摘要： 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.

摘要： A method and composition for reducing the swelling capacity of clay-containing soil, thus lowering volume change in soil, and thus enhancing the stability of soil, particularly expansive clay soil, in order that it is sufficiently stable, such that roads, pavements and some types of buildings and other structures can be securely constructed thereon. The method also minimizes any swelling and/or shrinkage in the soil under any such structures due to the movement of moisture in the soil, and thus minimizes damage and deterioration caused to such structures due to the presence of too much, or too little, water in the soil thereunder.
