Description

Die Erfindung betrifft ein Verfahren zum Abfangen von Stützmauern mit dahinter anstehendem Erdreich durch nachträgliche Anbringung von im Abstand zueinander angeordneten, sich im wesentlichen senkrecht zur Stützmauer erstreckenden Verstärkungsrippen, wie aus der AT-B-217 676 bekannt.The invention relates to a method for intercepting retaining walls with the soil behind them by subsequent attachment of spaced-apart reinforcement ribs which extend essentially perpendicular to the retaining wall, as is known from AT-B-217 676.

Es ist bereits seit sehr langer Zeit bekannt, Stützmauern, hinter denen Erdreich ansteht, durch als Stützpfeiler oder Pfeiler-Vorlagen ausgebildete Verstärkungsrippen zu stützen, die an der Mauervorderseite, d.h. der dem Erdreich abgekehrten Seite, in Abständen angebracht werden. Obwohl die Festigkeit einer solchen Stützmauer mit davorstehenden Verstärkungsrippen statisch nicht nachweisbar ist, haben die über Jahrhunderte reichenden Erfahrungen gezeigt, daß auf diese Weise eine sehr wesentliche Stützwirkung erreicht wird. Die Anbringung derartiger Stützpfeiler vor der Mauer ist deshalb eine bereits sehr alte Maßnahme, um Stützmauern abzufangen, die sich wegen nicht ausreichender Schwergewichtswirkung zur Vorderseite hin neigen.It has been known for a very long time to support retaining walls, behind which there is soil, by means of reinforcing ribs designed as supporting pillars or pillar templates, which ribs on the front side of the wall, i.e. the side facing away from the ground, be placed at intervals. Although the strength of such a retaining wall with reinforcing ribs in front of it cannot be demonstrated statically, experience over centuries has shown that a very essential supporting effect is achieved in this way. The installation of such pillars in front of the wall is therefore a very old measure to intercept retaining walls that lean towards the front due to insufficient heavy weight effects.

Nachteilig an dieser Maßnahme ist, daß die die Stützpfeiler bildenden Verstärkungsrippen an der Mauervorderseite oftmals stören. Einerseits wird Platz beansprucht, der oftmals dort nicht zur Verfügung steht, weil an der Stützmauer Wege oder Strassen entlangführen; andererseits wird das Aussehen der Stützmauer durch die Stützpfeiler wesentlich verändert.A disadvantage of this measure is that the reinforcing ribs forming the supporting pillars on the front of the wall often interfere. On the one hand, space is required, which is often not available there because paths or roads lead along the retaining wall; on the other hand, the appearance of the retaining wall is significantly changed by the supporting pillars.

Deshalb wurden andere Maßnahmen zur Sanierung von Stützmauern entwickelt. Bei einem bekannten Verfahren (DE-OS 34 o8 461) wird entlang der gesamten Stützmauer an der Mauerrückseite ein Hohlraum durch Ausspülen erzeugt, der anschließend durch Einpressen einer Mörtelmasse verfüllt wird, die nach dem Abbinden einen mit der Stützmauer zusammenhängenden Mauerwerkskörper bildet, der eine vollständige Schwergewichtsmauer darstellt, deren Standfestigkeit auch statisch nachweisbar ist.Therefore, other measures for the renovation of retaining walls were developed. In a known method (DE-OS 34 o8 461), a cavity is created along the entire retaining wall on the back of the wall by rinsing, which is then filled in by pressing in a mortar mass which, after setting, forms a masonry body connected to the retaining wall, which is complete Heavyweight wall, the stability of which is also statically verifiable.

Der hierfür erforderliche Aufwand an Arbeit und an Mörtelmasse ist verhältnismäßig groß und vollzieht sich allein nach dem Prinzip der Schwergewichtsmauer. In vielen Fällen reicht es auch aus, einzelne im Abstand angeordnete Verstärkungsrippen an der Mauervorderseite vorzusehen, wie die zahlreichen und teilweise sehr alten Beispiele von Stützmauern zeigen.The work and mortar mass required for this is relatively large and takes place solely on the principle of the heavyweight wall. In many cases it is also sufficient to provide individual, spaced-apart reinforcement ribs on the front of the wall, as the numerous and sometimes very old examples of retaining walls show.

Es ist auch bekannt (AT-B-217 676), an der Mauerrückseite von zu sanierenden Stützmauern senkrechte, im Abstand zueinander stehende Trennwände zu errichten, um den Erddruck zu verringern. Diese Trennwände werden bei dem bekannten Verfahren dadurch gebildet, daß nacheinander in vielen benachbarten Bereichen des Erdreichs Injektionen vorgenommen werden. Damit diese von den Injektionen erfassten Bereiche zur Bildung einer Trennwand einen Zusammenhang bekommen, werden Anker von der Stützmauer her in diese Bereiche vorgetrieben.It is also known (AT-B-217 676) to erect vertical, spaced-apart partition walls on the rear side of retaining walls to be renovated in order to reduce the earth pressure. In the known method, these dividing walls are formed in that injections are carried out successively in many neighboring regions of the earth. Anchors are driven from the retaining wall into these areas so that these areas covered by the injections are related to the formation of a partition.

Obwohl es fraglich erscheint, ob mit derartigen Injektionen in das Erdreich wirksame Trennwände aufgebaut werden können, ist zumindest festzustellen, daß die Wirkung dieser Trennwände nicht darin besteht, die Stützmauer abzufangen, sondern im wesentlichen nur darin, in dem dahinter anstehenden Erdreich durch Unterteilung eine Silowirkung zu erreichen, wodurch der Erddruck soweit gemindert wird, daß die Stützmauer dem Erddruck wieder standhalten kann, insbesondere nachdem sie in üblicher Weise von der Vorderseite durch Verfugen und Ausspritzen saniert wurde.Although it appears questionable whether effective partition walls can be built with such injections into the ground, it can at least be stated that the effect of these partition walls is not to intercept the retaining wall, but essentially only to create a silo effect in the soil behind it by subdivision to reach, causing the earth pressure so far is reduced that the retaining wall can withstand the earth pressure again, especially after it has been renovated in the usual way from the front by grouting and spraying.

Aufgabe der Erfindung ist es daher, ein statisch nachweisbares Verfahren der eingangs genannten Gattung zu schaffen, mit dem zu sanierende Stützmauern abgefangen werden können, wobei die an der Mauerrückseite vorzunehmenden Maßnahmen mit möglichst geringem Aufwand verbunden sein sollen und wobei die Mauervorderseite unbeeinträchtigt bleiben soll.The object of the invention is therefore to provide a statically verifiable method of the type mentioned, with which retaining walls to be renovated can be intercepted, the measures to be carried out on the back of the wall being connected with as little effort as possible and the front of the wall should remain unaffected.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Verstärkungsrippen als Pfeiler-Rücklagen durch Verzahnung mit der dem Erdreich zugekehrten unregelmäßigen Mauerrückseite zu einer monolithischen Einheit Verbunden werden und daß an der Mauerrückseite den vorgesehenen Pfeilerquerschnitten entsprechende Hohlräume hergestellt und anschließend mit zementgebundenem Pfeilermaterial verfüllt werden.This object is achieved in that the reinforcing ribs as pillar reserves are connected by a toothing with the irregular wall back facing the ground to form a monolithic unit and that corresponding cavities are made on the back of the wall and then filled with cement-bound pillar material.

Die so gebildeten Pfeiler-Rücklagen, die im Abstand zueinander ausgeführt werden und eine im Verhältnis zur Gesamtfläche der Stützmauer nur verhältnismäßig kleine Querschnittsfläche einnehmen, bilden mit der Stützmauer durch Verzahnung mit der unregelmäßigen Mauerrückseite eine innige Verbindung und eine monolithische Einheit. An der Verbindungsstelle zur Stützmauer üben die Pfeiler-Rücklagen eine Stützwirkung auf die Stützmauer aus, die vergleichbar mit der Stützwirkung eines an der Mauervorderseite angeordneten Stützpfeilers ist. Das Prinzip beruht auf der Rippenverstärkung freier Mauerlängen sowie der Abminderung des Erddruckes durch Aufnahme von Reibungskräften an den durch Flächenvermehrung zusätzlich geschaffenen Rippenflächen (Pfeilerflächen).The pillar reserves formed in this way, which are spaced apart and occupy a relatively small cross-sectional area in relation to the total area of the retaining wall, form an intimate connection and a monolithic unit with the retaining wall by interlocking with the irregular back of the wall. At the connection point to the retaining wall, the pillar reserves exert a supporting effect on the retaining wall that is comparable to the supporting effect of a supporting pillar arranged on the front side of the wall. The principle is based on reinforcing the ribs of free wall lengths and reducing the earth pressure by absorbing frictional forces on the rib surfaces (pillar surfaces) created by increasing the area.

Die Aufnahme des Erddruckes kann so mit Hilfe von Bodenkennwerten nachgewiesen werden und stellt ein statisch bestimmbares System dar, das auf die in der AT-PS 217 676 vorgesehene Konstruktiv-Lösung verzichten kann.The recording of the earth pressure can be verified with the help of soil parameters and represents a statically determinable system that can do without the constructive solution provided in AT-PS 217 676.

Im Gegensatz zur Schwergewichtsmauer wird das statische System durch eine "Einfeld-Balkenwirkung" von Pfeiler und Pfeiler erreicht und die Abstände der Pfeiler so klein gehalten, daß der verbleibende Zwischenraum keine Zugbeanspruchung des Mauerwerks zuläßt. Die Abmessungen der Pfeiler-Rücklagen sind dabei verhältnismäßig klein und beschränken sich auf das statische Mindestmaß.In contrast to the heavyweight wall, the static system is achieved by a "single-field beam effect" of pillars and pillars and the spacing of the pillars is kept so small that the remaining space does not allow tensile stress on the masonry. The dimensions of the pillar reserves are relatively small and are limited to the minimum static size.

Die Hohlräume werden dabei durch Einblasen von Kies-Körnung verfüllt und durch Einpressen von Zementsuspension vermörtelt. Die Verstärkungsrippen bestehen somit aus Beton, der auch ohne Bewehrungen eine ausreichende Zugfestigkeit, insbesondere an der Verbindungsstelle zur Mauerrückseite aufweist, um die erforderlichen Stützkräfte auf die Stützmauer zu übertragen.The cavities are filled in by blowing in gravel and mortar is injected by injecting cement suspension. The reinforcing ribs are thus made of concrete, which has sufficient tensile strength even without reinforcement, in particular at the connection point to the rear of the wall, in order to transmit the required supporting forces to the retaining wall.

Gemäß einer bevorzugten Ausgestaltung des Verfahrens ist vorgesehen, daß die Hohlräume jeweils durch eine oder mehrere durch die Stützmauer reichende Spülbohrungen und Ablaufbohrungen ausgespült und die Mauerrückseite mittels Hochdruck-Wasserstrahlen gereinigt wird, bevor das Pfeilermaterial in die Hohlräume eingebracht wird. Auf diese Weise lassen sich mit sehr geringen, das Aussehen der Stützmauer nicht verändernden Eingriffen an der Stützmauer die erfoderlichen Arbeiten an der Mauerrückseite ausführen.According to a preferred embodiment of the method it is provided that the cavities are rinsed out by one or more flushing bores and drain bores reaching through the retaining wall and the back of the wall is cleaned by means of high-pressure water jets before the pillar material is introduced into the cavities. In this way, the required work on the back of the wall can be carried out with very minor interventions on the retaining wall that do not change the appearance of the retaining wall.

Weitere vorteilhafte Ausgestaltungen des Erfindungsgedankens sind Gegenstand weiterer Unteransprüche.Further advantageous embodiments of the inventive concept are the subject of further dependent claims.

Die Erfindung wird nachfolgend an einem Ausführungsbeispiel näher erläutert, das in der Zeichnung darstellt ist. Es zeigt:

  • Fig. 1 eine Stützmauer mit dahinter angeordneter Pfeiler-Rücklage im Schnitt,
  • Fig. 2 die Stützmauer nach Fig. 1 im Grundriß und
  • Fig. 3-6 die einzelnen Verfahrensschritte zur Herstellung der in den Fig. 1 und 2 gezeigten Pfeiler-Rücklagen an der Stützmauer.
The invention is explained in more detail below using an exemplary embodiment which is illustrated in the drawing. It shows:
  • 1 is a retaining wall with a pillar reserve arranged behind it in section,
  • Fig. 2, the retaining wall of FIG. 1 in plan and
  • Fig. 3-6 the individual process steps for producing the pillar reserves shown in Figs. 1 and 2 on the retaining wall.

Eine beispielsweise aus altem Mauerwerk bestehende Stützmauer 1, die nach ihrem Querschnitt statisch nicht als Schwergewichtsmauer anzusehen ist, stützt das dahinter anstehende Erdreich 2. Wenn erforderlich, kann die Stützmauer 1 in üblicher Weise von der Vorderseite 3 her saniert worden sein, insbesondere durch Auspressen des Mauerwerks mit Mörtel und durch Verfugen.A retaining wall 1 consisting, for example, of old masonry, which according to its cross-section cannot be regarded statically as a heavyweight wall, supports the soil behind it. If necessary, the retaining wall 1 can be renovated in the usual way from the front side 3, in particular by pressing out the Masonry with mortar and by grouting.

Um zu erreichen, daß die Stützmauer dem Erddruck des dahinter anstehenden Erdreichs 2 standhält, sind an der Rückseite der Stützmauer 1 in statisch bestimmbaren Abständen Pfeiler-Rücklagen 4 angebracht worden, die Verstärkungsrippen bilden. Wie man aus Fig. 1 erkennt, können die Pfeiler-Rücklagen beispielsweise trapezförmig sein. Von einer Pfeilerkrone 5 nimmt die Pfeilertiefe bei gleichbleibender Breite bis zum Pfeilerfuß 6 hin zu. Stattdessen können auch andere Pfeilerformen gewählt werden, beispielsweise Dreieckform. Vorzugsweise liegt die Pfeilerkrone 5 unterhalb der Erdoberfläche. Es ist aber auch möglich, die Pfeiler-Rücklage 4 bis zur Oberfläche des hinter der Stützmauer 1 anstehenden Erdreichs 2 hochzuführen. In diesem Fall ist es besonders einfach, den zur Bildung der Pfeiler-Rücklagen 4 erforderlichen Hohlraum an der Mauerrückseite herzustellen und mit dem Pfeilermaterial zu verfüllen.In order to ensure that the retaining wall withstands the earth pressure of the soil 2 behind it, pillar reserves 4, which form reinforcing ribs, have been attached to the rear of the retaining wall 1 at statically determinable intervals. As can be seen from Fig. 1, the pillar reserves can be trapezoidal, for example. The pillar depth increases from a pillar crown 5 to the pillar foot 6 with a constant width. Instead, other pillar shapes can also be selected, for example triangular shapes. The pillar crown 5 is preferably below the surface of the earth. However, it is also possible to raise the pillar reserve 4 up to the surface of the soil 2 behind the retaining wall 1. In this case, it is particularly easy To create the pillar reserves 4 necessary cavity on the back of the wall and fill with the pillar material.

Bei dem dargestellten Ausführungsbeispiel, bei dem die Pfeilerkrone 5 unterhalb der Erdoberfläche liegt, wird der dem Pfeilerquerschnitt entsprechende Hohlraum 7 (Fig. 3) an der Mauerrückseite 8 dadurch hergestellt, daß von der Mauervorderseite 3 eine oder mehrere Spülbohrungen 9 ausgeführt werden, durch die Spüldüsen 10 eingeführt werden. Am Fuß der Stützmauer 1 werden eine oder mehrere Ablaufbohrungen 10 vorgesehen.In the illustrated embodiment, in which the pillar crown 5 lies below the surface of the earth, the cavity 7 corresponding to the pillar cross-section (FIG. 3) is produced on the rear wall 8 in that one or more flushing holes 9 are made from the front wall 3 through the flushing nozzles 10 will be introduced. At the foot of the retaining wall 1, one or more drain holes 10 are provided.

Mit den Spüldüsen 10 wird das Erdreich an der Mauerrückseite 8 in dem statisch bestimmten Bereich ausgespült und durch die Ablaufbohrungen 10a heraustransportiert, bis der Hohlraum 7 in der gewünschten Form entstanden ist. Durch Wasserstrahlen 11 (Fig. 4), die von einer Spüldüse 12 gegen die Mauerrückseite 8 gerichtet werden, wird die Mauerrückseite 8 vollständig gereinigt. Dann wird das Pfeilermaterial in den Hohlraum 7 eingebracht. Hierzu kann beispielsweise durch eine größere Öffnung 13 zunächst eine Kiesfüllung 14 in den Hohlraum eingeblasen werden, die dann durch das Einpressen von Zementsuspension mittels einer Injektionslanze 15 vermörtelt wird.With the flushing nozzles 10, the soil on the back of the wall 8 is flushed out in the statically determined area and transported out through the drain holes 10a until the cavity 7 is formed in the desired shape. The back of the wall 8 is completely cleaned by water jets 11 (FIG. 4) which are directed against the back of the wall 8 by a rinsing nozzle 12. The pillar material is then introduced into the cavity 7. For this purpose, for example, a gravel filling 14 can first be blown into the cavity through a larger opening 13, which is then mortared by the injection of cement suspension by means of an injection lance 15.

Die nach dem Abbinden aus Beton bestehenden Pfeiler-Rücklagen 4 bilden zusammen mit der Stützmauer 1 ein monolithisch einheitliches Gebilde, das ausreichend steif ist, um den Erddruck des anstehenden Erdreichs aufzunehmen.The pillar reserves 4 made of concrete after setting together with the retaining wall 1 form a monolithically uniform structure which is sufficiently stiff to absorb the earth pressure of the existing soil.
