Detailed Description

In order to make the objects, technical solutions and advantages of the present invention clearer, the following will explain in detail a preferred embodiment of the present invention with reference to the accompanying drawings to facilitate understanding of the skilled person.

As shown in fig. 1-2, the deep-cylinder energy-dissipating well with pressure flow discharging at the tail end in municipal pipeline engineering comprises an energy-dissipating well body 1, an anti-scouring block 2, a water inlet pipe 3 and a water outlet pipe 4.

The mouth of pipe of inlet tube 3 is even in energy dissipation well body 1 down, and scour prevention piece 2 sets up in the bottom of energy dissipation well body 1, and just sets up the export to inlet tube 3. Scour prevention piece 2 is big end down's trapezoidal square platform concrete structure, and the pre-buried resistant steel sheet 6 that erodees of up end, scour prevention piece 2 reduce from the washing force of the water under high pressure that inlet tube 3 carried to the energy dissipation well production, and its square platform structure, get into the energy dissipation well after to the rivers dispersion, have better energy dissipation effect. Through pre-buried resistant steel sheet 6 of erodeing on scour prevention is fast 2, utilize the high strength of steel sheet, reduce the erosion and wear.

An overflow weir 5 which divides the energy dissipation well body 1 into two areas is arranged in the energy dissipation well body 1; the water inlet pipe 3 and the water outlet pipe 4 are respectively arranged on two sides of the overflow weir 5, the horizontal section of the water inlet pipe 3 penetrates through the wall of the energy dissipation well body 1 to enter the energy dissipation well, the water outlet pipe 4 penetrates through the wall of the energy dissipation well body 1 to drain from the energy dissipation well, and the wall of the energy dissipation well is provided with a waterproof sleeve 10 for the water inlet pipe 3 and the water outlet pipe 4 to penetrate through.

Terminal pressure flows through inlet tube 3 among the municipal pipeline engineering and discharges to the energy dissipation well, reduces scouring force and energy dissipation back through scour prevention piece 2, flows over overflow weir 5 and gets into the drainage zone, and pressure can release, and rivers can steadily discharge away through drain pipe 3. Because the water flow speed of the water inlet pipe 3 is higher, the pipe diameter of the water outlet pipe 4 is required to be larger than that of the water inlet pipe 1 in order to avoid water congestion in the energy dissipation well and guarantee the swallowing capacity of the pipeline.

The energy dissipation well body 1 is a square well, the wall of the well of the energy dissipation well body 1 is provided with the splash guard 7 which is obliquely and upwards arranged, the included angle between the splash guard 7 and the well bottom is preferably 45 degrees, the splash guard 7 not only can play a role in further energy dissipation, but also can prevent water splashing. The splash guard 7 can be arranged for a circle along the wall of the energy dissipation well body 1, and can also be arranged at four corners of the well. The vertical height of the splash guard 7 is higher than that of the anti-scouring block 2, and the height is the length of the splash guard 7 multiplied by the sine value of 45 degrees.

Because inlet tube 3 pressure is great, for preventing it from rocking, be equipped with on the pipeline and prevent rocking support 8, be equipped with pipeline bracket 9 in the export of inlet tube 3. The steel plates are laid around and at the bottom of the well wall of the energy dissipation well body 1 and have good scouring resistance.
