Application Researches on Lasson Steel Sheet Pile Based on Foundation Pit Support Close to Railway Bridge
As a lightweight, fast, airtight, flexible foundation pit supporting structure, lasson steel sheet pile has obvious advantages of short-cycle and low-cost during the construction of double track railway abutment. However, the influence of insertion and extraction of steel sheet pile to original lines is also very big. Therefore, timely backfill grouting, settlement displacement observation and propermaintenance are needed.
