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 Then the spigot board is withdrawn, so that a slot (19) is formed in the earth area, in which a sealing concrete suspension is injected through a tube (12).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 of soil, especially of pit walls, under Piling sheet piles 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.The support and sealing of construction pit walls often leads to big trouble, especially if it is very deep Construction pits act and there is oppressive groundwater. A sheeting wall made from a single-phase suspension is Although suitable for sealing, it cannot be a larger one Take over earth pressure forces. Sheet piling, Peinerprofil walls or Drilling walls meet both requirements per se, but has emphasized that in the case of deep excavation pits, problems with the lower ends can occur, especially if the walls by vibrating or ramming. Will one Steel wall vibrates or rams into the ground, especially if, for example, B. with water is rinsed along the screed in a rinsing channel Floors z. B. Tone an oversized slot, d. H. a slit that is not filled in by the sheet pile, and in non-cohesive Soils a disturbed zone in the ground along the sheet pile. This area can be used along the smooth sheet pile Groundwater around the end of the sheet pile and into the Flowing in the construction pit. The rush of water gets bigger the more Immerse the pit walls deeper into 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 has for its object a method for Supporting and sealing soil to indicate that also under difficult circumstances can be successfully carried out and in which Troubles can be prevented.

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,
  • Zurückziehen des Wandelements (10) unter Belassung eines Schlitzes (19) und Einbringen einer dichtenden Suspension durch das mindestens eine Rohr zum Auffüllen des Schlitzes.
  • Wiederabsenken des Wandelements in den gefüllten Schlitz,
  • Erzeugung einer dichtenden Ummantelung um das untere Ende des Wandelements und dessen Verbindung mit der Bodenschicht.
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,
  • Retracting the wall element (10) leaving a slot (19) and introducing a sealing suspension through the at least one tube to fill the slot.
  • 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 bottom layer.

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, the sheet pile is removed Reaching the bottom layer with low water permeability so to speak, a shoe cast from suspension, which deals with sealing the sheet pile and the surrounding soil combines. In this way, sliding gaps for the Groundwater avoided along the sheet pile. The shoe works a tight bond between the sheet pile and the surrounding soil. Thus it is possible to support and with simple means to seal soil at the same time. This is the Production of very deep construction pits with considerable Groundwater pressure possible.

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 inventive method requires the use of Wall elements such as sheet piles or steel elements that pass through Locks connected with each other and with at least each are provided with a longitudinal pipe. Such wall elements are known. The tubes form rinsing tubes through which to Supporting the advance while shaking water is supplied. The tubes 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 used using the Pipes are carried out as rinsing pipes, the pipes then be used for the suspension. In this case double use of the pipes is possible. With the pipes it can be metal pipes or plastic pipes, which are connected to the wall element.

Im folgenden wird unter Bezugnahme auf die Zeichnungen ein Ausführungsbeispiel der Erfindung näher erläutert. The following is a reference to the drawings Embodiment of the invention explained in more detail.

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.1 is a wall element in the form of a sheet pile 10 shown, which generally has an 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 are also suitable. The sheet pile 10 consists of a rolled sheet 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 in an inside corner of the sheet pile profile runs and in extends essentially over the entire length of the sheet pile. Another tube 12 is in the opposite inner corner intended. Each of the tubes 12 can be on its rear (Upper) end to be connected to a flushing line 13 the water is supplied, which at the lower end of the pipe, d. H. at the bottom of the sheet pile, emerges.

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.1, the sheet pile becomes vertical in the floor 15 introduced standing, with at the rear upper end Sheet pile 10 attacks a vibrating device 14 according to FIG. 2, which is provided with two gripping tongs 14a, which on the attack straight sections of the sheet pile profile and the Vibration movements of the vibrator 14 on the Sheet pile 10 transferred.

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 embodiment, it is assumed that the upper floor layer 16 consists of gravel. Gravel is in a lot highly water permeable. Below is one Layer 17 of sand of moderate water permeability, and beneath this is a layer 18 of less clay Water permeability. With the sheet pile wall made up of numerous interlocking sheet piles 10 is intended to be an excavation pit be excavated and sealed off. To do this, the sheet piles 10 to the layer 18 low water permeability or at least up to layer 17 of sand with moderate Water permeability can be advanced.

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.Fig. 2 shows the state in which the sheet pile 10 into Layer 18 was driven and a bit into the Layer 18 protrudes. By shaking the sheet pile 10 the clay layer does not seal the sheet pile on. Rather, remains between the sheet pile and the Clay layer is a gap through which the sheet piles flow can. The sheet pile ends in the sand with moderate Water permeability, can run through the disturbed floor the sheet pile is flowing around 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 a bit wide withdrawn so that in the layer 18 or 17 a Slit 19 forms from the profile of the sheet pile. During the Withdrawal is a sealing through the tubes 11, 12 Suspension is pressed into the free soil. At this Suspension is, for example, concrete. It fills the slot 19 completely. In the with the liquid Suspension filled slot 19 is then the Sheet pile 10 again with the addition of suspension depressed. The suspension spreads along the sheet pile and penetrates into the ground if possible. During the setting, it connects firmly with both Floor as well as with the sheet pile. This creates one Sheathing 20 that surrounds the lower end of the sheet pile and blocked any flow path. Now the construction pit 21 can be excavated without groundwater having a larger Flow rate flows into it.

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 during the bringing down of the sheet pile a flushing with water takes place through the pipes 11 and 12 Support and accelerate the tunneling process. The same tubes are then used in FIG. 3 shown condition, the suspension is injected into the ground.
