Description

Sump and sump assembly

Technical Field

The invention relates to the technical field of green buildings, in particular to a water collecting tank and a water collecting tank assembly, which are used for a siphon drainage system of a planting top plate of an underground garage.

Background

The water collecting tank is mainly used for collecting penetrating water from planting soil on a roof plate of a planting roof, and the penetrating water flows to the drainage plate after being filtered by geotextile. The structure of the water collecting opening on the existing water collecting tank can not effectively reduce the resistance of penetrating water entering the water collecting tank, and the converging time is long, so that the penetrating water can not be rapidly discharged under the condition of heavy storm.

Furthermore, the sump is subjected to significant stresses from the planting soil layer during use, so that in addition to reinforcing it in terms of sump material selection, it is also necessary to design a suitable sump structure to structurally reinforce it.

Finally, in order to facilitate field assembly, the connection between the water collection tanks and between other components should be easy and reliable, and the existing connection means should be further improved.

Exemplary embodiments of the water collection sump 1 and the water collection sump assembly 2 of the present invention are described next in connection with fig. 1a to 7 b. The water collection tank 1 and the water collection tank assembly 2 can be used as a component of a siphon drainage system of a planting roof of an underground garage.

Fig. 1a to 1i show a water collection sump 1 according to a first embodiment of the invention. The water collection sump 1 may have an elongated structure and may have a substantially arched cross section. The water collection sump 1 may have a main body section 3 located in the middle and connecting

sections

4, 5 located at both ends of the main body section 3, seen in the longitudinal direction of the water collection sump 1. The water collection trough 1 can have a centrally located curvature section 6 and hemmed sections 7 located on both sides of the curvature section 6, seen in the transverse direction of the water collection trough 1. The hemming section 7 may extend over the entire body section 3 and the connecting

sections

4, 5 and may adjoin the lateral edges of the arching section 6.

The arched section 6 of the water collection trough 1 may have a longitudinal reinforcement. The longitudinal reinforcement may have a plurality of ridges 8 extending straight parallel to the longitudinal axis of the sump 1. The ridge 8 may have a substantially arc-shaped cross section and its arc top may be directed towards the outside of the sump 1. The ridge 8 may extend over the entire length of the sump 1 and have a substantially uniform cross section. Between every two ridge portions 8 can be connected by a valley portion 9. The valley 9 may have a substantially arc-shaped cross section and its arc top is directed towards the inside of the sump 1. The valley portions 9 as transition portions between adjacent ridge portions 8 may make the transition between adjacent ridge portions 8 smooth. The valley 9 may extend over the entire length of the sump 1 and may have a substantially uniform cross section. The cross-sectional dimension of the valley 9 may be smaller than the cross-sectional dimension of the ridge 8.

The ridges 8 and valleys 9 of the longitudinal reinforcement may be arranged successively in the entire lateral direction of the arched section 6 of the water collection trough 1. It is of course also conceivable that only a partially arched section 6 of the water collection trough 1 can be formed by a ridge 8 and a valley 9. The successive arrangement of ridges 8 and valleys 9 of the longitudinal reinforcement structure may be such that the longitudinal reinforcement structure is at least partly in a folded-over configuration. The arched section 6 of the water collection trough 1 can therefore have a wavy cross section in its transverse direction, which can be seen more clearly from the partial cross section view 1g of the arched section 6 with the longitudinal reinforcement in the straight-line unfolded state. In this case, the curvature section 6 of the water collection trough 1 can have a substantially uniform thickness over its entire transverse direction, even in the presence of a longitudinal reinforcement, but this is not a mandatory requirement.

In some embodiments, ridges 8 and valleys 9 may additionally be provided successively on the otherwise smooth outer and/or inner surface of the arched section 6 of the water collection trough 1, so that the ridges 8 and valleys 9 of the longitudinal reinforcement may form a surface reinforcement on the surface of the arched section 6. The surface reinforcement on the outer surface of the camber section 6 may thus be independent of the surface reinforcement on the inner surface of the camber section 6 in terms of the arrangement position, size, arrangement density, arrangement extent, etc. of the ridges 8 and valleys 9. The curvature section 6 can have a non-uniform thickness due to the presence of the surface reinforcement. It is of course also conceivable that the folded-over structure of ridges 8 and valleys 9 and the surface reinforcement structure described above can be provided at the same time on the arched section 6.

Referring to fig. 1d, the inside of the top of the sump 1 may be smooth, i.e. no longitudinal reinforcement is provided, whereas the outside of the top is provided with a longitudinal reinforcement. Since the sump 1 is integrally injection-molded by a mold having a corresponding structure, the above structure of the sump 1 can be achieved by presetting the inner structure of the mold.

The longitudinal reinforcement of the water collection sump 1 may reinforce the arched section 6 of the water collection sump 1 in the longitudinal direction as well as in a lateral direction to some extent. The provision of ridges 8 and valleys 9 not only allows the sump 1 to have more material in the transverse direction, which is beneficial for the strength reinforcement of the sump 1, but also the structural form constituted by the ridges 8 and valleys 9 is beneficial for the further strength reinforcement, thereby greatly improving the pressure resistance of the arch section 6 and preventing the arch section 6 from being dented or crushed in its part.

The arched section 6 of the water collection trough 1 may have a transverse reinforcement structure, which may have a plurality of (in this exemplary embodiment three) reinforcement strands 10 extending transversely, for example perpendicularly, to the longitudinal axis of the water collection trough 1 and transversely of the arched section 6 following the arched section 6 in a curved manner. The reinforcement strand 10 may have a substantially arc-shaped cross section with its arc-tip directed towards the inside of the water collection sump 1, see fig. 1h. In other words, the reinforcement strand 10 can be formed from the material of the arch section 6 in an inwardly concave manner. The wall thickness of the reinforcement strand 10 may be the same as the wall thickness of the rest of the arch section 6, but this is not mandatory, for example a thicker wall thickness may be provided to increase the reinforcement effect. Thus, the reinforcement strand 10 can form an inward depression as seen from the outside of the arch section 6 (see fig. 2 a), and an inward bulge as seen from the inside of the arch section 6 (see fig. 2 b). The reinforcement strand 10 can extend over the entire transverse direction (or if appropriate only part of the transverse direction) of the arched section 6 of the water collection trough 1 and can have a uniform cross section. The plurality of reinforcement strands 10 of the transverse reinforcement structure may be arranged one after the other at a distance (for example 100mm-200mm, for example 150 mm) apart in the longitudinal direction of the arched section 6 of the water collection trough 1.

The transverse reinforcement of the water collection sump 1 may reinforce the arched section 6 of the water collection sump 1 in the transverse direction. The provision of the reinforcement strands 10 not only makes it possible for the water collection sump 1 to have more material in the longitudinal direction, which is advantageous for the strength reinforcement of the water collection sump 1, but also the structural form constituted by the reinforcement strands 10 themselves is advantageous for the further strength reinforcement. Vertical forces from the planting layer, which may exert a lateral component, are applied to the arch of the arch section 6. The transverse reinforcement structure or reinforcement strands 10 can effectively resist these transverse force components, thereby preventing lateral displacement or even lateral collapse of the material of the arch section 6.

The arched section 6 of the water collection trough 1 may be provided with a plurality of generally square or arched or other suitably shaped indentations in its lateral (in this embodiment on both sides) lower part, which indentations may open downwards and to both sides. The hemming section 7 may abut the edge of the cutout outside the cutout and thus enclose the cutout. The notch may form a water collecting opening 11 according to the invention together with the hem section 7 surrounding the notch. The water filtered by the geotextile and flowing onto the drain plate can be converged into the water collecting tank 1 via the water collecting port 11. A plurality of water collection openings 11 may be arranged one after the other in the longitudinal direction of the arch section 6. In the present embodiment, one water collection port 11, i.e. four water collection ports 11 per side, may be provided between each two reinforcement strands 10 and between the reinforcement strands 10 and the

connection sections

4, 5, respectively. It is of course also conceivable to provide a greater or lesser number of water collection openings 11. The water collection openings 11 on both sides of the arch section 6 can be arranged opposite one another in pairs or offset from one another.

As can be seen from fig. 1a to 1f, in particular fig. 1i, the water collection opening 11 has a bell mouth structure, i.e. the cross-sectional dimension of the water collection opening 11 can be gradually reduced or tapered from the outer edge of its folded-over section 7 to the arched section 6. The outer edge of the water collection port 11 may be sized with respect to the structure of the drain plate to achieve sufficient water inflow efficiency.

The tapered flare structure of the water collection port 11 can facilitate water on the drain plate to flow into the water collection tank 1 via the water collection port 11.

Since the water collection sump 1 in this embodiment may have water collection openings 11 on both sides thereof, the water collection sump 1 may be adapted to be arranged in the middle of the drain plate so that the water collection sump 1 may collect water on the drain plate on both sides thereof.

The connecting

sections

4, 5 of the water collection sump 1 can be of two types, which two types of connecting sections 4, 5 (hereinafter "first connecting section 4" and "second connecting section 5") can be complementary to one another and can be connected to one another in a form-fitting manner.

The first connecting section 4 is visible from the left in fig. 1a, 1c to 1e and from the right in fig. 1 b. The first connecting section 4 may comprise a central arching section 6 and hemmed sections 7 on both sides of the arching section 6. The first connection section 4 may have a reduced wall thickness, for example reduced by half, relative to the body section 3, and the inner side of the first connection section 4 may be flush with the inner side of the body section 3, while the outer side of the first connection section 4 may be recessed relative to the outer side of the body section 3, such that the outer side of the first connection section 4 may form a reduced smooth step surface relative to the outer side of the body section 3, which may form the first mating surface 12 of the first connection section 4. The arched section 6 of the first connecting section 4 may have a hole, for example a through hole 13 (blind holes are also conceivable), at its top for connection. The through holes 13 may have a cylindrical shape in this embodiment and have a number of 2. Other shapes or numbers of through holes 13 are of course also conceivable. Likewise, the folded-over sections 7 on both sides of the first connecting section 4 can each have a hole for connection, for example a through hole 13.

The second connecting section 5 is visible from the left in fig. 1b and from the right in fig. 1 d. The second connecting section 5 may comprise a central arching section 6 and hemmed sections 7 on both sides of the arching section 6. The second connection section 5 may have a reduced wall thickness, for example reduced by half, relative to the body section 3, and the outer side of the second connection section 5 may be flush with the outer side of the body section 3, while the inner side of the second connection section 5 may be recessed relative to the inner side of the body section 3, such that the inner side of the second connection section 5 may form a reduced smooth step surface relative to the inner side of the body section 3, which may form the second mating surface 14 of the second connection section 5. The second mating surface 14 of the second connecting section 5 can form-fit with the first mating surface 12 of the second connecting section 5. The arched section 6 of the second connection section 5 may be attached on its top inner side with an inwardly extending protrusion 15 for connection. In this embodiment, the projections 15 on the arched section 6 of the second connection section 5 can have a cylindrical shape and be 2 in number, in cooperation with the through-holes 13 on the arched section 6 of the first connection section 4. The length of the projection 15 on the arched section 6 of the second connection section 5 may be equal to, smaller than or larger than (in the present embodiment equal to) the depth of the through hole 13. Furthermore, the folded-over sections 7 on both sides of the second connecting section 5 can each have a projection 15. The length of the projection 15 on the hem section 7 of the second connection section 5 may be equal to or less than the depth of the through hole 13 on the hem section 7 of the first connection section 4.

For example, referring to fig. 1a and 1b, the first connecting section 4 and the second connecting section 5 may have the above-described longitudinal reinforcing section or the longitudinal reinforcing section may also extend thereon.

The first connection section 4 and the second connection section 5 provided on different water collection tanks 1 can be connected to each other in a form-locking manner. When two water collection tanks 1 are to be connected to one another, only the first connection section 4 on one water collection tank 1 and the second connection section 5 on the other water collection tank 1 need to be connected to one another in a form-fitting manner, wherein the first mating surface 12 and the second mating surface 14 can overlap one another or can be form-fitted, and the projections 15 can be inserted into the through holes 13 in a form-fitting manner, so that a mortise-tenon joint is formed. The sum of the thicknesses of the first connection section 4 and the second connection section 5 may be equal to the thickness of the body section 3 of the water collection tank 1, so that after connection the transition between the body sections 3 of the respective water collection tank 1 is smooth.

The present invention is not limited to the embodiment in which the first and second connection sections 5 are provided differently at both ends of the sump 1, respectively. It is also possible to provide two identical first connecting sections 4 or two identical second connecting sections 5 at both ends of the water collection sump 1. As long as the two water collection tanks 1 to be connected each have a different first connection section 4 and a second connection section 5 which can be connected to each other.

Fig. 2a to 2c show a water collection sump 1 according to a second embodiment of the invention. Unlike the water collection sump 1 of the first embodiment, the water collection sump 1 of the second embodiment may have the water collection port 11 only on one side thereof, and no water collection port 11 on the other side of the water collection sump 1. The hem section 7 on the other side can thus extend straight over the entire length of the water collection sump 1. Since the water collection sump 1 in this embodiment has the water collection opening 11 only on one side thereof, the water collection sump 1 may be adapted to be arranged around the drain plate with its water collection opening 11 facing the drain plate, so that the water collection sump 1 may collect water on the drain plate only on one side thereof.

As to other features of the water collection sump 1 of the second embodiment, reference may be made to the description of the water collection sump 1 of the first embodiment.

Fig. 3a to 3e show one embodiment of the four-way joint 16 of the present invention. The four-way connector 16 may have a generally cross-shaped configuration in top view. The four-way connection 16 can have a tube connection 17 at the center top for connecting a ventilation viewing tube (not shown) and two pairs of 4 opposite connections 18. The tube interface 17 may have a cylindrical shape (this embodiment) or other polygonal shape. The four joints 18 may intersect each other, and the pipe interface 17 may be located at the intersection of the four joints 18.

The cross-sectional configuration of the joint 18 may correspond to the cross-sectional configuration of a component to be connected thereto, such as the sump 1. Each joint 18 may have at its free end the above-mentioned first connection section 4 or second connection section 5 of the water collection sump 1 for connection with the water collection sump 1 or with water stops 19, 20 which are further described below. In the illustrated embodiment, each pair of opposing joints 18 has a first connection section 4 and a second connection section 5, respectively, but this is not mandatory as long as the component to be connected with the joint 18 has a

corresponding connection section

4, 5 that is different from the joint 18.

As can be seen in the figures, each joint 18 may have a longitudinal reinforcement of the sump 1 to strengthen the joint 18.

Fig. 4a and 4b show a water deflector 19 without holes, which water deflector 19 may have the above-described first connection section 4 of the water collection sump 1 and a planar baffle 21 connected thereto at one end of the first connection section 4. The planar baffle 21 may have no holes and may cover the end of the first connecting section 4 completely closed. The water deflector 19 can be connected via its first connecting section 4 to the joint 18 of the four-way joint 16 with the second connecting section 5, so that the planar baffle 21 of the water deflector can completely close the joint 18 so that water cannot flow out of the joint 18. It is of course also conceivable for the water deflector 19 to have a second connecting section 5.

Fig. 5a and 5b show a perforated water deflector 20, which water deflector 20 may have the above-mentioned first connection section 4 of the water collection trough 1, a perforated planar baffle 21 connected thereto at one end of the first connection section 4, and a cylindrical drainage connection 22 surrounding the hole and extending away from the planar baffle 21. The drain interface 22 may also have other suitable shapes. The drain connection 22 and the first connecting section 4 can be injection molded in one piece. The water deflector 20 can be connected via its first connection section 4 to the joint 18 of the four-way joint 16 with the second connection section 5, so that water flowing from the water collection sump 1 into the joint 18 is discharged via the drain connection 22. The drain interface 22 may be further connected with its free end to a siphon tube (not shown) for draining water via the siphon tube (not shown). It is of course also conceivable for the water deflector 20 to have a second connection section 5.

Fig. 6a and 6b show a sump assembly 2 according to a first embodiment of the invention. The sump assembly 2 may comprise a sump 1 according to the first embodiment, which has a water collecting opening 11 at both sides, a four-way joint 16 connected to the sump 1 by means of

connection sections

4, 5, an un-perforated water deflector 19 connected to one joint 18 of the four-way joint 16, and a perforated water deflector 20 connected to the other joint 18 of the four-way joint 16. The perforated water deflector 20 may be arranged opposite the water collection sump 1. The four-way connection 16 can also have a free connection 18, which connection 18 can be used to connect another water collection sump 1 or

water deflector

19, 20. The sump assembly 2 may be arranged in the middle of the drain plate based on the water collecting ports 11 at both sides thereof.

Fig. 7a and 7b show a sump assembly 2 according to a second embodiment of the invention. The sump assembly 2 may comprise a sump 1 according to the second embodiment, which has a water collecting opening 11 at only one side, a four-way joint 16 connected to the sump 1 by means of

connection sections

water deflector

19, 20. The sump assembly 2 may be arranged around the drain plate based on its water collection port 11 on only one side and with its water collection port 11 side facing the drain plate.

The water collection tank 1 and the water collection tank assembly 2 for the top plate siphon drainage system for the underground garage have the advantages of: first, the lateral compressive resistance of the water collection sump 1 is improved by the lateral stiffening with the stiffening strands 10. The transverse reinforcement structure or reinforcement strands 10 are effective against transverse force components, thereby preventing lateral displacement or even lateral collapse of the material of the arch section 6; the longitudinal reinforcement of the second, water collection sump 1, which is formed by the ridges 8 and valleys 9, results in an increased pressure resistance of the water collection sump 1. The longitudinal reinforcement structure can strengthen the arch section 6 of the water collecting tank 1 longitudinally and transversely to some extent, thereby improving the compression resistance of the arch section 6 and preventing the arch section 6 from being dented or crushed at partial parts thereof; thirdly, the water collection port 11 of the water collection tank 1 is adapted to the structure of the drain plate, for example, the height thereof, by the accurate setting of the position and the size of the water collection port 11. In addition, the water collecting port 11 adopts a horn-shaped design, and the water collecting port is large in outside and small in inside, so that the resistance of water entering the water collecting tank 1 is reduced, the converging time is shortened, and the water on the water draining plate is converged into the water collecting tank 1 more quickly, thereby effectively controlling the water level of the top plate of the underground garage under the condition of heavy storm; and the fourth water collecting tank component and the water collecting tank component are connected in a form-locking connection and a mortise-tenon connection mode, so that the water collecting tank component is more convenient to detach and install and is convenient for site construction. The design of the mating surfaces is such that the connected water collection sump 1 or water collection sump assembly 2 has a smooth transition on its outer and inner sides.
