Abstract
Description
Technical Field
[0001] The present application relates to the technical field of pipeline laying, and in particular to a pipeline settlement protection connection structure. Background Art
[0002] In construction projects, it is common practice to run pipes from inside a building and extend them on the ground outdoors. This approach is simple to construct and has low cost.
[0003] However, as the building ages, common problems arise: indoor floors with structural foundations hardly settle, while outdoor floors without structural foundations continue to settle. Pipes are subjected to uneven stretching at the indoor and outdoor joints, causing the outdoor parts of the pipes to break easily, which may cause serious water leakage problems, resulting in inconvenience in building use and safety risks. Utility Model Content
[0004] In order to reduce the risk of pipeline damage due to ground subsidence, the present application provides a pipeline subsidence protection connection structure.
[0005] The present application provides a pipeline settlement protection connection structure, which adopts the following technical solutions:
[0006] A pipeline settlement protection connection structure includes a first pipeline arranged indoors, a second pipeline arranged on the outdoor ground, and a connection structure for connecting the first pipeline and the second pipeline, wherein the connection structure can be deformed with the relative movement of the second pipeline and the first pipeline.
[0007] By adopting the above technical solution, a connecting structure that can deform with the relative movement of the pipeline is provided, so as to achieve a flexible connection between indoor and outdoor pipelines. When the pipeline sinks or moves due to various reasons, the connecting structure can absorb these deformations to avoid pipeline rupture or breakage of the connection, thereby protecting the integrity and safety of the pipeline system.
[0008] Optionally, the connection structure includes a first connection pipe connected to the lower end of the first pipe, and a second connection pipe connected to the upper end of the second pipe, and the first connection pipe can be inserted into the first connection pipe.
[0009] By adopting the above technical solution, when the first pipeline and the second pipeline move relatively, the relative position between the first connecting pipe and the second connecting pipe can be adjusted, thereby maintaining the connection state of the pipeline system.
[0010] Optionally, a sealing ring is provided between the outer wall of the first connecting tube and the inner wall of the second connecting tube.
[0011] By adopting the above technical solution, a sealing ring is provided between the first connecting pipe and the second connecting pipe, thereby ensuring the sealing of the pipe connection, which can effectively prevent liquid from leaking from the connection and improve the safety and reliability of the pipe system.
[0012] Optionally, a convex ring is circumferentially arranged on the outer side wall of the sealing ring, and a plurality of the convex rings are arranged at intervals along the vertical direction.
[0013] By adopting the above technical solution, a convex ring is arranged on the outer side wall of the sealing ring, and multiple convex rings are arranged at intervals in the vertical direction, which enhances the friction between the sealing ring and the pipeline and makes the connection more secure; at the same time, the setting of the convex ring also increases the sealing performance of the sealing ring and further prevents leakage.
[0014] Optionally, the connection structure further includes a clamp sleeved on the outside of the second connecting pipe.
[0015] By adopting the above technical solution, a clamp is added to the connection structure to fix the second connecting pipe, thereby improving the stability of the pipeline connection; at the same time, the clamp structure is connected by friction. After the outdoor ground settles, the second connecting pipe can move downward under the action of gravity, and the clamp can still perform the connecting function.
[0016] Optionally, the connecting structure includes a third connecting tube connected to the lower end of the first pipe, a fourth connecting tube connected to the upper end of the second pipe, and a fifth connecting tube connected between the third connecting tube and the fourth connecting tube, and the tube body of the fifth connecting tube is elastic.
[0017] By adopting the above technical solution, the third connecting pipe and the fourth connecting pipe are connected by an elastic fifth connecting pipe, and this design makes the connection structure have better elasticity and deformation capacity. When the pipeline sinks or moves horizontally, the fifth connecting pipe can undergo corresponding elastic deformation, thereby effectively absorbing these deformations and protecting the integrity and safety of the pipeline system.
[0018] Optionally, the third connecting pipe and the fifth connecting pipe, as well as the fifth connecting pipe and the fourth connecting pipe are connected via flanges.
[0019] By adopting the above technical solution, the third connecting pipe, the fifth connecting pipe and the fourth connecting pipe are connected by the flange, so that the pipeline connection is more convenient and reliable. The flange connection has the advantages of simple structure, convenient installation and easy disassembly, and can also withstand certain pressure and tension, ensuring the stability and safety of the pipeline system.
[0020] Optionally, the lower end of the third connecting tube is inserted into the fifth connecting tube, and the lower end of the fifth connecting tube is inserted into the fourth connecting tube.
[0021] By adopting the above technical solution, the lower end of the third connecting tube is inserted into the fifth connecting tube, and the lower end of the fifth connecting tube is inserted into the fourth connecting tube. This design further enhances the sealing of the connection.
[0022] The connection structure (3) further comprises a limiting screw (37) and a limiting nut (38); the limiting screw (37) can pass through all the flanges (5) in sequence and be connected to the limiting nut (38); when the fifth connection tube (36) is deformed to abut against the limiting nut (38), the limiting nut (38) can limit the fifth connection tube (36) from further deformation.
[0023] By adopting the above technical solution, when the fifth connecting pipe is deformed to a certain extent, the cooperation of the limit screw and the limit nut can limit the further deformation of the fifth connecting pipe, thereby avoiding the fifth connecting pipe from being excessively deformed and ruptured; at the same time, by observing the relative length of the limit screw and the flange, the degree of ground subsidence can be judged.
[0024] In summary, the present application includes at least one of the following beneficial effects:
[0025] 1. By adopting the plug-in cooperation of the first connecting pipe and the second connecting pipe, the pipeline system can flexibly adapt to the settlement deformation, avoiding the occurrence of pipeline rupture or connection breakage;
[0026] 2. By providing a fifth connecting pipe that can be elastically deformed, the pipeline connection system can not only be relatively deformed during vertical settlement, but also relatively deformed and adapted during relative horizontal displacement. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0033] The following is combined with Figure 1-5 This application is described in further detail.
[0034] Example 1
[0035] The present application embodiment discloses a pipeline subsidence protection connection structure. Figure 1 The pipeline settlement protection connection structure includes a first pipeline 1, a second pipeline 2 and a connection structure 3, wherein the first pipeline 1 is installed on the inner wall of the building, the second pipeline 2 is laid on the outdoor ground, and the connection structure 3 is used to connect the first pipeline 1 and the second pipeline 2. When the outdoor ground settles, causing the second pipeline 2 to move downward, the connection component can be relatively deformed accordingly, so that the connection between the first pipeline 1 and the second pipeline 2 will not break.
[0036] Reference Figure 1 and Figure 2 Specifically, in this embodiment, the connecting member includes a first connecting tube 31 connected to the lower end of the first pipeline 1, and a second connecting tube 32 connected to the upper end of the second pipeline 2. The lower end of the first connecting tube 31 can be inserted into the second connecting tube 32, so that the connection and positioning can be performed; at the same time, under this matching mode, the liquid flows into the second connecting tube 32 along the first connecting tube 31. In order to enhance the strength of the pipeline, the first tube body and the first connecting tube 31, and the second tube body and the second connecting tube 32 can be integrally formed.
[0037] Reference Figure 1 and Figure 2 In order to improve the sealing of the connection, a sealing ring 4 is provided between the outer wall of the first connecting tube 31 and the inner wall of the second connecting tube 32. The sealing ring 4 can be made of rubber or other soft sealing materials. When in use, the sealing ring 4 is first sleeved on the outer side of the first connecting tube 31, and then the first connecting tube 31 is inserted into the second connecting tube 32. Preferably, the first connecting tube 31 is inserted into the second connecting tube 32 by 200-300 mm, so that the sealing ring 4 fits tightly between the two connecting tubes, effectively preventing liquid or gas from leaking through the connection.
[0038] Furthermore, in order to further enhance the sealing effect, a convex ring 41 is circumferentially arranged on the outer wall of the sealing ring 4. The cross section of the convex ring 41 is semicircular, and a plurality of convex rings 41 are arranged at intervals along the vertical direction. These convex rings 41 are deformed when the sealing ring 4 is squeezed, and can be pressed against the inner wall of the second connecting pipe 32 to form a multiple sealing barrier, which greatly improves the sealing performance of the connection.
[0039] Reference Figure 1 and Figure 2 In this embodiment, the connection structure 3 further includes a hoop 33 sleeved on the outer wall of the second connection pipe 32, and the hoop 33 includes a first half ring 331, a second half ring 332, a first bolt 333 and a first nut 334. When in use, the first connection pipe 31 is first inserted into the second connection pipe 32, and then the first half ring 331 and the second plate are sleeved against the outer wall of the second connection pipe 32, and then the first bolt 333 is sequentially passed through the first half ring 331 and the second half ring 332, and the first nut 334 is used to lock the first connection pipe 31 and the second connection pipe 32. The first bolt 333 and the first nut 334 are provided at both ends of the first half ring 331 and the second half ring 332, so that the first connection pipe 31 and the second connection pipe 32 can be locked, and the connection strength can be ensured, and the internal sealing ring 4 can be squeezed by pressure to ensure the waterproof effect. Preferably, a plurality of hoop 33 can be arranged at intervals along the length direction of the second connection pipe 32.
[0040] A clamp 33 is provided to improve the stability of the connection by means of friction. At the same time, when the ground settles, when water flows from the first pipe 1 along the first connecting pipe 31 and the second connecting pipe 32 into the second pipe 2, under the action of impact force and gravity, the second pipe 2 and the second connecting pipe 32 can move downward and re-connect with the ground.
[0041] The implementation principle of a pipeline settlement protection connection structure in an embodiment of the present application is as follows: when the outdoor ground settles, the second pipe body and the first connecting pipe 31 will be displaced downward. At this time, since the first connecting pipe 31 is inserted into the second connecting pipe 32, they are relatively unique in time and can still be in a mutually plugged state, and will not affect the connection. That is, this connection method enables the pipeline to adapt to a certain degree of ground settlement.
[0042] Example 2
[0043] The difference between this embodiment and embodiment 1 is that the connection structure 3 is different. Figure 3In this embodiment, the connecting structure 3 includes a third connecting pipe 34 connected to the lower end of the first pipe, a fourth connecting pipe 35 connected to the upper end of the second pipe 2, and a fifth connecting pipe 36 connected between the third pipe and the fourth pipe. The third connecting pipe 34 and the fifth connecting pipe 36, and the fifth connecting pipe 36 and the fourth connecting pipe 35 are connected through a flange 5, wherein the fifth connecting pipe 36 is elastic and is preferably a corrugated pipe, or a rubber pipe.
[0044] Reference Figure 3 and Figure 4 Specifically, the flange 5 is composed of two disc bodies 51, a second bolt 52, and a second nut 53. The disc body 51 is fixed on the outer wall of the third connecting tube 34, and the disc body 51 is fixed on the outer wall of the upper end of the fifth connecting tube 36. When in use, the third connecting tube 34 can be inserted into the fifth connecting tube 36. At this time, the two disc bodies 51 abut against each other and are fixed by the second bolt 52 and the second nut 53, so as to connect the third connecting tube 34 and the fifth connecting tube 36. At the same time, a sealing gasket 6 can be further provided between the two disc bodies 51 to improve the sealing of the connection; similarly, the lower end of the fifth connecting tube 36 can be inserted into the fourth connecting tube 35, and the outer wall of the fifth connecting tube 36 and the outer wall of the upper end of the fourth connecting tube 35 are respectively provided with disc bodies 51 for connection.
[0045] Reference Figure 5 Furthermore, in another optional embodiment, the connecting structure 3 may also include a limiting screw 37 and a limiting nut 38. The limiting screw 37 is sequentially passed through all the flanges 5 in the vertical direction and is threadedly connected with the limiting nut 38. At this time, a certain distance is set between the head of the limiting screw 37 and the lower surface of the disk body 51 located on the fourth connecting tube 35. When the limiting screw 37 is passed from top to bottom, a certain distance is set between the limiting nut 38 and the lower surface of the disk body 51. As the ground settles, the fifth connecting tube 36 continues to grow in length, and the position of the disk body 51 on the fourth connecting tube 35 gradually moves downward relatively. When the disk body 51 abuts against the head of the limiting screw 37, the fifth connecting tube 36 is restricted from further extending. Therefore, by setting the limiting screw 37 and the limiting nut 38, the fifth connecting tube 36 can be prevented from being excessively deformed and damaged, resulting in liquid exposure. At the same time, the distance of ground sinking can be judged by observing the distance between the disk body 51 and the head of the limiting screw 37; when the head of the limiting screw 37 is in contact with the disk body 51, or is close enough, the service life of the connection structure can be ensured by replacing the fifth connecting pipe 36.
[0046] In this embodiment, by adding the fifth connecting tube 36 for a detachable connection, the connection can be easily repaired; at the same time, since the fifth connecting tube 36 is elastic, when a vertical relative displacement or a lateral relative displacement occurs between the first pipe 1 and the second pipe 2, the fifth connecting tube 36 can be deformed accordingly to ensure that the connection is not damaged; and a limiting screw 37 and a limiting nut 38 can be further added to prevent the fifth connecting tube 36 from excessive deformation and damage.
[0047] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
