Abstract: A method and material for the manufacturing or retrofitting of fluid transport systems. The material chosen for the lining, or the pipe itself, will be selected based on physical properties such as a high impact strength and a low coefficient of friction. The low coefficient of friction will be essential to prevent the initial adhesion of foreign substances to the inner surface of pipes. In particular, an improved pipe composite will be useful in the lining or construction of water intake pipes where there is a well-recognized problem of the buildup of foreign substances including algae and other marine microorganisms. Therefore, by preventing buildup, the present invention will provide a more economical and efficient method to maintain the overall piping system.

Abstract: A retaining wall is formed from a plurality of segmented automobile tires. The sidewall segments are disposed horizontally to form a row with the ends of adjacent segments overlapping. Openings near the respective ends are aligned to cooperate with one another. A plurality of rows are formed and the openings are vertically aligned to form a height of the wall. Rods are disposed through the aligned openings to interconnect the rows. Tread segments of the tires are connected to the sidewall segments with the tread segments extending outwardly. The tread segments form support sections and may be connected to pilings to provide additional support for the wall.

Abstract: A grout gun for filling a rockbolt borehole with measured doses of grout includes a grout breech for accommodating a predetermined quantity of grout, which is usually in the form of a grout capsule. An elongate rubular barrel extends from the grout breech. Catalyst dosing means, comprising a catalyst dosing chamber communicating with the grout breech and a catalyst inlet pipe, provide a measured dose of catalyst. A compressed air inlet communicates with the catalyst dosing chamber, and a manual trigger valve is provided for controlling the flow of compressed air through the inlet. The valve is operable to propel both the measured dose of the catalyst and the predetermined quantity of grout simultaneously through the barrel under influence of the propellant.

Abstract: A process for constructing a self-sealing layer for landfills and waste dumps that use a base layer, cap layer, or liner to seal the area from water percolation through cracks or holes. A layer of soil is provided having specified characteristics which will become flowable under the effects of water moving through the layer. The soil is moved into the crack or hole by the water and accumulates until the breach is sealed. Geotextiles, otherwise known as textile mats, may be used inside the layer to reinforce the layer and enhance the self sealing effect of the flowable soil layer. Water glass and an appropriate gelling agent may be used in an embedding zone on either side of the mat to enhance the adhesion between the mat and the material in the cap, base, or liner.

Abstract: An earth retaining wall system is defined by a rectilinear three-dimensional matrix of tie elements, each substantially uniplanar in a horizontal plane and longitudinally elongated in a direction transverse to the retaining wall. Such tie elements are each rigidly coupled along one horizontal axis edge of an earth supporting side of the retaining wall. The tie element thusly defines a matrix or grid in a vertical plane. The system also includes passive pressure resistive members that are substantially uniplanar in a vertical plane which is also co-planar with the retaining wall. Such pressure resistive members are longitudinally elongated along a horizontal axis which is co-parallel with the retaining wall. Each of the pressure resistive members are rigidly secured to a surface of each tie element to define, in cross-section, a matrix in a vertical plane which is also normal to the retaining wall.

Abstract: A process for producing a landfill from a specified landfill site is disclosed. In the first step of this process, leachate from the landfill site is collected. Thereafter a specified shredded material is contacted with the leachate to age it, the horizontal permeability of the aged shredded material is then tested with a specified permeability tester; if the test is successful, the shredded material is used in the landfill and covered with waste material.

Abstract: A support device for maintaining drainage channel segments at a predetermined elevation above the earth, as surface material is poured and rises from the subgrade level to the finished grade level. Disclosed is an elongated rod with a sharp triangle-shaped tip which is driven into the earth and partially rotated so as to irretractably anchor the rod in the earth. Attached to the other end of the rod is a bracket for securely attaching to a drainage channel segment. Substantial stability is imparted to the support device by means of a flat plate which is forced against the earth with a nut which is threadedly engaged upon a threaded portion of the rod.

Abstract: Process for disposing of clay, shale or sand containing earth contaminated with petroleum products from a variety of remediation sites is disclosed. The surrounding contaminated earth to be remediated is first excavated. Then, any clay or shale which is present is separated from the other materials and transported to a site of a cement plant. The non-clay or non-shale material is disposed of in a non-hazardous landfill. At the cement plant, the clay or shale is mixed with other cement precursor raw materials and the mixture is ground to form a cement feed mix. The feed mix is introduced into a rotary cement kiln causing any remaining petroleum product contained therein to be volatilized and burned within the kiln as the cement clinker is formed. The clinker is then ground for the purpose of forming cement free of petroleum product.

Abstract: An apparatus for constructing subterranean structures, soil-chemicals mixture or soil-agents mixture by using a multi-shaft auger machine to mix soil with a chemical hardener in situ. As the auger shafts of the multi-shaft auger machine penetrate the soil, spiral flights attached to the auger shaft above the initial auger blades assist soil in passing by supporting structures located between adjacent auger shafts. The spiral flights both assist in raising the soil beyond the supporting structures and also prevent reagglomeration of the soil prior to passing by the supporting structures. The spiral flights have a diameter less than that of the auger blades attached to the shaft below the spiral flights and have a connection ranging from 360 degrees to 720 degrees around the shaft.

And a channel to be utilized by said method.

Abstract: In a tube eversion apparatus having a chamber in which eversion pressure is produced, that pressure is controllably sealed by providing curtain means communicating with the chamber through which the eversion tube slides and by providing inflatable means, preferably one on each side of the curtain means, which when inflated is caused to press against the curtain means, thereby to press the curtain means against the eversion tube sliding therethrough so as to produce the seal which maintains the eversion pressure in the chamber. A pair of sets of such inflatable means may be mounted on the apparatus one above the other with the individual sets of inflatable means being individually controlled, thus producing not only redundancy of the sealing means but also permitting enlarged or discontinuous portions of the eversion tube assembly to pass through the sealing means without interfering with the seal produced thereby.

Abstract: A system and method for adjustably connecting pre-cast wall facing panels to the soldier beams of a tie-back or anchor wall is provided, wherein the system comprises an array of panels stacked in rows having mutually adjacent side edge portions which are spaced apart from one of the soldier beams, a connecting column cast-in-place between the beam and the adjacent side edge portions of the panels for structurally interconnecting both of the panels to the beam, and an adjustable array of reinforcing members within the column for interconnecting the adjacent side edge portions of each of the panels with the beam and for reinforcing the resulting column. The depth of the cast-in-place connecting column advantageously accommodates variations in the distances between the beams and panels. In the method of the invention, a first row of wall facing panels is stacked in front of the soldier beams, and a first section of the connecting column is cast therebetween.
