Abstract

The invention provides a settlement monitoring method for cantilever casting construction. The settlement monitoring method comprises the following steps: machining a plurality of fiber grating monitoring members, wherein each fiber grating monitoring member is respectively provided with a fiber grating banking indicator connected with a demodulation instrument; after the construction of a plurality of bridge piers is completed, constructing a number-0 bridge beam block on the top surface of each bridge pier, constructing connecting bridge blocks on two sides of the number-0 bridge block serving as a starting point, wherein a plurality of connecting bridge blocks located on the same side of the bridge pier form a bridge; when the connecting bridge block is constructed, successively installing the fiber grating monitoring members along the construction direction of the connecting bridge block by adopting the number-0 bridge block as the starting point so as to monitor a settlement valueof the bridge until the connecting bridge blocks on two adjacent bridge piers are in butt joint with each other; and when the connecting bridge blocks symmetric about the pier are constructed, analyzing the reason according to the settlement value of the bridge at one side of the bridge pier and the settlement value of the bridge on the other side, adjusting, and then performing the construction.By adopting the settlement monitoring method, the problem in the prior art when in cantilever casting construction, the real-time monitoring cannot be performed can be solved.

Description

technical field [0001] The invention relates to the technical field of engineering construction, in particular to a settlement monitoring method for suspended irrigation construction. Background technique [0002] Suspension grouting construction has been widely used in bridge construction. However, there are many safety hazards in the construction process, and engineering problems arising from the uneven settlement of the bridge during the suspension irrigation construction process emerge in endlessly. The existing intelligent monitoring method is mainly to monitor the settlement of the bridge during operation, and the traditional monitoring method is still mainly used in the suspension grouting construction process. The existing suspended irrigation construction is mainly to study its construction technology, and the traditional level and total station are used for monitoring. There are unfavorable factors such as discontinuous monitoring and large human errors. Content...
