Technical Field

[0001] The present application relates to the technical field of sewage treatment, and in particular to a sewage treatment tank casing plugging module, a sewage treatment tank, and a method for plugging a gap in a sewage treatment tank casing. Background Art

[0002] In sewage treatment projects, water holes are set on the wall of the sewage treatment pool, and sleeves and water pipes are set in the water holes. The sleeves are put on the water pipes. In order to prevent sewage from leaking from the gap between the sleeves and the water pipes, the gap between the sleeves and the water pipes is generally sealed. The current sealing process is usually to insert hemp into the gap, and then seal the ports at both ends of the water hole with sealing paste and other materials. However, this process method mainly considers the density of the hemp filling in the gap. Once the density of the hemp filling is not enough, or the gap between the pipe and the sleeve is uneven, the hemp cannot be dense, and it will inevitably cause leakage risks.

[0053] like Figure 1 and Figure 2 As shown, one aspect of the present application provides a sewage treatment pool casing plugging module, including a sewage pool wall 03, a casing 08 and a water pipe 06, wherein a through hole is formed on the sewage pool wall 03, the casing 08 and the water pipe 06 are both inserted into the through hole, and the casing 08 is sleeved on the water pipe 06; the sewage treatment pool casing plugging module also includes a dry hemp circle 07 and a polyurethane grouting material layer 02, both of which are located in the through hole, the dry hemp circle 07 is located between the casing 08 and the water pipe 06, the dry hemp circle 07 is sleeved on the water pipe 06, and the polyurethane grouting material layer 02 is used to fill the gap between the casing 08 and the water pipe 06.

[0054] The sewage treatment pool casing plugging module provided by the present application has a polyurethane grouting layer 02 that fills the gap between the casing 08 and the water pipe 06. The polyurethane grouting layer 02 is injected into the gap between the casing 08 and the water pipe 06 in a liquid state, and will expand dozens of times during the curing process, and will inevitably fill the gap between the casing 08 and the water pipe 06, so that the gap between the casing 08 and the water pipe 06 is difficult to leak, thereby reducing the hidden danger of water leakage; at the same time, a dry hemp circle 07 is provided so that the polyurethane grouting layer 02 can enter the dry hemp circle 07 itself and wrap the dry hemp circle 07, so that the dry hemp circle 07 becomes the internal skeleton of the polyurethane grouting layer 02, thereby making the overall strength formed by the dry hemp circle 07 and the polyurethane grouting layer 02 greater, and is not easy to break under the pressure of water, thereby improving the reliability of the seal and further reducing the hidden danger of water leakage.

[0055] In the embodiment of the present application, the polyurethane grouting material layer 02 can be made of polyurethane grouting material that meets the requirements, preferably, it is made of polyurethane grouting material produced by Hengjian Bojing Waterproof Material Co., Ltd. In the embodiment of the present application, the gap between the casing 08 and the water pipe 06 is expanded and compacted after the grouting and curing of the polyurethane grouting, and has a certain strength and flexibility, so as to prevent the liquid in the pool from penetrating and flowing out through the gap between the casing 08 and the water pipe 06.

[0056] Optionally, the sewage treatment pool casing plugging module provided in the embodiment of the present application includes a plurality of dry hemp rings 07, and each of the dry hemp rings 07 is evenly distributed in the axial direction of the water pipe 06. This allows the dry hemp rings 07 to be arranged at multiple positions between the casing 08 and the water pipe 06 in the through hole, further improving the overall strength formed by the dry hemp and the polyurethane grouting material layer 02, and further reducing the potential for water leakage. In the embodiment of the present application, the number of the dry hemp rings 07 is preferably 2 to 9, for example, it can be 3, 5, 7, etc. In the embodiment of the present application, the number of the dry hemp rings 07 is preferably 5.

In the embodiment of the present application, the anti-crack waterproof layer can be made of anti-crack waterproof materials that meet the requirements, preferably, it is made of products called "anti-crack water-proof" on the market. In this way, the pressure of the sewage in the sewage pool is first borne by the anti-crack waterproof layer, so that the sewage is not easy to act on the polyurethane grouting material layer 02 and the dry hemp between the casing 08 and the water pipe 06, further reducing the hidden danger of water leakage.

[0058] Optionally, the hemp circle 07 includes a plurality of hemp strands, and gaps for passing through the slurry are formed between adjacent hemp strands in the hemp circle 07. That is, the hemp circle 07 is a fluffy hemp bundle formed by a plurality of hemp strands, so that the anti-cracking and waterproof material injected into the gap between the sleeve 08 and the water pipe 06 can pass smoothly, making it easier for the anti-cracking and waterproof material to fill the gap between the sleeve 08 and the water pipe 06.

[0059] Another aspect of the present application provides a sewage treatment tank, which also includes at least one sewage treatment tank casing plugging module provided by an embodiment of the present application.

[0060] The sewage treatment pool provided in the present application adopts the sewage treatment pool casing plugging module provided in the present application. Since the polyurethane grouting layer 02 fills the gap between the casing 08 and the water pipe 06, the polyurethane grouting layer 02 is injected into the gap between the casing 08 and the water pipe 06 in a liquid state, and will expand dozens of times during the curing process, and will inevitably fill the gap between the casing 08 and the water pipe 06, so that the gap between the casing 08 and the water pipe 06 is difficult to leak, thereby reducing the hidden danger of water leakage; at the same time, a dry hemp circle 07 is provided so that the polyurethane grouting layer 02 can enter the dry hemp circle 07 itself and wrap the dry hemp circle 07, so that the dry hemp circle 07 becomes the internal skeleton of the polyurethane grouting layer 02, thereby making the overall strength formed by the dry hemp circle 07 and the polyurethane grouting layer 02 greater, and it is not easy to break under the pressure of water, thereby improving the reliability of the seal and further reducing the hidden danger of water leakage.

[0064] The method for sealing the gap inside the casing of a sewage treatment pool provided in the present application has the following characteristics: since the polyurethane grouting layer 02 fills the gap between the casing 08 and the water pipe 06, the polyurethane grouting layer 02 is injected into the gap between the casing 08 and the water pipe 06 in a liquid state, and expands dozens of times during the curing process, and will inevitably fill the gap between the casing 08 and the water pipe 06, so that the gap between the casing 08 and the water pipe 06 is difficult to leak, thereby reducing the hidden danger of water leakage; at the same time, a dry hemp circle 07 is provided so that the polyurethane grouting layer 02 can enter the dry hemp circle 07 itself and wrap the dry hemp circle 07, so that the dry hemp circle 07 becomes the internal skeleton of the polyurethane grouting layer 02, thereby making the overall strength formed by the dry hemp circle 07 and the polyurethane grouting layer 02 greater, and it is not easy to break under the pressure of water, thereby improving the reliability of the seal and further reducing the hidden danger of water leakage.

[0065] Optionally, before step 100, the following steps are included:

[0066] Step 300: removing the material used to cover the gap between the sleeve 08 and the water pipe 06 at the end of the through hole from the outside of the sewage treatment tank, and taking out the oil hemp in the gap between the sleeve 08 and the water pipe 06;

[0070] The polyurethane grouting material is filled into the gap between the sleeve 08 and the water pipe 06 from the outside of the sewage treatment tank to form the polyurethane grouting material layer 02 .

[0071] In this way, when a small amount of water leakage occurs in the gap between the casing 08 and the water pipe 06 that was originally sealed with hemp, the sealing method can also be performed outside the sewage treatment tank without draining all the water in the sewage treatment tank.

[0072] When serious leakage occurs in the gap between the casing 08 and the water pipe 06 of the sewage treatment tank, water withdrawal treatment is performed. When the water in the tank is completely withdrawn and the conditions for internal and external sealing are met, the method for sealing the gap in the casing of the sewage treatment tank provided in the embodiment of the present application is implemented.
