Implementation method for ectopic observation of water level of dewatering well

The invention provides an implementation method for ectopic water level observation of a precipitation well, belongs to the field of precipitation wells, solves the problem that the real water level elevation of the precipitation well cannot be known in the prior art, and comprises the following steps: step S01, inserting a precipitation well pipe into a preset part of a foundation pit; s02, the dewatering well pipe located above the bottom plate is cut off, and then a well mouth of the cut dewatering well pipe is sealed through a well mouth sealing device; and S03, the water level measuring device and the cut dewatering well pipe or the well mouth sealing device are connected through a connecting pipe, and the connecting pipe is buried below the bottom plate. The problem of water level observation when the underground water level is higher than a dewatering well pipe wellhead can be solved. 本发明提供了一种降水井异位观测水位的实施方法，属于降水井领域，它解决了现有无法得知该降水井的真实水位标高等问题，包括如下步骤：步骤S01：将降水井管插入基坑预设部位；步骤S02：割除位于底板上方的降水井管，然后用井口密封装置密封住切割后的
