摘要:
A modular bund system comprising two or more wall components connectable together to form a perimeter around an area to be protected. Each component has a longitudinal slot or channel extending internally along its length to receive a sealing member. The sealing member is located within the slot to provide a fluid barrier along the base of each the component.

The invention relates to a refuse landfill impervious system capable of prolonging breakdown time of leachate and a manufacturing method thereof. The system comprises a leachate collection and drainage layer, a first HDPE (high-density polyethylene) geomembrane impervious layer, a clay layer and a groundwater collection and drainage layer which are sequentially stacked from top to bottom. The clay layer is composed of a lower clay layer, a middle clay layer and an upper clay layer which are sequentially arranged, wherein the middle clay layer is filled with a medium-fine sand layer laid with sands of particle sizes ranging from 0.1 mm to 0.5 mm and of water contents ‰¤ 3%, wherein the saturated permeability coefficient of the medium-fine sand layer varies from 1×10 -5 to 1×10 -3 cm/s. Therefore, breakdown time of the leachate can be greatly prolonged, and the imperious effects of a refuse landfill impervious layer can be enhanced; meanwhile, the medium-fine sands are readily available as they are low in cost and widely spread in China. The refuse landfill impervious system capable of prolonging breakdown time of the leachate has a simple structure and is able to effectively prevent the groundwater from permeating in order to saturate the medium-fine sand layer, keeping the medium-fine sand layer in an unsaturated state all the time.

The present invention relates to an outdoor tank waterproofing sheet for covering the boundary region between the bottom of an outdoor tank, which is disposed on a base, and said base in a light-tight manner by spanning and adhering from the outdoor tank to the base, the sheet being characterized in being obtained from a single flexible elastomer layer. The present invention provides an outdoor tank waterproofing sheet and outdoor tank waterproofing method effective for preventing the infiltration of rainwater into the boundary region between the bottom of an outdoor tank, particularly a large tank that is often placed mainly at oil refineries, etc., and a base.
摘要:
Die Erfindung betrifft ein Verfahren zur Vereisung einer Erdbodenmasse sowie eine Einrichtung zur Durchführung des Verfahrens. Bei der erfindungsgemäßen Vereisung einer Erdbodenmasse (100) wird mittels flüssigen Stickstoffs (61) ein Kältemedium (12) gekühlt und mittels des Kältemediums (12) ein Kälteträger (22) gekühlt, wobei der Kälteträger (22) über Wärmeaustausch mit der Erdbodenmasse (100) dieser Wärme entzieht. Zu diesem Zweck ist ein Primär-Fluidsystem (10) zur Aufnahme eines Kältemediums (12) und ein mittels eines ersten Wärmeübertragers (30) mit dem Primär-Fluidsystem (10) verbundenes Sekundär-Fluidsystem (20) zur Aufnahme eines Kälteträgers (22) vorgesehen, der zum Wärmeaustausch mit der Erdbodenmasse (100) eingerichtet ist. Im Primär-Fluidsystem (10) ist ein zweiter Wärmeübertrager (40) angeordnet, mit dem Kälte von flüssigem Stickstoff (61) auf das Kältemedium (12) im Primär-Fluidsystem (10) übertragbar ist.

The invention relates to a method for producing a multilayer sealing structure (1) from asphalt sheets (2) comprising an electrically conductive inner layer. For this purpose, asphalt sheets are used, each of which is provided at the factory with an electrically conductive coating (3), which ends with clearance from at least one of the longitudinal edges (2.1, 2.3) and at least one of the transverse edges (2.2, 2.4) of the asphalt sheet or is detachably glued to the asphalt sheet (2), wherein at least one transverse edge (3.2) of the coating (3) detachably glued to the asphalt sheet (2) is removed at the installation site of the asphalt sheets (2), such that the respective asphalt sheet (2) comprises non-conductive edge strips (2.5) as an overlapping and joining region for adjacent asphalt sheets that are to be disposed in the same sealing layer. The conductive coatings (3) of the asphalt sheets (2) forming the lower sealing layer are electrically connected by applying the asphalt sheets, which form the upper sealing layer located on top of same, onto the lower sealing layer such that the conductive coatings (3) of the upper asphalt sheets (2) face the lower sealing layer and are disposed longitudinally and/or transversely offset relative to the lower asphalt sheets so far that the conductive coatings (3) of the respective upper asphalt sheets cover the joining seams of the lower asphalt sheets, whereby an electrically conductive layer is created within the sealing structure that is substantially electrically conductive over the entire surface. The invention further relates to asphalt sheets (2) for producing such a sealing structure (1).
