The stabilizing device is prone to bending outwards of plate material specifically when driving the device into the ground and during use when the device is subjected to severe lateral loads caused by canting of the load element, in this case a pipe.
  • The invention further relates to an assembly of a ground anchor having a load element and a stabilizing device.
  • The invention further relates to a method for installation of an assembly of a ground anchor having a load element and a stabilizing device.
    • Summary of the invention
  • The invention aims to at least partly solve a problem associated with a known stabilizing device for a load element of a ground anchor.
  • Another object of the invention is to improve stabilizing device for a load element of a ground anchor.
  • Still, another object of the invention is to provide a stabilizing device for a load element of a ground anchor, wherein the stabilizing device has an improved strength.
  • Yet another object of the invention is to provide an alternative stabilizing device for a load element of a ground anchor.
  • According to a first aspect of the invention this is realized with a stabilizing device for a load element of a ground anchor, the device consisting of two plate members, wherein the plate members have a generally L-shape and are complementary and do form a generally cross shape when coupled together and when coupled together form a feed through sleeve for leading the load element there through, wherein each plate member comprises at least one recess surrounded by plate material, which at least one recess of each plate member receives a central feed through sleeve forming plate member portion when the plate members are coupled together for forming the generally cross shaped stabilizing device.
  • This provides the possibility of forming the sleeve by recesses surrounded by plate material that gives a much better performance under side loads when the load element is canted. In addition, the stabilizing device is more robust in connection with driving of the stabilizing device into the ground.
  • A stabilizing device for a load element of a ground anchor, specifically stabilizes the load element with respect to lateral loads such that the load element maintains its position when subjected to lateral loads. A load element may be an elongate tension member like a cable or a compression member like a rod or a pile depending on the type of ground anchor. Such an elongate load element couples the ground anchor with the load to be anchored. The elongate load element, when not stabilized, easily cuts through the ground when subjected to lateral loads and thus may leave its intended position, which is undesirable.
  • In an embodiment of the invention, the two plate members are similar, preferably identical. This makes the stabilizing more efficient in use and during transportation.
  • In an embodiment of the invention, the feed through sleeve is arranged centrally with respect to the stabilizing device.
  • In an embodiment of the invention, each plate member comprises a plurality of recesses, in a specific embodiment two recesses. This makes the stabilizing device even more robust because loads are better distributed along the height of the plate members.
  • According to a further aspect of the invention this is realized with an assembly of a ground anchor having a load element and a stabilizing device according to the invention, wherein the load element is fed through the central feed through sleeve.
  • In an embodiment of the assembly, the load element is coupled with the stabilizing device in a slideable manner.
  • In an embodiment the assembly comprises coupling means for fixedly coupling the load element with the stabilizing device once the earth anchor and the stabilizing device have taken their desired position.
  • In an embodiment of the assembly, the coupling means are provided with the upper and/or lower side of the stabilizing device for fixedly coupling the load element with the stabilizing device at the upper and/or lower side of the stabilizing device.
  • In an embodiment of the assembly, the ground anchor is a pivoting anchor. For a pivoting ground anchor it is even more beneficial to be coupled with the stabilizing device in a slideable manner because the load element needs to be taken in to deploy or set the pivoting anchor.
  • According to an even further aspect of the invention this is realized with a method for installation of an assembly of a ground anchor having a load element and a stabilizing device according to the invention, comprising the steps;
    • placing a ground anchor with a load element,
    • sliding a stabilizing device according to a preceding claim around the load element for accommodating the load element at least partly in the feed through sleeve,
    • driving the stabilizing device in the ground while sliding the stabilizing device with respect to the load element,
  • In an embodiment of the method the ground anchor is a pivoting ground anchor, and the method further comprises the step;
    • taking in the load element through the feed through sleeve for pivoting the ground anchor.
  • The invention further relates to a device comprising one or more of the characterising features described in the description and/or shown in the attached drawings.
  • The invention further relates to a method comprising one or more of the characterising features described in the description and/or shown in the attached drawings.
