Research on Improvement Technology of Construction Technology for Lining Wall of Subway Station
The construction quality of the lining wall in the composite wall of the subway foundation pit is extremely important.Through relevant research,it has been found that the traditional process of the lining wall often leads to quality problems such as honeycomb,pockmarked surfaces,cracking and leakage on the wall surface,which seriously affects the safety and service life of the station structure.The proposed film protection technology for the upper part of the waterproofing steel plate can effectively prevent the pollution of the upper part of the waterproofing steel plate and ensure the waterproofing effect of the waterproof node.The seamless lower axillary angle turning method prolongs the seepage path and improves the quality of construction joints.At the same time,a construction joint is reduced at the lower axillary angle,thus improving the appearance quality.The fully automatic intelligent control attached vibration system realizes the whole process of mechanized vibration operation,and improves the uniformity and compactness of concrete.The water-saving and moisturizing curing film strengthens the control of the concrete curing process.Through the relevant tests carried out on the construction site and the operability and practical application of the improved process by means of targeted research,the construction quality of the lining wall is improved as a whole,which promotes the development the subway station towards high standards and high quality.
