螺纹钻灌注桩施工工艺是一种非常简便的桩基施工法,它较其他基桩施工方法有许多优点。此法施工时噪音低、振动小,适合于在居民稠密的地区施工,而若用普通锤击打桩施工易损坏邻近建筑物,且噪音很大。另外,此法在不稳定土层中特别适用。但在硬土、漂砾等土层中施工时,不易达到要求深度,因为土层 Threaded bored piles construction process is a very simple pile construction method, which has many advantages over other pile construction methods. This method low noise when construction, vibration is small, suitable for construction in densely populated areas, and if ordinary hammering piling easily damaged neighboring buildings, and noisy. In addition, this method is particularly applicable in unstable soil. However, hard soil, boulders and other soil construction, difficult to achieve the required depth, because of soil
