Test pile cap pouring method
The invention provides a test pile cap pouring method, and relates to the technical field of building construction.The test pile cap pouring method comprises the steps that a forming hole from top to bottom is formed in the ground; the forming hole comprises a first hole and a second hole which are communicated up and down and are coaxial; the pile body casing is lowered into the second hole; concrete is poured into the pile body casing to the transition position of the first hole and the second hole through the guide pipe; the pile body casing is taken out, and a discharging port of the guide pipe is kept to be located below the liquid level of concrete in the second hole all the time; the hopper is disconnected from the top surface of the conduit; the pile cap casing is aligned to the first hole and lowered till the top face of the guide pipe is higher than the top face of the pile cap casing, and the pile cap casing continues to be lowered till the lower end of the pile cap casing is located at the transition position of the first hole and the second hole; connecting the hopper and the conduit; and concrete is poured until sediment in the second hole is completely discharged, and the concrete liquid level is flush with the top face of the pile cap pile casing.
本发明提供了一种试桩桩帽灌注方法，涉及建筑施工的技术领域，试桩桩帽灌注方法包括：在地面上形成自上而下的成型孔；成型孔包括上下连通且同轴的第一孔和第二孔；将桩身护筒下放至第二孔内；利用导管向桩身护筒内灌注混凝土至第一孔和第二孔的过渡位置；取出桩身护筒，且保持导管的出料口始终位于第二孔内混凝土液面以下；料斗与导管的顶面断开；将桩帽护筒对中第一孔，并下放至导管顶面高出桩帽护筒顶面，使桩帽护筒继续下放至其下端位于第一孔和第二孔的过渡位置处；连接料斗和导管；灌注混凝土至第二孔内沉渣全部排出，混凝土液面与桩帽护筒顶面持平。
