Definitions
- the invention relates to a method for stabilizing an embankment during a construction project, in which the embankment is gradually dismantled or dismantled.
- the method in question is to be used in particular in the context of construction work in which an embankment is gradually dismantled, the inclination angle of the embankment being to be maintained or to be set variably.
- An example of such a construction project is the pressing of a tunnel structure under a track system.
- the tunnel structure is provided with a cutting construction on the driving side, which is pressed into the sloping face of the ground under the track system.
- the face is dismantled in parallel with the pre-pressing of the tunnel structure, whereby the removal of the bottom of the front edge of the cutting edges should not precede.
- the floor under the track system, and in particular the face must be absolutely stable during the entire construction work if train traffic via the track system is to be maintained.
- the cutting edge construction as short as possible is used. To do this, the face must be steeply bent. In order to implement such an embankment, either suitable soil conditions must be present, or such soil conditions must be created through appropriate soil improvement measures.
- the method according to the invention achieves the above object by the features of claim 1. Thereafter, the method mentioned at the outset is designed in such a way that the ground forming the embankment is pegged in a substantially horizontal direction.
- the stability of the ground of an embankment can not only be increased by vertical dowelling, but that this can also be achieved with horizontal ground dowelling. It has also been recognized 5 that this method is particularly suitable for improving the soil of embankments, since horizontal dowelling can be carried out here from the inclined embankment surface. Horizontal dowelling increases the shear strength of the floor and prevents the formation of sliding surfaces. The spread of vertical loads in the soil is also improved.
- the horizontal floor anchoring proposed according to the invention can be implemented in different forms.
- horizontally oriented wooden piles or metal elements driven horizontally into the slope can be considered.
- holes arranged in a grid starting from the inclined surface of the slope are driven into the ground and then filled with a self-setting compound.
- This measure is not necessarily aimed at improving the soil by means of cavity injection, but primarily at producing piles of the set material that are limited in their dimensions.
- cement or mortar or another material suitable for its strength can be used for this.
- the type of dowelling described above is particularly important with regard to the successive cessive dismantling or dismantling of the embankment is an advantage. The piles created in the ground can simply be broken off piece by piece together with the gradual dismantling of the embankment.
- the holes can be driven into the ground from the surface of the slope.
- the holes are created with the aid of a drilling machine. Since generally good frictional contact is sought between the piles forming the pegging and the surrounding soil, any piping of the borehole should be removed again when filling with a self-setting compound.
- the piles in the building ground created as part of the method according to the invention are primarily subjected to shear or to shearing. Usually, however, there is also a bending load on the piles.
- the bending tensile strength of the piles can advantageously be increased by embedding a reinforcement in the self-setting mass.
- Tension members for example steel tension members or glass fiber tension members, are considered as reinforcement, which are cut off in sections as the slope is gradually dismantled.
- a self-setting mass containing reinforcing fibers can also be used.
- the piles made with it withstand relatively large shear loads and bending loads occurring in the ground, but can still be broken off bit by bit with the gradual dismantling of the slope.
- the length of the piles created by the method according to the invention depends on the one hand on the soil conditions present and on the other hand on the tools used for their manufacture. It is usually on the order of 25 to 50 m.
- the soil forming the slope is then stabilized to a depth of about 20 to 45 m, so that the slope can be dismantled to this depth while maintaining the angle of the slope.
- the ground that then adjoins the slope surface should still be dowelled to a depth of 5 to 10 meters. If the embankment is now to be dismantled further, it is advantageous to dowel the adjoining ground again in such a way that the dowelled ground areas overlap.
- the method according to the invention can advantageously also be used to stabilize a dam - which has an embankment on both sides.
- the soil forming the dam can advantageously be doubled from the two embankment surfaces of the dam. In this context, too, it proves to be advantageous if the pegged floor areas overlap in order to ensure the stability of the floor.
- Fig. 1 shows a schematic cross section through a dam dowelled according to the invention with a track system during a pressing measure
- Fig. 2 is a schematic plan view of the working face of the situation shown in Figure 1.
- the tracks 2 of a track system run on the dam 1 shown in FIG. 1.
- a tunnel structure is pressed through dam 1.
- the tunnel structure consists of several tunnel segments 3, 4, which are then pressed together by the dam 1.
- the tunnel segment 3, which as is first pressed through the dam 1, is provided on the drive side with a cutting construction 5.
- the cutting construction 5 With the cutting construction 5, the upcoming floor of the dam 1 is cut open and then removed from the interior of the tunnel structure.
- the working face, which is gradually dismantled, should always be at the level of the cutting edge.
- the cutting structure 5 in front of the actual tunnel structure is relatively short, on the one hand to keep the top-heavyness of the tunnel structure as small as possible and on the other hand to keep the area between the tunnel structure and the not yet cut open as small as possible.
- the track system located on the dam 1 is neither carried by the tunnel structure nor by the dam 1, but rather only by a track protection system denoted by 6 in FIG. 1 and the construction of the cutting edge cover not shown in FIG. 1.
- the brevity of the cutting construction 5 requires the formation of a relatively steep face, which must be secured to secure the track system above it.
- the stability of the dam 1 is achieved in the exemplary embodiment shown here by substantially horizontal doubling of the soil forming the dam 1.
- horizontal holes are driven into the ground from the face using an anchor drilling machine and filled with grout or a cement suspension.
- the piles 7 are shown here only schematically in the form of their longitudinal axes. The soil is still stabilized even if the piles 7 should break in places during the construction work.
- the improvement of the soil is not primarily based on cavity injections, but rather on the targeted production of piles 7 of grouting mortar or cement stone that are limited in their dimensions.
- the holes are drilled horizontally, each 25 to 50 meters long.
- the length of the piles 7 is selected in the present exemplary embodiment such that a tunnel segment 3 can be pressed into the ground, the piles being broken off piece by piece together with the successive dismantling of the working face. Then - again starting from the then existing face - horizontal piles are created in the ground, which are also only shown schematically in FIG. 1 and are designated by 8. The areas anchored with the piles 7 and 8 overlap in order to ensure the stability of the floor over the entire width of the dam 1.
- the overlapping dowelling of the dam 1 shown in FIG. 1 could also be implemented in the run-up to the actual pressing-through measure by starting from both embankment surfaces of the dam 1 with a floor anchoring.
- the self-setting mass forming the piles 7, 8 is introduced into the boreholes practically without pressing pressure in order to rule out elevations in the track area.
- the self-setting compound could also be introduced with a low compression pressure, the compression quantity being limited to approximately 1.3 times the theoretical quantity for filling a borehole.
- Fig. 2 a drilling grid for the dubbing of the soil behind the face is shown.
- the grid comprises four transverse rows with six piles each.
- the required dimensioning and the The spacing of the piles forming the dowelling, as well as their type, ie material properties, depend on the slope slope, the expected load and the respective soil properties.
- the stability of the floor adjoining the working face can be improved without the need for work in the track area.
- the horizontal dowelling of the dam 1 also results in a favorable distribution of vertical loads in the soil. If the floor is pegged with unreinforced grout piles or cement stone piles, then the demolition of the face is also unproblematic, since these piles can be broken off and removed bit by bit with the help of machines, which are usually used to dismantle the face.
