Abstract

Building ground is cleared of air raid shelters or concrete building structures. The ground is secured by sheet steel piling, and on one side an excavation with a fall toward the building works is dug out. A tunnel is then made from it to the other side, and the middle part beneath the building is excavated from the opposite long sides of the tunnel and downward, with digger dredgers or earthmovers. The building is caused to sink progressively under its own weight. Preferably the digging from the tunnel is with the same or opposite direction of motion. The movement is effected by steel cables from the opposite sides into the middle of the tunnel, back and forth. The earthmovers are connected by cables to lifters which also fill lorries with the spoil. Less work is required than for explosive shattering of heavy, e.g. military, concrete and its subsequent piecemeal removal.

Die Erfindung betrifft ein Verfahren und eine Vorrichtung zur Preilegung den Bauwerkes oder Wie derbe irutuang dos BaugrvmdoB bezw. zur anderweitige3!! Benutzung des Bauwerkes.The invention relates to a method and a device for prelimitation of the building or How derbe irutuang dos KonstruvmdoB respectively. to the other 3 !! Use of the building.

Bisher mußte das Bauwerk gesprengt,die Sprengteile weitgehend zerkleinert und abtransportiert werden, was sehr erheblichen Zeit und Kostenaufwand erforderte,sodaß regelmäßig daYon abge sehen werden mußte, obwohl oft die *Beseitigung des Bauwerkes für Betonbunker aus Iiriegszeiten häufig dringend erwünscht ii?t.So far the structure had to be blown up, most of the explosive parts be shredded and transported away, which required considerable time and expense, so that daYon are regularly abandoned had to be, although often the * removal of the structure often urgently required for concrete bunkers from times of war.

Erfindungsgomäß wird darin Abhilfe geschaffen das bei den neuen Verfahren(Absenkung) nur ein Bruchteil an Zeit und Eosteil entstehen., außerdem hat das neue Verfahren den Vorteil das die Bunker nach Schaffung neuer Ein u. Ausgänge sowie Isolierung der Aussenflachen für einen späteren Notfall als Atom-Se hu tabau hergerichtet werden kännen,ein weiterer Vorteil liegt darin.daß nun eine neue Bebau -■ ung des Grundstückes erfolgen kann.
Weitere Einzelheiten auf Blatt 2According to the invention, a remedy is created in that with the new method (lowering) only a fraction of time and Eosteil arise. In addition, the new method has the advantage that the bunker after creating new entrances and exits as well as isolation of the outer surfaces for a later emergency as an atom - They can be prepared, another advantage is that new buildings can now be built on the property.

Verfaliren und Vorrichtung zur Beseitigung von Schutzbauten oder Betonbauwe-'k.iM und dergl.Procedures and devices for the removal of protective structures or Betonbauwe-'k.iM and the like.

1. Der Grundwasserspiegel wird auf ca. 15 m Tiefe abgesenkt.1. The groundwater level is lowered to a depth of approx. 15 m.

2. Um den Bunker werden Spundbohlen aus Stahl eingerammt.2. Steel sheet piles are driven in around the bunker.

3. In der Mitte unterhalb des Bunkers wird ein Durchbrach von ca. 2 m breite angelegt.3. In the middle below the bunker there is a breakthrough of about 2 m wide.

4. Der Bodenaushub wird mit einem Bagger,der mit einen Schürf kübel versehen ist ausgeführt.4. The excavation is done with an excavator with a scraper provided is executed.

5. An den Schürfkübel wird ein Stahlseil fest angebracht, daß mit einer Automatischen Seilwinde verbunden ist und hinter dem Bunker steht. Die Seilwinde wird auf Schienen fest mon tiert und ist nach beiden Seiten beweglich.5. A steel cable is firmly attached to the scraper that is connected to an automatic cable winch and behind the bunker. The cable winch is firmly mounted on rails and can be moved to both sides.

6. Der Schürfkübel kann nun mit ililfe der Seilwinde nach hinten unterhalb des Bunkers gezogen werden und dort entsprechend angesetzt worden.6. The scraper can now move backwards with the help of the cable winch be pulled below the bunker and applied accordingly.

7. Zum Schutz der Stahlseile von Bagger u. Seilwinde werden an den Unterkanten des Bunkers Rollen angebracht.7. To protect the steel cables of the excavator and cable winch, rollers are attached to the lower edges of the bunker.

8. Der Bodenaushub erfolgt immer von der Mitte unterhalb des Bunkers wo die Böschungen Trichterförmig zusammen treffen. Der hohe Druck des Bunkers bwirkt das der Boden seitlich nachgibt. Eine evt.-einseitige nachgäbe der Böschung,kann durch eine stärkere wegnähme auf der anderen Seite korigiert werden.8. The soil is always excavated from the center below the Bunkers where the slopes meet in a funnel shape. The high pressure of the bunker affects the bottom laterally gives way. A possible one-sided yield of the embankment can corrected by a stronger removal on the other side will.

S. Bei Bunkern mit Dachaufbauten werden diese vorher abgebaut.S. In the case of bunkers with roof structures, these are dismantled beforehand.

10. Bunker die für eine weitere Verwendung als Atom-Schutzbauten nicht geeignet sind, werden nach der Absenkung mit Sandboden einge schwemmt.10. Bunkers for further use as nuclear protective structures are not suitable, are washed in with sandy soil after subsidence.
