A coastal slope drainage system

Abstract

The invention provides a coastal slope drainage system. The hydrodynamic force is placed in seawater, and the hydrodynamic device is fixed to the bottom of the seabed. The hydrodynamic device includes a water inlet chamber, a rotary vane cavity, a round wheel, a rotary vane groove, a rotary vane, and a spring. , drainage pipe, rotating shaft, water wheel cavity, water wheel blade, water tank, water diversion pipe is connected with the water inlet chamber of the hydrodynamic device, the water inlet chamber, the drain pipe are connected with the rotary vane cavity, and the circular wheel is arranged in the rotary vane cavity, and the circular wheel There is a rotary vane slot on the top, and rotary vanes are provided at both ends of the rotary vane slot. The rotary vane is fixedly connected to the rotary vane slot by a spring. There is a gap of 1‑2mm between the upper edge of the round wheel and the upper edge of the rotary vane cavity. Not subject to the resistance of the rotary vane cavity, the rotating shaft connects the round wheel and the water wheel blades, the water wheel blades are arranged in the water wheel cavity, a water tank is arranged on the upper part of the water wheel cavity, and an opening is set on the edge of the water tank so that flowing water can impact the water wheel blades.

Description

technical field [0001] The invention belongs to the fields of geotechnical engineering and coastal engineering, and in particular relates to a coastal slope drainage system. Background technique [0002] China's economy has developed rapidly and a large number of infrastructures have been built. However, most of China's geological topography and environment are complex, and geological disasters occur frequently. Among them, landslide disasters pose a huge threat to human production and life. The occurrence of most landslide hazards is related to the change of groundwater level. The rise of the groundwater level leads to an increase in the bulk density of the landslide, a decrease in the effective stress of the sliding surface, and a decrease in the shear strength, which in turn leads to the instability of the landslide. For slopes, when the water level in front of the slope drops rapidly, the groundwater inside the slope seeps out of the slope, generating seepage force, inc...

Problems solved by technology

[0005] Aiming at the defect that the siphon drainage method in the prior art is used to drain the coastal slope, after the siphon effect is suspended due to the drop of the groundwater level, the vacuum degree in the siphon tube is reduced, and the siphon effect is difficult to recover by itself
