| Abstract: | In view of the problems of traditional steel sheet pile,reinforced concrete open caisson support system,a new type of steel open caisson support system construction technology is proposed.The design principle and construction process of this new steel open caisson are introduced in combination with the example of foundation pit support work in the Weinan heating pipe network project.Practice shows that:this new system has the advantages of light weight,fast installation,revolving use,high efficiency of sinking operation,and strong anti-bending,anti-compression and antioverturning ability,which can effectively solve the technical problems of foundation pit deformation and collapse. |
