Embodiment Construction

[0014] Enforcement of the present invention, will determine the structural dimension of drop-water well according to the pipe diameter of upstream and downstream pipelines, drop, drop-water well adopts concrete pouring or brickwork, should calculate well wall thickness according to the depth of well and surrounding soil condition.

[0015] The elevation view of the present invention is shown in figure 1 . Diffusion and converging counterflow energy dissipation drop well is mainly composed of shaft 1, water inlet pipe 2, water outlet pipe 3, water distribution tank 4, side orifice plate 5, middle orifice plate 6, flow channel 7, and water distribution port 8. A water distribution tank 4 is arranged at the connection between the upper part of the well shaft 1 and the water inlet pipe 2, and the water distribution tank 4 surrounds the well body 1 for a week. The water distribution tank 4 is provided with a water distribution port 8 towards the center of the well shaft 1, and the ...

Abstract

The invention discloses a diffusion and collection type reverse flow and energy dissipation drop well, and relates to the field of drainage and hydraulic engineering, in particular to urban drainage pipelines and structures achieving drop energy dissipation in hydraulic engineering. The drop well is mainly composed of a shaft, a water inlet pipe, a water outlet pipe, a water distribution trough, a side hole plate, a center hole plate, a runner and a water distribution opening. Water flow adopts diffusion and collection modes repeatedly in the drop well, when the water flow is diffused, the kinetic energy is decomposed to the surrounding, the water flow dispersion and energy dissipation effects are achieved, when dropping to the next level, the water flow is collected to the middle from the surrounding, the water flow hedge is formed in the middle of the drop well, the water flow energy in all the direction is same in size and opposite in direction, and the energy is reduced by means of the water flow. The drop well is suitable for the drainage pipelines and drop structures large in flow and fall in the hydraulic engineering.

Description

technical field [0001] The invention relates to a diffusion and collection type reverse flow energy dissipation drop well, which relates to the fields of drainage engineering and water conservancy engineering, in particular to structures for urban drainage pipes and water conservancy engineering drop water energy dissipation. Background technique [0002] Drainage pipes need to be equipped with drop wells when the drop is large. In the design of drainage pipelines in the prior art, standard drawings are generally used for the falling wells. For the falling wells in the current national standard drawing "06MS201 Municipal Drainage Pipeline Engineering and Auxiliary Facilities", the falling wells with a pipe diameter of 700-1650mm adopt stepped falling wells , The maximum drop is 2m, and the ladder-type drop well with a drop of 2m has a length of 4m in the well. In actual engineering, it is also very common for the upstream and downstream pipelines to have a drop of 7-8m, and...
