Abstract
Description
Technical Field
[0001] The present application relates to the field of gravity flow well design, and in particular, to a gravity flow well. Background Art
[0002] The principle of gravity flow well is to use gravity and hydrostatic pressure to achieve liquid transportation. The basic idea of this principle is to use the gravity of the earth as the power source of the liquid, and transport the liquid from one place to another through a pipeline system that is easy to design and maintain. In this process, the liquid will not need any external power because the gravity of the earth will be able to transport the liquid to the destination.
[0003] A common gravity flow well includes a wellbore and a pipe connected to the bottom of the wellbore. Sewage flows into the wellbore from one pipe and then flows out of the wellbore from another pipe on the wellbore. According to the principle of thermal expansion and contraction, the pipe laid in summer is tightly connected to the wellbore. In winter, the diameter of the pipe decreases, resulting in a gap between the pipe and the wellbore. Sewage overflows from the gap, causing environmental pollution. Summary of the invention
[0004] The content of this application is used to introduce concepts in a brief form, which will be described in detail in the detailed implementation section below. The content of this application is not intended to identify the key features or essential features of the technical solution claimed for protection, nor is it intended to limit the scope of the technical solution claimed for protection.
[0005] In order to solve the technical problems mentioned in the above background technology part, some embodiments of the present application provide a gravity flow well, including: a bottom plate; a wellbore, the lower end of which is in contact with the upper surface of the bottom plate, and the lower part of the wellbore forms a first through hole and a second through hole opposite to each other; a first pipe, one end of which extends into the first through hole and is connected to the first through hole; a second pipe, one end of which extends into the second through hole and is connected to the second through hole; a first ring, the inner ring of which is sleeved on the outer wall of the first pipe, and the outer ring is embedded in the first through hole; a second ring, the inner ring of which is sleeved on the outer wall of the second pipe, and the outer ring is embedded in the second through hole.
[0006] Furthermore, the first pipe and the second pipe are both made of PE material.
[0007] Furthermore, the first ring and the second ring are both made of corrosion-resistant metal materials.
[0008] Furthermore, the first collar and the first pipe are integrally formed, and the second collar and the second pipe are integrally formed.
[0009] Furthermore, concrete is filled in the first through hole and connected to the first pipe, and the concrete fits with the first sleeve ring; concrete is filled in the second through hole and connected to the second pipe, and the concrete fits with the second sleeve ring.

[0011] Furthermore, it also includes: a guide block; the guide block is placed in the lower part of the wellbore, and a guide groove is formed at the upper end of the guide block, one end of the guide groove is connected to the first pipeline, and the other end of the guide groove is connected to the second pipeline.
[0012] Furthermore, the diameter of the first pipe is smaller than the diameter of the second pipe, and the width of the guide groove gradually increases from an end connected to the first pipe to an end connected to the second pipe.
[0013] The beneficial effects of this application are:
[0014] When the first pipe and the second pipe shrink due to cold, the sewage in the wellbore flows into the gap between the wellbore and the first pipe and the gap between the wellbore and the second pipe, and is finally blocked by the first ring embedded in the first through hole and the second ring embedded in the second through hole, preventing sewage from overflowing and protecting the nearby environment.

[0028] Reference Figure 1-3 ,
[0029] A gravity flow well comprises: a bottom plate 1, a well shaft 2, a first pipe 5, a second pipe 6, a first collar 7 and a second collar 8. The bottom plate 1 and the well shaft 2 are prefabricated parts cast with concrete. The lower end of the well shaft 2 is fixedly connected to the upper surface of the bottom plate 1 by concrete. The lower part of the well shaft 2 forms a first through hole 3 and a second through hole 4 opposite to each other, one end of the first pipe 5 extends from the outside of the well shaft 2 into the first through hole 3, and one end of the second pipe 6 extends from the outside of the well shaft 2 into the second through hole 4. The first collar 7 is located in the first through hole 3, the inner ring of the first collar 7 is fixedly connected with the outer wall of the first pipe 5 in a watertight sleeve, and the outer ring of the first collar 7 is embedded in the inner wall of the first through hole 3, so that when the first pipe 5 contracts, the first collar 7 forms a watertight connection with the first through hole 3. The second ring 8 is located in the second through hole 4, and the inner ring of the second ring 8 is watertightly sleeved and fixed to the outer wall of the second pipe 6, and the outer ring of the second ring 8 is embedded in the inner wall of the second through hole 4, so that when the second pipe 6 contracts, the second ring 8 forms a watertight connection with the second through hole 4.
[0030] Specifically, the first pipeline 5 and the second pipeline 6 are both made of PE material, so that the first pipeline 5 and the second pipeline 6 are light in weight and also corrosion-resistant.
[0031] Specifically, the first ring 7 and the second ring 8 are both made of corrosion-resistant metal materials, specifically stainless steel.
[0032] Specifically, the first ring 7 and the first pipe 5 are prefabricated parts that are integrally injection-molded together, and the second ring 8 and the second pipe 6 are prefabricated parts that are integrally injection-molded together, which are convenient for workers to directly use after being transported to the construction site.
[0033] Specifically, concrete is filled in the first through hole 3 and connected to the first pipe 5, concrete is filled on both sides of the first ring 7, the concrete on both sides fits with the first ring 7, and the first ring 7 is clamped in the middle to improve the water tightness between the first ring 7 and the first through hole 3. Concrete is filled in the second through hole 4 and connected to the second pipe 6, concrete is filled on both sides of the second ring 8, the concrete on both sides fits with the second ring 8, and the second ring 8 is clamped in the middle to improve the water tightness between the second ring 8 and the second through hole 4.
[0034] Specifically, the lowest point of the first through hole 3 is higher than the lowest point of the second through hole 4 , and the sewage enters the wellbore 2 from the first through hole 3 along the first pipe 5 , and under the action of gravity, the sewage flows to the second through hole 4 and finally flows out of the wellbore 2 from the second pipe 6 .
[0035] Specifically, it also includes: a guide block 9. The guide block 9 is a component cast by concrete at the lower part of the wellbore 2. A guide groove 10 is formed at the upper end of the guide block 9. The end of the guide groove 10 facing the first through hole 3 is connected to the first pipe 5, and the end of the guide groove 10 facing the second through hole 4 is connected to the second pipe 6. After the sewage enters the wellbore 2 from the first pipe 5, it flows through the guide groove 10 and finally flows out of the wellbore 2 from the second pipe 6. The guide block 9 guides the sewage and reduces the probability of sewage accumulating in the wellbore 2.
[0036] Specifically, the diameter of the first pipe 5 is smaller than the diameter of the second pipe 6, and the width of the guide groove 10 gradually increases linearly from the end connected to the first pipe 5 to the end connected to the second pipe 6. Since the impact force of the sewage flowing from the first pipe 5 into the wellbore 2 is relatively large, according to the relationship between the liquid flow rate and the cross section, the gradual linear increase in the width of the guide groove 10 is conducive to the gradual deceleration of the sewage in the guide groove 10, and finally flows out of the second pipe 6 at a flow rate lower than that of the first pipe 5 into the wellbore 2. Thereby reducing the impact of the sewage on the inner wall of the wellbore 2 and the second pipe 6, and improving the service life of the entire gravity flow well.
[0037] The above descriptions are only some preferred embodiments of the present disclosure and an explanation of the technical principles used. Those skilled in the art should understand that the scope of the invention involved in the embodiments of the present disclosure is not limited to the technical solutions formed by a specific combination of the above-mentioned technical features, but should also cover other technical solutions formed by any combination of the above-mentioned technical features or their equivalent features without departing from the above-mentioned inventive concept.
