[0002] The closed water test is an important method for the acceptance of municipal sewage pipes, and it is also a test item required by the specifications. If there is a water leakage problem in the sewage pipe, it will cause sewage to seep into the groundwater and cause groundwater pollution. For the closed water test of the non-pressure pipe, if conditions permit, no more than 5 consecutive well sections can be tested at a time; when the inner diameter of the pipe is greater than 700mm, 1 / 3 of the well sections can be sampled for testing. If the test fails, the number of sampled well sections should be doubled on the basis of the original sampling. The closed water test is separated by well spacing and sampled. It needs to be tested simultaneously with the inspection well, so the end of the pipe needs to be closed.

[0003] The existing sealing methods are brick wall sealing or rubber air bag sealing; brick wall sealing requires waiting for the mortar strength to reach 100% before testing, and the waiting time is relatively long; rubber air bag is prone to leakage and has a low turnover rate. In case of leakage, it is necessary to re-inject water and soak for no less than 24 hours before observing the seepage volume; trench backfilling work is allowed only after the water-tightness test is passed, which causes the foundation pit and pipeline to be exposed for too long, affecting the stability of the foundation pit.

In addition, those skilled in the art may combine and combine the different embodiments or examples described in this specification and the features of the different embodiments or examples, without contradiction.

[0049] Combine the following Figures 1 to 8 It should be understood that the following description is only an illustrative embodiment of the present invention and does not constitute a limitation on the present invention.

[0050] like Figure 1 As shown, the present invention provides a pipeline plugging tool, comprising: a rubber sealing panel 100, a plugging rod 200, a slider 103 sleeved on the plugging rod 200, and a folding frame 110 for changing the state of the rubber sealing panel 100.

[0051] One end of the folding frame 110 is hinged on the rubber sealing panel 100 , and the other end is installed on the slider 103 .

[0052] Furthermore, the rubber sealing panel 100 includes a blocking surface 101 and a sealing surface 102 .

[0053] In the blocked state, the blocking surface 101 is spread out in the radial direction of the pipe 300 , and the sealing surface 102 is spread out in the axial direction of the pipe 300 .

[0054] In one embodiment of the present invention, the sealing surface 102 is disposed in a columnar shape on the outer edge of the blocking surface 101 , and the blocking surface 101 and the sealing surface 102 are integrally formed.

[0055] In other words, the blocking surface 101 and the sealing surface 102 are integrally injection molded.

[0056] like Figure 2 As shown, in one embodiment of the present invention, the diameter of the blocking surface 101 is equal to the inner diameter of the pipe 300 , and the sealing surface 102 is attached to the inner wall of the pipe 300 .

[0057] By unfolding the blocking surface 101, the sealing surface 102 is driven to fit closely on the inner wall of the pipe 300. Since the rubber material has good plastic deformation, a better sealing effect is achieved during the extrusion process.

[0058] Continue to refer Figure 1 In another embodiment of the present invention, one end of the folding skeleton is evenly distributed on the slider 103 , and the other end is evenly distributed on the blocking surface 101 and the sealing surface 102 .

[0059] The uniform distribution on the slider 103 in this embodiment may be uniform distribution along the axial direction of the slider 103 , may be uniform distribution along the radial direction of the slider 103 , or may even be uniform distribution along both the axial direction and the radial direction of the slider 103 .

[0060] Further, continue to refer to Figure 1 In one embodiment of the present invention, the folding frame 110 includes a folding rod group and a hinge group.

[0061] The folding rod group includes at least one folding inflection point, and the hinge group is installed on the inner surface of the rubber closing panel 100 for hingedly connecting the folding rod group.

[0062] refer to Figure 1 , Figure 3 and Figure 4 In an optional embodiment of the present invention, the hinge assembly includes a flat hinge 112 and a bent hinge 111, the flat hinge 112 is installed on the blocking surface 101 and the sealing surface 102, and the bent hinge 111 is installed at the intersection of the blocking surface 101 and the sealing surface 102.

[0063] Continue to refer Figure 4 With respect to the flat hinge 112 , in the embodiment of the present invention, the flat hinge 112 includes a first mounting surface 113 and a first hinge point 114 on the first mounting surface 113 .

[0064] The first mounting surface 113 is mounted on the flat area of ​​the blocking surface 101 and the sealing surface 102. The flat area specifically refers to the surface state displayed in the blocking state. In other words, except for the intersection of the blocking surface 101 and the sealing surface 102, the other parts are all flat areas.

[0065] The first hinge point 114 is used to hinge the folding rod assembly.

[0066] For the bent hinge 111, refer to Figure 3 and Figure 5 In an embodiment of the present invention, the bent hinge 111 includes a second mounting surface 115 and a third mounting surface 116 , the second mounting surface 115 has a second hinge point 118 at its end, and the third mounting surface 116 has a third hinge point 117 at its end.

[0067] The second mounting surface 115 is mounted on the blocking surface 101 , and the third mounting surface 116 is mounted on the sealing surface 102 ; the second hinge point 118 , the third hinge point 117 and the folding rod group are hinged together.

[0068] Of course, the second mounting surface 115 of the bent hinge 111 can also be installed on the sealing surface 102 , and the third mounting surface 116 can also be installed on the blocking surface 101 . Similarly, the folding rod group is still hinged to the second hinge point 118 and the third hinge point 117 .

[0069] like Figure 6 As shown, in an optional embodiment of the present invention, the folding rod group includes multiple groups of first folding rods 121 and second folding rods 122, and the first folding rods 121 and the second folding rods 122 are hinged together. One end of the first folding rod 121 and the second folding rod 122 are both provided with holes for easy installation with the hinge group and the slider.

[0070] In this embodiment, the first folding rod 121 is hinged to the hinge assembly, and the second folding rod 122 is installed to the slider 103 .

[0071] Among them, Figure 7 As shown, in order to achieve a better folding effect, a hinge seat 120 is provided on the slider 103, and the second folding rod 122 is hinged on the hinge seat 120 of the slider 103 to achieve the necessary rotation for folding.

[0072] Continue to refer Figure 1 , Figure 2 and Figure 7 In one embodiment of the present invention, a limiting hole 201 is opened on the blocking rod 200, and the limiting hole 201 is used to insert a limiting pin 202.

[0073] Furthermore, when using the pipeline plugging tool of the present application, the rubber sealing panel 100 of appropriate size is rotated, and the folding frame 110 is installed through the hinge assembly. The folding frame 110 is installed on the slider 103, and the slider 103 is sleeved on the plugging rod 200.

[0074] The slider 103 on the blocking rod 200 is pushed through the folding frame 100 to drive the rubber sealing panel 100 to unfold. In the unfolded state, the blocking surface 101 is perpendicular to the sealing surface 102, and the sealing surface 102 is tightly fitted with the inner wall of the pipe 300 to achieve sealing. After the rubber sealing panel 100 is unfolded, the limit pin 202 is inserted into the limit hole 201 to prevent the slider 103 from sliding down.

[0075] After the blocking is completed, the limiting pin 202 in the limiting hole 201 is pulled out, and the slider 103 is slid down, thereby driving the folding frame 110 to fold the rubber sealing panel 100 for storage.

[0076] It should be emphasized that the blocking rod 200 is in contact with the rubber sealing panel 100 .

[0077] The pipe plugging tool provided by the present invention drives the folding bracket by pushing the slider on the plugging rod, thereby driving the expansion and folding of the rubber sealing panel to achieve the plugging of the pipe. The structure of the present application is simple, and it is easy to replace rubber sealing panels of different sizes, which improves the turnover rate and has stronger applicability.

[0078] like Figure 8 As shown, the present invention also provides a method for using a pipeline plugging tool, the steps comprising:

[0079] S1: Determine the blocking position;

[0080] S2: Clean the inside of the pipeline plugging port;

[0081] S3: Select a rubber closure panel of appropriate diameter;

[0082] S4: assembling pipeline plugging tools;

[0083] S5: placing the folded pipeline plugging tool into the pipeline plugging opening;

[0084] S6: Push the slider to unfold the rubber closure panel;

[0085] S7: Limit the movement of the slider.

[0086] This method of use achieves rapid sealing of pipelines, shortens test time, reduces exposure time of foundation pits and pipelines, and reduces safety hazards; the rubber sealing panel has strong durability, high turnover, simple maintenance, convenient disassembly and replacement, and high economic benefits; it improves the tightness of sealing and reduces construction costs.

[0087] In one embodiment of the present invention, after the pipeline plugging tool is assembled in step S4, the pipeline plugging tool may be tested to verify the overall effect of the pipeline plugging tool.

[0088] Furthermore, in another embodiment of the present invention, step S7 limits the movement of the slider, which may be specifically achieved by inserting a limit pin into a limit hole on the sealing rod of the pipeline sealing tool to limit the movement of the slider.

[0089] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present invention.
