Description

Technical Field

[0001] The utility model relates to the technical field of drainage engineering in the municipal industry, in particular to a convection-type water-through energy-dissipating inspection well. Background Art

[0002] Mountainous cities have complex terrain, and some designed roads have large elevation differences with the natural terrain, requiring high fill. In order to communicate with the existing natural water system, it is necessary to reserve a circular culvert at the bottom of the high fill roadbed. The rainwater on the designed road needs to be discharged into the reserved circular culvert at the bottom, which will generate a huge waterfall head and damage the bottom circular culvert. Therefore, appropriate energy dissipation measures are needed to eliminate the waterfall potential energy of rainwater falling from the designed road to the bottom of the roadbed.

[0003] Traditional energy dissipation wells mainly include three types: vertical pipe type, vertical trough type and stepped type. However, these three types of drop wells have problems such as limited energy dissipation height, large footprint and unsuitable connection with water-passing circular culverts. Therefore, it is necessary to design a water-passing drop well suitable for mountainous cities to solve the above problems. Summary of the invention

[0004] The purpose of the utility model is to provide a convection water-passing energy dissipation inspection well based on the above-mentioned deficiencies of the prior art, which can receive water from two convection directions at the same time, and the bottom can be connected to the water-passing circular culvert. At the same time, multiple levels of energy dissipation platforms are arranged inside the energy dissipation inspection well, and each level of energy dissipation platform can be used for energy dissipation and maintenance to achieve effective water-passing energy dissipation.

[0005] The purpose of this utility model is achieved by the following technical solutions:

[0006] A convection-type water-flowing energy-dissipating inspection well comprises a well chamber, wherein a water inlet pipe is arranged at the upper portion of the well chamber, the water inlet pipe is communicated with the interior of the well chamber, and a water flow pipe is arranged at the lower portion of the well chamber, the water flow pipe is communicated with the interior of the well chamber. The well chamber is characterized in that: along the height direction of the well chamber, multiple levels of energy dissipation platforms are arranged inside the well chamber, energy dissipation grille cover plates are arranged on the energy dissipation platforms, and the positions of the energy dissipation grille cover plates on two adjacent upper and lower energy dissipation platforms are staggered so that water flows back and forth and falls in the height direction on the multiple levels of energy dissipation platforms.

[0007] The energy dissipation grid cover is arranged at the middle position or at both sides of the energy dissipation platform.

[0008] When the energy dissipation grid cover is arranged in the middle position of the energy dissipation platform, two energy dissipation grid cover plates are symmetrically arranged in the middle position of the energy dissipation platform, two energy dissipation retaining walls are arranged between adjacent sides of the two energy dissipation grid cover plates, and an energy dissipation folding plate is arranged between the two energy dissipation retaining walls.

[0009] When the energy dissipation grid cover is arranged on both sides of the energy dissipation platform, two energy dissipation grid cover plates are symmetrically arranged at the positions near the well chamber wall on both sides of the energy dissipation platform, and two energy dissipation retaining walls are symmetrically arranged in the middle position of the energy dissipation platform, and an energy dissipation folding plate is arranged between the two energy dissipation retaining walls.

[0010] The energy dissipation folding plates on the upper and lower adjacent energy dissipation platforms are arranged in a staggered manner.

[0011] A wellbore is arranged on the top of the well chamber, and the interior of the wellbore is communicated with the interior of the well chamber.

[0012] Steps are arranged in the well chamber and the wellbore.

[0013] A flow groove is arranged at the inner bottom of the well chamber, and the flow groove is communicated with the water pipe.

[0014] The advantages of the utility model are: it can receive water from two convection directions at the same time, the bottom can be connected to the water-passing circular culvert, and a multi-level energy dissipation platform is arranged inside the energy dissipation inspection well. Each level of energy dissipation platform can be used for energy dissipation and maintenance. At the same time, in order to prevent the energy dissipation platform from being blocked and unable to pass water normally, an overflow energy dissipation folding plate is arranged in the middle of the energy dissipation inspection well; the structure is simple and the construction is convenient. Compared with the traditional drop well, it has the advantages of small footprint, high energy dissipation efficiency, and not easy to be blocked. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Example: Figures 1 to 3As shown, the convection type water-through energy dissipation inspection well in this embodiment is mainly composed of a well chamber 1, a well shaft 4, a water inlet pipe 2 and a water-through pipe 3, wherein a multi-stage energy dissipation platform 5 is arranged in the well chamber 1, the water inlet pipe 2 is connected to the upper part of the well chamber 1, the water-through pipe 3 is connected to the lower part of the well chamber 1, a flow channel 11 is arranged at the bottom of the well chamber 1, and the top of the well chamber 1 is connected to the well shaft 4. An energy dissipation grid cover plate 6, an energy dissipation folding plate 8 and an energy dissipation retaining wall 10 are arranged on the energy dissipation platform 5.

From top to bottom, the two energy dissipation grid covers 6 of the first energy dissipation platform 5 are arranged in the middle of the energy dissipation platform 5, the two energy dissipation retaining walls 10 are arranged between the two energy dissipation grid covers 6, and the energy dissipation folding plate 8 is arranged between the two energy dissipation retaining walls 10.

[0022] At this time, the upper water flows into the well chamber 1 from the water inlet pipe 2, falls onto the first-level energy dissipation platform 5, is blocked by the energy dissipation retaining wall 10, and then is divided and aerated from the energy dissipation grid cover 6 and falls to the second-level energy dissipation platform 5 located below, and then passes through the left and right staggered waterfalls of the energy dissipation platform 5 to the next-level efficiency platform, and repeats this process until it reaches the bottom flow channel 11, and finally the water is discharged from the water pipe 3.

[0023] When the energy dissipation grid cover plate 6 is blocked, water flows over the energy dissipation retaining wall 10 and falls to the bottom flow channel 11 in a staggered manner from left to right between the energy dissipation folding plates 8 arranged on each level of energy dissipation platform 5 .

[0024] like Figure 2 As shown, each level of energy dissipation platform 5 is connected through steps 7. The top of the well chamber 1 is connected to the wellbore 4 and is connected through steps 7.

[0025] In the specific implementation of this embodiment: a C15 concrete cushion layer is used at the bottom of the well chamber 1.

[0026] In this embodiment, the energy dissipation platforms 5 can be arranged in multiple levels from top to bottom according to the height of the waterfall; preferably, the vertical spacing between the energy dissipation platforms 5 is 2000 mm.

[0027] The energy dissipation grid cover plate 6 is arranged alternately between the upper and lower energy dissipation platforms. During maintenance, the energy dissipation grid cover plate can be opened and the lower energy dissipation platform can be entered through the step 7; preferably, the grid pore size of the energy dissipation grid cover plate 6 is 50×50mm, the length is 1000mm, and the width is 1 / 2 of the width of the well chamber 1.

[0030] The size of the energy dissipation folding plate 8 is preferably 1000 mm in length and 1 / 2 of the width of the well chamber 1 .

[0031] The flow channel 11 is arranged at the bottom of the well chamber 1 . Preferably, the height of the flow channel 11 is 1 / 2 of the diameter of the water pipe 3 .

[0032] Although the above embodiments have described the concepts and embodiments of the purpose of the utility model in detail with reference to the accompanying drawings, ordinary technicians in this field can recognize that various improvements and modifications can still be made to the utility model without departing from the scope of the claims, so they are not described one by one here.
