| 20080310926 | ENVIRONMENT RESISTANT RETAINING WALL BLOCK AND METHODS OF USE THEREOF - The present invention relates to a retaining wall block that is resistant to damage and wear caused by the environment it is placed into. The deterioration resistant block is generally a hollowed frame or shell of a deterioration resistant material that is lightweight and is configured to accept and retain any type of filling material. The filling material provides weight and stability to the retaining wall block and also provides weight, stability and security to a retaining wall constructed of such blocks. | 12-18-2008 |

| 20110116876 | RETAINING WALL - A retaining wall for retaining matter on a side thereof comprising: a plurality of upwardly projecting primary sheet piles spaced apart from each other and having first structural properties comprising at least one of weight, size, strength and depth to be installed in a supporting body; and one or more intermediate panels of material arranged so as to span the gap between a pair primary sheet piles and to retain at least a portion of the retained matter, wherein the one or more intermediate panels have second structural properties different from the first structural properties. | 05-19-2011 |
| 20110142550 | METHOD FOR CONSTRUCTING A CHAIR-TYPE, SELF-SUPPORTED EARTH RETAINING WALL - The present invention provides a method for constructing a chair-type, self-supported earth retaining wall used for retaining external forces such as earth pressure prior to an excavation. The method of the present invention forms a first column of piles having a plurality of piles arranged along the circumference of the region to be excavated. Subsequently, the method comprises forming a second column of piles having a plurality of piles by consecutively perforating a plurality of holes by a predetermined spacing at predetermined positions outwardly from the first column of piles, along the circumference of the region to be excavated, inserting H-beams into the respective holes, filling left and right spaces of the webs of the H-beams with soil, and filling the outer spaces of the flanges of the H-beams with a flowable stiffening material. The method subsequently comprises interconnecting the first column of piles and the second column of piles by a connection member. The first column of piles and the second column of piles are formed along the circumference of the region to be excavated, with an outward spacing, and connected to each other by the connection member. | 06-16-2011 |
| 20120076594 | REINFORCED SELF-STANDING EARTH RETAINING STRUCTURE USING AN ARCHING EFFECT AND AN UNDERGROUND EXCAVATION CONSTRUCTION METHOD USING THE SAME - In a reinforced self-standing earth retaining structure using an arching effect, a soldier pile integrally formed with a soldier pile insertion portion in a vertical direction in a flange at one end of the soldier pile in which a lagging is inserted is installed at a width B to be perpendicular to the ground. A sheet panel protruding portion is inserted in and connected to the soldier pile insertion portion. A sheet panel protruding portion is serially inserted in a sheet panel insertion portion. A compression support plate protruding portion is inserted in and coupled to the sheet panel insertion portion. A relationship between a length L of a group of serial sheet panels and the width B between two groups of serial sheet panels is 0.5≦L/B≦3.0 in a range of an internal friction angle of earth φ=10˜34° and a range of an adhesive power C=0.0˜5.0 ton/m | 03-29-2012 |
| 20120087744 | Method Of Making A Polymer Sheet Piling Wall - A sheet piling wall includes a plurality of polymer corrugated sheet piles, such as vinyl sheet piles, connected together to form an corrugated wall structure having a front surface and a back surface. A plurality of blocks are adhesively secured to the back surface of the wall structure. Each block includes a fastener that is fastened to a bracket that is welded to a support bar extending horizontally behind the back surface. The support bar can be anchored to solid ground by use of tie back rods and an earth anchorage system. | 04-12-2012 |

| 20150093203 | PRE-CAST CONCRETE STRUCTURES - A system is taught comprising a first plain end concrete structure comprising two side faces extending horizontally to end in two end faces and a second fork end concrete structure comprising two side faces extending horizontally to end in two fork ends; said fork ends each comprising a pair of fork walls that define a slot. The system further comprises a base and a rigid support member embedded in the base, and received within said slot. The width of the slot of one or more of the fork ends at the mouth is sized to receive the end face of the plain end structure and the width of the slot increases from the mouth to the fork end face, and wherein the rigid support member is locked into the slot by the aggregate filler material. A system of stacked structures is taught, said system comprising one or more stacking structures, each comprising two side faces extending vertically to end in a bottom face and a top face, said top face comprising a top profile and said bottom face comprising a bottom profile. The one or more stacking structures are vertically stackable onto each other such that the top profile of a lower structure interfits with the bottom profile of a higher structure in the vertical stack. | 04-02-2015 |
