In a further embodiment of the invention it is proposed that since β θ the teeth of the tooth line are narrowed at their roots, so that they are essentially sohwal-

have a tail-shaped shape.

With this feature it is achieved that, with the help of the formwork shell, a basin structure is created from panels, which are clamped together, so that a connection of the plates with each other without regard to the durability the envelope is given and the flexibility of the revetment is maintained in the event of soil displacement.

Advantageously catfish are arranged to the Längseratreekung the toothing lines extending at right angles transverse connecting lines which have interruptions "so that the injected concrete can reach all of the divided SchalungsMO-le.

These cross-linking lines can also be used as lines be formed.

It is advantageous that the cross-connecting lines to the neighboring cross-connecting lines are offset by half® of your abutment

So that the flowable, hardening mass from an injection point on the formwork shell from all fields the formwork envelope reached, can between each

two cross-connection lines at least one interruption in the toothed line. By These interruptions in the cross-connecting lines and in the toothed lines are on the one hand a contiguous one Concrete wall achieved and on the other hand, it makes pouring the concrete slurry easier *

In particular, coloidal mortar, e.g. Colorete mortar, can be used as concrete. It is also possible, a hardening hate made of bitumen or artificial ' to use material with aggregates. A revetment is achieved with one formwork shell, which from individual at the connecting lines of the envelope νο, η-each other is composed of separate panels. The concrete is poured in via filling hoses, which are connected to nozzles of the formwork shell or via filling lances that are preferably inserted into the shell can be inserted through self-closing flaps.

It can be sent to the Steel cables also be attached to spacers, which additionally keep the ropes at a distance from their support.

To the Sohalungshüllen according to the invention on a To be able to hang gust, especially when If the envelopes do not extend to the bottom of the river or canal, it is appropriate, especially in the upper ones Arrange fields of the envelope wire mesh. The suspension is done in such a way that immediately after filling the When concreted through this wire mesh, a post is driven in, which attaches the formwork shell filled with concrete to the Soil staples. The wire mesh prevents this post from breaking out of the concrete slab.

In the following description, exemplary embodiments of the invention are explained, which are illustrated in the drawings. FIGS. 1-6 show top views of various formwork casings designed according to the invention and FIG. 7 shows a view along the section line VII - VII in FIG.

Ren wall 2 (see. Pig. 7), which are directly connected to one another, for example woven, at the two front edges 3 and along the side edges 4. According to the invention, the connecting lines on the side edges 4 Bowie between these side edges are designed as toothed lines 5 or 5 *. By this toothing lines 5 and 5 * is the bag-shaped casing is divided into sub Pelder> whose cavities 6 are separated from each other. • At right angles to the course of the toothing line 5 and 5 ¹ are also arranged cross-connecting lines 7, which, in conjunction with the toothing lines "5 and 5 ^1, divides the sack-shaped shell into regular hexagonal or square fields. Within each field there are nooh spacers 9, which $ the bulging of the

When laying the shuttering shell, the teeth 13 on the right edge of the shell engage in correspondingly formed indentations 14 on the left edge of the shell that has already been laid.

The casing covers are designed in such a way that the teeth 13 * can engage in the indentations 14 'on the other edge of the casing without being offset. In the case of a woven casing, the edge of the fabric runs straight through. Which Denden on the outer edges of the envelope through the teeth line bil not have to face grooved tissue on or

be cut out so that the teeth of the formwork shell to be connected can engage in the indentations of the shell already filled with concrete. While in the cases according to the Pig. 1 and 2, divided by the indentations 14 gores are cut along the lines 30, the corresponding gussets of the cut in FIGS. 3 to 6 dargßstellten cases. *

To several formwork cases adjacent to each other move to, the casing fastening means such as hooks are arranged 15 »to a rim 4, which cooperate with fastening means, such as eyelets 16, which the adjacent casing ■ are arranged respectively at the other edge 4 that the Teeth 13 each engage in the indentations 14 of the adjacent casing.

Interruptions 17, which are arranged in the cross-connecting lines 7, are used to introduce the concrete. Interruptions 18 can also be provided in the inner verging lines 5 »5 'so that all fields of a shuttering shell can be completely filled by one or more injection sites. In the example, naoh Pig. 3, the injection hose or the injection lance would have to be introduced at the three filling openings 19, 20 and 21 because the toothed lines 5 ¹ have no interruptions . Interruptions 17 and 18

In the interlocking lines as well as in the cross-connecting lines are the required properties of the revetment to be created according to frequency and size,

of the concrete used and the type of injection.

In the formwork shell of Fig. 1 1 and 2 steel cables 10 are arranged between the shell walls, the top end in a sole 11. With the help of these steel cables the casing and the concrete slab to be produced with it can be suspended from a steep slope will. The course of the toothed lines 5 and the Qiierverbindungslinien 7 is chosen so that of them · 'Hexagonal fields are enclosed - ^ and the cross-connecting lines adjacent fields are offset by half the distance between these cross-connecting lines.

In Fig. 2, the course of the toothing line 5 and the cross-connecting line 7 is chosen so that the joints of the revetment are straight in one direction only.

Even with the envelope according to Pig. 4 and Pig. 6 it is achieved that the plates produced in this way are each clamped to four adjacent plates. The cross-connection lines 7 ¹ are formed in accordance with the toothed lines 5 ¹ . In Pig. 4, two opposing, axially-tailed teeth 13 ^f and, at right angles thereto, two opposing, dovetail-shaped indentations 14 *, are assigned to each panel divided by these lines. This design has the advantage that no excessive weakening occurs in the corners of the panels to be produced with this casing. According to -Eig. 6 can also be achieved by the fact that each face also has two teeth and two indentations, but each tooth 13 * \ is opposite to a hollow 14 *.

The covers are, for example, 1.50 to 2.50 m wide and any, e.g. 10 or 20 m long, and the width and length of the panels produced in the panels of the casings is about 50 to 70 cm.

For the formwork shell, naoh Pig. 5 are arranged in individual Pelder between the walls of the shell wire mesh 22 to. Before the concrete hardens, 22 piles can be driven through this wire mesh , so that the sohalunhell and thus also the concrete slab boir.piela-. vti ·· an «intr put embankment can be hung.
