Abstract

The method is for supporting and sealing an earth area involves a spigot board (10) and a sieve device (14) installed in the ground until the lower end has penetrated a ground layer (18) with reduced water permeability. Then the spigot board is withdrawn, so that a slot (19) is formed in the earth area, in which a sealing concrete suspension is injected through a tube (12). Finally, the spigot board is pressed back into the filled slot. On hardening, the concrete suspension forms a concrete surround at the lower end of the spigot board, which is connected in a sealed manner both with the surrounding earth and the spigot board.

Description

Die Erfindung betrifft ein Verfahren zum Stützen und Abdichten von Erdreich, insbesondere von Baugrubenwänden, unter Einbringung von mit Rohren versehenen Spundbohlen in den Boden.The invention relates to a method for supporting and sealing soil, in particular construction pit walls, by introducing sheet piles provided with pipes into the ground.

Das Stützen und Abdichten von Baugrubenwänden führt oftmals zu großen Schwierigkeiten, insbesondere wenn es sich um sehr tiefe Baugruben handelt und drückendes Grundwasser vorhanden ist. Eine aus einer Einphasensuspension hergestellte Verbauwand ist zwar zum Abdichten geeignet, kann jedoch keine größeren Erddruckkräfte übernehmen. Spundwände, Peinerprofilwände oder Bohrwände erfüllen an sich beide Anforderungen, jedoch hat sich herausgestellt, dass bei tiefen Baugruben Umläufigkeiten an den unteren Enden auftreten können, insbesondere wenn die Wände durch Vibrieren oder Rammen eingebracht wurden. Wird eine Stahlwand in das Erdreich vibriert oder gerammt, so entsteht, insbesondere dann, wenn als Einbringhilfe z. B. mit Wasser gespült wird, entlang der Bohle ein Spülkanal, in bindigen Böden z. B. Ton ein Schlitz mit Übermaß, d. h. ein Schlitz, der von der Spundbohle nicht ausgefüllt wird, und in nichtbindigen Böden eine gestörte Zone im Erdreich entlang der Spundbohle. Durch diesen Bereich kann entlang der glatten Spundbohle Grundwasser um das Ende der Spundbohle herumlaufen und in die Baugrube einströmen. Der Wasserandrang wird um so größer, je tiefer die Baugrubenwände in das Grundwasser eintauchen.Supporting and sealing the walls of construction pits often leads to great difficulties, especially when the excavation pits are very deep and the groundwater is pressing. A sheeting wall made from a single-phase suspension is suitable for sealing, but cannot take on larger earth pressure forces. Sheet piling, Peinerprofil walls or drilling walls meet both requirements per se, but it has been found that in deep construction pits, circumferences can occur at the lower ends, especially if the walls were brought in by vibration or ramming. Will one Steel wall vibrates or rammed into the ground, so arises, especially if, for example, as an insertion aid. B. is rinsed with water, along the screed a rinsing channel, in cohesive soils z. B. clay a slot with oversize, ie a slot that is not filled by the sheet pile, and in non-cohesive soils a disturbed zone in the ground along the sheet pile. Through this area, groundwater can run along the smooth sheet pile around the end of the sheet pile and flow into the construction pit. The rush of water increases, the deeper the walls of the construction pit are immersed in the groundwater.

Der Erfindung liegt die Aufgabe zugrunde, ein Verfahren zum Stützen und Abdichten von Erdreich anzugeben, das auch unter schwierigen Umständen mit Erfolg durchführbar ist und bei dem Umläufigkeiten verhindert werden.The invention is based on the object of specifying a method for supporting and sealing soil which can be carried out successfully even under difficult circumstances and which prevents circumferences.

Die Lösung dieser Aufgabe erfolgt erfindungsgemäß mit den im Patentanspruch 1 angegebenen Merkmalen. Hiernach sieht das erfindungsgemäße Verfahren die folgenden Schritte vor:

  • Niederbringen der Wandelemente durch Rütteln, Vibrieren oder Rammen bis zum Erreichen einer Bodenschicht mit geringer Wasserdurchlässigkeit,
  • Vortreiben des Wandelements in diese Bodenschicht,
  • Wiederabsenken des Wandelements in den gefüllten Schlitz,
  • Erzeugung einer dichtenden Ummantelung um das untere Ende des Wandelements und dessen Verbindung mit der Bodenschicht und der Spundbohle.
This object is achieved according to the invention with the features specified in claim 1. The method according to the invention then provides for the following steps:
  • Bringing down the wall elements by shaking, vibrating or ramming until a floor layer with low water permeability is reached,
  • Advancing the wall element into this floor layer,
  • Lowering the wall element again into the filled slot,
  • Creation of a sealing jacket around the lower end of the wall element and its connection to the floor layer and the sheet pile.

Bei dem erfindungsgemäßen Verfahren wird der Spundbohle nach Erreichen der Bodenschicht geringer Wasserdurchlässigkeit gewissermaßen ein Schuh aus Suspension angegossen, der sich mit der Spundbohle und dem umgebenden Erdreich abdichtend verbindet. Auf diese Weise werden Gleitspalten für das Grundwasser entlang der Spundbohle vermieden. Der Schuh bewirkt einen dichten Verbund zwischen Spundbohle und umgebendem Boden. Somit gelingt es, mit einfachen Mitteln eine Stützung und zugleich Abdichtung von Erdreich vorzunehmen. Dadurch ist die Herstellung sehr tiefer Baugruben mit erheblichem Grundwasserdruck möglich.In the method according to the invention, after reaching the bottom layer with low water permeability, a shoe made of suspension is cast, which connects to the sheet pile and the surrounding soil in a sealing manner. In this way, crevices for the groundwater along the sheet pile are avoided. The shoe creates a tight bond between the sheet pile and the surrounding soil. So it is possible to support and seal soil with simple means. This enables the construction of very deep construction pits with considerable groundwater pressure.

Das erfindungsgemäße Verfahren erfordert die Benutzung von Wandelementen, wie Spundbohlen oder Stahlelementen, die durch Schlösser miteinander verbunden und mit jeweils mindestens einem längslaufenden Rohr versehen sind. Solche Wandelemente sind bekannt. Die Rohre bilden dabei Spülrohre, durch die zur Unterstützung des Vortriebs beim Rütteln Wasser zugeführt wird. Hierbei haben die Rohre eine reine Spülfunktion.The method according to the invention requires the use of wall elements, such as sheet piles or steel elements, which are connected to one another by locks and each provided with at least one longitudinal pipe. Such wall elements are known. The tubes form rinsing tubes through which water is supplied to support the propulsion when shaking. The pipes have a purge function.

Das erfindungsgemäße Verfahren kann auch unter Benutzung der Rohre als Spülrohre durchgeführt werden, wobei die Rohre anschließend für die Suspension benutzt werden. In diesem Falle ist eine Doppelausnutzung der Rohre möglich. Bei den Rohren kann es sich um Metallrohre oder auch Kunststoffrohre handeln, die mit dem Wandelement verbunden sind.The method according to the invention can also be carried out using the tubes as rinsing tubes, the tubes then being used for the suspension. In this case, double use of the pipes is possible. The pipes can be metal pipes or plastic pipes that are connected to the wall element.

Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert.In the following an embodiment of the invention will be explained with reference to the drawings.

In Fig. 1 ist ein Wandelement in Form einer Spundbohle 10 dargestellt, die generell S-förmiges Profil hat. Diese Spundbohle ist nur als Beispiel zu verstehen. Es gibt eine große Vielzahl anderer Spundbohlen- oder Stahlprofile, die sich ebenfalls eignen. Die Spundbohle 10 besteht aus einem gewalzten Stahlprofil und kann eine Länge bis zu 50 m haben.In Fig. 1, a wall element in the form of a sheet pile 10 is shown, which has a generally S-shaped profile. This sheet pile is only to be understood as an example. There is a large variety of other sheet piling or steel profiles that are also suitable. The sheet pile 10 consists of a rolled steel profile and can have a length of up to 50 m.

Die Spundbohle 10 weist ein längslaufendes Rohr 11 auf, das in einer Innenecke des Spundbohlenprofils verläuft und sich im wesentlichen über die gesamte Länge der Spundbohle erstreckt. Ein weiteres Rohr 12 ist in der gegenüberliegenden Innenecke vorgesehen. Jedes der Rohre 12 kann an seinem rückwärtigen (oberen) Ende mit einer Spülleitung 13 verbunden werden, durch die Wasser zugeführt wird, welches am unteren Rohrende, d. h. am unteren Ende der Spundbohle, austritt.The sheet pile 10 has a longitudinal tube 11 which runs in an inner corner of the sheet pile profile and extends essentially over the entire length of the sheet pile. Another tube 12 is provided in the opposite inner corner. Each of the tubes 12 can be connected at its rear (upper) end to a flushing line 13, through which water is supplied, which emerges at the lower end of the tube, ie at the lower end of the sheet pile.

Gemäß Fig. 1 wird die Spundbohle in den Boden 15 senkrecht stehend eingebracht, wobei am rückwärtigen oberen Ende der Spundbohle 10 eine Rüttelvorrichtung 14 gemäß Fig. 2 angreift, welche mit zwei Greifzangen 14a versehen ist, die an den geraden Abschnitten des Spundbohlenprofils angreifen und die Vibrationsbewegungen der Rüttelvorrichtung 14 auf die Spundbohle 10 übertragen.According to FIG. 1, the sheet pile is inserted vertically into the floor 15, a vibrating device 14 according to FIG. 2 engaging at the rear upper end of the sheet pile 10, which is provided with two gripping tongs 14 a which engage the straight sections of the sheet pile profile and which Vibration movements of the vibrating device 14 are transmitted to the sheet pile 10.

Bei dem vorliegenden Ausführungsbeispiel wird angenommen, dass die obere Bodenschicht 16 aus Kies besteht. Kies ist in sehr hohem Maße wasserdurchlässig. Darunter befindet sich eine Schicht 17 aus Sand von mäßiger Wasserdurchlässigkeit, und unter dieser befindet sich eine Schicht 18 aus Ton von geringer Wasserdurchlässigkeit. Mit der Spundwand, die aus zahlreichen ineinandergreifenden Spundbohlen 10 besteht, soll eine Baugrube ausgehoben und abgeschottet werden. Dazu müssen die Spundbohlen 10 bis in die Schicht 18 geringer Wasserdurchlässigkeit oder mindestens bis zur Schicht 17 aus Sand mit mäßiger Wasserdurchlässigkeit vorgetrieben werden.In the present exemplary embodiment, it is assumed that the upper bottom layer 16 consists of gravel. Gravel is very permeable to water. Below this is a layer 17 of sand with moderate water permeability, and below this is a layer 18 of clay with low water permeability. With the sheet pile wall, which consists of numerous interlocking sheet piles 10, an excavation pit is to be excavated and sealed off. For this purpose, the sheet piles 10 must be driven into layer 18 with low water permeability or at least up to layer 17 of sand with moderate water permeability.

Fig. 2 zeigt den Zustand, in dem die Spundbohle 10 bis in die Schicht 18 hinein vorgetrieben wurde und ein Stück weit in die Schicht 18 hineinragt. Durch das Rütteln der Spundbohle 10 schließt sich die Tonschicht nicht abdichtend an die Spundbohle an. Vielmehr verbleibt zwischen der Spundbohle und der Tonschicht ein Spalt, durch den die Spundbohle umströmt werden kann. Endet die Spundwand im Sand mit mäßiger Wasserdurchlässigkeit, kann durch den gestörten Boden entlang der Spundwand die Spundbohle umströmt werden.2 shows the state in which the sheet pile 10 has been driven into the layer 18 and protrudes a little into the layer 18. By shaking the sheet pile 10, the clay layer does not seal the sheet pile. Rather, a gap remains between the sheet pile and the clay layer, through which the sheet pile can flow. If the sheet pile ends in the sand with moderate water permeability, the sheet pile can flow around through the disturbed soil along the sheet pile.

Gemäß Fig. 3 wird die Spundbohle 10 ein Stück weit zurückgezogen, so dass sich in der Schicht 18 oder 17 ein Schlitz 19 von dem Profil der Spundbohle bildet. Während des Zurückziehens wird durch die Rohre 11, 12 eine dichtende Suspension in den frei werdenden Boden gedrückt. Bei dieser Suspension handelt es sich beispielsweise um Betonit. Sie füllt den Schlitz 19 vollständig aus. In den mit der flüssigen Suspension gefüllten Schlitz 19 wird anschließend die Spundbohle 10 unter weiterer Zugabe von Suspension wieder heruntergedrückt. Dabei verteilt sich die Suspension entlang der Spundwand und dringt auch wenn möglich in den Boden ein. Während des Abbindens verbindet sie sich fest sowohl mit dem Boden als auch mit der Spundbohle. Dadurch entsteht eine Ummantelung 20, die das untere Ende der Spundbohle umgibt und jeglichen Umströmungsweg versperrt. Nunmehr kann die Baugrube 21 ausgehoben werden, ohne dass Grundwasser mit größerer Fließrate in sie einströmt.3, the sheet pile 10 is pulled back a little, so that a slit 19 is formed in the layer 18 or 17 from the profile of the sheet pile. During the Withdrawal, a sealing suspension is pressed through the tubes 11, 12 into the released soil. This suspension is, for example, concrete. It completely fills the slot 19. The sheet pile 10 is then pressed back into the slot 19 filled with the liquid suspension with the further addition of suspension. The suspension is distributed along the sheet pile and penetrates into the ground if possible. During setting, it connects firmly to both the floor and the sheet pile. This creates a casing 20 which surrounds the lower end of the sheet pile and blocks any flow path. The excavation pit 21 can now be excavated without groundwater flowing into it at a higher flow rate.

Während des Niederbringens der Spundbohle gemäß Fig. 1 und 2 erfolgt durch die Rohre 11 und 12 eine Spülung mit Wasser, um den Vortriebsvorgang zu unterstützen und zu beschleunigen. Durch die selben Rohre wird anschließend in dem in Fig. 3 dargestellten Zustand die Suspension in den Boden injiziert.1 and 2, the pipes 11 and 12 are flushed with water in order to support and accelerate the driving process. The suspension is then injected into the ground through the same pipes in the state shown in FIG. 3.
