深水承台连续排桩加壁板组合式围堰施工技术

Construction Technology of Continuous Row Pile and Wall Plate Combined Cofferdam for Deep Water Bearing Platform

复杂地质情况下的深水承台基坑施工中,依然缺少比较成熟的施工工艺和方法。本文提出的连续排桩+壁板组合式围堰施工技术,是对深厚卵石地层深水承台围堰施工工艺的进一步创新、丰富和完善。通过将该施工技术应用于实际工程中,取得了很好的经济效益与社会效益。可见,该施工技术具有较高的工程应用价值。

In the construction of deep water cap foundation pit under complex geological conditions, there is still a lack of relatively mature construction technology and methods. The construction technology of continuous row piles + wall slab combined cofferdam proposed in this paper was a further innovation, enrichment and perfection of the con. struction technology of deep water cap cofferdam in deep pebble stratum. By applying this construction technology to practical projects, good economic and social benefits had been achieved. It can be seen that the construction technolo. gy has high engineering application value.
