Concreting pillars for fence - operation with the " pitfalls "

concreting Why do we support?

Do not think that the use of concrete in building fences so monotonous.In fact, in addition to the most popular spot concreting, there are several methods that provide a reliable basis for the fence:

• Dry concreting - in a well mounted supporting a fence post, and then filled up with a mixture of gravel and sand and watered copiously with water.The disadvantage of this method - the fence can become loose due to heavy loads.
• Strip foundation - the surest way, but also the most expensive and time-consuming.

Concreting has advantages:

• durability;
• corrosion protection;
• support not falter in the ground.

downside concrete base of the column is its bulging out of the ground in the spring, when the snow melts.This occurs if the ground water are close to the earth's surface, during melting their level rises, pushing construction upstairs.Post out with concrete, which then burst.

Site preparation

to produce concreting fence poles, it is necessary to prepare the garden and the earth auger, bubble level, bayonet shovel, drill, concrete, wooden beams, rebar, roofing felt, plastic bags.

First prepare the surface.To do this, the desired location of acute bayonet shovel is necessary to clean the roots and cut turf.It is imperative that they do not interfere with future drilling.hole size depends on the diameter of the drill.The deepening of the garden set the drill.Go through it should be possible to deeply.Soil that has been extracted, it is better to ship in wheelbarrow and removed in a prepared place.If the garden of the drill is not enough, we must apply the ground.

Earth need to be drilled to a depth of soil freezing, that is 1.7 m. After completion it is necessary to set the extender to the plow.This is followed by making the anchor extension at the bottom of the pit.This will enable the post in the cold not be pushed out, and remain in the same place.

now isolated from groundwater concrete itself.This can make the tube of roofing material and put on a plastic bag at its end.This construction should be inserted into the hole and start concreting.To the tube does not spin, it is necessary to build a low box-timbering of scrap boards and set above the ground.

carry out concreting pillars correctly

During pouring the solution is to press the tube of roofing material to the walls of the well, so that accumulated at the bottom of the water will be displaced upward.Concrete will be fully protected from water and soil by means of folds straightened polyethylene bag.As the funnel, you can use an old bottomless bucket.In addition, the need to constantly shtykovat rail concrete.

Before reaching the top of the hole, it is necessary to stop the flooding of the solution.In the just-filled solution is necessary to insert reinforcing rods.Their length shall be lower than the finished column.In order to limit the height of the pillars should pull the cord along the fence line.Next you need to vymeryat distance from the cord to the wooden box, which is mounted in the center of the hole.Now the distance is marked on the pipe made of asbestos, and the starting point will be considered as its tip.

then drilled in the pipe through-hole into which the pin is placed from a steel rod, and the tube is put on the valve, which looks out from a hole in the ground.Pin will keep the tube in a suspended form, based on box-timbering.

next step is to align the columns vertically.To do this, you need to fix the bubble level to the tops of the tubes.Securing their braces, concreting keep the top of the well.At the end of filling the wells with a solution you want to remove a steel pin.A tube which has been established, it remains for the setting of concrete a day.
