Abstract:
A civil engineering structure for guiding a line in a slot in a surface area outdoors, said slot being formed by a milling or grinding process. A protective cover which consists of sub-pieces connected together in an articulated manner, extends above the line in the slot. The volume region of the slot in which the line is located is unfilled and is protected against expected compressive loads from the top by the sub-pieces. Because the sub-pieces are connected together in an articulated manner, the cover can be inserted without difficulty into longitudinal regions of the slot that have a curved course.
Abstract:
A pipe rack and a method for making a pipe rack where the pipe rack may include at least one foundation, two legs, and a horizontal support. The two legs are supported by the at least one foundation. Each of the two legs includes at least one aperture. The horizontal support has two ends. The first end is located in an aperture in a first leg of the two legs and a second end of the horizontal support is located in an aperture in a second leg of the two legs. A rod forms a joint between the foundation and one of the two legs. The rod is located in the aperture in the upper surface of the foundation and in an aperture in a lower surface in the one of the two legs.
Abstract:
A support system supports a pipe or conduit. In one exemplary embodiment, the apparatus, systems and methods include support beams extending across an excavated opening. For example, a pair of beams may be positioned to span the excavated opening with the opposing ends of the beams supported on the ground above the excavated opening. Support rods may be positioned to extend through and/or from the beams and into the excavated opening. In one exemplary embodiment, the support rods include a J-hook configured for receipt within an opening in pipe or conduit support members positioned beneath and supporting the pipe or conduit. In another exemplary embodiment, a pipe contacting support member is positioned beneath and contacting a pipe for supporting the pipe and fully excavating the pipe.
Abstract:
In one exemplary embodiment, curved sheet pile is driven underneath an existing conduit using a pile driver guided hydraulically by an excavator or other heavy machinery. By vibrating the curved sheet piles, the soil is placed in suspension, which allows the piles to be directed through the soil along an arcuate path that has a curvature that substantially matches the radius of curvature of the piles. Once the pile is positioned as desired, each individual pile sheet can be welded to one another to form a unitary structure. In one exemplary embodiment, the curved sheet pile is inserted beneath a conduit using a vibratory pile driver that rotates about a fixed pivot element on an excavator or other heavy machine for positioning the pile driver to advance the curved sheet pile along a fixed arc.
Abstract:
A construction method for installing underground pipes for high-tension cables uses a trough. The method includes the steps of forming an excavation trench by excavating the ground, installing the trough on the bottom of the excavation trench, pouring sand into the space section, placing the underground pipes on the sand, pouring again the sand onto the underground pipes, filling a gap formed between the trough and the excavation trench using sand and gravel, forming an upper protecting member on the trough, and performing surface treatment by using road pavement materials.
Abstract:
A resiliently-mounted through-foundation pipe coupling is provided that is suited for building plumbing applications. The resiliently-mounted coupling assembly is a length of straight plastic pipe preferably with pipe couplings on each end. The combined length of the pipe and associated couplings is selected to roughly match the thickness of the foundation. The combined pipe and associated couplings are covered with and bonded to a relatively thick layer of foam rubber elastomeric material. The combination of pipe and elastomeric layer is placed in the desired position in a foundation form before the foundation is poured. The elastomeric layer cushions the plastic pipe from the forces of being cast in place as the foundation is poured, and also provides resilience to the eventually installed piping system (connected to the through-foundation pipe fitting) against the motion of back-filled soil, and against alignment forces and mechanical loading of attached plumbing.
Abstract:
The expression ''''headwall'''' refers to the reinforced concrete structure which supports one end of a large pipe and retains earth fill on one side. Instead of building concrete forms on the site the headwall is poured into a form made from two identical lightweight plastic concave sections which are made to shape and size by vacuum forming identical plastic sheets placed back-toback to produce the mold which is a shell having the two sections attached together by plastic strips or the like. Each concave plastic section is vacuum formed with an intricate shape to produce an outwardly extending base and an upright retaining wall which may have a circular or oval-shaped hole passing through the walls to accommodate the drainage pipe. The plastic walls around the hole may be weak so as to distort around the pipe or may be split. The completed form has openings at the top through which concrete is poured. The bottom may be open so that concrete can come into contact with the irregular terrain or soil.
Abstract:
There is provided a novel form of back-fill for vertical retaining walls and a method of producing the same. The novel form of back-fill comprises a layer of moderately rigid, synthetic, polymeric foam located between the interface of a retaining wall and the soil which it is intended to retain. This plastic layer replaces sand or soil customarily used for this purpose. The novel back-fill makes possible the use of retaining walls of considerably lower strength than have been needed heretofore. The novel back-fill also permits easier drainage of the space behind the retaining wall.
Abstract:
An oil or like pipeline system is supported upon randomly spaced pillars each comprising a rubber or like container filled with a fluidic material such as styrofoam, sand water or the like.
Abstract:
This disclosure presents an anchoring element (20) for a charging station foundation (1), the charging station foundation (1) configured to receive a charging station (30) adapted to electrically charge a vehicle, wherein the anchoring element (20) comprises at least 50 weight percent plastic material and is adapted to receive first threaded fasteners (15) by means of which the anchoring element (20) may be attached to a foundation member (10) of the charging station foundation (1) and to receive second threaded fasteners (25) by means of which the charging station (30) may be attached to the anchoring element (20). The disclosure further presents a method of installing a charging station foundation, a method of installing a charging station and a use of an anchoring element (20) comprising at least 50 weight percent plastic material.
