[0002] Sewage drainage pipes refer to pipe systems that transport sewage generated in buildings and production facilities to sewage treatment facilities for treatment. Corrugated pipes are widely used in sewage drainage pipes due to their good corrosion resistance, flexibility and scalability, as well as easy installation and low cost. The main installation and construction methods of sewage drainage pipes are: pipeline design - trench excavation - pipeline placement - pipeline connection - pipeline testing - backfilling - completion acceptance.

[0003] Since the sewage discharge pipe is long, multiple corrugated pipes need to be arranged in combination.

[0038] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0039] like Figure 1 、 Figure 2 and Figure 3 As shown, a sewage drainage pipe installation and construction method includes the following steps:

[0040] S1. Pipeline design: Design a suitable pipeline system based on factors such as the structure of the building and sewage discharge volume.

[0041] S2. Digging trenches: Digging trenches for pipeline paths on the ground by manual labor and excavators.

[0042] S3. Place pipes: Use a crane to place the prepared pipes into the trench one by one and extend them one by one until the entire layout is completed.

[0043] S4. Connecting pipes: Lift the connecting ends of the two corrugated pipes away from the ground through the lifting mechanism 5 of the docking device to prevent the connecting ends from sticking to the soil and affecting the sealing of the connection during the subsequent movement; then use the push-pull mechanism 4 to drive one of the corrugated pipes to move toward the other corrugated pipe, connect the ends together, and dock them in the form of a large diameter inside a small diameter, so that the connection is a whole.

[0044] S5. Test pipelines: Perform pressure tests and water tightness checks on connected pipelines to ensure there are no leaks in the pipelines to ensure their service life in the future.

[0045] S6. Backfill: Fill the previously excavated soil back into the trench and tamp it to secure the pipe in the trench.

[0046] S7. Completion acceptance: Conduct comprehensive acceptance of the entire piping system to ensure compliance with relevant standards and specifications.

[0047] Among them, the docking device involved in the above-mentioned S4 step includes a base 1, the number of the bases 1 is four, and each two bases 1 form a group. The two groups of bases 1 are symmetrical left and right, and the two bases 1 in each group are symmetrical front and back. A roller 2 is installed on the upper end surface of the base 1, and a resistance block 3 is slidably installed on the lower end of the base 1. The resistance block 3 is a right-angled trapezoidal structure. A push-pull mechanism 4 for pulling the sewage pipe to dock is commonly provided between the bases 1, and a lifting mechanism 5 for driving the resistance block 3 is provided between the two bases 1 on the left.

[0048] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 As shown, the lifting mechanism 5 includes a fixed block 50, and the two symmetrical bases 1 are provided with fixed blocks 50 on the opposite sides. A shaft 51 is slidably installed between the two symmetrical fixed blocks 50. The upper end surface of the fixed block 50 on the left is installed with a stepper motor 52 through a motor seat. The stepper motor 52 is connected to the shaft 51 through a pulley mechanism. A spur gear 53 is rotatably installed on the right end surface of the fixed block 50, and the spur gear 53 and the shaft 51 are matched through a spline. The upper end surface of the interference block 3 is evenly provided with teeth 54 that mesh with the spur gear 53.

[0049] During specific operation, the stepper motor 52 drives the shaft 51 to rotate through the pulley mechanism. Since the shaft 51 and the spur gear 53 are matched through the spline, the shaft 51 will drive the spur gear 53 to rotate during the rotation of the shaft 51. The rotation of the spur gear 53 pushes the resistance block 3 to move toward the direction of the bellows. The inclined surface of the resistance block 3 conflicts with the bellows, and as the resistance block 3 moves, the connecting end of the bellows is lifted away from the ground, thereby avoiding contamination of the connecting end of the bellows during the docking process, affecting the sealing of the bellows after docking.

[0050] like Figure 3 、 Figure 4 and Figure 5 As shown, the push-pull mechanism 4 includes a telescopic cylinder 40, and the left side of the base 1 is hinged with a telescopic cylinder 40. The telescopic ends of the two telescopic cylinders 40 symmetrical on the left and right are slidably installed with a support rod 41. The right ends of the two support rods 41 are jointly installed with a No. 1 fixed plate 42, and the left ends of the two support rods 41 are jointly slid with a No. 2 fixed plate 43, and the No. 1 fixed plate 42 and the No. 2 fixed plate 43 have the same structure and are both arc-shaped structures. A pipe column 44 is slidably installed on the left side of the two support rods 41, and a compression spring 45 is arranged between the left side of the pipe column 44 and the No. 2 fixed plate 43. The pipe column 44 is provided with a clamping moving unit 6 for driving the support rod 41 to move.

[0051] like Figure 3 、 Figure 4 、 Figure 5 and Figure 6As shown, the clamping and moving unit 6 includes a pressing plate 60. The upper part of the upper end of the second fixing plate 43 is rotatably installed with a pressing plate 60 through a shaft plate. A connecting plate 61 is hinged to the lower end surface of the pressing plate 60. The lower end of the connecting plate 61 is hinged to the pipe column 44. Grooves are evenly opened in the pipe column 44 along its circumferential direction. Clamping blocks 62 are rotatably installed in the grooves through torsion springs, and the clamping blocks 62 deflect towards the second fixing plate 43. On the upper end surfaces of the two bases 1 on the left side, a support plate 63 is jointly installed, and the support plate 63 has an inverted U-shaped structure. A connecting member 64 connecting the two pressing plates 60 is provided on the horizontal section of the support plate 63. A driving member 65 for driving the connecting member 64 to move up and down reciprocally is provided on the support plate 63.

[0052] During specific operation, the driving member 65 drives the connecting member 64 to move up and down reciprocally. When the connecting member 64 moves up and down reciprocally, it will push the pressing plate 60 to rotate up and down reciprocally. During the process of the pressing plate 60 being pushed to rotate downward, the pressing plate 60 approaches the support rod 41, and the connecting plate 61 is pushed to the left side. The connecting plate 61 will push the pipe column 44 to move towards the second fixing plate 43 and compress the compression spring 45 at the same time. During the process of the pipe column 44 moving towards the second fixing plate 43, the clamping block 62 will contact the support rod 41, thereby clamping the support rod 41. The support rod 41 moves to the left side synchronously with the pipe column 44, and the first fixing plate 42 pulls the corrugated pipe to be docked with the corrugated pipe under the second fixing plate 43. During the process of the first fixing plate 42 moving to the left side, the telescopic oil cylinder 40 is used to drive the base 1, the fixing block 50, the spur gear 53 and the abutting block 3 on the right side to move to the left side synchronously, so as to ensure that the connecting part of the corrugated pipe always remains away from the ground during the docking process and keep the connection part clean. After the docking is completed, move this docking device to the next position that needs to be docked for the next docking processing work.

[0053] As Figure 6 shown, the end face of the clamping block 62 close to the support rod 41 has an isosceles triangle structure; during specific operation, the isosceles triangle structure of the clamping block 62 ensures the smooth sliding of the clamping block 62 during the rightward movement of the pipe column 44 on the one hand, and increases the extrusion force of the clamping block 62 on the support during the leftward movement of the pipe column 44 on the other hand, ensuring that the support rod 41 moves synchronously along with the clamping block 62.

[0054] As Figure 2 and Figure 5 shown, the widths of the first fixing plate 42 and the second fixing plate 43 are both smaller than the grooves on the corrugated pipe; during specific operation, the widths of the first fixing plate 42 and the second fixing plate 43 are both smaller than the grooves on the corrugated pipe, so as to facilitate the first fixing plate 42 and the second fixing plate 43 to be clamped into the grooves of the corrugated pipe, thereby improving the efficiency of fixing the corrugated pipe.

[0055] As Figure 5 and Figure 7As shown, the connecting member 64 includes a slide rod 640, and two slide rods 640 are provided on the upper end surface of the support plate 63 corresponding to the pressure plate 60, and the slide rod 640 slides with the support plate 63, and the upper and lower ends of the slide rod 640 extend to the upper and lower end surfaces of the horizontal section of the support plate 63 respectively, and the lower end of the slide rod 640 is installed with a support block 641, and a waist-shaped groove 642 is provided on the support block 641. The right side of the two pressure plates 60 is provided with a No. 1 shaft column that slides with the waist-shaped groove 642. The upper end surfaces of the two slide rods 640 are jointly provided with a connecting plate 643, and the upper end surface of the support plate 63 is provided with a driving member 65 for driving the slide rod 640 to move back and forth up and down.

[0056] like Figure 5 and Figure 8 As shown, the driving member 65 includes a long plate 650, and the lower end surface of the connecting plate 643 is rotatably and slidingly installed with the long plate 650 through the shaft seat, and the side of the long plate 650 close to the left end is rotatably installed with the support plate 63 through the shaft plate, and the upper end surface of the support plate 63 is rotatably installed with the No. 2 shaft column through the fixed seat 651, and a turntable 652 is installed on the No. 2 shaft column, and a column 653 is eccentrically installed on the front end surface of the turntable 652, and the column 653 is rotatably matched with the left side of the long plate 650, and the long plate 650 and the column 653 are slidably matched.

[0057] During specific operation, the external motor is installed on the support plate 63 through the motor seat, and the output shaft of the external motor is connected to the No. 2 shaft column. The operation of the external motor drives the No. 2 shaft column to rotate, and the No. 2 shaft column drives the turntable 652 to rotate. During the process of the turntable 652 rotating from low to high through the column 653, it will drive the left end of the long plate 650 to rotate upward, and the right end of the long plate 650 will rotate downward to push the connecting plate 643 to move downward. The connecting plate 643 pushes the support block 641 downward through the two sliding rods 640, and the support block 641 drives the pressure plate 6 0 rotates downward, thereby clamping the support rod 41 to move to the left through the clamping block 62, and the support rod 41 drives the right side of the corrugated pipe to move to the left through the first fixing plate 42 to dock with the left side of the corrugated pipe. When the column 653 rotates from a high position to a low position, it drives the right end of the long plate 650 to rotate upward, so that the sliding rod 640 moves up, and the clamping block 62 slides to the right along the support rod 41 with the pipe column 44 to realize the reset of the pipe column 44, thereby realizing the reciprocating movement of the pipe column 44 and slowly driving the corrugated pipe to the left through the first fixing plate 42 for docking.
