The invention described herein includes materials and methods for segmental wick drain installation for versatile groundwater management. The invention comprises modified mandrels that may be coupled together for segmental installation wick drain installations to desired depths that are not achievable using currently known methods. Each modified mandrel is configured with a shoe coupler that may be permanently affixed to one end and configured with a means for securing the shoe coupler to a modified end of another mandrel. Each shoe coupler includes transverse bore holes through which set pins may be inserted that engage with an end of another modified mandrel with grooves corresponding to the locations of the bore holes when set pins are inserted. Once the wick drain is installed to the desired depth, the mandrels may be extracted and uncoupled by removing the set pins. The modified mandrels may be prefabricated and reused, ideal for multiple installations.
A subsidence monitoring system that employs an automated total monitoring stations (AMTS) in combination with a field-array of flush-mount prisms well-suited for monitoring settlement of roadways and other surfaces or structures. A method of installation of said field-array of flush-mount prism assemblies is also disclosed, along with tool for said installation.

A telescopic drill rod has at least two rod members disposed coaxially to one another, with the inner rod member being axially slidable relative to the outer rod member in a telescoping manner between an extended position and a retracted position. Both the inner rod member and outer rod member are equipped with joints at each end for connection to a drill head and/or another section of drill pipe. The joints also lock the inner and outer rod members in either the extended or retracted positions, and this is accomplished with a unique frusto-conical threaded engagement that is well-suited for transmitting pressure forces.

A frangibility device for creating a preferred breakage plane or weakness within cured columns such as rigid inclusions (RIs) and/or vibratory concrete columns (VCCs) comprises a cutting disc, an elongate strut attached to the center of the disc, and a detachable handle for turning. The disc comprises a thin geometric plate slit from center to periphery, so that a slicing wing can be bent downward at a shallow angle from the slit. The slicing wing advances the cutting disc through the cementious material of the uncured column. When the disc reaches the desired depth, the handle is removed and both disc and strut are left in place during curing.

Method and apparatus for field fabrication of socked perforated drains
A mobile fabrication solution for onsite assemblage of earth drains for ground stabilization that includes a despooling carousel for uncoiling corrugated tubing from a stock supply, and for feeding the stock tubing into an extrusion head unit. The head unit contains counter-rotating wheels that grip and drive the tubing out through a collet into a filter sock and into a collection trough. One end of a stock supply of fabric filter sock is attached to the collet exteriorly of the head unit to the collet and is unrolled along the trough. When the corrugated tubing is ejected it fills the sock within the trough and may be cut to the desired length onsite, eliminating waste.

A telescopic drill rod (2) has at least two rod members (20, 30} disposed coaxially to one another, with the inner rod member (30) being axially slidable relative to the cater rod member (20) in a telescoping mariner between an extended position and a retracted position. Both the inner rod member (30) and outer rod member (20) are equipped with joints at each end for connection, to a drill head and/or another section of drill pipe. The joints also lock the inner and outer rod members in either the extended of retracted positions, and this is accomplished with a unique frusto-conical threaded engagement that is well-suited for transmitting pressure forces.

A vertical drainage system for a heap leaching operation comprising vertical drainage conduits for draining fluid pockets down through the strata of a heap pile. The drainage conduits are spaced in a parallel array throughout the ore heap, and are preferably in fluid communication from a top of said ore heap to said one or more collection pipes for draining trapped and avoiding slope or geotechnical failure.
