Description

Technical Field

[0001] This utility model belongs to the technical field of sidewall drainage structure, and more specifically, it relates to a sidewall drainage structure. Background Technology

[0002] Sidewall drainage structures are drainage facilities installed on the sidewalls of structures such as tunnels and retaining walls. They typically consist of inclined drainage holes, filter layers, and drainage pipes. The drainage holes penetrate the structure to the surrounding rock or soil, the filter layer prevents silt blockage, and water flows through the holes into drainage channels for discharge. This effectively reduces water pressure inside the structure, prevents seepage damage, and ensures project stability. It is widely used in underground engineering, slope protection, and other applications.

[0003] To ensure the normal use of tunnels, construction workers need to excavate corresponding drainage structures within the tunnels. However, most of the current drainage structures are simple drainage channels. With prolonged use, this can easily lead to excessive lateral soil pressure on the inner walls, causing the drainage channels to collapse. In addition, the sewage discharged into the tunnels contains a large amount of gravel, leaves, or branches, which can easily cause blockages in the entire drainage structure.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings, and provide a side wall drainage structure in order to achieve a more practical purpose. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a sidewall drainage structure, which is achieved by the following specific technical means: A sidewall drainage structure includes a drainage trough, a base soil layer at the bottom of the drainage trough, a filter layer at the top of the base soil layer, drainage boards on both sides of the inner wall of the drainage trough, a baffle plate at the opening of the drainage trough, a plurality of ventilation holes at the top of the baffle plate, and a through groove on one side of the inner wall of the drainage trough, through which a drainage pipe is connected.

[0006] Furthermore, the surface of the drainage plate is provided with a continuous wavy embossed pattern, wherein the raised portion faces the sidewall of the drainage channel.

[0007] Furthermore, the drainage plate has a drainage cavity on the side adjacent to the drainage channel.

[0008] Furthermore, the interior of each drainage trough is equipped with a waterproof membrane.

[0009] Furthermore, the entire drain pipe is made of high-density polyethylene.

[0010] Compared with the prior art, the present invention has the following beneficial effects: In this invention, the setting of the baffle plate and drainage cavity can effectively provide a continuous, stable, and large cross-sectional void space, which can quickly collect water that has seeped from the geotextile and guide the water flow by gravity. The setting of the baffle plate and vent holes can effectively filter impurities in the water flow and prevent it from clogging. Attached Figure Description

[0014] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0015] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0016] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Example: As attached Figure 1 To be continued Figure 2 As shown: This utility model provides a sidewall drainage structure, including a drainage trough 1, a base soil 2 at the bottom of the drainage trough 1, a filter layer 3 at the top of the base soil 2, drainage boards 4 on both sides of the inner wall of the drainage trough 1, a baffle 5 at the opening of the drainage trough 1, a plurality of ventilation holes 6 at the top of the baffle 5, a through groove 7 on one side of the inner wall of the drainage trough 1, and a drainage pipe 8 connected to the drainage trough 1 through the through groove 7.

[0018] The surface of the drainage plate 4 is provided with a continuous wavy embossed pattern, with the raised part facing the side wall of the drainage trough 1, which can effectively guide the direction of water flow.

[0019] Among them, the drainage board 4 has a drainage cavity 9 on one side adjacent to the drainage trough 1. The drainage cavity 9 can effectively provide a continuous, stable, large cross-section void space, which can quickly collect water that seeps from the geotextile and guide the water flow by gravity.

[0020] The interior of each drainage trough 1 is equipped with a waterproof membrane, which can effectively improve the service life of the entire drainage structure.

[0021] Among them, the drainage pipe 8 is made of high-density polyethylene. High-density polyethylene is highly flexible, corrosion-resistant, environmentally friendly and non-toxic, and will not have an impact on the environment.

[0022] The working principle of this embodiment is as follows: When this utility model is used, a base soil 2 is laid at the bottom of the drainage trough 1, a filter layer 3 is set at the top, and drainage boards 4 are installed on both sides of the inner wall. The continuous wavy concave-convex pattern on the surface of the drainage board 4 and the raised part facing the side wall of the drainage trough 1 can effectively guide the direction of water flow. The drainage cavity 9 opened on the side adjacent to the drainage trough 1 can provide a continuous, stable, and large cross-sectional gap space, which can quickly collect infiltrated water and guide the water flow by gravity. The top of the trough opening baffle 5 has a vent hole 6. A waterproof membrane is set inside the drainage trough 1 to improve the overall service life. The high-density polyethylene drainage pipe 8 connected to one side of the inner wall through the through groove 7 has excellent flexibility, corrosion resistance and environmental protection and non-toxicity. The whole realizes the effect of efficiently guiding and collecting water flow, improving structural durability and environmental protection and harmlessness.
