All about drilling holes under the poles

Drilling holes under the poles – a forced measure, without which the extremely strong fence is not to build. Rabita grid with scored pillars – not the most reliable solution: part of the pillar, scored in the ground, rust over several years. Overhead part of the pillar, having lost his support, falls.

Peculiarities

Drilling holes for fences or supports for non-capital (non-residential) structures and buildings necessarily implies concreting of the underground part of the pillar. Concrete protects steel from which each such pillar is executed, from the effects of salts, alkalis and acids contained in the soil. He does not let the excessive moisture to the post. For this, you need wells (pit) – for each of the columns.

Carry out manually drilling holes (with a welding) difficult. To drill several holes in the ground for an hour, rather than dig a one and a half or two hours one of them, use the drive or gasoline motor block, leading the gate to rapid rotation. He also will try a deep canal for a water well for a few hours. Drilling is carried out strictly vertical.

No distortion to any of the parties is allowed: “Chushka”, cast from concrete, with a pillar in the center will acquire a shift of the center of gravity, why the pillar will noticeably glance at time, devastating from the vertical position.

Than you can drill?

Manual drilling – extreme measure with full and long-term lack of access to mechanical booms. The simplest option is the hand-made garden bob, manufactured by independently in just a couple of hours. It is equipped with a T-shaped handle, rotating it, the worker will gradually plunge into the ground. If drilling to a depth of more than a meter is needed, an additional section is provided for the convenience of operation, attached to the handle and the working part of the boraxy. Theoretically, with the help of a manual drill and a large number of sections, you can not only drill the pits under the poles, but also to get to the groundwater, locating at a depth of up to 40 m – provided that the mass of all sections does not prevent one person to do the channel of such depth, and the density Soil is not exemplary.

Mechanized yamobura are divided into fuel, electrical and hydraulic. The first are equipped with an internal combustion engine, creating an acceptable torque for efficient drilling, due to the burning of gas, gasoline or diesel fuel. Based on the second – electric drive from 2 kilowatt. Third belong to the professional instrument: the hydraulic drive of the Yamobur is most often installed on the mobile (automotive) platform with additional landfills that prevent rocking machine with a quick start and sudden stop.

In some cases, the hydraulic rotator lift is installed on a special equipment, for example, on a converted excavator or tractor. Renting such equipment on the day or another, the consumer decides the question of digging pits under the posts around the perimeter (often more than a hundred) during the same period. Electrical enemus can be made on the basis of increased power perforator (from 1400 W). This mechanical means can cope with the drilling holes under the fence columns, supports for the utility room under construction. It will speed up the process of digging the wells for seedlings of fruit trees and shrubs.

By type of working part of the borants are divided into:

  • Simple gardening – The working part is assembled from two semi-tricks from the circular saw;
  • screw – the borne has a screw part made of steel strip, poured around the axis and put on the edge before welding.

The first are installed mainly on manual fixture. The second most often applied as part of a mechanized device, rotated not by the hands of the worker, but by the help of the drive.

Hole parameters

Chernozem and sampling soil is less density. Punching (as a result of long freezers) also makes its own adjustments to the depth and diameter of the well. In such a soil, the depth of the underground part of the pillar is at least a meter. Many owners of country houses, changing the old grid fence on a new (out of proftres and roofing sheets), plunge poles to level 1.4 or more. Suglly (or clay), as well as rocky (containing smooth stones or rocks of rocks) The ground eliminates the need to plunge pillars to the depth of more than meters. Common depth – 0.8-0.9 m.

The diameter of the wells greater than half the meter, for intake sections is impossible. The fence does not apply to the capital type of construction: only its weight is available on it, hundreds of times less than the weight of a small country house, and possible sailboat with a hurricane (flooring from the proflist resists the wind). The gate, combined with the gate, allow you to slightly exceed the diameter of the well, however, the user knows that the deeper and wider well under the post, the more concrete goes. Larger diameter, length and weight of concrete “Chuga” will allow to keep a post for decades, not letting it be born on a degree.

The height of the above-ground part of the pillar for the same fence – not more than 2 m. Higher fence makes sense to put if the object is not a cottage and non-country house, but a guarded structure, for example, an item or branch of GOSTONTOR, University, Hospital, military unit and t. D. Too low fence threatens a constant violation of the bandwidth received by the checkpoint. The distance between the centers of two neighboring holes (location of the columns) is chosen so that the fence does not break, did not fall, for example, due to frequent and strong winds in this area. For example, for pillars, which uses a square professional section with a cross section of 50 * 50 mm, and as a horizontal crossbar – a rectangular tube 40 * 20, the distance between two adjacent supports of no more than 2 m is optimal.

Training

Before drilling holes for pillars and support, the territory is placed – according to a pre-prepared plan plan. When marking the center of future holes, pegs are installed. NSLan plot or terrain takes into account the diameter of the wells – he plays the last role when choosing the optimal distance between the columns.

Square, rectangular or round – pipe must be painted on equal parts. For example, clay soil involves cutting pipes in 3.2 m (1.2 “drowning” into the ground and composed by concrete). The diameter of the well – 40-50 cm. In the process of markup, the territory should be covered around the perimeter with a fishing line or a thin beans stretched on pegs. The latter are located at the corners of the site. On this line, the same distance between the columns is measured. Staggers in the form of additional pegs.

Stages of work

To dig in the ground of the well, follow the next sequence of actions.

  1. Dut it with a shovel of a small (upper) layer of soil by 10-20 cm. So you will set the intended location of the future well.
  2. Install the borrow strictly vertically. Start with it to cut the plastic of the earth behind the plast, keeping the vertical position. Rendress a small pressure to the tool – without effort from the Master, it will not turn deep into so quickly as much as it is necessary to work effectively. Too strong pressing and unnecessarily fast Promotion of the grinding of the soil can damage the cutting edge with outsidated large-scale inclusions. The rapidly increasing resistance of the destroyed soil “will seek” engine turnover.
  3. Having done a few full revolutions, remove the drill from the ground, Removing the destroyed soil and clearing the cutting edges from the nanileous land. Repeat two previous actions.

If the drill does not cut the earth correctly and efficiently, as at the beginning of work, check if the cutting edges did not fade. Blind of blades – Frequent phenomenon on a solid ground, in which stones and other extraneous particles can come across, different from the shallow clay structure.

  1. With the help of electric or gasoline yamobur, the drilling of the soil will accelerate significantly. The sequence of drilling under the poles or piles here may be the next.
  2. Install the work part (cutting tool), fixing its shank in the clamping drive mechanism. Check if the axis did not be twisted – when rotating the curved axis “walks” in different directions, it is easy to check by finding the rhythmic deviations of the top of the borax in different directions. The displacement of the working tool will be given a bean beyon when drilling.
  3. Install the drive with a brown vertically. Start a booze.
  4. When the drill will slow down the speed of revolutions to a value at which the performance of the work sharply drops, turn on the reverse mode (reverse). This will give an opportunity to get out of the destroyed soil. Rolls will rise. Switch the motor or electrolycore from the reverse again to the usual and break the drilled layer.
  5. Remove the destroyed breed from the wells, clean the blades from the nanileous land. Continue drilling, moving further deep into.
  6. Repeat drilling until the well reaches the desired (by technical) depth.

If the buoying has become noticeably harder, and the efficiency and drilling speed decreased noticeably, pour into the well to 20-30 liters of water. Hardened and overly rammed by the supervisory layers soil softened. Since clay turns into difficult dirt, it is useful to continue drilling the same hole after a day or two – when the water is completely absorbed, and the upper layers of clay will not stick to the Bura blades.

The screw burrow, which is most often used with a motoblock or electric drive, like a drill, a rooking tree or metal, displays a significant part of the soil out on their own. After installing in the direction of drilling and with further promotion, it is not necessary to pull it up, removing the earth – only simple borants have this disadvantage, the cutting part of which is made of two halves.

Too dense ground will require the drilling of the well at low speed – the mechanized car has several speeds. Observing exactly the technology of drilling holes under the poles, the wizard will provide high quality and durability of pillars for the fence or small construction. Deviation from the above-described schemes will almost immediately lead to the hauling structures.
