高压旋喷技术自20世纪70年代从日本引进我国,1972年由铁道部科学研究院率先研究此项工作,于1975年正式用于工程建设,由于其实用性,目前此技术已经在全国各地各个专业方向推广应用,具有良好的前景。本文以四川成都地区一高层建筑工程为实例,分析高压旋喷桩复合地基在工程建筑的设计以及施工,根据工程设计结合现场实际施工设备及施工工艺、施工经验,总结施工中需要注意的问题及控制要点。
High-pressure rotary jet technology has been introduced into Japan from Japan in the 1970s. In 1972, it was first studied by the Ministry of Railways Research Institute of Science and Technology and formally used for engineering construction in 1975. Due to its practicality, this technology has been applied all over the country Promote professional applications, with good prospects. In this paper, a high-rise building project in Chengdu, Sichuan Province as an example, analysis of high-pressure rotary jet grouting composite foundation in the engineering design and construction of the building, according to the design of the site with the actual construction equipment and construction technology, construction experience, summarizes the construction needs attention and Control points.
