摘要:
An apparatus for detecting a connection between adjacent vertical panels having a first contact element (122) positioned adjacent a bottom of one of the panels, a second contact element (128) positioned adjacent a bottom of an adjacent panel, a first conductive line (132) extending from the first contact element (122), a second conductive line (134) extending from the second contact element (128), an electrical source for passing a current to at least one of the first and second conductive lines, and a detector (152) connected to one of the first and second conductive lines for ascertaining the existence of a connection between the first contact element (122) and the second contact element (128). The second contact element (128) is positioned in proximity to the first contact element (122) when the panels are connected together. The first contact element (122) is affixed to a connector of the panel. The second contact element (128) is affixed to an interlocking member (130) of an adjacent panel. The connector (124) is a T-shaped member extending outwardly from a surface of the panel. The interlocking member (130) is a channel formed in the adjacent panel. The T-shaped member is slidably received within the channel.

Die Erfindung betrifft eine in einen Untergrund (1) eingebrachte Schmalwand oder Schlitzwand (2) mit einer darin befindlichen Dichtwandmasse (3) und wenigstens einer Dichtwandscheibe (4), z.B. aus Glas, wobei zur Lösung der Aufgabe, mit einfachen und zuverlässigen Mitteln eine Überwachung und Überprüfung von solchen Wänden auf Durchlässigkeiten zu schaffen, die Dichtwandscheibe (4) bzw. -scheiben Vorrichtungen zur Erkennung von Leckagen besitzt bzw. besitzen.
摘要:
Nach der Erfindung wird eine nachträgliche Abdichtung unter vorhandene Deponien und/oder kontaminierte Flächen dadurch erreicht, daß Profilstränge nacheinander unter die Deponie bzw. die kontaminierte Fläche gezogen oder geschoben werden, die sich dabei zu einer Abdichtung miteinander verbinden.

Nach der Erfindung wird die notwendige Dicke für Schlitzwände im Tief- und Tunnelbau wesentlich verringert, wenn zunäscht eine thixotrope Masse in die ausgehobenen Erdschlitze eingebracht und danach Dichtungselemente aus Kunststoffdichtungsbahnen mit aufgebrachtem Ortbeton in die thixotrope Masse abgesenkt werden.
摘要:
A thermoplastic curtain wall system is provided for forming a vertical curtain wall (10) from a plurality of wall sections (20). Each of the wall sections includes a rectangular thermoplastic panel (20) to which at least one locking strip (22) is fused to. The locking strip (22) is formed with two generally dovetail shaped locking members (30A,30B), a channel (33) and a locking lip (38). In joining two of the wall sections (20), the locking strips (22) of adjoining wall sections (20) are homogamously interlocked to form connecting joints. Spaces are defined in the joint for accommodating sealant material.

Nach der Erfindung werden Schweißpatronen (6), mit denen Randprofile von Kunststoffabdichtungsbahnen (1, 2) in Erdschlitzen miteinander verschweißt werden, mit Flügeln (9) versehen, die in die Dichtfugen der Randprofile ragen und die Dichtflächen sauber räumen, so daß ein mit einer nachlaufenden Verdickung (8) erzeugter Materialpfropfen eine gute Verschweißung herbeiführen kann.
摘要:
High density polyethylene sheets are installed in panel forms to form an impervious barrier to fluid flow particularly corrosive contaminates and pollutants. A slit is excavated in the earth under the bentonite slurry to the required depth. A relatively thick, high density polyethylene sheet (12) is placed in the trench and connected to two high density polyethylene pipes or channel members (10, 11), the width of which, in the direction transverse to the direction of the wall, is the width of the trench. The panel length typically will be 15 to 30 feet. Once the high density polyethylene panel is installed, the slurry is displaced on both sides of a backfill material that can be soil-bentonite, cement-bentonite or concrete. A secondary panel section intermediate two previously formed primary panels is made using a secondary panel (22) of high density polyethylene similarly constructed but using smaller diameter pipe or channel members (26, 27) than the primary panel pipes. This panel is then lifted and the two smaller pipes or channels lowered into the primary panel pipes or channels with the high density polyethylene panel extending between through two slots or openings (30, 31) in facing primary panel pipe or channel elements. A non-shrinking grout (60) is then pumped into the pipe connection to form a tight joint.
