Launching beam monitoring control construction method

Abstract

The invention relates to the technical field of bridge incremental launching construction, and especially relates to a launching beam monitoring control construction method. The method comprises the following steps: 1, determining the position where a concrete stressometer sensor is buried; 2, embedding a concrete stressometer sensor in a beam body of the launching beam, connecting the concrete stressometer sensor with one end of a first cable, and enabling the other end of the first cable to extend out of a template; 3, pouring concrete into the template to form the launching beam; 4, connecting the first cable with an acquisition device; 5, mounting a sticking type stressometer sensor on the outer surface of the launching beam and connecting the sticking type stressometer sensor with theacquisition device; and 6, connecting the acquisition device with a reading device, and monitoring the acquired data in real time. Due to the fact that the concrete stressometer sensor and the sticking type stressometer sensor are installed, the stress values of the inner surface and the outer surface of the launching beam are monitored in real time, the launching beam is prevented from crackingin the prefabricating and launching process, and the construction quality and safety are guaranteed.

Description

technical field [0001] The invention relates to the technical field of bridge jacking construction, in particular to a construction method for monitoring and controlling a jacking beam. Background technique [0002] In the concrete beam jacking construction, the beam body often cracks due to the excessive internal stress of the beam body during prefabrication and jacking. The traditional control method is based on the specifications and the experience of technicians and construction personnel. , but the range of man-made control is limited, not precise and fine enough, which will affect the structure of the push beam and cause inconvenience to the construction. Contents of the invention [0003] The purpose of the present invention is to: in view of the prior art, when prefabricated and pushed, the beam body often cracks due to the excessive internal stress of the beam body when the push beam is prefabricated and pushed. To solve the problem of limited scope, insufficient...
