You will need
- sledgehammer or grandma for hammering;
- - drill or drilling rig;
- - concrete solution;
- - sand;
- - fine gravel.
On light or sandy soil to install small posts, use the normal hammer. Place the pole upright and, holding his hammer, until he is sufficiently developed.
To facilitate the work, use the tailstock, is made of larger diameter pipe and welded on the one hand a plug, here, take a weight of lead or metal. The side weld of the handle. Put the pipe on the pole, vertically mounted, lift by the handles and drop down.
To set large poles, or purchase a special drill book the drill rig. Drill with it, well a little below the depth of soil freezing, pour a bed of sand. Next, install the inside the post and fill the remaining space with concrete or cover with soil and tamp.
After pouring the concrete mix into the hole a bit and raise the pole. In this case the bottom part is also closed by a layer of concrete that will protect the wood from rotting and metal from rusting.
In sandy soil you can do without a fill and compaction, simply drill the hole just under the diameter column. In this case, be careful that the hole was vertical and located strictly in line.
Heaving clay soils with a high level of occurrence water use the following method. Drill out the hole obviously wider than the column diameter and deeper groundwater. Complete the back of the hole with fine gravel and sand so that there is sufficient depth for immersion of the third pillar.
Tamp the drainage and install a pole. The space around the column fill with fine gravel, sand, and tamp thoroughly. With this method of installation, the groundwater will be free to go down and can't push the pole out of the ground, he will stand firmly and not mowing over time.
