Spliced drain pipe brick

Abstract

This utility model discloses a spliced ​​drainage pipe brick, including a first arc-shaped brick and a second arc-shaped brick; after splicing and installation, it forms a pipe structure; the first arc-shaped brick has multiple permeable holes, which are conical in shape, with the diameter increasing from the outer arc side to the inner arc side of the first arc-shaped brick. First, a trench is excavated, then the lower side of the second arc-shaped brick is embedded in the soil layer for stability, and then the first arc-shaped bricks are covered one by one to form a complete drainage pipe. During rainy season, rainwater is collected on the upper layer of sand and gravel through surface runoff. The rainwater infiltrates and passes through the permeable holes into the drainage pipe, which further collects the water into an underground reservoir for later irrigation. The drainage pipe is constructed by splicing the upper and lower arc-shaped bricks. Later, when silt accumulates inside the pipe, the first arc-shaped brick can be opened and disassembled for easy cleaning of the internal silt, facilitating efficient rainwater collection.

Description

Technical Field

[0001] This utility model belongs to the field of functional brick technology, and in particular relates to a spliced ​​drainage pipe brick. Background Technology

[0002] Municipal sewage drainage pipes mostly use PE pipes and underground cement culverts. They collect mostly sewage, which needs to undergo a series of filtration and disinfection processes before it can be used. However, water used in parks and green belts does not require particularly clean filtration. Rain gardens can be set up to collect rainwater, which can be drawn from nearby sources for irrigation.

[0003] Therefore, rain gardens can be set up in parks and scenic areas to collect rainwater from heavy rainfall for later use in irrigating flowers and trees. Rainwater collection also prevents the formation of sewage pools. Most existing filtration systems use perforated pipe structures, which accumulate sediment inside the pipes due to the presence of silt in the rainwater, leading to blockages that are very difficult to clean. Utility Model Content

[0004] The purpose of this invention is to provide a modular drainage pipe brick to solve the problem of difficulty in cleaning silt and blockages in existing pipes.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A type of interlocking drainage pipe brick includes a first arc-shaped brick and a second arc-shaped brick; both the first arc-shaped brick and the second arc-shaped brick have semi-circular cross sections, the second arc-shaped brick is located at the bottom and the first arc-shaped brick is located on the top side, and the interlocking installation forms a pipe structure.

[0007] The first arc-shaped brick has multiple permeable holes, which are conical in shape and have an increasing diameter from the outer arc side to the inner arc side.

[0008] Furthermore, a first step is provided on one side of the second arc-shaped brick, and a second step is formed on the other side. The first and second steps of adjacent second arc-shaped bricks are matched to each other for lap joint installation of adjacent second arc-shaped bricks.

[0009] Furthermore, the first arc-shaped brick has a third step on its side, and the second arc-shaped brick has a fourth step that matches the third step. The first and second arc-shaped bricks are installed offset vertically, and the second arc-shaped brick has a limiting block in the center of the fourth step, while the first arc-shaped brick has a groove on its end side for matching the limiting block.

[0010] Furthermore, the second arc-shaped brick has support plates extending outwards on both sides.

[0011] This utility model has the following beneficial effects: The integrated drainage pipe is formed by connecting multiple sections end to end. Buried in low-lying areas of the garden, a trench is first excavated. Then, the lower side of the second arc-shaped brick is embedded in the soil layer for stability. Next, the first arc-shaped bricks are placed one by one to cover the second section, forming a complete drainage pipe. Finally, granular sand and gravel of a certain diameter are placed on top of the drainage pipe in the trench, acting as a filter layer. During rainy season, rainwater is collected on the top layer of sand and gravel through surface runoff. The rainwater infiltrates and passes through permeable holes into the drainage pipe, which further collects the water into an underground reservoir for later irrigation. The drainage pipe is constructed by splicing upper and lower arc-shaped bricks. Later, silt and sand accumulate inside the pipe. The first arc-shaped bricks can be opened and disassembled for easy cleaning of the internal silt and sand, facilitating efficient rainwater collection. Attached Figure Description

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] like Figure 1-4 As shown: A type of interlocking drainage pipe brick includes a first arc-shaped brick 1 and a second arc-shaped brick 2; the cross-section of the first arc-shaped brick 1 and the second arc-shaped brick 2 is semi-circular arc-shaped, the second arc-shaped brick 2 is located at the bottom, and the first arc-shaped brick 1 is located on the top side, forming a pipe structure after interlocking installation;

[0020] The first arc-shaped brick 1 has multiple permeable holes 11 arranged in a conical structure, with the diameter increasing from the outer arc side to the inner arc side of the first arc-shaped brick 1.

[0021] like Figure 4 As shown: Both the first and second curved bricks are made of cast concrete, and are joined together to form a single-section drainage pipe. The entire drainage pipe is formed by connecting multiple sections end to end, buried in the low-lying area of ​​the garden. First, a trench is excavated, then the lower side of the second curved brick is embedded in the soil layer for stability, and then the first curved bricks are covered one by one to form a complete drainage pipe. Finally, granular sand and gravel of a certain diameter are covered on the upper side of the corresponding drainage pipe in the trench, acting as a filter layer. During the rainy season, rainwater is collected on the upper layer of sand and gravel through surface runoff. The rainwater infiltrates and enters the drainage pipe through permeable holes, and the drainage pipe further collects the water into the underground reservoir for later irrigation.

[0022] The drainage pipe is made of upper and lower curved bricks. Later, when the inside of the pipe accumulates silt, the first curved brick can be opened and disassembled to facilitate the cleaning of the silt and facilitate efficient collection of rainwater.

[0023] like Figure 1 As shown: A first step 21 is provided on one side of the second arc-shaped brick 2, and a second step 22 is formed on the other side. Adjacent second arc-shaped bricks 2 are matched with the corresponding first step 21 and second step 22 for overlapping and butt joint installation. This ensures that the formed drainage pipes are at the same height, preventing the spliced ​​pipes from being misaligned.

[0024] The first arc-shaped brick 1 has a third step 12 on its side, and the second arc-shaped brick 2 has a fourth step 24 that matches the third step 12. This is used for limiting the installation between the first and second arc-shaped bricks. The first arc-shaped brick 1 and the second arc-shaped brick 2 are installed vertically staggered. The second arc-shaped brick 2 has a limiting block 23 at the center of the fourth step 24, and the first arc-shaped brick 1 has a groove 13 on its end side for matching the limiting block 23. This design provides better load-bearing capacity, and under load, the mating sides of adjacent second arc-shaped bricks are less likely to separate.

[0025] The second arc-shaped brick 2 has support plates 3 extending outwards on both sides, improving the stability of the bottom support.

[0026] These embodiments are selected and specifically described in this specification in order to better explain the principles and practical applications of this utility model, so that those skilled in the art can better understand and utilize this utility model.
