The present invention relates to a ground-anchored foundation for a mobile flood protection.
With the risk of rapidly rising floods in densely populated areas, there are today an increasing number of areas that are exposed to being damaged by floods. This happens regularly in Norway and abroad, and every year floods causes great damage.
Conventionally, buildings are protected by sandbags. This is a time-consuming process that requires a large number of people to set up, and it is often not possible to erect a sandbag wall in time.
There exists mobile flood protection arrangements that can be set up by laying out prefabricated elements that are inserted into the ground, as described in WO 2004/016860 A1. The disadvantage of such flood protection is that it is not securely anchored to the ground, as it cannot withstand horizontal and vertical forces, and will therefore succumb to high water pressure. A solid ground anchorage is therefore essential for a safe and well-functioning protection against flood.
Other prefabricated flood defenses, such as described in NO 20170313 A1 and EP 236513 4 A2, use boxes with retractable elements buried in the ground. Such a solution is not favorable as one must have a framework dug down. This means that the complex framework comprising movable parts lying in the ground for years, where it will be subjected to deteriorate. The installation costs of such a solution will also be substantial.
Therefore, there is a need for a quick-built flood protection that can be quickly set up at various heights and on uneven grounds at different levels, securely anchored to the ground and which is inexpensive to install.
With the ground anchoring arrangement of the present invention described herein, the disadvantages and limitations described above are avoided and further advantages are obtained with the invention as described with the features set forth below and in the claims.
The present invention provides a device for use with other flood protection equipment, more specifically, a combination of equipment which enables rapid construction and anchoring of a mobile flood protection arrangement. In order to quickly set up a flood protection, a ground-based foundation for a mobile flood protection is disclosed herein, wherein the ground-anchored foundation comprises at least one bottom anchor cylinder, wherein the at least one cylinder is attached to a plate, the plate being centered to the at least one cylinder, wherein the plate comprises a mounting hole adapted for pivotally attaching a receiver part to the mobile flood protection unit. The plate further comprises a protrusion jutting vertically upwardly, and where the protrusion has an upper end approximately flush or planar with the surface of the ground, and wherein the mounting hole is located in the protrusion a predetermined distance from the upper end of the protrusion.
In one embodiment of the invention, the cylinder is oriented approximately vertically upright or inclined.
In another embodiment, the invention comprises a second ground anchor cylinder in which the second cylinder is attached to the plate.
In a further embodiment, the plate is a vertical plate having a substantially rectangular body having a width and a height, and a protrusion jutting vertically upwards from the main part a predetermined height.
The second aspect of the invention relates to a mobile flood protection for attachment to a ground anchored foundation. Where flood protection comprises a receiver part, a vertical wall support pillar protruding upwards from the receiver part, a horizontally placed profile protruding approximately perpendicularly from the receiver part and which is bearingly supported on the ground at its free end, a support profile obliquely situated and fastened at a first end to the wall support pillar and at a second end to the horizontally placed profile. The wall support pillar comprises at least one fastening means, wherein a cladding plate panel is provided which is attached to the wall support pillar using the at least one fastening means, and wherein the cladding plate panel is adapted to withstand flood water.
In a preferred embodiment of the flood protection, the receiver part comprises a slit adapted for the protrusion of the plate, a hole adapted for a receiving a bolt, and a bolt. The bolt is adapted to penetrate the bolt hole in the receiver part and the mounting hole in the plate when the receiver part is positioned with the slit over the plate in such a way that the bolt hole and the mounting hole correspondingly coincide.
The third aspect of the invention relates to a method of anchoring a mobile flood protection foundation according to one of the claims , in the ground. The process comprises the steps of:
The fourth aspect of the invention relates to a method of mounting a mobile flood protection, in which a plurality of ground anchored foundations according to one aspect of the invention are arranged adjacent to one another, or adjacent to each other, at a predetermined distance in the ground. The method comprises:
For a better understanding of the invention, a set of figures is provided. Equal numbers on different figures describe the same traits.
The following invention enables an inexpensive, fast and secure installation of a ground-anchored foundation for a mobile flood protection arrangement. With the ground anchored foundations pre-installed in flood-exposed areas and around buildings, a flood protection system can be quickly set up by attaching a plurality of flood protection cements to the foundations when needed. The foundations will be ready for use for years without the risk of deterioration. If necessary, effective flood protection can be set up without a large number of people or expensive machines.
Compared to the prior art, the present invention is a safer, faster and cheaper solution.
When using words such as up, down, vertical, horizontal or inclined etc. this is always in relation to a foundation and a flood protection place on flat land.
In an advantageous method, the plate 1 is molded or cast in the cylinder 3.
The cylinder 3 and plate 1 is placed in the ground by preferred method. The protrusion 4 is optimally positioned when its upper end is aligned with, or in plane with the ground surface.
The clamp 19 can advantageously be used to hold profile bodies close together, where the different profiles form part of the mobile flood protection arrangement. The advantage is obtained by the fact that the connection is stepless and that the connection can be strengthened with multiple clamps 19 if needed. The clamp 19 is a strong and fast connected clamp that can connect two profiles to set up the mobile flood protection. Said profiles in the present embodiment may include all profiles shapes and elements that is comprises the mobile flood protection arrangement.
In order to anchor a ground-anchored foundation according to the invention in the ground in a cheap and fast way, one can first provide by digging or drilling, a hole in the ground. A time and cost-effective way to provide one or more holes in the ground is to use earth drills. The depth of the hole is determined by the required length of the cylinder 3 to obtain sufficient adhesion. Furthermore, at least one hollow cylinder is placed in the provided hole. This cylinder is preferably made of a hard plastic material. The cylinder is formed with a centered slit or recess at its upper end, the width and depth of the slit or recess is dimensioned so that it is adapted to receive a plate 1 to be placed in the slit or recess. Further, the hollow cylinder is filled with concrete up to the upper end of the cylinder and a plate 1 is placed in the slit or recess. The plate 1 can then be adjusted in the height and longitudinal direction to achieve the desired position. Upon curing or hardening of the concrete, the plate 1, embedded in the cylinder, is fixatedly fastened. In the stored, or unused condition, the visible part of the ground anchor is limited to only the top of the protrusion 4. This applies regardless of whether the ground level at its surface, such as asphalt, has different height levels or if the ground is a hill or hilly. The mounting mechanisms and the hole in the ground left from the ground anchors can be covered with a lid or other protective means.
Unique with pipe foundations is that several foundations can be built simultaneously and with the same work operations. Particularly favorable is this method of measurement for fastening wall supports, besides that all concrete labor can then be carried out on several foundations at the same time.
The cylinder 3 may be positioned at an oblique or inclined angle down in the ground to resist the forces acting in a vertical direction upwards from the ground. An inclined cylinder 3 will be blocked from being pulled straight up by the ground or earth above it. Such upward forces may occur if the flood water is high on the cladding plate panel 11. The ground-anchored foundation will also be subjected to horizontally directed forces from the water pressure. A sufficiently long cylinder will withstand the horizontal forces. With a mobile flood protection arrangement attached to a ground-anchored foundation as disclosed, the inclined profiles get a vertically directed pressure and a high resistance to settling or sinking in the soil or ground, when the arrangements stops the flood.
Although specific embodiments of the invention have been disclosed and illustrated herein, it is known that modifications and variations may readily occur to those skilled in the art, and accordingly, the claims are intended to be interpreted to cover such modifications and equivalents.
