Abstract

The invention provides a settlement monitoring method for hanging basket construction. The settlement monitoring method comprises the following steps: processing multiple tubular fiber grating monitoring pieces, wherein each tubular fiber grating monitoring piece is provided with multiple fiber gratings connected with an interrogator; after construction of multiple piers is completed, determining the number of the tubular fiber grating monitoring pieces between every two adjacent piers according to a distance between the two piers; constructing a reference bridge blocks on each pier, constructing a connection bridge block from each reference bridge block serving as a start point towards two sides of the reference bridge block, and forming a bridge by the multiple connection bridge blocks located on the same sides of the piers; during construction of the connection bridge blocks, mounting the tubular fiber grating monitoring pieces in sequence along the construction direction of the connection bridge blocks to monitor settlement of each bridge till the connection bridge blocks on every two adjacent piers are closed; during construction of the connection bridge blocks symmetric about the piers, analyzing reasons in time according to a settlement value omega1 of the bridge on one side of each pier and a settlement value omega2 of the bridge on the other side, then adjusting the settlement, and constructing the connection bridge blocks symmetric about the pier. According to the settlement monitoring method for hanging basket construction, the problem that the settlement during the hanging basket construction cannot be monitored in real time is solved.

Description

technical field [0001] The invention relates to the field of engineering construction, in particular to a settlement monitoring method for hanging basket construction. Background technique [0002] Hanging basket construction refers to the segmental cantilever operation using the hanging basket method when pouring concrete continuous long-span cantilever beam bridges. In the suspension grouting construction, the reference bridge blocks are poured first, and the formwork is removed after the concrete reaches the design strength, the longitudinal, horizontal and vertical prestressed steel bars are stretched, anchored, and grouted; the hanging basket is vertically symmetrical and balanced and cantilevered section by section until the closing section. It requires neither erecting stands nor the use of large spreaders. Compared with other methods, its construction method has the advantages of simple and convenient assembly and light structure. However, the main girder elevation...
