Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage pipeline protection, in particular to a water supply and drainage pipeline protection device for building and municipal road construction. Background Art

[0002] Water supply and drainage pipes are often used in construction sites of municipal roads, mainly for transporting domestic sewage or industrial wastewater. During the transportation process, the water supply and drainage pipes are easily affected by temperature changes in the area and undergo thermal expansion and contraction, resulting in greater stress on the water supply and drainage pipes and possible large vibrations or even rupture of the water supply and drainage pipes.

[0003] A Chinese patent application CN201620658545.6 discloses a water supply and drainage pipeline. The key points of its technical solution are: the utility model has a simple structure and is easy to use. The sound insulation holes and noise reduction ribs arranged inside the inner pipe play a role in silencing and reducing noise; the thermal insulation layer adopts a polyurethane foam material layer to achieve a good thermal insulation effect. The utility model is also equipped with water retaining blocks at different positions. When the pressure in the pipeline is relatively low, the water flow touches the water retaining block, and the water flow is diverted or generates waves, which can wash the sediment sludge and other solid waste in the pipeline itself. The auxiliary nozzle on the pipeline is connected to the external pressure water pipe, which can spray high-pressure water to perform high-pressure flushing in the pipeline to make the pipeline unobstructed, complete automatic sludge discharge, and prevent blockage, which is suitable for large-scale promotion.

[0004] With respect to the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: when water pipes are carrying out water supply or drainage operations, if the temperature in the area changes greatly, the water pipes may expand and contract due to heat, so that when the water pipes under the road are constrained and cannot expand and contract freely, large stress will be generated inside the pipes, resulting in the water pipes being unable to withstand the large stress and suffering damage such as cracks and ruptures; therefore, in response to the above-mentioned problems, a water supply and drainage pipe protection device for building and municipal road construction is proposed. Utility Model Content

A water supply and drainage pipe protection device for building and municipal road construction is proposed.

[0006] In order to achieve the above-mentioned object, the utility model adopts the following technical scheme: A water supply and drainage pipe protection device for construction and municipal road construction, comprising a water pipe, a protective device being provided on the arc surface of the water pipe, the protective device comprising an upper soft pad, the upper soft pad being slidably connected to the arc surface of the water pipe, the arc surface of the upper soft pad being fixedly connected to an upper connecting block, the arc surface of the upper connecting block being fixedly connected to a first spring, one end of the first spring away from the upper connecting block being fixedly connected to an upper circular ring warehouse, one end of the upper circular ring warehouse being fixedly connected to an upper circular pad, the arc surface of the upper circular pad being fixedly connected to an upper arc shell, the arc surface of the water pipe being slidably connected to a lower soft pad, the arc surface of the lower soft pad being fixedly connected to a lower connecting block, the arc surface of the lower connecting block being fixedly connected to a second spring, one end of the second spring away from the lower connecting block being fixedly connected to a lower circular ring warehouse, one end of the lower circular ring warehouse being fixedly connected to a lower circular pad, the arc surface of the lower circular pad being fixedly connected to a lower arc shell, and the upper arc shell being slidably connected to the surface of the lower arc shell.

The threaded rod can also be rotated to drive the arc block away from the arc groove of the installation block, and the upper arc shell and the lower arc shell can be quickly disassembled, thereby driving the disassembly of the protective device, making it convenient for the staff to observe, repair or other operations on the water pipe.

[0016] Preferably, a limiting rod is slidably inserted into the fixing frame, and one end of the limiting rod is fixedly connected to the arc block.

[0017] The effects achieved by the above components are: avoiding the situation in which the arc block rotates as the threaded rod rotates when the worker rotates the threaded rod, thereby improving the stability of the device.

[0018] Preferably, one end of the threaded rod is fixedly connected to a rotating handle, and the fixing frame is U-shaped.
