Description

Technical Field

[0001] This utility model relates to the field of municipal drainage pipeline technology, and in particular to a vortex sedimentation inspection well. Background Technology

[0002] Municipal stormwater or sewage pipe networks require the construction of sedimentation wells at regular intervals to accommodate sand and sludge removal. Conventional sedimentation wells consist of grooves installed inside inspection wells. However, conventional sedimentation wells are inefficient, and when the pipe drainage flow is high, the sludge and sand already deposited in the grooves can easily be washed into the downstream sewage pipes. Utility Model Content

[0003] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a vortex sedimentation inspection well, which can prevent deposited silt and sand from being washed back into the downstream sewage pipes.

[0004] A vortex sedimentation inspection well according to an embodiment of the present invention includes: a well body; an inlet pipe disposed on one side of the well body; an outlet pipe disposed on the other side of the well body, the elevation of the outlet pipe being lower than that of the inlet pipe; a spiral corridor spirally disposed in the well body, the inlet pipe and the outlet pipe being respectively connected to the two ends of the spiral corridor, the water flow direction being rotated 360 degrees in the spiral corridor; and a sand hopper disposed at the bottom of the well body, the sand hopper being connected to the spiral corridor, and the mud and sand in the spiral corridor being able to enter the sand hopper.

[0005] The following are at least some of the beneficial effects of a vortex sedimentation inspection well: It includes a well body, an inlet pipe, an outlet pipe, a spiral channel, and a sand hopper. The inlet pipe is located on one side of the well body. The outlet pipe is located on the other side of the well body. The elevation of the outlet pipe is lower than that of the inlet pipe. The spiral channel is spirally arranged within the well body. The inlet pipe and outlet pipe are respectively connected to the two ends of the spiral channel. The water flow direction rotates 360 degrees within the spiral channel. The sand hopper is located at the bottom of the well body. The sand hopper is connected to the spiral channel. The silt and sand in the spiral channel can enter the sand hopper. Sewage enters the well body from the inlet pipe and, guided by gravitational potential energy and the spiral channel, rotates. Due to the higher specific gravity of the silt and sand, it is deposited on the sidewalls and bottom of the spiral channel under the action of centrifugal force, and finally enters the sand hopper. Workers can clean the sand hopper periodically. The design of separating the sand hopper and the spiral channel avoids the re-carrying of deposited silt and sand into the downstream sewage pipes.

[0006] According to some embodiments of the present invention, the spiral channel includes an outer pipe wall, an inner pipe wall, and a bottom wall. The outer pipe wall is disposed on the well body, the inner pipe wall is disposed on the sand hopper, and the bottom wall is part of the surface of the sand hopper. The inner pipe wall and the bottom wall are provided with sedimentation slots. One side of the inner pipe wall is for water flow, and the other side is for the sand hopper. Mud and sand enter the sand hopper through the sedimentation slots.

[0007] According to some embodiments of this utility model, the cross-section of the sand hopper is trapezoidal.

[0008] According to some embodiments of the present invention, a manhole cover is also included, with the sand hopper located directly below the manhole cover.

[0009] According to some embodiments of this utility model, the width of the sedimentation joint is 15-25cm.

[0010] According to some embodiments of this utility model, the width of the sedimentation joint is 20cm.

[0011] According to some embodiments of the present invention, the connection between the outer tube wall and the bottom wall is smoothly transitioned.

[0012] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, wherein: Figure 1 This is a plan view of an embodiment of the present utility model; Figure 2 for Figure 1 Sectional view of section AA; Figure 3 for Figure 1 Sectional view of section BB; Figure 4 for Figure 1 A sectional view of section CC. Detailed Implementation

[0014] In the description of this utility model, it should be understood that the directional descriptions, such as up, down, front, back, left, right, etc., indicate the directional or positional relationship based on the directional or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0015] In the description of this utility model, the use of "first" and "second" is only for the purpose of distinguishing technical features and should not be construed as indicating or implying relative importance or implicitly indicating the number of technical features or the order of the technical features.

[0016] In the description of this utility model, unless otherwise explicitly defined, terms such as "setting," "installation," and "connection" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this utility model in conjunction with the specific content of the technical solution.

[0017] Reference Figures 1 to 4 This utility model discloses a vortex sedimentation inspection well, including a well body 10, an inlet pipe 20, an outlet pipe 30, a spiral channel 40, and a sand hopper 50.

[0018] The inlet pipe 20 is located on one side of the well body 10. The outlet pipe 30 is located on the other side of the well body 10. The elevation of the outlet pipe 30 is lower than that of the inlet pipe 20. A spiral channel 40 is spirally arranged in the well body 10. The inlet pipe 20 and the outlet pipe 30 are respectively connected to the two ends of the spiral channel 40. The water flow direction rotates 360 degrees within the spiral channel 40. A sand hopper 50 is located at the bottom of the well body 10. The sand hopper 50 is connected to the spiral channel 40. Mud and sand in the spiral channel 40 can enter the sand hopper 50.

[0019] Understandably, in this embodiment of the invention, sewage enters the well body 10 through the inlet pipe 20 and rotates under the guidance of gravitational potential energy and the spiral channel 40. Due to the higher specific gravity of the silt, it is deposited on the side walls and bottom of the spiral channel 40 under the action of centrifugal force, and finally enters the sand hopper 50. The sand hopper 50 can be cleaned periodically by the staff. The design of separating the sand hopper 50 and the spiral channel 40 avoids the erosion of the deposited silt into the downstream sewage pipe.

[0020] Reference Figures 1 to 4 The spiral channel 40 includes an outer pipe wall 41, an inner pipe wall 42, and a bottom wall 43. The outer pipe wall 41 is installed on the well body 10, the inner pipe wall 42 is installed on the sand hopper 50, and the bottom wall 43 is part of the surface of the sand hopper 50. The inner pipe wall 42 and the bottom wall 43 are provided with sedimentation slots 44. Water flows on one side of the inner pipe wall 42, and the sand hopper 50 is on the other side. Mud and sand enter the sand hopper 50 through the sedimentation slots 44.

[0021] Reference Figures 1 to 4 It is worth noting that in this embodiment of the invention, the cross-section of the sand hopper 50 is trapezoidal. The area of ​​its bottom is smaller than the area of ​​its top, which facilitates the later cleaning of the sand hopper 50.

[0022] Reference Figures 1 to 4 It also includes a manhole cover 11, with a sand hopper 50 located directly below the manhole cover 11.

[0023] Understandably, the manhole cover 11 is mainly used for the maintenance and upkeep of the manhole, and also facilitates the regular cleaning of the sand hopper 50. The manhole cover 11 can also prevent pedestrians from falling on the road.

[0024] It is worth noting that in the embodiments of this utility model, the width of the sedimentation joint 44 is 15-25cm.

[0025] Furthermore, in an embodiment of this utility model, the width of the sedimentation joint 44 is 20cm.

[0026] It should be noted that when the settling gap 44 is too wide, a large amount of water will enter the sand hopper 50, affecting the settling effect. When the settling gap 44 is too narrow, the mud and sand will not easily enter the sand hopper 50 through the settling gap 44. After testing, a settling gap width of 15-25cm yields the best results.

[0027] Reference Figures 1 to 4 It is worth noting that in the embodiments of this utility model, the connection between the outer pipe wall 41 and the bottom wall 43 is smoothly transitioned, thereby making the spiral corridor 40 free of dead corners and greatly improving the sedimentation effect.

[0028] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0029] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
