1). the existing building that increases layer in plan carries out the construction of foundation ditch retaining structure on every side, and retaining structure adopts a placing of reinforcement concrete drilling bored concrete pile and row's rotary churning pile to form;
2). begin to excavate foundation soil from indoor terrace, until former single footing end face;
3). the end face vertical drilling in former single footing is pressed into prefabricated steel drum concrete pile in the ground to projected depth the little cushion cap of cast steel drum concrete pile on the end face of former single footing by vertical drilling place, former single footing;
4). set the well-points dewatering pipe in foundation ditch retaining structure inboard, carry out precipitation;
5). continue the earthwork below excavation side, former single footing and the bottom surface, the absolute altitude place, base plate bottom surface that excavation is most planned to build basement makes the single footing reveal; Former single footing is supported by the steel drum concrete pile;
6). the excavation substrate is floating with concrete, and end face tiltedly bores injected hole in former single footing, the frame column on the former single footing is prolonged be poured into the end, hole, form the frame column that prolongs, and bottom board forms new basis;
7). outer unnecessary former single footing of the frame column that amputation prolongs and the steel drum concrete pile on the new single footing;
8). the top layer reinforcement of former frame column;
9). the basement roof cast;
10). external wall construction around the newly-built basement.
Beneficial effect: after the construction of this worker method was accomplished, the superstructure load was delivered to basement bottom board through the frame column that prolongs, and is born jointly by foundation soil under the base plate and steel drum concrete pile.Basement increases layer secondary deformation that construction causes and can be effectively controlled, and has reduced the original building effect on structure, and construction period does not influence the normal use of two layers of original structures and above floor.
