face application In order to ensure the smooth construction of the bridge, we should organize technical personnel to tackle key problems and apply many new technologies. In view of the difficulties in the construction of large diameter and ultra long bored piles in water, a special plan for the drilling pile of the main pier is worked out. It is reasonable to organize, guide the construction through the fine management of the construction through the underwater generous concrete, and combine the professional equipment, use the high quality PHP mud, speed up the pile forming speed, reduce the disturbance, and strengthen the capacity of the mud wall to ensure the bored pile coagulation. Continuous filling of soil ensures the quality of pile forming. In the construction of the tower cantilever, the technicians monitor the stress and partial position of the tower through the control section of the tower, and establish the finite element analysis model of the construction process of the tower, calculate the force state of the control section of the tower, and clear the position of the active transverse bracing of the tower column, so as to change the bad stress on the lateral of the root of the tower. Force state. In the construction of cable anchorage area, through the simulation of the relative position of the buried steel plate and the cable conduit in the anchorage area, the ground is accurately assembled and hoisting, and the indirect positioning method is used to locate the cable conduit by measuring the pre buried plate, so that the cable catheter is fixed firmly by the stiffening skeleton to avoid the displacement in the pouring.
the manager set up the idea of safety first firmly in the process of construction, cling to the safety and quality, persisting in carrying out a number of measures to ensure the safety of the safety quality and ensuring the safety and controllability of the construction of the bridge. In the construction organization, special safety construction plans are worked out for all kinds of cross construction operations to ensure the smooth construction of the main bridge. In the construction of the beam on the tower, the safety special basis of the beam construction is organized, the stable operating platform is set up and the dark anti dizziness safety net is suspended, so as to ensure the safety of the operation personnel, and pass through the construction safety. Safety training and education for construction teams should be improved, and the level of "know what should be" and emergency rescue skills should be improved. At the same time, we should insist on "leading the class", carry on the on-the-spot work of the key construction process, ensure the safe and orderly conduct of the site construction, strictly implement the on-site inspection of the duty department, and make a thorough investigation on the "three violations" of the scene, that is, the illegal operation, the violation of the command, the violation of the labor discipline, and the hidden dangers. Over the night. Thanks to the attention to the risk awareness of the safety quality, no major safety accidents have occurred since the construction of the the Yellow River highway bridge in Ji Qi, which ensures the smooth construction. The management department of
focuses on the research and development of bridge technology. In order to train a batch of modern bridge technical personnel to promote bridge technical innovation, the technical innovation of steel mixed composite beam bridge is realized. On the optimization of construction technology and programs, we have come up with a batch of high-quality scientific and technological innovation achievements. The multi function inverted trapezium brackets of "large span cable tower bottom beam landing slanted leg", "super high cable tower and large span beam composite hoist steel truss support", "vertical bar integral hoisting hoist", "steel beam starting section", top lift sliding combination type "multifunction inverted trapezoid support" and "construction method", "steel anchor beam built in cable tower" Many technical problems, such as "through sling" and other technical problems, and obtained national patents. At present, the QC team of the Ministry of management has completed 7 national patents and 2 engineering methods. In July 2016, the project department won the first prize in the national quality management.
