Description

Technical Field

[0001] This application relates to the technical field of drainage pipes, and in particular to an energy-saving and environmentally friendly drainage pipe structure for buildings. Background Technology

[0002] Drainage pipes are important facilities in buildings, urban infrastructure, and industrial systems used to collect, transport, and discharge liquids such as rainwater, sewage, and industrial wastewater. They play a key role in ensuring urban operation, environmental protection, flood control, and drainage.

[0003] The existing announcement number CN215806975U, entitled "A Drainage Pipe," relates to the technical field of pipe connection. It addresses the problem of water leakage at pipe connections after long-term use. The pipe includes a first pipe with a second pipe inserted at one end. A waterproof connection mechanism is movably connected to the outer wall of the first pipe. A first flange is welded to the outer wall of the second pipe. One side of the first flange is connected to the waterproof connection mechanism via a connecting bolt. A second sealing ring is provided between the first and second pipe contact surfaces to enhance the sealing effect at the connection. The connecting annular plate of the waterproof connection mechanism is located inside an annular connecting groove. The waterproof connection mechanism is connected to the first flange via a connecting bolt, allowing for a tighter connection between the first and second pipes, thereby enhancing the leak-proof effect at the pipe connection and preventing water leakage from the pipe connection from polluting the land.

[0004] Regarding the aforementioned technologies, the inventors discovered that the drainage pipes are made of cast iron, which consumes a lot of energy, has high transportation and installation costs, and will corrode during use, resulting in a reduced service life, inconvenient replacement, and increased replacement costs. Utility Model Content

[0005] To overcome the problems of existing drainage pipes being made of cast iron, which have high energy consumption, high transportation and installation costs, and are prone to corrosion during use, resulting in reduced service life, inconvenient replacement, and increased replacement costs, this application provides an energy-saving and environmentally friendly drainage pipe structure for buildings.

[0006] The technical solution for an energy-saving and environmentally friendly drainage pipe structure for buildings provided in this application is as follows: An energy-saving and environmentally friendly drainage pipe structure for buildings includes drainage pipes and connecting fittings. The drainage pipe includes a cast iron water cylinder, concrete filler, an asphalt sleeve, and PVC filler. The outer wall of the cast iron water cylinder is filled with concrete filler, and the cast iron water cylinder and concrete filler are integrally cast. An asphalt sleeve is fitted on the outer wall of the concrete filler of the cast iron water cylinder, and PVC filler is provided on the inner circumference of the cast iron water cylinder. The cast iron water cylinder and PVC filler are integrally formed. Both ends of the cast iron water cylinder are vertically connected and fixed with connecting ring plates, and the center of the connecting ring plates at both ends of the cast iron water cylinder is horizontally connected and fixed with connecting inserts and connecting tubes, respectively. Multiple adjacent connecting inserts and connecting tubes of the drainage pipes are inserted and connected. Connecting fittings are provided at the connecting ends of the drainage pipes and are used to seal the adjacent ends of the drainage pipes.

[0007] By adopting the above technical solution, in order to improve the service life of the drainage pipe, a cast iron water cylinder is installed in the drainage pipe. The high strength of the cast iron water cylinder improves the overall strength of the drainage pipe. Then, concrete filler is installed on the outer wall of the cast iron water cylinder. The concrete filler covers the cast iron water cylinder, improving the service life of the drainage pipe. At the same time, an asphalt sleeve is installed on the outside of the concrete filler. The asphalt sleeve prevents water from seeping into the cast iron water cylinder from the soil layer, reducing the corrosion of the cast iron water cylinder and ensuring the service life of the drainage pipe. Similarly, PVC filler is installed inside the cast iron water cylinder. The corrosion resistance of PVC filler improves the service life of the drainage pipe. The docking plugs and connecting sleeves at both ends of the drainage pipe are used to complete the docking assembly of adjacent ends of the drainage pipe. Thus, the internal and external measures of the drainage pipe improve corrosion resistance, improve the service life of the drainage pipe, reduce the number of replacements, and reduce the cost of replacing drainage pipes.

[0008] Optionally, multiple support plates are evenly and vertically fixed on the outer wall of the cast iron water cylinder, and multiple pillars are horizontally fixed on the outer wall of the multiple support plates.

[0009] By adopting the above technical solution, multiple support plates and pillars are installed on the outer wall of the cast iron water cylinder to support the concrete filler, effectively ensuring the adhesion stability of the concrete filler covering the cast iron water cylinder.

[0010] Optionally, the mating ring plate on one end face of the cast iron water cylinder is horizontally provided with inserts, and there are multiple inserts, and the multiple inserts are fixed on the mating ring plate.

[0011] By adopting the above technical solution, multiple inserts are set on the connecting ring plate at one end of the cast iron water cylinder to ensure the effective connection of the connecting ring plate assembly at the end of the cast iron water cylinder.

[0012] Optionally, the other end face of the cast iron water cylinder has a horizontally opened ring plate with multiple slots, and the multiple slots are inserted into multiple plug blocks for limiting.

[0013] By adopting the above technical solution, when adjacent ends of the drainage pipe are inserted and connected, multiple inserts at one end of the cast iron water cylinder inside the drainage pipe are inserted and connected to multiple slots at the adjacent ends to ensure the stability of the insertion and connection of adjacent ends of the drainage pipe.

[0014] Optionally, multiple rubber rings are arranged horizontally and vertically inside the connecting cylinder, and these rubber rings are fixed to the inner wall of the connecting cylinder.

[0015] By adopting the above technical solution, multiple rubber rings fixed inside the connecting sleeve are used to fill the gap between the connecting sleeve and the connecting sleeve when adjacent ends of the drainage pipe are inserted and connected, thus ensuring the sealing of the connecting sleeve and the connecting sleeve at the end of the drainage pipe.

[0016] Optionally, multiple inner columns are uniformly fixed on the inner circumference of the cast iron water cylinder, and the multiple inner columns are inserted into PVC filler, the inner circumference of which is coated with a paint layer.

[0017] By adopting the above technical solution, multiple inner columns fixed on the inner circumference of the cast iron water cylinder are used to support the stability of the coated PVC filler. The inner wall of the PVC filler is coated with a coating layer, which is made of epoxy resin. The coating layer has the advantages of high adhesion, chemical corrosion resistance and good water resistance, thus ensuring the service life of the drainage pipe.

[0018] Optionally, the connecting parts include connecting rings, with two connecting rings symmetrically arranged and the two connecting rings symmetrically snapped into the connecting ends of the drainage pipe.

[0019] By adopting the above technical solution, when connecting drainage pipes, a connecting piece is set at the adjacent ends of the two drainage pipes. The two connecting rings in the connecting piece are symmetrically snapped into the connecting ends of the drainage pipes to lock and seal the connected drainage pipes.

[0020] Optionally, both ends of the mating rings are vertically fixed with screw holes, and the screw holes at adjacent ends of the two mating rings are assembled by locking bolt threads.

[0021] By adopting the above technical solution, the locking bolt at the end of the rotating docking ring is threaded through the screw hole seat at the end of the docking ring to lock the two docking rings in a sealed and clamped connection for the drainage pipe.

[0022] In summary, this application includes at least one of the following beneficial technical effects: To extend the service life of the drainage pipe, a cast iron water cylinder is installed. The high strength of the cast iron water cylinder enhances the overall strength of the drainage pipe. Concrete filler is then installed on the outer wall of the cast iron water cylinder, covering it and extending its service life. Simultaneously, an asphalt sleeve is fitted over the concrete filler, preventing water from seeping into the cast iron water cylinder and reducing corrosion, thus ensuring the drainage pipe's service life. Similarly, PVC filler is installed inside the cast iron water cylinder, utilizing its corrosion resistance to further extend the drainage pipe's service life. The connecting sleeves and connecting plugs at both ends of the drainage pipe complete the connection and assembly of adjacent ends. Therefore, the internal and external components of the drainage pipe further reduce corrosion, extend its service life, reduce replacement frequency, and lower the cost of replacing the drainage pipe.
