桥梁钻孔灌注桩质量保证措施探讨

Discussion of the measures to assure the quality of bore-hole pile for the bridge

钻孔灌注桩技术在基础工程领域中占据了主导地位 .钻孔灌注桩是采用不同的钻孔方法 ,在地层中按要求形成一定形状 (断面 )的井孔 ,达到设计标高后 ,将钢筋骨架放入孔中 ,再灌注混凝土 ,成为桩基础的一种工艺 .从成孔质量保证、混凝土配合比优化设计等几方面对桥梁钻孔灌注桩质量保证措施进行阐述 .

Bore-hole pile technique is a predominant in the base construction field.The technique of adopts all kinds of drilling methods in order to form holes with ordered shape.When the depth of the hole came up to the standard,put the steel bone into it and poured concrete in it.This method is a new technology,which is composed of assurance of the quality of holes,quality of raw materials,optimization for the ratio of concrete mixure the quality of the construction measures and so on.
