Embodiment Construction
[0086] Such as figure 1 As shown, the implementation steps of the automatic weighing method for the swivel continuous beam used in the construction of the horizontal rotation method in this embodiment include:
[0087] 1) Starting from the random or designated start side of the continuous beam of the swivel body as the initial side, the continuous beam of the swivel body is lifted on one side by jacking on both sides of the continuous beam of the swivel body in turn with gradually increasing jacking force from the initial side, so that The jacking force of the jack is maintained within the stable range of the jacking force data for a specified time and once the jacking force steps out of the stable range, the jack will be locked, and the jacking force value of the jack in the stable range of the jacking force data is obtained as the stable value of the jacking force P 1 ;
[0088] 2) Slowly release the pressure on the jack that is applying the jacking force until the jacking ...

The invention discloses a rotation continuous beam automatic weighing method and system used for horizontal rotation construction. The rotation continuous beam automatic weighing method used for horizontal rotation construction comprises the steps of using a designated starting side as an initial side to start to alternately jack a rotation continuous beam on a single side in a side-changed mannerby using a gradually increased jacking force so as to obtain a jacking force stable value P1; continuing to slowly release pressure of the jack for applying the jacking force till the pressure of thejack is completely released; determining an attitude type of the rotation continuous beam according to displacement data in the releasing process, wherein the first type of attitude is using a reverse side of the starting side as the initial side to start to alternately jack the rotation continuous beam on a single side in a side-changed manner by using the gradually increased jacking force so asto obtain a jacking force stable value P2, and in the type of attitude, calculating the jacking force stable value P2 according to data in the full releasing process; and finally, calculating weighing data according to the the attitude type of the rotation continuous beam, the jacking force stable value P1 and the jacking force stable value P2. The rotation continuous beam automatic weighing method and system used for horizontal rotation construction has the advantages of high response speed, high executing efficiency, high automation level and convenient construction.
Description
technical field [0001] The invention relates to the construction technology of a swivel continuous beam by a horizontal rotation method, in particular to an automatic weighing method and system for a rotary continuous beam used in the horizontal rotation method construction. Background technique [0002] During the construction process of the continuous beam with the horizontal rotation method, measuring the eccentricity and friction coefficient of the structure by weighing before the rotation, and accurately adjusting the attitude of the beam body after the rotation are important processes to ensure that the beam body can rotate safely and smoothly, and accurately close the dragon. At present, the weighing and fine adjustment processes are all completed by manual operation, which has the disadvantages of poor precision control and low work efficiency. Contents of the invention [0003] The technical problem to be solved by the present invention: aiming at the above-mentio...
