you need
  • - hydraulic 10-or 20-ton jack;
  • - wooden beams cross section about 150h250 mm or railway sleepers;
  • - construction and carpenter's tool (crowbar, shovel, ax, etc.);
  • - thick metal plate (lining under the head of the jack).
Calculate the approximate burden on angle home (weight home , divided by 4).This option is needed to find the dimensions of the boards, which will be based angle home after his recovery.Please note as a reference the following information: set on the edge of a railway sleeper, having a section 160h230 mm, with a length of 2.5 m span can withstand a central load of 4.5 tons.
Locate the jacking.It must be
chosen taking into account the specific situation.If you pick up the house to replace the bottom decayed crowns the new, cut an opening in the crowns of these logs to a whole, which will have to rest on the jack.The opening should be cut wide enough to make it fit the jack and bars, which will build a house after lifting.
If the house is raised to increase the height of the foundation or the cap, then, to bring the head of the jack under the beam, it is necessary to hollow niche in the basement - if the tape.If the house is located on the pier foundation, the need for gouging niche disappears.
Establish a jack under a log.If you are under its fifth ground, tamp it well and put on him a bar or a thick board.If the jack is under the surface of the concrete foundation, and put on her thick board needed to load and stability of the heel.
under the head of the jack enclose thick steel plate measuring about 10x10 cm. It is desirable to have a small concavity in the center or milling - as a guarantee against sliding head.Podteshite beam in place of backing up - in a horizontal plane.
Set next to the rail angle, sticking it in the ground.Mark the rail and coal home lines are at the same level.The mutual location of these lines during lifting will report the amount of lift.Monitor this enachenie on the nomination of the jack rod is impossible, since it would be pressed into the heel of the board and the ground.
Start rise home , working the jack handle.At the same time pay attention to it vertically.If there is a deviation from the vertical tool, stop the rise and set the jack again.
When work is guided by such pravilami.Podem home should be carried out simultaneously by two jacks mounted at corner areas home .Lift one corner possible only if he sank against the other three, and it is necessary to align it.
Raising one hand in one cycle should not exceed 4-6 cm. After that you need to put under the wall stops and begin to lift the opposite direction.
Raised side is fixed in two ways - the thick lining boards between the log and the base unit or the so-called "bench".In the latter case, the timber is enclosed by a wall perpendicular to it, and its ends rest on supports mounted on opposite sides of the wall.Choosing a particular method it should be based on the nature of work done to the house (replacement of crowns, topping up the foundation and so on.).
