However, it is often difficult to construct the water drop. When the slope is a loose gravel layer, the foundation cannot be formed. In addition, the water flow velocity at the water drop outlet is relatively high, and it is easy to wash the water outlet slope, resulting in slope instability and water drop. damaged, thereby rendering the entire drainage system useless

Embodiment Construction
[0015] Such as figure 1 , figure 2 As shown, the stilling drainage facility of the present invention includes a stilling drainage tank 1, a front alveolar 2 in the stilling drainage pool, a rear alveolar 3, a water retaining sill 5, a sand washing drain pipe 6, a stilling pier 7, and front teeth The groove is at the front of the stilling drainage pool, the water retaining sill and the sand-washing drain hole are at the rear of the stilling drainage pool, the stilling pier is placed in the middle of the stilling drainage pool, the front end of the stilling drainage pool is connected to the diversion channel 9, and the The rear end of the power drainage pool is connected to the overflow channel 11, and the overflow channel plays a transitional draining effect.
[0016] The stilling pier 7 is rectangular columnar, equipped with three 50cm×50cm reinforced concrete stilling piers, one near the end of the diversion canal, and two side by side near the end of the overflow canal, an...

The invention relates to a force eliminating drainage facility. The force eliminating drainage facility is characterized by comprising a force eliminating drainage pool and further comprising a front tooth trough, a rear tooth trough, water blocking ridges, sand flushing drainage pipes and force eliminating piers, all of which are arranged in the force eliminating drainage pool; the front tooth trough is formed in the front portion of the force eliminating drainage pool, the water blocking ridges and the sand flushing drainage holes are formed in the rear portion of the force eliminating drainage pool, and the force eliminating piers are arranged in the middle of the force eliminating drainage pool; and the front end of the force eliminating drainage pool is connected with a diversion canal, and the rear end of the force eliminating drainage pool is connected with an overflow canal. The force eliminating piers are arranged in the pool in a quincunx manner, the water blocking ridges and the sand flushing drainage holes are formed in the tail end of the pool, the requirements of energy dissipation and drainage under different flows can be met, and deposition in the pool is prevented. The lower portion of the overflow canal is backfilled through rock blocks, and the anti-scrubbing capability and stability are improved. The force eliminating drainage facility is simple in structure, good in stability, convenient to construct and good in effect, and the canals and the pool are combined.
Description
technical field [0001] The invention belongs to the technical fields of water conservancy and hydropower engineering and highway engineering, and in particular relates to a drainage facility with a force-reducing function. Background technique [0002] At present, in water conservancy and hydropower projects and highway projects, there are common problems of ditch water treatment or slope drainage. The conventional method is to use drainage ditches (canals) to divert drainage, and set up falling water on high slopes (the floor is a stepped drainage ditch). However, it is often difficult to construct the water drop. When the slope is a loose gravel layer, the foundation cannot be formed. In addition, the water flow velocity at the water drop outlet is relatively high, and it is easy to wash the water outlet slope, resulting in slope instability and water drop. damaged, thereby rendering the entire drainage system useless. Therefore, in ditch water treatment and slope drainag...
