Description

Technical Field

[0001] The utility model relates to the technical field of observation wells, in particular to an observation well. Background Art

[0002] With the development of urbanization, solving the contradiction between urban tap water supply and drainage, improving the water delivery capacity of urban water supply, sewage, rainwater and other drainage pipes, reducing the frequency of pipe bursts and water leaks, and restoring the water delivery capacity that has decreased due to pipeline corrosion can provide safe and reliable drainage guarantees for urban water supply and drainage construction and economic development.

[0003] The layout of urban drainage pipes is intricate, and they are generally very long and underground. In addition, due to factors such as building planning and road planning, drainage pipes have intersections, turns, and even climbing and falling points. Moreover, according to different drainage requirements, the diameter and slope of the drainage pipe need to be changed accordingly. Therefore, in order to cope with the complex underground waterway environment, observation wells are generally buried underground to facilitate regular inspection and maintenance of underground drainage pipes. Observation wells are usually equipped with main pipes and branch pipes, and branch pipes are used to connect underground drainage pipes. Due to the underground burial of branch pipes, the pipe wall will also be under great pressure. Generally, the structure of the branch pipe is difficult to support, and the pipe wall is prone to deformation over time, affecting the sealing of the connection between the branch pipe and the underground drainage pipe.

[0019] 3. Beneficial effects

[0020] Compared with the existing known technologies, the technical solution provided by the utility model has the following beneficial effects:

[0021] (1) The utility model provides an observation well, in which the main pipeline is connected to the ground, which is convenient for maintenance personnel to go down the well, and the branch pipeline is connected to the main pipeline, which is convenient for maintenance personnel to go to each drainage pipeline and inspect and maintain the drainage pipeline. The first pipe body has a larger diameter than the second pipe body, which is conducive to observing the situation in the well from the first pipe body. The longitudinal section of the branch pipe wall of the branch pipe includes a straight structure and an arc structure, and the straight structure and the arc structure are connected to each other. The arc structure can disperse the load, reduce the stress concentration of the branch pipe wall, and improve the compressive strength and deformation resistance of the branch pipe.

[0022] (2) In an observation well of the utility model, the longitudinal section of the branch pipe wall is a straight line and an arc-shaped structure which are alternately connected, so that the arc-shaped structure is located on the opposite side of the circular section, and the arc-shaped structure can better withstand pressure. An inner concave section is provided between the arc-shaped structure and the straight line structure. The structural design of the inner concave section facilitates the structural forming of the branch pipe and avoids stress concentration on the one hand, and can enhance the pressure bearing capacity of the branch pipe on the other hand. The anti-retreat structure arranged around the outer side of the branch pipe can be clamped with the inner wall of the drainage pipe when the branch pipe is connected to the inner wall of the drainage pipe, thereby playing the role of anti-retreat and sealing.

[0023] (3) An observation well of the utility model includes an arch support in the reinforcement structure. The arch support can effectively disperse the load and reduce the stress concentration on the epitaxial plane. When the epitaxial plane is under pressure, the arch surface of the arch support can withstand a large pressure, and the support foot can withstand a large bending moment, which effectively increases the structural strength of the epitaxial plane. The arch surface of the arch support can be set toward or away from the epitaxial plane, both of which can increase the deformation resistance of the epitaxial plane. The reinforcement ribs in the reinforcement structure can increase the structural rigidity of the epitaxial plane and further improve the support for the epitaxial plane.

[0024] (4) In an observation well of the utility model, a plurality of stacking feet are arranged in the circumferential direction of the bottom of the second tube body. The stacking feet increase the torsion resistance of the main tube when the main tube is buried, and prevent the main tube from twisting and deforming. The stacking feet protrude toward the outside of the second tube body, and the outermost end of the stacking feet exceeds the outside of the first tube body. Since the caliber of the first tube body is larger than the caliber of the second tube body, when multiple observation wells are stacked, the second tube body of the upper observation well can be placed on the edge of the first tube body of the lower observation well through the stacking feet, so as to prevent the second tube body of the upper observation well from sinking into the first tube body of the lower observation well, thereby facilitating the subsequent transportation of multiple observation wells. The outer side of the main tube of the observation well can be provided with a plurality of branch pipes according to the layout of the underground drainage pipe, and the branch pipes are connected with the main pipe to facilitate the circulation of underground drainage. The inner side of the branch pipe is provided with an anti-recession groove, which can cooperate with the corrugation on the outer side of the drainage pipe to prevent the branch pipe from being separated from the drainage pipe. At the same time, it can also enhance the sealing of the branch pipe and the underground drainage pipe to prevent leakage. BRIEF DESCRIPTION OF THE DRAWINGS

[0037] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the accompanying drawings and embodiments. What is described here is only the preferred embodiment of the utility model. Those skilled in the art can think of other ways to implement the utility model based on the preferred embodiment, and other ways also fall within the scope of the utility model.

[0038] In the description of the present invention, it should be noted that the terms "center", "middle", "upper", "lower", "left", "right", "inner", "outer", "top", "bottom", "side", "vertical", "horizontal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operate in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first" and "second" are used for descriptive purposes only and cannot be understood as indicating or implying relative importance.

[0039] Example 1

[0040] Reference Figure 1-Figure 4 , this embodiment provides an observation well, including a main pipe 1 and a plurality of branch pipes 4. One end of the main pipe 1 is opened to connect to the ground, so that maintenance personnel can go down the well. One end of the branch pipe 4 is connected to the outer side of the main pipe 1, and the branch pipe 4 is connected to the main pipe 1, so that maintenance personnel can go to each drainage pipe and inspect and maintain the drainage pipe. The main pipe 1 includes a first pipe body 101 and a second pipe body 102. When the observation well is buried underground, the first pipe body 101 is set upward. Therefore, the diameter of the first pipe body 101 is larger than the diameter of the second pipe body 102, which is conducive to observing the situation in the well from the first pipe body 101 and is also convenient for maintenance personnel to go down the well for construction. The junction between the first pipe body 101 and the second pipe body 102 forms an epitaxial plane; the outer side of the second pipe body 102 is provided with a plurality of reinforcing structures, one side of the reinforcing structure is against the epitaxial plane, which can increase the support for the epitaxial plane, improve the structural strength of the epitaxial plane, and enhance the anti-deformation ability of the epitaxial plane.

[0041] In this embodiment, Figure 1 , Figure 2 and Figure 3 As shown, the reinforcement structure includes an arch support 2, the support legs of the arch support 2 abut against the epitaxial plane, the side of the arch support 2 is fixed to the outer side of the second tube body 102, and the arch support 2 is bent away from the epitaxial plane to form an arch surface. The arch surface of the arch support 2 can withstand greater pressure, and the support legs can withstand greater bending moments, which effectively increases the structural strength of the epitaxial plane. Moreover, the support legs of the arch support 2 abut against the epitaxial plane, which has more contact points than the arch surface contacting the epitaxial plane, and has better bending moment resistance.

[0042] It should be noted that the direction of the arch support 2 can also be adjusted, and the arch support 2 is bent toward the direction of the extension plane to form an arch surface, and the arch surface abuts the extension plane. At this time, the arch surface directly abuts below the extension plane, and the arch surface has a better pressure bearing capacity than the support foot, and can also enhance the deformation resistance of the extension plane.

[0043] In this embodiment, Figure 2 and Figure 3 As shown, a number of arch supports 2 are spaced apart along the circumference of the second tube body 102, which, on the one hand, provide multi-point support for the epitaxial plane, further increasing the support strength of the epitaxial plane. On the other hand, the spaced distribution can leave intervals between the arch supports 2, and the intervals can provide layout space for other components to prevent the arch supports 2 from structurally interfering with other components. The arch support 2 can be a single arch structure, that is, there is only one curved arch surface as a whole. The arch support 2 can also adopt a multi-arch structure, that is, it has multiple continuous curved arch surfaces as a whole. The single arch structure is simpler in process, while the multi-arch structure is better in support. In this embodiment, due to considerations of technical parameters and process procedures, a single arch structure is mainly adopted.

[0044] In addition, in addition to the arch supports 2 that are distributed at intervals on the circumference of the second tube body 102 in this embodiment, the arch supports 2 can also be continuously distributed along the circumference of the second tube body 102. The arch supports 2 of this structure can also play a supporting role on the extension plane, but this continuous structure is not conducive to the arrangement of other components. This embodiment still gives priority to the design method of the arch supports 2 distributed at intervals.

[0045] In this embodiment, Figure 2 and Figure 3 As shown, in addition to the arch support 2, the reinforcement structure also includes a reinforcement rib 5, which is fixed to the outer side of the second tube body 102, and one end of the reinforcement rib 5 abuts against the outer surface. The reinforcement rib 5 cooperates with the arch support 2 to increase the structural rigidity of the outer surface and further improve the support for the outer surface. A plurality of reinforcement ribs 5 are provided, and the plurality of reinforcement ribs 5 are arranged circumferentially along the outer side of the second tube body 102.

[0046] In this embodiment, the observation well needs to be buried underground, and a plurality of stacking feet 3 are provided at the bottom of the second tube body 102, and the stacking feet 3 are arranged along the outer circumference of the second tube body 102. The stacking feet 3 increase the torsion resistance of the main pipeline 1 when the main pipeline 1 is buried, and prevent the main pipeline 1 from twisting and deforming. Since the caliber of the first tube body 101 of the main pipeline 1 is larger than the caliber of the second tube body 102, in order to enable multiple observation wells to be stacked for placement or transportation, the stacking feet 3 protrude toward the outer side of the second tube body 102, and the outermost end of the stacking feet 3 exceeds the outer side of the first tube body 101. Since the caliber of the first tube body 101 is larger than the caliber of the second tube body 102, when multiple observation wells are stacked, the second tube body 102 of the upper observation well can be placed on the edge of the first tube body 101 of the lower observation well through the stacking feet 3, so as to prevent the second tube body 102 of the upper observation well from sinking into the first tube body 101 of the lower observation well, and facilitate the subsequent transportation of multiple observation wells.

[0047] As is known to all, the underground drainage pipelines in cities are often complex, usually consisting of many pipelines intersecting, and observation wells are usually arranged at the intersection of these pipelines. In order to make the observation wells adapt to the complex drainage pipelines, in this embodiment, Figure 1 and Figure 2 As shown, a plurality of branch pipes 4 are arranged on the outside of the main pipe 1, and the branch pipes 4 are connected with the main pipe 1 to facilitate the water flow in the underground drainage pipeline. The branch pipes 4 can be arranged with one, two, three or even more, and the specific number depends on the actual working conditions. The inner side of the branch pipe 4 is provided with an anti-recession groove 6, which can increase the sealing of the connection between the branch pipe 4 and the underground drainage pipe to prevent leakage. At the same time, when the drainage pipe is connected to the inner side of the branch pipe 4, the anti-recession groove 6 can also cooperate with the protruding corrugations on the surface of the drainage pipe to play an anti-recession function, avoid the branch pipe 4 from being separated from the drainage pipe, and increase the stability of the observation well structure. Since the anti-recession groove 6 is a groove-shaped structure, the outer side of the branch pipe 4 corresponding to the groove-shaped structure part will protrude to form an anti-recession protrusion, and the anti-recession protrusion protrudes to the outside of the branch pipe 4. When the drainage pipe is sleeved on the outside of the branch pipe 4, the anti-recession protrusion can cooperate with the concave corrugations on the inner side of the drainage pipe to play an anti-recession function. It can be seen that the anti-recession groove 6 of the branch pipe 4 can play a good anti-recession and sealing role no matter it is connected to the inside or outside of the drainage pipe, and is more practical.

[0048] from Figure 1-Figure 4 It can be seen that the longitudinal section of the branch pipe wall 401 of the branch pipe 4 includes a straight-line structure 402, four straight-line structures 402 are connected, and a concave section 403 is arranged between adjacent straight-line structures 402. The straight-line structures 402 and the concave sections 403 are connected to form a ring-shaped structure to enhance the structural strength of the branch pipe 4 and reduce the risk of compression deformation of the branch pipe 4.

[0049] Example 2

[0050] Different from the first embodiment, in this embodiment, Figure 5 As shown, the inner side of the branch pipe 4 is a smooth structure, and no anti-recession groove 6 structure is set. The smooth structure makes it easier for the branch pipe 4 to be connected to the underground drainage pipe. The smooth surface of the branch pipe 4 and the drainage pipe can be sealed by a sealing ring to prevent leakage and enhance the sealing requirements. The longitudinal section of the branch pipe wall 401 of the branch pipe 4 includes a straight structure 402 and a concave section 403. The concave sections 403 are connected between adjacent straight structures 402, and the four straight structures 402 are connected to each other.

[0051] Example 3

[0052] Based on the first and second embodiments, in this embodiment, Figure 6 and Figure 7As shown, the longitudinal section of the branch pipe wall 401 of the branch pipe 4 includes an arc structure 404, and the number of the arc structures 404 can be one, two, three or four. The arc structures 404 are connected to each other, and the arc structures 404 protrude to the outside of the branch pipe 4. The arc structure 404 can make the force of the branch pipe 4 more dispersed, thereby improving the structural strength of the branch pipe 4. When the number of the arc structures 404 is two, the arc structures 404 and the straight-line structures 402 are alternately connected, and a concave section 403 is also provided between the straight-line structure 402 and the arc structure 404, and the concave section 403 connects the straight-line structure 402 and the arc structure 404.

[0053] On the other hand, Figure 6 and Figure 7 As shown, a connecting pipe 405 is connected between the branch pipe wall 401 and the main pipe 1, and the left and right sides of the inner wall longitudinal section of the connecting pipe 405 are straight edges, and the upper and lower sides are arched edges. The upper and lower sides are arched edges, which can bear a larger load, are conducive to stress dispersion, improve the structural strength of the connecting pipe 405, and reduce the risk of deformation. At the same time, the observation well branch pipe of this cross section can be adapted to the inner wall longitudinal section with straight edges on the left and right sides, arched edges on the upper and lower sides, and the same size of the pipeline, especially the water pipe, so as to smoothly enter and exit water.

[0054] It should be noted that the straight structure 402, the concave section 403 and the arc structure 404 described in the above embodiments are all shapes displayed by the longitudinal section of the branch pipe 4. The straight structure 402 is extended to form a straight surface, the concave section 403 is extended to form a concave surface, and the arc structure 404 is extended to form an arc surface. The pipeline structure of the branch pipe 4 is formed by connecting the straight surface, the concave surface and the arc surface.

[0055] Example 4

[0056] Based on the previous embodiment, in this embodiment, Figure 8 and Fig. 9 As shown, a connecting pipe 405 is connected between the branch pipe wall 401 and the main pipe 1. The inner wall longitudinal section of the connecting pipe 405 is circular. The inner wall longitudinal section is designed to be circular to increase the structural strength of the connecting pipe 405, and can be adapted to a corrugated pipe with a circular inner wall section, especially a water pipe, to facilitate the smooth inflow and outflow of water. Fig. 9 The upper, lower, left and right inner walls of the inner wall longitudinal section of the branch pipe wall 401 shown are all linear structures 402, and are connected by "m"-shaped concave sections 403 at the four corners, which can be adapted to pipes with this type of outer contour.

[0057] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
