The utility model discloses a UHPC (Ultra High Performance Concrete)-steel bar reinforced pier cover beam structure, which belongs to the technical field of bridge reinforcement and comprises a plurality of transverse embedded steel bars positioned on two side surfaces of an original cover beam and arranged at intervals along the transverse direction of the original cover beam; the longitudinal embedded steel bars are located on the two end faces of the original bent cap and arranged at intervals in the longitudinal direction of the original bent cap. The transverse stress main ribs are arranged on the upper side of the original bent cap at intervals in the longitudinal direction of the original bent cap. The multiple inverted-U-shaped stirrups are arranged at intervals in the transverse direction of the original bent cap. The longitudinal embedded steel bars, the transverse embedded steel bars, the inverted-U-shaped stirrups and the transverse stress main steel bars are all connected with a main body framework of an original bent cap to form a widened part of the original bent cap. And the UHPC concrete layer is poured on the widened part of the original bent cap. As the sectional dimension of the pier capping beam is increased, the problem that the capping beam cannot meet the requirement of a new anti-seismic specification on the minimum distance from the beam end to the edge of the capping beam is solved.

Construction method of deep and large foundation pit without support replacement
ActiveCN116104104BReduce construction proceduresreduce construction costsHydro energy generationExcavationsArchitectural engineeringEconomic benefits
This invention discloses a construction method for deep and large foundation pits without the need for replacement supports, belonging to the field of underground structure sequential construction technology. During the main structure construction, after the previous formwork sidewall is completed, only the next steel support is removed; replacement supports are no longer installed, thus eliminating the need for replacement supports. Only the concrete supports are cut, retaining the lintel beams, which function as part of the sidewall, allowing them to play a role in both the excavation and main structure construction phases. The bottom slab ribs are adjusted from triangular bevels to stepped shapes, allowing the scaffold uprights to act vertically on the ribs, ensuring the overall stability of the scaffold. The increased rib cross-sectional dimensions reduce the impact of lateral deformation of the foundation pit on the sidewalls. This invention shortens the construction process, reduces construction costs, ensures foundation pit safety, and has good economic benefits.
