Beidianzi Sluice Safety Identification Technology Research And Application

Sluice in BeiDianziisan important water intake in Jinan.t As the reservoir of Yellow River water inlet for YuQing Lake, this sluice is the essential infrastructure to guarantee the development of Jinan. However, it is hardly for the sluice to make the positive effects in the development of industrial and mining establishments in rural and urban areas due to some seepage path problems.. Safely running of sluice is directly related to national economic development, and it indeed influences social stability and people’s property security. The consequences of accidents caused in sluice will be more serious than that in common facilities’ accidents.Sluice safety appraisal is the fundamental work of sluice project management. The purpose of BeiDianzi sluice appraisal is to eliminate the hidden danger existed in the operation of sluices, restore the function of original sluices and keep the sluice project complete. The appraisal work provides certain reference to the rest of safety appraisal work and could gradually popularize concrete ultrasonic rebound synthetic method.The appraisal of lock site safety is the important step of safety appraisal work., The test items are supposed to reflect the current circumstances of the sluice project security and to provide necessary parameters for recheck computation., Thetest items in Bei Dianzi sluice includes, the basic engineering properties of foundation soil and packing soil; the integrity of the masonry structure; the effectiveness and integrity of Seepage and permeability control facilities; the strength deformation and durability of Concrete structures and sluice gate.; The safety of the hoist and electrical equipment; the effectiveness of the observing facilities.The recheck computation of sluice gate is an empirical analysis based on the basic data calculation and the relevant regulations of sluice safety.The purpose of it is to analyze the hidden troubles in sluice, explain the reason for the dilapidated sluice, and give the corresponding conclusions so as to lay a solid foundation for the further work of security appraisal expert group. Sluice engineering check computation is an important step in the process of the safety appraisal of sluices as well as an important method to reveal the reasons of dilapidated sluices.Bei Dianzi sluice is assessed as the second level sluice after the comprehensive evaluation in terms of data testing, site safety analyzing as well as the recheck calculating of the main structure.
