PASSIVE TAILINGS COMPACTOR

Автор: BROWN DOUG ROY

The Passive Tailings Compactor is a system of components for facilitating the continuous passive drainage and consolidation of fine-grained sediments in active and continuous deposition environments. The invention consists of a flotation device, an anchor mass, and a drainage conduit which acts as a tether between the flotation device and the anchor. The flotation device also serves to orient the drainage conduit horizontally. As water or sediment levels rise, the flotation device rotates, releasing drainage conduit wrapped around its axis. This allows the flotation device to move upwards, extending the drainage conduit passively. The flotation device uses asymmetrical fixed weights to resist lesser rotational forces. The drainage conduit serves to create a path of relatively high hydraulic conductivity, protected by a filter barrier, for the dissipation of pore pressures and consolidation of buried sediments. The anchor mass fixes the system in place. 16-. (canceled)7.

A self-starting negative pressure drainage system for draining groundwater in a slope, includes: a declined borehole, a pipe boot, a permeable pipe and a drain pipe; wherein the declined borehole is divided into a permeable drilling section and a sealed grouting drilling section; wherein the permeable drilling section is on a lower portion of the declined borehole, and the sealed grouting drilling section is on an upper portion of the declined borehole; a water stop ring made of water-expanding rubber is provided between the permeable drilling section and the sealed grouting drilling section; the permeable drilling section comprises the permeable pipe; a top of the permeable pipe contacts the water-expanding rubber; a cavity is formed in the permeable pipe, groundwater is capable of penetrating into the cavity via the permeable pipe; an inlet of the drain pipe passes through the water stop ring made of water-expanding rubber and is inserted into the permeable pipe; a gap between the drain pipe and the drilling wall of the sealed grouting drilling section is filled with the cement mortar. The infiltration of groundwater causes the water pressure in the permeable drilling section to rise, forcing the groundwater from the borehole to naturally flow out of the orifice. After the drainage process is started, siphon acts cause a negative pressure zone formed in the permeable drilling section to force the groundwater in the slope flows quickly to the borehole. The invention is capable of realizing the real-time continuous drainage in the deep portion of the slope, which solves the drainage treatment problem of the large landslide, and ensures a low engineering cost of maintaining the stability of the slope. 1.
