Long spiral drilling machine and cast-in-place pile construction method
The invention discloses a long spiral drilling machine and a cast-in-place pile construction method. The long spiral drilling machine comprises a spiral drilling rod, a center hole is formed in the spiral drilling rod, and the center hole is connected with a grouting pump; the cast-in-place pile construction method comprises the following steps that drilling is conducted through an auger stem drilling machine; and while the spiral drilling rod is lifted out, grouting is conducted in a drilling hole through the center hole. By means of the method and device, the transportation cost can be reduced, the economic performance can be improved, the construction speed can be increased, the slurry protection wall hole forming efficiency can be improved, and energy conservation and environment protection are achieved.
本申请公开了一种长螺旋钻机和灌注桩施工方法，所述长螺旋钻机包含螺旋钻杆，螺旋钻杆内设置有中心孔，所述中心孔与注浆泵连接。所述灌注桩施工方法包括以下步骤：通过螺旋钻杆钻机进行钻孔；提出所述螺旋钻杆的同时，通过所述中心孔向钻孔内进行注浆。用本申请的方法和装置，能够降低运输成本，提高经济性能，提高施工速度，提高泥浆护壁成孔的效率，节能环保。
