施 工 技 术 总 结

一、工程概况
新湖路（北段）市政工程，地处宝安新中心区。是由宝安区城市建设投资发展公司兴建，宝安区市政工程设计院设计，深圳市全安建设监理有限公司监理，深圳市华侨建筑工程公司第一分公司承建。
施工起点桩号0+060（X22353.464、Y96064.100）、终点桩号0+728.15（X21902.083、Y96556.643），全长668.15m，工程预算造价2997万元。
工程自1995年   月   日开始施工，但由于其他原因在中途于1996年   月   日暂停施工。之后在2000年   月   日由建设单位组织，重新签订承包合同，于2000年9月8日灰复动工，并在2002年10月1日按优良工程正式完成。
二、工程地质地貌特征
本工程施工路段原始地貌为潮间带，后经人工围成若干鱼塘。塘底高程为0.00m～0.8m，水深约为1.0m，塘埂高程2.0m～3.5m。施工段内除塘埂及水域区外，其中在0+150处有一条横穿路基的河道（咸水涌）。而0+060～0+120段全部被人工弃淤覆盖，高程在2.3m～3.8m。
