Abstract

The barrier i.e. flood protective wall (1), has multiple columns (3) arranged in a longitudinal direction of the barrier in a distributed and spaced to each other manner, where the columns support a flexible waterproof membrane (2). The columns are anchored in earth (7'). The membrane has an edge strip (20) that extends over an entire length of the barrier. The edge strip is attached to the earth in a sealing and load-carrying manner. The columns are fixedly connected with the waterproof membrane and anchored in the earth about a swivel axis in a rotatable and articulated manner. The membrane is made of a plastic or natural rubber material such as styrene-butadiene rubber (SBR) and ethylene propylene diene M-class rubber, where a reinforcement filler contains a glass fiber, plastic fiber, or metal wires.

Description

introduction

The invention relates to a water barrier, in particular a flood protection wall, which can be transferred from a rest position in which no shut-off or protective function in an operating position in which the water barrier allows a damming height of located on a storage side of the water barrier water level, the damming through a height difference is defined between a lowest point of a crown forming the upper end of the water barrier and a reference level of a floor below the water barrier, wherein the water barrier can be transferred from the rest position into the operating position by a pivoting movement about a pivot axis extending in the longitudinal direction of the water shut-off.

State of the art

Such a water barrier is through the DE 30 01 010 A1 known.

In the field of water barriers and flood protection, a distinction is made between mobile and stationary facilities. While the mobile devices can be completely removed and temporarily stored in storage locations until they can be used at a time when they are not needed, stationary water shut-off and flood protection devices are always located at their intended location. In the stationary devices can be distinguished between those who are always in their operating position and thus can not be transferred to times when they are not needed, in a typically optically less conspicuous and space-saving rest position. Such non-changeable devices can generally be made comparatively simple and robust, as can be dispensed with moving parts and drives. In contrast, stationary devices with the possibility of a change between an operating and a rest position are usually used where, for aesthetic or functional reasons in the times in which the shut-off or protective function is not required, an upright position is not tolerable , This is especially true for waterfront promenades, which are committed for example by pedestrians or also for barriers in the area of traffic areas, which must be used regularly and where a barrier is temporarily accepted for protection purposes, for example, during floods. Basically, with water barriers according to the present application not only protection against floods be reached, but they can also be used as general stoppers in channels, rivers, basins or containers or as barriers against flowable media of all kinds (eg contaminated rainwater or fire water).

While in the transfer of the water barrier from the rest to the operating position or vice versa in principle all possible forms of movement, e.g. Displacement in vertical and / or horizontal direction in transverse or longitudinal direction of the water barrier, but also a rotational movement or a combined movement of the aforementioned basic types is conceivable, in particular a pivoting has been found to be practicable, since in this way from an erected Position easily a rest position with horizontal orientation of a formed by the Wasserabsperrung component level can be achieved.

Known stationary Wasserabsperrungen with pivotal mounting about a horizontal pivot axis usually consist of plate-shaped metallic elements, which at their end faces against each other and on a base side opposite the ground, i. typically a concrete made foundation or even a metallic substructure or other types of structural subsoil must be sealed. The known constructions are technically complex and therefore relatively expensive and also complicated in terms of ensuring the tightness in the area of shock and contact points.

task

The invention is based on the DE 34 01 010 A1 the task of proposing a water barrier, especially a flood protection wall, which is characterized by its simple structural design and can be produced at low cost in order to produce economically even in applications with long lengths can. In addition, a very reliable seal should be achieved in a simple manner.

solution

Starting from a water barrier, in particular a flood protection wall, of the type described above, the underlying object is achieved in that the water barrier of a flexible waterproof membrane and this distributed in the longitudinal direction of the water barrier distributed and spaced apart supports, which anchored in the ground or can be anchored, with one over the entire length of the water barrier extending edge strip of the membrane sealing and resulting from the dynamic pressure forces is receiving connected to the ground. Due to the flexibility and thus mobility of the membrane, the water barrier according to the invention can very advantageously absorb dynamic loads and impact energy, as they are exerted by moving water on the side of the jam. In addition, the membrane is easily adaptable to predetermined structures due to their flexibility, so that readily curved geometries in the longitudinal course of Wasserabsperrungen can be realized. The at intervals of about 1 m to 5 m (depending on the damming height), preferably between 2 m and 3 m mutually arranged supports that can be locked in their operating position, give the diaphragm and columns existing construction the necessary rigidity against deformation, the otherwise caused by the water pressure. The water barrier according to the invention may be stationary, but may also be carried out on the move and built up only temporarily for one-off operations (extinguishing water barrier) or temporarily during a flood season and otherwise housed elsewhere.

For larger storage heights (over approx. 40 cm), it makes sense to connect the supports firmly to the membrane and to anchor the supports in a swiveling manner about the pivot axis in the ground. By such a composite, the stability of the overall construction is significantly increased and eliminated the risk of lateral displacement of the membrane relative to the supports or individual supports.

The membranes can in particular be made of the usual rubber-elastic plastic materials such as SBR or EPDM and have a thickness of about 4 mm to 40 mm, preferably about 5 mm to 30 mm. The known materials, which are used for example for conveyor belts or in the field of hose weirs, are characterized by their robustness, durability, good UV resistance and great variability in terms of adaptation to optical specifications, such as special color or surface texture, out. The water barrier according to the invention is therefore suitable for a flood protection walls with a length of several 100 m, but also for the area of a seal, such as a garage entrance, for example, between two right and left side walls adjoining and a width of only eg 3 m. Such a flood protection wall would be erected only in case of flood and otherwise run over easily or be committed by their flat resting on the ground membrane, which can be sunk in the rest of the surface covering the garage entrance, of vehicles and pedestrians. If desired, the membrane may be covered in the rest position of the water barrier with a protective cover, for example in the form of metal mesh, wood panels or Riffelblechen.

According to a preferred embodiment of the invention it is provided that the crown of the water shut-off is moved during the pivoting movement from the rest position to the operating position of a dry side in the direction of the storage side. The reservoir height of the water barrier according to the invention should typically be between 0.1 m and 1.0 m.

A particularly reliable and robust way of sealing the membrane to the ground is to use a metallic clamping rail consisting of a section in the longitudinal direction of the water barrier or composed of a plurality of sections, each section preferably cooperating with a lower rail and the membrane between the lower rail, which is non-positively and sealed connected to the ground, and the clamping rail is clamped by means of these penetrating screws. Such a fastening technique has long been known in the field of hose weirs and has proven very well there.

In order to avoid unnecessary, possibly damaging (corrosion, pollution, etc.) influence of the water on the supports, the latter should be arranged on the dry side of the water barrier. In addition, the water shut-off should be inclined in the operating position with its crown on the dry side in order to obtain the smallest possible pivoting angle during the transfer from the rest to the operating position.

In order to minimize the damage caused by the water shut-off in the rest position, the water shut-off should be parallel to the rest position Surface of the soil to be aligned on the dry side of the water barrier, in particular horizontally.

A risk of tripping pedestrians and unwanted shocks when passing over the shut-off in the water position can be avoided if the facing in the operating position of the storage side surface of the membrane in the rest position of the water barrier is flush with the surface of the soil on the dry side of the water barrier. If a protective cover is provided above the diaphragm in the rest position, the criterion of flushing should be met in the condition of the protective cover applied.

Basically, the transfer of the water shut-off from the rest to the operating position and vice versa manually, i. in particular by means of human muscle power. A more comfortable and almost indispensable for large storage heights or jam lengths alternative is that the water shut-off by means of at least one operable with external energy or by means of an energy storage hydraulic or pneumatic drive, in particular at least one each acting on the supports piston-cylinder unit, from the rest position can be converted into the operating position.

In order to continue to fulfill the criterion of flush placement in the rest position with such a design of the drive, each drive and the associated supports should be sunk in the rest position and thus protected in each case arranged a recess, wherein the supports facing away from the pivot axis end portions support a support on one of the water barrier facing away from the edge of the recess. Thus, while in the areas between the supports the membrane can rest directly on the ground, the supports are recessed in the rest position including the associated drives and thus hardly appear ugly. They are also protected against unwanted manipulation by unauthorized persons.

A particularly advantageous embodiment of the invention is that the piston-cylinder unit associated with a support in the transfer of the water barrier from the rest position to the operating position of a push rod which couples a piston rod of the piston-cylinder unit with the associated support of a Rest position moves over a vertical intermediate position in an operating position or pushes, with the on the water barrier acting dynamic pressure pushes the push rod into its operating position and pushes the piston rod of the piston-cylinder unit in its retracted position or pulls in its extended position. In both aforementioned cases, therefore, the force caused by the back pressure does not act on the medium located in the cylinder space of the piston-cylinder unit, so that a continuous pressure maintenance is not required. Rather, the piston is either pushed into its retracted dead position or pulled out into the extended dead position, so that during the stagnation period not permanently the media pressure in the piston-cylinder unit must be maintained.

The supports should preferably consist of galvanized steel or profiles made of stainless steel with the greatest possible moment of resistance to bending and torsion.

Preferably, the membrane should be made of age-resistant, flexible, mechanically resilient, elastomeric materials such as rubber. SBR or - for particularly high demands - EPDM consist and to prevent excessive strains even at high water pressures a reinforcing insert of a net, fabric or threads, each consisting of glass fibers, plastic fibers or metal wires, especially stainless steel wires have.

In principle, the water barrier according to the invention can slightly rise at its lateral ends with respect to the middle region, so that the pivot axis, ie the level of the soil in this region, is arranged above the highest possible water level in a middle region. Since such a design due to the local conditions, where the water barrier is to be used, often will not be feasible and in particular connections must be made to existing structures in the range of vertical pads, the membrane with at least one lateral edge strip, which is approximately perpendicular to the Lengthwise of the membrane extends, sealingly connected to a projecting from a plane of the ground post. Such a connection can be done for example by means of a clamping rail or other screw or clamp connections. The lateral connections can be made only when the water shut-off has been transferred to the operating position, since a seal is required only in this position and the sealing connection precludes a lowering movement of the water barrier in the rest position, so that before lowering the connection to the post must be solved again.

To protect the upper edge of the membrane, which is particularly vulnerable to vandalism, a steel wire, for example, can be vulcanized into the membrane material, thereby preventing tearing or cutting with a knife. embodiment

The invention will be explained in more detail with reference to several embodiments of the invention water barriers in the form of flood walls, which are illustrated in the drawings.

One in the FIGS. 1 to 3 shown in their operating position flood protection wall 1 consists of a web-shaped about 20 mm thick membrane 2 made of a SBR rubber with a reinforcing insert of a polyester fabric and exemplified five connected to the membrane 2 by screws not shown supports 3. The supports 3 are in pivot bearings. 4 , which are arranged in alignment with each other and together define a pivot axis 5, stored in a base 7 'formed by a concrete foundation 6. In a ground-level and ground-parallel edge strip, the membrane 2 is anchored in the concrete foundation 6 by means of a clamping rail 7 made of a metal profile provided with holes. The anchoring is effected by means of a plurality of the holes in the clamping rail 7 and the membrane 2 penetrating screws. 8

In the area of the supports 3, the membrane 2 is also clamped in each case between the support 3 and one of the opposite side, ie the storage side 9 of the flood protection wall 1, ago arranged and screwed with the supports 3 through the membrane 2 through terminal strips, in particular in the FIGS. 2 and 3 are recognizable.

So that the supports 3 in the operating position shown their erect position in which they are at an angle 11 of about 50 ° with respect to a horizontal maintained, each support 3 is pivotally coupled to a push rod 12. At the opposite end of the articulated coupling with the support 3 of the push rod 12 is disposed in the operating position behind a lock 13, which prevents the support 3 under the back pressure of the oppressive against the membrane 2 water (the water level at maximum damming height is through the Line 14) is pushed away in the direction of the arrow 15. The pressure rods 12 thus form a locking of the supports 3 in the operating position.

As can be seen in particular from the Fig. 1 and 2 results in a top edge of the membrane 2 forming crown 16 in a wave-like line in the area between two adjacent columns 3 by a certain amount both downwards, and in the direction of the storage side 9 toward an opposite dry side 17 out sags. A lowest point S, which is typically located centrally between adjacent columns 3, limits a maximum dammed height H, which is defined as a height difference between the point S and a reference level B of the bottom 7 '. The in the FIGS. 1 and 3 The actual damming height (line 14) shown is slightly lower.

On the two narrow sides of the flood protection wall 1, the concrete foundation 6 each forms a post 18, the height of which exceeds the height of the supports 3 and the membrane 2 slightly. At the posts 18 in each case one in the direction of inclination of the posts 3 and the membrane 2 extending connecting rail 19 is secured to the side edge strips 20 of the membrane 2 are sealed, for example by means not shown terminal strips. This attachment can be done only after the erection of the flood protection wall 1 in the operating position shown and must be solved before a new lowering again.

Out FIG. 3 can be seen that both the push rod 12 and the support 3 are received in the rest position of the flood protection wall 1 in a correspondingly shaped recess 21 in the concrete foundation 6. The cross section of the recess 21 has for this purpose a step 22, on which an upper end 23 of the support 3 is supported in the rest position, so that the stored flood protection wall 1 in the rest position in the region of the supports 3 and the recesses 21, whose width is only slightly larger than the width of the supports 3 (see. FIG. 2 ), for example, can be run over by vehicles. In the areas between the recesses 21, the membrane 2 is in the stored state of the flood protection wall 1 directly on the concrete foundation 6 and is therefore just as easily for a ride.

In the FIG. 4 shown alternative embodiment of a flood protection wall 1 'differs from that in the FIGS. 1 to 3 shown embodiment in that for the transfer of the supports 3 from the rest position to the operating position shown, a pneumatic cylinder 24 is present, the cylinder-side end is pivotally connected to a holding profile 25 that in turn by means of screws 26 to the concrete foundation 6 'is connected. A piston rod 43 of the pneumatic cylinder is hinged to the support 3. The concrete foundation 6 'has in the embodiment according to FIG. 4 no approximately cuboid depression, as in the variant according to the FIGS. 1 to 3 but only a step 27, whose height is dimensioned so that the membrane 2 in the lowered position of the flood protection wall 1 'from its one end face 28 to the opposite end face 29 is flat and parallel to the plane 30 of the concrete foundation 6' , At the end opposite the clamping rail 7, the concrete foundation 6 'has a slope 31 sloping from the flood protection wall 1'.

In the variant according to FIG. 5 In order to lock the supports 3 in the operating position shown, a respective locking piece 32 is arranged at the end remote from the pivot axis 5 and is preferably welded or screwed to the support 3. A pressure rod 33 hinges on the one hand is connected to the concrete foundation 6 ", on the other hand is supported with its end face 34 on an end face 35 of the locking piece 32, so that the support 3 is fixed in the position shown. To be able to transfer the flood protection wall 1 "after the flood again in the rest position, the supports 3 are first a piece in the direction of arrow 36 to pivot so that the pressure rod 33 is free and parallel to the concrete foundation 6" can be stored, whereupon in a next step, the supports 3 can also be pivoted to a horizontal position.

At the in FIG. 6 shown variant of a flood protection wall 1 '''is the drive for raising and lowering the supports 3 by means of a located on the dry side 17 inflatable body 37, which has the shape of a Schlauchwehres and preferably extends over the entire length of the membrane 2, but in particular all Supported 3 backwards. The closed interior 39 of the inflatable body 37 can be filled with a liquid or gaseous medium to provide by its internal pressure the necessary abutment forces for fixing the supports 3 in the operating position shown. The membrane 38 of the inflatable body 37 has a substantially smaller thickness and therefore greater flexibility than the membrane 2 of the flood protection wall 1 '''. The sealing of the interior 39 of the inflatable body 37 takes place on the longitudinal side by means of two clamping rails 40 which are anchored to the concrete foundation 6 '"and between which both layers of the membrane 38 are sealingly clamped.

In the lowered state of the flood protection wall 1 '' 'the interior 39 of the inflatable body 37 is emptied and the two layers of the membrane 38 are parallel to the concrete foundation 6 "below the shown in dashed lines in the rest position flood protection wall 1' '' and are in close contact together.

In the FIGS. 7 to 9 Yet another embodiment of a flood protection wall 1 '''' is shown. The pressure rod 33 '''' is in this case provided at its end facing away from the support 3 with a rotatable roller 41, which can roll on a base 42 in the concrete foundation 6 '''' located depression 21 ''''. The provided with the roller 41 end Push rod 33 '''' is also hingedly connected to the front end of a piston rod 43 of a pneumatic cylinder 24 ''''.

In FIG. 7 is the flood protection wall 1 '''' shown in the operating position in which the piston rod 43 of the pneumatic cylinder 24 '''' is fully retracted. The pressure exerted by the water accumulated on the congestion side 9 (water level see line 14) is transmitted in the form of a compressive force via the pressure rod 33 "" to the piston rod 43, which is automatically held in its retracted dead position without any media pressure within of the pneumatic cylinder 24 '''' would have to prevail.

When transferring the supports 3 and the membrane 2 in the in FIG. 9 shown rest position, the piston rod 43 is extended, whereby the mechanism in FIG. 8 passes through shown intermediate position in which the push rod 33 '''' is vertically aligned. The inclination of the supports 3 is slightly steeper in this position than in the operating position according to FIG. 8 , Upon further extension of the piston rod 43, the supports 3 are lowered again in accordance with in the rest position FIG. 4 with its front end to a stop 44 of a housing 45 of the recess 21 '''' abut. The enclosure 45 may be used as permanent formwork in producing the concrete foundation 6 "". The width of the housing 45 is only slightly larger than the width of the supports 3 together with the laterally adjoining pressure rod 33 "", so that the membrane 2 in the areas between adjacent supports 3 directly on the surface of the concrete foundation 6 '''' rests ,

In the FIG. 10 an alternative flood protection wall 100 is shown, in which the membrane 102 is transferred by means of a mobile support 103 in its operating position. The mobile support 103 comprises a support strut 147 with a support foot 148, a push rod 112 and a tension strut 149, so that the support 103 as such already has sufficient stability. Immediately adjacent to a clamping rail 107, by means of which the membrane 102 is mounted on a concrete foundation 106, the concrete foundation 106 has a step 127, so that two different levels arise. The concrete foundation 106 has at its lower level in the area in front of the level 127, a quiver foundation 150 for receiving and anchoring the support leg 148, wherein anchoring can be done by appropriate means. While the support strut 147 is supported with its support leg 148 in the quiver foundation 150, the push rod 112 is at the lower level of the concrete foundation 106.

In the rest position of the flood protection wall 100, the mobile support 103 is not present and the membrane 102 lies flat on the concrete foundation 106, wherein it covers the Köcherfundament 150 and thus allows a walk. In order to transfer the flood protection wall 100 into its operating position, the membrane 102 in the area of the quiver foundation 150 must be raised and the mobile support 103 must be set up accordingly.

Finally, the show FIGS. 11 to 14 a final example of a flood protection wall 200 according to the invention, similar to that in the FIGS. 7 to 9 shown flood protection wall 1 '''' is constructed, however, can be erected by hand.

In the recess 221 of the concrete foundation 206 is again the verse with the membrane 202 e-hene support 203 and the push rod 233 housed in the rest position ( FIG. 14 ) are folded in such a way that a meeting of the concrete foundation 206 is easily possible. On the clamping rail 207 facing side of the recess 221 a recess 251 is provided for a mobile chain hoist 252 in the concrete foundation 206, by means of which the erection of the flood protection wall 200 is carried out. The chain hoist 252 comprises a tensioning chain 253, which is hooked into a designated, but not visible in the figures, eyelet on the top of the support 203, and a chain transmission with a crank 254, by means of which the remaining length of the tensioning chain 253 shortened and the Support 203 is erected.

In the FIG. 13 the situation is shown in which the chain hoist 252 is mounted and the tensioning chain 253 was just hooked to the top of the support 203.

When erecting the support 203, the roller 241 located on the end of the push rod 233 facing away from the support 203 rolls on the base 242 of the recess 221 until it reaches a stop 255. In this position ( FIG. 12 ), the roller 241 is fixed in position by means of a bulkhead 256. Now the chain hoist 252 together with tension chain 253 and crank 254 can be removed ( FIG. 11 ) and for the erection of another support.

Due to the high forces that arise in the erection of a support, it may be useful initially only partially erect the support 203 and then first partially erect the two adjacent columns using two other chain hoists 252 before the support 203 is completely erected.
