Unbalanced weight monitoring device and construction method for overall process of construction of hanging basket at upper part of horizontal rotation T structure

Abstract

Aiming at the defects of the existing bridge rotation construction monitoring method, the invention provides an unbalanced weight stress monitoring device and method for the overall process of construction of a hanging basket at the upper part of a horizontal rotation T structure. The monitoring device provided by the invention comprises outer sleeves of sand boxes, inner sleeves of the sand boxes, middle dry sand of the sand boxes and pressure boxes. The monitoring device is simple in structure, low in sand box cost and simple in manufacturing process. The monitoring device is simple in construction method, firm and stable in structure and easy to disassemble and clear after being used, and the cost of manpower and material resources can be saved. According to the invention, data can be read conveniently and reliably, thereby effectively ensuring the structure process safety.

Description

technical field [0001] The invention belongs to the technical field of bridge swivel construction monitoring, and in particular relates to an unbalanced weight monitoring device and a construction method used in the whole construction process of a hanging basket on the upper part of a horizontally swivel T structure. Background technique [0002] During the whole process of the construction of the upper T structure hanging basket of the bridge, the swivel T structure is different from the ordinary T structure. During the construction of the upper structure, the pier bottom and the cap are temporarily consolidated. To be able to be evenly compressed during construction, the control of the center of gravity of the T-structure and the weight balance control on both sides of the T-structure are even more critical. [0003] The current monitoring method is mainly to embed concrete strain gauges under the spherical hinge in the lower turntable, the bottom of the pier and the concr...

Problems solved by technology

This will not only greatly increase the monitoring cost and the workload of data collection, but the key point is that sometimes the effect is minimal, because adding measuring points can only reduce the impact of concrete discreteness, but it cannot fundamentally avoid concrete creep and shrinkage, environmental temperature and the detection error caused by the season and time of the test

[0004] To sum up, the traditional monitoring method brings inevitable monitoring errors due to its own defects, which brings uncertainties to the important link of monitoring the unbalanced weight of the T-structure hanging basket construction of the swivel bridge, which affects the ball. hinge structure system safety
