轻型井点降水法在水下承台施工中的应用

桥梁水下承台施工过程中,常常由于水的侵扰,造成基坑不稳定,因此如何避免水对基坑的影响一直是桥梁工程中的一个难点。结合工程实践,对水下承台施工中轻型井点降水法的施工方法、应用效果进行阐述,结果表明在桥梁水下承台施工过程中采用轻型井点降水法将具降低成本和缩短工期的优点。

Application of Light Well-Point Dewatering in Construction of Bearing Platform under Water

During the construction of bearing platform under water,foundation pit is usually unstable because of the intrusion of water.Therefore,how to avoid the impact of water on foundation pit is always a difficulty in bridge engineering.Combining with the engineering practice,the paper expatiates on the construction method and application effect of light well-point dewatering in construction of bearing platform under water.The result shows that the application of light well-point dewatering in construction of bridge bearing platform under water can reduce cost and shorten construction period.
