Jinchuan kilometer deep well project of Zhongdu company

The natural conditions in this area are very bad, and the rock pressure is high. Many wells have been repaired for many times due to the excessive rock stress. Recently, with the deepening of shaft excavation, the construction lifting time becomes longer, which also has a certain impact on shortening the construction period. In view of all kinds of unfavorable factors, the company takes laosai as the driving force to speed up the project. On the one hand, we carried out the competition activities in engineering and technical personnel, collected a variety of construction technology improvement schemes to deal with the formation stress, and adopted the integral metal formwork support, double-layer reinforcement support and other technology to strengthen the shaft masonry, effectively overcome the potential safety hazard of rock stress release, and create conditions for safe and rapid excavation and masonry. At the same time, the company takes teams and groups as the unit to carry out the competition of winning teams and groups in the protection and maintenance of construction equipment, which fully mobilizes the enthusiasm of the staff in the maintenance of equipment in the sand blowing weather. The staff have taken measures such as setting up sheds for the equipment to prevent sand, cleaning and scrubbing the operating equipment in each shift, etc., to ensure the normal and efficient operation of the main construction equipment in the harsh natural conditions. On the other hand, the company takes the construction period as the goal, decomposes the time of each process and implements the assessment of each shift. At the same time, it carries out the competition to improve the efficiency of the operation team, and shortens the promotion time as much as possible through the labor competition activities. For individual employees, the bonus is distributed according to the work efficiency and the ability to solve problems, so as to maintain the efficient operation of each process link. (27 April 2007)
