Definitions
- the invention relates to an anchorage for wooden poles of any kind, especially for electric cables, especially overland electrical cables carrying wooden poles.
- electrical poles carrying wooden poles include a variety of networks, such as high and medium voltage networks of the RUs, which have to ensure the absorption of high mechanical loads, low-voltage networks, medium and small loads must cope, including for Telecommunications networks and radio networks; mention should also be made of power lines on railway lines, e.g. the German Federal Railways, which are exposed to high mechanical loads, even in changing directions, the u.a. Wind and suction forces of the passing trains result.
- the alternative products include steel or steel tubular masts, which are about three to four times more expensive than round timber poles and also require elaborate foundations, but can be used for a total of about 80 years; However, there are considerable maintenance costs due to corrosion protection measures, which are required in maintenance intervals of about 20 years. Steel masts can only absorb torsional forces much worse than wooden masts; in the event of overloading - as has recently happened on a large scale - the bending of the steel masts takes place.
- round timber pylons are still a very economical alternative, whereby the renewable raw material wood corresponds to the increased ecological thinking in modern economies with a favorable energy balance also in terms of their production.
- the sharp price increases and price fluctuations of steel that have emerged in recent years favor the market assertion and market expansion of round timber poles for the various applications.
- other mast geometries and timber mast constructions may also be used within the scope of the invention, e.g. from new wood composite materials with special technical and economic advantages, to which the following statements can be analogously transferred.
- the foundation of the wooden poles has been done in such a way that about 1/6 of the length of the wooden pole is installed in the ground.
- the mast length installed in the ground can be different due to different load-bearing soils, which leads to different mast lengths.
- the establishment of all types of mast is done by excavation and subsequent introduction of compacted layers.
- the traditional and common foundation method for round timber masts by earth installation includes both single masts and double masts (consisting of two single masts) and H-masts, consisting of two spaced apart single masts.
- the invention is therefore based on the object to protect wooden poles of the type mentioned before soft rot without environmentally harmful, toxic protective measures taken or become necessary.
- This object is based on the consideration to propose a foundation method independent of the action of the soil, especially the soil quality on the masts and on the basis of the general inventive idea to reliably anchor the respective wooden mast without ground contact, device by a preferably open at both ends, elongated hollow body dissolved, upright with his one, lower section in the Soil is held and its other, upper portion receives the mast base, as well as means for supporting the mast within the upper portion of the hollow body, to which the invention also proposes a method in which the hollow body rammed into the ground with supernatant, beaten and / or is drilled, then a drainage pack, preferably coarse gravel, is filled into the hollow body in the area of provided in the hollow body wall drainage openings is placed on this Drainagekies serialung the wooden mast, then introduced means for supporting the mast within the upper end of the hollow body For example, filling material in the form of a further gravel layer with respect to the first gravel bed of smaller grain size, namely 2 to 16 mm, preferably 5 to 10 or 8 to 12
- the proposal according to the invention has the enormous advantage and thus ecological charm that the use of polluting, highly toxic impregnants is no longer necessary while increasing the life of the mast - from 30 years to 40 to 45 years - and a relatively small amount of time to make the foundation , wherein with respect to the introduction of the hollow body according to the invention in the ground on, for example, from the oil handling technology known impact or drilling or Einwindtechniken as they are also used in gas handling technology, can be used.
- Another essential advantage of the invention is the reusability of the hollow body for at least one further rule useful life of a wooden mast for the then new to be used wooden mast.
- an exchange mast when using the foundation method according to the invention can be placed in the same place again, since the inventively established masts in their footing not mess up and the soil with Contaminate soft rot. Contamination of the soil with soft rot would prohibit the erection of a mast at this point.
- the cost advantage to be mentioned which results from the possibility of reuse of already installed and used in the network masts that are cut off after rotting above the ground and can still be used by the anchoring method according to the invention at least for a remaining useful life.
- mast exchange times are shorter, which is particularly advantageous if, for example, in power grids "working under voltage", so if the section of the pipe network, are exchanged in the masts, not turned off.
- the mast lengths required in the context of the invention can be kept substantially shorter compared to conventional anchorage proposed according to the invention, further cost advantages result.
- the bending moments occurring at shorter masts are lower, so that the mast sections can be reduced compared to conventional, embedded in the ground wooden poles.
- the transport of shorter masts is easier.
- eliminates the need for conventional masts aftercare, as well as measures to protect against theft or to protect against mechanical damage to the wooden mast and bandages can be omitted because the wooden mast is protected in its lower part by the hollow body.
- the invention leads to an extension of the test and maintenance intervals, ie less testing and maintenance, with the result of lower operating costs. In particular, this also eliminates the digging, checking and re-digging.
- the invention can in principle also be provided for wooden masts having a triangular, square, rectangular, polygonal or other cross-section and, for example. be made of wood materials or glued laminated timber.
- the hollow body according to the invention preferably has a circular cross-section, depending on the composition of the earth stratum, another cross-sectional profile can also be selected.
- another cross-sectional profile can also be selected.
- the material of the hollow body ductile cast iron, steel, reinforced concrete, fiber reinforced concrete and / or glass fiber reinforced plastics and impact-resistant ceramic materials in question. Especially proven is cast pipe DN400.

- Both the stability of the mast base and the drainage effect are particularly positively influenced by a capillary-breaking layer, in particular one-grained gravel, preferably with a grain size of more than 16 mm, on the ground by the ramming of the pipe in the soil compacted Erdreichpfropfen inside the tube.
- a capillary-breaking layer in particular one-grained gravel, preferably with a grain size of more than 16 mm, on the ground by the ramming of the pipe in the soil compacted Erdreichpfropfen inside the tube.
- the gravel layer extends effectively at least partially beyond the perforation height.
- the mast base In order to give the wooden pole during assembly as centric position and at the same time the mast base during assembly, especially when introducing into the pipe already give a certain grip and in any case a guide, the mast base according to another feature of the invention on his lower end face provided with a centering and support plate; this is nailed down or screwed on the underside of the mast base and preferably has an outer diameter corresponding to just the inner diameter of the tube and is designed as a perforated plate to avoid a drainage dam.
- the centering and support plate may also act as a separation between the capillary-breaking layer and filling material, and at least parts of the filling material can be lifted out of the hollow body when the mast is withdrawn.
- below the centering and support plate may be provided in particular from below at the screw heads bottom plate.
- the bottom plate can be provided with water drain holes and bolted to the centering and support plate.

Also, the plates may be coated, for example, with copper or zinc to better protect against corrosion, or also to achieve a fungicidal or biocidal effect in the mast base.
- a particular penchant of the invention is the idea of thereby introducing the loads occurring on the mast in a suitable manner in the soil and at the same time to ensure a drainage effect to avoid moisture formation on the wood, that the annulus between the wooden mast and the tube with a filler is filled, preferably in turn with a gravel, but with a smaller grain size of preferably 8 to 12 mm, whereby this bed both supporting and power transmission functions and filled after appropriate alignment of the mast by means of the mentioned straightening wedges in a simple manner in the annulus and there can be compressed.
- the annulus thickness, ie the distance between the mast and the tube is preferably at least 5 cm.
- a particularly advantageous property of the filler material in its insert according to the invention is that it self-adjusts or compensates for the dimensional changes of the wooden pole caused by shrinkage and swelling (due to moisture loss or seeding), without limiting the support force transfer function or even lost.
- This also results in the further advantage that the filler uniformly presses fungicidal or biocidal metal plates or - lattice, with which the mast in the foot area is partially or completely, regardless of how strong the mast has disappeared or swollen.
- the loads occurring on the mast can also be absorbed by at least three permanently arranged in the cavity between the hollow body and mast at a height, in particular near the upper edge of the hollow body, arranged clamping elements.
- the forces on engaging in the mast base dowel special design and screws transfers from the mast to the hollow body, the forces acting on a wooden mast forces can be sufficiently well introduced through the hollow body into the ground.
