Description

Technical Field

[0001] This invention relates to a prefabricated drainage component for municipal roads, and also to a construction method for the prefabricated drainage component for municipal roads. Background Technology

[0002] Water accumulation affects road safety, so road drainage systems are an important part of municipal road engineering. They are usually a comprehensive system engineering project. Road drainage systems are mainly used for drainage of the road surface, including pavement drainage. Through a certain slope design, the water on the road surface flows to the drainage wells set up on the roadside. Below the drainage wells are drainage ditches or drainage branch pipes, which then flow into the main pipe and finally into the river.

[0003] In the prior art, such as the Chinese patent with patent number CN202021290502.X, a rapid drainage system for municipal roads is disclosed. This open channel-like drainage method is common in the suburbs of cities. However, considering the aesthetics and image of the city, urban municipal roads usually use drainage wells to collect water. Drainage wells are usually set on the non-motorized vehicle lanes on the side of the road, and the drainage wells are set at certain intervals. Therefore, their drainage efficiency is lower than that of side ditches. The drainage wells are equipped with manhole covers. In the above technical solution, the manhole covers are equipped with drainage holes. The size of the drainage holes is usually limited to ensure the safety of pedestrians and traffic. Therefore, the drainage outlets usually adopt multiple elongated holes to achieve a balance between personnel safety and improved drainage efficiency. However, when encountering heavy rain and flooding, it is usually difficult to quickly drain the rapidly increasing water volume in a short period of time. Summary of the Invention

[0004] The purpose of this invention is to provide a prefabricated drainage component suitable for municipal roads with large water volumes. By using a combined panel and base frame for the drainage well cover, with the support strip of the base frame embedded in the drainage holes of the panel, the drainage hole width is reduced, facilitating pedestrian and vehicle passage. When rapid drainage is needed, the panel is moved to enlarge the drainage hole size, thereby accelerating drainage while preventing pedestrians and vehicles from falling in. | Another purpose of this invention is to provide a construction method for the above-mentioned drainage component.

[0005] Therefore, the present invention provides a prefabricated drainage component for municipal roads, including a drainage manhole cover. The drainage manhole cover includes a panel and a bottom frame. The panel includes a drainage hole, and the bottom frame is connected to a support strip. The support strip is parallel to the panel and is inserted into the drainage hole to cooperate with the panel to form a support structure. The panel or the support strip can move relative to each other to increase the drainage volume.

[0006] Furthermore, the panel is connected to the support column, and the support column is connected to the drive device. The drive device is used to drive the support column to move the panel downward when the water inflow of the drainage well cover reaches a predetermined amount.

[0007] Furthermore, the driving device is an electric lifting device, which includes a processor and a water immersion sensor. The water immersion sensor is located in the flow channel below the manhole cover. The flow channel includes an inlet, a first outlet, a second outlet, and a cavity. The water immersion sensor is located in an independent space, the bottom of which is connected to the cavity. The position of the water immersion sensor is between the first outlet and the second outlet.

[0008] Optionally, a spring is connected to the body of the support column, and the other end of the spring is connected to the bracket. The lower part of the support column is connected to the traction belt, and the traction belt is connected to the float in the flow channel through a fixed pulley. The flow channel includes an inlet, a first outlet and a second outlet, and the height of the first outlet is higher than that of the second outlet.

[0009] Furthermore, a limiting groove is provided in the middle of the two opposite sides of the drainage hole, and the support bar cooperates with the limiting groove.

[0010] Furthermore, the support strip is inverted concave.

[0011] Furthermore, the bottom frame is connected to the sleeve, which is located on the outer wall of the panel. The sleeve includes a lateral drain hole. When the support strip of the panel is embedded in the drain hole, the outer wall of the panel closes the drain hole. When the panel moves down, the drain hole opens.

[0012] Furthermore, a scraping assembly is provided between the sleeve and the panel. The longitudinal section of the side wall of the sleeve is inverted L-shaped. A ring is fixed on the side wall of the panel. A groove is provided on the upper part of the panel side wall. The scraping assembly is embedded in the groove and can move along the groove. The scraping assembly is connected to the ring by a spring. The scraping assembly includes an arc-shaped scraper blade. A guide groove is provided on the panel. The guide groove cooperates with the arc-shaped scraper blade to guide the debris scraped by the scraping assembly into the flow channel.

[0013] This invention also includes a construction method for prefabricated drainage components for municipal roads, comprising the following steps: S1: Sleeve the scraper assembly onto the ring on the outer wall of the panel. Install a spring between the bottom of the scraper assembly and the ring. After installation, when the spring is in its natural state, the bottom of the arc of the arc scraper is flush with the upper surface of the panel. When the upper surface of the arc scraper is flush with the upper surface of the panel, the upper end of the guide groove is aligned with the bottom of the arc of the scraper. S2: Fit the panel and support column into the sleeve body, connect the fixing strip to the upper part of the sleeve body, and embed the support strip into the limiting groove; S3: Install the immersion sensor into the housing, connect the first and second water outlets of the housing to the drain branch pipe, connect the wires of the immersion sensor to the control chip of the motor, and connect the water inlet of the housing to the flow channel at the bottom of the bottom frame. S4: Install the motor and lifting device in the internal space of the base, connect the support column to the lifting device, fix the base at the bottom of the base frame, and fix the base to the foundation of the drainage well or the pre-embedded components by concrete or bolts.

[0014] The advantages of this invention over the prior art are as follows: (1) The drainage component of the present invention adopts a combined panel and bottom frame. The support strip of the bottom frame is set in the drainage hole of the panel. After the bottom frame and the panel are combined, the support strip is flush with the upper surface of the panel, so that the width of the drainage hole is small and plays a supporting role. It can effectively prevent pedestrians or vehicles from falling into the excessively wide drainage hole. When rapid drainage is required, the panel is moved longitudinally to make the size of the drainage hole larger, thereby accelerating drainage. After the movement, the support strip only reduces the height and increases the size of the drainage hole. It can still play a supporting role and reduce the impact on road safety.

[0015] (2) In a specific embodiment of the present invention, the panel is made flush with the ground by the compression of the spring. When pedestrians or vehicles pass by, the spring contracts, causing the panel to move down to a certain extent, so that the debris blocking the drain hole loses support or the friction decreases and falls down, thus avoiding the blockage of the drain hole. Even if the drain hole is blocked, when the panel moves down under the action of the driving device, one side of the debris loses the support of the support strip and will be quickly cleared under the impact of the water flow.

[0016] (3) Road surfaces usually contain a certain amount of mud and sand. Using a lifting mechanism to increase drainage volume, an unavoidable problem is that some mud and sand particles easily enter the side wall of the panel, causing the panel to deviate and increasing friction, making movement difficult. In a specific embodiment of the present invention, a smooth steel plate is used to make the mating wall of the panel and the sleeve, and a mud scraping component is set up to scrape away the mud and sand particles during the panel lifting process, thereby avoiding or reducing the impact of this problem.

Detailed Implementation

[0019] To further illustrate the technical means and effects of the present invention in achieving its intended purpose, the following detailed description of the specific implementation methods, structures, features, and effects of the present invention, in conjunction with the accompanying drawings and preferred embodiments, is provided below.

[0020] Reference Figures 1 to 8 As shown, a prefabricated drainage component for municipal roads according to the present invention includes a drainage manhole cover 2. The drainage manhole cover 2 includes a panel 201 and a base frame 204. The panel 201 includes a plurality of vertically arranged drainage holes 202. The base frame 204 is provided with support bars 205 corresponding to the drainage holes 202. The support bars 205 are parallel to the panel 201 and are inserted into the drainage holes 202 to cooperate with the panel 201. The upper surface of the support bars 205 is flush with or nearly flush with the upper surface of the panel 201 to form a support structure. The panel 201 moves up and down, increasing the distance between the panel 201 and the support bars 205, thereby increasing the drainage volume. (Refer to...) Figures 1 to 7As shown, in the first embodiment of the present invention, the panel 201 is a flat perforated structure made of materials such as carbon steel and cast iron. The drainage holes 202 are parallel to the middle of both sides of the road surface and have limiting grooves 203. The bottom frame 204 includes a sleeve 206 formed by upwardly extending walls on all four sides. The bottom surface of the bottom frame 204 has a frame formed by welding multiple steel members, with a permeable structure in the middle. A concave support strip 205 is welded to the bottom frame 204 at the position corresponding to the limiting groove 203. When the panel 201 moves downwards, the support strip... The space at the bottom of panel 205 can increase the size of the drain hole. Several support columns 3 are connected to the lower surface of panel 201. The support columns 3 are connected to an electric lifting device 4 located inside the base 5. The electric lifting device 4 includes a motor, processor, control circuit, and a water immersion sensor 13 for determining the water inlet volume. The water immersion sensor 13 is located in the housing 6. The housing 6 is divided into cavities forming flow channels, a transition section 604 connected to the cavities, and an independent space for the water immersion sensor 13. The flow channels of the housing 6 also include… The system includes an inlet 601, a first outlet 602, and a second outlet 603. The water immersion sensor 13 is positioned between the first outlet 602 and the second outlet 603. The transition section 604 is separated from the flow channel and the water immersion sensor by a perforated partition to prevent accidental water immersion of the water immersion sensor from causing unintended operation. The inlet 601 is connected to the channel below the bottom frame 204, allowing water entering through the drain hole 202 to enter the flow channel through the inlet 601 and be discharged from the first outlet 602. The size design of the water outlet 602 makes its maximum flow rate less than the maximum flow rate of the drain hole 202 by a predetermined value. The maximum flow rate of the first water outlet 602 is a threshold. When the inlet flow rate is greater than the threshold, the water level in the flow channel gradually rises and flows to the immersion sensor 13 through the transition section 604. The immersion sensor 13 transmits a signal to the processor and controls the motor to make the panel 201 drop, further increasing the drainage volume. Water is discharged from the second water outlet 603 and the first water outlet 602 to the drainage ditch or drainage branch pipe 14.

[0021] In the above embodiments, reference is made to Figure 4 and Figure 5 As shown, it may also include a bar screen filter device 7, which is shaped as an inclined plane or a herringbone. A sludge collection tank may be set at one or both ends of the bar screen filter device 7. The inclined bar screen filter device 7 washes the debris along the bar screen into the sludge collection tank under the flushing of water. A filter screen may be set in the direction of the sludge collection tank facing the flow channel. The water after filtering the debris continues to flow into the flow channel. An L-shaped storage tank 8 is set in the sludge collection tank, and an openable cover may be set on the top for removing debris.

[0022] In the above embodiments, reference is made to Figure 9As shown, a scraping assembly can be provided between the panel 201 and the sleeve 206. A ring 207 is integrally formed on the bottom of the outer wall of the panel 201. A dovetail-shaped groove (not shown) is provided on the upper side wall of the panel 207. The scraping assembly is located in the groove and can move along it. The bottom of the scraping assembly is connected to the upper surface of the ring 207 by a spring 10. An elastic baffle tube can be provided between the spring 10 and the scraper blade 208 to prevent sand and gravel from entering the spring. The scraping assembly includes an arc-shaped scraper blade 208, which is set tightly against the inner wall of the sleeve 206. The panel 201 has an oblique... The guide groove 209, when the spring 10 is in its natural state, has the bottom of the arc of the arc-shaped scraper 208 flush with the upper surface of the panel 201. When the upper surface of the arc-shaped scraper 208 is flush with the upper surface of the panel 201, the upper end of the guide groove 209 is aligned with the bottom of the arc of the scraper 208. The guide groove 209 and the arc-shaped scraper 208 work together to guide the debris scraped by the scraper assembly into the flow channel. The upper part of the sleeve 206 can be fixed with a fixing strip 210 by bolts, so that the longitudinal section of the side wall of the sleeve 206 is generally inverted L-shaped. The fixing strip 210 restricts the scraper 208 from extending out of the road surface and affecting safety. In this embodiment, the interior of the sleeve 206 and the outer wall of the panel 201 are made of smooth steel plate, and a scraper assembly can also be provided at the lower part of the panel 201.

[0023] In the above embodiments, reference is made to Figure 3 As shown, the side wall of the sleeve 206 of the bottom frame also includes a lateral drain 9. When the panel 201 is not lowered, i.e., when the support strip 205 of the panel 201 is embedded in the drain hole 202, the lateral drain 9 can be closed by the side wall of the panel 201 to prevent debris from entering and clogging. When the panel 201 is lowered, the lateral drain 9 can be opened to increase the drainage volume. In addition, the lateral drain 9 can be connected to a drain pipe or drain ditch on its own. The drain pipe or drain ditch can be connected to the main drain pipe to solve the problem of being limited by the maximum flow of the drain branch pipe when the drainage volume is too large.

[0024] The second embodiment of the present invention is basically the same as the first embodiment, except that the driving device of the second embodiment is different from that of the first embodiment. In the second embodiment, a spring 10 is connected to the column of the support column 3 in the internal space of the box. The other end of the spring 10 is fixed to the bracket or partition. The lower part of the support column 3 is connected to the traction belt. The traction belt is connected to the float 12 in the flow channel through the fixed pulley 11. The flow channel includes an inlet 601, a first outlet 602 and a second outlet 603. The height of the first outlet 602 is higher than that of the second outlet 603. In the second embodiment, when the water inflow is greater than the threshold, the water level in the flow channel rises, thereby driving the float 12 to rise. The float drives the panel 201 to fall. In the second embodiment, the panel can be raised or lowered when the sum of the buoyancy of the float and the weight of the panel is greater than the elastic force of the spring.

[0025] The present invention also includes a construction method for a prefabricated drainage component for municipal roads according to Embodiment 1 above, comprising the following steps: S1: The scraper assembly is fitted onto the ring 207 on the outer wall of the panel 201. A spring 10 is installed between the bottom of the scraper assembly and the ring 207. After installation, when the spring 10 is in its natural state, the bottom of the arc of the arc scraper 208 is flush with the upper surface of the panel 201. When the upper surface of the arc scraper 208 is flush with the upper surface of the panel 201, the upper end of the guide groove 209 is aligned with the bottom of the arc of the scraper 208. S2: Fit the panel 201 and the support column 3 into the sleeve 206, connect the fixing strip 210 to the upper part of the sleeve 206, and embed the support strip 205 into the limiting groove 203; S3: Install the immersion sensor 13 into the housing 6, and connect the first water outlet 602 and the second water outlet 603 of the housing 6 into the drain branch pipe 14. Connect the wire of the immersion sensor 13 to the control chip of the motor, and connect the water inlet 601 of the housing 6 to the flow channel at the bottom of the bottom frame 204. S4: Install the motor and lifting device in the internal space of the base 5, and connect the support column 3 to the lifting device. Fix the base 5 at the bottom of the base frame 204. The base 5 is fixed to the foundation or pre-embedded components of the drainage well 1 by concrete or bolts.
