Methods are provided for remediating contaminated soil. The methods may include collecting contaminated soil at a plurality of treatment sites. The contaminated soil at one or more of the plurality of treatment sites may be at least partially contained. The method may include heating soil at a first site with a plurality of heat sources to substantially reduce contamination of the soil at the first site. Soil at a second site may be heated using a plurality of heat sources. A portion of vapors p...

The soil sampler includes a sampling tube having a receiving space for receiving a soil sample, the receiving space being limited in a radial direction by a wall, being open in a distal direction for permitting soil to enter and in a proximal direction being limited by a transverse wall, the transverse wall having ducts for supplying and discharge fluid to the receiving space and a plug for closing the ducts, a free plug or piston being placed in the receiving space closely fitting in there and ...

The soil modifier includes a porous material obtained by dry distillation of refuse-derived fuel to pioneer a cheap way for effectively utilizing the refuse, thereby enabling the environment to be improved by modification of soil while promoting environment preserving disposal of the refuse. The porous material includes carbon, nitrogen, sulfur, phosphorus, potassium, and zinc.

A soil screening device includes a screen frame having a screening surface, and a supporting frame. The supporting frame may have rearwardly disposed rigid uprights supporting the screen frame. The screen frame is pivotally mounted to a first upper member mounted at an upper end of the uprights, for pivoting between a lowered position and an elevated position. The supporting frame has a base frame extending forwardly of the uprights. Upper members of the base frame have at least one wedge select...

An apparatus for taking a soil sample includes a drill pipe, a first driving gear for introducing the drill pipe into the soil, a sampling bush which movably fits into the drill pipe and a second driving gear for introducing the sampling bush into the soil.

A soil aeration apparatus may include aeration tines that are actuated by a relatively compact gear system that reduces the size and weight of the apparatus. In addition, a soil aeration apparatus may operate without a centrally disposed support shaft, thus enabling the tine-holder shafts to be positioned closer to one another and reducing the size of the apparatus.

This invention is a device for expediting the extraction of soil from a container drum utilized for holding soil samples during various tests. The device is comprised of a horizontally disposed base platform member having on the upper surface thereof two fixed vertically disposed stanchion members on the one end thereof, and in addition, affixed on such upper surface is a vertically disposed holder for supporting vertically a tray member to which is attached the container drum holding the core s...

A soil compactor for laboratory use to systematically and controllably coct specimens of soil and earth-rock mixture materials. The raising of a drop hammer after each strike to a pre-selected height is accomplished automatically by the use of a pneumatic cylinder in conjunction with sensing valves. A counter and deactivation valve are also provided so that the system will automatically shut off after the hammer drops a pre-determined number of times. Uniform compaction of each specimen is ensur...

Soil stabilization methods and apparatus whereby a material such as lime is introduced to soil beneath the earth's surface. The lime or other treating material is applied to the soil in slurry form. The slurried material may be introduced at depths from just beneath the ground surface down to depths of 15 to 20 feet, or even deeper.
