加筋旋喷桩在南高干渠改造边坡支护的应用

The application of reinforced rotary jet grouting pile in slope support of Nangao main canal reconstruction

结合工程概况及其水文地质条件,根据渠道地质条件对其施工支护方式进行了比选,最终选择单管高压旋喷桩。作为其施工与支护方案,并从加筋旋喷桩的施工工艺、施工参数的确定、钢筋的施工等方面阐述了加筋旋喷桩的施工过程,以保证渠道边坡的稳定和建筑物的安全。

Combined with general condition of construction and hydro-geological condition,the author carries out comparison and selection of construction supporting methods according to canal s geological condition,selects simple-pipe high-pressure rotary jet grouting pile as construction supporting scheme,and illustrates construction process of reinforced rotary jet grouting pile from its construction technology,setting of construction parameters and construction of steel bar,in order to ensure the stability of canal...
