Description

Technical Field

[0001] This invention relates to the field of pool structure processing, and more particularly to a method for opening holes on the outside of a sealed pool. Background Technology

[0002] Storing a liquid substance in a tank can effectively reduce environmental pressure. In the wastewater treatment industry, there are many types of tanks, such as equalization tanks, emergency tanks, balancing tanks, biological treatment tanks, sludge tanks, and membrane tanks. In actual production, due to needs such as sewage discharge, pipe blockage, tank switching, and process changes, it is often necessary to create openings in the side walls of the tank to arrange pipelines. The conventional method is to first create through holes in the tank wall, then insert pipes through these holes into the tank, and then have workers enter the tank to seal the gap between the through holes and the pipes with a filling material. However, this method of creating openings has the following drawbacks:

[0003] 1. It requires staff to enter the pool to seal the connection between the through hole and the pipe. However, the pool often has an extreme working environment, and the sewage, toxic gases and odors in the pool can easily cause health problems for the staff.

[0004] 2. Poor sealing performance after sealing treatment can easily cause substances in the pool to leak out from the gaps between the pipes and the through holes;

[0005] Therefore, a more reasonable method for opening holes in the pool is urgently needed to solve the aforementioned drawbacks. Summary of the Invention

[0006] In view of the technical problems of existing technologies that require workers to enter the pool to seal the through holes and pipes, and the sealing effect is not good, the present invention provides a new solution.

[0007] To achieve the above objectives, the present invention provides a method for opening an external hole in a sealed pool body, comprising the following steps:

[0008] Openings: A first through hole and a second through hole are formed on the side wall of the pool body. The first through hole and the second through hole are concentrically arranged, and the cross-sectional diameter of the first through hole is smaller than the cross-sectional diameter of the second through hole. The first through hole is directly connected to the cavity formed by the pool body.

[0009] Preparing for pipe laying: Obtain a first flange sleeve, with the first end of the first flange sleeve passing through the first through hole and extending into the cavity, and the second end having a first sealing flange extending out of the second through hole; the cavity formed by the second through hole is filled and sealed with a filling material;

[0010] Piping: Obtain a flexible hose, the first end of which extends into the cavity through the first flange sleeve, and the second end is sleeved on the second flange sleeve. The second sealing flange of the second flange sleeve is connected to the first sealing flange to form a sealing port. The sealing port is used to connect to an external end cap or a suction pump.

[0011] As an improvement of the present invention, in the hole-opening step, an assembly hole is also provided on the inner end face of the second through hole; in the pre-pipe laying step, the pipe body of the first flange sleeve is also provided with an assembly flange, and the assembly flange is fixedly connected to the assembly hole.

[0012] As an improvement of the present invention, in the pipe laying step, the connection part between the hose and the second flange sleeve is further fitted with a clamp structure.

[0013] As an improvement of the present invention, in the pipe laying step, the type of hose is a steel wire hose.

[0014] As an improvement of the present invention, in the pipe laying step, a sealing gasket is further provided between the first sealing flange and the second sealing flange.

[0015] As an improvement of the present invention, before the opening step, the liquid level in the cavity is positioned below the liquid level line overlapping the axis of the first through hole.

[0016] As an improvement of the present invention, in the pre-pipe laying step, the filling material is one or more of cement or sealing putty.

[0017] The beneficial effects of this invention are as follows: Compared with the prior art, this invention provides a method for opening an external hole in a sealed pool body, comprising the steps of opening a hole, preparing a pipe, and laying a pipe; wherein, in the opening step, a first through hole and a second through hole for assembling a first flange sleeve are formed on the side wall of the pool body; in the preparing pipe step, after obtaining the first flange sleeve, a portion of the first flange sleeve is inserted into the pool body and communicates with the cavity; the portion of the first flange sleeve placed in the second through hole is fixed and sealed by filling with a filling material; in the pipe laying step, after obtaining a flexible hose, the first end of the flexible hose is inserted into the... Inside the cavity, the second sealing flange at the second end of the hose is connected to the first sealing flange to form a sealing port, thus sealing the hose and the first flange sleeve. When there is no need to pump the material in the pool, the end cap is used for sealing. The above method can be completed by the staff outside the pool without entering the pool, which greatly increases the sealing performance and prevents the material from leaking out of the pool. When it is necessary to pump the material in the pool, the material in the pool is pumped out by a suction pump. The sealing port can also be tightly connected to the suction pump, and there will be no leakage. Attached Figure Description

[0028] To more clearly illustrate the present invention, the invention will be further described below with reference to the accompanying drawings.

[0029] In the following description, specific examples of general elections are given to provide a more in-depth understanding of the invention. It is obvious that the described embodiments are merely some, not all, of the embodiments of the invention. It should be understood that the specific embodiments described are for illustrative purposes only and are not intended to limit the invention.

[0030] It should be understood that when the terms “comprising” and / or “including” are used in this specification, they indicate the presence of the said feature, integral, step, operation, element, or component, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, or combinations thereof.

[0031] Storing liquid substances in tanks can effectively reduce environmental pressure. In the wastewater treatment industry, there are various types of tanks, such as equalization tanks, emergency tanks, balancing tanks, biological treatment tanks, sludge tanks, and membrane tanks. In actual production, due to needs such as sewage discharge, pipe blockage, tank switching, and process changes, it is often necessary to create openings in the side walls of the tanks to arrange pipelines. The conventional method is to first create through holes in the tank wall, then insert pipes through these holes into the tank, and finally have workers enter the tank to seal the gap between the through holes and the pipes with a filling material. However, this method has the following drawbacks: 1. It requires workers to enter the tank to seal the gaps between the through holes and the pipes. However, the working environment inside the tank is often quite extreme, and harmful substances such as sewage, toxic gases, and odors can easily cause health problems for workers. 2. The sealing performance after sealing is not good, and substances can easily leak out from the gaps between the pipes and the through holes. Therefore, a more reasonable method for creating openings in tanks is urgently needed to solve the above-mentioned drawbacks.

[0032] To address the problems existing in the prior art, this invention provides a method for opening an external hole in a sealed pool body. Please refer to [link / reference]. Figures 1 to 2 This includes the following steps:

[0033] Step 1, Opening holes: A first through hole 1 and a second through hole 2 are formed on the side wall of the pool body. The first through hole 1 and the second through hole 2 are concentrically arranged, and the cross-sectional diameter of the first through hole 1 is smaller than the cross-sectional diameter of the second through hole 2. The first through hole 1 is directly connected to the cavity 7 formed by the pool body. The first through hole 1 and the second through hole 2 are used to install the first flange sleeve 3.

[0034] Step 2, Pipe Preparation: Obtain the first flange sleeve 3. The first end of the first flange sleeve 3 passes through the first through hole 1 and extends into the cavity 7. The second end is provided with a first sealing flange 31 and extends to the outside of the second through hole 2. The cavity formed by the second through hole 2 is filled and sealed with filling material 6. At this time, a part of the first flange sleeve 3 extends into the cavity 7 and communicates with the cavity 7. The other part of the first flange sleeve 31 placed in the second through hole 2 is filled with filling material 6, which can fix the first flange sleeve 3 on the one hand, and greatly enhance the sealing performance on the other hand, so that the gap between the first flange sleeve 3 and the wall is sealed and there will be no leakage.

[0035] Step 3, Piping: Obtain the hose 5. The first end of the hose 5 extends into the cavity through the first flange sleeve 3, and the second end is sleeved on the second flange sleeve 4. The second sealing flange 41 of the second flange sleeve 4 is connected to the first sealing flange 31 to form a unique sealing port. When it is necessary to seal the sealing port, simply tighten and fix the external end cap to any sealing flange to form a tight seal. When it is necessary to extract the material in the pool, connect any sealing flange to the working port of the suction pump 8 to extract the material in the pool.

[0036] In this solution, although there will still be a certain gap between the first through hole 1 and the first flange sleeve 3, the second through hole 2 can be filled and sealed by the filling material 6, without the need for personnel to enter the pool to perform the sealing operation; furthermore, while the cavity 7 is connected by the hose 5, it can be quickly closed and used through the sealing port formed by the first sealing flange 31 and the second sealing flange 41.

[0037] To further enhance the assembly stability and sealing performance of the first flange sleeve 3, in this embodiment, an assembly hole is also provided on the inner end face of the second through hole 2 during the hole-opening step; during the pre-pipe laying step, the pipe body of the first flange sleeve 3 is also provided with an assembly flange 32, which is fixedly connected to the assembly hole; it is easy to understand that the assembly flange protrudes from the cylindrical surface of the first flange sleeve 3 and is fixedly fitted to the outer end face of the first through hole 1. The fixing method can be achieved by using expansion bolts, which further increases the sealing density of the first flange sleeve 31 to the first through hole; during the further sealing process using filling material 6, the assembly flange 32 increases the contact area, which further enhances the stability and sealing performance of the first flange sleeve 3.

[0038] To further enhance the stability of the connection between the flexible hose 5 and the second flange sleeve 4, in this embodiment, during the pipe laying step, a clamp 51 is also fitted onto the connection portion between the flexible hose 5 and the second flange sleeve 4; tightening the clamp 51 further enhances the stability of the connection between the second flange sleeve 4 and the flexible hose 5.

[0039] In a better solution, during the pipe laying step, the type of hose 5 is a steel wire hose; the steel wire hose type hose 5 has better working stability, and after the first end of the hose 5 enters the cavity 7, it can hang down by its own weight and come into contact with the material in the pool, which is convenient for subsequent suction treatment using a suction pump 8.

[0040] In this embodiment, a sealing gasket is provided between the first sealing flange 31 and the second sealing flange 41 during the pipe laying step. The sealing gasket can further enhance the sealing performance between the first sealing flange 31 and the second sealing flange 41. Naturally, during the assembly of the suction pump 8, the sealing gasket can be used to further enhance the connection between the suction pump 8 and the sealing port.

[0041] In this embodiment, before the hole-opening step, the liquid level of the substance in the cavity 7 is below the liquid level line overlapping the axis of the first through hole 1; if the liquid level of the substance in the cavity 7 is higher than the axis of the first through hole, the substance in the pool will leak out during the hole-opening process.

[0042] In this embodiment, during the pre-pipe laying step, the filling material is one or more of cement or sealing putty; cement is preferred because it is inexpensive and has good sealing properties.

[0043] The advantages of this invention are:

[0044] 1) The above method can be completed by staff outside the pool without entering the pool, and greatly increases the sealing and prevents the leakage of substances inside the pool.

[0045] 2) The assembly flange protrudes from the cylindrical surface of the first flange sleeve and is fixedly fitted to the outer end face of the first through hole, further increasing the sealing density of the first flange sleeve to the first through hole; during the sealing process using filling material, the assembly flange increases the contact area, which further increases the stability and sealing performance of the first flange sleeve.

[0046] The above-disclosed embodiments are merely a few specific examples of the present invention, but the present invention is not limited thereto. Any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
