art, the utility model has the following beneficial technical effects:

[0013] When the utility model is in use, an air pump sends high-speed air flow into the air inlet pipe. The high-speed air flow flows into the air outlet frame. The air flow pushes the sliding plate to move. Then the air flow is sent from the air outlet frame into the water-permeable layer. The sundries accumulated in the water-permeable layer will be loosened under the action of the air flow, so as to solve the blockage in the water-permeable layer, ensure the structural strength of the water-permeable layer, and improve the service life of the water-permeable layer. The air outlet holes with side openings maximize the foot feeling of the user when using permeable concrete, thus avoiding inconsistent elasticity at multiple places of the permeable concrete head.

Detailed Embodiment

[0018] Example 1

[0019] As Figures 1 - 3 shown, a clogging prevention structure of permeable concrete proposed in this embodiment includes a soil base 1 and a clogging prevention component. An installation layer 2, a diversion layer 3, and a permeable layer 4 are sequentially arranged on the soil base 1. A plurality of drain pipes 5 and air inlet pipes 6 are staggered on the installation layer 2, and an air pump is connected to the air inlet pipe 6.

[0020] The clogging prevention component is arranged on the diversion layer 3 and is connected to the air inlet pipe 6. The clogging prevention component includes an air outlet frame 7 arranged on the diversion layer 3, a plurality of pairs of fixed rings 8 oppositely arranged on the air outlet frame, a plurality of stepped guide rods 9 arranged between each pair of fixed rings 8 along the ring shape, a spring 10 arranged on each of the plurality of stepped guide rods 9, and a plurality of sliding plates 11 arranged on the plurality of stepped guide rods 9.

[0021] A plurality of water guide pipes 12 are arranged on the diversion layer 2. The plurality of water guide pipes 12 are respectively arranged on the plurality of air outlet frames 7. Both ends of the water guide pipe 12 are respectively connected to the permeable layer 4 and two adjacent drain pipes 5. The side of the water guide pipe 12 is grooved. The plane of the air outlet frame 7 gradually slopes upward from both sides of the water guide pipe 12 in the corresponding direction, so that the water flow falling on the air outlet frame 7 flows into the water guide pipe 12. The water guide pipe 12 gradually slopes downward from the middle to both end faces, so as to make the water flow flow into the drain pipe 5 under the action of its own gravity, thereby improving the drainage efficiency of the permeable concrete in rainy days.

[0022] When this embodiment is used, the air pump sends high-speed air flow into the air inlet pipe 6. The high-speed air flow flows into the air outlet frame 7. The air flow pushes the sliding plate 11 to move, and then the air flow is sent from the air outlet frame 7 into the permeable layer 4. The sundries accumulated in the permeable layer 4 will be loosened under the action of the air flow, so as to solve the blockage in the permeable layer 4, ensure the structural strength of the permeable layer 4, and extend the service life of the permeable layer 4.

[0023] Example 2

[0024] As Figure 2 shown, a clogging prevention structure of permeable concrete proposed in this embodiment, compared with Example 1, in this embodiment, the top end of the air outlet frame 7 has a plurality of exhaust grooves and air outlet holes 71. The plurality of air outlet holes 71 are located on the side walls of the plurality of exhaust grooves. The plurality of air outlet holes 71 are all connected to the air inlet pipe 6. Each pair of fixed rings 8 is respectively located at the plurality of air outlet holes 71. The cross-sectional area of the lower half of the air outlet hole 71 gradually increases as the distance from the nearest permeable layer 4 decreases. Thus, when it rains, the water flow can flow to the bottom end of the exhaust groove under the action of its own weight, thereby preventing the water flow from flowing into the air inlet pipe 6 and reducing the probability of internal damage of the air inlet pipe 6.

[0025] In this embodiment, the airflow flows from multiple air outlets 71 into the water-permeable layer in the exhaust groove. When pouring the water-permeable concrete head, the side-opening air outlets 71 will not be completely blocked by the air outlet frame 7, and the side-opening air outlets 71 maximize the foot feeling of the user using the water-permeable concrete, thus avoiding inconsistent elasticity at multiple places of the water-permeable concrete head.

[0026] Embodiment Three

[0027] As Figure 1 shown, a water-permeable concrete anti-blocking structure proposed in this embodiment. Compared with Embodiment One, in this embodiment, the diversion layer 3 includes a diversion layer main body part 31 and a plurality of support frame parts 32 uniformly arranged on the diversion layer main body part 31. The tops of the plurality of support frame parts 32 and the top of the air outlet frame 7 are located on the same plane. The distance between every two adjacent support frame parts 32 is less than the width of the sole of a child over five years old, so as to ensure the moving experience. A plurality of diversion grooves 311 are uniformly distributed at the top of the diversion layer main body part 31. The plurality of diversion grooves 311 are in one-to-one correspondence and communication with the plurality of drain pipes 5. The plurality of support frame parts 32 are respectively located at the plurality of diversion grooves 311.

[0028] In this embodiment, the plurality of support frame parts 32 support the structure of the water-permeable concrete, avoiding inconsistent elasticity at different positions due to inconsistent thickness of the water-permeable concrete at multiple positions, thus ensuring the movement or walking experience of pedestrians.

[0029] The above has described in detail the embodiments of the present invention in conjunction with the accompanying drawings. However, the present invention is not limited to this. Within the scope of knowledge possessed by those skilled in the art to which it pertains, various changes can be made without departing from the gist of the present invention.
