短桩基础是近年来基础工程中出现的一种新技术。有的采用预制桩,也有的采用抽管法或钻孔法施工的灌注桩,我们采用的是钻孔灌注桩。扩底短桩基础分为两种,即爆扩短桩和机具扩底短桃。今年我省各设计和施工部门都以爆扩短桩为主,以省建设厅第二工程公司为例,已在建筑面积为一万二千多平方米的一至三层民用建筑中推广使用了这种新型基础,桩数达900根之多。实践证明,短桩基础富有强大的生命力,深受群众欢迎。发展前途是十分广阔的。
The short pile foundation is a new technology that has emerged in basic engineering in recent years. Some use prefabricated piles, and some use cast-in-place piles or boreholes. We use cast-in-place piles. There are two types of bases for squeezing short-piled piles, namely, explosion-expanded short piles and machine-expanded short peaches. This year, all design and construction departments in our province mainly use explosion-expanded short piles. Taking the second construction company of the Provincial Construction Department as an example, it has been promoted in one-to-three-story civil buildings with a building area of over 12,000 square meters. This new type of foundation has as many as 900 piles. Practice has proved that the short-piles foundation is full of strong vitality and has been welcomed by the masses. The future of development is very broad.
