Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for purposes of illustration only and are not intended to limit the invention.

The following describes the implementation of the present invention in detail with reference to specific embodiments.

As shown in fig. 1, in the embodiment of the present invention, a pipeless dewatering well is provided, which comprises a well head 2 disposed in a well hole 1, a water pumping pipe 3 and an air pipe 4 respectively connected to the well head 2, and a filter material 12 and clay 11 buried in the well hole 1.

As shown in fig. 2, the wellhead 2 includes a water filtering bin 8 and a water gas bin 10 disposed below the water filtering bin 8. The water filtering bin 8 and the water gas bin 10 are separated by a partition plate 9. A downpipe 5 penetrating through the partition board 9 is arranged between the water filtering bin 8 and the water-gas bin 10. A one-way valve 6 is arranged in the downpipe 5. Whether the water filtering bin 8 is communicated with the water gas bin 10 or not is controlled by opening and closing the one-way valve 6. In another implementation, the downpipe 5 may not be provided, and an opening may be formed between the filtered water bin 8 and the water and air bin 10, and the check valve 6 may be disposed in the opening.

The top of the water filtering bin 8 is provided with a water permeable plate 7. And a filter material is also filled in the water filtering bin 8. The filtered water sump 8 is used to filter the groundwater infiltrated in the well 1 and to guide the filtered water to the water gas sump 10. One end of the water pumping pipe 3 is arranged at the bottom of the water-gas bin 10, and the other end of the water pumping pipe is arranged outside the well hole 1. One end of the air pipe 4 is arranged at the top of the water and air bin 10, and the other end of the air pipe is arranged outside the well hole 1.

The working principle of the pipeless precipitation well of the utility model is as follows:

when air is pumped from the air pipe 4, negative pressure is formed in the water-air bin 10, the one-way valve 6 is opened, the underground water in the well hole 1 is influenced by the negative pressure and flows into the water-air bin 10 through the water filtering bin 8, when air is added into the air pipe 4, the one-way valve 6 is closed, the air pressure in the water-air bin 10 rises, and the water in the water-air bin 10 is discharged from the water pumping pipe 3.

To sum up, the utility model discloses a no pipe precipitation well including set up in the borehole the well head, respectively with drinking-water pipe and trachea that the well head is connected, the well head including strain the water storehouse and set up in strain the water storehouse of water storehouse below, strain the water storehouse with the water storehouse is linked together through a check valve, the one end setting of drinking-water pipe with the bottom in water storehouse, the other end set up outside the borehole, tracheal one end set up in the top in water storehouse, the other end set up outside the borehole, put into the well head after the pore-forming can, need not the well casing, adopt the suction of atmospheric pressure to act on and extract groundwater, the below-ground does not have the cable conductor, when high-efficient drawing water, does not have the well casing loss, does not have the safety problem that the cable conductor arouses yet.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not intended to limit the present invention, and any modifications, equivalents, improvements, etc. made within the spirit and principles of the present invention should be included within the scope of the present invention.
