L68B1 Mast SectionImproper, unreasonable, upside down and upside down construction sequence will lead to tower crane accidents

20-11-2019

Tower Crane accidents have been greatly reduced, but they still occur. It is found that there are many reasons such as design, production, installation and use when analyzing the causes of construction quality problems. Some of them are caused by improper construction sequence arrangement, unreasonable overlap of working procedure, even inversion and reversal of working procedure, blindly seeking more and faster and not leaving the necessary technical interval of tower crane. In this paper, how to reasonably arrange the construction sequence to avoid the tower crane accident. 1. The foundation rock drilling is a mere formality, some symbolic drilling holes, and then random compilation of rock drilling records, can not truly reflect the underground obstacles, holes and the actual bearing capacity of the foundation. 2. Terrazzo windowsills or other plates should be installed at the same time as the inner wall is plastered with mortar. If they are installed again after plastering, they need to be gouged again, which may easily lead to the hollow of the Outer Wall windowsills Sun Angle and window sill plate heating trough at the lower part of the plaster joint croucher quality is not guaranteed.

3. Pipes, boxes, etc. shall be installed by bricklayer or plasterer with electrician according to design elevation before plastering a large area of inner wall surface. At present, some construction teams start to plastering when the installation of the pipeline and the wire box is not stable. After plastering, the plastering workers will pick out the plaster and then repair the plaster. This will not only waste the manpower and materials, but also make the plaster hollow and crack easily. 4, bathroom, kitchen paste glazed tile order is wrong. The electrician and the bricklayer should cooperate together to install the switch box and socket box to the predetermined position in the process of installing the glazed tiles. While some projects are under construction, bricklayers and electricians take care of each other.
