大、中型厂房柱基施工中,当混凝土垫层施工好后,就要进行杯形基础或其它基础的浇捣工作。为了避免差错,严格控制基础中心线,就必须对基坑定位桩进行校正。这项校正工作,如果采用支三角架配以锤球对中,工作量繁杂,进度太慢。再加上有风天气和基坑土的影响,视线不通,校正工作就更困难了。往往不能满足工程进展的需要。针对这种情况,我单位创
In the construction of large and medium-sized factory building foundations, after the construction of concrete cushions is completed, a cup-shaped foundation or other basic pouring work shall be carried out. In order to avoid mistakes and strictly control the basic centerline, it is necessary to correct the foundation pit piles. This correction work, if using a tripod with hammer ball centering, the workload is complicated, the progress is too slow. In addition to the effects of windy weather and soil on the foundation pit, the sight line is not clear and correction work is even more difficult. Often can not meet the needs of the progress of the project. In response to this situation, my unit created
