On Receiving Construction Technology of Shield Steel Sleeve in Water-rich Sand Layer
In order to study the steel sleeve receiving construction technology of water-rich sand shield,combined with the actual situation of Xisha Road Station to Guoji Road Station,based on the key and difficult points of construction,the application of steel sleeve receiving construction technology in water-rich sand shield construc-tion was analyzed.It is concluded from practice that steel sleeve reception is an important and difficult point in shield construction.In the concrete construction,it is necessary to combine the geological and hydrological condi-tions of the area where the project is located,and the steel sleeve is supplemented by grouting water sealing and curved steel plate sealing,so as to realize the shield steel sleeve reception construction with small space in ex-change for large space,which can effectively overcome the influence of the receiving end reinforcement quality in the receiving process of the shield.By effectively solving the process conflict between horizontal freezing method and traditional shield receiving,the construction process is easier to control,while ensuring the smooth comple-tion of steel sleeve receiving and improving the shield construction efficiency and quality,which can provide cor-responding reference and guidance for similar engineering construction.
