摘要:
The bottom part of the bridge drainer consists of the tray (3). The outlet of the tray (3) is joined to the bridge draining system and the top rim of said tray (3) is shaped to form the collar (3C). On this collar (3C) the waterproofing (11) is located on which the set of the frame (2) with the grating (1) is laid. The grating (1) is joined with the frame (2) by means of the hinge (5) which is located so that the axial junction is perpendicular to the traffic direction on the bridge. The frame (2) has a circular opening in itself on the circumference of which the limiting lugs (10) are made to limit the rotational rectification, said limiting lugs (10) having the shape of opposite located sectors, rotated by 45° against the vertical axis of said frame (2). The bottom part of said frame (2) is provided with the grooves (9) to drain off the surface of the waterproofing (11) of the bridge. If needed, the drainer system can be modified, during assembling, for diverse thicknesses of the bridge floor layer set by relevant combination of dimensional variants of the rectification rings (4), inserted between the waterproofing (11) and said frame (2). According to the requirement on the water outlet direction, the tray (3) with the vertical outlet (3A) or the tray (3) with the side outlet (3B) can be used.

Die Erfindung betrifft eine Haltekonstruktion für Fahrbahndecken, die einen Beton-oder Stahlunterbau und eine Asphaltdeckschicht aufweisen. Dabei ist auf dem Unterbau ein Stahlblech definierter Größe punktuell nach einem vorgegebenen Raster verankert und mit dem Stahlblech ist eine Verankerungsauflage scherfest verbunden, auf die der die Deckschicht bildende Asphalt aufbringbar ist.
摘要:
A geocomposite system (10,40) for increasing the service life of roads, bridges, or the like, includes a geocomposite layer (12,42) having a geomembrane (18,60) disposed between two geotextile backings (20,22,56,58), a structural layer (14,44) for supporting the geocomposite layer (12,42), and a base layer (16,46) formed on top of the geocomposite layer (12,42). The geomembrane (18,60) is impermeable and the geotextile backings (20,22,56,58) are sufficiently porous to provide a wicking action of moisture or liquid laterally along the geomembrane (18,60) and out of the geocomposite system (10,40) to prevent moisture or liquid damage. The geomembrane (18,60) prevents the intrusion of liquids including deicing salts into the structural layers of roads, bridges, or the like abating deterioration in the structural layers such as corrosion of reinforcing steel. The geocomposite layer (12,42) is bonded to and conforms to the structural layer (14,44), thus reducing reflective, shrinkage and fatigue cracking and increasing the structural capacity of the road or bridge. Preferably, the geomembrane (18,60) is an extruded polyvinylchloride web and the geotextile backings (20,22,56,58) are fabricated of a mat of non-woven polyester fibers. The geotextile backings (20,22,56,58) are heat coupled to the geomembrane (18,60), preferably using a calendaring process. The geocomposite layer (12,42) is also bonded to the base layer (16,46). In the related method, the geocomposite system is constructed by fabricating the geocomposite layer, applying a tack coat to the structural layer, placing the geocomposite layer with the geotextile backing down on the prepared structural layer, rolling the geocomposite to provide conformity with the structural layer, applying a tack coat to the other geotextile backing and forming and bonding the base layer on the geocomposite layer.
摘要:
A method for covering the interface between a bridge abutment and a bridge in a road with a surface material, comprises the steps of:
providing an asphaltic mixture having high porosity and composed of small stone fragments (1) and bitumen (2), applying the apshaltic mixture at least at the interface, filling the pores or open cavities in the asphaltic mixture with a curable elastic plastics compound (3), curing the plastics compound.
摘要:
An exemplary waterproofing membrane comprises a carrier layer having a non-bituminous pressure-sensitive waterproofing adhesive, a protective layer coated on the non-bituminous adhesive, and a second waterproofing adhesive layer on the other face of the carrier to permit adherence of the membrane to a cementious surface and to permit concrete to be cast against the non-bituminous layer and protective coating and to be bonded thereto when cured. Further exemplary membranes comprise a dusted layer on the protective coating to permit foot traffic. The membranes of the invention are useful in so-called horizontal and vertical lagging installations. Methods for waterproofing between cementious surfaces, in tunnels, and on concrete decks are also disclosed.
