Reliable and durable strip foundations on stilts

Foundation is the foundation of any structure, accordingly, it must be reliable and durable, so it has a huge popularity strip foundations on stilts.

reliability of the base due to the fact that the walls of buildings are based on monolithic melkozaglublenny strip foundation and piles are located below the level of soil freezing, provides strong adhesion to solid soil layers.

often even replacing the old foundation is in the pile foundation type.

However, the replacement of the foundation will strengthen the structure only when properly executed works.

Advantages and disadvantages

The advantages of pile-belt base include:

• the possibility of building on the low marshy ground and on a plot with a slope;
• low cost;
• use a small amount of building materials;
• ability to perform all the works of their hands;
• rapid construction of the foundation without the involvement of specialized equipment;
• great opposition movement of the soil.

Despite the weighty dignity, pile-strip foundation still has shortcomings, which include: the inability to use the piles of heavy large buildings, the inability of the basement and ground floor unit, required complex calculation base.

A correct calculation is the key to the long life of the entire structure.

But despite the drawbacks, this type of base is widespread in today's construction world and is perfect for the construction of baths, arbors, low houses and small cottages.

Types pile-strip foundation

pile-strip foundation is divided into certain types, different types of piles installed, which can be screw or bored.

Screw piles look like very large screws, which are screwed into the ground.Performs screw piles of steel pipe with the blades of the screw thread.

This thread provides increased contact area and rigidity of fastening in the soil.Screw piles are possible with your hands, or resort to the help of special equipment.

piles Dimensions are as follows: diameter - 50-130 mm, length - 1600-3500 mm.

important point in the installation of screw piles is mandatory painting elements that will provide long term service life of piles.

As advantage of screw piles can be noted that their replacement is simpler than other types of piles made if necessary.

Yet replacement - a very complex process and is not always all work can be done by hand.
for devices bored piles need to drill holes.

installation technology of piles depends on the type of soil.If the soil is hard and not showered, the concrete can be poured directly into the drilled hole.

And if the foundation is being built in an unstable or wet ground, you need to make cased.

for casing pipe will need: cardboard, steel or asbestos cement, which will serve as an additional waterproofing.The tube must be inserted into a drilled hole and fill with cement mortar.

Bored piles are better suited for the construction of the foundation with his own hands.

pile-tape base may be melkozaglublennym or not flush at all.

Melkozaglublenny foundation is used for buildings of wood-based materials, buildings with two or more floors.

not flush the foundation - for the construction of baths and other small structures.

Tech Gadgets If you work with your hands, it is better to choose to install the round shape of the pile.For rectangular bearings require special equipment, the use of which increases the financial costs.

Perform all steps can be clearly seen in a video.

first calculates the size of the foundation.The calculation is based on the analysis of soil characteristics.

calculation should be made taking into account the wind load on the structure, size and mass of materials slope.it is important to correctly determine the number of piles for the construction of reliability.

independently make calculations difficult, so it is best to turn to professionals.

should be borne in mind that if replacing piles, make sure the new calculations have to be made.

After determining the calculated indices performed markup.Further, according to the markup, you need to dig a trench depth of 40 cm

Video:.

width of the trench is determined individually for each project, depending on the area of ​​the basement, and why are calculated.

The next step is to drill holes for piles on the corners and perimeter trench.The pits should be located at a distance of 2 m from each other.

drilling depth should be greater than the level of soil freezing by 50 cm. That depth will be enough for a sand cushion device.

diameter hole is 1/3 of the width of the tape of the trench.

When wells are ready, you can proceed to the installation of waterproofing material.To do this, all the wells is necessary to lay roofing material.

Now we need to make base tape.The first is filled pillow of sand or gravel layer 30 cm, which will provide water drainage from the foundation.

Next set of shuttering boards.They are fastened together with nails or screws.

Next you need to make the reinforcement bars with diameter of 12 mm.They need each other to seal the special wire to increase the strength of the foundation.

reinforcing tape is not only the foundation, but also for all the piles installed reinforcing belt.

reinforcement When finished, you can start pouring the foundation.First grout filled wells.

When filling tape base every 20 cm filled cement mixture you need to level to eliminate voids.

poured concrete formwork to the full height.Pour the tape base and the pile should be at minimum intervals.

If selected bored the way the first set of the pipe, and then filled with concrete.

First you need to pour 40 cm of the solution, and then lift the tube to mix concrete fell under the pile, forming a so-called sole.This design provides good traction with the ground.

Before hardening solution to align the level of the pile.

After solidification of the solution in the pipe to be inserted reinforcing cage, consisting of steel rods connected by a wire, forming a lattice.

reinforcement cage should extend from the pipe to the top of the base tape.

Three days later, the formwork can be removed and do waterproofing tape base with roofing material.

In general, the device of pile-strip foundation with his own hands is not difficult, the main thing - that all the work carried out with the maximum care and responsibility, otherwise the base will be short-lived and may soon need to be replaced piles.
