Description
Wasserdichte und schalldämpfende Isolierschichten für unter der Geländeoberkante liegende Ingenieurbauten aus Beton.Waterproof and sound-absorbing insulating layers for under the top of the terrain Recumbent engineering structures made of concrete.
Die vorliegende Erfindung betrifft wasserdichte und schalldämpfende Isolierschichten für unter der Geländeoberkante liegende Ingenieurbauten aus Beton, insbesondere für Tunnel.The present invention relates to waterproof and sound absorbing devices Insulating layers for civil engineering structures made of concrete below the ground level, especially for tunnels.
Die Abdichtung von z.B. Stahlbetonbauten, die vorab oder nach Fertigstellung unter der Geländeoberfläche liegen, erfolgte bisher gegen drückendes und nicht drückendes Wasser durch eine Aussenhautabdichtung, durch Verwendung von wasserdichtem Beton oder durch eine Innenhautabdichtung. Besonders üblich ist z.B. eine Außenhautabdichtung. Sie wird erstellt auf bituminöser oder Epoxydharz-Basis oder mittels thermoplastischer Kunststoff-Folien. Wo gen der zunehmenden Bedeutung des Umweltschutzes ist es aber häufig unumgänglich, von unterirdischen Betonbauten ausgehende Erschütterungen, Schwingungen und den Körperschall von einer benack barten Bebauung fernzuhalten. Dies geschah bisher durch mögliches Abfangen der Schwingungen bereits am Entstehungsort durch schwingungsdämpfende Aufhängungen von z.B. Maschinen gegenüber dem Bauwerk oder durch Dämpfungsmaßnahmen, z.B. einem Schotterunterbau unter Gleisen, elastisch aufgehängte Schwingungsplatten unter Gleisen oder Dämpfungsmatten unter einem Schotterbett.The sealing of reinforced concrete structures, for example, before or after completion lying beneath the surface of the terrain was previously carried out against oppressive and non-oppressive Water through an outer skin seal using waterproof concrete or by an inner skin seal. An outer skin seal, for example, is particularly common. It is created on a bituminous or epoxy resin basis or by means of thermoplastic Plastic foils. But it is against the increasing importance of environmental protection often unavoidable, vibrations emanating from underground concrete structures, Keeping vibrations and structure-borne noise away from neighboring buildings. Up to now, this has been done by intercepting the vibrations at the point of origin through vibration-damping suspensions of e.g. machines opposite the building or elastic by means of damping measures, e.g. a ballast substructure under tracks suspended vibration plates under rails or damping mats under a ballast bed.
Alle bisher bekannten Arbeitsweisen waren entweder sehr kostspielig oder sie reichten besonders bezüglich der Schalldämpfung nicht aus.All previously known ways of working were either very expensive or they were inadequate, especially with regard to sound absorption.
Der Erfindung liegt daher die Aufgabe zugrunde, eine in jeder Hinsicht wirksame Dämmschicht besser als bisher zeichen dem Erdreich bzw. den Verbauelementen der Baugrubenumschließungswände oder Unterfangungen einerseits und der Betonkonstruktion andererseits herzustellen. Wesentlich dabei ist die totale Abschirmung jeden Wassers, da keine Dämmschicht wirksam sein kann, wenn zwischen den zwei zu trennenden Medien, hier Betonbauwerk und Erdreich bzw. Verbauwand, Wasser eindringen kann.The invention is therefore based on the object of being one in all respects an effective insulation layer shows the soil and the building elements better than before the construction pit enclosing walls or underpinning on the one hand and the concrete structure on the other hand to manufacture. It is essential that all water is completely shielded, since no insulation layer can be effective if between the two media to be separated, here concrete structure and soil or retaining wall, water can penetrate.
Die vorliegende Erfindung löst die gestellte Aufgabe. Sie betrifft wasserdichte und schalldämpfende Isolierschichten für unter der Geländeoberkante liegende Ingenieurbauten aus Beton, insbesondere für Tunnel, welche dadurch gekennzeichnet sind, daß durch eine mehrere Zentimeter starke Schicht aus elastischen Eunststoff-Hartsonaumplat-ten oder biegsamen tiartschaumeinzellagen, die auf der einen Seite mit schlagzähen Hart-Folien aus tunststoff und auf der anderen Seite mit Weich-Folien aus Kunststoff wasserdicht abgedeckt ist.The present invention solves the problem posed. She concerns waterproof and sound-absorbing insulating layers for under the top of the terrain Horizontal engineering structures made of concrete, in particular for tunnels, which are characterized by this are that by a several centimeter thick layer of elastic plastic hard Sonaumplat-th or flexible tiart foam single layers, on one side with impact-resistant hard foils made of plastic and waterproof on the other side with soft plastic foils is covered.
Vorteilhaft sind die Isolierschichten so ausgebildet, daß über den Weich-Kunststoff-Folien eine nicht wasserdichte Schutzschicht aus schlagzähen Hart-Kunststoff-Folien liegt, die bei Verwendung an Seitenwänden des Bauwerks zur Ableitung von Sickerwasser ggf.The insulating layers are advantageously designed so that over the Soft plastic films a non-waterproof protective layer made of impact-resistant hard plastic films when used on the side walls of the structure for draining seepage water possibly.

Zweckmäßig ist der Kunststoff 3eVC, doch können naturgemäß auch andere Kunststoffe in Frage kommen, die gegen Verrottung genügend stabil sind.The plastic 3eVC is useful, but naturally others can also Plastics come into question that are sufficiently stable against rotting.
Bei einer bauweise ohne umgebenden Arbeitsraum gestaltet sich der Aufbau der Isolierschicht z.B. folgendermaßen: An einer vorbereiteten Verbauwand wird eine Schutzlage aus schlagzähem PVC, vornehmlich mit einseitigen Wülsten, diese Seite der Verbauwand zugekehrt, befestigt, um Unebenheiten zu überbrucken, eindringendes Sickerwasser abzuleiten und als Schutz gegen mechanische Verletzung der druckwasserhaltenden Abdichtungshaut. Auf die beschriebene Schutzlage wird eine wasserdruckhaltende Abdichtungshaut aus rvc weich mit Naht und Stoßüberdeckung verlegt, deren Nähte und Stöße wasserdicht und kraftschlüssig verschweißt werden. Dann wird unter die Abdichtungshaut ein Schaumstoff aus PVO hart verlegt, der unverrottbar ist und weder im drucklosen Zustand noch unter Druck seine Eigenschaften verändert und bei hoher Belastung von ca. 4 - 5 Ep/cm2 seine elastische Eigenschaft behält, um körperschaildämpfend - bzw.In the case of a design without a surrounding work space, the Structure of the insulating layer, for example, as follows: On a prepared sheeting wall is a protective layer made of impact-resistant PVC, primarily with one-sided beads, this Side facing the shoring wall, fastened to bridge unevenness, penetrating Discharge seepage water and as protection against mechanical damage to the pressurized water Waterproofing skin. A waterproofing waterproofing membrane is placed on the protective layer described Made of soft rvc laid with seam and joint cover, the seams and joints are waterproof and welded with a force fit. Then a foam is placed under the sealing skin made of PVO hard laid, which is rot-proof and neither in a depressurized state nor changes its properties under pressure and from approx. 4 - 5 under high loads Ep / cm2 retains its elastic properties in order to dampen the body
-dämmend zu wirken. Schließlich wird unter dem dichtungs- und schalldämpfenden Aufbau eine Schutzlage aus schlagzähem Hart-PVC verlegt mit Naht- und Stoßüberdeckung, deren Nähte und Stöße wasserdicht und kraftschlüssig verschweißt werden, um das aus dem Beton austretende überschüssige Anmachwasser von Schaumstoff fernzuhalten und um die schwingungsdämpfende Schicht vor Beschädigungen zu schützen.-to have an insulating effect. Finally, under the sealing and sound absorbing Structure of a protective layer made of impact-resistant hard PVC laid with seam and joint overlap, the seams and joints of which are welded watertight and force-fitting to ensure that the Keep excess mixing water escaping from the concrete away from the foam and to protect the vibration damping layer from damage.
Bei Bauweisen mit freiem Arbeitsraum wird der Aufbau in umgekehrter Richtung ausgeführt und bei Boden- und Deckenflächen spiegelbildlich.In the case of construction methods with free working space, the structure is reversed Direction and mirror image for floor and ceiling surfaces.
Die Stärke der verwendeten Schichten ist etwa folgende: Weichfolie 0,8 - 2 mm, Hartfolie mindestens 1,5 - 3 mm, vorzugsweise 2 mm, Schaumstofflage 2 - 6 cm, vorzusweise 5 cm.The thickness of the layers used is roughly as follows: Soft film 0.8 - 2 mm, rigid film at least 1.5 - 3 mm, preferably 2 mm, foam layer 2 - 6 cm, preferably 5 cm.
