Measurement of Straightness and Verticality of Sheet Piling

摘要

Sheet piling is commonly used in various areas of special construction. Embedded in the ground before carrying out excavation works, sheet piling constitutes an enclosure and protection for the designed excavation. It is a temporary enclosure and protection for excavations made for communication structures, launch shafts built for microtunnel construction, etc. In order to assess the quality of the engineering works related to the construction of sheet piling, measurements were made of straightness and verticality of the sheet piling used for the technological chambers. The measurements concerned two technological chambers of 7.2 and 6.4 m height. Inventory measurements were made using a total station of 1” accuracy and a leveling staff with the appliance of the so-called projection method. The two technological chambers were built in the investment area called “Infrastructure construction for rainwater drainage, water supply and sanitary sewage collection from the John Paul II International Airport Kraków-Balice.”
