灌注樁施工共分四個過程：鉆孔、清孔、鋼筋籠制作安裝、澆灌水下砼。
其一，鉆孔，共分六個步驟。
(1)、準備工作；
⑵、鋼護筒埋設；
§ 1 Engineering Overview
High-rise bridge, located in the tower's first aqueduct, aqueduct in the high-rise buildings to 1 # 0 # lines between the lines, frame stand tall above the aqueduct body # 1 slot, is to address the provincial highway 57 high-rise aqueduct line (green Dai line) across Aqueduct and set up a small subsidiary of Bridge Engineering. Tall highway bridge by steam - 20, linked to -100, deck net width 8.60M design. Bridge width 9M, bridge length of 12M, the assembled hollow reinforced concrete bridge decks, reinforced concrete crash bars located on both sides of the bridge deck elevation as the top 22.068M, with the original road longitudinal slope of 5% is connected to the bridge on both sides length on each side of the road embankment 50M, W 9M, high-rise township government side of the road by pouring 20CM 250 # thick concrete, the town side of the road by a large shop in Beijing 18CM thick hot asphalt mix gravel. Abutment piles by drilling two columns of reinforced concrete structures, pile diameter D = 1.0M, pile length 6.465-15.46M, pile size type as the pile, pile tip are inserted into the weathered bedrock surface 50CM floor above.
§ 2 Construction program brief
1, foundation excavation and foundation engineering
Pile is divided into four processes: drilling, clean hole, reinforcement cage fabrication and installation, irrigation underwater concrete.
First, drilling, consists of six steps.
(1), preparatory work;
⑵, Steel Casing;
