Abstract

Bei einem Verfahren zur Sanierung und/oder Strukturverbesserung des Bodenbereiches unterhalb des Oberbaus eines Bahngleises, einer Fahrbahn oder innerhalb eines Wasserschutzdammes mit einer schalungsfrei nach dem Prinzip der Messerschildtechnik arbeitenden, selbsttätig fortschreitenden Grabenaushubeinrichtung (1), bei der an dem vorderen Ende Bodenmaterial ausgehoben und an dem hinteren Ende aufbereitetes Bodenmaterial wiederaufgefüllt oder gleichzeitig verdichtet wird, soll die Dauerstrukturfestigkeit des aufbereiteten bzw. sanierten Bodenmaterials verbessert werden.In a process for renovation and / or structural improvement the floor area below the superstructure of a train track, a roadway or within a water dam with formwork-free according to the principle of knife shield technology working, progressive trench excavation (1), at the front end of floor material excavated and processed at the rear end Soil refilled or compacted at the same time is the permanent structural strength of the processed or renovated soil material can be improved.

Zu diesem Zweck wird zumindest an einer der Seitenwände und/oder an dem Boden des ausgehobenen Grabens vor dem Wiederauffüllen jeweils eine einseitig undurchlässige Drainagematte (11) als Bahnenmaterial von der Grabenaushubeinrichtung (1) aus kontinuierlich mit dem Fortschreiten dieser Einrichtung aufgebracht.

Figure 00000001
For this purpose, at least on one of the side walls and / or on the bottom of the excavated trench, a drainage mat (11), which is impermeable on one side, is continuously applied as sheet material from the trench excavation device (1) as the device progresses.
