Pile hole perpendicularity and hole diameter tester for cast-in-situ bored pile
The invention provides a pile hole perpendicularity and hole diameter tester for a cast-in-situ bored pile. The tester comprises a base, supporting legs, measuring rods, springs, a movable rod and a pressing rod, wherein a groove is formed in the base, horizontal scale lines are arranged beside the groove, and the pressing rod penetrates through the groove; a first connecting device is arranged at the bottom of the pressing rod, a second connecting device is arranged on the movable rod, and the second connecting device is arranged below the first connecting device; the plurality of measuring rods are arranged in a circumferential mode; the top ends of the measuring rods are hinged to the first connecting device, the springs are in one-to-one correspondence with the measuring rods, and the springs are connected with the second connecting device and the measuring rods; and vertical scale lines are arranged on the pressing rod. Compared with the prior art, the tester has the advantages that the redundant steps of taking out the tester and readjusting the tester due to the fact that the tester is not attached in place during perpendicularity measurement are not needed; and meanwhile, the value of the hole diameter is measured through the horizontal scale lines on the base, so that the operation is easier, and the reading is convenient.
本发明提供一种钻孔灌注桩桩孔垂直度和孔径检验器。所述检验器包括基座、支腿、测杆、弹簧、活动杆和按压杆，所述基座上设有凹槽，所述凹槽的旁侧设有水平刻度线，所述按压杆穿过所述凹槽；所述按压杆的底部设有第一连接装置，所述活动杆上设有第二连接装置，所述第二连接装置设于所述第一连接装置的下方；所述测杆呈圆周布设有多个；所述测杆的顶端与所述第一连接装置铰接，所述弹簧与所述测杆一一对应，所述弹簧连接所述第二连接装置和测杆；所述按压杆上设有竖向刻度线。与相关技术相比，本发明无需在测量垂直度时因贴合不到位而取出检验器重新调整等多余步骤；同时，基座上的水平刻度线测出孔径的值，更易于操作且读数方便。
