钻孔灌注桩,简单地说就是就地成孔的施工方法。钻孔灌注桩适用于各种土层,桩径范围广,工艺简单、噪音小、成本低,所以被广泛应用于土木工程之中,尤其常见于公路桥梁施工中。在路桥工程地基处理的时候,必须在了解工程特点的基础上,编制详细的施工方案,但施工技术方面,总是万变不离其宗。本文对钻孔灌注桩的基本概述,准备工作以及其在路桥中的施工技术进行分析。
Bored piles, simply put into place is the construction method. Bored pile is suitable for all kinds of soil, wide range of pile diameter, simple process, low noise, low cost, so it is widely used in civil engineering, especially in highway bridge construction. In the road and bridge engineering foundation treatment, we must understand the project characteristics, based on the preparation of a detailed construction program, but the construction technology, always changing. In this paper, the basic overview of bored piles, preparation and their construction technology in road and bridge are analyzed.
