Definitions
- Procedure for securing terrain jumps being at a distance using a retaining wall in front of the cut floor of prefabricated parts and the space between the Retaining wall and the cut floor is filled, whereby the retaining wall by inserted into the grown soil Earth anchor is held.
- 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 precast panels used are massive; your Height is only a fraction of the total erecting retaining wall.
- the ground anchors need to be precise given positions are brought so that they to the Fastening elements on the prefabricated panels to be attached later the retaining wall are aligned.
- 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.
- Retaining wall consists of pairs of precast panels that are on Foundation pillars are set, the precast slabs be connected by in-situ concrete or mortar grouting that the space filled with bulk or earth material between the Precast slabs and the grown soil is drained, and that the ground anchors through the precast slabs in the grown soil used and against the precast panels be tense.
- the foundation pillars are preferably located below the vertical ones Butt joints of the precast panels and extend into frost-free Deep.
- the foundations are preferred as prefabricated parts in the Soil driven in or inserted into boreholes or out In-situ concrete made in boreholes.
- the pairs of precast panels on the Foundation pillars set with connecting parts, together Shear-proof connected by grouting and perforated Anchor heads are provided.
- the existing soil is so using the capillary cohesion as steep as possible and as close as possible to the wall excavated.
- the precast panels are used until the Provisionally counter ground anchors using the anchor heads Tipped over.
- 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 so that the tension rods the ground anchor is embedded on the surface of such a layer are.
- the tie rods of the ground anchors 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 tie rod heads in wall recesses and light be tense.
- the wall produced by the method according to the invention consists of pairs 1 of prefabricated plates basically any, sufficiently firm and stable Building materials, e.g. Concrete, wood or steel. It rests on the vertical joints on foundation pillars 2. These lead to in frost-free soil and have one for receiving the Wall weight sufficient diameter.
- the gap between the inner and outer slab is made of 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 foundation piers 2 are like axially stressed piles Load transfer dimensioned, but require because of the light wall weight and mostly in frost-free depth considerable soil strength only small dimensions.
- the manufacturing effort is 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 easily inserted. Also Combination designs are possible, e.g. with a gradually widened by repetition 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 - if necessary using an inserted Hose 7 in grooves - shear-proof closed.
- the plates have anchor heads 8 with openings for passage the anchor rods.
- the upcoming floor 4 is under Utilization of the capillary cohesion as steep and in cut short distance from the foundation pillars 2.
- a drain pipe 9 the space between the wall and the cut floor 4 first up to the height of the first Anchor layer filled with bulk material or soil.
- Tension rods 10 are inserted into the boreholes and the annular gap 11 is used for thrust transmission using mortar or compacted Granules (principle of the sand anchor) filled.
- the anchor tension rod heads are already built into wall holes, and the ground anchors 3 were grown against the thrust transmission line in the Floor slightly tense.
