Abstract: A mounting plate and bolt assembly adapted for attachment to a top portion of a helice pier shaft. The helice pier shaft threaded into the top of a ground surface. The assembly is used for supporting various types of building, highway and other types of structures. The mounting plate and bolt assembly includes small circular upper and lower pierhead plates spaced apart and welded to the top portion of the helice pier shaft. Also, large circular upper and lower mounting plates with bolt holes are disposed next to the upper and lower small pierhead plates and held thereon using a plurality of threaded bolts received through the bolt holes. The bolt holes are disposed around an outer circumference of the large mounting plates. The top of the threaded bolts may be used for securing a base plate of a post. The post is used for supporting various types of structures thereon. The large mounting plates may be welded directly to the pier shaft if the movement of the post is not large.

Abstract: A helice pier coupling system used for used for soil stabilization, supporting building structures and similar applications. The coupling system provides a way of adding one or more pier shaft extensions to a helice pier shaft of a helice pier for extending the length of the pier. The pier shafts may have lengths of 5 feet or greater. The coupling system includes a first helice pier. The first helice pier having diagonal cuts at a lower first end and an upper second end of a pier shaft. The lower first end of the pier shaft can be used as a lead point when the pier shaft is driven into the soil surface. The upper second end of the pier shaft can be used with a shaft coupling for engaging a lower first end, having a mating diagonal cut, of a pier shaft of a second helice pier or the pier shaft extension. The first helice pier includes one or more helice plates.

Abstract: A method and jacking assembly used for forming a concrete foundation pierhead. The pierhead is attached integrally to a foundation and/or floor system. A plurality of pierheads are used for leveling the foundation and floor system. Each of the pierheads include a jacking assembly which is used for jacking the pierhead on top of a vertical support member. The vertical support member may be a helix pipe pier, steel beams, posts, piers and the like. The pier pipe is installed into a ground surface and next to the foundation. The method steps include excavating a hole next to the foundation and installing the vertical support to a selected depth in the ground surface. The jacking assembly is then attached to the foundation and to a top of the vertical support. The pierhead is then poured around the jacking assembly and next to the foundation and floor system and allowed to cure.

Abstract: A ground anchor device for securing a building foundation and other structures to a ground surface using the subject anchor device. The anchor device is designed to be self advancing when rotated into the ground surface to depths of 10 to 30 feet and greater. The device includes one or more hollow pipe sections coupled together and connected to a pipe extension with drill point. The pipe extension includes a helice therearound for helping advance the anchor device into the ground surface. The pipe extension and hollow pipe sections are driven into the ground using a kelly bar. The kelly bar includes one end having a square drive section which is received inside a square opening in a drive collar. The drive collar is mounted to an inner circumference of the pipe extension. When the kelly bar is rotated, the square drive section of the kelly bar engages the sides of the drive collar for rotating the pipe extension and pipe sections.

Abstract: A ground anchor device for securing a building foundation and other structures to a ground surface using the subject anchor device. The anchor device is designed to be self advancing when rotated into the ground surface to depths of 10 to 30 feet and greater and to engage and penetrate an underground rock formation for providing greater anchor stability. The device includes a plurality of external hollow pipe sections and a plurality of internal pipe sections. The external pipe sections are joined together with helix couplings. Each helix coupling includes a helix around the exterior surface of the helix coupling. The helice are used for driving the external pipe sections into the ground. The internal pipe sections are coupled together and have a hollow cross section with a lower end of one of the internal pipe sections attached to a rock bit.

Abstract: A drive device for injecting different types of fluids, chemicals and slurries into a subsurface for soil stabilization and removing fluids from the subsurface prior to treating a soil. The device is designed to be self advancing into the soil. When the driving of the device in the ground surface is completed, the device can be removed or it can be left in place for forming an anchor or load carrying pier. The device includes a plurality of external and internal hollow pipe sections. The pipe sections are joined together with couplings. Each coupling includes perforations therein and helices around the exterior surface of the coupling. The helices are used for driving the pipe sections into the ground. The perforations in each coupling are used for introducing fluids under pressure into the soil or for extracting fluids from the subsurface.
