Embodiment Construction
[0034] Such as Figure 1 to Figure 4 As shown, a method for plane leakage detection of an ultra-deep foundation pit enclosure structure includes the following steps:
[0035] (1) The inspection work area of foundation pit enclosure structure is divided and marked:
[0036] The principle of uniform division is adopted, and the length deviation of each detection area is within ±1m. After uniform division, if some area is not included in any detection work area and its size does not reach the length of the detection work area, it will be marked as non- Normal detection work area; the invention divides the detection work area evenly, and the difference in size between them or the number of enclosure mechanisms is small. The same sensor mounting bracket can be applied to each detection work area, and can be perfectly adapted to each other. There is no need to re-arrange the sensors, which greatly reduces the workload, thereby improving the work efficiency of the detection projec...
