Motorists asked to get a shallow pit that allows you to perform repair of machines sitting. Energy and materials it takes much less than in the arrangement of any ie “polnost governmental” counterparts. And work convenient. Is a mini-pit in two parts: a sump with a slanted end (it falls under the car) and depth, equipped with mortise seat. Wall recommend to impose with a brick. If there is roofing iron, it is quite possible to do the lining and out of it in the form of a welded box construction. Not the best option (but more affordable) is to dig a wooden stand with a subsequent interior wall boards, plywood or plastic. But the bottom (if there is no soil water) can be left in excavation without any coverage.
At the entrance and setting the vehicle on the repair end of the viewing of the mini-pit will experience a considerable burden. So they need to strengthen. First, a strong frame, cook it from a steel angle 70×70 mm and setting at the place where the walls are lined. Second, extensive pavement, filling voids under the frame and on the edges of the holes with cement mortar with aggregate — broken brick. In addition, the perimeter to attach the U-shaped structure welded from steel angle 40×40 mm, which will serve as a support removable decking boards with a minimum thickness of 40 mm.
