Description

Limiting device for measuring water level by positioning and measuring exploration drilling hole

Technical Field

The utility model relates to the technical field of investigation, in particular to a limit device for measuring water level by locating and measuring an investigation drilling hole.

Background

The water level depth in the drill hole is accurately measured in the positioning of the drill hole, which is inevitably needed in the investigation work, so as to infer the water level elevation in the drill hole and judge the groundwater flow direction in the field. For flatter sites, the accuracy requirements for groundwater level measurement are relatively higher.

Because the ground at the drilling location is not entirely hardened, flat during field construction, the ground elevation around the drilling hole is often non-uniform, inclined or irregularly shaped. The drilling positioning and the water level measurement are not always performed synchronously, so that when the drilling positioning and the water level measurement are performed on the same drilling, the measurement datum planes or datum points are often selected to be different, so that the deduced underground water level elevation is inevitably error, and the ground underground water flow direction rule cannot be accurately judged.

To solve this problem, the following methods are often adopted in site construction: 1. and (3) drilling positioning measurement is carried out simultaneously when drilling water level measurement is carried out, and the same measurement datum plane or datum point is selected. However, the method is often labor-consuming, has low flexibility and is unfavorable for improving the working efficiency. 2. And selecting a fixed position to be marked as a measuring datum plane or a datum point for measuring the water level of the drill hole and positioning the drill hole. However, this method has the disadvantage that the field mark is often easily damaged, and the water level measurement and the drill positioning are often not done by the same person, which is easily misjudged when the field mark is ambiguous. 3. And (4) leveling the periphery of the drilling hole, and measuring. However, this method has the disadvantage of large workload and large human error.

Therefore, a more efficient device for surveying drill hole positioning measurement and water level measurement is needed.
