Its supplementary devices of structure.
Background technology
In Hydraulic and Hydro-Power Engineering, hydraulic structure is built so that the upstream and downstream formation height of water, very big so as to have
Energy, leads off to most of potential energy during downstream and is necessarily converted into kinetic energy, it is necessary to properly processed.Downstream river certainly will otherwise be caused
Bed is seriously washed away, or even causes bank slope to cave in and dam.So, the reasonable selection of energy dissipation measure and design, to hinge
Arrangement, dam safety and quantities are all significant.
Stiling basin is the main body of energy dissipation by hydraulic jump work, and its supplementary devices are arranged in stiling basin, can strengthen effect of energy dissipation, is shortened
Pond is long, reduces construction costs.The main task of energy dissipation measure is to try to consumption of energy in current internal drag and external drag,
The effect of its erosion damage is limited to greatest extent, or takes the measure of control current current to be chosen from outlet structure escape works so as to
Wash away riverbed but the safety of building and neighbouring bank slope will not be affected.At present conventional form of energy dissipater has：Choose streaming energy dissipating, bottom
Four kinds of modes such as streaming energy dissipating, the energy dissipating of surface current formula and Dissipation Energy in Solid Bucket.Flip trajectory bucket is choosing using outlet structure escape works exit
Stream bucket lip, torrent is let out by under and is thrown in the air, later falls into the riverbed farther out from building, the energy dissipating side being mutually connected with downstream current
Formula.But flip trajectory bucket washes away seriously to downstream, and deposit is more, tail water fluctuation and atomization are all larger.

First order buttress, second level buttress, the top of third level buttress are connected, three-level buttress height is different and form three-dimensional mistake
Bit space is arranged.
Net used by the first order plane mesh structure, second level plane mesh structure, third level plane mesh structure
Shape fiber concrete is the enhanced concrete of steel fiber.
The steel fiber adopts one kind with 0.9 ㎜ steel wires, and mesh size is the mesh grid of 10 ㎜ × 10 ㎜.
This utility model has the advantages that：
1st, current hard hit plane mesh structure, by multiple impact most of energy is eliminated, and stiling basin tail bank is eliminated
Remaining part energy；
2nd, the network structure of multistage contour equidistant poor arrangement changes former water (flow) direction, reduces flow rate of water flow, disappears step by step
Except flow energy, water flow stationary flowing in stiling basin is made, improve energy dissipation rate, protection force reduction pool bottom, reduce flood discharge so as to reach
The purpose that water smoke is produced；
3rd, current eliminate energy because of the network structure of per grade of contour equidistant poor arrangement of impact, clash into the energy of force reduction pool bottom
Measure less, the vibration produced to stiling basin and downstream so as to reduce because the impulsive force to base plate is little；
4th, compared to the stiling basin and its supplementary devices of horizontal layout, the energy dissipating construction of this utility model neutral body arrangement
More stable, energy dissipating vibration-isolating effect is more preferable.
