提高混凝土浅圆仓气密性综合措施与检测方法

Comprehensive measures and detection methods to improve the air tightness of concrete shallow round silos

混凝土浅圆仓的气密性是安全储粮的基础,为保证浅圆仓的气密性,首先应在浅圆仓土建施工过程中加强过程控制,如混凝土配合比、混凝土的浇筑振捣、混凝土的养护和滑膜提升控制等;其次加强预埋件和预留洞口施工控制也有利于提高浅圆仓的气密性;再次加强设备和附件安装质量控制,浅圆仓的气密性也会得到有效提高;最后选用合理的气密性检测方法,有利于验证浅圆仓的气密性效果和及时修复缺陷。

The airtightness of the reinforced concrete squat silo is the foundation of safe grain storage.In order to ensure the airtightness of the silo,the process control should be strengthened in the process of silo civil construction,such as concrete mix ratio,concrete pouring vibration,concrete maintenance and sliding film lifting control,etc..Secondly,strengthening the embedded parts and reserved hole construction control is also conducive to improve the airtightness of the silo;the airtightness of silo can be effectively improved by strengthening the quality control of installation of equipment and accessories.Finally,it is beneficial to verify the airtightness effect of silo and to repair the defects in time.
