Horizontal Drains – Geotechnical Photo Album

Though they are called "horizontal drains," the drains are usually installed at a slight upward angle, to facilitate drainage. They are usually 200 feet to 300 feet in length, and cost about $10 per foot installed. This photo shows a drill rig installing a horizontal drain at La Esperanza Dam in Ecuador. A hole is drilled about 300 feet ...

Horizontal Drain - an overview | ScienceDirect Topics

Horizontal drains are commonly installed to draw down water levels in slopes to add stability. They do this by unweighting the slope material and reducing unwanted excess pore pressures as described in Section 7.1.1 (Figure 7.13).Horizontal drains are generally the best alternative when the depth (or distance into a slope) to desired dewatering is great and where the costs of excavation and/or ...

The drainage ditches shall be constructed using soil cement mixtures, reinforced concrete U-shaped gutters, stone pitching, or be of the unsupported types.

Part 11 HYDRAUGERS/ HORIZONTAL DRAINS

Horizontal drains, or "hydraugers," were first used to effect landslide repairs undertaken by the E. L. Ransome Construction Co. in Oakland, CA in 1940. These are advanced on a slightly upward slope to promote gravity flow out of the cased borehole Most state DOTs use hydraugers to enhance long-term slope stability of highway cuts and
