Embodiments of the present disclosure generally relate to a pumping unit base and methods for operating with the pumping unit base. The pumping unit base may include a plurality of driven piles installed in the ground, and a metal platform fixedly attached to the plurality of driven piles, wherein the metal platform is positioned above the ground. The metal platform may be removed from the driven piles and reinstalled to the driven piles.

The present disclosure discloses a fiber reinforce plastic (FRP) composite material pile prepared by an FRP composite material. The FRP composite material pile includes: an FRP winding pipe, an FRP pultrusion hollow profile, and a connecting device. The FRP pultrusion hollow profile includes an outer ring pipe, an inner ring pipe, and a plurality of reinforcing bars. The FRP pultrusion hollow profile is pultruded at one time by pultrusion equipment, and fiber materials thereof are arranged in the longitudinal direction of the pipe. The FRP winding pipe is provided with circumferential fiber materials by taking the FRP pultrusion hollow profile as a membrane, and forms a composite pipe section with the FRP pultrusion hollow profile. The inner ring shape of the cross section of the FRP winding pipe is matched with the FRP pultrusion hollow profile. The FRP connecting device includes connecting plates, connecting bars, and connecting pins.

The subject invention pertains to a completely new pile splicing system called Grouted Sleeve Coupler Splice (GSCS) for Precast Concrete Piles (PCPs) as an innovative alternative splicing method for connecting driven PCP segments. The provided splicing method is applicable for preplanned situations and provides a durable, labor-friendly, rapid, and economical foundation construction method. In this system, to improve the structural performance, the entire sleeve coupler and a portion of the dowels are partially debonded in short lengths from surrounding concrete. This connection system is novel in conjunction with PCPs and for connecting separate precast pile segments. The provided system offers a completely unique and new method of connecting and splicing PCP segments and other prismatic prefabricated piles.

Disclosed is a pile connection for horizontally fixing an elongated beam for a foundation support system. In particular, disclosed is a pile connection including at least one pile sleeve and at least one coupling attaching the at least one pile sleeve to an elongated beam such that a pile within the at least one pile sleeve extends between a top and bottom of the beam. Such a configuration provides a cost-effective, modular, and scalable system that is easily installed and adaptable to a variety of different terrains.

Provided are a pile joint, a pile coupling structure, and a pile coupling method that allow firm uniting of piles to be coupled. A joint (10) for coupling two piles (12) comprises: a tubular body (16) into which each pile (12) provided with a key (14) on a periphery thereof is inserted through an end (16A) of the body (16); and a fitting portion (22) formed on the body (16) so as to be fitted to the key (14) by the insertion and rotation of the pile (12). The fitting portion (22) is formed with: a tapered shape having a surface (22A) that is inclined so as to become distant from the end (16A) of the body (16) as the surface (22A) extends in the direction of rotation of the pile (12); or a wedge shape for fitting between a projection and a pile.

The present utility model relates to a sleeve connector (100) for joining tubular metal posts (300), comprising locking regions (120) provided with a ring of locking protuberances (121) of height (ht), which corresponds to from 0.15 to 4% of the external diameter (D) of the locking region (120) in order to promote the locking together of the ends of the tubular metal posts (300) by means of the mechanical deformation of the locking protuberances (121).

A pile system for support structures includes at least two piles each having a first end, a second end, and a cylindrical elongate body. Each cylindrical elongate body has an inner surface and an outer surface, extends from the first end toward the second end, and defines an internal cavity with a longitudinal axis. Each pile further includes a transition region between the elongate body and the second end, the transition region including an annular seating shoulder disposed on the inner surface of the cylindrical elongate body that defines a step increase from a primary inner diameter to a secondary inner diameter. The first end of a first pile of the at least two piles is configured to be inserted into the second end of a second pile until a first distal edge thereof contacts the seating shoulder of the second pile.

A foundation support system and method of installing the foundation support system. The foundation support system includes a pier system for providing support beneath a foundation, a support member, and a heave plate attachable to a bottom surface of the foundation. The method includes driving a pier system using a ram, coupling a support member to the heave plate, and engaging the support member with the pier system.

A pile segment for building supports to level foundations, e.g., slabs, has a generally cylindrical body made of concrete, the outer vertical surface of the cylindrical body being comprised of alternating spaced crests and troughs.

The invention relates to a method for forming a connection between two pipe segments of different widths, preferably of a tower-like structure, in particular of a wind turbine. In order to be able to connect pipe segments of different widths more easily, reliably and cost-effectively to one another, it is provided that the wider pipe segment is pushed with one end partially over an end of the narrower pipe segment , that the pipe segments are positioned apart from one another by forming an annular gap between the pipe segments, that in the annular gap between the two pipe segments a separating layer extending in the longitudinal direction of the pipe segments and/or in the radial direction is provided, that the annular gap adjacent to the separating layer and at least one side of the separating layer is at least partially cast with a casting compound, that during the hardening of the casting compound the casting compound forms a firm connection on one side of the separating layer with only one of the pipe segments and/or the casting compound forms a firm connection on the other side of the casting compound , only with the other pipe segment and that the pipe segments after the hardening of the casting compound are separated again along the separating layer with the assigned separate connecting elements in particular formed by the hardened casting compound.
