The Steinebach (colloquially: Stuanabach) is a flowing body of water in the Vorarlberg municipality of Dornbirn . It rises at the western foot of the Lank near the border to the community of Schwarzenberg in the parcel "Zweiergrueb"; the source (with kilometers on water kilometers (GwKM) 9.68) lies at an altitude of about 1185  m above sea level. A. and is about 1 km from the Lank-Kreuz and 1.3 km from the Schauner parcel and the Losenpass . About 100 m above the source, a very old connecting path runs through the western Bregenzerwald from Dornbirn via Watzenegg , Schwende and the Bödele to Schwarzenberg , which today only serves as a hiking trail .

The stones stream flows from the source to the west, through pulls the operating area and urban district called after him Steinebach , then leaves in a right curve to the north his mountain valley and joins then at Romberg with the coming of the east from the Eulental, Eulenbach shorter at 457  m above sea level . A. zum Fischbach , which initially continues in the inflow direction of the Steinebach and then flows into the Dornbirner Ach as the Fußenau Canal . The watercourse kilometrage of the confluence is GwKM 5.12, counted upwards from the mouth of the Fußenau Canal, for that of the longer upper reaches of the Steinebach it is counted uphill.

The stone stream is denatured almost along its entire length by artificial banks and an artificial river bed. Its water flow varies greatly between very high after recent rainfall and poor after longer periods of drought.

Surname

In Vorarlberg, the river name Steinebach only occurs in Dornbirn and Bregenz. The field name Steinebach for the Bachtal was first mentioned in 1347.

Economic use

The Steinebach had already been used economically in many ways. In 1595 the water for the first stone mill was bought from the residents of Watzenegg and used ("Rochusse Mühle", "Juniores Mühle"). Part of the water from the Steinebach is still used today to operate a high-pressure turbine in the former factory in Steinebach owned by FM Hämmerle .

Already in the council minutes of the municipality Dornbirn of the 18th century one can read again and again of destruction by the water of the stone brook. The danger from flooding of the stream is still there today. The Steinebach has been installed in several major projects since 2014. Above the former FM Hämmerle company, Steinebach plant, an embankment barrier with a collecting basin for 16,000 m 3 was completed in 2016. The Anwandtobel and the Eisenharzgraben were built in 2015.

In order to offer the smallest possible attack surface during a flood, the artificial bank barriers / bank areas of the Steinebach up to the confluence with the Fischbach have been renovated since 2014.

To relieve the Fischbach flowing below the Steinebach, a 475 m long relief tunnel was planned and explored below the Zanzenberg and has been built since spring 2018, the breakthrough took place on November 13th, 2018, through which overwater can be diverted into the Dornbirner Ache in the final stage . The costs amount to around 6.4 million euros. The exploratory drilling began in February 2016. The tunnel will begin at about 5.90 kilometers of water of the Steinebach and at 15.91 the Dornbirner Ach will flow into it (Achbrücke at the building yard, gradient about 89.4 ‰), the last 200 m be laid in open construction (gradient approx. 4.0 to 11.1 ‰). The jacking is carried out using the microtunneling process, the drill head has a diameter of 2.60 meters and the jacking pipes are re-pressed under constant pressure. Excavated material is rinsed out and processed in a sorting and washing system for further use, whereby the grain size of the excavated stones is between 1 and 10 cm. The advance takes place about 1.5 to a maximum of 2.5 cm / minute (about 4 to 8 meters per day), the drill head executes about 2 to 8 revolutions per minute. Geologically, there is largely loose material with a lot of marl inclusion .

The 134 pipes to be pressed in are 3.5  meters long and 1.90 meters thick with a wall thickness of 30 cm (outer diameter 2.50 meters). Each tube weighs about 18  tons .

The project is expected to be completed in 2019 and will cost 6.4 million euros. In the event of a flood, up to 20 m³ / s should be discharged via a Tyrolean weir and the relief tunnel.
