Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of municipal drainage pipeline, more specifically, relates to a pipeline inspection well sewage intercepting and dredging plugging integrated device and a construction method. BACKGROUND

[0002] In the urban drainage system, especially in the urban drainage pipeline, a certain amount of garbage and sundries are often carried, including street life garbage and surrounding washed leaves, etc. The sewage interception and plugging technology of the inspection well as a key node plays a crucial role in maintaining the normal operation of the drainage pipe network, preventing sewage overflow and environmental pollution. The inspection well is often set at the intersection of the pipeline, the turning place, the change of pipe diameter or slope, and every certain distance on the straight pipe section, which plays the role of connection, cleaning, and inspection of the pipeline, as well as the special role of changing the direction of water flow (elbow), converging (three-way), and changing the diameter.

[0003] At present, most inspection wells may have sludge and other objects flowing through during use, increasing the cleaning burden of the user, consuming a large amount of manpower and material resources, and being not conducive to the stable use of the drainage system. At the same time, when the garbage in the inspection well accumulates too much, it is not clear when to clean it in time, which is not intelligent enough. Secondly, the current urban sewage adopts a decentralized collection and centralized treatment operation and management mode, and the composition of sewage is becoming more and more complex and variable. Especially for the combined sewerage system in the city, the sundries carried by rainwater and sewage often cause blockage of the main pipe network, and affect the operation and management of the urban sewage treatment plant. For example, patent document CN218814238U discloses a sewage inspection well. Garbage enters the well shaft through the water inlet from the water inlet pipe, and after being filtered by the first filter screen, the water flow and garbage are left on the first filter screen. The water flow passes through the first filter screen and enters the bottom of the well shaft, reducing the risk of the water outlet of the inspection well being blocked. Since the first filter screen is inclined, when the garbage is intercepted to the first filter screen, large pieces of garbage will move away from the water outlet in the direction of the inclination of the first filter screen under the action of their own gravity, reducing the risk of the water inlet of the inspection well being blocked.

[0004] However, the technical solution disclosed in patent document CN218814238U still has the following technical problems: (1) when the garbage accumulates too much, it is not clear when to clean it; (2) the filter screen structure can only separate the garbage that cannot pass through the filter screen, and the sludge will still sink to the bottom of the well; (3) it is suitable for sewage inspection wells with the same cross section, and the applicability is not strong for variable cross section inspection wells; (4) it is suitable for inspection wells with obvious height difference between upstream and downstream pipes, and the applicability is not strong for inspection wells with no obvious height difference between upstream and downstream pipes.

7. A pipeline inspection well sewage interception, silt removal and plugging integrated device according to any one of claims 1 to 3, characterized in that: The blocking mechanism also includes a road surface (35) and a manhole cover (34) located on the ground and on the top of the inspection well.

8. A pipeline inspection well sewage interception, silt removal and plugging integrated device according to any one of claims 1 to 3, characterized in that: The airbag (31) is connected to one end of the slider metal rod (23), and the airbag (31) can be installed and removed outside the inspection well by pulling the rope (21) upward.

9. A pipeline inspection well sewage interception, silt removal and plugging integrated device according to any one of claims 1 to 3, characterized in that: The alarm water level (44) is the water level in the inspection well that connects the conductive plates (42) at both ends and forms a closed loop.

10. An integrated construction method for intercepting, desilting and plugging sewage in pipeline inspection wells, characterized in that: The invention is realized by using an integrated sewage interception, silt removal and plugging device for a pipeline inspection well according to any one of claims 1 to 9, comprising: S100: Build the drainage inspection well and install the inclined plate U-shaped filter after the masonry is completed, so that the upper end of the inclined plate U-shaped filter is against the bottom of the upstream drainage pipe. Then install the limit block, connect and fix the external chute metal hollow rod to the airbag, and install the external chute metal hollow rod and fix it with bolts and limit blocks; S200: Connect the cylindrical filter screen with the slider metal rod, connect the closing plate with the cylindrical filter screen, and place the slider in the slider metal rod into the outer wall groove of the external chute metal hollow rod. Tie the top of the slider metal rod to the rope. Place the cylindrical filter screen at the bottom of the inspection well, and connect the inverted U-shaped insulated wire to the alarm transmitter. The two bottom sections are connected to the two conductive sheets respectively. Then tie the inverted U-shaped insulated wire to the anti-fall grille net, install the anti-fall grille net, and hang the rope on the anti-fall grille net. Cover the inspection well cover to complete the installation of the inspection well. S300: When garbage and debris from upstream gradually enter the inspection well, they are collected on the closed plate through the inclined U-shaped filter and the cylindrical filter, and gradually accumulate. When the garbage and debris gradually accumulate to a certain level, the water level in the inspection well gradually increases; S400: When the water level rises to the alarm level, the two conductive sheets are immersed in the water, prompting the automatic alarm signal transmission device to form a closed loop, thereby triggering the automatic alarm to start sending a signal to the backend and arranging personnel and machinery for cleaning; S500: Before cleaning, open the anti-fall grid and lift the rope. The rope drives the metal rod of the slider to rise. After lifting it to the road surface, remove the metal rod of the slider and lift the cylindrical filter out of the road surface. Empty the garbage and debris and transport them to the disposal site. Then repeat step 2. The alarm desilting of the inspection well is completed. S600: Connect an external metal hollow rod to the chute and place the airbag connected to it at the bottom of the well. Connect the inflation device to the external metal hollow rod through the inflation tube. Start the inflation device, and the airbag is pressurized and inflated through the external metal hollow rod and the inflation tube to fully expand the airbag, ultimately achieving the effect of temporarily blocking the upstream or downstream pipeline of the inspection well. S700: When the blockage needs to be lifted, simply release the pressure and air to shrink the airbag, and then lift the airbag to a certain height and fix it. The temporary blockage of the inspection well is completed.
