Construction Technology of Semi Top-Down Construction Method for Shield Working Well Structure in Costal Water-Rich and Weak Stratum
Aiming at the requirement of tight construction time and heavy task,the advantages and disadvantages and feasibility of using forward method,reverse method and semi-reverse method are compared according to the structural characteristics of the working well,and the semi-reverse method is finally adopted.The results show that the semi-reverse method can effectively guarantee the construction period and construction quality.
