Definitions
- the invention relates to a method for securing Terrain jumps, with a distance in front of the cut A retaining wall is erected on the floor and the space between the Retaining wall and the cut floor is filled.
- Lighter support structures based on the principle of the reinforced Earth require a wider excavation space and accordingly a larger backfill volume.
- the also easy Floor nailing is required when the vertical front wall is required often difficult to manufacture with the soil in front, and that too demanding security against frost and water damage is only to achieve with greater effort.
- the object of the invention is a method of the beginning to create the type mentioned, with which in simple, a cost-effective and environmentally friendly way of securing Terrain jumps is made possible.
- This object is achieved in that pairs from precast slabs to foundation pillars and through In-situ concrete or mortar grouting are connected to the room between them and the grown soil with bulk material or Soil is backfilled and drained, and that earth anchor through the plates inserted in the grown soil and against the Plates are strained.
- the foundation piers are preferably below the vertical ones Butt joints of the precast panels and extend into frost-free Lows.
- the foundations are preferred as prefabricated parts in the Soil driven in or inserted into boreholes or from In-situ concrete made in boreholes.
- the upcoming soil is exploiting the capillary cohesion as steep as possible and as close as possible to the wall dug out.
- the precast panels are used until the Provisionally counter ground anchor using the anchor heads Tipped over secured.
- the space between the precast panels and the cut one Soil is filled with soil or bulk material that is compressed and receives drainage.
- the filling is preferably made of bulk material or earth material installed in layers and compacted in such a way that the tension rods the ground anchor is embedded on the surface of such a layer are.
- the ground anchors made of tension rods extend into boreholes grown soil and are with this by mortar or Granules bonded in a shear-resistant manner.
- the tie rods can Have anchor heads in wall recesses and light be tense.
- the wall produced by the method according to the invention consists of prefabricated pairs of plates 1 basically any, sufficiently strong and stable building materials, e.g. Concrete, wood or steel. It rests on the vertical Impacts on foundation pillars 2. These lead up to frost-free floor and have one to accommodate the Wall weight sufficient diameter.
- the gap between the inner and outer slab is made with concrete or pour mortar.
- the earth pressure on the wall is caused by Ground anchor 3 transferred into the grown soil 4. This is the foundation effort with sufficient frost protection less than with floating support structures, and the The effort for anchoring is less than for the Reinforced earth and soil nailing.
- the thing to be moved Soil volume is less than the above Construction methods apart from soil nailing.
- the pillars are like axially stressed piles for load transfer dimensioned, but require because of the small Wall weight and usually in frost-free depth considerable soil strength only small dimensions.
- Manufacturing costs are low: as prefabricated parts made of concrete or steel, they are driven in dynamically, from in-situ concrete they can be temporary due to capillary cohesion stable boreholes can be used easily. Also Combination designs are possible, e.g. with a gradually widened by displacing and repeated borehole filled with dry mortar using a pneumatic hammer.
- To put on the walls get the Pillar headboards 5 made of concrete or metal. The walls will temporarily supported with supports 6. The joints between the walls are used - if necessary using a Hose 7 in grooves - shear-proof closed.
- the plates have anchor heads with holes 8 for passage the anchor rods.
- the upcoming floor is under Utilization of the capillary cohesion as steep and in cut short distance from the foundation pillars 4.
- Through the Wall openings 8 through holes for the anchor in the grown soil using a displacement hammer or a Snail drilled.
- Tension rods 10 are in the boreholes used, and the annular gap 11 is used for thrust transmission using mortar or compacted granulate (principle of Sand anchor) filled.
- the anchor heads are in wall holes already installed, and the anchors were against the thrust transmission line slightly tense in the grown soil.
