An anchoring system installed on a bottom of a body of water. The anchoring system has a tube sheet with an access tube defining a flow channel therethrough. One or more water tubes pass through the tube sheet. Each of the water tubes defining a longitudinal channel through the tube sheet. Each longitudinal channel has an open end at the top side and a closed end below the bottom side. A plurality of flow channels pass through the tube sheet. A skirt extends from the bottom of the tube sheet and defines a volume within the skirt encompassing at least a portion of the water tubes and the flow channels. A shock absorber is coupled to the closed end of at least one of the plurality of water tubes. The anchoring system is installed using negative pressure and extracted using positive pressure.

The invention relates to a method to test friction resistance at inner and outer sidewalls of pipe pile through in-situ test. The method comprises embedding a strain sensor at inner or outer sidewalls of pipe pile to measure strain variation generating on pipe pile body under the action of load; carrying out static load test with the soil plug remaining in the pipe pile to obtain the strain variation .sub.p1j,i of the pipe pile body at the i.sup.th soil layer; taking out the soil plug remaining in the pipe pile and carrying out static load test to obtain the strain variation .sub.p2j,i of the pipe pile body at the i.sup.th soil layer; and obtaining the friction respectively at the outer and inner sidewalls of the pipe pile at the i.sup.th soil layer according to the measured strain variation, .sub.p1j,i and .sub.p2j,i.

A tool or extractor which is lightweight and portable. The tool includes a plate which is mountable to a mini-skid steer loader. The tool includes a first jaw member which is fixed. The first jaw member is preferably welded or otherwise attached to or engaged with the plate. The tool also includes a second jaw member. The second jaw member is moveable, such as via a hydraulic cylinder, and is pivotably connected the plate. The hydraulic cylinder is also preferably pivotably connected to the plate, and is controlled in order to affect a grip on a thing to be extracted. The mini-skid steer loader is then operable to pull up on the thing, and extract the thing from the ground.
