灌注桩后压浆技术及其在工程中的应用

Post grouting technology of cast-in-place pile and its application in engineering

灌注桩后压浆技术 ,不仅有效避免了施工中容易出现的桩底沉渣厚、桩壁土体松软等问题 ,而且还可在桩长、桩径一定的情况下大幅度提高单桩承载力 ,使灌注桩施工工艺中长期存在的一系列问题得到彻底解决。指出只有全面了解并掌握后压浆施工工艺 ,才能使该技术得到大力推广和广泛应用 ,使其为工程建设发挥更大的作用。

The post grouting technology of cast in place pile can not only avoid the problems as thick sediment on its toe and soft soil of pile lining but also enhance the bearing capacity of single pile with fixed length and diameter. This technology solves serials problems of construction technology of cast in place pile. At last author point out that the construction technology must be grasped to push the popularization and wide application of this technology.
