Method for measuring displacement of slope crest and slope shallow soil body of foundation pit
The invention discloses a method for measuring displacement of a slope crest and a slope shallow soil body of a foundation pit, and belongs to the field of foundation pit safety. Comprising the steps of determining the number and positions of monitoring points according to engineering foundation pit design drawings and specifications; the foundation pit monitoring points simultaneously determine the number and the positions of inclinometer pipes; installing an inclinometer pipe, and centrally fixing 28mm galvanized round steel on the inclinometer pipe through 6mm round steel in the inclinometer pipe; two connecting rods in the transverse direction and the longitudinal direction are welded to round steel in the inclinometer pipe, and a pointer is arranged; a monitoring point is manufactured, a cross mark with the width of 2 mm is cut on the top of galvanized round steel with the length of 200 mm and the diameter of 20 mm, and graduated scales in the transverse direction and the longitudinal direction are welded to the monitoring point through flat iron; the position of the graduated scale is determined according to the position of the pointer determined by the connecting rod, and the monitoring point round steel is smashed into the soil body and is 50mm above the ground; the leveling tube is arranged at the top of the inclinometer tube, and whether the soil body deviates or not can be judged according to whether bubbles of the leveling tube deviate or not. According to the invention, slope crest and shallow soil body changes can be rapidly monitored.
本发明公开了一种测量基坑边坡坡顶及边坡浅层土体位移的方法，属于基坑安全领域。包括根据工程基坑设计图纸及规范确定监测点数量及位置；基坑监测点同时确定测斜管数量及位置；安装测斜管，测斜管内将28mm镀锌圆钢通过6mm圆钢居中固定在测斜管上；将横纵方向两根连接杆焊接在测斜管内圆钢上，并设置好指针；制作监测点，使用200mm长直径为20mm的镀锌圆钢在顶部切割2mm宽十字标志，将横纵两个方向的刻度尺通过扁铁与监测点进行焊接；连接杆所确定指针位置确定刻度尺位置，将监测点圆钢砸入土体，出地面50mm；测斜管顶部设置水准管，可根据水准管气泡是否偏移判断土体是否发生偏移。本发明实现了快速监测坡顶和浅层土体变化。
