Abstract: A method for reducing water leakage through sandbag dikes is disclosed, wherein a bentonite or other clay mud slurry is applied to the sandbags. The mud slurry may further include a water loss reducing chemical and/or a water blocking material. The mud slurry may be applied to the river side of the sandbags and may be covered with a plastic sheeting before the river level reaches the sandbags. The mud slurry, and any included chemicals and/or water blocking materials(s), form a coating on both woven plastic fabric and cloth sandbags as well as sandbags of non-porous plastic for reducing water flow through and between the sandbags. The plastic sheeting also makes it feasible to repair the dikes after the sandbags have become submerged by the rising water. That is, hoses can be inserted between the sandbags and the plastic sheeting for injecting the mud slurry at points having excessive leakage.

Abstract: A method for stabilizing and repairing whereby components are mixed to form an expandable foam which is injected under pressure in an expanded state behind or into the backfill material of an existing sheetpile seawall. Upon expansion, the foam displaces water and fills and seals cracks in the seawall and fills scoured voids in the backfill material. The method is also applied to rock revetment seawalls whereby the unexpanded foam is injected under pressure into the rock revetment. Upon expansion, the foam displaces water and fills and seals spaces in the rock revetment and interlocks the rock revetment.

Abstract: A pile forming system and method for forming a pile. The pile forming system comprises a top pile forming member, a bottom pile forming member, and an end plate assembled together to provide a complete pile form which can then be filled with concrete to form the pile. Additionally, the pile forming system incorporates a tip forming member which can be secured to one end of the pile form to form a sharp tip at one end of the pile facilitating driving the pile into a subsurface. Additional pairs of top and bottom pile forming members may be joined end to end to form longer piles. After the desired pile form is assembled, concrete is poured or pumped into the pile form through openings on the top surface of the pile form. Preferably, reinforcement bars or rebars which are coated with a non-permeable coating to prevent rust are placed in the pile form before the pouring of the concrete.
Abstract: A watercraft lift having raised and lowered positions is provided.

The intermediate transverse beam (32) is located between the front and rear transverse beams (28), (30) and at a height lower than the front and rear transverse beams. Forward booms (12) are pivotably connected to the base (10) at a location near the front transverse beam (28). Rear booms (14) are pivotably connected to the base at a location near the intermediate transverse beam (32). A watercraft support platform (24) is pivotally connected to the forward and rear booms (12), (14). The raising and lowering of the lift of the present invention is accomplished by an actuation assembly (26).

Abstract: A tire deflator and method of deflating a tire includes at least one support, a tire deflating device detachably secured to the at least one support and a deploying mechanism cooperating with the support and deploying the spike so as to be projected toward the tire of the vehicle and to penetrate and deflate the tire. The method of deflating the tire includes the steps of detachably securing a tire deflating device to the support, positioning the deploying mechanism in proximity with the support and activating the deploying mechanism so as to deploy the tire deflating device into the tire and deflate the tire. The degree to which the tire deflating device is deployed can be limited so that the tire deflating device does not become dislodged from a moving tire after being penetrated by the tire deflating device and thus does not create the potential of striking a bystander.

Abstract: An apparatus and method for stabilizing sloped embankments is disclosed which utilizes interlocking barrier elements to form a step-like, cascading barrier to erosion and to provide an inexpensive, easy-to-install and aesthetically attractive landscaping wall, planter or landscaping island. The scallop or channel-like shape of the barrier elements creates filler spaces which may be filled with concrete, soil or other filler materials and in which vegetation may be planted. Each row of barrier elements within the system is locked in place by slip restraint devices which function to prevent vertical slippage of the rows. Adjacent barrier elements on the front most row are held together by frontal locking elements.
Abstract: A segmented ring forms a set of latches for a tendon top connector on a floating platform. The latches reside in a housing and have either a groove or thread profile on an upper internal surface. The grooves interface with a mating groove profile on the tendon. The latches rotationally pivot backward and forward from the outer portion of the bottom surface. When the latches are forward, the profile in the internal surface engages the mating profile of the tendon top joint. When the latches are swung out, these profiles clear and permit the top joint to pass through the connector. Retraction of the latches is provided by application of force on the inside surface of an annular extension on the outer portion of the latches. This force can be provided by a variety of actuators. This top connector allows for passive dynamic engagement of the connector to the tendon top joint. When the latches are permitted to move inward, contact is made with the mating profile on the tendon top joint.
Abstract: An anchoring device includes a cam rod having a pair of dual-spiral grooves thereon which are orthogonal to each other. The cam rod is provided with a pedal. A direction-switching device is enveloped onto the cam rod. An anchoring root is releasably engaged to the lower portion of the direction-switching device. The direction-switching device includes a driving wedge which is engaged with a socket of the anchoring root. The anchoring root can be engaged or disengaged with the direction-switching device. When the pedal is depressed, the direction-switching device can be driven by the spiral grooves of the cam rod. The anchoring root that is attached to the bottom of the direction-switching device is also rotated. The anchoring root is then screwed into the ground. After the anchoring root is positioned, the cam rod and the direction-switching device can be removed therefrom and a pole can be inserted into a pilot hole within the anchoring root.
