It should be noted here that numerous modifications and changes can be carried out with respect to the forms and details of the embodiments without departing from the general idea of the invention.

Next, an exemplary embodiment of the sump 1 and the sump assembly 2 of the present invention will be described with reference to FIGS. 1a to 7b. The sump 1 and the sump assembly 2 can be used as components of the planted roof siphon drainage system of the underground garage.

Figures 1a to 1i show a sump 1 according to a first embodiment of the invention. The sump 1 may have an elongated configuration and may have an approximately arcuate cross-section. Seen in the longitudinal direction of the sump 1 , the sump 1 can have a central body section 3 and connecting

sections

4 , 5 at both ends of the body section 3 . Seen in the transverse direction of the sump 1 , the sump 1 can have a centrally located arched section 6 and flanged sections 7 on both sides of the arched section 6 . The flange section 7 can extend over the entire body section 3 and the connecting

section

4 , 5 and can adjoin the lateral edges of the curved section 6 .

The curved section 6 of the sump 1 can have a longitudinal reinforcement. The longitudinal reinforcing structure may have a plurality of ridges 8 extending linearly parallel to the longitudinal axis of the sump 1 . The convex ridge 8 may have a substantially arc-shaped cross section and its arc top may face outside the sump 1 . The raised ridge 8 may extend over the entire length of the sump 1 and have a substantially uniform cross-section. Every two ridges 8 can be connected by a valley 9 . The valley portion 9 may have a substantially arc-shaped cross-section and its arc top faces toward the inside of the sump 1 . The valley portion 9 as a transition portion between adjacent ridge portions 8 can make the transition between adjacent ridge portions 8 smooth. The valleys 9 can extend over the entire length of the sump 1 and have essentially a uniform cross section. The cross-sectional dimension of the valley portion 9 may be smaller than the cross-sectional dimension of the ridge portion 8 .

The ridges 8 and the valleys 9 of the longitudinal reinforcement can be arranged one behind the other across the entire transverse direction of the curved section 6 of the sump 1 . It is of course also conceivable that only partially curved sections 6 of the sump 1 can be formed by ridges 8 and valleys 9 . The successive arrangement of ridges 8 and valleys 9 of the longitudinal reinforcement makes it possible for the longitudinal reinforcement to be at least partially in the form of a flap. Therefore, the arched section 6 of the sump 1 can have a wave-shaped cross-section in its transverse direction, which can be seen more clearly from the partial cross-sectional view 1g of the arched section 6 with a longitudinal reinforcement structure in a straight-line unfolded state . Here, even with the presence of the longitudinal reinforcement, the arched section 6 of the sump 1 can have a substantially uniform thickness over its entire transverse direction, but this is not strictly required.

In some embodiments, the originally smooth outer surface and/or inner surface of the arched section 6 of the sump 1 may additionally be provided with ridges 8 and valleys 9 in succession, so as to longitudinally strengthen the structure. The ridges 8 and the valleys 9 can form surface reinforcements on the surface of the curved section 6 . The surface reinforcement structure on the outer surface of the arched section 6 can therefore be independent from the inner surface of the arched section 6 in terms of the arrangement position, size, arrangement density, arrangement range, etc. of the ridges 8 and valleys 9 Surface reinforced structure. In this case, the curved section 6 can have a non-uniform thickness due to the presence of the surface reinforcement. Of course, it is also conceivable that the above-mentioned folded plate structure and surface reinforcement structure formed by the ridges 8 and the valleys 9 can be provided on the curved section 6 at the same time.

Referring to Fig. 1d, the inside of the top of the sump 1 may be smooth, that is, no longitudinal reinforcement structure is provided, and a longitudinal reinforcement structure is provided on the outside of the top. Since the sump 1 is integrally molded by a mold having a corresponding structure, the above structure of the sump 1 can be realized by presetting the internal structure of the mould.

The longitudinal reinforcement of the sump 1 can reinforce the curved section 6 of the sump 1 longitudinally and to some extent transversely. The arrangement of the ridges 8 and the valleys 9 not only enables the sump 1 to have more material in the lateral direction, which is beneficial to strengthening the strength of the sump 1, but also the structure formed by the ridges 8 and the valleys 9 The structural type is also beneficial to the further strengthening of the strength, thereby greatly improving the compressive capacity of the arched section 6 and preventing the arched section 6 from being dented or broken locally.

The arched section 6 of the sump 1 can have a transverse stiffening structure, which can have several (three in this embodiment) transverse, for example perpendicular to, the longitudinal axis of the sump 1 and at the curvature. The segment 6 follows the arcuately extending reinforcing strand 10 transversely in the direction of the arched segment 6 . The reinforcing strand 10 may have a substantially arc-shaped cross section with the top of the arc facing the inside of the sump 1 , see FIG. 1h . In other words, the reinforcing strand 10 can be formed by the material of the curved section 6 being recessed inwardly. The wall thickness of the reinforcement strand 10 can be the same as that of the rest of the arched section 6, but this is not mandatory, for example it can have a thicker wall thickness to increase the reinforcement effect. The reinforcing strand 10 can thus form an inward depression viewed from the outside of the arched section 6 (see FIG. 2 a ) and an inward protrusion viewed from the inside of the arched section 6 (see FIG. 2 b ). The reinforcing strand 10 can extend over the entire transverse direction (or possibly only partly) of the curved section 6 of the sump 1 and have a uniform cross section. A plurality of reinforcing strands 10 of the transverse reinforcing structure can be arranged successively at a distance (for example 100 mm-200 mm, for example 150 mm) in the longitudinal direction of the arched section 6 of the sump 1 .

The transverse reinforcement of the sump 1 can reinforce the curved section 6 of the sump 1 in the transverse direction. The arrangement of the reinforcing strands 10 not only enables the sump 1 to have more material in the longitudinal direction, which is beneficial to strengthening the strength of the sump 1, but also the structural pattern formed by the reinforcing strands 10 itself is beneficial to further strengthening the strength. Vertical forces from the planting soil layer that act on the vault of the arched section 6 generate transverse force components. The transverse reinforcing structure or reinforcing strand 10 can effectively resist these transverse component forces, thereby preventing the material of the arched section 6 from lateral displacement or even lateral collapse.

The arched section 6 of the sump 1 can be provided with a plurality of substantially square or arched or other suitable shaped notches at its lateral (both sides in this embodiment) lower part, and the notches can be downward and to both sides. side open. The flange section 7 can adjoin the edge of the opening on the outside of the opening and thus surround the opening. Together with the flange section 7 surrounding the cutout, the cutout can form the water collecting opening 11 according to the invention. The water flowing onto the drainage plate after being filtered by the civil cloth can be converged to the inside of the sump 1 through the water collection port 11 . A plurality of water collecting openings 11 can be arranged one behind the other in the longitudinal direction of the curved section 6 . In this embodiment, one water collection port 11 can be provided between every two reinforcement strands 10 and between the reinforcement strands 10 and the connecting

sections

4 , 5 , that is, four water collection ports 11 on each side. 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 arched section 6 can be arranged in pairs facing each other, or can be arranged staggered from each other.

From Figures 1a to 1f, especially Figure 1i, it can be seen that the water collecting port 11 has a bell mouth structure, that is to say, the cross-sectional dimension of the water collecting port 11 can be extended from the outer edge of the flanged section 7 to the arched section 6 Gradually decrease or taper. The size of the outer edge of the water collecting port 11 can be set in relation to the structure of the drain plate so as to obtain sufficient water inflow efficiency.

The tapered bell mouth structure of the water collecting port 11 can facilitate the water on the drain plate to flow into the water collecting tank 1 through the water collecting port 11 .

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

The

connection sections

4, 5 of the sump 1 can be of two types, and these two types of connection sections 4, 5 (hereinafter referred to as "first connection section 4" and "second connection section 5") can be connected to each other. Complementary and form-fittingly connectable to each other.

The first connection section 4 can be seen from FIGS. 1 a , 1 c to 1 e to the left and FIG. 1 b to the right. The first connecting section 4 may include an arched section 6 in the middle and hemming sections 7 on both sides of the arched section 6 . The first connecting section 4 may have a reduced wall thickness relative to the main body section 3 , for example reduced by half, and the inner side of the first connecting section 4 may be flush with the inner side of the main body section 3 , while the first The outer surface of the connecting section 4 can be recessed relative to the outer surface of the main body section 3, so that the outer surface of the first connecting section 4 can form a lowered smooth step surface with respect to the outer surface of the main body section 3, and the stepped surface A first mating surface 12 of the first connection section 4 can be formed. The curved section 6 of the first connecting section 4 can have a connection hole at its top, for example a through hole 13 (blind holes are also conceivable). The through holes 13 may have a cylindrical shape and be two in number in this embodiment. Of course, other shapes or numbers of through openings 13 are also conceivable. Likewise, the flanged sections 7 on both sides of the first connecting section 4 can each have holes for connection, for example through-holes 13 .

The second connection section 5 can be seen from the left in FIG. 1b and from the right in FIG. 1d. The second connection section 5 may include an arched section 6 in the middle and hemming sections 7 on both sides of the arched section 6. The second connection section 5 may have a reduced wall thickness relative to the main body section 3, for example, reduced by half, and the outer side of the second connection section 5 may be flush with the outer side of the main body section 3, while the second The inner surface of the connection section 5 can be recessed relative to the inner surface of the main body section 3, so that the inner surface of the second connection section 5 can form a lowered smooth step surface with respect to the inner surface of the main body section 3, and the stepped surface A second mating surface 14 of the second connection section 5 can be formed. The second mating surface 14 of the second connecting section 5 can form a 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 at its top inner side with an inwardly extending protrusion 15 for connection. In this embodiment, the protrusion 15 on the arcuate section 6 of the second connection section 5 may have a cylindrical shape in cooperation with the through hole 13 on the arcuate section 6 of the first connection section 4 , and the number is 2. The length of the protrusion 15 on the arcuate section 6 of the second connection section 5 may be equal to, smaller than, or larger than (in this embodiment, equal to) the depth of the through hole 13 . Furthermore, the flange sections 7 on both sides of the second connecting section 5 can each have a protrusion 15 . The length of the protrusion 15 on the hem section 7 of the second connection section 5 may be equal to or smaller than the depth of the through hole 13 on the hem section 7 of the first connection section 4 .

For example, referring to FIGS. 1 a and 1 b , the first connection section 4 and the second connection section 5 can have the above-mentioned longitudinal reinforcement section, or the longitudinal reinforcement section can also extend thereon.

The first connection section 4 and the second connection section 5 arranged on different sumps 1 can be connected to each other in a positive fit. When two sumps 1 need to be connected to each other, only the first connection section 4 on one sump 1 and the second connection section 5 on the other sump 1 are form-fittingly connected to each other, wherein, The first mating surface 12 and the second mating surface 14 can overlap each other or fit in shape, and the protrusion 15 can be inserted into the through hole 13 in a form-fitting manner, thereby forming a mortise and tenon connection. 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 sump 1, so that after connection the transition between the body sections 3 of the sump 1 is smooth of.

The present invention is not limited to the different first and second connecting sections 5 provided at both ends of the sump 1 in this embodiment. Two identical first connecting sections 4 or two identical second connecting sections 5 may also be provided at both ends of the sump 1 . As long as the two water collection tanks 1 to be connected respectively have different first connecting sections 4 and second connecting sections 5 that can be connected to each other.

2a to 2c show a sump 1 according to a second embodiment of the invention. Unlike the sump 1 of the first embodiment, the sump 1 of the second embodiment may have the sump 11 only on one side thereof without the sump 11 on the other side of the sump 1 . The flange section 7 on this other side can therefore extend linearly over the entire length of the sump 1 . Since the sump 1 in this embodiment only has a water collection opening 11 on one side thereof, the sump 1 can be adapted to be arranged around the drainage plate and face the drainage plate with its water collection opening 11, so that the sump 1 can only be placed on its side. One side collects water on the drain plate.

Regarding other features of the sump 1 of the second embodiment, reference may be made to the relevant description of the sump 1 of the first embodiment.

Figures 3a to 3e show an embodiment of the cross joint 16 of the present invention. The cross joint 16 may have a generally cruciform configuration in plan view. The four-way joint 16 may have a pipe joint 17 on the central top for connecting a gas-permeable observation tube (not shown) and two pairs of four joints 18 opposite to each other. The pipe connection 17 may have a cylindrical shape (in the present embodiment) or another 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 structure of the connection 18 can correspond to the cross-sectional structure of the component to be connected thereto, such as the sump 1 . Each joint 18 can have at its free end the above-mentioned first connection section 4 or the second connection section 5 of the sump 1, for connecting with the sump 1 or with the water retaining member 19, which will be explained below, 20 connections. 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 parts to be connected to the joint 18 have a connection with the joint. 18 different

corresponding connection sections

4 and 5 are sufficient.

As can be seen from the figure, each joint 18 may have a longitudinal reinforcing structure of the sump 1 to strengthen the joint 18 .

Figures 4a and 4b show a water stop 19 without holes, which may have the above-mentioned first connection section 4 of the sump 1 and a planar stop connected thereto at one end of the first connection section 4. plate 21. The flat cover 21 can have no holes and can cover the end of the first connection section 4 completely closed. The water stop 19 can be connected via its first connection section 4 to the joint 18 of the cross joint 16 with the second connection section 5, so that the planar baffle 21 of the water stop can completely close the joint 18, so that Water cannot flow out of this connection 18 . It is of course also conceivable that the water stop 19 can have a second connection section 5 .

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

Figures 6a and 6b show a sump assembly 2 according to the invention according to a first embodiment. The sump assembly 2 may comprise a sump 1 according to the first embodiment (which has a sump 11 on both sides), a cross joint 16 connected to the sump 1 via connecting

sections

4, 5, a cross joint 16 connected to the cross joint. A non-perforated water stop 19 of one joint 18 of 16, and a perforated water stop 20 connected to the other joint 18 of the cross joint 16. The perforated water retaining member 20 can be arranged opposite to the sump 1. The four-way connection 16 can also have a free connection 18 which can be used to connect another sump 1 or a

water stop

The water retaining member 20 with holes can be arranged opposite to the sump 1 . The four-way connection 16 can also have a free connection 18 which can be used to connect another sump 1 or a

water stop

19 , 20 . Due to its water collecting opening 11 on only one side, the sump assembly 2 can be arranged around the drainage plate with its water collecting opening 11 side facing the drainage plate.

The advantages of the sump 1 and the sump assembly 2 for the planted roof siphon drainage system of the underground garage of the present invention include, for example: first, the transverse compressive capacity of the sump 1 is improved by the transverse reinforcement structure having the reinforcing strands 10 . The lateral reinforcement structure or the reinforcement strand 10 can effectively resist the lateral component force, thereby preventing the lateral displacement or even lateral collapse of the material of the arch section 6; The longitudinal strengthening structure formed by 9 makes the compressive capacity of the sump 1 strengthen. The longitudinal reinforcement structure can strengthen the arched section 6 of the sump 1 longitudinally and to some extent transversely, thereby improving the compressive capacity of the arched section 6 and preventing the arched section 6 from Partially dented or crushed; thirdly, through the precise setting of the position and size of the water collection port 11, the water collection port 11 of the sump 1 is adapted to the structure of the drainage plate, for example, its height. In addition, the water collection port 11 adopts a trumpet design, which is large on the outside and small on the inside, so as to reduce the resistance of water entering the sump 1 and reduce the confluence time, so that the water on the drainage plate can flow into the sump 1 more quickly, thereby effectively controlling The water level of the roof of the underground garage in the case of heavy rain; Fourth, the connection mode of each part of the sump assembly is a form-lock connection and a tenon-tenon connection, which is more convenient for disassembly and installation, and convenient for on-site construction. The mating surface is designed so that the connected sump 1 or sump assembly 2 has a smooth transition between its outer side and inner side.
