Description

Technical Field

[0001] The utility model relates to the field of reinforced concrete pipelines, in particular to a silt leakage prevention structure for a socket-and-spigot interface of a reinforced concrete pipeline. Background Art

[0002] At present, the conventional construction method of reinforced concrete pipe socket joints is to use rubber rings and cement mortar to hold the peak joints. The construction quality of the joints is difficult to control. It often needs to be reworked many times because of leakage problems in the pipe joints during the closed water test and the phenomenon of leakage of mud and sand as the service time increases. How to improve the quality of pipe joints is an important issue faced in construction.

[0003] According to the published patent 202121335511.0, a building water supply and drainage leakage prevention component includes a connecting mechanism; the connecting mechanism is the leakage prevention component body, and an installation mechanism is installed on the right side of the connecting mechanism; a sealing mechanism is installed inside the connecting mechanism, and there are two groups of sealing mechanisms; a cleaning mechanism is installed at the bottom end of the connecting mechanism, and a guide rod is installed between the sealing parts; the cleaning part is installed on the right side of the guide rod through a spring. When in use, the water impact force passes through the mounting piece and the guide of the guide piece, so that the water impacts the rectangular block on the cleaning piece, thereby driving the cleaning piece to compress the spring on the guide rod while guiding it to move on the guide rod, thereby scraping off the mud and sand at the bottom. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although a sealing piece and a mounting piece are provided, the mounting piece here is installed on the right side of the main body, and the sealing piece is installed inside the main body. When in use, the embedded piece on the mounting piece is inserted into the embedded groove. At this time, the main body squeezes the embedded piece on the mounting piece, so that the plug-in is inserted into the main body. At the same time, after the plug-in moves to a suitable position, the embedded piece is reset and then installed in the embedded groove. The positioning piece is inserted into the threaded hole on the outer ring, and then the main body and the mounting piece are installed together. However, during use, the traditional reinforced concrete pipe is connected by a sealing piece and a plug-in to seal the socket interface of the reinforced concrete pipe. This sealing method, due to the use of plug-in, will still cause mud and sand leakage as the position of the socket interface loosens. Therefore, it is necessary to design a new technical solution. Utility Model Content

[0004] The purpose of the utility model is to overcome the shortcomings of the prior art, meet the actual needs, and provide a reinforced concrete pipe socket interface mud and sand leakage prevention structure to solve the current traditional reinforced concrete pipe, which adopts seals and plug-ins to seal the socket interface of the reinforced concrete pipe. This sealing method, due to the use of plug-in connection, will still cause mud and sand leakage as the position of the socket interface loosens.

[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: designing a reinforced concrete pipe socket interface sediment leakage prevention structure, including a first reinforced concrete pipe and a second reinforced concrete pipe, and also including:

[0006] An annular sealing shell is sleeved between the first reinforced concrete pipe and the second reinforced concrete pipe;

[0007] A sediment anti-leakage mechanism is installed at the upper and lower ends of the annular sealing shell, wherein the sediment anti-leakage mechanism comprises an arc-shaped net shell, and the arc-shaped net shell is filled with mineral fillers;

[0008] An arc-shaped support plate is fixed at one end of the arc-shaped net shell, and a water-swellable waterproofing cotton is fixed at one end of the arc-shaped support plate away from the arc-shaped net shell.

[0009] Preferably, a first connecting tube is fixed to one end of the arc-shaped lattice shell away from the arc-shaped supporting plate body, and the other end of the first connecting tube extends deep into the second connecting tube.

[0010] Preferably, a connecting plate is fixed to one end of the first connecting tube located in the second fixing tube, and a spring is fixed to one end of the connecting plate away from the first fixing tube.

[0011] Preferably, an inner tube body is fixed to one side of the first reinforced concrete pipe and the second reinforced concrete pipe, and the two inner tube bodies fit each other.

[0012] Preferably, a plurality of circular holes are formed on one side of the first reinforced concrete pipe and the second reinforced concrete pipe, and support rods are fixed inside the plurality of circular holes.

[0013] Preferably, connecting strips are fixed to the upper and lower ends of both sides of the annular sealing shell, a plurality of fixing bolts penetrate the connecting strips, and the plurality of fixing bolts are threadedly connected to the thread grooves on the surfaces of the first reinforced concrete pipe and the second reinforced concrete pipe.

[0014] Compared with the prior art, the beneficial effects of the present invention are:

[0015] 1. The utility model combines an arc-shaped mesh shell, a mineral filler and a water-swellable waterproofing cotton. After the two reinforced concrete pipes are inserted into the annular sealing shell, the elastic force of the spring will drive the arc-shaped support plates at the upper and lower positions to clamp the positions of the interfaces of the two reinforced concrete pipes, thereby sealing the positions of the interfaces. Since the water-swellable waterproofing cotton is arranged on the surface of the arc-shaped support plate, when mud and sand leakage occurs at the interface of the reinforced concrete pipe, the water in the mud and sand will contact the water-swellable waterproofing cotton, and the water-swellable waterproofing cotton will expand rapidly, thereby actively squeezing and covering the position of the interface, thereby improving the anti-leakage effect. Moreover, a mineral filler is arranged inside the arc-shaped mesh shell, and the arc-shaped mesh shell and the mineral filler can block the mud and sand to prevent it from leaking out. This solves the problem that the traditional reinforced concrete pipe adopts a seal and a plug-in connection to seal the socket interface of the reinforced concrete pipe. Due to the use of plug-in, this sealing method still has the technical problem of mud and sand leakage as the socket interface position becomes loose.

[0016] 2. The utility model combines a reinforced concrete pipe, an inner pipe body and a support rod body. Since the inner pipe body is arranged inside the reinforced concrete pipe, the reinforced concrete pipes can be butted through the inner pipe body during the butt-jointing installation. Moreover, the support rod body is used to pass through two reinforced concrete pipes at the same time, so the connection position of the two reinforced concrete pipes can be limited and fixed, and cooperated with the external limit connection strip to achieve internal and external double limit fixation, thereby avoiding the loosening of the butt joint position of the two reinforced concrete pipes and causing leakage of mud and sand.

DETAILED DESCRIPTION

[0021] The utility model is further described below in conjunction with the accompanying drawings and embodiments:

[0022] Example 1: Reinforced concrete pipe socket interface sediment leakage prevention structure, see Figures 1 to 3 , including a first reinforced concrete pipe 1 and a second reinforced concrete pipe 101, and also including: an annular sealing shell 2, which is sleeved between the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101; a sediment anti-leakage mechanism, which is installed at the upper and lower ends inside the annular sealing shell 2, and the sediment anti-leakage mechanism includes an arc-shaped mesh shell 209, and the arc-shaped mesh shell 209 is filled with a mineral filler 210; an arc-shaped support plate 207 is fixed at one end of the arc-shaped mesh shell 209, and a water-swellable waterproofing cotton 208 is fixed at the end of the arc-shaped support plate 207 away from the arc-shaped mesh shell 209. First, the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101 are respectively inserted from both sides of the annular sealing shell 2, and the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101 are docked. After the docking is completed, the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101 are connected to the annular sealing shell 2 by using a fixing strip and a fixing bolt 202. The elastic force of the spring 204 in the second fixed tube drives the arc-shaped support plate 207 to clamp and seal the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101. Since water-swellable waterproofing cotton 208 is arranged on the surface of the arc-shaped support plate 207, when mud and sand leaks at the interface of the reinforced concrete pipe, water in the mud and sand will contact the water-swellable waterproofing cotton 208, and the water-swellable waterproofing cotton 208 will expand rapidly, thereby actively squeezing and covering the interface position, thereby improving the anti-leakage effect. Moreover, mineral filler 210 is arranged inside the arc-shaped mesh shell 209. The arc-shaped mesh shell 209 and the mineral filler 210 can block the mud and sand to prevent it from leaking out, thereby solving the problem of traditional reinforced concrete pipes, which use seals and plug-ins to connect and seal the socket interface of the reinforced concrete pipe. This sealing method, due to the use of plug-in, will still cause mud and sand leakage as the socket interface position loosens.

[0023] For details, see Figure 2 A first connecting tube 206 is fixed to one end of the arc-shaped lattice shell 209 away from the arc-shaped supporting plate 207 , and the other end of the first connecting tube 206 extends into the second connecting tube 203 .

[0024] For further information, see Figure 2 A connecting plate 205 is fixed to one end of the first connecting tube 206 located in the second fixed tube, and a spring 204 is fixed to one end of the connecting plate 205 away from the first fixed tube.

[0025] It is worth noting that see Figure 3An inner tube body 3 is fixed on one side of the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101, and the two inner tube bodies 3 fit together. Since the inner tube body 3 is arranged inside the reinforced concrete pipe, the reinforced concrete pipes can be butt-jointed through the inner tube body 3 during the butt-jointing installation.

[0026] It is worth noting that see Figure 3 A plurality of circular holes 301 are provided on one side of the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101, and a support rod body 302 is fixed inside the plurality of circular holes 301. The support rod body 302 is used to pass through the two reinforced concrete pipes at the same time, so that the connection position of the two reinforced concrete pipes can be limited and fixed, and cooperated with the external limit connection strip 201 to realize the double limit fixation inside and outside, thereby avoiding the loosening of the connection position of the two reinforced concrete pipes and causing leakage of mud and sand.

[0027] It is worth mentioning that see Figure 1 Connecting strips 201 are fixed to the upper and lower ends of both sides of the annular sealing shell 2. A plurality of fixing bolts 202 penetrate the interior of the connecting strips 201, and the plurality of fixing bolts 202 are threadedly connected to the thread grooves on the surfaces of the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101.

[0028] When using the reinforced concrete pipe socket interface sediment leakage prevention structure, first insert the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101 from both sides of the annular sealing shell 2 respectively, and dock the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101. After docking, use the fixing strips and fixing bolts 202 to connect the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101 and the annular sealing shell 2. Through the elastic force of the spring 204 in the second fixing cylinder, the arc support plate 207 is driven to clamp and seal the first reinforced concrete pipe 1 and the second reinforced concrete pipe 101. Since water-expanding waterproofing cotton 208 is provided on the surface of the arc support plate 207, when sediment leakage occurs at the reinforced concrete pipe interface, the water in the sediment will contact The water-stopping cotton 208 swells when exposed to water. The water-stopping cotton 208 swells rapidly when exposed to water, thereby actively squeezing and covering the position of the interface, thereby improving the anti-leakage effect. Moreover, a mineral filler 210 is arranged inside the arc-shaped mesh shell 209. The arc-shaped mesh shell 209 and the mineral filler 210 can block mud and sand, thereby preventing mud and sand from leaking out. Since an inner tube body 3 is arranged inside the reinforced concrete pipe, during the process of butt-jointing and installation of the reinforced concrete pipes, the inner tube body 3 can be used for butt-jointing. Moreover, the support rod body 302 is used to pass through the two reinforced concrete pipes at the same time, so that the connection position of the two reinforced concrete pipes can be limited and fixed, and cooperated with the external limiting connecting strip 201 to realize internal and external double limiting and fixing, thereby preventing the butt joint position of the two reinforced concrete pipes from loosening and causing leakage of mud and sand.
