[0035] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this application.

[0036] In addition, the present application may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not in itself indicate the relationship between the various embodiments and / or settings discussed. In addition, the present application provides various specific examples of processes and materials, but those of ordinary skill in the art may recognize the application of other processes and / or the use of other materials.

[0037] The present application is described below with reference to the accompanying drawings and specific embodiments:

[0038] Prefabricated underground wells are easy to install and have a stable structure. They are widely used in various working conditions in production and life. They are prefabricated with various specifications of steel and other materials according to their uses. Since they are mostly buried at a certain depth underground, in order to facilitate operation, manholes are often opened on the top, resulting in the strength of the top structure being relatively poor compared to other locations, and prone to deformation, damage or even collapse due to heavy pressure; especially underground wells set below the road surface, which are subject to high-frequency rolling of vehicles and pedestrians, which undoubtedly increases the risk of deformation and subsidence in the wellhead area, and also threatens the safety of vehicles and pedestrians.

[0039] To this end, an embodiment of the present application provides an underground well, which aims to improve the structural strength of the underground well to a certain extent, reduce the risk of deformation, subsidence or even collapse, and correspondingly improve the safety of its internal equipment and reduce maintenance frequency and cost.

[0040] Figure 1 A schematic diagram of the structure of an underground well in an embodiment of the present application is shown; Figure 2 Shows Figure 1 Left view of; Figure 3 Shows Figure 2 Top view of the .

[0041] See also Figure 1 , Figure 2 and Figure 3 In some embodiments, the underground well may include a well body 100 , a vault cap 200 , and a well cover 300 .

[0042] The well body 100 can be configured as a cylindrical member, i.e., a wellbore 110. The wellbore 110 is the main structure of the underground well, and is used to accommodate various equipment and form a certain operating space. The wellbore 110 is provided with a well bottom 120, with the top left empty, and a functional pipe 130 is opened on the side wall of the wellbore 110 for accommodating equipment such as installation pipelines.

[0043] The arch cap 200 is connected to the top of the shaft 110 and closes the shaft opening of the shaft 110 , and a manhole 210 is opened on the arch cap 200 ; the manhole cover 300 is correspondingly connected to the arch cap 200 to open and close the manhole 210 .

[0044] Among them, the arch cap 200 can be arranged to arch upward, and when subjected to a downward pressure force, the downward pressure force can be decomposed into partial horizontal force and downward force through the arched structure. Therefore, if the arch cap 200 is to be deformed and sunken, it is necessary to compress the arch cap 200 laterally and vertically at the same time to break the strength limit, so as to force the arch cap 200 to deform; thereby, the arched and gathered structural form of the middle part of the arch cap 200 can be utilized to increase the compressive resistance to a certain extent, and can have better compressive bearing capacity than the existing conventional flat-top underground wells.

[0045] In some embodiments, the arch of the vault cap 200 can be set to a spherical form with the convex surface facing upward. The distance from the highest point of the vault cap 200 to the plane where the edge of the vault cap 200 is located can be 200 mm. The size of the plane surrounded by the edge of the vault cap 200 matches the size of the cross section of the wellbore 110.

[0046] In some embodiments, in order to further strengthen the vault cap 200, a reinforcing structure 210 is provided on the inner side of the vault cap 200, so as to maintain the shape of the vault cap 200, increase the structural strength of the vault cap 200, increase the difficulty of deformation, improve the bearing capacity, and thus reduce the risk of sinking, damage, or even collapse.

[0047] The reinforcing structure 210 can be connected to the inner wall of the wellbore 110, so that the structural strength of the vault cap 200 can be further improved based on the wellbore 110, and the pressure on the vault cap 200 can be dispersed and transmitted to the wellbore 110, thereby further improving the bearing capacity and deformation resistance of the vault cap 200.

[0048] In some embodiments, the reinforcement structure may include a first rib plate 211 and a second rib plate 212 that are cross-connected to form a grid-shaped bracket, thereby reducing the complexity and weight of the reinforcement structure 210 while taking into account structural strengthening.

[0049] The first rib plate 211 and the second rib plate 212 may be connected between the inner wall of the dome cap 200 and the inner wall of the wellbore 110 , respectively.

[0050] It is worth noting that the edges of one side of the first rib plate 211 and the second rib plate 212 close to the arch cap 200 are also arranged to be arc-shaped, matching the spherical surface of the arch cap 200 to achieve good adaptation and fixation, and support the arch cap 200.

[0051] In some embodiments, in order to improve the pressure-bearing capacity of the wellbore 110, a first reinforcing ring rib 600 may be provided on the inner circumferential surface and / or the outer circumferential surface of the wellbore 110, which can improve the circumferential structural strength of the wellbore 110 and maintain the cylindrical shape, thereby ensuring the vertical member capacity and bearing the pressure from the arch cap 200.

[0052] Generally speaking, a plurality of the first reinforcing ring ribs 600 may be spaced apart along the axial direction of the wellbore 110 to improve the structural stability of the wellbore 110 as a whole.

[0053] In some embodiments, the first reinforcement ring 600 may be a circular ring with a width of ≥50 mm and a thickness of ≥12 mm, and the outer diameter or inner diameter may match the inner or outer dimensions of the wellbore 110. The number of first reinforcement rings 600 is determined according to the height of the wellbore 100.

[0054] In some embodiments, the interval between two adjacent first reinforcement rings 600 is 700-800 mm, and the material may be set to be steel, which can be welded to the wellbore 110.

[0055] In some embodiments, in order to reduce the wear of the arch cap 200 caused by the covering soil in the wellhead area, a connecting tube 500 connected to the manhole 210 may be provided on the arch cap 200, and the well cover 300 is connected to the tube mouth of the connecting tube 500; thus, after the underground well is set underground, a covering soil of a certain thickness may be provided between the arch cap 200 and the well cover 300 to facilitate road construction and road surface leveling; on the other hand, after the road surface is rolled over by vehicles for a long time, the covering soil will be compacted with the surrounding ground and can be evenly stressed, thereby reducing the heavy pressure of ground vehicles, pedestrians, etc. on the arch cap 200 to a certain extent, maintaining the reliability of the structural form of the arch cap 200, and preventing the upper part of the underground well from protruding on the road surface and affecting the appearance.

[0056] In some embodiments, the manhole cover bracket 310 of the manhole cover 300 can be directly welded to the tube mouth of the connecting tube 500. A sealing strip can be further provided at the bottom of the manhole cover 300, and the sealing strip and the manhole cover are sealed to achieve sealing at the manhole cover of the underground well.

[0057] In some embodiments, in order to strengthen the connection strength between the connecting tube 500 and the vault cap 200, a second reinforcement ring 900 may be provided at the connection between the connecting tube 500 and the vault cap 200 to strengthen and reinforce the manhole 210 area and improve the bearing capacity of the underground well.

[0058] In some embodiments, the second reinforcement ring 900 is made of steel, and the connection of the second reinforcement ring 900 can be achieved by welding.

[0059] In some embodiments, the functional pipe 130 may include: an inlet pipe 131 and an outlet pipe 132 , which respectively correspond to the installation pipeline structures.

[0060] In some embodiments, a support frame 700 can also be set at the bottom of the well 120, and the support frame 700 is set at the pipe openings of the water inlet pipe 131 and the water outlet pipe 132 to support the pipes or equipment installed in the water inlet pipe 131 and the water outlet pipe 132, which helps to improve the bearing capacity of the wellbore 110.

[0061] In some embodiments, the support frame 700 may be a T-shaped support plate frame or may be made of steel.

[0062] In some embodiments, in order to facilitate the entry and exit of operators, a ladder 400 may be provided on the inner wall of the shaft 110 , and the ladder 400 may be located below the manhole 210 .

[0063] Correspondingly, the manhole 210 may be eccentrically disposed on the arch cap 200 to match the position of the ladder 400 .

[0064] In some embodiments, the lower part of the shaft 110 may also be provided with a fixing leg 800 for connection and fixing with the contact at the installation site. Specifically, the fixing leg 800 may be welded with the steel embedded parts arranged in the concrete foundation prefabricated on site, and the concrete foundation is prefabricated according to the specifications and dimensions of the shaft 100, so as to prevent the side pressure of the shaft 100 from being squeezed and pushed when a heavy-loaded vehicle passes, thereby avoiding displacement of the connecting pipeline caused by the squeezing and pushing, and avoiding deformation and cracking of the pipeline caused by excessive displacement of the pipeline.

[0065] In some embodiments, the various components of the underground well can be formed by welding, prefabricated, and installed on site as a whole.

[0066] In some embodiments, the underground well may be formed of steel material, and a protective layer may be provided on its surface to play an anti-seepage and anti-corrosion role, thereby extending the service life of the underground well.

[0067] In some embodiments, the protective layer may be coal tar epoxy or rubber coating.

[0068] To sum up, the underground well disclosed in the embodiment of the present invention, by setting an arc-shaped cap, utilizes the arched space structure formed by the arc-shaped cap to replace the plane structure, so that the arc-shaped cap has a coordinating effect of spatial bearing, thereby making the underground well have a higher bearing capacity; on the one hand, it is beneficial to improve the high bearing performance of the underground well under heavy-loaded roads, and reduces the deformation and subsidence risks of the underground well under heavy-loaded roads; on the other hand, it is beneficial to improve the durability of the underground well and reduce the maintenance frequency and cost of the underground well.
