Description

Technical Field

[0001] This application belongs to the technical field of drainage construction, and particularly relates to a drainage trough and a drainage structure. Background Art

[0002] In the siphon drainage construction of roofs and basement roofs, on-site construction personnel usually use waterproof materials to bond and fix a semi-open drainage trough body. Using a waterproof bonding material as the bottom strengthening layer of the drainage channel will accelerate the aging and wear of the waterproof bonding material, and over time, it will lose its function as a drainage channel, resulting in a short service life of the drainage structure. The waterproof bonding material used to fix the drainage trough has no root penetration resistance, and there is a problem that the roots are likely to penetrate and damage the bottom waterproof layer and structural layer at the connection between the drainage trough and the drainage board, increasing the risk of later leakage. Summary of the Invention

[0003] The purpose of this application is to provide a drainage trough and a drainage structure, which are beneficial to improving the waterproof effect.

[0004] To achieve the above purpose, on the one hand, this application provides a drainage trough, which includes:

[0005] A drainage trough body with a longitudinally extending drainage cavity provided therein; and

[0006] A bottom plate, which is located below the drainage trough body and forms an integral part with the drainage trough body. The bottom plate includes a cover part and two overlapping parts. The cover part seals the lower opening of the drainage cavity, and the two overlapping parts respectively extend laterally outward from the two transverse ends of the cover part and are used for overlapping with the drainage board.

[0007] In some specific embodiments, the lateral extension length of the overlapping part is greater than or equal to 80 mm.

[0008] In some specific embodiments, plug-in structures capable of plugging and matching are formed at both longitudinal ends of the drainage trough body. At one longitudinal end of the drainage trough, the drainage trough body extends longitudinally outward and extends to the longitudinal outside of the overlapping part. At the other longitudinal end of the drainage trough, the overlapping part extends longitudinally outward and extends to the longitudinal outside of the drainage trough body, so that the overlapping parts can overlap longitudinally when two drainage troughs are plugged and connected.

[0009] In some specific embodiments, the drainage trough body is welded to the bottom plate; alternatively, the drainage trough body and the bottom plate are integrally formed.

[0010] In some specific embodiments, an adhesive layer is provided on the bottom surface of the bottom plate.

[0011] In some specific embodiments, a separator film is provided on the outer side of the adhesive layer.

[0012] In some specific embodiments, the bottom plate is a HDPE sheet; and / or, the thickness of the bottom plate is greater than 0.5 mm and less than or equal to 2 mm; and / or, a plurality of drain openings communicating with the drain cavity and arranged at intervals in the longitudinal direction are provided on the lateral side of the drain trough body along the transverse direction.

[0013] The second aspect of the present application further provides a drainage structure, which includes:

[0014] A drainage board; and

[0015] The above-mentioned drain trough, and the edge part of the drainage board is welded and lapped or adhesively lapped with the lapping part.

[0016] In some specific embodiments, the height of the top surface of the drainage diversion part of the drainage board is higher than the height of the edge part of the drainage board. The drainage structure further includes a drainage mesh pad, and the drainage mesh pad is arranged between the drainage diversion part and the drain trough body and above the edge part of the drainage board.

[0017] In some specific embodiments, a drainage board geotextile is provided on the top surface of the drainage diversion part of the drainage board. The drainage structure further includes a drain trough geotextile, and the drain trough geotextile is laid above the drain trough and lapped with the drainage board geotextile, and the drainage mesh pad is located below the lapping section between the drainage board geotextile and the drain trough geotextile.

[0018] Through the above technical solutions, since a bottom plate is additionally provided at the bottom of the drain trough body, the bottom plate can cover the drain cavity of the drain trough body and lap with the drainage board, so that the drainage structure has a physical puncture resistance performance, can effectively prevent plant roots from penetrating and damaging the bottom waterproof layer and the structural layer, and reduce the risk of later leakage. And, since the bottom plate of the drain trough and the drainage board can lap to form a complete drainage channel, the structural strength of the drainage structure is high, which is beneficial to increasing the service life of the drainage channel and ensuring the drainage effect and waterproof effect of the drainage channel. In addition, the drain trough body and the bottom plate are formed as an integral part, with good structural reliability and no need for installation, making it more convenient to use.

[0019] Other features and advantages of the embodiments of the present application will be described in detail in the subsequent specific embodiment part. Description of the Drawings

[0034] The following details the specific embodiments of the present application in conjunction with the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present application and are not used to limit the present application.

[0035] In the siphonic drainage construction of the roof and the basement top slab, on-site construction workers usually use waterproof materials to bond and fix the semi-open drainage trough. Since this construction method uses waterproof bonding materials as the bottom reinforcement layer of the drainage channel, it will accelerate the aging and wear of the waterproof bonding materials, and over time, it will lose its function as a drainage channel. Moreover, when constructing the fixed drainage trough on-site, if the bonding surface of the trough encounters clear water or dust, the bonding effect may be poor, resulting in the displacement of the drainage trough during the later backfilling of soil, affecting the drainage effect. When encountering a large-span top slab, the drainage trough is usually hundreds of meters long. At this time, it is generally impossible for construction workers to accurately position the drainage trough. The excessively long connection distance may cause the drainage trough to be crooked and deviate greatly from the actual position, thus affecting the construction quality. If the base surface condition is not ideal and it is difficult to fix the drainage trough well, the methods of using primer, wet laying method and compounding with non-curing materials are usually adopted to improve the bonding ability between the waterproof bonding materials and the base surface and then bond the drainage trough. Due to the cumbersome and complex procedures, the construction period will be prolonged. In addition, the waterproof bonding materials used to fix the drainage trough have no root penetration resistance, and the lap joint between the drainage trough and the drainage board cannot be sealed firmly. Therefore, there is a risk of root penetration damaging the bottom waterproof layer and the structural layer here, increasing the risk of later leakage.

[0036] In view of this, as Figure 1 , Figure 2 and Figure 4 shown, on the one hand, the present utility model provides a drainage trough, which includes a drainage trough body 1 and a bottom plate 2. A drainage cavity 11 extending longitudinally is arranged in the drainage trough body 1. The bottom plate 2 is located below the drainage trough body 1 and forms an integral part with the drainage trough body 1, that is, the drainage trough body 1 and the bottom plate 2 are formed as an integral part at the factory and no further assembly is required, which is convenient for construction.

[0037] The bottom plate 2 includes a cover part 21 and two overlapping parts 22. The cover part 21 seals the lower opening of the drainage cavity 11. The two overlapping parts 22 correspondingly extend outward horizontally from the transverse two ends of the cover part 21 and are used for overlapping with the drainage board 3. In this way, on-site workers can directly install the drainage board 3 on the bottom plate 2, and the overlapping parts 22 can be welded / bonded to the drainage board 3 by welding / bonding to form an integrated complete drainage channel.

[0038] Since the bottom plate 2 is a sheet with a complete plate surface and is provided with a self - contained overlapping part 22 for welding / adhering to the large - area drainage plate 3, it is not only convenient for construction, but also enables the drainage structure to have an excellent effect of preventing root penetration, reducing the risk of later leakage. Moreover, since the bottom plate 2 and the drainage trough body 1 are an integral part, the overall structural strength of the drainage trough is high, which is beneficial to increasing the service life of the drainage channel and making it more reliable. In addition, the drainage trough body and the bottom plate are delivered to the site as an integral part, and no other tools or auxiliary materials are required for installation, and there are no requirements for the professionalism of personnel, and the operation is simple and feasible.

[0039] Among them, the bottom plate 2 can be an HDPE sheet, which has the physical root - penetration resistance performance. The integrated sheet can effectively prevent plant roots from penetrating and damaging the bottom waterproof layer and the structural layer, reduce the risk of later leakage, and can greatly enhance the compressive strength of the siphon drainage trough body. Among them, in order to balance the structural strength and manufacturing cost of the bottom plate 2, the thickness of the bottom plate 2 can be set to be greater than 0.5 mm and less than or equal to 2 mm. Preferably, the thickness of the bottom plate 2 can be set to 1 mm.

[0040] Optionally, the drainage trough body 1 and the bottom plate 2 can be connected by welding to form an integral part; or, the drainage trough body 1 and the bottom plate 2 are integrally formed parts, such as integrally injection - molded parts.

[0041] Optionally, in order to improve the overlapping effect between the overlapping part 22 and the drainage plate 3, the extending length of the overlapping part 22 in the transverse direction is greater than or equal to 80 mm. Preferably, the extending length of the overlapping part 22 in the transverse direction is greater than or equal to 100 mm. And, in order to ensure the drainage effect of the drainage trough, the length of the cover part 21 in the transverse direction can be greater than or equal to 150 mm, preferably greater than or equal to 200 mm.

[0042] Optionally, as Figure 1 and Figure 4 shown, a plurality of drainage ports 12 that are communicated with the drainage cavity 11 and arranged at intervals in the longitudinal direction are provided on the lateral side of the drainage trough body 1 in the transverse direction.

[0043] In some specific embodiments, plug - in structures that can be plugged and matched are formed at both longitudinal ends of the drainage trough body 1. In order to further improve the root - penetration resistance performance of the drainage structure, as Figure 1 、 Figure 2 and Figure 3 shown, at one longitudinal end of the drainage trough, the drainage trough body 1 extends longitudinally outward and extends to the longitudinal outside of the overlapping part 22; at the other longitudinal end of the drainage trough, the overlapping part 22 extends longitudinally outward and extends to the longitudinal outside of the drainage trough body 1, so that the overlapping part 22 can overlap longitudinally when two drainage troughs are plugged and connected. Among them, when two drainage troughs are plugged and connected, the opposite ends of the overlapping parts 22 of the two drainage troughs overlap longitudinally and can be connected by welding or bonding.

[0044] In some specific embodiments, in order to greatly improve the construction efficiency of the drainage structure, an adhesive layer 23 is provided on the bottom surface of the bottom plate 2. The treatment of applying glue to the entire bottom surface of the bottom plate 2 can improve the construction convenience, construction efficiency, and ensure the construction quality compared with the traditional method of fixing the drainage groove with adhesive tape.

[0045] Optionally, in order to protect the adhesive layer 23, an isolation film 24 is provided on the outer side of the adhesive layer 23. When installing the drainage groove on the roof or the basement top plate, the construction worker then tears off the isolation film 24.

[0046] The second aspect of the present application also provides a drainage structure, as Figure 5 shown. This drainage structure includes a drainage board 3 and the above-mentioned drainage groove. The edge portion 31 of the drainage board 3 is welded and lapped or adhesively lapped with the lapping portion 22. In this way, an integrated and complete drainage channel can be formed for the drainage groove, increasing the service life of the drainage channel, ensuring the drainage effect of the drainage channel, effectively preventing the penetration of plant roots to damage the bottom waterproof layer and the structural layer, and reducing the risk of later leakage. Since the drainage structure of the present application includes the above-mentioned drainage groove, it also has all the technical effects brought by the above-mentioned drainage groove, so it will not be elaborated here.

[0047] In some specific embodiments, as Figure 5 shown, the height of the top surface of the drainage diversion portion 32 of the drainage board 3 is higher than the height of the edge portion 31 of the drainage board 3. The drainage structure further includes a drainage net pad 4. The drainage net pad 4 is arranged between the drainage diversion portion 32 and the groove body 1 of the drainage groove and above the edge portion 31 of the drainage board 3. In this way, the drainage net pad 4 is arranged at the lapping position between the drainage board 3 and the lapping portion 22, and the drainage net pad 4 can be used as a connecting gasket to ensure the smoothness of the drainage channel.

[0048] Optionally, as Figure 5 shown, a drainage board geotextile 33 is provided on the top surface of the drainage diversion portion 32 of the drainage board 3. The drainage structure further includes a drainage groove geotextile 5. The drainage groove geotextile 5 is laid above the drainage groove and lapped with the drainage board geotextile 33. The drainage net pad 4 is located below the lapping section between the drainage board geotextile 33 and the drainage groove geotextile 5. In this way, a drainage structure with a complete and reasonable structure can be formed. This drainage structure has good drainage and waterproof effects and a long service life.

[0049] In summary, the present application provides a drainage groove and a drainage structure. The drainage groove and the drainage structure have a bottom plate, with good drainage and waterproof effects; the bottom plate has a self-provided lapping portion that can be welded with the large-area drainage board, which can play a role in root penetration resistance, and the structure of applying glue to the bottom of the bottom plate can greatly improve the construction efficiency of the drainage groove.
