[0002] In the siphon drainage construction of roofs and basement roofs, on-site construction personnel usually use waterproof materials to bond and fix the semi-open drainage trough body. Using waterproof bonding materials as the bottom strengthening layer of the drainage channel will accelerate the aging and wear of the waterproof bonding materials, 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 materials used to fix the drainage trough have 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

At the other longitudinal end of the drainage trough body and the drainage trough bottom plate, the drainage trough bottom plate extends outward longitudinally and extends to the longitudinal outside of the drainage trough body, so that the drainage trough bottom plates can overlap with each other longitudinally when the two drainage troughs are plugged and connected;
[0010] And / or, the extending length of the overlapping portion along the transverse direction is greater than or equal to 80 mm.
[0011] In some specific embodiments, an adhesive layer is provided on the bottom surface of the bottom plate, and an isolation film is provided on the outer side of the adhesive layer;
[0012] And / or, the drainage trough bottom plate is made of HDPE sheet.

[0016] In some specific embodiments, the drainage trough body includes a cavity wall portion and two first buckle portions. The cavity wall portion defines the drainage cavity, and the two first buckle portions correspondingly extend laterally outward from the two bottom ends of the cavity wall portion along the transverse direction.

[0041] The specific embodiments of the present application will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only for the purpose of illustration and explanation of the present application, and are not intended to limit the present application.
[0042] In the siphon drainage construction of the roof and the basement top slab, on-site construction workers usually use a waterproof material to bond and fix the semi-open drainage trough body. Since this construction method uses a waterproof bonding material as the bottom strengthening layer of the drainage channel, it will accelerate the aging and wear of the waterproof bonding material, and over time, it will lose its function as a drainage channel. Moreover, when fixing the drainage trough on-site, if the bonding surface of the trough body encounters clear water or dust, the bonding effect may be poor, resulting in the displacement of the drainage trough body during the later backfilling, affecting the drainage effect. When encountering a large-span top slab, the drainage trough body is usually hundreds of meters long. At this time, construction workers generally cannot accurately position the drainage trough body, and the long connection distance may cause the drainage trough to be crooked, with a large deviation 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 a primer, wet laying method, and compounding with non-curing are usually adopted to improve the bonding ability between the waterproof bonding material and the base surface and then bond the drainage trough body. Since the process is cumbersome and complex, the construction period will be prolonged. In addition, the waterproof bonding material used to fix the drainage trough has no root penetration resistance, and the lap joint between the drainage trough and the drainage board cannot be firmly sealed. Therefore, there is a risk of root penetration damaging the bottom waterproof layer and the structural layer here, increasing the risk of later leakage.
[0043] In view of this, as Figure 1 , Figure 2 and Figure 4 shown, in the first aspect of the present invention, a new type of drainage trough bottom plate 2 is provided. The drainage trough bottom plate 2 includes a cover body part 21 with a lower open end covering the drainage cavity 11 and a lapping part 22 extending laterally outward from the two lateral ends of the cover body part 21. The lapping part 22 is used for lapping with the drainage board 3. In this way, on-site workers can directly install and fix the drainage trough body 1 on the drainage trough bottom plate 2, and the lapping part 22 can be welded / bonded to the drainage board 3 by welding / bonding to form an integrated and complete drainage channel.
[0044] In the second aspect of the present utility model, a novel drainage trough is provided. The drainage trough includes a drainage trough body 1 and the above-mentioned drainage trough bottom plate 2. A drainage cavity 11 extending longitudinally is provided inside the drainage trough body 1. The drainage trough bottom plate 2 is located below the drainage trough body 1 and is connected to the drainage trough body 1. In this way, the drainage trough body 1 can be fixed on the bottom plate. Since the drainage trough of the present application includes the above-mentioned drainage trough bottom plate, it also has all the technical effects brought by the above-mentioned drainage trough bottom plate, so it will not be elaborated here.
[0045] The drainage trough bottom plate 2 is a sheet material with a complete plate surface and can be an integrally formed part. Since the drainage trough bottom plate 2 is a sheet material with a complete plate surface and has a self - contained overlapping part 22 for welding / bonding with a 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. And because the drainage trough is provided with the drainage trough bottom plate 2 and is snap - connected to the drainage trough body 1, the overall structural strength of the drainage trough is high, which is beneficial to increasing the service life of the drainage channel and is more reliable. In addition, the drainage trough body and the bottom plate are assembled as finished product accessories and delivered to the site, which is convenient for transportation. And the drainage trough body and the bottom plate are set as snap - connections, and no other tools or auxiliary materials are required to complete the assembly, and there is no requirement for the professionalism of personnel, and the operation is simple and feasible.
[0046] Among them, the drainage trough bottom plate 2 can be an HDPE sheet material, which has physical root - penetration resistance. The integrated sheet material can effectively prevent plant roots from penetrating and damaging the bottom waterproof layer and structural layer, reduce the risk of later leakage, and can greatly enhance the compressive strength of the siphon drainage trough body.
[0047] Optionally, in order to improve the overlapping effect between the overlapping part 22 and the drainage plate 3, the protruding length of the overlapping part 22 in the transverse direction is greater than or equal to 80 mm. Preferably, the protruding 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.
[0048] Optionally, as Figure 1 and Figure 2 shown, a plurality of drainage ports 12 communicating with the drainage cavity 11 and arranged at intervals longitudinally are provided on the lateral part of the drainage trough body 1 in the transverse direction.
[0049] Optionally, the drainage trough bottom plate 2 and the drainage trough body 1 can form a detachable connection. For example, the drainage trough body 1 and the drainage trough bottom plate 2 are set as snap - connections, making the installation and transportation of the drainage trough more convenient. Or, the drainage trough body 1 and the drainage trough bottom plate 2 can also be adhesively connected, etc.
[0050] In some specific embodiments, as Figure 1 and Figure 2As shown, the drain trough body 1 may include a cavity wall portion 13 and two first buckle portions 14. The cavity wall portion 13 is arched and defines a drain cavity 11. The opening of the drain cavity 11 faces downward. The two first buckle portions 14 correspondingly extend outward transversely from two bottom ends of the cavity wall portion 13 that are opposite to each other transversely. The inner end of the overlapping portion 22 in the transverse direction is provided with a second buckle portion 25 that is buckled and cooperated with the first buckle portion 14. The drain trough body 1 is fixedly installed on the drain trough bottom plate 2 through the buckling cooperation between the first buckle portion 14 and the second buckle portion 25.
[0051] Among them, the buckling cooperation structure between the first buckle portion 14 and the second buckle portion 25 can be various. One of the first buckle portion 14 and the second buckle portion 25 can be formed into a tongue, and the other is formed into a groove. In order to simplify the structure of the drain trough and reduce the manufacturing cost, as Figure 1 and Figure 2 shown, the first buckle portion 14 can be formed into a flat tongue extending transversely, and the second buckle portion 25 can be formed into a groove opening inward.
[0052] Optionally, in order to take into account the structural strength and manufacturing cost of the drain trough bottom plate 2, as Figure 1 and Figure 2 shown, the thickness of the overlapping portion 22 gradually decreases outward transversely, that is, the thickness of the inner end of the overlapping portion 22 in the transverse direction is greater than the thickness of the outer end in the transverse direction, and the thickness of the inner end of the overlapping portion 22 in the transverse direction is greater than the thickness of the cover portion 21. Among them, the minimum thickness of the drain trough bottom plate 2 can be greater than 0.5 mm and less than or equal to 2 mm. Preferably, the minimum thickness of the drain trough bottom plate 2 is 1 mm. As Figure 1 and Figure 2 shown, the cover portion 21 is a flat plate with an average thickness. The thickness of the cover portion 21 can be 1 mm, while the thickness of the overlapping portion 22 gradually decreases outward transversely. The thickness of the inner end of the overlapping portion 22 in the transverse direction can be greater than 1.5 mm. Preferably, the thickness of the inner end of the overlapping portion 22 in the transverse direction can be 5 mm, and the thickness of the outer end of the overlapping portion 22 in the transverse direction can be 1 mm.
[0053] In addition, as Figure 4 and Figure 5 shown, the inner end of the overlapping portion 22 in the transverse direction can be provided with a plurality of second buckle portions 25 longitudinally. The longitudinal spacing between any two adjacent second buckle portions 25 can be greater than or equal to 250 mm and less than 300 mm. Preferably, the longitudinal spacing between any two adjacent second buckle portions 25 can be set to 280 mm. For example, the second buckle portion 25 can be formed into a groove with a longitudinal length of 20 mm, a transverse length of 8 mm, and a longitudinal height of 2 mm.
[0054] In some specific embodiments, plug-in structures capable of plugging and mating are formed at both longitudinal ends of the drainage trough body 1. To further improve the root penetration resistance of the drainage structure, as Figure 4 and Figure 5 shown, at one longitudinal end of the drainage trough body 1 and the drainage trough bottom plate 2, the drainage trough body 1 extends longitudinally outward to form a plug-in end portion, and the overlapping portion 22 extends longitudinally outward and is arranged at intervals transversely with the plug-in end portion; at the other longitudinal end of the drainage trough body 1 and the drainage trough bottom plate 2, the drainage trough bottom plate 2 extends longitudinally outward and extends to the longitudinal outside of the drainage trough body 1, so that the drainage trough bottom plates 2 can overlap each other longitudinally when two drainage troughs are plugged and connected. Among them, when two drainage troughs are plugged and connected, the opposite end portions of the two drainage trough bottom plates 2 overlap each other longitudinally and can be connected by welding or bonding.
[0055] In some specific embodiments, to greatly improve the construction efficiency of the drainage structure, an adhesive layer 23 is provided on the bottom surface of the drainage trough bottom plate 2. The treatment of the overall rubber coating on the bottom surface of the drainage trough bottom plate 2 can improve the construction convenience, construction efficiency and ensure the construction quality compared with the traditional method of fixing the drainage trough with an adhesive tape.
[0056] Optionally, in order to protect the adhesive layer 23, an isolation film 24 can be provided on the outside of the adhesive layer 23. When installing the drainage trough on the roof or the basement top slab, the construction personnel then tear off the isolation film 24.
[0057] The third aspect of the present application also provides a drainage structure, as Figure 3 shown, the drainage structure includes a drainage board 3 and the above-mentioned drainage trough, and the edge portion 31 of the drainage board 3 is welded and overlapped or adhesively overlapped with the overlapping portion 22. In this way, an integrated and complete drainage channel can be formed for the drainage trough, increasing the service life of the drainage channel, ensuring the drainage effect of the drainage channel, effectively preventing plant roots from penetrating and damaging 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 trough, it also has all the technical effects brought by the above-mentioned drainage trough, so it will not be repeated here.
[0058] In some specific embodiments, as Figure 3 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, and the drainage structure further includes a drainage mesh pad 4, and the drainage mesh pad 4 is arranged between the drainage diversion portion 32 and the drainage trough body 1 and above the edge portion 31 of the drainage board 3. In this way, the drainage mesh pad 4 is arranged at the overlapping position between the drainage board 3 and the overlapping portion 22, and the drainage mesh pad 4 can be used as a connecting gasket to ensure the smoothness of the drainage channel.
[0059] Optionally, as Figure 3As shown in the figure, a drainage board geotextile 33 is provided on the top surface of the drainage and diversion part 32 of the drainage board 3. The drainage structure further includes a drainage groove geotextile 5, which is laid above the drainage groove and overlaps with the drainage board geotextile 33. The drainage net pad 4 is located below the overlapping section between the drainage board geotextile 33 and the drainage groove geotextile 5. In this way, a structurally complete and reasonable drainage structure can be formed, which has good drainage and waterproof effects and a long service life.
[0060] In summary, the present application provides a drainage trough bottom plate, a drainage trough and a drainage structure. The drainage trough and the drainage structure have a bottom plate, and have good drainage and waterproof effects; the bottom plate is provided with a self-lapping part that can be welded to the large-area drainage board, which can play a role in root penetration resistance, and the structure of the bottom plate with rubber coating can greatly improve the construction efficiency of the drainage trough.
