Description

Technical Field

[0001] This utility model relates to the field of inspection well technology, and in particular to an integrated rainwater and sewage inspection well. Background Technology

[0002] Before laying sewage and rainwater pipes, sewage pipes and rainwater pipes of appropriate diameters are usually selected based on water volume calculations, and corresponding rainwater inspection wells and sewage inspection wells are matched. Rainwater and sewage inspection wells are often set up separately, but are joined together when the pipes are laid.

[0003] In existing technologies, situations with narrow and limited space are often encountered, such as in historical districts and alleys, where the width is generally only 3-5 meters. However, the diameter of sewage pipes is generally DN300 (mm), and the diameter of rainwater pipes is generally DN300~DN400 (mm). The corresponding sewage inspection wells are 60X60 (cm, inner diameter) and 90X90 (cm, outer diameter), and the rainwater inspection wells are 90X75 (cm, inner diameter) and 150X135 (cm, outer diameter). After merging, the total width of the rainwater and sewage inspection wells reaches 2.4 meters. Due to the large width of the rainwater and sewage wells, they occupy a lot of street and alley space, which is not conducive to the laying of other pipelines. Furthermore, the existing rainwater and sewage wells need to be excavated and then built on-site (cast), which cannot guarantee the construction quality of the manholes. The slow construction speed will also affect residents' travel.

[0004] In addition, in existing technologies, the elevation of the storm and sewage inlets of inspection wells often cannot be accurately reserved according to the design elevation. Utility Model Content

[0005] To address the aforementioned issues, this application provides a structurally sound integrated rainwater and sewage inspection well, which effectively reduces the overall size while ensuring functionality, and allows for the adjustment of the opening elevation according to actual needs, making it particularly suitable for spaces with limited areas such as historical districts and alleyways.

[0006] The technical solution adopted in this utility model is as follows: A combined sewage and rainwater inspection well includes an upward-facing well base. The interior of the well base is divided into two independent spaces by a partition, forming an adjacent sewage well and a rainwater well. The side walls of the sewage well and the rainwater well each have two or more side openings spaced from top to bottom. One of the side openings of the sewage well is connected to an external sewage pipe to form the current sewage opening. A baffle plate is installed on the inner circumferential surface of the sewage well between the current sewage opening and the lower side opening. A baffle plate is installed at the side opening above the current sewage opening. One of the side openings of the rainwater well is connected to an external rainwater pipe to form the current rainwater opening. A baffle plate is installed at the side opening outside the current rainwater opening.

[0007] As a further improvement to the above technical solution: It also includes a manhole cover, the bottom surface of which extends downward along the circumferential edge to form a flange, which is fitted at the opening of the manhole seat; the top surface of the manhole cover is flush with the top surface of the manhole seat.

[0008] The height of the partition layer in the well seat is lower than the height of the circumferential wall of the well seat. The bottom surface of the well cover extends downward to form a rib opposite to the partition layer. The bottom surface of the rib extends downward to form a fitting ridge. The rib is installed by fitting the top surface of the partition layer through the fitting ridge.

[0009] The sewage well is a non-grounded well, while the rainwater well is a grounded well. The distance between the lower edge of the lowest side opening of the sewage well and the bottom surface is less than the distance between the lower edge of the lowest side opening of the rainwater well and the bottom surface.

[0010] In the sewage well, the side walls around the sewage well located between two adjacent side openings are provided with slots for mounting the baffle plate, and the baffle plate is provided with multiple buckles that fit into the slots along the circumference.

[0011] The baffle plate includes a plate body that matches the cross-section of the sewage well, and buckles are vertically arranged on the circumferential side wall of the plate body. The buckles are telescopically fitted onto the plate body; a matching magnetic attraction structure is provided between the buckles and the socket.

[0012] The inner wall of the well base located on the left and right sides and below the side opening extends inward to form protrusions. The cross-section of the protrusions is an L-shaped structure with the opening facing the side opening. The protrusions and the inner wall of the well base form a slot, and the baffle is installed into the slot from top to bottom.

[0013] The gear plate and the baffle are respectively provided with extraction ports for easy extraction and lifting.

[0014] Branch pipe openings are provided on the side walls of the sewage well and rainwater well.

[0015] The well base has a square structure with equal side lengths in cross-section, and the sewage well and rainwater well separated by the partition have rectangular structures with unequal side lengths in cross-section; or, the well base has a rectangular structure with unequal side lengths in cross-section, and the sewage well and rainwater well separated by the partition have square structures with equal side lengths in cross-section.

[0016] Compared with the prior art, the present invention has the following beneficial effects: This utility model realizes the integrated design of rainwater and sewage inspection wells, which effectively reduces the overall size while ensuring functionality, and can be used with appropriate opening elevations according to actual needs, making it especially suitable for spaces with limited areas such as historical districts and alleys. This utility model also has the following advantages: By reducing the overall size of storm and sewage inspection wells, the space occupied by them in streets and alleys is reduced, which helps to ensure the laying of other pipelines and indirectly protects the safety of surrounding buildings. The storm and sewage inspection wells are prefabricated and installed at corresponding locations in streets and alleys after prefabrication, which helps to ensure the quality of the inspection wells and improve the construction speed.

Detailed Implementation

[0029] The specific embodiments of this utility model are described below with reference to the accompanying drawings.

[0030] like Figure 1 As shown, this embodiment of a rainwater and sewage integrated inspection well includes an upward-facing well base 2. The interior of the well base 2 is divided into two independent spaces by a partition 21, forming an adjacent sewage well 22 and a rainwater well 23. The side walls of the sewage well 22 and the rainwater well 23 are provided with two or more side openings 3 from top to bottom. One of the side openings 3 of the sewage well 22 is connected to an external sewage pipe to form the current sewage opening. A baffle plate 4 is installed on the inner circumferential surface of the sewage well 22 between the current sewage opening and the lower side opening 3. A baffle plate 8 is installed at the side opening 3 above the current sewage opening. One of the side openings 3 of the rainwater well 23 is connected to an external rainwater pipe to form the current rainwater opening. A baffle plate 8 is installed at the side opening 3 outside the current rainwater opening.

[0031] In this embodiment, by using a partition 21 on the well base 2 to separate the sewage well 22 and the rainwater well 23, the integrated design of the rainwater and sewage inspection well is achieved; by setting two or more side openings 3 equipped with baffles 8 and installing baffle plates 4 in the sewage well 22, the corresponding opening elevation can be used according to actual needs, thereby improving the convenience and flexibility of actual use.

[0032] Also includes manhole covers 7, such as Figure 2 As shown, the manhole cover 7 includes a cover body 71, the shape of which is adapted to the manhole seat 2. The bottom surface of the cover body 71 extends downward along the circumferential edge to form a flange 72, which is fitted at the opening of the manhole seat 2. The top surface of the manhole cover 7 is flush with the top surface of the manhole seat 2, thus achieving a reliable fit of the manhole cover 7 above the manhole seat 2.

[0033] The height of the partition layer 21 in the well base 2 is lower than the height of the circumferential wall of the well base 2. The bottom surface of the well cover 7 extends downward to form a rib 73 opposite to the partition layer 21. The bottom surface of the rib 73 extends downward to form a fitting ridge 74. The rib 73 is fitted and installed with the top surface of the partition layer 21 through the fitting ridge 74.

[0034] In this embodiment, the partition 21 is recessed into the surrounding wall of the well base 2. When there is sufficient rainwater in the rainwater well 23, the rainwater in the rainwater well 23 can be opened by opening the well cover 7 to allow the rainwater in the rainwater well 23 to overflow into the sewage well 22 for cleaning. Of course, a high-pressure water gun can also be used to suck up the rainwater in the rainwater well 23 to flush the sewage well 22, which is convenient for the daily maintenance of the inspection well.

[0035] Sewage well 22 is a non-grounded well, while rainwater well 23 is a grounded well. The distance between the lower edge of the bottom side opening 3 of sewage well 22 and the bottom surface is less than the distance between the lower edge of the bottom side opening 3 of rainwater well 23 and the bottom surface.

[0036] Sewage well 22 is usually used as a non-grounding well. It has no sedimentation function. The height of the bottom of the pipe opening is basically the same as the bottom of the well. Therefore, the lower edge of the bottom side opening 3 in sewage well 22 has a small drop and is basically level with the bottom surface. At the same time, if a side opening 3 other than the bottom side opening 3 is selected as the current sewage opening, it is necessary to combine it with the baffle plate 4 as the bottom of the well in the current use state to ensure that sewage well 22 is a non-grounding well.

[0037] The rainwater well 23 is usually used as a ground-level well and has a sedimentation function. There is a distance between the bottom of the pipe opening and the bottom of the well. Therefore, there is a distance between the lower edge of the bottommost side opening 3 of the rainwater well 23 and the ground. When the bottommost side opening 3 is used as the current one, it can be ensured that the rainwater well 23 is a ground-level well.

[0038] In the sewage well 22, the side walls of the sewage well 22 located between two adjacent side openings 3 are provided with slots 20 for mounting the baffle plate 4. The baffle plate 4 is provided with multiple buckles 42 arranged around the slots 20; thus, the baffle plate 4 is installed on the inner wall of the sewage well 22 by mounting the slots 20 and the buckles 42.

[0039] The baffle plate 4 includes a plate body 41 that matches the cross-section of the sewage well 22. The buckle 42 is vertically arranged on the circumferential side wall of the plate body 41 and is telescopically fitted to the plate body 41. Through the telescopic structure of the buckle 42, the installation and removal of the baffle plate 4 relative to the inner wall of the sewage well 22 can be realized and facilitated.

[0040] A matching magnetic structure is provided between the buckle 42 and the socket 20, which promotes and protects the fitting between the buckle 42 and the socket 20.

[0041] Example 1 like Figure 3 As shown, the buckle 42 is telescopically slidably fitted in the groove 410 on the side wall of the gear plate 4. An elastic element 48 is installed between the buckle 42 and the groove 410, and the elastic element 48 causes the buckle 42 to retract into the groove 410.

[0042] The magnetic structure is a magnetic element 24 embedded in the socket 20, and the buckle 42 is made of a material that can be magnetically attracted by the magnetic element 24.

[0043] In the initial state before the baffle plate 4 is installed into the sewage well 22, the buckle 42 is retracted into the groove 410 by the action of the elastic member 48; when the baffle plate 4 is lowered into the sewage well 22, the buckle 42 gradually approaches and faces the socket 20. The buckle 42 is attracted by the magnetic attraction of the magnetic member 24, overcomes the elastic force of the elastic member 48, and extends out of the groove 410 until the buckle 42 is fitted into the socket 20 on the wall of the sewage well 22.

[0044] In this embodiment, the top surface of the socket 20 is set as an outwardly flared slope, and the top surface of the buckle 42 is set as a slope that matches the socket 20. When the stop plate 4 is installed on the sewage well 22, the slope provides a guiding function for the fitting of the buckle 42 and the socket 20. When it is necessary to remove the stop plate 4 from the sewage well 22, an external force is applied to the stop plate 4 to lift it upward, overcoming the magnetic attraction of the magnetic suction member 24. The slope guides the buckle 42 and, combined with the elastic force of the elastic member 48, causes the buckle 42 to retract relative to the groove 410, thereby realizing the removal of the stop plate 4 from the sewage well 22.

[0045] Example 2 like Figure 4 , Figure 5 , Figure 6 As shown, a knob 43 is installed in the middle of the top surface of the gear shift plate 4 body 41. The lower shaft 431 of the knob 43 is rotatably installed on the plate 41. Multiple stainless steel springs 44 are circumferentially wound around the shaft 431. A pull rod 45 is installed at the end of the stainless steel spring 44. The end of the pull rod 45 is installed with a corresponding buckle 42. The stainless steel spring 44 causes the buckle 42 to extend relative to the plate 41. The buckle 42 is telescopically slidably fitted into the groove 410 on the side wall of the gear shift plate 4. The plate 41 has a groove that communicates with the groove 410 for the stainless steel springs 44 and pull rods 45 to pass through and move and guide.

[0046] By rotating the knob 43, the stainless steel spring 44 is screwed in or out relative to the shaft 431. The stainless steel spring 44 pulls the pull rod 45 to move along its own length, thereby causing the buckle 42 at the end of the pull rod 45 to retract or extend relative to the plate 41.

[0047] In this embodiment, the pull rod 45 includes a main rod 451 that moves along the groove in the middle of the plate 41 in the length direction. The outer end of the main rod 451 is bent and extended into a bent portion 452. A buckle 42 is installed at the end of the bent portion 452. The bending portion 452 converts the movement of the main rod 451 in the length direction into the contraction of the buckle 42 relative to the side wall of the plate 41.

[0048] exist Figure 5 In the embodiment shown, the double-dotted line indicates the state in which the buckle 42 is retracted relative to the plate 41.

[0049] Example 3 like Figure 7 , Figure 8 As shown, unlike Embodiment 2, in this embodiment, the end of the stainless steel spring 44 is equipped with an active rod 46, and the inner end of the buckle 42 is equipped with a straight rod 47. The straight rod 47 is set perpendicular to the side wall of the plate 41. The end of the active rod 46 is bent and fitted with the straight rod 47. The plate 41 has a groove that allows the active rod 46 to pass through and move along the length direction, allows the straight rod 47 to pass through and move along the length direction, and communicates with the groove 410.

[0050] By rotating the knob 43, the stainless steel spring 44 is screwed in or out relative to the shaft 431. The stainless steel spring 44 pulls the drive rod 46, and the drive rod 46 pulls the straight rod 47, thereby causing the buckle 42 to retract relative to the plate 41.

[0051] In this embodiment, an elastic element 48 can also be installed between the straight rod 47 and the plate 41, combined with a stainless steel spring 44, to cause the buckle 42 to extend outward relative to the plate 41.

[0052] exist Figure 8 In the embodiment shown, the double-dotted line indicates the state in which the buckle 42 is retracted relative to the plate 41.

[0053] In Embodiments 2 and 3, the buckle 42 can be configured to have the same or similar structure as in Embodiment 1, depending on actual needs. For example, the top surface of the buckle 42 and the top surface of the socket 20 can be configured as matching bevels.

[0054] In actual operation, the telescopic structure of the buckle 42 relative to the plate 41 can also be set to other structural forms, so as to realize the telescopic structure of the buckle 42 relative to the plate 41, and realize the installation between the baffle plate 4 and the wall of the sewage well 22 through the matching of the buckle 42 and the socket 20.

[0055] exist Figure 9 In the embodiment shown, protrusions 31 extend inward from the inner wall of the well base 2 located on the left and right sides and below the side opening 3. The cross-section of the protrusions 31 is an L-shaped structure with the opening facing the side opening 3. The slot 32 is formed between the protrusions 31 and the inner wall of the well base 2. The baffle 8 is fitted into the slot 32 from top to bottom to realize the installation of the baffle 8 at the side opening 3.

[0056] In actual operation, the baffle 8 can also be installed at the side opening 3 in other structural forms. For example, a mounting hole 5 can be opened on the outside of the side opening 3, and the baffle 8 can be installed at the side opening 3 by fasteners and mounting holes 5.

[0057] The gear plate 4 and the baffle 8 are respectively provided with extraction ports 40, which facilitates extraction and lifting, and makes it convenient to install and remove the gear plate 4 and the baffle 8.

[0058] In this embodiment, a rubber seal can also be provided between the wall surfaces where the gear plate 4, baffle 8 and well base 2 meet, so as to ensure the relative sealing connection of the gear plate 4 and baffle 8 at the fitting point, and reduce or even avoid water leakage.

[0059] Branch pipe openings 6 are provided on the side walls of sewage well 22 and rainwater well 23.

[0060] In this embodiment, the branch port 6 is set according to actual needs and is used to connect with external pipelines.

[0061] Example 4 like Figure 10 As shown, the well base 2 has a rectangular structure with unequal side lengths in cross-section. The sewage well 22 and rainwater well 23, separated by the partition 21, have square structures with equal side lengths in cross-section, forming an integrated rainwater and sewage structure.

[0062] Example 5 like Figure 11 As shown, the well base 2 has a square structure with equal side lengths in cross-section, and the sewage well 22 and rainwater well 23 separated by the partition 21 have rectangular structures with different side lengths in cross-section, forming an integrated rainwater and sewage structure.

[0063] In this embodiment, by integrating the rainwater well 23 and the sewage well 22, the size of their splicing direction can be reduced to 1.44 meters, which is about 1 meter less than that of traditional wells. This fully meets the requirements for the layout and use of streets and alleys with limited space, and can also take into account the laying of other pipelines.

[0064] In this embodiment, by reducing the overall size of the storm and sewage inspection wells, the space occupied by the wells in the streets and alleys is reduced, which helps to ensure the laying of other pipelines and indirectly ensures the safety of surrounding buildings.

[0065] In this embodiment, the storm and sewage inspection wells are prefabricated and installed at the corresponding locations in the streets and alleys after prefabrication, which helps to ensure the quality of the inspection wells and improve the construction speed. When installing the inspection wells, a sand pad layer 1 is usually laid under the well base 2.

[0066] The method of using this utility model is as follows: The following explanation is based on the example of setting three side openings 3 in sewage well 22 and rainwater well 23 respectively.

[0067] For the sewage well 22, in actual use, if the inspection well is located at the beginning of the sewage pipe in the street or alley, and the sewage pipe elevation is relatively high, then the interior of the sewage well 22 is adjusted to the highest level, and the uppermost side opening 3 is connected to the external sewage pipe as the current sewage opening. A baffle plate 4 is installed between the two upper side openings 3. If the inspection well is located in the middle section of the street or alley sewage, then the interior of the sewage well 22 is adjusted to the middle level, and the middle side opening 3 is connected to the external sewage pipe as the current sewage opening. A baffle plate 4 is installed between the two lower side openings 3, and a baffle 8 is used to close the uppermost side opening 3. If the inspection well is located at the end of the street or alley sewage, then the interior of the sewage well 22 is adjusted to the lowest level, and the lowermost side opening 3 is connected to the external sewage pipe as the current sewage opening. A baffle 8 is used to close the two upper side openings 3.

[0068] For the storm drain 23, in actual use, if the manhole is located at the beginning of the storm drain in the street or alley, and the storm drain pipe is at a higher elevation, then the uppermost side opening 3 is connected to the external storm drain pipe as the current storm drain opening, and the two lower side openings 3 are closed with a baffle 8; if the manhole is located in the middle of the storm drain in the street or alley, then the middle side opening 3 is connected to the external storm drain pipe as the current storm drain opening, and the remaining two side openings 3 are closed with a baffle 8; if the manhole is located at the end of the storm drain in the street or alley, then the lowermost side opening 3 is connected to the external storm drain pipe as the current storm drain opening, and the two upper side openings 3 are closed with a baffle 8.

[0069] This utility model realizes the integrated design of rainwater and sewage inspection wells, which effectively reduces the overall size while ensuring functionality, and allows for the use of different opening heights according to actual needs, making it particularly suitable for spaces with limited areas such as historical districts and alleys.

[0070] The various embodiments in this specification are described in a progressive manner, with each embodiment focusing on the differences from other embodiments. The same or similar parts between the various embodiments can be referred to each other.

[0071] The above description is an explanation of the present utility model and not a limitation thereof. The scope of the present utility model is defined by the claims. Within the protection scope of the present utility model, any form of modification may be made.
