Definitions
- 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.
- 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.
- 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.
- 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.
- 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.
- the sheet pile 10 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.
- 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.
- 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.
- 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 shows the state in which the sheet pile 10 into Layer 18 was driven and a bit into the Layer 18 protrudes.
- 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.
- Suspension is pressed into the free soil.
- Suspension is, for example, concrete. It fills the slot 19 completely.
- 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.
- 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.
