These connection structures have smooth surfaces and lack designs to increase friction. When the pipe is subjected to external soil pressure, vibration, or changes in internal fluid pressure, relative sliding can easily occur between the cap and the pipe body, leading to loosening of the connection, damage to the sealing of the cement pipe, and a series of serious consequences. Therefore, the above problems need to be solved. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Example: See Figure 1-5This utility model discloses a socket-type reinforced concrete cement pipe, comprising a protective pipe 3, with an insulation pipe 2 fixedly connected to the inner wall of the protective pipe 3. The insulation pipe 2 significantly reduces the heat loss of the medium inside the pipe, making it suitable for conveying media with temperature requirements. A placement groove is provided at the connection between the protective pipe 3 and the insulation pipe 2, and a steel bar assembly is placed in the placement groove. A top cover 1 is provided on the top of the protective pipe 3, which effectively seals the top of the pipe and protects the internal structure from external interference. A fastening steel ring 6 abuts against the connection between the top cover 1 and the protective pipe 3, which ensures a firm connection between the top cover 1 and the protective pipe 3 and prevents loosening or falling off during use. A material injection port 8 is provided on the top of the top cover 1, which optimizes the concrete pouring process, makes the material injection smoother, reduces blockage during the pouring process, and improves construction quality and efficiency. The material injection port 8 is T-shaped and located on the top cover 1.

[0021] In this utility model, the reinforcing bar assembly consists of multiple longitudinal reinforcing bars 12 and a reinforcing bar ring 13 sleeved around the outer ring of the longitudinal reinforcing bars 12. The reinforcing bar ring 13 is connected to each longitudinal reinforcing bar 12 by a wire 14 for fixing. The reinforcing bar assembly facilitates the improvement of the comprehensive mechanical properties of the cement pipe, ensuring its stability under various complex working conditions. The fastening steel ring 6 includes a first toothed surface 9 abutting against the outer wall of the protective pipe 3 and a second toothed surface 11 engaging with the first toothed surface 9. Fixing blocks are provided at both ends of the second toothed surface 11, and a bolt 10 for fixing is screwed between the two fixing blocks. The first toothed surface 9 enhances the fastening effect of the fastening steel ring 6, ensuring a tight connection between the top cover 1 and the protective pipe 3, improving the overall sealing and structural stability of the pipeline. The insulation pipe 2 contains... The wall of the insulated pipe 2 is welded with a lifting ring block 7, which is made of cast steel. The lifting ring block 7 provides a reliable lifting connection point, ensuring the safety and stability of the cement pipe during the lifting process and improving construction efficiency. The inner wall of the insulated pipe 2 is fixed with a waterproof layer 4 and an anti-corrosion layer 5. Both the waterproof layer 4 and the anti-corrosion layer 5 have grooves for the lifting ring block 7, and the inner ring of the groove is fitted with a sealing gasket. The anti-corrosion layer 5 helps to reduce the frequency of pipe maintenance and replacement due to corrosion, thereby reducing the cost of use. The insulated pipe 2 uses polyurethane foam insulation board with good thermal insulation performance, and the waterproof layer 4 uses a polymer waterproof membrane layer. The waterproof layer 4 effectively prevents water intrusion, avoids the decline in thermal insulation performance and steel corrosion caused by water, and extends the service life of the cement pipe.

[0022] Working Principle: In the application of this utility model, when manufacturing the socket-type reinforced concrete cement pipe, a steel reinforcement group is first constructed by arranging multiple longitudinal steel bars 12 along the pipe axis. Then, a steel bar ring 13 is fitted around the outer ring of the longitudinal steel bars 12, and the steel bar ring 13 is tied and fixed to the longitudinal steel bars 12 using wire 14 to form a stable steel reinforcement skeleton. The steel reinforcement group is placed in the placement groove at the connection between the protective pipe 3 and the insulation pipe 2. The protective pipe 3 provides external mechanical support, and the insulation pipe 2 uses polyurethane foam insulation board, which has good insulation properties. To improve insulation performance, the waterproof layer 4 and anti-corrosion layer 5 are then installed on the inner wall of the insulation pipe 2. Both layers have pre-drilled slots for lifting ring blocks 7, with sealing gaskets fitted inside the slots. The lifting ring blocks 7 are made of cast steel and welded to the corresponding slot positions on the inner wall of the insulation pipe 2 for subsequent lifting and handling. Next, the top cover 1 is installed. The first tooth surface 9 of the fastening steel ring 6 abuts against the outer wall of the protective pipe 3, and the second tooth surface 11 engages with the first tooth surface 9. The two fixing blocks are connected by screw bolts 10, ensuring a tight fixation between the top cover 1 and the protective pipe 3. At this point, concrete is injected through the T-shaped injection port 8 at the top of the top cover 1, filling the space between the protective pipe 3, the insulation pipe 2, and the reinforcing steel assembly. After the concrete solidifies, a socket-type reinforced concrete cement pipe with high strength, insulation, waterproofing, and corrosion resistance is formed. During the pipe installation process, it is connected to the hoisting equipment through the lifting ring block 7 and the cement pipe is hoisted to the designated location. During use, the protective pipe 3 withstands external pressure, loads, and impact forces during transportation and installation. It works in conjunction with the reinforcing steel assembly to improve the pipe's compressive and flexural strength, ensuring the pipe maintains structural stability under various working conditions. The insulation pipe 2 reduces heat exchange between the medium inside the pipe and the outside environment, making it suitable for conveying media with temperature requirements. The waterproof layer 4 prevents water from penetrating into the pipe, avoiding water erosion of the insulation layer and the reinforcing steel assembly, and ensuring the insulation performance and the stability of the reinforcing steel. The anti-corrosion layer 5 isolates the medium inside the pipe from external corrosive substances and the inner wall of the cement pipe, preventing chemical corrosion and extending the service life of the pipe. This concludes the use of the socket-type reinforced concrete cement pipe.

Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
