So in such a formation construction,it is important to use the technology of drilling mud back to tank to balance the pressure of the loose layer and prevent the borehole collapse.
所以在这种地层中施工,利用泥浆回灌钻孔技术有效地平衡松散层压力不使其垮塌尤为重要。
With the restriction of construction technology,sediment at the tip of bored pile in slurry wall is difficult to be cleared,and soil there and aroud pile is disturbed easily,so the vertical bearing capacity of a single pile will be reduced to some extent.
受施工工艺限制,泥浆护壁钻孔灌注桩桩端沉渣不易清除,桩端及桩周土较易扰动,导致单桩承载力有一定程度的降低,通过后注浆技术,可有效解决此问题。
In this article,authors introduce pile foundation drilling slurry used in Sutong Bridge,and mainly compare preparation and application of high quality PHP slurry with green SM slurry’s.
介绍苏通大桥桩基钻孔泥浆,主要对优质PHP泥浆和SM环保泥浆配制和使用进行对比。
