Description

Technical Field

[0001] The utility model relates to the technical field of municipal thermal engineering, in particular to a municipal thermal pipe trench protection device. Background Art

[0002] The laying of thermal pipes is generally divided into two methods: underground laying and overhead laying. Overhead laying uses brackets to support the insulation pipes. For construction areas without overhead laying conditions, underground laying is usually adopted. For underground laying of insulation pipes, it is necessary to dig a trench on the ground, and then conduct pressure testing and backfilling after laying the pipes in the trench. Before backfilling, the trench needs to be protected to prevent pedestrians or vehicles from falling in.

[0003] The existing patent publication number is CN220118813U, which discloses a pipe trench protection device for municipal thermal engineering, including a pipe trench, and the left and right side walls of the top of the pipe trench are both provided with protective plates, and a cover plate is movably connected between the two protective plates; the lower surface of the cover plate is hinged to a support mechanism, and the bottom end of the support mechanism is fixedly connected to a buffer block; the protective plate is L-shaped, and its top is fastened to the soil through ground nails. The protective plate can be connected to the soil by passing through the ground nails, and the cover plate is slidably connected to the protective plate through the support mechanism. The left and right side walls of the cover plate overlap the tongue and groove. The cover plate can be tightly connected to the protective plate under the support of the support mechanism and the limiting action of the tongue and groove, thereby enhancing the protection effect, and the operation is convenient and fast, saving time and effort. The support mechanism and the protective plate can effectively protect the pipe trench and avoid soil collapse.

[0004] When installing existing municipal thermal pipelines, they are usually installed in trenches. However, when installing existing pipelines, protective devices are usually installed on the outside of the pipelines to protect the pipelines. However, when installing the pipelines, the existing protective devices do not clamp and limit the pipeline surface, resulting in shaking of the pipelines, thereby reducing the protective effect of the pipelines. To this end, we propose a municipal thermal pipeline trench protective device to solve the above-mentioned problems. Utility Model Content
