这种桩适用于轻型商业建筑和民用建筑,适合作人行道、停车场、庭院围墙、游泳池底板、公共建筑等用的杆和柱。螺旋桩分锥形和圆柱形两种,锥形长10英尺,圆柱形长5～10英尺,直径8 1/2英寸(锥形桩顶端直径为6 1/2英寸)。螺旋节距为1 3/4英寸。可按需要长度把它们叠接起来。一次配制的6000磅/平方英寸混凝土,可浇注8根10英尺长的桩。橡胶衬里的模子悬挂在架空轨道的钩子上。料从顶端浇入,浇灌时辅以振动。两小时后模子移开,使桩悬挂成排。10
The piles are suitable for light commercial buildings and civil buildings and are suitable for use as poles and columns for sidewalks, parking lots, yard walls, swimming pool floors, and public buildings. The spiral piles are tapered and cylindrical in shape. They are 10 feet long, 5 to 10 feet in length, and 8 1/2 inches in diameter (6 1/2 inches in diameter at the tip of the cone). The spiral pitch is 1 3/4 inch. They can be stacked together according to the length required. 6,000 pounds per square inch of concrete that is dispensed at a time can be poured into eight 10-foot long piles. The rubber-lined mold hangs on the overhead rail hooks. The material is poured from the top and is assisted by vibration when it is poured. After two hours the mold was removed and the piles were suspended in rows. 10
