Cast-in-place pile sediment thickness measuring scale and using method thereof

LIU ZHONGZHENG

The invention discloses a cast-in-place pile sediment thickness measuring scale and a using method thereof, and belongs to the technical field of sediment thickness measurement. The device comprises a shell cylinder, and supporting frames are arranged on an outer ring of the shell cylinder at intervals; and a rotating shaft is arranged in the shell cylinder, a soft paper graduated scale is arranged on an outer ring of the rotating shaft in a surrounding manner, a hard contact piece is arranged on the outer ring of the soft paper graduated scale, and a contact rod is mounted at the bottom of the hard contact piece. The error convention that the sediment thickness is judged only according to construction experience is changed, the tip of the contact rod is in contact with a bearing layer, the contact rod is in contact with the hard contact piece, so that the contact hard contact piece and the soft paper graduated scale are driven to move together relative to the shell cylinder, when the relative movement is finished, the numerical value in a scale bracket corresponding to an indicator is the measured sediment thickness, and the cast-in-place pile sediment thickness measuring scale has the advantages of quickly, conveniently and accurately measuring the sediment thickness and improving the detection efficiency and the measurement precision.

本发明公开了一种灌注桩沉渣厚度测量尺及其使用方法，属于沉渣厚度测量技术领域。本发明包括外壳筒体，外壳筒体的外圈间隔设置有支撑架；所述的外壳筒体内部设置有转动轴，转动轴的外圈环绕设置有软纸刻度尺，软纸刻度尺的外圈设置有硬质触片，硬质触片的底部安装有触杆。本发明改变仅凭施工经验判断沉渣厚度的错误惯例，通过触杆顶尖接触持力层，触杆会接触硬质触片，从而带动接触硬质触片、软纸刻度尺一起相对外壳筒体运动，当相对运动结束时，指示器所对应刻度括号内的数值即所测沉渣厚度，具有快速便捷、准确地测量沉渣厚度，提高检测效率和测量精度的优点。
