Description

[0002] In hydrogeological exploration, it is necessary to collect rock and soil samples underwater and monitor groundwater levels. The use of telescopic connection devices for water drilling guide casing can help ensure the accuracy and stability of drilling and improve the reliability of exploration data. For natural rivers such as the mainstream of the Yellow River, the water flow is turbulent, and the water level fluctuates greatly during water drilling. The water flow rate and direction will change, making it difficult to lower and fix the hole protection casing. The hole protection casing often needs to be loaded and unloaded, which affects the construction progress and is prone to bending, deformation and fracture. The expansion and contraction of the casing needs to be considered.

[0003] During the use of existing drilling guide casing, due to the fast water flow rate, the casing that was previously inserted vertically will deviate with the direction of water flow. If it is not adjusted to the relative direction in time, it is difficult for the casing to remain vertical and cannot be used stably for a long time. In addition, the inner and outer casings will collide, causing the circulating mud to leak inside and outside. During testing, it cannot make rapid changes according to the water level, which has certain limitations. Utility Model Content
