The invention relates to the technical field of bridge construction monitoring, in particular to a monitoring system and method of the overall vertical rotation construction of a main tower. The monitoring system of the overall vertical rotation construction of the main tower comprises a first large floating crane ship GPS (Global Positioning System), a second large floating crane ship GPS, a maintower positioning device, a first small floating crane ship GPS and a second small floating crane ship GPS, wherein the first large floating crane ship GPS and the second large floating crane ship GPS are respectively arranged on the bow and the stern of a large floating crane ship, and the orientation slope with the large floating crane ship as a base line is calculated by obtaining the coordinates of the bow and the stern of the large floating crane ship; the main tower positioning device is arranged on an upper lifting appliance so as to obtain the coordinate of the main tower and calculate the offset distance of the main tower relative to the base line based on the orientation slope; and the first small floating crane ship GPS and the second small floating crane ship GPS are respectively arranged on the bow and the stern of a small floating crane ship so as to obtain the coordinates of the bow and the stern of the small floating crane ship, and the offset distance of the bow and the stern of the small floating crane ship relative to the base line is calculated based on the orientation slope. The problem of the collision risk because the construction instruction guidance cannotbe performed on the whole vertical rotation process in the prior art can be solved.
Description
technical field [0001] The invention relates to the technical field of bridge construction monitoring, in particular to a construction monitoring system and method for integral vertical rotation of a main tower. Background technique [0002] The steel tower is an important force transmission component of the cable-stayed bridge. Its design and construction are directly related to the safety of the entire cable-stayed bridge. The general conventional steel tower, due to its overall volume and weight, is relatively large. The overall hoisting is more difficult, and the method of segmental assembly is often used. Several segments are hoisted to the installation point in sequence, and then welded and assembled segment by segment at the installation point until a complete steel tower is formed. However, the location and environment of the bridge construction is relatively harsh, and the on-site welding and assembly work is affected by multiple factors including wind, rain, waves,...
