Description

Technical Field

[0001] The utility model relates to the technical field of gas pipes, in particular to a pipeline crossing protection structure. Background Art

[0002] When constructing municipal drainage box culverts in areas with dense underground space in cities, due to the large number of underground pipelines and their complex layout, new structures often need to be closely coordinated with existing pipelines. In these environments, gas pipelines, as an important part of the city's energy supply, are of vital importance for their safe operation. By applying this technology, the problem of existing gas pipelines crossing and being exposed during the construction of new pipelines can be solved without interfering with the normal operation of gas pipelines, thus smoothly completing the construction of new pipelines and ensuring that the two do not affect each other in subsequent operations.

[0003] Traditional municipal pipeline construction usually focuses on the structural design and stability of the pipeline itself, while the protection of surrounding pipelines is relatively simple. Common practices may include: no special protection and foundation isolation, but during construction and use, problems such as gas pipeline damage, limited isolation effect, and poor long-term stability may occur. Therefore, in new pipeline projects, more advanced and effective pipeline protection technologies need to be adopted to ensure the smooth progress of the project and long-term safe operation. Therefore, this application proposes a pipeline cross-crossing protection structure to solve the above problems. Utility Model Content

[0006] The cam is secured to a location where the two rails are connected, and a lever is secured to a location where the two rails are pivotally connected to each other with a pin to allow the two rails to move freely in the map.

[0007] By adopting this technical solution, the filling layer and the protective tube are installed and fixed through the installation mechanism.

[0008] Furthermore, the limiting assembly includes a telescopic rod fixed to the right side of the cavity inner cavity, a second spring sleeved on the outer surface of the telescopic rod, a movable plate fixed to the left side of the telescopic rod, a third clamping rod fixed to the left side of the movable plate, two pull rods fixed to the right side of the movable plate, and a pull plate fixed to the right side of the two pull rods. A third clamping slot is provided on the right side of the movable plate.

[0009] By adopting this technical solution, the filling layer and the protective tube are installed and fixed through the installation mechanism.

[0010] Furthermore, a limiting rod is fixed on the opposite sides of the two push plates, and four limiting holes are opened on the outer surface of the mounting ring. The limiting rod is slidably connected to the inside of the limiting hole.

[0011] By adopting this technical solution, the stability of the push plate during movement is increased.

[0012] Furthermore, the first card rod slides inside the first card slot, and the second card rod is slidably connected to the inside of the second card slot.

[0013] By adopting this technical solution, the first clamping rod is clamped into the interior of the first clamping groove to fix the gas pipeline, and the second clamping rod is clamped into the interior of the second clamping groove to fix the protective tube.

[0014] Furthermore, two sliding holes are provided on the upper surface of the movable plate, and the movable plate is slidably connected to the outer surface of the fixed rod through the sliding holes.

[0015] By adopting this technical solution, the stability of the moving plate is increased during movement.

[0016] Furthermore, the opposite sides of the upper and lower first springs are fixed to the opposite sides of the two inner cavities of the mounting ring, and the opposite sides of the upper and lower first springs are fixed to the opposite sides of the two movable plates.

[0017] By adopting this technical solution, when the push plate moves away from the movable plate, the movable plate is reset by the first spring, driving the first clamping rod and the second clamping rod to move simultaneously.

[0018] Furthermore, the filling layer is expansive soil, and the protective pipe is a PE pipe.

[0019] By adopting this technical solution, the gas pipeline is protected by the filling layer and the protective pipe.

[0020] Furthermore, the third clamping rod is slidably connected to the inside of the third clamping slot, the left side of the second spring is fixed to the right side of the movable plate, and the right side of the second spring is fixed to the right side of the cavity.

[0021] By adopting this technical solution, the third card rod is clamped into the inside of the third card slot to further limit the movable plate. After the push plate is away from the movable plate, the movable plate can move freely, thereby improving the stability of the movable plate.
