Pile - strip foundations with their own hands

pile-strip foundation - a kind of monolithic foundation for heaving and weak soils.Its peculiarity lies in the fact that the walls of the building are based on a solid foundation melkozaglublenny tape around the perimeter and a strong bond with the solid layers of soil is ensured by piles, buried below the depth of frost penetration.Such an arrangement allows, on one hand, to reduce the construction costs, and on the other - to provide high strength and load characteristics of the building.

Advantages pile-strip foundation

• Low price;
• performed quickly, we can pile-strip foundations with their own hands without the use of special equipment;
• can be installed in areas with any relief;
• Excellent resists heave and seasonal shifting of the soil.

Among the shortcomings can be noted the impossibility of devices full basement.

design and application of pile-strip foundations

pile-band foundation to transfer the building load on the ground with the help of two structural parts: a foundation tape mounted on the perimeter of the building and under the load-bearing partition walls, and piles, providing the foundation strength during seasonalground movements.Piles and tape reinforced foundation reinforcement.The piles can be formed as bored manner and using asbestos pipes filled with concrete.In recent years, great popularity received a metal screw piles with drilling blades on the lower end.Tape foundation performed by pouring concrete.

pile-strip foundations are used for the private low-rise building houses, cottages and other buildings with basement.They can be installed on a ground inclined to heave, and in areas with a large height difference.This foundation is much cheaper and faster than buried.

technology implementation

1. Site preparation is reduced to the clearing of debris, alignment and marking.Trench digging under the foundation tape shallow, up to half a meter.The bottom of the trench backfilled with sand or gravel providing water drainage from the base and reduces the swelling of adjacent soil layers.In the corners, at the intersection of load-bearing structures, as well as on the perimeter walls of about 2 meters brown perform well under the pile.Well depth - 0.3-0.5 m greater than the depth of freezing ground.The diameter of the holes is selected so that the piles were freely into the well.

2. The well is filled river sand, forming a thick cushion of 15-20 cm. Sand shed water and ram.Once installed asbestos or metal pipe, pour concrete of 30-40 cm and lift them by 20 cm. Concrete, flowing into the space under the pile, forming extension so-called sole.It provides better adherence piles with solid soil layers.While the concrete is grasped, aligned upright supports on a level.After hardening of concrete pipes inserted into the reinforcing cage made of several metal rods, and forming a wired lattice.The height of the reinforcement must be such that it is exposed from the pipe and reaches almost to the top of the basement tapes.

3. above the ground performing a wooden formwork required height.Collect the formwork by means of nails or screws, reinforcing bars at the corners.All speakers have a structure from the outside formwork.Walls strengthen ties and braces.Inside the valve casing lay: rod diameter of 8-16 cm, depending on the computational load placed in all three directions, forming a three-dimensional grid.At the intersections of the bars-wire with a hook for tying rebar.Be sure to connect the reinforcement of the foundation piles and tape - this compound provides structural strength.

4. first poured concrete piles, and then the whole foundation of the tape.Be sure to remove the remaining air from the structure using vibrators or conventional rebar, piercing the thick solution in multiple locations at each site of the foundation.Mirror foundation even and smooth, and the rule is isolated from the precipitation covering materials or plastic wrap.In the process of drying the basement check its moisture and prevent drying out, this too hot weather, it should be slightly moistened.

5. After pour concrete and set them with the necessary strength can start to insulation and waterproofing of the foundation.Concrete - hygroscopic and thermally conductive material.The wet concrete during freezing crack, which leads to the destruction of the foundation.Therefore, it is recommended immediately after the construction of the foundation to fulfill its waterproofing.Usually used for this purpose, or bituminous polymeric mastic or roll materials: self-adhesive membrane roofing material or film.The concrete surface must be primed before waterproofing with a special solution, and antisepikom.After drying, the walls covered with primer waterproofing.

6. Warming foundation of the house - an important step to creating a warm and stable climate.The use of modern materials and techniques will raise the temperature in the basement space to above zero even in the midst of frost.The most popular methods are thermal insulation insulation using polystyrene or polyurethane foam.Polystyrene - a new modification of the well-known foam, resistant to mechanical stress and provides good insulation.Plates glue to a special glue, and after drying additionally secured with dowels.

7. Polyurethane foam - sprayed coatings, similar in principle to the mounting foam, but its thermal insulation properties are much higher.For its application requires special installation.
