Abstract
The utility model discloses a shallow municipal water pipe damping device that buries, its characterized in that, this damping device include arc roof and curb plate, be connected through the welded mode between arc roof and the curb plate, be provided with the retainer plate between arc roof and the municipal water pipe, through three vertical spring bolted connection between retainer plate and the roof, municipal water pipe lower extreme is a unable adjustment base, and whole device is settled on a cement cushion cap, through expansion spring bolted fixation between both sides board and the cement cushion cap. The whole device utilizes the protective steel plate to evenly distribute the load on two sides of the water pipe, and then utilizes the compression of the spring to realize the protection of the shallow municipal water pipe. The device is simple and convenient to install, stable in performance, improves the shock resistance and the service life of the pipeline, and can play a good role in protecting shallow municipal water pipes buried in road sections with frequent shock loads such as roads and railways.
Description
Technical Field
The utility model relates to a municipal administration water pipe protection field especially relates to a shallow municipal administration water pipe damping device that buries.
Background
When important municipal water pipes are buried under roads or railways and the buried depth of the municipal water pipes is shallow, the municipal water pipes have to bear the vibration load of vehicles from the upper part and can be damaged. In order to protect these important municipal water pipes from the shock loads of the vehicle, such municipal water pipes must be protected.
SUMMERY OF THE UTILITY MODEL
A first object of the utility model is to provide a shallow municipal water pipe damping device that buries to avoid leading to the municipal water pipe because of vehicle vibrations load to destroy the loss that brings.
The utility model provides a shallow municipal water pipe damping device that buries, including arc roof and curb plate, weld between the arc roof curb plate, be provided with the retainer plate between arc roof and the municipal water pipe, through three vertical spring bolted connection between retainer plate and the arc roof, municipal water pipe lower extreme is a unable adjustment base, fill in the whole device of foam and install on a cement cushion cap between municipal water pipe and the both sides board, both sides board passes through the expanding spring bolt fastening with the cement cushion cap, the backfill top is provided with the protection steel sheet, make the even atress of pipeline, whole device utilizes the protection steel sheet to load evenly distributed in the water pipe both sides earlier, the compression of recycling spring is used for realizing above-mentioned purpose to the cushioning effect that the upper portion load produced.
Specifically, the length of the foam is 1 meter, the thickness of the protective steel plate is 1.2 cm, the thickness of the arc-shaped top plate and the thickness of the side plate are 8 mm, and the longitudinal interval of all the spring bolts is 0.2 meter.
The foam material between municipal administration water pipe and the curb plate is the EPS foam, and this foam is except the shock attenuation, still has the thermal-insulated effect of heat preservation simultaneously, can prevent that the frost crack of pipeline winter from destroying.
The sand cushion layer can have a cushioning effect on the impact load of the upper part, the damage of the device of the upper part due to the impact load is avoided, meanwhile, the sand cushion layer can also cover the stone bumps possibly appearing at the bottom of the pipe groove, after the pipeline is built, the vehicle load, the soil pressure and other relatively large loads are borne by the stone bumps, and if the sand can cover the bumps, the damage of the water pipe due to the local stress concentration can be avoided.
The protection steel sheet can be with the even distribution of road surface load in the pipeline both sides for the even atress of protection casing that arc roof and curb plate constitute also can contrast great impact load simultaneously and produce the cushioning effect.
Be provided with three spring bolt between this device arc roof and the municipal water pipe, when the municipal water pipe will receive vertical load, because the compression of spring, the device's shell can produce vertical displacement earlier than the pipeline, and the pipeline avoids vertical displacement, has reduced the possibility that the pipeline destroys.
