Compared with the mud on wall form hole technology , clash stake technology or vibration sink pipe technology used in complex foundation stake forming , it has advantages of no vibration , no pollution , and no noise . in addition , since the concrete pressed into the drill stem sent vibration free concrete to the pump , so it is eas y to ensure the quality of the stake body . compared with the mud on wall and dry work form hole technology , the side obstruction and end obstruction of screw drill press concrete stake have all been accordingly improved , the weight bearing is better , and the transmutation of the complex foundation is less 其中,螺旋鉆孔壓灌混凝土成樁技術自研制以來,已在多項復合地基工程中進行了應用,較好地解決了軟弱地層成孔困難的問題,適應地質條件范圍廣,成樁速度較快,工期短、工效高;與復合地基成樁時的泥漿護壁成孔工藝、振沖樁工藝或振動沉管工藝施工比較,具有無振動、無污染、無噪音的優點;另外,壓入鉆桿內的混凝土為泵送免振混凝土,因此樁體質量易于保證;與泥漿護壁和干作業成孔工藝相比,螺旋鉆孔壓灌混凝土成樁的側阻和端阻都有相應的提高,樁的承載性能較好,復合地基的變形較小。
