Abstract

Abstract A building raising and underpinning system wherein plates or brackets are attached to the building walls or foundation spaced generally equidistant about the perimeter of the building and hydraulic rams are operatively engaged with the wall plates to drive a plurality piles into supporting ground simultaneously. The hydraulic rams are controlled first not to exceed pressures that would develop forces that would raise the building until all of the piles attain a point of stability in the supporting ground and thereby provide uniform support at all of the piles for subsequent raising of the building under pressures then developed simultaneously in the hydraulic rams to provide the force represented by the total weight of the building structure which may be supplemented by temporarily added weight, is utilized for the initial driving of the piles by the hydraulic rams. Hydraulic power apparatus and controls are provided which require minimum labor and which incorporates equipment to perform all of the functions of driving the piles without raising the building and then simultaneously actuate all of the hydraulic rams to raise the building uniformly.
