You will need

– hydraulic 10-minute or 20-ton Jack;
– wooden beams cross-section about 150х250 mm or railroad ties;
construction and carpentry tools (crowbar, shovel, axe, etc.);
– thick metallic plate (lining under the head of the Jack).

Instruction

Calculate the approximate load on the corner of the house (the weight of the house, divided by 4). This parameter is necessary in order to choose the size of the beams, which will draw the corner of the house after his recovery. Please note as reference the following information: installed at the edge of the railroad tie, having a section 160х230 mm, with a span length of 2.5 m can withstand a Central load is 4.5 tons.

Determine the location of the focus of Jack. It should be chosen according to the specific situation. If you raise a house to replace the rotten bottom of the new crowns, cut an opening in these crowns until the whole log, which will rest on the Jack. The opening should be cut wide enough to fit the Jack and the beams, which will build the house after lifting.

If the house is raised to increase the height of the Foundation or base, then, to bring the head of the Jack under the beam, it is necessary to hollow out a niche in the Foundation – if it is the belt. If the house is located on the pier Foundation, the need for the excavation of the niche disappears.

Place a Jack under the log. If its fifth is the soil, tamp it well and put it on a Board or thick Board. If Jack is the concrete surface of the Foundation, also put it on a thick Board that is necessary for load distribution and stability of the heel.

Under the head of the Jack put a thick steel plate with a size of about 10 × 10 cm, it is Desirable to have in the centre a small concavity or milling – in as a guarantee against slipping off of the head. Podesite the beam in the place of installation of the lining in a horizontal plane.

Set near the corner of the rail, sticking it into the ground. Mark, on the rail and on the corner of the house line, which is on the same level. The alignment of these lines during the lifting process, will report on the amount of lift. To control this Anakena the extension of the rod of the Jack is impossible, because his heel will be pressed into the Board and the ground.

Start lifting at home, working the Jack handle. At the same time, pay attention to its verticality. If there is a deviation of the instrument from the vertical, stop the lift and set the Jack again.

When working, follow these rules.The rise of the house should be carried out simultaneously by two jacks, mounted under the corner of the house. Lifting one corner only if he slipped to the three others and have to align it.

Lifting one hand in a single cycle should not exceed 4-6 cm then you need to put under the wall stops and start to lift the opposite side.

Raised face fixed in two ways – padded thick boards between the beam and the Foundation or device of the so-called "benches." In the latter case the timber is placed under the wall perpendicular to it, and its ends rest on bearings mounted on opposite sides of the wall. To choose a particular method should be based on the nature of the work produced by the house (replacement of crowns, filling of Foundation, etc.).
