Description

Technical Field

[0001] This utility model relates to the field of HPVC pipe technology, and in particular to an HPVC pipe with strong pressure resistance. Background Technology

[0002] HPVC pipe, or high-strength polyvinyl chloride pipe, is a high-performance new type of pipe. It has the characteristics of high strength, high toughness, strong corrosion resistance, resistance to termite damage, weather resistance, UV resistance, anti-aging, good weather resistance, good flame retardancy, and hot-melt welding. It is widely used in various construction fields such as outdoor bridge cladding, tunnels, light rail, airports, subways, stadiums, and real estate for the protection of buried communication optical (electrical) cables and power cables. It can also be used for trenchless pipeline construction.

[0003] When in use, HPVC pipes are mainly connected by welding. The welded joints have high strength and good sealing performance, which can effectively prevent water and air leakage. However, they cannot be disassembled during maintenance, making operation inconvenient. Welding also requires specific tools and involves complex procedures. When the surface of the HPVC pipe is subjected to pressure, it is easily damaged by stress, affecting its service life. Therefore, we propose an HPVC pipe with strong pressure resistance. Utility Model Content

The inner surfaces of both the first pipe body and the second pipe body are fitted with reinforcing structures, and there are two sets of reinforcing structures.

[0007] Furthermore, the connection structure includes a first fixing ring, an insert plate, a second fixing ring, an insert groove, a fixing bolt, and a first fixing hole. An insert plate is fixedly installed on one side surface of the first fixing ring. There are four sets of insert plates. The surface of each insert plate is provided with a first fixing hole. An insert groove is provided on one side surface of the second fixing ring. There are four sets of insert grooves. The first fixing ring is located on one side of the second fixing ring. The insert plates are respectively embedded in the insert grooves. There are four sets of fixing bolts.

[0008] Furthermore, the second tube body includes a tube body and a second fixing hole. The second fixing hole is provided on one side of the surface of the tube body, and there are four sets of the second fixing holes.

[0009] Furthermore, the first tube body is located on one side of the tube body, the first fixing ring is sleeved and installed on the surface of the first tube body at one side, the second fixing ring is sleeved and installed on the surface of the tube body at one side, and the fixing bolt is embedded in the inside of the first fixing hole and the second fixing hole.

[0010] Furthermore, the reinforcing structure includes a protective layer, reinforcing ribs, and mounting rings. There are two sets of mounting rings, and the protective layer is fixedly connected between the mounting rings. Reinforcing ribs are fixedly connected between the mounting rings on the surface of the protective layer, and there are multiple sets of reinforcing ribs.

[0011] Furthermore, the mounting rings are respectively embedded in the interior of the first tube body at both sides and the interior of the tube body at both sides.

[0012] In summary, due to the adoption of the above technical solution, the beneficial effects of this application are:

[0013] 1. The connection structure allows for quick and tight connection between the first and second pipe bodies, facilitating disassembly and providing high flexibility.

[0014] 2. The reinforced structure enhances the compressive strength of the first and second pipe bodies, thus improving the service life of the HPVC pipe. Attached Figure Description
