Description

Curved four-way drainage channel

Technical Field

The invention relates to the field of drainage, in particular to a curved four-way drainage channel.

Background

At present, a siphon rainwater drainage system is widely applied to a planting roof and a planting roof, a layer of waterproof plate is firstly paved on a building, a garage or a road surface, then water collecting plates are paved on the waterproof plate, and a drainage channel is connected between the water collecting plates. Then a layer of geotextile is laid above the water collecting plate and the water drainage tank, and greening soil is backfilled at the top of the geotextile. Penetrating water in the soil penetrates through the geotextile to enter the water collecting plate, then flows into the drainage grooves through the water inlets on two sides of the drainage grooves, and finally enters the reservoir from the drainage grooves. This system mainly utilizes hydrocone type water drainage tank to produce the siphon effect, collects the infiltration water to the cistern in, irrigates to roofing afforestation or ground vegetation and sprays, when realizing the plumbing, satisfies energy-concerving and environment-protective requirement. The drainage channels are usually arranged on the planting roof or planting roof in a checkerboard manner. And at the crossing position of the drainage channels in the transverse and longitudinal directions, the four-way drainage channels are used for connecting the peripheral straight-through drainage channels.

In the prior art, the four-way drainage channel has a simple structure, and the internal channels of the four-way drainage channel are communicated in a cross way. Under the siphon action, the permeated water in the straight-through drainage grooves in different directions quickly flows into the four-way drainage groove, and then mutual impact is easily generated in the center to form turbulent flow. The kinetic energy of the seepage water is greatly reduced, and the flow speed of the seepage water flowing out of the four-way drainage groove is reduced, so that the drainage efficiency of the siphon rainwater drainage system is influenced.

Disclosure of Invention

The invention aims to overcome the defects of the prior art and provides a curved four-way drainage channel which is used for solving the problem that the four-way drainage channel is easy to form the opposed flushing and turbulent flow of the seepage water and achieving the effects of accelerating the flow speed of the merged seepage water and improving the drainage efficiency of a system.

The invention adopts the technical scheme that the curved four-way drainage channel comprises a first port, a second port, a third port, a fourth port and a first channel, a second channel, a third channel, a fourth channel and a fourth channel, wherein the first port, the second port, the third port and the fourth port are used for connection, the first channel, the second channel and the fourth channel are corresponding to the ports, and the first channel, the second channel, the third channel and the fourth channel are communicated with each other at the intersection. The first channel to the third channel are in a curve shape trend, and the included angle between the first channel to the third channel and the fourth channel when the first channel to the third channel are converged at the junction is an acute angle; the first port to the fourth port are provided with connecting structures used for being connected with other drainage grooves.

In the scheme, the first port to the fourth port refer to a first port, a second port, a third port and a fourth port; the first to fourth channels refer to a first channel, a second channel, a third channel, and a fourth channel. The design of the curve type trend from the first channel to the third channel of the four-way drainage channel ensures that the permeated water entering the channels are independent and do not influence each other. The angle at which the first to fourth channels meet at the intersection is the angle at which the permeate water flows in the first to fourth channels. The angle of the fourth channel is used as a reference, and the included angle between the first channel and the third channel when the first channel and the third channel are respectively merged with the fourth channel at the intersection is an acute angle, so that the condition that the permeated water is not directly collided but is merged at a certain angle when being merged is ensured, the formation of vortex by the permeated water is facilitated, the speed of the permeated water is accelerated, and the problems that the permeated water is easily collided and turbulent flow is easily formed in a four-way water drainage groove are solved. The permeating water at the junction finally flows out rapidly through the fourth channel. The first port to the fourth port of the curved four-way drainage groove are generally distributed in a cross shape, but can also be distributed in a tree branch shape. The shape of the first to fourth ports is determined according to the shape of other drain grooves connected thereto. The first port to the fourth port are generally the same shape, or the fourth port is larger than the first port to the third port.

Preferably, the first port to the fourth port are distributed in a cross shape; the first port points to the third port as the up-down direction, and the second port points to the fourth port as the left-right direction; the junction is non-centered and is biased toward the fourth port. The first port is aligned with the center of the third port and the second port is aligned with the center of the fourth port. The first port and the fourth port are distributed in a cross shape, so that a four-way drainage groove in the prior art can be directly replaced, and the system upgrading is completed. And the cross center is taken as a reference, and the intersection is arranged at one side deviated to the fourth port by adopting a design of deviating from the center. The length of fourth passageway is the shortest, kinetic energy loss when can reducing the infiltration water and flow out further makes the infiltration water of intersection can flow out four-way water drainage tank fast.

Further, the first channel has a direction: starting from the first port downwards, sequentially deviating in the left direction and the right direction, and then connecting to the junction; the direction of the second channel is as follows: starting from the second port to the right, sequentially shifting in the upper direction, the lower direction and the upper direction, and connecting to the junction; the direction of the third channel is as follows: starting from the third port upwards, sequentially offsetting in the left direction and the right direction, and connecting to the junction. The first and third lanes complete 2 shifts and the second lane completes 3 shifts, respectively. The first channel to the third channel all include the smooth curve of multistage, and the corner also is provided with the circular arc transition. In order to improve the compact structure of the four-way drainage channel, the outer wall parts of the first channel and the second channel are overlapped, and the outer wall parts of the second channel and the third channel are overlapped; the outer walls of the first and third channels extend toward the fourth port, forming an outer wall of the fourth channel.

Preferably, the cross-sectional areas of the first to third passages are smaller than the cross-sectional areas of the first to third ports, respectively. The first channel and the first port are taken as an example for explanation, and other channels and other ports are similar. The cross-sectional shape of the first channel and the cross-sectional shape of the first port may be similar or different; the cross-sectional shape tapers from the first port through the first passageway and the cross-sectional area also tapers. After the seepage water flows in through the first port, the flow speed of the seepage water is gradually accelerated in the first channel, then the seepage water reaches the intersection to form a vortex, and finally the seepage water flows out quickly through the fourth channel, so that the drainage efficiency of the four-way drainage groove is further improved.

Preferably, the junction is provided with a boss for guiding the permeated water.

Further, the first channel connects to the junction from the left and right sides of the boss; the second channel connects to the junction at an angle tangential to the left side of the boss; the third passage connects to the intersection at an angle tangent to the right side of the boss.

Further, the cross-sectional dimension of the boss becomes gradually smaller with height.

The boss is equivalent to an annular island at the junction and can guide the seepage water flowing from the first channel to the third channel. The number of the bosses can be one or more according to the direction of the permeated water guided by the intersection, and the shape of the bosses can be a cylinder or a circular truncated cone or a table or a column consisting of other curved surfaces. The boss is arranged on one side deviated to the fourth port and staggered with the center of the fourth port. The permeating water flowing out of the first channel is divided into water flows on the left side and the right side by the lug boss; the left water flow downwardly surrounds the boss, and the right water flow rightwards surrounds the boss. The seepage water flowing out of the second channel flows in at an angle which inclines upwards and is tangential to the left side of the boss; a portion of the permeate water surrounds the bosses upward and another portion of the permeate water surrounds the bosses downward. The seepage water flowing out of the third channel flows in at an angle which inclines upwards and is tangent with the right side of the boss; the permeate water surrounds the boss upwards and rightwards. The permeating water flowing out from different channels is guided by the lug bosses to be circularly converged, and finally the permeating water flows out through the fourth channel. When the seepage water flowing out from the first channel to the third channel gradually increases, the boss occupies a certain space at the intersection, so that the seepage water at the intersection can be blocked, and the cross section size of the boss can be gradually reduced along with the height, so that the situation can be effectively weakened. Further, the height of the boss is 1/3-2/3 of the height of the intersection. If the height of the lug boss is too low, the guiding effect of the seepage water flowing from the first channel to the third channel cannot be exerted; the height of the boss is too high, so that the permeation water flowing from the first channel to the third channel is easily blocked, and the resistance is increased.

Preferably, the connecting structure on the first port to the fourth port is a snap structure.

Further, the buckle structure comprises a male buckle and a female buckle; when the first port and the second port are arranged to be male buckles, the third port and the fourth port are arranged to be female buckles; when the first port and the second port are arranged as female buckles, the third port and the fourth port are arranged as male buckles.

The existing four-way drainage channel and the straight-through drainage channel mostly adopt a clamping groove structure, one end of the drainage channel is provided with a convex strip, and one end of the other drainage channel is provided with a groove. When the drainage groove is connected, one end of the groove of one drainage groove is buckled with one end of the convex strip of the other drainage groove from top to bottom. The draw-in groove structure is flexonics, and when the mounting surface unevenness, it is weak to combine the adaptability, easily causes the junction perk, and the part separates about sand grip and the recess. During backfill construction, under the action force in the side direction of the straight-through drainage channel, the straight-through drainage channel and the four-way drainage channel are easy to be disconnected, and the construction efficiency is influenced. This scheme carries out rigid connection with straight-through water drainage tank and cross water drainage tank through buckle structure. The surfaces from the first port to the fourth port of the four-way drainage channel are respectively provided with a small head or a big head, wherein the small head is a male buckle, and the big head is a female buckle. The male buckle comprises a convex hemisphere which is positioned at the upper part of the port and plays a role in limiting, and a hanging hook which is positioned at the lower part of the port and plays a role in fixing. The box includes the indent hemisphere that is located port upper portion and plays limiting displacement and the grafting limit of its fixed action that is located the port lower part. When the four-way drainage groove and the straight-through drainage groove are connected with each other, the female buckle end of one drainage groove is hung at the male buckle end of the other drainage groove from top to bottom, and the concave hemisphere is matched with the convex hemisphere. The drainage groove is continuously rotated downwards, so that the hanging edge of the drainage groove is buckled on the hanging hook under the action of external force.

The description is continued by taking an example in which the third port and the fourth port are configured as a female buckle when the first port and the second port are configured as a male buckle. When the straight-through drainage channel is arranged, the straight-through drainage channel is usually connected in sequence through the sequence of male buckle-female buckle or female buckle-male buckle, therefore, at the crossing position of the straight-through drainage channel in the transverse direction and the longitudinal direction, both ends of the four-way drainage channel in the transverse direction or the longitudinal direction necessarily need to be provided with the buckle structures of the male buckle-female buckle or the female buckle-male buckle. The first port, the third port, the second port and the fourth port are designed to be a pair of male buckle-female buckle structures, so that the increase of a switching structure can be avoided, and the installation of the four-way drainage groove is convenient and simplified.

In the prior art, the four-way drainage channel is generally produced in batches by using an injection molding method, the scheme can adopt an integral design or a split design, the integral design is simple and convenient to install, but the injection molding production process is complex; the split design is slightly complicated to install, but the injection molding production process is simple.

Preferably, the four-way drainage channel is designed in a split mode and consists of a base and an upper cover; the base comprises a bottom plate part and a lower channel part, and the lower channel part is fixed on the bottom plate part; the upper cover comprises a cover plate member and an upper channel member, and the upper channel member is fixed on the cover plate member; the bottom plate member surface, the cover plate member surface, the lower channel member and the upper channel member together constitute the first channel to the fourth channel. First port to fourth port and buckle structure are located the apron piece of upper cover. The boss at the intersection is located on the bottom plate member of the base. The surface of the cover plate part is smooth, and the upper surface is provided with a handle.

Further, the cross-section of the lower channel member is narrower at the bottom and wider at the top. The cross-sectional shape of the lower channel member may be V-shaped or U-shaped, etc. When the infiltration water passes through lower passageway spare, because the cross sectional area of bottom is little, the velocity of flow will accelerate, has avoided the impurity of infiltration aquatic to deposit in lower passageway spare, prevents that long-term back cross drainage tank from being blockked up by impurity, and then influences the drainage efficiency of system. In addition, the cross section of the existing through drainage channel is generally in an inverted U shape or other similar shape, and the cross section of the through drainage channel is wider at the bottom and narrower at the top, just opposite to the lower channel member. Therefore, the lower channel piece is also provided with a relevant transition curved surface. The cross section of the lower channel part from the first port to the fourth port is matched with the cross section of the straight-through drainage channel and gradually changes into the cross section with a narrower bottom and a wider upper part through a transition curved surface.

Furthermore, flanges are arranged around the bottom plate part; the cover plate piece and the blocking edge are matched in shape, and the upper cover and the base are fixed in position. The flanges comprise a plurality of strips which are respectively connected with the opening ends in the lower channel piece in sequence, and the overall shape of the flanges is similar to that of the upper cover. The flanges form a plurality of steps on the surface of the bottom plate piece, and the mutual plane movement of the upper cover and the base is limited through the matching of the side surfaces of the cover plate piece and the steps.

Furthermore, the surface of the cover plate piece is also provided with reinforcing ribs, and the peripheral edge of the cover plate piece is also provided with an upper edge. After the four-way drainage channel is installed, backfilling operation is required, so that the reinforcing ribs can effectively improve the strength of the upper cover. After the upper cover covers the base, the upper edge is aligned with the edge of the bottom plate piece of the base, on one hand, the attractiveness of the four-way drainage channel is improved, and on the other hand, the anti-overturning capacity of the upper cover is improved.

Compared with the prior art, the invention has the beneficial effects that:

according to the scheme, the design of curve type trend is carried out on the first channel to the third channel of the four-way drainage groove, so that the permeation water entering the channels is independent and does not influence each other. The permeated water from the first channel to the third channel is converged at the intersection through the spirally distributed angles instead of direct 90-degree hedging, so that the permeated water is favorable for forming a vortex, the speed of the permeated water is increased, and the problems that the cross drainage channel is easy to form hedging and turbulent flow of the permeated water are solved.

According to the scheme, through the variable cross-section design from the first channel to the third channel, after the seepage water flows in through the first port, the flow speed of the seepage water is gradually accelerated in the first channel, then the seepage water reaches the intersection to form a vortex, and finally the seepage water flows out quickly through the fourth channel, so that the drainage efficiency of the four-way drainage groove is further improved.

According to the scheme, the bosses are arranged at the intersection, so that the permeation water flowing from the first channel to the third channel is guided to form a vortex more easily, and the flow speed of the permeation water after confluence is further accelerated.

Detailed Description

The drawings are only for purposes of illustration and are not to be construed as limiting the invention. For a better understanding of the following embodiments, certain features of the drawings may be omitted, enlarged or reduced, and do not represent the size of an actual product; it will be understood by those skilled in the art that certain well-known structures in the drawings and descriptions thereof may be omitted.

Example 1

As shown in fig. 1 to 7, the present embodiment is a curved four-way drain tank, which includes first to fourth ports 11 to 14 for connection, and first to fourth passages 21 to 24 corresponding to the ports, and the first to fourth passages 21 to 24 communicate with each other at a junction 30. The first channel 21 to the third channel 23 are in a curve shape, and the included angle between the first channel 21 to the third channel 23 and the fourth channel 24 at the junction 30 is an acute angle; the first to fourth ports 11 to 14 are provided with a connection structure for connection with other drain tanks.

In this embodiment, the first port to the fourth port refer to a first port, a second port, a third port, and a fourth port; the first to fourth channels refer to a first channel, a second channel, a third channel, and a fourth channel. By designing the curves from the first channel 21 to the third channel 23 of the four-way drainage channel, the permeated water entering the channels are independent and do not influence each other. The angle at which first to fourth channels 21 to 24 meet at junction 30 is the angle at which permeate water flows in first to fourth channels 21 to 24. The included angle between the first channel 21 and the third channel 23 and the fourth channel 24 at the junction 30 is an acute angle by taking the angle of the fourth channel 24 as a reference, so that the penetration water is not directly opposite-washed but is mixed at a certain angle when being mixed, the formation of vortex by the penetration water is facilitated, the penetration water speed is accelerated, and the problem that the cross-joint water drainage tank is easy to form penetration water opposite-washing and turbulent flow is solved. Permeate water at junction 30 eventually flows out quickly through fourth passage 24. The first port 11 to the fourth port 14 of the curved four-way drainage channel are generally distributed in a cross shape, but may be distributed in a tree branch shape. The shapes of the first to fourth ports 11 to 14 are determined according to the shapes of other drain grooves connected thereto. The first to fourth ports 11 to 14 are generally the same shape, or the fourth port 14 is larger than the first to third ports 11 to 13. This embodiment is used in combination with a straight through drainage channel of n-type cross-section, so that the first to fourth ports 11 to 14 are also of corresponding n-type.

Preferably, the first port 11 to the fourth port 14 are distributed in a cross shape; the first port 11 points to the third port 13 as the up-down direction, and the second port 12 points to the fourth port 14 as the left-right direction; the junction 30 is not centered and is offset from the fourth port 14. The first port 11 is aligned with the center of the third port 13 and the second port 12 is aligned with the center of the fourth port 14. The first port 11 to the fourth port 14 are distributed in a cross shape, so that a four-way drainage groove in the prior art can be directly replaced, and system upgrading is completed. The intersection 30 is disposed at a side offset to the fourth port 14 by taking the center of the cross as a reference. The length of the fourth channel 24 is the shortest, which can reduce the kinetic energy loss when the permeate water flows out, and further make the permeate water at the junction 30 flow out of the four-way drainage channel quickly.

Further, the first channel 21 runs as follows: starting from the first port 11 downwards, sequentially offsetting in the left direction and the right direction, and connecting to the junction 30; the second channel 22 runs in the following direction: starting from the second port 12 to the right, sequentially deviating in the upper direction, the lower direction and the upper direction, and then connecting to the junction 30; the third channel 23 runs as follows: starting from the third port 13, the first and second ports are sequentially offset in the left and right directions and then connected to the junction 30. The first and

third channels

21 and 23 respectively complete 2 shifts and the second channel 22 completes 3 shifts. The first channel 21 to the third channel 23 each include a plurality of smooth curves, and arc transitions are also provided at corners. In order to improve the compact structure of the four-way drainage channel, the outer wall parts of the first channel 21 and the second channel 22 are overlapped, and the outer wall parts of the second channel 22 and the third channel 23 are overlapped; the outer walls of the first and

third channels

21, 23 extend towards the fourth port 14, forming the outer wall of the fourth channel 24.

Preferably, the junction 30 is provided with a boss 31 for guiding the permeate water.

Further, the first passage 21 connects to the junction 30 from the left and right sides of the boss 31; the second channel 22 connects to junction 30 at an angle tangential to the left side of boss 31; the third passageway 23 connects to the junction 30 at an angle tangential to the right side of the boss 31.

Further, the cross-sectional size of the boss 31 becomes gradually smaller with height.

The projection 31 corresponds to an island at the junction 30 and guides the permeate flowing from the first passage 21 to the third passage 23. The number of bosses 31 may be one or more, and the shape of the bosses 31 may be a cylinder or a truncated cone or a table or a column made of other curved surfaces, depending on the direction of the permeate directed at the junction 30. The boss 31 is provided on a side offset to the fourth port 14 and is offset from the center of the fourth port 14. The permeated water flowing out of the first passage 21 is divided into left and right water flows by the boss 31; the left water stream is directed downward around the boss 31 and the right water stream is directed rightward around the boss 31. Permeate from second channel 22 flows in at an angle obliquely upward and tangential to the left side of boss 31; a portion of the permeate water surrounds the boss 31 upwardly and another portion of the permeate water surrounds the boss 31 downwardly. Permeate from the third channel 23 flows in at an angle obliquely upward and tangential to the right side of the boss 31; permeate water passes right up around boss 31. The permeate water from the different channels is guided by the bosses 31 to join around, and finally flows out through the fourth channel 24. When the amount of the permeate water flowing out from the first channel 21 to the third channel 23 is gradually increased, the boss 31 occupies a certain space at the junction 30, the permeate water at the junction 30 is blocked, and the cross-sectional size of the boss 31 is gradually reduced along with the height, so that the above situation can be effectively reduced. Further, the height of the boss 31 is 1/3-2/3 of the height of the junction 30. If the height of the boss 31 is too low, the guiding effect of the permeated water flowing from the first channel 21 to the third channel 23 is not exerted; the height of the boss 31 is too high, and it is easy to form a barrier to the permeation water flowing in from the first channel 21 to the third channel 23, increasing resistance.

As shown in fig. 7 and 8, the first port 11 to the fourth port 14 are preferably provided with a snap structure 60 for connection. Further, the snap structure 60 includes a male buckle 61 and a female buckle 62; in this embodiment, the first port 11 to the fourth port 14 are all female fasteners 62, and the corresponding port for connection that leads to the drainage channel is a male fastener 61.

The existing four-way drainage channel and the straight-through drainage channel mostly adopt a clamping groove structure, one end of the drainage channel is provided with a convex strip, and one end of the other drainage channel is provided with a groove. When the drainage groove is connected, one end of the groove of one drainage groove is buckled with one end of the convex strip of the other drainage groove from top to bottom. The draw-in groove structure is flexonics, and when the mounting surface unevenness, it is weak to combine the adaptability, easily causes the junction perk, and the part separates about sand grip and the recess. During backfill construction, under the action force in the side direction of the straight-through drainage channel, the straight-through drainage channel and the four-way drainage channel are easy to be disconnected, and the construction efficiency is influenced. The embodiment rigidly connects the straight-through drainage channel and the four-way drainage channel through the buckle structure 60. The surfaces of the first port 11 to the fourth port 14 of the four-way drainage groove are respectively provided with a small head or a big head, wherein the small head is a male buckle 61, and the big head is a female buckle 62. The male buckle 61 comprises a convex hemisphere located at the upper part of the port for limiting, and a hook located at the lower part of the port for fixing. The female snap 62 includes a concave hemisphere for limiting located at the upper part of the port, and a hanging edge for fixing located at the lower part of the port. When the four-way drainage groove and the straight-through drainage groove are connected with each other, the female buckle 62 end of one drainage groove is hung at the male buckle 61 end of the other drainage groove from top to bottom, and the concave hemisphere is matched with the convex hemisphere. The drainage groove is continuously rotated downwards, so that the hanging edge of the drainage groove is buckled on the hanging hook under the action of external force.

As shown in fig. 1-7, the four-way drainage channel of the present embodiment adopts a split design, and is composed of a base 40 and an upper cover 50; the base 40 comprises a bottom plate member 41 and a lower channel member 42, the lower channel member 42 is fixed on the bottom plate member 41; the upper cover 50 includes a cover member 51 and an upper channel member 52, the upper channel member 52 being fixed to the cover member 51; the floor member 41 surface, the deck member 51 surface, the lower channel member 42 and the upper channel member 52 collectively constitute the first through fourth channels 21 through 24. The first to fourth ports 11 to 14 and the snap structure 60 are located on the deck member 51 of the upper cover 50. The boss 31 of the junction 30 is located on the floor member 41 of the base 40. The deck member 51 has a smooth surface, an upper surface and is provided with a handle.

The floor member 41 of this embodiment is an octagonal plate member, and a lower channel member 42 is fixed to an upper surface thereof. The lower channel members 42 are a plurality of curved plate members. The first to fourth ports 11 to 14 are notched at corresponding positions on the bottom plate member 41, and the open end of the lower passage member 42 is stopped at the notched positions. The deck member 51 is an octagonal shaped cover with the lower channel member 42 secured to the lower surface. The lower channel members 42 are a plurality of curved plate members. The cover member 51 is provided with an opening at a side surface thereof and extends outward, forming the first port 11 to the fourth port 14. The open end of the upper channel member 52 ends at the opening position of the first port 11 to the fourth port 14. After the upper cover 50 is assembled with the base 40, the lower channel member 42 is overlapped with the edge of the upper channel member 52, and forms the first channel 21 to the fourth channel 24 together with the upper surface of the bottom plate member 41 and the lower surface of the cover plate member 51; the open ends of the lower and

upper channel members

42 and 52 are fitted to the sides of the first to fourth ports 11 to 14. The base 40 and the upper cover 50 of the present embodiment are manufactured by injection molding and integral molding, respectively.

Further, the cross-section of the lower channel member 42 is narrower at the bottom and wider at the top, as shown in fig. 9. The cross-sectional shape of the lower channel member 42 may be V-shaped or U-shaped, etc. When permeate water passes through lower passageway piece 42, because the cross sectional area of bottom is little, the velocity of flow will accelerate, has avoided the impurity of permeate water to deposit in passageway piece 42 down, prevents that long-term back four-way water drainage tank from being blockked up by impurity, and then the drainage efficiency of influence system. In addition, the cross-section of the conventional through drain channel is generally in the shape of an inverted U or the like, with the cross-section of the through drain channel being wider at the bottom and narrower at the top, just opposite the lower channel member 42. Accordingly, the lower channel piece 42 is also provided with an associated transition surface. The cross section of the lower channel member 42 from the first port 11 to the fourth port 14 matches the cross section of the through drain channel, gradually changing to a cross section with a narrower bottom and a wider top through a transitional curved surface.

Furthermore, flanges 43 are arranged around the bottom plate 41; the cover plate 51 and the rib 43 are matched in shape, so that the upper cover 50 and the base 40 are fixed in position. The rib 43 comprises a plurality of strips, each of which is connected to the open end of the lower channel member 42 in sequence, and the overall shape of the rib is similar to that of the upper cover 50. The ribs 43 form steps on the surface of the base member 41, and the side surfaces of the cover member 51 cooperate with the steps to limit the planar movement of the cover 50 and the base 40 relative to each other.

Further, the surface of the deck member 51 is provided with a reinforcing rib, and the peripheral edge of the deck member 51 is provided with an upper edge 53. Since the four-way drainage channel needs to be backfilled after being installed, the reinforcing ribs can effectively improve the strength of the upper cover 50. After the upper cover 50 covers the base 40, the upper edge 53 is aligned with the edge of the bottom plate 41 of the base 40, so as to improve the aesthetics of the four-way drainage channel on one hand, and improve the anti-overturning capability of the upper cover 50 on the other hand. The reinforcing ribs of the deck member 51 of the present embodiment are distributed from the center of the upper surface toward eight corners of the octagon and extend downward along the side surfaces of the deck member 51. The upper rim 53 is also simultaneously aligned with the sides of the first port 11 to the fourth port 14.

Example 2

The present embodiment is a curved four-way drainage channel, which has a similar structure to that of embodiment 1, and the same structure will not be described again, and only the structure different from that of embodiment 1 will be described below. The present embodiment employs an integral design, namely: the base and the upper cover are integrally formed. In addition, the first channel to the fourth channel are round tubes, and the cross section of each channel is circular.

Preferably, the cross-sectional areas of the first to third passages are smaller than the cross-sectional areas of the first to third ports, respectively. The first channel and the first port are taken as an example for explanation, and other channels and other ports are similar. The cross-sectional shape of the first channel and the cross-sectional shape of the first port may be similar or different; the cross-sectional shape tapers from the first port through the first passage and the cross-sectional area also tapers. After the seepage water flows in through the first port, the flow speed of the seepage water is gradually accelerated in the first channel, then the seepage water reaches the intersection to form a vortex, and finally the seepage water flows out quickly through the fourth channel, so that the drainage efficiency of the four-way drainage groove is further improved.

In this embodiment, the fastening structure includes a male buckle and a female buckle; when the first port and the second port are arranged to be male buckles, the third port and the fourth port are arranged to be female buckles; when the first port and the second port are arranged as female buckles, the third port and the fourth port are arranged as male buckles.

The description is continued by taking an example in which when the first port and the second port are set as the male snap, the third port and the fourth port are set as the female snap. When the straight-through drainage channel is arranged, the straight-through drainage channel is usually connected in sequence through the sequence of male buckle-female buckle or female buckle-male buckle, therefore, at the crossing position of the straight-through drainage channel in the transverse direction and the longitudinal direction, both ends of the four-way drainage channel in the transverse direction or the longitudinal direction necessarily need to be provided with the buckle structures of the male buckle-female buckle or the female buckle-male buckle. The first port, the third port, the second port and the fourth port are designed to be a pair of male buckle-female buckle structures, so that the increase of a switching structure can be avoided, and the installation of the four-way drainage groove is convenient and simplified.

It should be understood that the above-mentioned embodiments of the present invention are only examples for clearly illustrating the technical solutions of the present invention, and are not intended to limit the specific embodiments of the present invention. Any modification, equivalent replacement, and improvement made within the spirit and principle of the present invention claims should be included in the protection scope of the present invention claims.
