Description

Technical Field

[0001] The utility model belongs to the technical field of pipe network drainage, and in particular relates to a pipe network diversion drainage system. Background Art

[0002] The existing pipe network drainage system uses the jacking process to build pipes. Pipe jacking construction is a trenchless construction method, which is a pipe burial construction technology with no excavation or less excavation. Pipe jacking construction is to use the jacking force generated by the jacking equipment in the working pit to overcome the friction between the pipe and the surrounding soil, push the pipe into the soil according to the designed slope, and transport the soil away. After one section of the pipe is pushed into the soil layer, the second section of the pipe is pushed in. The principle is to use the thrust of the main jacking cylinder and the pipeline room, relay room, etc. to push the tool pipe or tunnel boring machine from the working pit through the soil layer and lift it into the receiving pit. The pipeline is buried between the two pits following the tool pipe or tunnel boring machine. Technological process: measuring and setting out the center of the well → installing equipment and tracks → lifting the pipeline into place → manual excavation and unearthing → starting the machine for jacking → measuring, controlling and correcting deviations → assembling the pipeline → jacking the pipeline → excavating, unearthing and jacking the second section of the pipeline… → the jacking force is close to the allowable stress → placing the relay room (if necessary) → continuing jacking as above → … jacking into place → exiting the hole and removing the tool pipe → re-measurement of the entire line → completion of jacking → water-tightness test.

[0003] Inspection wells are an important part of the city's underground pipeline system within the pipeline network. They provide an entrance to the underground pipeline system, which is convenient for workers to conduct regular inspections and maintenance. They are generally located at pipeline intersections, bends, places where pipe diameters or slopes change, and at regular intervals on straight pipe sections to facilitate regular inspections of ancillary structures.

[0004] At present, there is a rainwater and sewage inspection well on the market with the publication number CN113502898A, which includes an inspection well body, a rainwater and sewage collection well, a diversion mechanism, an anti-fall net, and an in-place prompt mechanism. The present invention is aimed at the complex environmental conditions in cities and towns, and has invented an inspection well for the diversion of rainwater and sewage. Compared with the traditional simple sewage inspection well and rainwater inspection well, it has a wider range of applications. Under the complex environmental conditions in cities and towns, such as seafood markets and farmers' markets, most of them are concentrated pollution-producing areas. Relying on the traditional simple rainwater and sewage diversion pipeline system, it is impossible to effectively solve the problem of discharging sewage into the rainwater pipe, nor can it solve the problem of rainwater and sewage diversion. The rainwater and sewage diversion inspection well of the invention effectively solves the problem of rainwater and sewage diversion discharge under complex environmental conditions such as seafood markets and farmers' markets, and is of great significance.

[0005] But there is also a problem: the inspection well of this scheme has poor air permeability, which can easily cause toxic gases to accumulate in the well, making it easy for workers to be poisoned when entering, but the air holes are too large, which can easily cause pedestrians to drop things in. Utility Model Content

[0006] The utility model provides a pipe network diversion drainage system, which is used to solve the problems of ventilation of inspection wells and preventing objects from falling into the wells.

[0007] The present invention provides a pipe network diversion drainage system, including a rainwater drainage pipe: the rainwater drainage pipe is used to transport rainwater; a sewage drainage pipe: the sewage drainage pipe is used to transport sewage; an inspection well: a plurality of inspection wells are provided, and the inspection wells are respectively arranged at the rainwater drainage pipe and the sewage drainage pipe, the inspection well includes a well cover, a well wall and a well seat, the well seat is fixedly connected to the well wall, and the well cover cooperates with the well seat; a rainwater collection well: the rainwater collection well is used to collect rainwater, and the rainwater collection well is connected to the rainwater drainage pipe; a factory sewage location: the factory sewage is connected to the sewage drainage pipe, a treatment plant: the treatment plant is connected to the sewage drainage pipe, a plurality of air holes are provided on the well cover, and a filter plate for filtering impurities is provided on the air holes.

[0008] The principle of this scheme is: this scheme adopts rainwater and sewage diversion drainage. When it rains, rainwater will flow into the rainwater collection well, and the rainwater collection well will discharge rainwater into the rainwater drainage pipe. The rainwater drainage pipe will directly discharge water into the river, and the sewage generated by the factory will be discharged into the factory sewage, and then discharged from the factory sewage to the sewage drainage pipe. The sewage drainage pipe will pass through the treatment plant before being discharged into the river. The treatment plant will purify the sewage and discharge it into the river through the sewage drainage pipe after it meets the standards. The staff needs to check the status of the pipeline in the inspection well at set intervals to prevent problems with the pipeline.

[0009] The beneficial effects of this solution are: 1. The use of two pipes for separate discharge can reduce the workload of the treatment plant, and the rainwater is directly discharged, which improves the drainage efficiency. 2. The inspection well is equipped with air holes to ensure that the toxic gas in the inspection well is volatilized and the safety of the staff is guaranteed. 3. The air holes are also equipped with filter plates to prevent pedestrians from dropping things into the well. At the same time, the filter plates are detachable, which is convenient for the staff to observe the conditions in the well through the air holes.

[0010] Furthermore, it also includes an adjustment mechanism, which includes a connecting rod, a base plate and a cleaning rod. The filter plate is slidably connected to the air vent, one end of the connecting rod is fixedly connected to the manhole cover, and the other end is fixedly connected to the base plate. The connecting rod is located inside the inspection well, the base plate cooperates with the air vent, the cleaning rod is fixedly connected to the base plate, and the cleaning rod cooperates with the filter plate. The inspection well needs to prevent a large amount of external water from entering on the one hand, and on the other hand, it needs to ensure air permeability. When the mechanism is in a rainstorm, when the filter holes of the filter plate are not enough to discharge water, water will accumulate on the filter plate, and the filter plate will move down due to the gravity of the water. When the filter plate moves down, the cleaning rod will be inserted into the filter holes of the filter plate, blocking the filter plate, so that water cannot enter the inspection well, and prevent excessive water accumulation inside the inspection well from causing blockage of the drainage system. When the rain stops, the rainwater on the filter plate will slowly drain or evaporate, and the filter plate will reset at this time to continue to ventilate. This mechanism can prevent rainwater from entering through the air vents when it rains heavily. At the same time, the cleaning rod can also clean the filter holes when it rains heavily to prevent the filter plate from being blocked.

[0011] Furthermore, a water storage tank is provided on the filter plate, which makes it more accurate to judge the rainwater when it rains, and makes it easier for the rainwater to stay on the filter plate when it rains.

[0012] Furthermore, it also includes a concrete well ring, which is arranged between the ground and the well seat. The concrete well ring is used to fix the inspection well cover to ensure that the well cover is stably and reliably installed at the well mouth. The well ring provides a solid foundation that can bear the weight of vehicles and pedestrians.

[0013] Furthermore, it also includes an anti-fall net, which is detachably fixed to the well wall. The anti-fall net can prevent pedestrians from falling directly into the well and causing casualties when the well cover is lost. Moreover, the anti-fall net is detachable, so when the staff needs to go down, they can remove the anti-fall net. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0018] Basically Figure 1 As shown:

[0019] The pipe network construction adopts jacking construction, and the overall process flow is: measurement and layout of the well center → installation of equipment and rails → lifting of pipes into place → manual excavation and excavation → start of jacking → measurement, control and correction → pipe assembly → pipe jacking → excavation, excavation and jacking of the second section of pipe... → jacking force is close to allowable stress → placement of relay room (if necessary) → continue jacking as above → ... jacking into place → exit from the hole, removal of tool pipes → re-measurement of the entire line → completion of jacking → water-tightness test.

[0020] The construction site of the working pit is under closed management, with 2.5m high prefabricated enclosures set up on all four sides. The ground 4 in the field is all hardened with C20 concrete with a thickness of 20cm. The surrounding area of ​​the working pit is built with bricks to prevent water from the ground 4 from flowing into the working pit. A vertical truss car is installed on the working pit, and special soil stacking areas, pipe section stacking areas, power distribution rooms, generator rooms, air compressor rooms, tool rooms, etc. are set up. The diameters of the jacking pipes are: DN2000mm, DN1200mm, DN1000mm, and DN800mm. According to the jacking distance of 100m between the working pit and the receiving pit, a relay room is required according to GB50268-2008 "Construction and Acceptance Specifications for Water Supply and Drainage Pipeline Engineering". The pipe material is reinforced concrete jacking pipe, which has strong corrosion resistance and no additional anti-corrosion treatment. It is produced by core mold vibration. The technical requirements meet the relevant requirements of "Reinforced Concrete Drainage Pipe for Jacking Construction Method" (JCT 640-2010) and design drawings. The jacking pipe diameter of this project is 800~2000, and the minimum pipe diameter allows people to bend down and walk in the pipe. There is no groundwater or little groundwater, and the line is straight. The soil quality of the stratum through which the pipe passes is good, so hand-dug jacking is used. There is no jacking machine in the jacking pipe, and people dig the soil in the pipe.

[0021] When using pipe jacking construction, a working well and a receiving well need to be built at the starting end and the receiving end of the pipeline respectively. A group of oil cylinders with a long stroke (also called the main station oil cylinder, referred to as the main oil cylinder, commonly known as the jack) are arranged behind the jacking axis in the working well. They are generally arranged symmetrically, such as 2, 4, 6 or 8, and the number depends on the size of the pipe diameter and the size of the jacking force. The pipeline is placed on the guide rail in front of the main oil cylinder, and the pipe jacking machine is installed at the front end of the pipeline. When the main oil cylinder is jacking, the pipe jacking machine opens the circuit, pushes the pipeline through the through-wall pipe on the wall 8 of the working well, and pushes the pipeline into the soil. Then, people enter the pipe jacking machine through the pipeline, and under the protection of the pipe jacking machine, dig the soil at the front end of the pipe jacking machine, and the excavated soil is transported to the working well through the pipeline. When the main oil cylinder reaches the maximum stroke, it retracts, puts in the jacking iron, fills the retracted stroke, and the main oil cylinder continues to jack. In this way, the jacking iron is continuously added, and the pipeline continues to extend into the soil. When the pipes on the guide rails in the well are almost all pushed into the soil, retract the main cylinder, lift out all the jacking irons, lower the next section of the pipe into the working well, install it behind the previous section, and continue to push it in according to the above steps. Repeat the construction cycle until the jacking is completed.

[0022] This solution provides a pipe network diversion drainage system, including a rainwater drainage pipe 1, a sewage drainage pipe 2, an inspection well 3, a rainwater collection well, a factory sewage treatment plant and a treatment plant. The rainwater drainage pipe 1 is used to transport rainwater; the sewage drainage pipe 2 is used to transport sewage; the rainwater collection well is used to collect rainwater, and the rainwater collection well is connected to the rainwater drainage pipe 1; the factory sewage is connected to the sewage drainage pipe 2, and the treatment plant is connected to the sewage drainage pipe 2.

[0023] As attached Figure 2 , Figure 3 As shown:

[0024] There are multiple inspection wells 3, and the inspection wells 3 are respectively arranged at the rainwater drainage pipe 1 and the sewage drainage pipe 2. The inspection well 3 includes a well cover 5, a concrete well ring 6, a well wall 8 and a well seat 7. The well seat 7 is fixedly connected to the well wall 8, and the well wall 8 is arranged on a concrete base 10. The well cover 5 is the same size as the well seat 7, so that the well cover 5 can be just embedded in the well seat 7, and the well cover 5 is provided with an extraction port to facilitate the staff to open the well cover 5. The concrete well ring 6 is arranged between the ground 4 and the well seat 7. The concrete well ring 6 is used to fix the inspection well 3 cover to ensure that the well cover 5 is stably and reliably installed at the wellhead. And the well ring provides a solid foundation that can withstand the weight of vehicles and pedestrians. There are multiple air holes 14 on the well cover 5, and the air holes 14 are provided with a filter plate 13 for filtering impurities.

[0025] The inspection well 3 also includes an adjustment mechanism 9, which includes a connecting rod 15, a bottom plate 17 and a cleaning rod 16. The filter plate 13 is slidably connected to the air vent 14. One end of the connecting rod 15 is fixedly connected to the manhole cover 5, and the other end is fixedly connected to the bottom plate 17. The connecting rod 15 is located inside the inspection well 3, the bottom plate 17 is located below the air vent 14, and the bottom is larger than the air vent 14. The number of the bottom plate 17 is consistent with the number of the air vent 14. The bottom plate 17 is fixed directly below the air vent 14 through the connecting rod 15. The cleaning rod 16 is fixedly connected to the bottom plate 17. The number of the cleaning rod 16 and the number of the filter holes 11 of the filter plate 13 are consistent, and the cleaning rod 16 and the filter holes 11 are arranged one by one. The end of the cleaning rod 16 is slightly smaller than the filter hole 11, and the bottom of the cleaning rod 16 is consistent with the size of the filter hole 11, so that the cleaning rod 16 is convenient to insert into the filter hole 11. The filter plate 13 is provided with a water storage tank 12. The water storage tank 12 makes it more accurate to judge the rainwater when it rains, and the rainwater is more likely to stay on the filter plate 13 when it rains.

[0026] It also includes an anti-falling net, which is detachably fixedly connected to the well wall 8. The anti-falling net can prevent pedestrians from falling directly into the well and causing casualties when the well cover 5 is lost. Moreover, the anti-falling net is detachable, so when the staff needs to go down, the anti-falling net can be removed.

[0027] As attached Figure 1-3 As shown:

[0028] The principle of this scheme is that this scheme adopts rainwater and sewage diversion drainage. When it rains, rainwater will flow into the rainwater collection well, and the rainwater collection well will discharge the rainwater into the rainwater drainage pipe 1. The rainwater drainage pipe 1 will directly discharge the water into the river, and the sewage generated by the factory will be discharged into the factory sewage, and then discharged from the factory sewage to the sewage drainage pipe 2. The sewage drainage pipe 2 will pass through the treatment plant before being discharged into the river. The treatment plant will purify the sewage and discharge it into the river through the sewage drainage pipe 2 after it meets the standards. The staff needs to check the pipeline status in the inspection well 3 at set intervals to prevent problems with the pipeline.

[0029] When it rains, water will accumulate in the water storage tank 12 on the filter plate 13, and the filter plate 13 will move downward due to the gravity of the water. When the filter plate 13 moves downward, the cleaning rod 16 will be inserted into the filter hole 11 of the filter plate 13 to block the filter plate 13, so that the water flow cannot enter the inspection well 3, and prevent the drainage system from being blocked due to excessive water accumulation in the inspection well 3. When the rain stops, the rainwater on the filter plate 13 will slowly drain or evaporate, and the filter plate 13 will reset and continue to ventilate. This mechanism can prevent rainwater from entering from the vent hole 14 when it rains heavily. At the same time, when it rains heavily, the cleaning rod 16 can also clean the filter hole 11 to prevent the filter plate 13 from being blocked.

[0030] The beneficial effects of this solution are: 1. The use of two pipes for separate discharge can reduce the workload of the treatment plant, and the rainwater is directly discharged, which improves the drainage efficiency. 2. The inspection well 3 is provided with a vent hole 14 to ensure that the toxic gas in the inspection well 3 is volatilized and the safety of the staff is guaranteed. 3. The vent hole 14 is also provided with a filter plate 13 to prevent pedestrians from dropping things into the well. At the same time, the filter plate 13 is detachable, which is convenient for the staff to observe the situation in the well through the vent hole 14. 4. This solution can block the vent hole 14 when it rains, and open the vent hole 14 for ventilation when it is not raining, which solves the problem of water easily entering the vent hole 14.

[0031] The above is only an embodiment of the utility model, and the common knowledge such as the known specific structure and characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the structure of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent.
