Description
Technical Field
[0001] The utility model belongs to the field of pipeline anti-leakage structures, in particular to a concrete sewage pipeline anti-leakage structure. Background Art
[0002] Sewage treatment plants are facilities used to treat urban domestic sewage or industrial wastewater. They receive sewage from urban drainage systems and purify it through a series of physical, chemical and biological treatment processes before discharging it into natural water bodies. The most widely used pipes in sewage treatment plants are concrete sewage pipes. Concrete sewage pipes are made of concrete materials and are underground pipe systems used to transport urban or industrial sewage. They are usually composed of prefabricated concrete pipe sections, which are connected together through various interfaces (such as socket, tongue and groove or flange interfaces) to form a continuous underground passage.
[0003] In the existing concrete sewage pipes, when the pipe sections are installed, the pipe seams at the interfaces of the two concrete sewage pipes need to be sealed with cement to prevent leakage. The existing sealing method is to manually apply cement to the pipe seams. However, the manual application of cement may result in uneven cement application, resulting in weak leakage prevention of the pipe seams in some areas, and sewage leakage after a period of use. Utility Model Content
[0004] The utility model aims to provide a concrete sewage pipe anti-leakage structure, which can evenly cover cement on the pipe seam between two concrete sewage pipes to prevent sewage from leaking from the pipe seam.
[0005] The concrete sewage pipe anti-leakage structure comprises two arc-shaped plates, one ends of the two arc-shaped plates are hinged to each other, and storage grooves aligned with the pipe seams and used to store cement are provided on the inner circular surfaces of the arc-shaped plates along their circumferential directions; the two arc-shaped plates are ring-shaped after being swung closed, and the two storage grooves are connected and combined to form an annular channel; the other ends of the two arc-shaped plates are detachably connected, a filling pipe connected to the storage groove is fixed on one of the arc-shaped plates, and side plates with an arc-shaped structure and used to clamp the concrete sewage pipe are fixed on the two side walls of each arc-shaped plate.
[0006] Furthermore, mounting grooves are provided on the inner circular surfaces of all the side plates along the circumferential direction thereof, and a sealing strip is engaged in each mounting groove for preventing cement and sewage from flowing out of the gap between the side plate and the concrete sewage pipe.
[0007] Furthermore, a plurality of evenly distributed protrusions are fixed on the inner circumferential surfaces of all the side panels.
[0008] Furthermore, all the bumps are in a conical structure.
[0009] Furthermore, fixed plates are fixed on the swinging ends of the two arc-shaped plates. After the two arc-shaped plates are swung closed, the two fixed plates fit each other, and the two fixed plates are connected by bolts.
[0010] Furthermore, alignment lines for aligning the pipe seams between two concrete sewage pipes are provided on all the fixing plates and the filling pipes.
[0011] Furthermore, all curved plates and all side plates are coated with an anti-rust coating on their surfaces.
[0012] Compared with the prior art, the utility model has the following beneficial effects:
[0013] After the two arc plates are swung and closed, they are combined into an annular structure, which surrounds the butt joint between the two concrete sewage pipes. The annular channel formed by the storage tank is aligned with the pipe seam between the two concrete sewage pipes. The swing ends of the two arc plates are locked by bolts, and finally cement is filled into the annular channel from the filling pipe. Under the action of gravity, the cement will gradually submerge the pipe seam between the two concrete sewage pipes from bottom to top, so that the cement can evenly cover the pipe seam between the two concrete sewage pipes, ensuring that the cement thickness and coverage area in each area are roughly the same, thereby avoiding the occurrence of weak anti-leakage points on the pipe seam, improving the anti-leakage effect of the pipe seam, and avoiding sewage leakage; the side plates on the front and rear side walls of the two arc plates respectively clamp and fix the butt joint ends of the two concrete sewage pipes to prevent the two concrete sewage pipes from moving and loosening, and the sealing strip on each side plate can seal the gap between the side plate and the concrete sewage pipe to prevent a large amount of cement or sewage from leaking from the gap.

[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
[0021] Example 1
[0022] The concrete sewage pipe anti-leakage structure described in this embodiment is as follows: Figure 1 , Figure 2 and Figure 5 As shown, it includes two arc-shaped plates 1, one end of the two arc-shaped plates 1 is hinged to each other, and the two arc-shaped plates 1 are hinged by hinges, and of course, they can also be hinged by bearings, so that the two arc-shaped plates 1 can swing against each other, and the two arc-shaped plates 1 are semicircular in structure. When the ends of the swinging ends of the two arc-shaped plates 1 are attached, the combination is a circular ring; the arc-shaped plates 1 are made of iron, steel or other metal materials;
[0023] The inner circular surface of the arc plate 1 is provided with storage grooves 5 along its circumferential direction, which are aligned with the pipe seams and used to store cement. The storage grooves 5 are arc-shaped grooves located at the center of the inner circular surface of the arc plate 1. In use, the storage grooves 5 are aligned with the pipe seams between two concrete sewage pipes, and cement is added to the storage grooves 5 to seal the pipe seams. Of course, the storage grooves 5 can also be rectangular grooves or grooves of other shapes.
[0024] The two arc-shaped plates 1 are swung and closed to form a circular ring, and the two storage grooves 5 are connected and combined to form a circular channel. Figure 3 As shown, when the ends of the swing ends of the two arc-shaped plates 1 are fitted together, the two ends of the storage grooves 5 on the two arc-shaped plates 1 are connected to each other, so that the storage grooves 5 on the two arc-shaped plates 1 are combined into an annular channel; in use, when cement is added to the annular channel, the cement will gradually flood the pipe seam between the two concrete sewage pipes from bottom to top under the action of gravity, so that the cement can evenly cover the pipe seam between the two concrete sewage pipes, ensuring that the cement thickness and coverage area in each area are roughly the same, thereby avoiding the occurrence of anti-leakage weak points on the pipe seam and improving the anti-leakage effect of the pipe seam;
[0025] The other ends of the two arc-shaped plates 1 are detachably connected, and a fixing plate 4 is fixed on the swinging ends of the two arc-shaped plates 1. After the two arc-shaped plates 1 are swung closed, the two fixing plates 4 fit each other, and the two fixing plates 4 are connected by bolts; the two fixing plates 4 are respectively fixed at the edges of the swinging ends of the two fixing plates 4, and the side walls of the fixing plates 4 are flush with the end faces of the swinging ends of the corresponding fixing plates 4. Through holes for bolts to pass through are opened on the two fixing plates 4. When the two fixing plates 4 fit together, the bolts are screwed in. The threaded end of the bolt passes through the through holes on the two fixing plates 4, and the nut is mounted on the bolt to lock the two fitting fixing plates 4, thereby locking the two arc-shaped plates 1 after swinging and closing; of course, the swinging ends of the two arc-shaped plates 1 can also be bolts, a clamping block is fixed on the swinging end of one arc-shaped plate 1, and a clamping groove for clamping the clamping block is provided on the swinging end of the other arc-shaped plate 1, and a through hole for inserting the bolt is provided in the clamping block and the clamping groove, and the bolt and the through hole are in interference fit;
[0026] A filling pipe 3 communicating with the storage tank 5 is fixed on one of the arc-shaped plates 1. Figure 3 As shown, the filling pipe 3 is a round pipe, which is fixed on the swing end of one of the arc-shaped plates 1 and communicates with the storage tank 5. In use, when the swing ends of the two arc-shaped plates 1 are closed, the swing ends of the two arc-shaped plates 1 face upward, and the filling pipe 3 faces upward, thereby preventing cement from flowing out of the filling pipe 3;
[0027] An alignment line 8 for aligning the pipe seam between two concrete sewage pipes is provided on all the fixing plates 4 and the filling pipe 3; the alignment line 8 is provided on the end surface of the fixing plate 4 and the filling pipe 3 at the unfixed end, and the alignment line 8 is aligned with the center of the storage tank 5. When the positions of the two arc-shaped plates 1 are adjusted before closing, the alignment line 8 is aligned with the pipe seam between the two concrete sewage pipes, so that the pipe seam is aligned with the center of the storage tank 5, thereby ensuring that cement can be evenly covered on the pipe seam;
[0028] Side plates 2 with an arc-shaped structure and used for clamping concrete sewage pipes are fixed on both side walls of each arc plate 1. The side plates 2 are semicircular in structure and have the same diameter as the arc plate 1. When the two arc plates 1 are swung closed, the side plates 2 on the front side walls of the two arc plates 1 can clamp and fix the concrete sewage pipe in front, and the side plates 2 on the rear side walls of the two arc plates 1 can clamp and fix the concrete sewage pipe in the rear, so as to prevent the two combined butt-jointed concrete sewage pipes from loosening and ensure the tightness of the pipe seam between the two concrete sewage pipes.
[0029] The inner circular surface of all the side plates 2 is provided with a mounting groove along the circumferential direction thereof, and a sealing strip 6 for preventing cement and sewage from flowing out of the gap between the side plate 2 and the concrete sewage pipe is engaged in each mounting groove; the mounting groove is provided on one side of the inner circular surface of each side plate 2 close to the arc plate 1, and when the two arc plates 1 are swung closed, the sealing strip 6 will form a ring, and when the side plates 2 on the two arc plates 1 are clamped on the concrete sewage pipe, the sealing strip 6 will be squeezed and tightly attached to the concrete sewage pipe, thereby sealing the gap between the side plate 2 and the concrete sewage pipe to prevent cement from flowing out, and when the cement is broken, the leaked sewage can be secondary sealed to prevent the leaked sewage from seeping out of the arc plate 1 in large quantities;
[0030] A number of evenly distributed protrusions 7 are fixed on the inner circular surfaces of all side panels 2. All protrusions 7 are in a conical structure, and the tips of all protrusions 7 face the concrete sewage pipe. When the side panels 2 are clamped on the concrete sewage pipe, the protrusions 7 can be embedded in the pipe body, thereby avoiding the concrete sewage pipe and the side panels 2 from slipping, preventing the concrete sewage pipe from falling off, and improving the fixing effect of the side panels 2;
[0031] The surfaces of all curved plates 1 and all side plates 2 are coated with an anti-rust coating; the anti-rust coating includes epoxy powder, polyester powder, paint, coating, polyethylene (PE) coating, polypropylene (PP) coating or ceramic coating, etc.; the anti-rust coating can improve the corrosion resistance of all curved plates 1 and all side plates 2, and increase the service life of all curved plates 1 and all side plates 2.
[0032] In actual use, when the two concrete sewage pipes are butt-jointed, one of the arc plates 1 is passed through the bottom of the butt joint of the two concrete sewage pipes, so that the hinge point of the two arc plates 1 is located directly below the butt joint of the two concrete sewage pipes, and the positions of the two arc plates 1 are adjusted to align the pipe seam between the two concrete sewage pipes with the center of the storage tank 5, and then the two arc plates 1 are swung closed, and the swing ends of the two arc plates 1 are locked by bolts, so that the annular structure composed of the two arc plates 1 surrounds the butt joint between the two concrete sewage pipes, and the side plates 2 on the front and rear side walls of the two arc plates 1 respectively connect the two concrete sewage pipes. The butt ends of the pipes are clamped and fixed to prevent the two concrete sewage pipes from moving and loosening. The sealing strip 6 on each side plate 2 seals the gap between the side plate 2 and the concrete sewage pipe to prevent a large amount of cement or sewage from leaking from the gap. Finally, cement is added to the annular channel from the filling pipe 3. Under the action of gravity, the cement will gradually submerge the pipe gap between the two concrete sewage pipes from bottom to top, so that the cement can be evenly covered on the pipe gap between the two concrete sewage pipes, ensuring that the cement thickness and coverage area in each area are roughly the same, thereby avoiding weak anti-leakage points on the pipe gaps, improving the anti-leakage effect of the pipe gaps, and avoiding sewage leakage.
