Small-diameter steel pipe pile construction method
The invention discloses a construction method of a small-diameter steel pipe pile. The method comprises the following four steps. The steel pipe pile is assembled, specifically, one end of a pollution discharge sleeve is screwed with the small-diameter threaded section of the drill hole, then one end of a steel pipe body is connected with the large-diameter threaded section of the drill hole, and the pollution discharge sleeve and the steel pipe body form a sleeve structure; drilling construction is conducted, specifically, the assembled steel pipe pile is matched with a multifunctional drilling machine and screwed into a soil layer; after the steel pipe pile reaches the specified depth, the connection between the connecting end of the multifunctional drilling machine and the steel pipe body is relieved and connected with the pollution discharge sleeve; the connection between the pollution discharge sleeve and the drill bit is removed, and the pollution discharge sleeve is pulled out; after dirt in the dirt discharging sleeve is emptied, the method is used in the step of assembling the steel pipe pile; pouring materials are prepared, a grouting pipe of grouting equipment is lowered in the steel pipe body, and grouting is conducted on the steel pipe body; and pile end treatment: after the end opening of the steel pipe body settles, pouring materials are supplemented, and the steel pipe body is ground to be flat. The problems of hole collapse and hole shrinkage during construction of the small-diameter steel pipe pile can be avoided, and the construction efficiency can be improved.
本发明公开了一种小直径钢管桩施工方法；该方法包括如下四个步骤。组装钢管桩：先将排污套管的一端与钻孔的小直径螺纹段旋接，然后将钢管本体一端与钻孔的大直径螺纹段连接，排污套管与钢管本体形成套管结构；钻孔施工：将组装后的钢管桩与多功能钻机配合并旋入土层中；钢管桩至指定深度后解除多功能钻机连接端与钢管本体的连接并与排污套管进行连接；解除排污套管与钻头的连接，拉出排污套管；清空排污套管内污物后用于组装钢管桩步骤中；加压注浆：配置浇注料，在钢管本体内下放注浆设备的注浆管，对钢管本体进行注浆；桩端处理：钢管本体端口出现沉降后，补充浇注料并磨平。本发明可避免小直径钢管桩施工时出现塌孔和缩孔问题，还可施工效率。
