has flat flat sides Uassereintrittslb'cher and on one narrow side or two opposite narrow sides is open and at least on the two an open narrow side adjoining opposite narrow sides has a longitudinal profile, which allows such narrow sides of two drainage bodies arranged next to one another to engage with one another.

Such drainage walls are known as moisture insulation of walls from the surrounding soil. Through the water inlet holes on the flat side of the drainage wall facing away from the wall, the water from the soil surrounding the tusks enters the drainage wall and is drained downwards inside. The facing towards the wall to be insulated flat side of the Dränagewand is closed _v so that the water is kept away from the wall.

A well-known drainage wall consists of two corrugated plates, each of which has its Uellen peaks facing one another connected to one another, for example spot-welded. However, this known drainage wall must be

have a width corresponding to the length of the wall, which makes them unwieldy if aia form a continuous insulation target. Flocks of individual partial walls combined to form a drainage tape} there is a risk that at the dividing lines Uasser reached the masonry. Besides, this one is well known Drainageuand isn't too pressure-resistant if it's not one has a relatively large wall thickness, which is expensive in terms of material.

The well-known drainage area outlined at the beginning runs out if conventional precautions »to remove bulk material between the earth and the wall to be isolated. Thus here is a gradual penetration dee soil Lw the bulk material is avoided, this is encased in a rectangular plastic container flaonen, uobei the outer container wall with Uassereintrittslöoharn combine iit "Several such containers are put together to the Dränagewand. For this purpose, the container walls forming the braided sides of the container protrude alternately over the hollow narrow sides of the container and are angled hook-shaped towards the other flat side so that neighboring containers can be hooked with one another

the drainage tape, which are anainandergienzendsn container but not held together across the wall, so that aie bsi not yet heaped up on their outside The ground can fall over. They must also be known Container for receiving the bulk material saint relatively thick

In contrast, the invention creates a kit of the type mentioned at the beginning for the hardening of drainage walls aua individual drainage bodies that _{can be joined together f} which are held together in the longitudinal direction of the Uand and across it, can have relatively small dimensions across the Uand and are sufficiently pressure-resistant when the wall is even thick.

This is achieved according to the invention in that the inside of the box is divided into a plurality of channels by stiffening ribs running parallel to the longitudinally profiled narrow sides and that the longitudinal profiling is form-fitting,

"Form-fitting" means in this context that one another Drainage body on the longitudinally profiled

Narrow sides so across to the flat sides, as well as across to the longitudinally profiled on narrow sides are fixed to each other. Drainage bodies arranged next to one another can therefore only be pushed into one another along the longitudinal profile. Because of the longitudinal profiles, there are grooves with the groove base Increasing width and engaging in the grooves tongues formed with compared to the spring back narrower Federuurzel.

"Form-fitting" in this context does not necessarily mean that the interlocking longitudinal profiles with each other must not form any longitudinal gaps. To compensate for manufacturing tolerances, there are rather narrow longitudinal gaps between the interlocking longitudinal profiles desired. Such gaps form a labyrinth seal between adjacent drainage bodies, so that despite the gaps a there is sufficient water tightness.

The drainage bodies according to the invention can advantageously transversely measured on their flat sides relatively narrow, so be plate-shaped, where they through the Uahl a correspondingly small spacing of the stiffening ribs from one another can still be made sufficiently pressure-resistant can, even if they only have a small wall thickness. Drainage body according to the invention can therefore easily be so that they are handy. They are particularly suitable for production using the extrusion process. Any number of inventions Drainage bodies can be made according to the length the wall to be insulated are put together like a sheet pile wall.

In the kit according to the invention can dßiartijß drainage body of different widths, so that the total width of the drainage area composed of them is adjusted to the specified length of the wall to be insulated. Preferably, however, are in the kit Drainage body present, which are yatailt parallel to the profiled narrow sides at at least one point, with in the area of division their oeiden, the Flachaeit-in forming Uands can be nested. As a result, the non-divided drainage bodies can be designed with the same dimensions be. Nevertheless, the total width can be omitted the drainage bodies assembled by means of a or several inserted, divided and nested drainage bodies vary.

Be var ^ Andes are in the ineinanderschiebboren area and stiffening ribs, so protrude these advantageous jeueils only won one of the flat sides forming Jände off and already terminate in such a distance in exerts opposite uand that inserted the corresponding flat side of the anderan part body into the remaining free gap u / can earth.

The longitudinal profile of the drainage body can, for example from one that is open to the narrow side in question

on one and one from the facing narrow side dee other adjacent drainage bodies may be formed by a spring · However, the length profile is preferred the drainage body on at least one narrow side of a groove open to the one flat side and one to diaser Narrow side of the groove delimiting »formed to this complementary tongue. This not only enables a good mutual interlocking of adjacent ones Drainage body, but also the identical design of the interlocking longitudinal profiles of adjacent ones Drainage body.

It can be useful if the respective spring back is at the same level as the neighboring flat side. Then adjacent drainage bodies are offset from one another, so that every second drainage body at a small distance of the duration to be isolated is arranged. This lets A possibly desired ventilation of the rough can be achieved * For a flush line of the drainage bodies However, the distance between the bottom of the groove and the groove is not enough on the flat face to which the groove is open, the distance between the back of the tongue and the other Flat side corresponds. With an identical formation of the interlocking longitudinal profiles, this means that

the specified distance of the groove base and correspondingly the specified distance of the back of the tongue from the respective one Flacihaeite must be greater than half the width of the longitudinally profiled narrow side of the drainage body.

Uenn both longitudinally profiled narrow sides of the drainage body are open to the same flat side, must in the kit such drainage bodies, in which the water inlet holes in the wall forming one flat side, If other such drainage bodies are present, in which the water inlet holes are formed in the wall forming the other flat side, so that the water inlet holes for adjacent drainage bodies are arranged on the same flat side However, the presence of such different drainage bodies in the kit can be avoided, unless of the two Grooves formed on a drainage body with tongues delimiting them towards the associated narrow side one groove is arranged to be open on one flat side and the other groove on the other flat side. Zuei Such drainage bodies can then be turned with the Ulass inlet opening pointing to the same side each other drainage body by a parallel to the longitudinal

profiling v / running axis are attached to each other. Diaae possibility of adjoining drainage bodies to be designed identically, facilitates storage.

Drainage body, the longitudinal profile of which on a narrow string from a groove open towards one flat side and one delimiting the groove towards this narrow side Spring is formed also allow a relatively simple design of a corner connection in which the adjacent drainage bodies abut each other vertically. For this purpose, the kit preferably contains a number of Dranage bodies are provided in which only one longitudinal profile has the groove, whereas the other has Longitudinal profile from a complementary to the groove Spring is formed, the back of which runs parallel to the associated longitudinally profiled narrow side.

In order to bridge the wall projection, which is as wide as the drainage body, there can also be drainage bodies in the kit, the two longitudinal profiles of which are formed from a tongue complementary to the groove, the back of which runs parallel to the associated longitudinally profiled narrow side. These springs are preferably arranged offset to one or the other flat side. Here, too, it is preferred that one such spring is adjacent to one flat side and the other of these springs is adjacent to the other flat side.

To achieve the form-fitting connection of adjoining Drainage body, the cross section of the longitudinal profile can have any suitable shape. Dia preferred Cross-sectional Jbrm, however, is that each groove and accordingly each complementary spring have the cross-section of an oblique trapezoid. For the outer tongue and groove existing longitudinal profile, this means that the crooked trapezoidal string in each case on that of the respective longitudinally profiled The side of the groove facing the narrow side or the flank facing away from this narrow side of the fader runs.

So for a corner connection Bin flush with the

the drainage body forming the corner is achieved with Advantage one flank of the one with your back parallel to the assigned longitudinally profiled sole side a drainage body extending spring bounded by one flat side and the other, the aohiefa trapezoidal side forming flank with its edge delimiting the spring root around the width of the spring rokena, and with its the edge delimiting the spring back is arranged at a distance from the other flat side by the width of the spring root. They then have a corresponding dimension Longitudinal profiling of the drainage present in the kit « bodies, which consist of a groove open to a flat string and a tongue that delimits the groove on this narrow side and is designed to be complementary to this *

If the height of the wall to be insulated is only small, it is recommended that it be parallel to its longitudinal profile to make the measured height of the drainage body equal to or slightly greater than the height of the wall. However, it is the height of the wall large, it is preferred to arrange a corresponding number of drainage bodies according to the invention on top of one another. These are In the kit, it is advantageous to use hollow junction boxes with two Opposing open narrow sides are present, which in the facing open narrow sides one on top of the other adjacent drainage bodies fit in, where-

with biloenden in the flat sides of the junction box Walls perpendicular to them the open narrow side & n the junction box forming the edges of slots at a distance the stiffening ribs of the drainage body with at least the rib thickness corresponding slot width are trained. Know through solohe connection box the drainage bodies arranged on top of each other are stably connected to one another, where the in the drainage body fitting connection box with its slots The ribs of the drainage body encompass and are thus supported in a fixed position on them «For in the above-described Drainage bodies with a split design are included in the kit preferably divided at at least one point perpendicular to their flat sides and in the area of both of them their] / flat sides forming walls provided connecting boxes that can be pushed into one another ·

If the connection boxes are designed so that they only fit loosely into the drainage bodies arranged one above the other, it can happen that undesired soil falls into the drainage body. In order to avoid this, outwardly protruding ribs can be formed on the flat sides of the connection boxes parallel to their open narrow sides in the middle between these,

in each of the sides facing the open narrow sides a groove-shaped longitudinal slot with the thickness of the Flachaeitan of the drainage body forming walls corresponding Slot width are formed. Such ribs overlap the edges of the drainage bodies arranged one above the other and cover these edges to the ground. The ribs of the junction box facing the wall can also serve as spacers for the drainage tape towards the tusks.

The water diverted through the drainage river can be more common Way into a drainage pipe running underneath the wall to be derived «For this purpose, according to the invention Kit preferably channel-shaped drainage boxes, which are provided with two parallel webs running in their longitudinal direction, which form an open channel form into which the open narrow sides of the drainage bodies fit, with the channel bottom from one of the The interior of the drainage box is formed limiting the grate, the bottom drainage body can be placed in such channels be placed in it, being supported by the grate. Such drainage boxes can go along with you pipe sockets distributed along their length, which allow the drainage of the water from the septic tanks into a

Allow drainage pipe running parallel to it.

The finished drainage wall is smoothly attached to the top Edge covered. If necessary, the uppermost drainage body can be designed to be closed on its upper narrow side for this purpose S8in. It can also cover these narrow sides over the open narrow sides of the uppermost drainage body Attach the rain bar to the masonry. Preferred However, U-shaped cover strips are available in the kit in cross-section, the U-legs of which are the drainage bodies fit in with their open narrow sides.

The face of the earth after the drainage was built, Flat side provided with the water inlet holes the drainage body is preferably formed grooved, the grooves with l / orteil parallel to the Longitudinal profiles run. Such a grooving prevents a full concern of the soil and thus a covering of the Uasseintrittslocher by the ground, so that the drained seepage water or groundwater can easily enter the drainage wall.

It can be seen from the above that a kit according to the invention designed drainage bodies with a
