Description

Technical Field

[0001] This utility model relates to the field of sewage pipeline renovation, and in particular to a sealing structure for a sewage renovation well. Background Technology

[0002] The wastewater discharge path modification involves excavating a rectangular pit at the original wastewater pipeline modification point, constructing a rectangular modification well within the pit, breaking up the original wastewater pipeline at the modification point, and sealing off its downstream section. Simultaneously, a new wastewater pipeline is buried underground, connecting it to the modification well. Finally, the modification well is sealed with a capping structure, and the area around the well is backfilled. Wastewater enters the modification well through the original wastewater pipeline and then flows away through the new wastewater pipeline, thus achieving wastewater discharge through the modification.

[0003] The sealing structure in related technologies typically includes multiple rectangular cover plates, which are placed over the modified well with adjacent cover plates abutting against each other to seal the well. However, the sealing effect between adjacent cover plates is poor, and the odor from sewage can easily overflow into the backfill layer through the gaps between the cover plates. Over time, this poses a risk of surface odor backflow, which needs to be improved. Utility Model Content

[0004] To address the shortcomings of existing technologies, the purpose of this utility model is to provide a sealing structure for sewage well renovation, which can improve the sealing effect between two adjacent sealing plates, reduce the risk of sewage odor overflowing into the backfill layer, and thus reduce the risk of surface odor backflow.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a cover structure for a sewage modification well, comprising multiple horizontally arranged cover plates, wherein a first sealing plate is integrally formed at the upper end of one side of each cover plate and a second sealing plate is integrally formed at the lower end of the other side, wherein each first sealing plate and the second sealing plate are respectively arranged along the length direction of the cover plate, and the first sealing plate on the cover plate can be tightly overlapped and cooperated with the second sealing plate on the adjacent cover plate.

[0006] Optionally, each of the first sealing plates has a lower surface and each of the second sealing plates has an upper surface provided with an elastic sealing sheet, and the two sealing sheets on the first sealing plate and the corresponding second sealing plate can abut tightly.

[0007] Optionally, a sealing layer is provided on the lower surface of each of the sealing plates, the sealing layer extending and covering the lower surface of the corresponding second sealing plate, and the sealing layer is used to tightly abut against the wellhead of the modified well.

[0008] Optionally, each of the second sealing plates has a positioning post vertically fixedly connected to its upper surface, and each of the first sealing plates has a positioning groove on its lower surface for the corresponding positioning post to be tightly inserted.

[0009] Optionally, each of the four corners of the upper surface of the cover plate is provided with a lifting ring.

[0010] Optionally, each of the four corners of the upper surface of the cover plate is provided with a clearance groove, and the four lifting rings on each cover plate are respectively located in the corresponding clearance groove.

[0011] Optionally, each of the relief grooves is detachably connected to an elastic sealing block, the sealing block being used to seal the corresponding relief groove, and a lifting ring being fixedly connected to the sealing block.

[0012] In summary, this utility model has the following beneficial effects: 1. Because the first and second sealing plates on the two adjacent sealing plates can overlap tightly and the two sealing pieces on the first and second sealing plates abut tightly, the sealing effect between the two adjacent sealing plates is effectively improved, reducing the risk of sewage odor overflowing into the backfill layer, thereby reducing the risk of ground odor backflow. 2. Each sealing plate has a sealing layer on its lower surface, which extends and covers the lower surface of the corresponding second sealing plate. At the same time, the sealing layer can tightly abut against the wellhead of the modified well, thereby improving the sealing effect between the sealing structure and the modified well.

[0015] The present invention will be further described in detail below with reference to the accompanying drawings.

[0016] Reference Figure 1 , Figure 2A cover structure for a sewage modification well includes multiple horizontally arranged cover plates 1. The cover plates 1 are made of metal steel plates. Each cover plate 1 has a first sealing plate 2 integrally formed at the upper end of one side and a second sealing plate 3 integrally formed at the lower end of the other side.

[0017] Reference Figure 1 , Figure 2 Each first sealing plate 2 and second sealing plate 3 is arranged along the length direction of the cover plate 1. The width of the first sealing plate 2 and the second sealing plate 3 is the same, and the first sealing plate 2 on the cover plate 1 can be tightly overlapped with the second sealing plate 3 on the adjacent cover plate 1.

[0018] Reference Figure 1 , Figure 2 Each first sealing plate 2 has an elastic sealing sheet 4 on its lower surface and each second sealing plate 3 has an upper surface. The thickness of each first sealing plate 2 and second sealing plate 3 is about half the thickness of the cover plate 1, and the sum of the thicknesses of the first sealing plate 2 and the sealing sheet 4 is greater than half the thickness of the cover plate 1, so that the two sealing sheets 4 on the first sealing plate 2 and the corresponding second sealing plate 3 can fit tightly together.

[0019] Since the first sealing plate 2 and the second sealing plate 3 on the two adjacent sealing plates 1 can overlap and fit together tightly, and the two sealing pieces 4 on the first sealing plate 2 and the second sealing plate 3 are tightly abutted together, the sealing effect between the two adjacent sealing plates 1 is effectively improved, reducing the risk of sewage odor overflowing into the backfill layer, thereby reducing the risk of ground odor backflow.

[0020] Reference Figure 1 , Figure 2 Each cover plate 1 has an elastic sealing layer 5 on its lower surface. The sealing layer 5 extends toward the corresponding second sealing plate 3 and completely covers the lower surface of the corresponding second sealing plate 3. At the same time, the sealing layer 5 is used to tightly abut against the wellhead of the modified well, thereby improving the sealing effect between the cover structure and the modified well.

[0021] Reference Figure 1 , Figure 2 Each second sealing plate 3 has a positioning post 6 vertically fixedly connected to its upper surface, and each first sealing plate 2 has a positioning groove 7 on its lower surface for the corresponding positioning post 6 to be tightly inserted, thereby realizing the positioning of the sealing plate 1 and improving the connection stability between two adjacent sealing plates 1.

[0022] Reference Figure 2 , Figure 3Each cover plate 1 has a clearance groove 8 at one of its four corners on its upper surface. A steel lifting ring 9 is welded and fixed in each clearance groove 8 so that the cover plate 1 can be lifted by an external crane. Since the lifting ring 9 is located in the clearance groove 8, multiple cover plates 1 can be stacked to facilitate the transportation of the cover plates 1 by the staff.

[0023] Reference Figure 2 , Figure 3 Each clearance groove 8 is detachably connected to an elastic sealing block 10. The sealing block 10 is used to seal the corresponding clearance groove 8, and a lifting ring 11 is fixedly connected to the sealing block 10. After the cover plate 1 is assembled, the sealing block 10 is inserted into the clearance groove 8 to seal the clearance groove 8, thereby isolating the lifting ring 9 from the external environment, reducing the risk of corrosion of the lifting ring 9, and enabling the cover plate 1 to be safely and smoothly lifted when the modified well is inspected or repaired.

[0024] In this embodiment, the sealing sheet 4, the sealing layer 5, and the sealing block 10 are made of corrosion-resistant rubber material. Of course, in other embodiments, the sealing sheet 4, the sealing layer 5, and the sealing block 10 can also be made of other elastic materials such as corrosion-resistant silicone, which will not be listed in detail here.

[0025] The specific embodiments are merely explanations of this utility model and are not intended to limit it. After reading this specification, those skilled in the art can make modifications to these embodiments without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this utility model.
