本文首先简要介绍了PHP泥浆在诸多传统材料中占据的绝对优势,然后重点介绍了PHP泥浆的制备过程中所需要的材料和制备工艺,最后,从两方面分析了PHP泥浆在大直径钻孔桩施工中的技术,分别是PHP泥浆的循环结构和PHP泥浆在大直径钻孔桩中的施工。通过以上内容,分析了采用PHP泥浆提高大直径钻孔桩施工速度这一问题。 This article first briefly introduced the PHP mud in many traditional materials occupy the absolute advantage, and then focuses on the PHP mud preparation process required materials and preparation process, and finally, from two aspects of PHP mud in the large diameter bored pile Construction of the technology, namely, the circulation structure of PHP mud and PHP mud in large diameter bored pile construction. Through the above, the problem of using PHP mud to increase the construction speed of large diameter bored pile was analyzed.
