Description

Urban integrated pipe gallery drainage system and construction methods Technical Field

[0001] This invention relates to the field of urban drainage engineering technology. More specifically, this invention relates to an urban integrated pipe gallery drainage device and its construction method. Background Technology

[0002] Urban integrated utility tunnels refer to public tunnels underground in cities used for the centralized laying of municipal pipelines such as electricity, communications, broadcasting and television, water supply, drainage, heating, and gas. Integrated utility tunnels are widely used to solve the problem of frequent road excavation due to pipeline maintenance or expansion. Proper drainage is essential within the tunnel to ensure the safety of the pipelines. This is achieved by installing drainage pipes inside the tunnel, with corresponding sludge collection wells to remove waste from the drainage. However, existing drainage systems for utility tunnels often suffer from difficulties in removing the accumulated waste from these wells, requiring specialized dredging equipment, which is costly. Furthermore, on slightly sloping drainage pipes, silt and sand easily accumulate at the bottom during drainage. Existing drainage systems lack the ability to dredge the drainage pipes, leading to an increasing accumulation of debris, reduced water flow, and in severe cases, blockages that prevent proper drainage and compromise the safety of other pipelines within the tunnel. Summary of the Invention

[0040] As shown in Figures 1-5, the present invention provides a drainage device for an urban integrated utility tunnel, comprising:

[0041] Drainage pipe 2 is located in pipe gallery 1;

[0042] Multiple sludge collection mechanisms are spaced apart along the length of drain pipe 2, and each sludge collection mechanism includes:

[0043] The first sewage collection pipe has a U-shaped structure, and its two vertical edges are arranged radially at intervals along the drain pipe 2.

[0044] The horizontal side 33 of the first sewage collection pipe is perpendicular to the drain pipe 2 and is located at the bottom of the pipe gallery 1. The free end of one of the vertical sides of the first sewage collection pipe is connected to the bottom of the drain pipe 2, and the free end of the other vertical side extends upward to the top of the pipe gallery 1.

[0045] Qi Ping;

[0046] The second sewage pipe 34 is coaxially arranged with one of the vertical sides of the first sewage pipe. The lower end of the second sewage pipe 34 is connected to the top of the drain pipe 2, and the upper end extends upward to be flush with the top of the pipe gallery 1.

[0047] The sewage collection net 35 is a flexible net bag installed inside the first sewage collection pipe. The open end of the sewage collection net 35 is located inside one of the vertical sides of the first sewage collection pipe. The open end of the sewage collection net 35 is provided with a first support ring 351, on which a drawstring bag 353 that can be sealed by pulling a drawstring 354 is fitted.

[0048] The first rope 36 has one end connected to the first support ring 351 of the sewage collection net 35, and the other end extends vertically upward through the drain pipe 2 and the second sewage collection pipe 34 to the top of the pipe gallery 1; the drawstring 354 of the drawstring bag 353 is slidably connected to the first rope 36.

[0049] The second rope 37 has one end connected to the tail end of the sewage collection net 35, and the other end extends vertically upward through the first sewage collection pipe to the top of the pipe gallery 1.

[0050] In the above technical solution, the present invention provides an urban integrated pipe gallery drainage device, which includes a drainage pipe 2 (a slightly sloped or horizontal section of the drainage pipe 2) installed in the pipe gallery 1, and multiple sewage collection mechanisms arranged at intervals along the water flow direction. Each sewage collection mechanism includes a U-shaped first sewage collection pipe, a vertical straight-line second sewage collection pipe 34, a sewage collection net 35 installed in the first sewage collection pipe, and a first rope 36 and a second rope 37 respectively installed at both ends of the sewage collection net 35. The two vertical sides of the first sewage collection pipe are of unequal length, as shown in Figures 2-3. The first sewage collection pipe and the drainage pipe 2... The length of one vertical side connected to the bottom of the first sewage collection pipe is less than the length of the other vertical side 32 of the first sewage collection pipe. The horizontal side 33 of the first sewage collection pipe has an arc-shaped structure. Preferably, the bottom of the horizontal side 33 is provided with a seepage hole, which is connected to the drain pipe 2 through a water guide pipe. One vertical side 31 of the first sewage collection pipe passes through the side wall (bottom) of the drain pipe 2 and connects to the inside of the drain pipe 2, thereby connecting the drain pipe 2 and the first sewage collection pipe. The second sewage collection pipe 34 is located at the top of the drain pipe 2 and is coaxially arranged with the first sewage collection pipe. The lower end of the second sewage collection pipe 34 passes through the side wall (top) of the drain pipe 2 and connects to the drain pipe 2. Drainage pipe 2 is connected, and a sewage collection net 35 is installed inside the first sewage collection pipe to collect silt, sand, and other debris. The sewage collection net 35 is a flexible net, such as a long, narrow shrimp trap or fish trap. The open end of the sewage collection net 35 is located inside the first sewage collection pipe and is close to drainage pipe 2, facilitating the entry of silt, sand, and other debris into the sewage collection net 35. The two ends of the sewage collection net 35 are respectively connected to a first rope 36 and a second rope 37. The upper end of the first rope 36 extends through drainage pipe 2 and the second sewage collection pipe 34 to the top of the pipe gallery 1, and the upper end of the second rope 37 extends through the first sewage collection pipe... The other vertical side 32 of the pipe extends above the pipe gallery 1; by pulling the first rope 36 / second rope 37 outside the pipe gallery 1, the sewage collection net 35 is moved inside the first sewage collection pipe; furthermore, a drawstring bag 353 is provided at the open end of the sewage collection net 35, and the open end of the drawstring bag 353 can be closed by pulling the drawstring 354, thereby sealing the open end of the sewage collection net 35; the drawstring 354 of the drawstring bag 353 extends upward and slides to connect with the first rope 36, and the opening of the drawstring bag 353 can be closed by pulling the drawstring bag 353 relative to the first rope 36.

[0051] The present invention provides a sludge collection net 35 for collecting sludge, which is installed inside a first sludge collection pipe. Silt and sand from the drain pipe 2 are deposited within the sludge collection net 35 inside the first sludge collection pipe. Both ends of the sludge collection net 35 are connected to a first rope 36 and a second rope 37, respectively. When sludge removal is required, firstly, the pull rope 354 is pulled upwards relative to the first rope 36, thereby closing the opening of the pull rope bag 353 to prevent sludge from falling out of the opening of the sludge collection net 35 during removal. Then, the second rope 37 is pulled upwards to move the sludge collection net 35 to the other vertical side 32 of the first sludge collection pipe, and the pulling continues upwards until the sludge is removed from the other vertical side of the first sludge collection pipe. The sludge collection net 35 is removed from the top of the straight edge 32, and the sludge inside the sludge collection net 35 is cleaned. No professional sludge cleaning equipment is required, and the sludge cleaning efficiency is high and the cost is low. After the sludge collection net 35 is cleaned, the draw rope 354 is moved relative to the first rope body 36, so that the opening of the draw rope bag 353 is opened. Then, it is put back into the first sludge collection pipe through the top of the other vertical edge 32. By pulling the first rope body 36 upward, the sludge collection net 35 is pulled to its open end and moved into one of the vertical edges 31 of the first sludge collection pipe. The drainage device of the present invention can conveniently and quickly clean up the deposited dirt, while not affecting the normal drainage of the drainage pipe 2.

[0052] Preferably, the first support ring 351 and the first rope 36, the tail end of the sewage collection net 35 (the tail end is closed, and the first support ring 351 can also be provided) and the second rope 37 are all detachably connected. After the sewage collection net 35 is pulled out from the other vertical side 32 of the first sewage collection pipe, one end of the first rope 36 is pulled to the top of the other vertical side 32 of the first sewage collection pipe. The operator can detach both ends of the sewage collection net 35 from the first rope 36 and the second rope 37 outside the pipe gallery 1, so as to facilitate the movement of the sewage collection net 35 into the water tank for cleaning.

[0053] Preferably, after the sewage collection net 35 moves into place in the first sewage collection pipe, the first support ring 351 at the open end of the sewage collection net 35 abuts against the bottom outer wall of the drain pipe 2, that is, the open end of the sewage collection net 35 can no longer move upward, so that the draw rope 354 can be pulled upward relative to the first rope 36, thereby closing the open end of the draw rope bag 353.

[0054] In another technical solution, the urban integrated pipe gallery drainage device has an iron boss 352 on the top surface of the first support ring 351. The drawstring bag 353 is open at both ends, with one end fixedly sleeved on the first support ring 351 and the other end equipped with multiple magnets 356. When the sewage collection net 35 is used to collect sewage, the open end of the drawstring bag 353 is opened, and the magnets 356 are attracted to the boss 352, which facilitates positioning of the open state of the drawstring bag 353. When the sewage collection net 35 needs to be removed, the drawstring 354 is pulled upward relative to the first rope 36 to seal the other end of the drawstring bag 353. The sliding connection between the drawstring 354 and the first rope 36 is specifically as follows: a collar 361 is fixedly provided near one end of the first rope 36, and a slider 362 is slidably provided on the first rope 36, located above the collar 361; the two free ends of the drawstring 354 extend upward through the collar 361 and connect with the slider 362. The bag body of the drawstring bag 353 can be made of elastic material. Preferably, after the slider 362 moves into position, it is fixed to the first rope 36. Specifically, a metal plate can be provided on the slider 362. When it is necessary to move the slider 362, the metal plate is pried open to a position where it does not interfere with the first rope 36, and the slider 362 can move relative to the first rope 36. After the slider 362 is moved into position, the metal plate is squeezed so that the metal plate tightly covers the first rope 36, thereby temporarily fixing the slider 362 to the first rope 36.

[0055] In another technical solution, the urban integrated pipe gallery drainage device includes a sewage collection net 35 with multiple second support rings 357 spaced apart inside. The second support rings 357 support the middle of the sewage collection net 35, facilitating faster collection of waste within the net. Both the first support ring 351 and the second support ring 357 have ball bearings on their outer circumferential walls. The sewage collection net 35 also includes a hanging ring 363 located in the middle of the first support ring 351. The hanging ring 363 and the first support ring 351 are concentric. Multiple fixing rods are spaced apart circumferentially between the hanging ring 363 and the first support ring 351. Each fixing rod is horizontally positioned and its two ends are connected to the hanging ring 363 and the first support ring 351, respectively. One end of the first rope 36 is connected to the hanging ring 363.

[0056] In another technical solution, the urban integrated pipe gallery drainage device further includes a rope drum 38 for each sewage collection mechanism, which is horizontally rotatably mounted on the top of the pipe gallery 1 via a support. The other ends of the first rope 36 and the second rope 37 are both wound around the rope drum 38, and the winding directions of the first rope 36 and the second rope 37 are the same. A rope drum 38 is installed at the top of the pipe gallery 1. The first rope 36 and the second rope 37 are both wound around the rope drum 38. The rotation of the rope drum 38 can be manual or driven by a motor. The first rope 36 and the second rope 37 are initially tensioned. When it is necessary to remove the sewage collection net 35 from the first sewage collection pipe, the rope drum 38 is rotated in the first direction, tightening the second rope 37. The first rope 36 rotates out of the rope drum 38, and the sewage collection net 35 is gradually pulled into the other vertical side 32 of the first sewage collection pipe, eventually moving upwards from the top of the other vertical side 32. When it is necessary to put the sewage collection net 35 back into the first sewage collection pipe, both ends of the sewage collection net 35 are... The first rope 36 and the second rope 37 are connected, and the two ends of the draw rope 354 are connected again to the collar 361 and the slider 362 (when the sludge collection net 35 is taken out, one end of the first rope 36, along with the slider 362, is pulled to the top of the other vertical side 32 of the first sludge collection pipe. During sludge removal, the first rope 36 and the second rope 37 are separated from the sludge collection net, the draw rope 354 is separated from the collar 361 and the slider 362, and the opening of the draw rope bag 353 is open). The rope drum 38 is rotated around the second direction (opposite to the first direction) to tighten the first rope 36, and the second rope 37 is rotated from the rope drum 38. The sludge collection net 35 is gradually pulled into the first sludge collection pipe (as shown in Figures 2-3). Preferably, a fixed pulley 39 corresponding to the first rope 36 and the second rope 37 can be provided. Specifically, it can be provided at the top of the second sewage collection pipe 34 and the top of the other vertical side 32 of the first sewage collection pipe. This can tension the first rope 36 and the second rope 37, making it easier to turn from a vertical state and wrap around the rope drum 38.

[0057] In another technical solution, the urban integrated pipe gallery drainage device further includes multiple dredging mechanisms, with each sewage collection mechanism corresponding to one dredging mechanism, and each dredging mechanism comprising:

[0058] A rotating shaft 41 is coaxially rotatable inside a drain pipe 2 via a bearing assembly; multiple blades 411 with different angles are spaced along the circumferential direction on each rotating shaft 41, and the multiple blades 411 are all located between two scraper blades 42.

[0059] Two scraper blades 42 are connected to the rotating shaft 41 via a connecting rod. The two scraper blades 42 are spaced apart along the length of the drain pipe 2 and are located on both sides of the rotating shaft 41. Each scraper blade 42 is a strip structure parallel to the drain pipe 2. The side of the scraper blade 42 closest to the inner wall of the drain pipe 2 is in close contact with the inner wall of the drain pipe 2.

[0060] The first bevel gear 43 is coaxially sleeved on the rotating shaft 41; the first bevel gear 43 is located near the second sewage collection pipe 34;

[0061] The first telescopic rod 44 is located inside the second sewage collection pipe 34 and parallel to the drain pipe 2. One end of the first telescopic rod 44 is connected to the inner wall of the second sewage collection pipe 34, and the other end is provided with a bearing sleeve 45.

[0062] Sleeve 46 is vertically installed inside the second sewage collection pipe 34. The lower end of sleeve 46 is fitted with a second bevel gear 461 that can mesh with the first bevel gear 43, and the upper end extends upward through the bearing sleeve 45.

[0063] Cylinder 47 is slidably disposed on the top of pipe gallery 1 along the length of drain pipe 2, and piston rod of cylinder 47 extends vertically upward.

[0064] The lower end of one vertical side of the L-shaped movable rod 48 is coaxially inserted into the sleeve 46 and connected to the inner wall of the sleeve 46 through a vertically arranged spring 481. The upper end extends vertically upward through the second sewage collection pipe 34 and extends above the pipe gallery 1. The lower outer wall of the L-shaped movable rod 48 is helically connected to the inner wall of the sleeve 46. The other vertical side of the movable rod is connected to the free end of the piston rod of the cylinder 47.

[0065] The second telescopic rod 49 is located inside the second sewage collection pipe 34 and parallel to the first telescopic rod 44. The second telescopic rod 49 is located above the first telescopic rod 44. One end of the second telescopic rod 49 is slidably connected to the inner wall of the second sewage collection pipe 34 in the vertical direction, and the other end is connected to the upper part of a vertical side of the L-shaped movable rod 48.

[0066] In the above technical solution, the present invention further provides a sludge removal mechanism for scraping and cleaning the sediment on the inner wall of the drain pipe 2. This mechanism includes a rotating shaft 41 coaxially rotatably disposed within the drain pipe 2; two scraper blades 42 connected to the rotating shaft 41 via a connecting rod; a first bevel gear 43 coaxially fixed and rotatably sleeved on the rotating shaft 41; a sleeve 46 disposed within the second collection pipe 34 and rotatable and horizontally movable via a first telescopic rod 44; a movable rod 48 with its lower part helically rotatably connected to the sleeve 46; and a cylinder 47 driving the movable rod 48 to move up and down. A bearing sleeve 45 is provided on the first telescopic rod 44, the upper end of the sleeve 46 passes through the bearing sleeve 45, and the sleeve 46 is rotatably connected to the end of the first telescopic rod 44 via the bearing sleeve 45. A telescopic rod 44 can drive the sleeve 46 to move horizontally within the second sewage pipe 34 through telescopic movement. At the same time, the first telescopic rod 44 will not interfere with the rotation of the sleeve 46 around its own axis. The second telescopic rod 49 is slidably connected to the inner wall of the second sewage pipe 34 in the vertical direction. The second telescopic rod 49 can move up and down relative to the second sewage pipe 34. The telescopic movement of the second telescopic rod 49 can drive the movable rod 48 to move horizontally within the second sewage pipe 34. At the same time, the piston rod of the cylinder 47 retracts, which can drive the movable rod 48 to move up and down. The up and down movement of the movable rod 48 can drive the sleeve 46 to rotate around its own axis, thereby driving the second bevel gear 461 to rotate, which in turn drives the first bevel gear 43, the rotating shaft 41, and the scraper 42 to rotate, so that the scraper 42 can scrape and clean the inner wall of the drain pipe 2.

[0067] As shown in Figure 1 on the right, the sludge-clearing mechanism, when it is necessary to clean the inner wall of the drain pipe 2, moves the cylinder 47 to the left, causing the movable rod 48, sleeve 46, and second bevel gear 461 to move to the left as a whole (the first telescopic rod 44 and the second telescopic rod 49 retract), so that the second bevel gear 461 meshes with the first bevel gear 43. Then, the cylinder 47 is activated, driving the piston rod to move up and down, which in turn drives the movable rod 48 to move up and down. The sleeve 46 will not move up and down due to the limitation of the first telescopic rod 44. The inner wall of the cylinder 46 and the outer wall of the movable rod 48 are connected by a spiral rotation. Therefore, the up and down movement of the movable rod 48 will drive the sleeve 46 to rotate around its own axis. The rotation of the sleeve 46 will drive the second bevel gear 461 to rotate, which in turn will drive the first bevel gear 43, the rotating shaft 41, and the two scraper blades 42 to rotate. The scraper blades 42 rotate relative to the drain pipe 2 to scrape and clean the silt adhering to the inner wall of the drain pipe 2. The scraping force is large and the scraping coverage area is large, so the inner wall of the drain pipe 2 can be cleaned more thoroughly.

[0068] As shown in Figure 1 on the left, when dredging is not required, the cylinder 47 is moved to the right, which drives the movable rod 48, the sleeve 46, and the second bevel gear 461 (the first telescopic rod 44 and the second telescopic rod 49 are extended) to move to the right as a whole. The second bevel gear 461 moves to a position where it does not interfere with the first bevel gear 43.

[0069] A blade 411 is installed on the rotating shaft 41. When the water flow is relatively large, the blade 411 can be driven to rotate by the water flow power, which in turn drives the rotating shaft 41 to rotate. This causes the scraper 42 to scrape the inner wall of the drain pipe 2, cleaning the sediment on the inner wall of the drain pipe 2. Automatic sludge removal can be achieved. Combined with manual intervention sludge removal by moving the cylinder 47, the efficiency of cleaning sediment on the inner wall of the drain pipe 2 can be improved.

[0070] In another technical solution, the urban integrated pipe gallery drainage device has a corresponding cover for each sewage collection mechanism. The top of the second sewage collection pipe 34, the top of the other vertical side of the first sewage collection pipe, the cylinder 47, and the rope winding drum 38 are all covered within the cover. The cover protects the top of the second sewage collection pipe 34, the top of the other vertical side 32 of the first sewage collection pipe, the cylinder 47, and the rope winding drum 38, preventing external debris from falling into the first sewage collection pipe and providing protection for the cylinder 47 and the rope winding drum 38.

[0071] The present invention also provides a construction method for a drainage device in an urban integrated utility tunnel, wherein the above-mentioned drainage device is installed inside the urban integrated utility tunnel 1, specifically as follows:

[0072] Step 1: Install multiple U-shaped first sewage collection pipes at intervals inside the pipe gallery 1, and coaxially install a second sewage collection pipe 34 above one of the vertical sides 31 of each first sewage collection pipe; during the factory prefabrication process, install a first telescopic rod 44, a second telescopic rod 49, a sleeve 46, a second bevel gear 461, and a movable rod 48 inside each second sewage collection pipe 34. After the second sewage collection pipe 34 is installed in place, connect the horizontal part of the movable rod 48 to the top of the piston rod of the cylinder 47.

[0073] Step 2: Make multiple pairs of perforations at intervals along the length of the drain pipe 2, with each pair of perforations located at the top and bottom of the drain pipe 2 respectively; pre-install the rotating shaft 41, the scraper 42 and the first bevel gear 43 inside the drain pipe 2; install the drain pipe 2 inside the pipe gallery 1, and seal the top perforation of the drain pipe 2 to the lower edge of the second sewage collection pipe 34 (which can be connected by electric welding), and seal the bottom perforation to the free end edge of one of the vertical sides of the first sewage collection pipe.

[0074] Step 3: Move one end of the first rope 36 downwards through the top of the second collection pipe 34, through the drain pipe 2, and via one vertical side 31, the horizontal side 33, and the other vertical side 32 of the first collection pipe, until it reaches above the other vertical side 32 of the first collection pipe. Connect the open end of the collection net 35 to one end of the first rope 36, and open the drawstring bag 353 at the open end of the collection net 35. Pass the two free ends of the drawstring 354 through the loops 361 on the first rope 36 and connect them to the slider 362 on the first rope 36. Connect the tail end of the collection net 35 to the second rope 37. Then, insert the collection net 35 into the first collection pipe through the top of the other straight side of the first collection pipe. Finally, pull the other end of the first rope 36 from the top of the second collection pipe 34 to pull the collection net 35 into the first collection pipe. The number of devices and processing scale described here are for the purpose of simplifying the description of the invention. Applications, modifications and variations of the present invention will be readily apparent to those skilled in the art.

[0075] Although embodiments of the present invention have been disclosed above, they are not limited to the applications listed in the specification and embodiments. They can be applied to various fields suitable for the present invention. For those skilled in the art, other modifications can be easily made. Therefore, without departing from the general concept defined by the claims and their equivalents, the present invention is not limited to the specific details and illustrations shown and described herein.
