Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1-3, a precipitation well structure for observing water level in different positions comprises a precipitation well pipe 1 capable of being cut, a water level measuring device and a wellhead sealing device 2, wherein the wellhead sealing device 2 is used for sealing a wellhead of the precipitation well pipe 1 after being cut, and the water level measuring device is connected with the precipitation well pipe 1 after being cut or the wellhead sealing device 2 through a connecting pipe 3 buried below a bottom plate. The connection pipe 3 is buried under the bottom plate in order to protect the connection pipe 3 better.
In further detail, the water level measuring device is located above the bottom plate. An excavation surface is selected on the bottom plate, then a pit is excavated downwards, and the water level measuring device is positioned above the bottom plate, so that people can conveniently observe the water level measuring device.
In further detail, the water level measuring device is detachably connected with the connecting pipe 3 through threads. The connecting pipe 3 is welded or screwed to one side of the precipitation well pipe 1 or the wellhead sealing device 2.
The method comprises the steps of cutting off the precipitation well pipe 1 above a bottom plate, sealing a well mouth, welding a connecting pipe 3 at an opening on one side of the precipitation well pipe 1, or connecting the connecting pipe 3 in a threaded manner on one side of the precipitation well pipe 1, or connecting the connecting pipe 3 in a welded manner or a threaded manner on one side of a well mouth sealing device 2, so that the precipitation well pipe 1 is communicated with the connecting pipe 3, certain strength must be provided for each connecting point by welding, looseness is prevented from occurring under the action of air pressure and water pressure, and water leakage at the welding position is prevented. Then the water level measuring device is connected with the connecting pipe 3 through a thread, and the thread connection place needs to adopt a raw rubber belt to process the thread space, so as to prevent water leakage.
All the thread connection modes of the embodiment can be replaced by welding, or other connection modes can be adopted.
