Definitions
- the invention relates to a steel-concrete lining for road and rail tunnels with an inner shell made of steel segments. Subway tunnels are also considered to be such tunnels.
- a tunnel is generally only expanded if the surrounding mountains are not stable.
- the most common type of construction provides that a shotcrete layer is first applied to the rock eruption.
- the shotcrete layer changes the flaking of the rock layers. This is also known as consolidation.
- the shotcrete layer forms a reserve for commonly used plastic seals.
- the plastic seals are applied after the shotcrete layer has been completed.
- the seals are made up of sheets.
- the lining with the seal is followed by the introduction of concrete reinforcements or reinforcing bars and / or mats.
- a formwork carriage is driven into the tunnel and the space between the waterproofing and the formwork carriage is filled with concrete. This is done in individual sections.
- the sections are usually up to 20 long.
- Panel construction is common in tunnels where there is pressing water.
- the panels are made of concrete and / or steel.
- Such constructions have not become established in areas with low water pressure or low water accumulation. This is due to the fact that concrete is still the cheaper building material compared to steel.
- the invention is based on the object of creating a new type of tunnel construction which takes account of the tensions occurring in the mountains and / or fractures.
- this is achieved by first seeding steel sheet segments with a gap of compliance in the tunnel excavation, then backfilling the steel sheet segments with concrete leaving a deformation cavity in the compliance area and stiffening the compliance area at least after the constructional section has been created and finally the steel sheet segments are sealed.
- the steel sheet segments advantageously form a protective roof behind which the crew and
- the canopy can follow the dismantling front at a short distance.
- the distance can advantageously be kept so small that the unsupported slope is reduced to a negligible amount.
- the steel sheet segment After pledging a steel sheet segment, the steel sheet segment will be backfilled with concrete as soon as possible. This brings about the positive and positive locking of the steel sheet segment with the rock eruption. With a suitable early load-bearing strength of the concrete, pre-attachment can be used Mountain pressure has already been absorbed.
- this support is flexible. This is achieved through the resilience elements between the steel sheet segments and the support (e.g. the tunnel sole). The resilience elements allow the rock to be deformed. Behind this is the philosophy of creating a completely or partially self-supporting arch formation through mountain deformation above the tunnel. This relieves the tunnel expansion.
- the compliance in the area of the compliance elements requires a deformation cavity behind the compliance elements. Accordingly, the concrete is backfilled leaving the cavities free.
- the compliance elements then allow controlled compliance over the selected duration of their use.
- the compliance function may be interrupted if the breakout occurs for the bench.
- Steel sheet segments according to the invention which are supported on the tunnel sole by means of resilience elements, can in turn be used for the expansion in the rung area.
- the above-described interruption of the compliance function has only a minor influence on the settlement behavior or lowering behavior.
- the resilience can also be maintained during the stroke eruption.
- the deformation cavities can be kept open until any desired settlement behavior or relaxation of the mountains has occurred.
- the compliance elements are then stiffened. This is preferably done by filling the deformation cavities with concrete. That can e.g. B. done by injecting concrete milk. , "_
- the steel-concrete lining according to the invention with internal steel segments advantageously eliminates the need for an additional sealing measure if the steel sheet segments according to the invention overlap. Then the overlap areas can be welded together. Tensioning with the interposition of joint tape is also possible.
- the steel segments can be backfilled with concrete in various ways.
- One possibility is to blow the building material into the cavity between the steel segments and the rock eruption after the steel segments have been set up while being wetted with water.
- formwork can be dispensed with if the building material has an appropriate early strength.
- Another possibility for shaping the concrete segments according to the invention is to use face formwork.
- the building material can be hydraulically pumped behind the face formwork.
- the end formwork prevents the building material from flowing out of the cavity between the steel segments and the rock eruption.
- the deformation cavity provided in the area of the compliance elements extends from these compliance elements to the rock eruption.
- the cavity can also end at a distance from the eruption. In this case, however, the cavity is always chosen to be large enough to essentially maintain the resilience effect described above.
- Expansion is carried out either by changing the number of different segments and / or by changing the number of resilience elements.
- the expansion is also suitable as a modular system.
- the steel sheet has particularly high resistance to bending. It is also advantageous to provide the steel sheet with building material anchors or reinforcing bars, which both establish a connection to the building material segment and optionally also reinforce the building material segment.
- the resilience elements can consist of plates, between which deformation profiles are provided.
- the design of the deformation profiles can be designed mathematically and constructively exactly to the desired flexibility.
- concrete has been used as a building material in tunnel construction.
- the invention is not limited to concrete.
- the term concrete is intended to include all building materials in question.
- FIG. 5 shows a detail of the expansion provided according to FIGS. 1-4.
- Fig. 1 the outbreak for a tunnel dome and 2 denotes the bottom of the outbreak.
- the mountains are labeled 1.1. 1 consists of a steel inner shell 3 and a molded or backfilled concrete segment 1.2.
- the steel inner shell 3 is made of a corrugated steel sheet of, for. B. 2 - 5 mm thick.
- the inner shell 3 forms a sheet metal segment. Further sheet metal segments are arranged one behind the other in the longitudinal direction of the tunnel.
- shells with several sheet metal segments can also be used.
- the number of sheet segments in tunnels! Direction vary.
- the sheet metal segment 3 is provided with a number of evenly distributed building material anchors 3.2.
- the building material anchors 3.2 are welded.
- the structural anchors 3.2 have a bend.
- the building material anchors 3.2 serve to secure the connection between the segments 1.2 and 3 or to establish a connection.
- two supports 4 in the form of concrete strip foundations are produced in the area 2.
- the inner shell 3 is placed on the support 4.
- the inner shell 3 is supported on the supports via resilience elements 5.1 and 5.2.
- the inner shell 3 is introduced by means of a suitable removal platform or a front loader redesigned as a removal tool.
- the forehead area between the inner shell 3 and the mountains 1.1 is closed with a front formwork. Furthermore, the cavity 6 is kept open behind the resilience elements with the aid of a suitable formwork body. Suitable formwork bodies for the cavity 6 are, for. B. inflatable pillows.
- the cavity is filled with concrete, so that the concrete segment 1.2 is created.
- the sheet metal segments 9 have resilience elements, which are designated here by 12 and are supported on the tunnel sole.
- a deformation cavity 13 is created behind the resilience elements 12.
- the deformation cavity 13 is produced like the deformation cavity 6. Then the cavity behind the sheet metal segments 9 is crumbled with concrete. At the same time the
- Deformation cavity 6 closed, since the concrete encloses the compliance elements 5.1 and 5.2.
- FIG. 1 and 3 show two flexibility phases, the flexibility phase according to FIG. 1 corresponding to the working progress in tunneling in the exemplary embodiment to max. limited to three days. During this time, significant mountain tensions have been balanced.
- the flexibility phase according to FIG. 3 can be long as desired to ensure that an optimal rock formation has been achieved by yielding.
- the deformation cavity 13 is crumbled with concrete. This is preferably done by spraying concrete milk.
- the deformation cavity is closed with a corrugated metal strip 15 according to FIG. 4.
- the sheet metal strip 15 overlaps the segments 9 at 16.
- a sole plate 17 is provided in the sole area.
- all sheets 3, 9, 15 and 17 can be welded together.
- the resilience elements 5.1, 5.2 and 12 consist of M-shaped or W-shaped deformation profiles 18. The number of deformation profiles and their dimensions can vary. The flexibility of the flexibility elements can thus be set as desired.
- the deformation profiles 18 and the plate 11 consist of the same steel sheet as the segments 3 and 9.
- other formwork bodies can also be used.
- the bodies can form a lost formwork, i. H. the bodies remain in place.
- the bodies for the formation of cavities are also made in one piece with the resilience elements or are molded onto them.
- the molded body forming the cavity can, for. B. ent ⁇ by a sheet metal bulge.
- the compliance elements are provided with reinforcement bolts that improve the anchoring of the compliance elements in the concrete.
