  1. 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,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,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,復合地基的變較小。
  2. To ensure the charging pump working reliably, the following measures should be adopted : ( 1 ) adopting modified circular casing to reduce the radial force of the impeller and decrease the seal clearance ; ( 2 ) using radical ribs on impeller and helical sealing on shaft to realize minor pressure differential ; ( 3 ) using back pressure stuffing box to ensure sealing under small packing force ; ( 4 ) adopting self - lubricant flexible graphite stuffing for absorption of solids entering in the graphite in case of leaking

    為確保灌注泵可靠工作,提出改進措施: ( 1 )採用改型環泵體降低葉輪的徑向力,減小軸封間隙,抑制泄漏; ( 2 )採用背葉片降低葉片根部壓頭,獲得微壓,使軸封兩端承受較小壓差; ( 3 )採用密封降低軸封兩端壓差,在保持微壓的同時避免出現負壓,密封效果更好; ( 4 )採用反壓式填料密封結構,在很小的壓緊力下,即可保證密封; ( 5 )採用具有潤滑功效的柔性石墨填料,即使發生軸封泄漏,進入石墨內部的固相顆粒也將隨著石墨的消耗而被井液吸收。
