Cast-in-situ bored pile head height measuring device

The utility model relates to a cast-in-situ bored pile head height measuring device which comprises a control rod, the bottom face of the control rod is connected with a net bag, the net bag is in a funnel shape, the top face of the net bag is provided with a detection device, and the detection device is connected with the control rod in a sliding mode. The height of the pile head is indirectly obtained by measuring the rising height of the detection device under the buoyancy of slurry, meanwhile, measurement errors are avoided, concrete is fished out through the net bag, whether the fished-out concrete is complete or not is checked, if the fished-out concrete is complete, the floating height of the detection device is the height of the pile head, and if the fished-out concrete is not complete, the steps are repeated. 本实用新型涉及钻孔灌注桩桩头高度测量装置，包括控制杆，所述控制杆底面连接网兜，所述网兜呈漏斗状，所述网兜顶面设置探测装置，所述探测装置与控制杆滑动连接。本实用新型通过测量探测装置在泥浆的浮力下升高的高度，间接得出桩头的高度，同时避免测量失误，通过网兜将混凝土捞出，查看捞出的混凝土是否完整，如完整，探测装置上浮的高度即桩头的高度，如不完整，重复步骤。
