Active supporting structure capable of compensating compression settling and method of active supporting structure

Abstract

The invention discloses an active supporting structure capable of compensating compression settling and a method of the active supporting structure. Wedge-shaped adjusting blocks, sand barrel, bent cap bearing beams, steel pipe columns and other structures are arranged below a bent cap cantilever to support the bent cap cantilever, a jack is adopted for supporting the cantilever, adjustment can becarried out according to the pressure bearing state of the cantilever, and the stability of a whole bent cap is improved. A connecting frame, steel frames, back steel and other structures are designed to fix the steel pipe columns, so that the supporting structure is more stable and reliable. The active supporting structure comprises a bent cap, the steel frames are mounted on the outer side of apier stud of the bent cap, and first pull rods penetrate into the steel frames. The two ends of each first pull rod are locked through nuts, and a connecting frame is mounted at the right ends of thesteel frames through bolts. The connecting frame comprises first steel channels, angle steel and connecting plates. The surfaces of the first steel channels are fixedly connected with the angle steel, and the two ends of the first steel channels are fixedly connected with the connecting plates. The back steel is mounted at the right end of the connecting frame through bolts.

Description

technical field [0001] The invention relates to an active support structure capable of compensating compression settlement, in particular to an active support structure capable of compensating compression settlement and a method thereof. Background technique [0002] In road and bridge construction projects, the prefabricated assembly technology of segmental beams is gradually adopted, and the design of cover beams adopts large cantilever structures. The large cantilever structure can make the bearing surface wider, accommodate more lanes of vehicles, and relieve traffic pressure. [0003] However, there are certain difficulties in the construction of such a large cantilever. Because the large cantilever is long, the bridge erecting machine follows from left to right when it is working, resulting in a large pressure difference between the large cantilevers on both sides, resulting in the instability of the entire cover beam structure. Therefore, how to temporarily support ...
