Technical Field

[0001] This utility model relates to the field of drainage devices, and more specifically, to a drainage structure and a rainwater collection well. Background Technology

[0002] In existing technologies, rainwater collection wells are usually quite deep and the inner walls typically require a high degree of flatness, which places high demands on the precision of plastering. When operators perform plastering on the inner walls, they need to reach their hands or tools into the well to work, which limits the operating space and significantly increases the difficulty of construction. As a result, plastering is often inadequate and the quality is substandard. Utility Model Content

[0003] To address the shortcomings of existing technologies, a drainage structure and rainwater collection well are provided. This device can achieve a smooth surface on the inner wall of the rainwater collection well without plastering.

[0004] To achieve the above objectives, the following technical solution is provided: a drainage structure, comprising a main body and an inner lining; One end of the main body is provided with a groove, which is used to collect water and guide the flow of water; The inner lining is inserted into the main body and fixedly connected to the main body; The inner side of the liner is smooth.

[0005] In a further optimization of this utility model, the inner lining is fixedly connected to the main body by pouring cement mortar.

[0006] In a further optimization of this utility model, cement mortar is poured through the gap between the inner lining and the main body, and the inner lining and the main body are fixedly connected.

[0007] In a further optimization of this utility model, the gap between the inner lining and the main body is completely filled by cement mortar, and the inner lining and the main body are fixedly connected.

[0008] In a further optimization of this invention, the inner lining is made of PVC material.

[0009] In a further optimization of this utility model, a protective layer is also laid at the bottom of the main body, which is used to prevent sewage from flowing into the concrete base.

[0010] A further optimization of this invention is that the surface of the protective layer is smooth.

[0011] In a further optimization of this invention, the protective layer is a ceramic tile.

[0012] In a further optimization of this utility model, the main body is provided with a first through hole, and the inner liner is provided with a second through hole at the position corresponding to the first through hole.

[0018] Reference numerals: 1. Main body; 11. Groove; 12. First through hole; 2. Inner liner; 21. Second through hole; 3. Protective layer; 4. Filter element. Detailed Implementation

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "upper," and "lower" used in the following description refer to directions in the accompanying drawings, and the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0020] Reference Figure 1-3 As shown, a drainage structure includes a main body 1 and an inner liner 2; One end of the main body 1 is provided with a groove 11, which is used to collect water and guide the flow of water; The inner liner 2 is inserted into the main body 1 and is fixedly connected to the main body 1; The inner side of the liner 2 is smooth.

[0021] The inner lining 2 is inserted into the groove 11 of the main body 1, and its bottom abuts against the bottom of the groove 11. The inner lining 2 is fixedly connected to the groove 11 by means such as sealant, expansion bolts and cement mortar pouring. The smooth inner surface of the inner lining 2 directly replaces the traditional plastering process. When water flows through the groove 11 of the main body 1, the smooth inner wall of the inner lining 2 reduces the frictional resistance of the water flow and guides the water flow in a directional manner. This design eliminates the plastering process inside the well, eliminates the problem of uneven plastering, and directly ensures the smoothness of the inner wall.

[0022] Preferably, the inner lining 2 is fixedly connected to the main body 1 by pouring cement mortar.

[0023] Cement mortar is poured into the gap between the outer wall of the inner lining 2 and the inner wall of the groove 11, or cement mortar is poured into the inner lining 2. The cement mortar can be left at the bottom of the inner lining 2 or flow into the groove 11 from the bottom gap. The cement mortar cures and fixes the inner lining 2 and the main body 1. This connection method makes the connection between the inner lining 2 and the main body 1 tighter and enhances the overall compressive strength of the structure. At the same time, the cement mortar fills at least part of the gaps to ensure the stability of the connection between the inner lining 2 and the main body 1.

[0024] Preferably, the cement mortar is poured through the gap between the inner lining 2 and the main body 1, and the inner lining 2 and the main body 1 are fixedly connected.

[0025] The cement mortar fills at least part of the gap to ensure that the inner lining 2 does not move relative to the main body 1. After the cement mortar cures, it generates radial expansion force to make the outer wall of the inner lining 2 form an interference fit with the inner wall of the groove 11 of the main body 1.

[0026] Preferably, the gap between the inner liner 2 and the main body 1 is completely filled by cement mortar, and the inner liner 2 and the main body 1 are fixedly connected.

[0027] The cement mortar completely fills the gaps to form a connection without internal voids. At the same time, the completely filled mortar forms a seepage barrier, which blocks water from flowing into the mortar connection and thus flows into the inner lining 2.

[0028] Preferably, the inner liner 2 is made of PVC material.

[0029] The PVC lining 2 is hydrophobic, making it difficult for dirt to adhere and accumulate; it is also elastic, which can avoid the risk of cracking through slight deformation; PVC also has acid and alkali resistance, ensuring long-term stability in the complex composition of rainwater.

[0030] Preferably, a protective layer 3 is also laid at the bottom of the main body 1, which is used to prevent sewage from flowing into the concrete base.

[0031] like Figure 2 As shown, the protective layer 3 forms a physical isolation layer, preventing sewage from seeping down and corroding the concrete base; it can also resist the erosion and wear of sand and gravel.

[0032] Preferably, the surface of the protective layer 3 is smooth.

[0033] The protective layer 3 is smooth, which reduces the accumulation of debris on the protective layer 3 that cannot be washed away, while also facilitating water flow. It works in conjunction with the smooth inner wall of the inner lining 2 to synergistically improve drainage.

[0034] Preferably, the protective layer 3 is a ceramic tile.

[0035] The protective layer 3 is made of ceramic tiles. The edges of the ceramic tiles abut against the inner wall of the inner lining 2, and epoxy resin can be used to fill the joints of the ceramic tiles to form a continuous sealing surface. The ceramic tiles are completely laid on the bottom of the inner lining 2 to form a complete sealing surface at the bottom of the inner lining 2.

[0036] Preferably, the main body 1 is provided with a first through hole 12, and the inner liner 2 is provided with a second through hole 21 at the position corresponding to the first through hole 12.

[0037] like Figure 1 As shown, the first through hole 12 and the second through hole 21 form a through channel, allowing external water to flow through the second through hole 21 and the first through hole 12 in sequence and flow into the discharge point. When the cement mortar is poured for the main body 1, the first through hole 12 and the second through hole 21 need to be sealed. After the cement mortar has solidified, the sealing material is removed, allowing the first through hole 12 and the second through hole 21 to pass through.

[0038] A rainwater well includes a drainage structure and a filter element 4 installed on the drainage structure, wherein the drainage structure adopts any of the above-mentioned drainage structures.

[0039] like Figure 1 As shown, the filter element 4 is installed at the opening of the main body 1 by means of snaps, bolts or abutments. The filter element 4 intercepts solid impurities and reduces the impurities from entering the inner liner 2, thus preventing blockage and discharge problems.

[0040] The above are merely preferred embodiments of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are within its protection scope. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within its protection scope.
