Abstract
Description
[0001] This application is a divisional application of the Chinese invention patent application filed on August 8, 2018, with the invention name “Drainage Device” and application number 201810896415.X. Technical Field
[0002] The invention relates to a drainage device. Background Art
[0003] In order to quickly drain the infiltrated water and / or rainwater, currently available infiltration and drainage devices mainly include drainage pipes, drainage ditches, water collection well boxes and well covers.
[0004] Existing drainage pipes are mainly divided into gravel blind ditch, plastic blind ditch, soft permeable pipe, various perforated pipes, etc. Among them, gravel blind ditch is made of gravel wrapped with geotextile, which has low porosity, poor drainage effect and easy clogging.
[0005] Plastic blind drains include round tubes, round reinforced tubes, rectangular tubes, rectangular reinforced tubes, round solid tubes, and square solid tubes. However, plastic blind drains still have disadvantages such as being unable to bend, not resistant to high temperatures, and having narrow drainage channels. The soft permeable pipe is supported by sparse spring tubes in the middle and is covered with non-woven polyester yarn as a filter layer. Although it can be bent, it is not resistant to high temperatures and has poor pressure resistance. At the same time, the spring skeleton that plays a supporting role in the permeable pipe is also easily lost due to rust. Various perforated pipes are holes punched on the pipe wall to form seepage and drainage holes. A small number of products, such as single-wall corrugated pipes, can be bent, but the drainage effect of perforated pipes with low opening rates is not good, and pipes with high opening rates have poor pressure resistance. At the same time, secondary processing of the pipe body will also increase unnecessary costs such as handling fees, freight, and hole opening fees.
[0006] Existing drainage ditches are mainly divided into resin concrete drainage ditches and HDPE finished drainage ditches. The side walls of these two types of drainage ditches are impermeable walls. In order to make the wall body permeable, it is necessary to punch holes on the side walls twice. There are also problems such as poor drainage effect of walls with low opening rate, poor compressive performance of walls with high opening rate, and additional costs due to secondary processing; in addition, these two types of drainage ditches cannot be bent. For HDPE finished drainage ditches, it also has defects such as poor compressive performance and high temperature resistance, which affect its application occasions. For resin concrete drainage ditches, their walls are thicker, which makes the drainage channel smaller and affects the drainage effect. In addition, resin concrete drainage ditches are heavy and difficult to carry and install.
[0007] The existing water collection well boxes are mainly divided into two types: iron well boxes and ductile iron well boxes. Among them, the iron well boxes have poor compressive performance; at the same time, the box bodies of iron well boxes and ductile iron well boxes generally do not have seepage and drainage holes. If you need to add seepage and drainage holes to improve drainage efficiency, you also need to drill holes twice. There are also problems such as poor drainage effect of walls with low opening rates, poor compressive performance of walls with high opening rates, and additional costs for secondary processing.
[0008] Existing manhole covers mainly include grille manhole covers, circular drain hole manhole covers and slot manhole covers that are used in conjunction with finished drainage ditches and water collection well boxes. The drainage channels of these manhole covers are generally straight up and down, and they have the disadvantage of being easily blocked. Summary of the invention

[0090] In multiple embodiments of the drainage device, the drainage device can be a drainage pipe, a drainage ditch, an anti-blocking permeable water collection well, or an anti-blocking well cover.
[0091] Figures 1A to 10 Various embodiments of the drainage device are shown. In these embodiments, the drainage device is a drainage pipe. It is mainly used for drainage of water between asphalt layers and other fields that require drainage, such as: vertical and horizontal drainage on the back of various retaining walls; drainage of highway and railway roadbeds, shoulders, and soft soil foundations; drainage of tunnels and underpasses; drainage of power ash dams and water conservancy dams; drainage of central isolation zones on highways and protection of vegetation; drainage of outdoor sports venues; horizontal drilling drainage; drainage and slope protection of easily collapsed land; drainage of roof gardens and flower beds; drainage of underground garage roofs; drainage of hillsides; underground drainage of land preparation projects, drainage of low-lying land, and saline-alkali land transformation systems, etc., to replace soft permeable pipes, plastic blind ditches, and various perforated pipes. At the same time, Figures 1A to 10 Drain pipes of various shapes are provided to meet the requirements of pressure resistance, drainage volume, etc. under different construction conditions.
[0092] Please see Figures 1A to 1C In one embodiment of the drain pipe, the drain pipe includes a plurality of ribs 12. The plurality of ribs 12 are connected end to end into a whole and are spirally shaped, which constitute a tubular water-permeable wall 11 of the drain pipe. Figure 1B and Figure 1CIt can be seen from the content shown that when the drain pipe is viewed along the axial direction, the drain pipe is in a circular ring shape. The cross section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outside of the circumferential direction of the drain pipe, and the crest of one rib and the trough of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross section gradually decreases from the outside to the inside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inside of the drain pipe, so that the inner wall surface of the plurality of ribs 12 is cylindrical, and the outer wall surface is wavy on the cylindrical surface. In the vertical projection of the permeable wall 11, the inner surface of one of the adjacent ribs overlaps with the outer surface of another rib, so that when the permeable wall 11 of the drain pipe is observed in the vertical direction, the gap on the surface of the permeable wall 11 of the drain pipe is blocked by the inner and outer surfaces of the multiple ribs 12, so that the debris outside the drain pipe is not easy to enter the drain pipe from the gap on the permeable wall 11 to block the drain pipe. While not affecting the drainage performance of the drain pipe, it plays a role in preventing the inside of the drain pipe from being blocked. At the same time, when the drain pipe is buried under the road surface, the outer wall surface of the multiple ribs 12 of the drain pipe can be more tightly bonded with the buried materials outside the drain pipe. At the same time, under the condition of the same wall thickness, more raw materials can be saved, and under the condition of the same caliber, longer pipes can be produced, making the construction lighter and more green and environmentally friendly.
[0093] In one embodiment, the drain pipe is made of plastic material, and its molding method can be but not limited to injection molding, extrusion molding and other suitable plastic molding processes, so that the drain pipe is not easily corroded during the application process, and the plastic drain pipe can be cut with scissors or utility knife, and the plastic drain pipes of the same caliber will be lighter and more convenient to carry and construct. At the same time, when the plastic drain pipe is used in the asphalt pavement, when the asphalt surface layer is damaged and needs to be milled, the plastic drain pipe can be reused as part of the asphalt mixture. In one embodiment, the drain pipe is made by rotating the nozzle, and the length of a spring tube with an inner diameter of 15mm can be up to 120 meters. At the same time, the larger the diameter, the shorter it is, but a 45mm diameter spring tube can reach 30m per tube, so fewer joints need to be connected, so that the construction quality is more guaranteed. In another embodiment, the drain pipe can also be made of metal material.
[0094] In some embodiments, the multiple ribs 12 of the multiple sections of drainage pipes can be connected by welding, bonding or snapping.
[0095] like Figure 2As shown, in one embodiment, any adjacent ribs among the plurality of ribs 12 in the drainage pipe are connected in an elastically expandable manner, so that the drainage pipe is easy to expand and contract and bend. When used in various construction orientations, the bendable drainage pipe can better fit the orientation of the construction or road surface, and can reduce the gap between the drainage pipe and the building or road surface, thereby improving the drainage efficiency and preventing garbage and other debris from accumulating in the gap between the drainage pipe and the road surface.
[0096] Figures 1A to 1C There are also variations in the embodiment of the drain pipe shown: Figures 3A to 3C As shown, in the wavy cross section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude is a gradual change from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and is reduced to 0 on the outside of the drain pipe, so that the outer wall surface of the plurality of ribs 12 is cylindrical, and the inner wall surface is a wavy shape on the cylindrical surface. At this time, when observing along the vertical direction of the permeable wall body 11 of the drain pipe, the surface gap of the permeable wall body 11 of the drain pipe will also be mutually blocked by the inner and outer surfaces of the plurality of ribs 12, which can also play a role in preventing the inside of the drain pipe from being blocked.
[0097] like Figures 4A to 4C As shown, in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into one body and are in a spiral shape. Figure 4B and 4C When viewed along the axial direction of the drain pipe, the drain pipe is rectangular. The cross-section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outer side in the circumferential direction of the drain pipe, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outer side to the inner side of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inner side of the drain pipe, so that the inner wall surface of the multiple ribs 12 is a rectangular cylinder, and the outer wall surface is a wave shape on the rectangular cylinder surface. The drain pipe arranged in this embodiment can also serve as follows. Figures 1A to 1C In the drain pipe shown, the drain pipe has an anti-blocking effect inside. At the same time, since the drain pipe is rectangular when viewed along the axial direction of the drain pipe, when the drain pipe is placed on a plane, it will not roll in the circumferential direction.
[0098] FIG. 4A to FIG. 4C The drain pipe shown in the figure also has variations: for example, in the wavy cross-section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude thereof gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe, so that the outer wall surface of the plurality of ribs 12 is a rectangular cylinder, and the inner wall surface is a wavy shape on the rectangular cylinder surface.
[0099] like Figures 4D to 4FAs shown in FIG. 1 , in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into a whole and are spirally shaped. When viewed along the axial direction of the drain pipe, the radial profile of the drain pipe is as follows: Figure 4E As shown: the outside is rectangular and the inside is arched, and the drainage device is divided into two parts in the upper and lower directions, each of which has a straight side wall 12a and 12b, and the amplitude of the outer surface of the straight side wall 12a in the upper part is 0, and the amplitude of the outer surface of the straight side wall 12b in the lower part increases from the inside to the outside, and the amplitude of the outer surface of the straight side wall 12b reaches the maximum value. Among them, the straight side wall 12a can also be the straight side wall in the lower part, and the corresponding straight side wall 12b can be the straight side wall in the upper part, so that the amplitude of the straight side wall in the lower part is 0, and the amplitude of the outer surface of the straight side wall in the upper part reaches the maximum value. The drainage pipe set in this way has an anti-blocking function and its bottom stability is stronger. At the same time, the user can choose what type of side wall to use as the upper surface according to needs. FIG. 4D to FIG. 4F The drain pipe shown also has variations: for example, the outer contour of the drain pipe can be a suitable shape including but not limited to polygonal, circular, arched, etc. containing at least one straight edge; the inner contour of the drain pipe can also be a suitable shape including but not limited to polygonal, circular, arched, etc.
[0100] like Figures 5A to 5C As shown, in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into one body and are in a spiral shape. Figure 5B and 5C When viewed along the axial direction of the drain pipe, the drain pipe is fan-shaped. The cross-section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outer side in the circumferential direction of the drain pipe, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outside to the inside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inside of the drain pipe, so that the inner wall surface of the multiple ribs 12 is a fan-shaped cylinder, and the outer wall surface is a wave shape on the fan-shaped cylinder. The drain pipe arranged in this embodiment can also function as follows. Figures 1A to 1CIn the drain pipe shown, the drain pipe has an anti-blocking effect inside. At the same time, since the drain pipe is fan-shaped when viewed along the axial direction of the drain pipe, when the drain pipe is placed on a plane, it will not roll in the circumferential direction. In various embodiments, when viewed along the axial direction of the drain pipe, the drain pipe is fan-shaped, and the central angle of the fan can be any value between 0° and 180°. Among them, when the central angle of the fan is 90°, the drain pipe is a right-angle fan-shaped when viewed along the axial direction of the drain pipe; when the central angle of the fan is 180°, the drain pipe is semicircular when viewed along the axial direction of the drain pipe. In one embodiment, when viewed along the axial direction of the drain pipe, the drain pipe is a right-angle fan-shaped. When it is set at the expansion joint position of the bridge, one of the right-angled sides is close to the expansion joint, and the other right-angled side is prevented from being on the bottom plate of the bridge, and the arc surface faces the direction of the vehicle on the bridge. When the vehicle passes the expansion joint, it will first pass through the arc surface and then roll over the expansion joint. Since the right-angled fan-shaped structure is stable, the drain pipe can still maintain the stability of the pipe structure after being rolled for many times. In another embodiment, when viewed along the axial direction of the drain pipe, the drain pipe is arched.
[0101] Figures 5A to 5C The drain pipe shown also has variations: for example, in the wavy cross-section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe, so that the outer wall surface of the multiple ribs 12 is a fan-shaped cylinder, and the inner wall surface is a wave shape on the fan-shaped cylinder.
[0102] Figures 5A to 5C There are other variations of the drain pipe shown: Figures 6A to 6C As shown, when viewed along the axial direction of the drain pipe, the drain pipe is fan-shaped, including an arc-shaped wall 121 and two radial walls 122, and one radial arm 122 protrudes from the arc-shaped wall 121. The amplitude of the wavy cross section of the rib 12 gradually decreases from the outside to the inside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inside of the drain pipe. In another embodiment, the amplitude of the wavy cross section of the rib 12 gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe.
[0103] like Figures 7A to 7C As shown, in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into one body and are in a spiral shape. Figure 7B and 7CWhen viewed along the axial direction of the drain pipe, the drain pipe is square on the outside and circular on the inside. The cross-section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outside in the circumferential direction of the drain pipe, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outside to the inside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inside of the drain pipe, so that the inner wall surface of the multiple ribs 12 is a circular cylinder, and the outer wall surface is a wavy shape on the rectangular cylinder surface. The drain pipe arranged in this embodiment can also serve as follows. Figures 1A to 1C In the drain pipe shown, the drain pipe has an anti-blocking effect. At the same time, since the drain pipe is square outside and round inside when viewed along the axial direction of the drain pipe, when the drain pipe is placed on a plane, it will not roll in the circumferential direction, and the drain pipe with square outside and round inside is more stable in structure.
[0104] Figures 7A to 7C The drain pipe shown in the figure also has changes: for example, in the wavy cross-section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe, so that the outer wall surface of the multiple ribs 12 is a rectangular cylinder, and the inner wall surface is a wavy shape on the cylindrical surface.
[0105] like Figures 8A to 8C As shown, in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into one body and are in a spiral shape. Figure 8B and 8C When viewed along the axial direction of the drain pipe, the drain pipe is triangular. The cross-section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outer side in the circumferential direction of the drain pipe, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outside to the inside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inside of the drain pipe, so that the inner wall surface of the multiple ribs 12 is a triangular cylinder, and the outer wall surface is a wave shape on the triangular cylinder. The drain pipe arranged in this embodiment can also function as follows. Figures 1A to 1C In the drain pipe shown, the drain pipe has an anti-blocking effect inside. At the same time, since the drain pipe is triangular when viewed along the axial direction, the compressive strength of the drain pipe is stronger. When subjected to external force along the radial direction of the drain pipe, the drain pipe is less likely to deform. At the same time, when the drain pipe is placed on a plane, it will not roll in the circumferential direction.
[0106] Figures 8A to 8CThe drain pipe shown in the figure also has changes: for example, in the wavy cross-section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe, so that the outer wall surface of the multiple ribs 12 is a triangular cylinder, and the inner wall surface is a wave shape on the triangular cylinder.
[0107] like Figures 9A to 9C As shown, in another embodiment of the drain pipe, a plurality of ribs 12 constituting the tubular water-permeable wall 11 of the drain pipe are connected end to end into one body and are in a spiral shape. Fig. 9B and 9C When viewed along the axial direction of the drain pipe, the drain pipe is trapezoidal. The cross-section of the rib 12 in the circumferential direction of the drain pipe is wavy, and has alternating crests and troughs on the outer side in the circumferential direction of the drain pipe, and the crest of one rib and the trough of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outer side to the inner side of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the inner side of the drain pipe, so that the inner wall surface of the multiple ribs 12 is a trapezoidal cylinder, and the outer wall surface is a wave shape on the trapezoidal cylinder. The drain pipe arranged in this embodiment can also function as follows. Figures 1A to 1C In the drain pipe shown, the drain pipe has an anti-blocking effect inside. At the same time, when the drain pipe is placed on a plane, it will not roll in the circumferential direction.
[0108] Figures 9A to 9C The drain pipe shown in the figure also has changes: for example, in the wavy cross-section of the ribs 12 in the circumferential direction of the drain pipe, the amplitude thereof gradually decreases from the inside to the outside of the drain pipe along the radial direction of the drain pipe, and decreases to 0 on the outside of the drain pipe, so that the outer wall surface of the plurality of ribs 12 is a trapezoidal cylinder, and the inner wall surface is a wavy shape on the trapezoidal cylinder.
[0109] Please continue to see Fig.10 The opposite ends of any adjacent ribs of the plurality of ribs 12 of the drain pipe are connected by reinforcing ribs and at least one reinforcing rib 128, so that when the drain pipe is subjected to radial external force, the pipe body of the drain pipe will not be deformed. In some embodiments, the reinforcing ribs 128 on any two ribs 12 can be arranged in an angled manner or in a parallel and staggered manner.
[0110] In some embodiments, at least a portion of the inner side or outer side of the plurality of ribs 12 is connected by reinforcing ribs, which further enhances the compressive strength of the drainage pipe.
[0111] In some embodiments, when viewed along the axial direction of the drain pipe, the outer contour of the drain pipe can be, but is not limited to, a suitable shape such as a circle, a polygon, or a sector, and the inner side of the drain pipe can be, but is not limited to, a suitable shape such as a circle, a polygon, or a sector, to meet the requirements of pressure resistance, drainage volume, etc. under different construction conditions.
[0112] In some embodiments, at least a portion of the plurality of ribs 12 of the drain pipe is provided with holes or grooves to form additional drainage channels, further improving drainage efficiency. In one or more embodiments, accessories such as steel wires, steel rods, plastic wires or plastic rods may be added to the holes or grooves to increase the strength of the drain pipe.
[0113] In some embodiments, a filter layer is also provided on the drain pipe. The filter layer allows drainage to enter the drain pipe while preventing mud, debris, etc. from entering the pipe body, thereby further preventing pipe blockage inside the drain pipe. In one or more embodiments, the filter layer may be, but is not limited to, composed of wrapping materials such as silk, cloth, membrane, and a mixture thereof, or may be a reverse filter layer.
[0114] In some embodiments, the plurality of ribs 12 may be made in the form of triangular, quadrilateral, double-wave, spiral or circular ribs.
[0115] In some embodiments, the plurality of ribs 12 are also provided with convex and / or concave patterns on the outer surface of the drain pipe, which can be used to increase the friction of the outer surface of the drain pipe, prevent slipping and beautify the outer surface of the drain pipe.
[0116] like Figures 1A to 10 The various embodiments of the drainage device shown can also be used as various drainage ditches, which have the same characteristics as the drainage pipes in the above-mentioned ways, and can be used for drainage of asphalt pavements of roads and bridges, including drainage of interlayer water, to replace traditional open ditch drainage. It can also be used in drainage ditches on the slopes of landscape garden roads; drainage ditches at railway stations, airports, squares, etc.; transverse drainage ditches on roads; drainage ditches in waiting areas such as bus stations and taxi stands; drainage ditches in swimming pools; drainage ditches in kitchens and bathrooms; underground drainage ditches; drainage ditches on the edge of roof gardens and drainage ditches on the top of underground garages for greening, and other fields that require drainage ditches. At the same time, when the various drainage ditches are installed, they can be partially buried below the road surface, and one side can be used as a drainage ditch cover exposed on the road surface, so there is no need to add an additional cover, which saves costs and avoids the cumbersome operations caused by secondary installation.
[0117] When Figures 1A to 10 The various embodiments of the drainage device shown can also be used as drainage ditches in the following ways:
[0118] When FIG. 5A to FIG. 5C When the various embodiments of the drainage device shown are used as various drainage ditches, the drainage ditches are fan-shaped when viewed along the axial direction of the drainage ditches, and when installed, the curved side of the drainage ditches can be exposed on the road surface and used as drainage ditch covers. When used in underground garages, the curved side of the drainage ditches can be exposed on the road surface and used as speed bumps of the underground garage, so that the drainage ditches and speed bumps are combined into one, simplifying the construction while also saving the construction cost.
[0119] When Figures 8A to 9C When the various embodiments of the drainage device shown are used as various drainage ditches, the drainage ditches are installed upside down when installed on the road surface.
[0120] FIG. 11A to FIG. 11C The drain device is another embodiment of a drain ditch, wherein the plurality of ribs 12 constituting the permeable wall 11 of the drain ditch are U-shaped and have two side arms 124 and a bottom 125. Fig. 11B The adjacent ribs in the plurality of ribs 12 are alternately connected at the top and bottom 125 of the two side arms 124 to form a continuous square wave. Fig. 11C The cross-section of the rib 12 in the direction of the extension of the length of the drainage ditch is wavy, so that the bottom 125 has a wavy shape, and at the same time, there are alternating crests and troughs on the outside of the drainage ditch bottom 125, and the crest of one rib and the trough of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section gradually decreases from the outside to the inside of the drainage ditch bottom 125 along the vertical direction of the drainage ditch bottom 125, and decreases to 0 on the inside of the drainage ditch bottom 125. The gap on the surface of the drainage ditch bottom 125 is mutually blocked by the inner and outer surfaces of the multiple ribs 12, thereby reducing the entry of debris outside the drainage ditch into the drainage ditch through the gap and preventing blockage inside the drainage ditch. At the same time, any adjacent ribs among the multiple ribs 12 are connected in an elastically expandable manner, so that the drainage ditch is easy to expand and contract and bend, and it also plays a role in being easier to fit the construction direction. FIG. 11A to FIG. 11C The drainage ditch shown in the figure also has different variations, such as the amplitude of the wavy cross-section of the plurality of ribs 12 gradually decreases from the inside to the outside of the drainage ditch bottom 125 along the vertical direction of the drainage ditch bottom 125, and decreases to 0 on the outside of the drainage ditch bottom 125. In an embodiment not shown in the figure, FIG. 11A to FIG. 11C At least one reinforcing rib is also provided in the center of the bottom 125 of the drainage ditch shown, protruding upward from the bottom 125 to be flush with the two side arms 124, so as to strengthen the internal structural strength of the drainage ditch.
[0121] Fig.11D Shows FIG. 11A to FIG. 11C A variation of the drainage device, such as Fig.11DAs shown, the plurality of ribs 12 constituting the permeable wall 11 of the drainage ditch are U-shaped, having two side arms 124 and a bottom 125 , and adjacent ribs among the plurality of ribs 12 are alternately connected between the two side arms 124 .
[0122] like FIG. 1A to FIG. 11D The drainage device shown in the figure also has different variations, such as the amplitude of the wavy cross-section of the plurality of ribs 12 of the permeable wall 11 changes nonlinearly, so that the plurality of ribs 12 can have mutually concealing wavy shapes on both the inner and outer sides of the drainage device.
[0123] FIG. 12A to FIG. 15B It shows various implementation methods of the drainage device when it is an anti-blocking permeable water collection well. It is mainly used for drainage of asphalt pavement of roads and bridges, including water collection ports for drainage of interlayer water, and other places where water collection ports or drainage holes are needed in the middle of drainage ditches, such as: used in conjunction with landscape garden road slope drainage ditches; used in conjunction with drainage ditches of railway stations, airports, squares, etc.; used in conjunction with road transverse drainage ditches; used in conjunction with drainage ditches in waiting areas such as bus stations and taxi points; used in conjunction with swimming pool drainage ditches; used in conjunction with kitchen and bathroom drainage ditches; used in conjunction with underground garage drainage ditches; used in conjunction with roof garden edge drainage ditches and underground garage roof greening drainage ditches, etc., so that the interlayer water of the road surface can be drained into the water collection well and rainwater on the road and bridge road surface can be discharged.
[0124] See also Fig. 12A and 12B The anti-blocking permeable water collection well is square, and the water collection well includes four permeable walls 21 and a wellhead 20 surrounded by the four permeable walls 21. The wellhead 20 is used to receive the external water discharge of the water collection well, and the four permeable walls 21 form the surrounding well walls of the water collection well. The permeable wall 21 also includes a plurality of ribs 22, and the cross-section of the plurality of ribs 22 in the circumferential direction of the well wall of the water collection well is wavy, and has alternating crests and troughs on the outside of the well wall of the water collection well, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross-section of the rib 22 gradually decreases from the outside to the inside of the well wall of the water collection well along the thickness direction of the well wall of the water collection well, and decreases to 0 on the inside of the well wall of the water collection well. A drainage pipe is also connected to the bottom of the water collection well to discharge the water in the water collection well. The gaps on the surface of the water collection well wall are mutually shielded by the inner and outer surfaces of multiple ribs 22, thereby reducing the amount of debris outside the drainage ditch entering the water collection well through the gaps, preventing blockage inside the water collection well, and allowing interlayer water under the road surface to flow into the water collection well through the gaps on the water collection well wall. And compared with the traditional way of opening holes on the well wall of the water collection well, the water collection well under this embodiment is more stable in structure. At the same time, the rectangular water collection well can be better combined with the circular drainage pipe.
[0125] Fig. 12A and 12BThe anti-blocking and permeable water collection well shown in the figure also has variations: for example, in the wavy cross-section of the rib 22 along the thickness direction of the water collection well wall, the amplitude thereof gradually decreases from the inside to the outside of the water collection well along the radial direction of the water collection well, and decreases to 0 on the outside of the water collection well.
[0126] like Fig. 12A and 12B The anti-blocking permeable water collection well shown in the figure has variations in shape, such as Fig.13A and 13B The anti-blocking permeable water collection well shown therein is circular, and the permeable wall body 21 is the annular well wall of the water collection well.
[0127] like Fig. 12A and 12B The anti-blocking permeable water collection well shown in the figure has other variations in shape, such as Fig.14A and 14B The anti-blocking permeable water collection well is a water collection box, which includes four side walls and an opening 24 surrounded by the side walls, wherein the three side walls of the water collection box include a plurality of ribs 22, and the three sides respectively form a permeable wall body 21 of the water collection box. Fig.14A and 14B The shape of the water collecting box shown is more suitable for multi-lane bridges. Fig.15A and 15B The anti-blocking permeable water collection well is an L-shaped water collection box, which is L-shaped when viewed from the side. A plurality of ribs 22 are arranged on three side walls of the water collection box, and the three side walls respectively form a permeable wall body 21 of the water collection box. The L-shaped water collection box is more suitable for use on urban elevated roads.
[0128] In some embodiments, the amplitude of the wavy cross-section of the plurality of ribs 22 in the water-permeable wall 21 of the water-permeable water-collecting well is nonlinear, so that the plurality of ribs 22 have mutually concealing wavy shapes on both the inner and outer sides of the water-collecting well.
[0129] In one embodiment, the anti-blocking and permeable water collection well is made of plastic material, and its molding method can include but is not limited to injection molding, compression molding and other suitable plastic molding processes. When the plastic water collection well is used in asphalt pavement, when the asphalt surface layer is damaged and needs to be milled and resurfaced, the plastic water collection well can be reused as part of the asphalt mixture. At the same time, degradable plastics can also be used in other fields that require drainage, making it more green and environmentally friendly.
[0130] In some embodiments, the plurality of ribs 22 of the anti-blocking permeable water collection well are connected by reinforcing ribs in the anti-blocking permeable water collection well, so that the water collection well will not be deformed when subjected to external force in the radial direction.
[0131] In some embodiments, at least a portion of the plurality of ribs 22 for preventing water from blocking and permeable water collection is provided with holes or grooves to form additional drainage channels, further improving drainage efficiency. In one or more embodiments, accessories such as steel wires, steel rods, plastic wires or plastic rods may be added to the holes or grooves to achieve the effect of increasing the strength of the water-permeable water collection well.
[0132] In some embodiments, a filter layer is further provided on the anti-blocking permeable water collection well. The filter layer allows drainage to enter the water collection well while preventing silt, debris, etc. from entering the interior thereof, thereby further preventing pipe blockage from occurring inside the anti-blocking permeable water collection well. In one or more embodiments, the filter layer may be, but is not limited to, composed of wrapping materials such as silk, cloth, membrane, and mixtures thereof, or may be a reverse filter layer.
[0133] In some embodiments, the plurality of ribs 22 may be made in the form of triangular, quadrilateral, double-wave, spiral or circular ribs.
[0134] In some embodiments, multiple ribs 22 are also provided with convex and / or concave patterns on the outer surface of the anti-blocking and permeable water collection well. The patterns can be used to increase the friction of the outer surface of the anti-blocking and permeable water collection well, prevent slipping and beautify the outer surface of the anti-blocking and permeable water collection well.
[0135] Figures 16 to 21 The invention shows various embodiments of the drainage device as an anti-blocking manhole cover, which is mainly used in places where a drainage manhole cover or cover plate is needed, and is used as an anti-blocking cover plate on a drainage ditch, a water collection well, a water leak hole, a swimming pool ditch, a bathroom drain ditch and a roadside ditch.
[0136] See also Fig.16 In one embodiment, the anti-blocking manhole cover is composed of a plurality of ribs 32, which extend radially from the center of the anti-blocking manhole cover to the periphery, and the plurality of ribs 32 constitute the water-permeable wall 31 of the anti-blocking manhole cover. The cross section of the ribs 32 on the surface of the anti-blocking manhole cover is wavy, and has alternating crests and troughs on either side of the manhole cover, and the crests of one rib and the troughs of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross section of the ribs 32 gradually decreases from one side of the anti-blocking manhole cover to the other side along the thickness direction of the anti-blocking manhole cover, and decreases to 0 on one side of the anti-blocking manhole cover. The gaps on the surface of the anti-blocking manhole cover are mutually blocked by the inner and outer surfaces of the plurality of ribs 32, thereby reducing the sundries outside the drainage ditch and items such as traffic cards and mobile phones from entering the manhole cover through the gaps, preventing the manhole cover from being blocked and preventing items from falling in. At the same time, the multiple waves on the surface of the manhole cover make it more stable and pressure-resistant, and both the wavy and non-wavy surfaces of the manhole cover can be used as the side facing the road, allowing users to choose which side to use as the surface according to specific scenarios.
[0137] like Fig.16 The anti-blocking manhole cover shown in the figure has some variations in the arrangement of the ribs 32, such as Fig.17 As shown, a plurality of ribs 32 extend between two opposite sides of the manhole cover. The anti-blocking manhole cover is composed of a plurality of ribs 32, and adjacent ribs 32 in the plurality of ribs 32 are alternately connected at both ends of the manhole cover. Fig.17 The anti-blocking manhole cover shown in the figure also has variations in appearance, such as Figures 18 to 20 As shown, the anti-blocking manhole cover can be rectangular, rectangular or L-shaped to meet the needs of various construction occasions. Fig. 20 The anti-blocking manhole cover is L-shaped. When applied to a bridge with a crash wall, one side of the mutually perpendicular cover body can fit the crash wall, and the other side can fit the road surface. The multiple ribs 32 of the anti-blocking manhole cover can be distributed in a suitable shape such as a grid shape, a honeycomb shape, etc. in the anti-blocking manhole cover, but are not limited to.
[0138] See also Fig.21 In one embodiment, the cross section of the rib 32 in the length extension direction of the anti-blocking manhole cover is wavy, and has alternating crests and troughs on either side of the manhole cover, and the crest of one rib and the trough of another rib in adjacent ribs are opposite to each other. The amplitude of the wavy cross section of the rib 32 gradually decreases from one side of the anti-blocking manhole cover to the other side along the thickness direction of the anti-blocking manhole cover, and decreases to 0 on one side of the anti-blocking manhole cover. This allows it to play the same role. Figures 16 to 20 The anti-blocking manhole cover shown in FIG. 1 has the same anti-blocking and anti-falling functions as the anti-blocking manhole cover shown in FIG. 2 , and any adjacent ribs among the plurality of ribs 32 are connected in an elastically expandable manner, so that the anti-blocking manhole cover structure is easy to stretch and bend, so that the anti-blocking manhole cover can better fit the construction direction and be applied to drainage devices of various shapes, preventing garbage and other debris from accumulating in the gap between the manhole cover and the road surface. In some embodiments, the plurality of ribs 32 of the multi-section manhole cover can be connected by welding, bonding or snapping.
[0139] In one embodiment, the anti-blocking manhole cover is made of plastic material, and its molding method can include but is not limited to injection molding, compression molding and other suitable plastic molding processes. When the manhole cover made of plastic material is used in asphalt pavement, when the asphalt surface layer is damaged and needs to be milled and resurfaced, the manhole cover can be reused as part of the asphalt mixture. At the same time, degradable plastics can also be used in other fields that require drainage, making it more green and environmentally friendly.
[0140] In some embodiments, the plurality of ribs 32 of the anti-blocking manhole cover are connected by reinforcing ribs in the anti-blocking manhole cover so that the anti-blocking manhole cover will not be deformed when subjected to external force in a radial direction.
[0141] In some embodiments, at least a portion of the plurality of ribs 22 of the anti-blocking manhole cover is provided with holes or grooves to form additional drainage channels, further improving drainage efficiency. In one or more embodiments, accessories such as steel wires, steel rods, plastic wires or plastic rods may be added to the holes or grooves to increase the strength of the anti-blocking manhole cover.
[0142] In some embodiments, a filter layer is further provided on the anti-blocking manhole cover. The filter layer allows drainage to enter the anti-blocking manhole cover while preventing mud, sand, and debris from entering the manhole cover, thereby further preventing pipe blockage inside the anti-blocking manhole cover. In one or more embodiments, the filter layer may be, but is not limited to, composed of wrapping materials such as silk, cloth, and membrane, and a mixture thereof, or may be a reverse filter layer.
[0143] In some embodiments, the plurality of ribs 32 may be made in the form of triangular, quadrilateral, double-wave, spiral or circular ribs.
[0144] In some embodiments, multiple ribs 32 are also provided with convex and / or concave patterns on the outer surface of the anti-blocking manhole cover, which can be used to increase the friction of the outer surface of the anti-blocking manhole cover, prevent slipping and beautify the outer surface of the anti-blocking manhole cover.
[0145] In some embodiments, the amplitude of the wavy cross-section of the plurality of ribs 32 in the anti-blocking manhole cover water-permeable wall 31 changes nonlinearly, so that the plurality of ribs 32 can have mutually concealing wavy shapes on both the inner and outer sides of the water collection well.
[0146] Although the present invention is disclosed as above with preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art may make possible changes and modifications without departing from the spirit and scope of the present invention. Therefore, any modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall fall within the protection scope defined by the claims of the present invention.
