Static pressure construction method for PHC pipe pile
The invention relates to the field of pipe pile construction, and particularly discloses a static pressure construction method for a PHC pipe pile. The static pressure construction method comprises the following steps that step (1), measuring and marking are carried out, the installation position of the PHC pipe pile is positioned according to a design drawing, an auxiliary circle is drawn on a soil foundation by taking the center of the design installation position of the PHC pipe pile as a circle point, and the radius of the auxiliary circle is consistent with that of the PHC pipe pile; (2), one or more auxiliary holes are drilled outside the auxiliary circle, the total volume of all the auxiliary holes is 8%-12% of the volume of the PHC pipe pile, the depth of each auxiliary hole is 98%-102% of the press-in depth of the PHC pipe pile, and the minimum distance between each auxiliary hole and the auxiliary circle is 98%-102% of the diameter of the auxiliary circle; (3), the PHC pipe piles are subjected to static pressure at the auxiliary circles; and (4), cement mortar is injected into the auxiliary holes and maintained for 28 d or above. The method has the advantage that the influence on the surrounding soil environment is reduced.
本发明涉及管桩施工领域，具体公开了一种PHC管桩静压施工方法，PHC管桩静压施工方法包括：步骤1），测量划线，根据设计图纸定位PHC管桩安装位置，在土基上以PHC管桩设计安装位置的中心为圆点画出辅助圆，辅助圆的半径与PHC管桩半径一致；步骤2），在辅助圆外钻挖一个或多个辅助孔，所有辅助孔的总容积为PHC管桩体积的8‑12%，每个辅助孔的深度为PHC管桩压入深度的98%‑102%，辅助孔与辅助圆之间的最小距离为辅助圆直径的98%‑102%；步骤3），在辅助圆处静压PHC管桩；步骤4），在辅助孔中注入水泥砂浆并养护28d及以上。本发明具有减少对周边土壤环境的影响的优点。
