Description

Technical Field

[0001] The invention relates to the technical field of pipe network laying, and in particular to a municipal engineering pipe network construction method. Background Art

[0002] Municipal infrastructure projects refer to the civil engineering, pipeline and equipment installation projects of urban roads, public transportation, etc. In the process of modern urban construction, rainwater pipes and sewage pipes are important components and are important indicators of the level of modern cities. Among them, rainwater pipes are pipes that collect natural rainwater on the ground and transport it to natural water bodies, and sewage pipes are pipes that collect sewage generated after people use it. Usually, the sewage needs to be transported to a sewage treatment plant for treatment to meet the discharge standards before being discharged into the water body or recycled.

[0003] At present, the laying method of sewage pipe construction is usually to first use excavators and other equipment to dig linear trenches on the ground, and then cooperate with manual labor to trim the bottom of the trench, place the cement sewage pipe to be buried next to the ditch, and then lift it by a crane, and then control the position of the sewage pipe by manual support, and then dock the pipes. When connecting the pipes, you can use a municipal pipe network road laying pipe connection device with a publication number of CN218408775U. The pipe network road laying pipe connection device can facilitate the connection and fixation of two pipes, and the corresponding bolt method is more convenient and quick, which is conducive to the later maintenance of the pipe. When laying, you can use a pipe network laying device with a publication number of CN212107166U that is easy to prevent friction. The pipe network laying device can carry multiple pipe bodies at the same time for transportation, thereby replacing the form of manual transportation, which is conducive to liberating labor and improving work efficiency. At the same time, the pipe body can be raised and lowered by a scissor lift to adjust the height, which is conducive to transporting the pipe body to a specified height, thereby facilitating workers to install.

[0004] A search revealed that manpower is mostly used in the process of laying pipelines. Due to the weight of the pipelines, position deviations often occur and readjustment is required, which is time-consuming and laborious. At the same time, after the pipelines are moved to the docking position, it is necessary to clean the dirt, dust and other impurities on the plug end wall of the pipeline and apply lubricant, which consumes a lot of manpower and time, thus affecting the construction efficiency of the pipeline network. The noise and air pollution generated during the construction process have caused long-term troubles and impacts on the daily lives of residents near the construction site. Summary of the invention

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0021] For example, see Figure 1-8 The present invention provides a municipal engineering pipe network construction method as follows: First, the pipe body 4 placed beside the ditch is hoisted and placed on the upper surface of the clamping base 504, then the pipe body 4 is moved so that its butt end is inserted into the butt hole 3 and supported by three support rollers 511, then the hoisting rope is retracted, and the clamping ring 505 is fixed to the clamping base 504 by the fixing bolt 506 to clamp the pipe body 4; Then, the driving motor 501 is started to drive the screw rod 502 to rotate, so that the connecting rod 503 drives the pipe body 4 clamped by the clamping base 504 to move into the docking box 2, and the connecting frame plate 507 drives the connecting ring 508 to squeeze the first spring 516, so that the first spring 516 can use the elastic force to make the support plate 509 move with the pipe body 4. Under the guidance of the spiral groove 7, the support plate 509 can drive the multiple cleaning brushes 513 to move around the pipe body 4, so as to realize the synchronous cleaning of the docking end wall of the pipe body 4 during the docking process; Then, during the movement of the support plate 509, the resistance of the third spring 12 is utilized to gradually increase the resistance of the support plate 509 driven by the first spring 516, that is, the pipeline body 4 will move an additional distance while moving synchronously in the same direction as the cleaning brush 513. When the blocking block 13 is completely retracted into the groove 11, the resistance of the support plate 509 driven by the first spring 516 will suddenly decrease, causing the first spring 516 to rebound, that is, the pipeline body 4 will move in the opposite direction to the moving direction of the cleaning brush 513, so that the cleaning brush 513 can move forward and backward to clean the butt end wall of the pipeline body 4 while surrounding it; Then, after the docking moves a certain distance, the side wall of the support plate 509 will contact the stop rod 801 and drive it to move, so that the piston 804 pushes the lubricant in the lubricating cylinder 803, and the lubricant is sprayed on the docking end wall of the cleaned pipeline body 4 through the delivery pipe 805 and the nozzle 806, and the lubricant on the surface of the docking end wall is automatically evenly applied by the three support rollers 511; When the coating is completed, the butt joint ends of the pipe bodies 4 are fitted together, and the support plate 509 cannot move due to the restriction of the stop rod 801. At this time, the drive motor 501 continues to operate. When the support plate 509 cannot move, the clamping base 504 drives the butt joint end wall of the pipe body 4 to insert into the butt joint end wall of the other pipe body 4, thus completing the butt joint. When the docking is completed, first release the two clamping blocks 15 and the clamping ring 505, then control the driving motor 501 to reverse, so that the support plate 509 returns to the initial position, and use the second spring 810 to drive the piston 804 and the push rod 801 back to the initial position. During the return process of the piston 804, the one-way valve 809 is used to draw the lubricant in the storage barrel 808 into the lubrication cylinder 803 through the suction tube 807 for automatic filling. At the same time, during the reversal process of the driving motor 501, the frame 1 is moved at this time, so that the front end wall of the pipe body 4 that has been docked is re-located in the docking hole 3 opened on the side of the docking box 2 away from the clamping base 504, and is clamped again by the two clamping blocks 15. At this time, the next docking operation can be performed.

The cleaning brush 513 will move an additional distance while moving in the same direction. When the blocking block 13 is completely retracted into the groove 11, the resistance of the first spring 516 to drive the support plate 509 to move will suddenly decrease, causing the first spring 516 to rebound, that is, the pipeline body 4 will move in the opposite direction to the moving direction of the cleaning brush 513, so that the cleaning brush 513 can move forward and backward while cleaning the butt end wall of the pipeline body 4, thereby improving the cleaning effect and further ensuring that the contact surface of the butt end wall is good. Furthermore, before docking, the front end walls of the multiple docked pipe bodies 4 will be located in the docking hole 3 opened on the side of the docking box 2 away from the clamping base 504, and the two electric push rods 14 will drive the clamping block 15 to fix it, so that the pipe bodies 4 can be automatically docked without manual control of the docking position; Through the above, when the pipeline network is constructed and laid, the pipeline body 4 can be supported and clamped through the cooperation of the clamping base 504 and the support plate 509, and the pipeline bodies 4 can be automatically docked by the driving motor 501, without the need for manual control of the docking position, thereby ensuring the docking accuracy.
