| Abstract: | Based on the combined rail-cum-road viaduct project in Singapore Reclamation,this paper introduces the application of steel sheet pile during the excavating and supporting process of pile cap and the effective length of the steel sheet pile.The checking of supporting and circuit purlin struc-tures,erection of steel sheet pile and circuit purlin and demolishing points are introduced in detail. The practical application of this project shows that the support technology of sheet pile has superior engineering properties which can not only satisfy the safety requirements of construction but also en-sure environmental protection and conservation. |
