Embodiment 1
[0034] refer to figure 1 , is a kind of pressure energy dissipating well for the connection of sewage pipe network under the dam disclosed by the present invention, comprising a well body 1, the top cover of the leaching is provided with a well cover 13 with holes, and the upper part of the well body 1 is connected with a water inlet pipe 11 , the lower part of the well body 1 is connected with a water outlet pipe 12. The well body 1 of the energy dissipation well has a reinforced concrete structure, which is poured with C25 concrete, and the steel bars are HRB335 grade steel. The seat slurry at the bottom of the well body 1, the well body 1 and the water inlet pipe 1:2 waterproof cement mortar is used for plastering triangle mortar between 11 and outlet pipe 12.
[0035] refer to figure 2 , the well body 1 is fixedly connected with a plurality of vertical and parallel baffles 2, the bottom of the baffles 2 is fixedly connected with the bottom of the well body 1, and one ver...
Embodiment 2
[0041] A construction process for a pressure energy dissipation well for connecting sewage pipe networks under a dam. The steps include: welding steel bars together, then erecting a formwork, pouring concrete to obtain an integrally connected baffle plate 2 and well body 1, and after the pouring is completed , tie steel bars at the bottom of the well body 1, set up a formwork on the side where the baffle plate 2 abutted against the drop platform 3 is away from the pre-cast drop platform 3, the gap between the baffle plate 2 and the well body 1 is blocked by the formwork, and then The drop platform 3 is poured, and after the drop platform 3 is poured, the filter screen cylinder 4 is put into the well body 1 .
