Abstract

The invention relates to the making or the renewing of vertical seals in underground constructions to protect against earth moisture. The object of the invention is to design the seal to be more economical and more reliable in operation and thus to avoid digging up the earth. In the process according to the invention, wedge-shaped elements are driven into the ground directly at the masonry surface down to the foundation base. The crack-shaped clearance space which develops between masonry and ground is then filled with a preferably liquid sealing material. An apparatus according to the invention consists of a block-like element with wedge-shaped profile. Arranged within the bottom wedge surface is at least one part which can be released in the perpendicular direction and acts as a wedge valve. In this stop, this wedge valve seals off a filling tube located in the block-like element. The wedge valve is locked on the top edge of the block-like element via a lowering rod running through the filling tube. The filling tube is sealed off at the top end by a cover disc and a closure cap. In the top part of the block-like element, a lateral inflow opening is located in the filling tube. The block-like wedge-shaped element is driven in at the masonry side into the ground down to the foundation base. During withdrawal, sealing material is fed under pressure into the clearance space. By lowering the releasable wedge valve, the seal of the filling tube is opened and an initial opening is created for the sealing material. <IMAGE>

Description

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur nach­träglichen Herstellung bzw. Erneuerung von vertikalen Dichtungen an Bauwerken unterhalb Terrain gegen Erdfeuchtigkeit. Anwendbar ist die Erfindung bei allen Bauwerken des Wohnungs-, Gesellschafts- und In­dustriebaues, Denkmälern usw.The invention relates to a method and a device for the subsequent production or renewal of vertical seals on structures below ground against earth moisture. The invention is applicable to all structures of residential, social and industrial buildings, monuments, etc.

Entsprechend bautechnischer Forderungen und gültiger Standards sind Bauwerke grundsätzlich gegen Erdfeuchtigkeit u.a. durch vertikale Abdichtungen zu schützen. Nach dem Stand der Technik wird der nach­trägliche vertikale Feuchteschutz eines Gebäudes überwiegend nach Freilegen des Grundmauerwerkes bis zur Fundamentsohle praktiziert, damit eine den bautechnischen Forderungen entsprechende vertikale Schutzschicht aus Anstrichen, Beschichtungen, Bahnen, Folien, minera­lischen Dichtungsmaterialien u.a. ausgeführt werden kann. Dieser Erd­aushub, insbesondere für den nachträglichen vertikalen Feuchtigkeits­schutz, ist mit hohem technisch-technologischem bzw. manuellem sowie ökonomischem Aufwand verbunden. Einschränkungen können sich durch bauwerksbedingte Gegebenheiten, wie z.B. durch die Oberflächengestal­tung des umgebenden Terrains, Bebauungsdichte und -art, unterirdi­sche Versorgungsleitungen, Bauwerke u.dgl. ergeben. Wird aus vorge­nannten Gründen auf die Herstellung eines funktionstüchtigen Abdich­tungssystems verzichtet, hat das für die weitere Nutzung und den Be­stand des Bauwerkes erheblich negative Auswirkungen.In accordance with construction requirements and applicable standards, buildings are fundamentally protected against moisture, among other things. to protect with vertical seals. According to the state of the art, the subsequent vertical moisture protection of a building is mainly practiced after exposing the basic masonry to the base of the foundation, so that a vertical protective layer made of paints, coatings, sheets, foils, mineral sealing materials etc. meets the structural requirements. can be executed. This excavation, especially for the subsequent vertical moisture protection, is associated with high technical, technological, manual and economic expenditure. Restrictions can arise due to building-related conditions, such as due to the surface design of the surrounding terrain, density and type of building, underground supply lines, buildings and the like. surrender. If, for the reasons mentioned above, the production of a functional sealing system is dispensed with, this has a considerably negative impact on the further use and the existence of the building.

Für die Herstellung von Abdichtungen an Mauerwerksoberflächen existie­ren mehrere Varianten, die jedoch bei Mauerwerk unter Terrain in der Regel eine Aufschachtung erfordern. Nach der DD-PS 100 991 werden Kunststoffe auf das zuvor erhitzte Mauerwerk aufgepreßt, wozu eine verfahrbare Vorrichtung eingesetzt werden kann. Desgleichen wird in der DD-PS 252 097 ein Dichtungsschutz für unterirdische Bauwerke unter Schutz gestellt, der aus mehreren Schichten besteht und in aufwendi­ger Technologie zwischen Mauerwerk und Erdreich eingebracht wird.There are several variants for the production of seals on masonry surfaces, but these generally require excavation for masonry under terrain. According to DD-PS 100 991, plastics are pressed onto the previously heated masonry, for which purpose a movable device can be used. Similarly, in DD-PS 252 097 a seal protection for underground structures is protected, which consists of several layers and is inserted between masonry and soil using complex technology.

Nach der DD-PS 254 042 wird ein vertikaler Schutz des Kellermauerwer­kes durch Anordnung von Belüftungsschächten errreicht. Große Nachteile entstehen hier noch zusätzlich durch Frostschäden, da die Kälte unge­hindert in das Mauerwerk eindringen kann. Weiterhin bildet sich bei ungenügender Luftzirkulation Kondenswasser, wodurch eine weitere Durchfeuchtung des Mauerwerkes verursacht wird.According to DD-PS 254 042, vertical protection of the basement masonry is achieved by arranging ventilation shafts. There are also major disadvantages due to frost damage, since the cold can penetrate the masonry unhindered. In addition, if there is insufficient air circulation, condensation forms, which causes further dampening of the masonry.

In der AT-PS 377 811 wird ein Verfahren zur Trockenlegung unterirdi­scher Teile von Bauwerken ohne Aufschachtung des Erdreiches beschrie­ben, bei welchem ein flüssiges oder teigiges und später erhärtendes Injektionsgut als feuchtigkeitsdichtende Schutzschicht wirkt. Das Injektionsgut wird dabei über senkrechte Bohrungen in den Erdboden an der Außenseite des Gebäudes oder über waagerechte Durchbohrungen des Grundmauerwerkes vom Keller aus in das anliegende Erdreich gedrückt. Infolge unterschiedlicher Bodenstrukturen und der damit verbundenen unkontrollierbaren Verteilung des Injektionsgutes ist die Herstellung einer durchgängig funktionstüchtigen und effektiven Schutzschicht nicht möglich.AT-PS 377 811 describes a process for draining underground parts of buildings without excavation of the ground, in which a liquid or pasty and later hardening grout acts as a moisture-proof protective layer. The grout is pressed through vertical holes in the ground on the outside of the building or through horizontal holes in the basic masonry from the basement into the surrounding soil. As a result of different floor structures and the associated uncontrollable distribution of the injection material, it is not possible to produce a fully functional and effective protective layer.

Ziel der Erfindung ist es, an vorhandenen Bauwerken vertikale Abdich­tungen gegen Erdfeuchtigkeit unterhalb Terrain ohne hohen Aufwand zu schaffen. Die Abdichtung soll dabei von hoher Qualität und Lebens­dauer sein.The aim of the invention is to create vertical seals against earth moisture below terrain on existing structures without great effort. The seal should be of high quality and durability.

Es ist Aufgabe der Erfindung, vorhandenes Mauerwerk unterhalb Terrain gleichmäßig und funktionssicher abzudichten, ohne eine Aufschachtung des Erdreiches vorzunehmen.It is an object of the invention to seal existing masonry underneath terrain evenly and reliably, without having to excavate the ground.

Erfindungsgemäß wird die Aufgabe durch ein Verfahren gelöst, wonach ein oder mehrere keilförmige Elemente nacheinander unmittelbar an der Mauerwerksoberfläche bis zur Fundamentsohle durch Schlag- bzw. Schwingungseinwirkung in das Erdreich eingetrieben werden. Diese Ele­mente werden anschließend mit einer an sich bekannten Spreizvorrich­tung, einer Spindel, einem Keil und sonstige pneumatische oder hydrau­lische Vorrichtungen von der Wand leicht abgedrückt, sodaß ein spalt­förmiger Freiraum zwischen Wand und Erdreich geschaffen wird. In die­ sen Freiraum werden danach zur Schaffung einer Vertikaldichtung an sich bekannte Dichtmaterialien eingebracht, vorzugsweise flüssige oder plastische, feuchteabweisende Substanzen auf Bitumen-, Kunst­stoff- und Mineralbasis. Es sind auch Platten und Folien möglich. Die Form und Größe des Freiraumes lassen sich durch Herstellen eines Drehpunktes, z.B. in der Mitte des keilförmigen Elementes durch He­belwirkung in Richtung der Wand und in Abhängigkeit von der vorgese­henen Abdichtungsvariante optimal gestalten. Nach Fertigstellung der Abdichtung werden die keilförmigen Elemente mittels bekannter Hubvor­richtungen aus dem Erdreich herausgezogen. Der verbleibende Hohlraum kann mit einer abdichtenden Suspension zusatzlich verfüllt werden, sodaß gleichzeitig ein wirksamer Schutz für die eingebrachte Abdich­tung entsteht.According to the invention, the object is achieved by a method according to which one or more wedge-shaped elements are driven one after the other directly on the masonry surface to the base of the foundation by impact or vibration in the ground. These elements are then slightly pushed off the wall with a spreading device known per se, a spindle, a wedge and other pneumatic or hydraulic devices, so that a gap-shaped free space is created between the wall and the ground. In the Sen free space is then introduced to create a vertical seal known sealing materials, preferably liquid or plastic, moisture-repellent substances based on bitumen, plastic and mineral. Sheets and foils are also possible. The shape and size of the free space can be optimally designed by establishing a fulcrum, for example in the middle of the wedge-shaped element, by lever action in the direction of the wall and depending on the sealing variant provided. After completion of the sealing, the wedge-shaped elements are pulled out of the ground by means of known lifting devices. The remaining cavity can additionally be filled with a sealing suspension, so that at the same time effective protection is created for the sealing introduced.

Die Aufgabe wird weiterhin durch eine Vorrichtung gelöst, die aus einem blockähnlichen Element besteht, das im Profil keilförmig ausge­bildet ist. Innerhalb der unteren Keilfläche ist mindestens ein in senkrechter Richtung bewegbares, herauslösbares ventilartiges Teil­stück angeordnet, welches im oberen Anschlag im blockähnlichen Ele­ment befindliches Füllrohr abdichtet.The object is further achieved by a device which consists of a block-like element which is wedge-shaped in profile. Arranged within the lower wedge surface is at least one valve-like section which can be moved out in the vertical direction and which seals off the filling tube located in the upper stop in the block-like element.

Das ventilartige Teilstück ist über eine durch das Füllrohr verlau­fende Absenkstange an der Oberkante des blockähnlichen Elementes ar­retiert. Das Füllrohr kann am oberen Ende mit einer Abdeckscheibe verbunden sein, die fest auf dem blockähnlichen Element aufliegt und durch eine darüber befindliche Verschlußkappe abgedichtet und fest­gedrückt ist. Im oberen Teil des blockähnlichen Elementes kann eine Zuflußöffnung zum Füllrohr seitlich angeordnet sein. Das herauslös­bare Teilstück kann schräge Seitenflächen aufweisen, die parallel zum Ausschnitt aus dem blockähnlichen Element verlaufen. Die erfin­dungsgemäße Vorrichtung arbeitet wie folgt:
Das blockähnliche, keilförmige Element wird an der Mauerseite in das Erdreich eingetrieben, meistens bis zur Fundamentsohle eines Gebäu­des. Beim Zurückziehen des Keilelementes wird gleichzeitig unter Druck Dichtungsmaterial in den entstandenen Freiraum eingebracht. Dies wird dadurch erreicht, indem durch Absenkung des herauslösbaren ventilartigen Teilstückes aus dem blockähnlichen Element die Abdich­tung des Füllrohres geöffnet und so eine Austrittsöffnung für die einzubringenden Materialien geschaffen wird.The valve-like section is locked via a lowering rod running through the filling pipe at the upper edge of the block-like element. The filler tube can be connected at the upper end to a cover plate which rests firmly on the block-like element and is sealed and pressed in by a closure cap located above it. In the upper part of the block-like element, an inflow opening to the filling pipe can be arranged laterally. The detachable section can have inclined side surfaces that run parallel to the cutout from the block-like element. The device according to the invention works as follows:
The block-like, wedge-shaped element is driven into the ground on the side of the wall, mostly up to the base of a building. When pulling back the wedge element, sealing material is simultaneously introduced into the free space under pressure. This is achieved by lowering the detachable valve-like section from the block-like element opens the seal of the filling tube and thus an outlet opening is created for the materials to be introduced.

Die Erfindung hat den Vorteil, daß qualitätsgerechte, durchgängig funktionstüchtige Abdichtungen an Gebäudeoberflächen unter Terrain hergestellt werden ohne aufwendige Aufschachtungsarbeiten. Die Her­stellung der vertikalen Abdichtung wird mit einer einfach zu handha­benden kostengünstigen Vorrichtung erreicht. Mit dieser Vorrichtung sind auch spezielle Abdichtungsaufgaben außerhalb von Gebäuden ohne Erdaushub ökonomisch lösbar, wie z.B. das Herstellen von wasserdich­ten Blenden und Schürzen im Erdreich.The invention has the advantage that high-quality, consistently functional seals are made on building surfaces under terrain without complex excavation work. The production of the vertical seal is achieved with an easy-to-use, inexpensive device. With this device, special sealing tasks outside of buildings without excavation can be solved economically, e.g. the manufacture of waterproof screens and aprons in the ground.

Die Erfindung wird an einem Ausführungsbeispiel näher erläutert. Die Zeichnungen zeigen: Fig. 1 die Darstellung des keilförmigen Elementes des Verfahrens in Seitenansicht, Fig. 2 die Darstellung der Vorrich­tung in Isometrie, Fig. 3 einen Schnitt A-A aus Fig. 2, Fig. 4 das herauslösbare, ventilartige Teilstück im oberen Anschlag, Fig. 5 das herauslösbare, ventilartige Teilstück im unteren Anschlag.The invention is explained in more detail using an exemplary embodiment. The drawings show: FIG. 1 the side view of the wedge-shaped element of the method, FIG. 2 the isometric view of the device, FIG. 3 a section AA from FIG. 2, FIG. 4 the detachable, valve-like section in the upper stop, Fig. 5, the detachable, valve-like section in the lower stop.

An einem 70 Jahre alten Wohnhaus ist Erdfeuchtigkeit in das Grund­mauerwerk eingedrungen. Durch Bauzustandsanalyse wird die Funktions­tüchtigkeit der bituminösen Vertikalabdichtung festgestellt. Eine Erneuerung der Vertikalabdichtung nach dem bisherigen Stand der Tech­nik wäre objektbedingt nur durch manuelle Aufschachtung bis ca. 1,5 m Tiefe mit erheblichem Aufwand möglich.Moisture has penetrated the foundation brickwork of a 70-year-old house. The functionality of the bituminous vertical seal is determined by analyzing the condition of the building. A renewal of the vertical sealing according to the current state of the art would only be possible with considerable effort, due to the object, by manual excavation to a depth of approx.

Nach dem erfindungsgemäßen Verfahren wird gemäß Fig. 1 folgendermaßen vorgegangen:
Abschnittweise wurden 4 Stück 1,50 m lange und 0,50 m breite keilför­mige Elemente 3 mittels aufgesetztem Druckluft-Schlaghammer unmittel­bar an der Gebäudeaußenwand 1 in das Erdreich 4 getrieben. Mittels angebrachter mechanischer Spindeln wird ein oberer Freiraum von ca. cm geschaffen. Nach Fixierung der keilförmigen Elemente 3 im oberen Bereich durch Abstandshalterungen 7 werden mittels Schlaghammer Keile eingetrieben, die den unteren Freiraum auf ca. 2 cm vergrößern. In den so entstandenen Hohlraum wird wegen des bereits vorhandenen bi­tuminösen Untergrundes ein großflächiges Bitumen-Latex-Gemisch einge­bracht. Nach der Verfestigung erfolgt das Herausziehen der Keilele­mente 3 mittels Seilrolle. In den verbliebenen Hohlraum wird an­schließend Feinsand eingeschlämmt.The procedure according to the invention according to FIG. 1 is as follows:
In sections, 4 pieces 1.50 m long and 0.50 m wide wedge-shaped elements 3 were driven into the soil 4 directly on the outer wall 1 of the building by means of a pneumatic hammer. An upper clearance of approx. Cm is created by means of attached mechanical spindles. After fixing the wedge-shaped elements 3 in the upper area by means of spacers 7, wedges are driven in using a hammer, which increase the lower free space to approximately 2 cm. In A large-scale bitumen-latex mixture is introduced into the resulting cavity due to the bituminous substrate already present. After the consolidation, the wedge elements 3 are pulled out by means of a pulley. Fine sand is then slurried into the remaining cavity.

Die erfindungsgemaße Vorrichtung ist nach den Fig. 2 bis 6 wie folgt aufgebaut:
In dem keilförmigen, blockähnlichen Element 12 befindet sich in ver­tikaler Richtung ein durchgehendes Füllrohr 8 für flüssiges Dichtma­terial. Im unteren Teil des blockähnlichen Elementes 12 wird das Füll­rohr 8 durch das aus dem Element 12 herauslösbare ventilartige Teil­stück 9 verschlossen. Das Teilstück 9 weist in der Vorderansicht schrä­ge Seitenflächen auf, die parallel zum Ausschnitt aus dem Element 12 verlaufen. Über die starre Verbindung mit der Absenkstange 10 ist das Teilstück 9 an der Oberkante des blockähnlichen Elementes 12 ar­retiert. Dies geschieht durch eine am oberen Ende der Absenkstange 10 befindliche Abdeckscheibe 13, die auf dem Element 12 dicht aufhängt und so auch den Austritt von Dichtflüssigkeit verhindert. Zur weite­ren Abdichtung und zum Festdrücken ist über der Abdeckscheibe 13 eine Verschlußkappe 14 angeordnet. Im oberen Teil des blockähnlichen Ele­mentes 12 befindet sich auf der Flachseite eine Zuflußöffnung 11 zum Füllrohr 8. Das blockähnliche Element 12 wird dicht an der Gebäude­außenwand 1 in das Erdreich 4 eingetrieben bis zur Fundamentsohle 2 des Gebäudes. Nun wird das Teilstück 9, das als Keilventil wirkt, aus dem unteren Teil des Elementes 12 herausgelöst und nach unten geschoben. Dadurch wird das Füllrohr 8 geöffnet. Unter Druck fließt nun das Dichtmaterial aus dem Füllrohr 8 über die Gebäudeaußenwand­fläche 1. Aufgrund der schrägen Seitenflächen des Teilstückes 9 ver­teilt sich das Dichtmaterial gleichmäßig über die Gebäudeaußenwand 1. Durch das Teilstück 9 wird beim Herauslösen aus dem blockähnlichen Element 12 vorgelagertes Erdreich 4 beseitigt, und so eine Verstopfung des Füllrohres 8 vermieden. Ein Austritt des Dichtmaterials aus dem Füllrohr 8 über die Oberkante des Elementes 12 hinaus wird durch die Abdeckscheibe 13 mit Verschlußkappe 14 vermieden. Weitere Dichtflüs­sigkeit wird durch die Zuflußöffnung 11 nachgefüllt.The device according to the invention is constructed as follows according to FIGS. 2 to 6:
In the wedge-shaped, block-like element 12 there is a continuous filling tube 8 for liquid sealing material in the vertical direction. In the lower part of the block-like element 12, the filling tube 8 is closed by the valve-like section 9 which can be removed from the element 12. The section 9 has oblique side surfaces in the front view, which run parallel to the section of the element 12. Via the rigid connection to the lowering rod 10, the section 9 is locked at the upper edge of the block-like element 12. This is done by a cover plate 13 located at the upper end of the lowering rod 10, which hangs tightly on the element 12 and thus also prevents the leakage of sealing liquid. For further sealing and for pressing a closure cap 14 is arranged over the cover plate 13. In the upper part of the block-like element 12 there is an inflow opening 11 to the filling pipe 8 on the flat side. The block-like element 12 is driven into the soil 4 close to the outer wall 1 of the building up to the base 2 of the building. Now the section 9, which acts as a wedge valve, is detached from the lower part of the element 12 and pushed down. As a result, the filling pipe 8 is opened. Under pressure, the sealing material now flows from the filling pipe 8 over the building outer wall surface 1. Because of the sloping side surfaces of the section 9, the sealing material is distributed evenly over the building outer wall 1. By removing the section 9, soil 4 upstream from the block-like element 12 is removed, and so a blockage of the filling tube 8 avoided. An escape of the sealing material from the filling tube 8 beyond the upper edge of the element 12 is prevented by the cover plate 13 with the closure cap 14. Additional sealing liquid is refilled through the inflow opening 11.
