Description

Technical Field

[0001] The utility model relates to the technical field of pipelines, in particular to a pipeline protection structure for trench backfilling. Background Art

[0002] Pipelines are mainly used in water supply, drainage, heating, gas supply, long-distance transportation of oil and natural gas, agricultural irrigation, water conservancy projects and various industrial installations. Currently, most pipelines are usually buried underground. The process of burying pipelines underground is also called trench backfilling.

[0003] Currently, in the process of trench backfilling, the pipeline is usually arranged in the trench first, and then filler is used to fill the gaps on both sides of the pipeline and mechanically compacted. However, in order to improve the corrosion resistance of the pipeline, the current metal pipeline is usually provided with a corrosion-resistant coating on the outer wall of the pipeline to protect the pipeline. Therefore, if the pipeline is directly buried, the coating on the pipeline will be damaged, causing the pipeline corrosion to worsen.

[0004] The existing Chinese patent with the announcement number CN218598988U discloses a pipeline protection structure for trench backfilling, including a soil layer, a groove is provided on the upper side of the soil layer, and rammed layers on both sides of the pipeline are provided in the middle of the bottom of the groove, and the rammed layers on both sides of the pipeline are fixedly connected to the soil layer. Semi-circular steel molds are provided on the top of the rammed layers on both sides of the pipeline, and the semi-circular steel molds include positioning holes, a first limiting block and a half steel pipe. A half steel pipe is provided in the middle of the top of the rammed layers on both sides of the pipeline.

[0005] In view of the above and existing related technologies, the inventors believe that the following defects often exist: the length of the semi-steel pipe of the device cannot be adjusted, and it is not suitable for compacting pipes of different lengths, and needs to be improved; therefore, a pipeline protection structure for trench backfilling is proposed to address the above problems.

[0025] See also Figure 1-5 As shown, a pipe protection structure for trench backfilling includes several bases 1 and several semi-steel pipes 2. A support assembly 3 is installed above the base 1, and the support assembly 3 includes two support frames 31. The support frame 31 is set to be U-shaped, and the support frame 31 is fixedly installed on the top of the base 1. Several fixing ports 4 are opened at the bottom of the base 1. Handles 6 are fixedly connected to both sides of the top of the semi-steel pipe 2. A connecting assembly 7 is installed on the semi-steel pipe 2. The connecting assembly 7 includes several fixing seats 1 71 and fixing seats 2 72. The fixing seats 1 71 and the fixing seats 2 72 are symmetrically fixed on both sides of the semi-steel pipe 2. The construction workers hold the handle 6 to facilitate the movement of the semi-steel pipe 2, and the positioning pins 73 are installed inside the connecting port 74 to connect the adjacent semi-steel pipes 2. Compared with the existing technology, the length of the semi-steel pipe 2 can be flexibly adjusted, which is suitable for the compaction of pipes of different lengths.

[0026] A positioning pin 73 is threadedly connected to the surface of the fixing seat 1 71 .

[0027] A connection opening 74 is formed on the surface of the second fixing seat 72 by tapping.

[0028] A support seat 32 is slidably connected to the top of the support frame 31, and a threaded rotary rod 33 is threadedly connected to the top center of the support frame 31, and the bottom end of the threaded rotary rod 33 is rotatably connected to the support seat 32. By rotating the threaded rotary rod 33, the support seat 32 can be driven up and down, thereby adjusting the installation height of the semi-steel pipe 2.

[0029] The side wall of the support seat 32 is fixedly connected with a raised layer 34, and the surface of the raised layer 34 is fixedly connected with a bolt 35, and a threaded ring 36 is threadedly connected to the bolt 35. The handle 6 is placed on the raised layer 34, and the bolt 35 is passed through the positioning port 37 to connect with the threaded ring 36 to support and fix the semi-steel pipe 2. Then, through filler and mechanical tamping, the semi-steel pipe 2 is finally taken out and the pipe is arranged in the groove formed by the semi-steel pipe 2 on the ground. In this way, when tamping the soil, the pipe is prevented from being affected by stress and causing damage to the pipe surface coating, effectively preventing damage to the pipe coating, and at the same time, the pipe will not be damaged during the tamping of the filler.

[0030] The support assembly 3 further includes a positioning opening 37 , which is opened at the top of the handle 6 .

[0031] A triangular support frame 5 is fixedly connected to the side wall of the base 1 .

[0032] Working principle: the construction worker holds the handle 6 to facilitate the movement of the half steel pipe 2, and by installing the positioning pin 73 inside the connecting port 74, the adjacent half steel pipes 2 are connected, and the length of the half steel pipe 2 can be flexibly adjusted, which is suitable for the tamping of pipes of different lengths;

[0033] Place the handle 6 on the raised layer 34, and support and fix the semi-steel pipe 2 by connecting it with the bolt ring 35 and the threaded ring 36, then fill it with water and tamp it mechanically, and finally take out the semi-steel pipe 2 and arrange the pipe in the groove formed by the semi-steel pipe 2 on the ground. In this way, when tamping the soil, the pipe is prevented from being affected by stress and causing damage to the pipe surface coating, effectively preventing damage to the pipe coating, and at the same time, the pipe will not be damaged during the tamping of the filler. By rotating the threaded rotary rod 33, the support seat 32 can be driven up and down, thereby adjusting the installation height of the semi-steel pipe 2.
