沖擊旋轉式錨桿鉆機的研製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製以來，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，因此樁體質量易於保證；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。The study of technical state and development tendency for down - hole safety valve of domestic and foreign
旋沖鉆井技術及裝備的發展現狀和展望Studies have shown, lead impeller nozzle it forms the hole to be equal to size of the nozzle, gush out from light, difficult to arrange bits and realize it cut one layer of advantages effectively ; under the equal condition, rotate the nozzle by oneself, can be designed in accordance with the actual need while vary the size of aperture of hole, gush out the distance longer effectively, it is apt to give play to the role of its pulse broken rock
以此設計出限速部分的參數，且初步討論射流功率與轉速之間的關系。研究表明，內導葉輪噴頭形成鉆孔孔徑與噴頭大小相當，有效噴距小，不易排屑和實現其切向剝層優勢；同等條件下，自旋轉噴頭，成孔孔徑大小可依實際需要設計，有效噴距較長，易於發揮其脈沖破巖作用。Rotary percussion boring
