  • CWSII method was developed to overcome the problems of frequent occurrence in the application of existing downward construction methods, especially in the case of using slurry wall instead of SCW or CIP as a retaining wall. By the improvements in connecting steel beams with the wall, CWSII method is able to ensure the settlement of a steel beam and the diaphragm effect of a slab while reducing the degree of difficulty and the term of works and the cost of construction. As the desired results, CWS method can be applied as a practical downward construction method regardless of the type of retaining wall. In this paper, besides the concept and features of CWSII method, it can be seen that the method can provide reliable and economical performances by comparing with existing methods.

  • CWS I method developed to overcome the problems of frequent occurrence in the application of existing downward construction methods has demonstrated excellent efficiency. However, in the case of using slurry wall instead of SCW or CIP as a retaining wall, the improvements in connecting steel beams with the wall were demanded. Therefore, the study of CWS II method was carried out in order to accomplish the CWS I method reflecting its strong points and to ensure the settlement of a steel beam and to induce the diaphragm effect of a slab while reducing the degree of difficulty and the term of works and the cost of construction. In this paper, the concept and features of CWS II method as well as the progress of execution was discussed by comparing with existing methods.

  • A down construction method is frequently used in these days to reduce popular discontent and to assure sufficient working space at early stage in downtown area. There are two main problems in the existing down construction method. One is a confliction between frame works and excavation works, and the other is a cold joint in retaining wall which is unavoidable due to a sequence of concrete placement and induces a water leakage. Therefore, a new method is needed to overcome these problems. The CWS (buried wale Continuous Wall System) method was developed by authors. By replacing RC perimeter beam with embedded steel wale, the steel frame works of substructure can be simplified and the water leakage can be prevented using continuous retaining wall. Consequently, the improved duality and reduction of construction period can be obtained from CWS method.
