Description

Coastal history block repair construction stabilizing device Technical Field The application relates to the technical field of ancient building repair construction, in particular to a coastal historical block repair construction stabilizing device. Background The riding building is a building form of a modern business with a very special feature in coastal areas in south China, and is honored as a building activated stone of a Chinese and Western combination. The typical structural feature is that the bottom layer of the building retreats along the street surface, a continuous public pedestrian passageway is reserved, and two or more floors are overhanging and covered above the passageway. The ground pavement of the riding channel usually adopts terrazzo, mosaic, red-order brick (large-order brick) or granite strip stone and other materials, and the pavement is not only a traffic carrier, but also an important component of the riding history and the landscape, and has extremely high cultural relic protection value. Through century wind and rain erosion, many building blocks face serious structural aging problems, and the problems are mainly manifested by corrosion of bearing member steel bars, loose concrete carbonization, loose beam column joints and the like. In order to prevent the original aged upright post from brittle failure or collapse under the load action during emergency reinforcement or repair construction, a temporary support system is usually required. The core process of the system is that the jacking device actively bears the load of the upper beam plate, so that the unloading of the original upright post is realized, and a safety space is provided for the subsequent replacement and reinforcement operation. However, the existing riding support and jacking technology has significant technical bottlenecks and contradictions in practical application: First, local asynchronous jacking presents a very high structural safety risk. The integrity of the riding structure is poor, if single-point or asynchronous jacking is adopted, the internal stress of the structure is rapidly redistributed. When the jacking amount exceeds the elastic deformation range (usually only a few millimeters) of the beam body, excessive secondary internal force is easily generated in adjacent unsupported areas, so that the beam body is cracked and the joints are sheared and damaged. Especially, under the condition that the building structure is extremely fragile or constructors operate improperly (such as excessive lifting), the small displacement difference can cause continuous collapse accidents. Although manual fine adjustment attempts to control risks, high consistency of multi-point jacking is difficult to ensure, the requirement of precision protection cannot be met, and the high-precision synchronous jacking technology is high in application cost and difficult to implement. In order to eliminate stress concentration caused by asynchronization, a hydraulic synchronous lifting system controlled by a computer is introduced in the engineering world, and the whole translation of the beam frame is realized by controlling all jacks to lift at the same speed (such as 1 mm/min). However, such equipment has extremely high purchase and lease costs, is complicated to operate, has an excessive economic burden for a large number of scattered and small-scale riding maintenance projects, and is difficult to popularize. Finally, the existing support foundation construction and cultural relic protection requirements have serious conflicts. Whether a traditional support or a synchronous jacking system is adopted, a stable foundation is required to be arranged on the ground of the channel so as to bear huge counter force. Conventional practice often requires digging up the original terrazzo, mosaic or red-order brick pavement to cast a concrete foundation or embed ground anchors. The destructive construction method directly damages the ground landscape with the most historic characteristics of riding, and violates the core principles of 'minimum intervention' and 'original authenticity protection' in cultural relic repair.
