| Abstract: | The design depth of water-stop curtain wall was 34.6m under natural ground with complex surrounding environment and geological conditions. Based on the comprehensive analysis, various construction processes were explored. Three axis mixing cement pile water-stop curtain wall were constructed on the east, west and south sides and high rotary jet grouting water-stop curtain wall was used on north side. The unfavorable factors of narrow site, complex geological conditions and environment were overcome with good water-stop effect. |
