The erection of landmarks when marking off plot boundaries represents only one of the working phases, which can take up a rather good deal of time, especially, when using classical landmarks, souch as concrete columns or worked stone. Transport represents a big problem – not only the transport to the working area, but also the transport within the range of working area. The burial of classical landmarks is considered to be time-consuming. Therefore, talking all the above mentoned facts into consideration, it is definitly more convernient to use modern landmarks.
LANDMARK Z-1422 CONSISTS OF AN ANCHOR, WHICH IS MADE OF HIGH – QUALITY STEEL (Ø 13 mm), COATED WITH POLYETHYLENE PLASTIC MATERIAL (Ø 12 mm), AND A HEAD, WHICH IS EITHER PLASTIC OR CONCRETE – PLASTIC.
Plastic coating prevents anchor from rusting, and at the same time, due to its form and compositing, it enables optimal anchoring, which results in long duration of a certian landmark.
Anchors are manufractured in three different lenghts and it is possible to combine them with different caps. Landmark’s cap is made of highly resistant polyethylene plastic material PL-LD, which is insensitive to impact, temperature changes and to the radiation of ultraviolet rays. The cap of MB and MAC type is a plastic cap, filled with AB concrete. The use of landmarks is very simple, as a hammer is the only thing you need for placing.
There is a standard inscription on the cap when using landmarks for making off property boundaries. LANDMARK, DESTRUCTION OR ARBITRARY MOVEMENT IS PUNISHABLE, the colour of the cap is yellow. However, if a landmark is used as a (polygon) point, then the inscription says: GEODETIC POINT, DESTRUCTION OR ARBITARY MOVEMENT IS PUNISHABLE, the colour of the cap is red. The colour of the cap, as well as the inscription on it could be changed at the request of a subscriber.
The S-300, S-400 and S-500 anchors are used to stabilize the heads shown above.
BEFORE THE POINT IS STABILIZED, WE LEVEL THE GROUND TO MAKE SURE THE HEAD RETAINS ITS SHAPE OR TO PREVENT THE HEAD FROM CRACKING.
