Summary of the invention
For the deficiencies in the prior art, the utility model provide a kind of do not need back, pressure testing device simple, can utilize the water inlet of single water source, can realize the heavy caliber spigot-and-socket pressure pipeline water test unit of while pressure testing and continuous pressure testing.This device can shorten the pressure testing duration significantly, reduces equipment investment cost, solves the problem of pressure testing pipeline section pressure testing water scarcity simultaneously, saves engineering water consumption.
The technical solution adopted in the utility model is: a kind of heavy caliber spigot-and-socket pressure pipeline water test unit, this device is arranged between two sections of adjacent spigot-and-socket pressure pipelines, it is characterized in that: this apparatus structure comprises steel pipe main body, described steel pipe main body two ends are connected with spigot-and-socket pressure pipeline respectively, the inner chamber of steel pipe main body is provided with steel closure plate, the tube wall bottom of the steel pipe main body of steel closure plate both sides is respectively equipped with the connecting pipe communicating with steel pipe body interior, between two described connecting pipes, be parallel with two branch roads, on the first branch road, valve is installed, on the second branch road, force (forcing) pump is installed, in force (forcing) pump both sides, be respectively equipped with valve.
Described steel pipe main body and inner steel closure plate and pressure testing pier thereof, be used to replace the back in traditional Pressure test program the water pressure while utilizing the pressure testing of pressure testing pier supporting flue.Described connecting pipe is communicated with the adjacent pressure testing section being separated by steel closure plate, and between connecting pipe two branch roads in parallel, difference mounted valve and force (forcing) pump, such design can complete after pressure testing in a pressure testing section, by connecting pipe, give the water filling of adjacent pressure testing pipeline section, and utilize force (forcing) pump to pressurize to adjacent pressure testing pipeline section, thus realize continuous pressure testing test, can also significantly reduce the water consumption of engineering like this.Utilize force (forcing) pump also can to adjacent tubular segments, carry out while applied voltage test simultaneously.In addition, because adjacent pressure testing pipeline section is communicated with by connecting pipe, so can realize the water inlet of single water source, avoided there is no enough water sources near pressure testing pipeline section and the situation that affects test.
In order to facilitate the closure plate in workman's installation and removal steel pipe main body, at steel pipe main body top, be provided with manhole, on manhole device, be provided with vent valve, for discharge gas in pipelines before pressure testing test.
In order to facilitate mounted valve, on the first branch road of connecting pipe, be connected with flexible force transmission joint.
On the connecting pipe being directly connected with adjacent test section, tensimeter is set respectively, so that read force value in pressure testing test.
In pressure testing test, the utility model adopts and in pressure testing section, pressure testing pier is set and fixes pressure testing pipeline, and pressure testing pier is arranged on upstream or the downstream of steel pipe main body, and steel pipe main body is vertically through pressure testing pier, and is connected with spigot-and-socket pressure pipeline.Described pressure testing pier can double as Mountain Area pipeline thrust pier or anchor block.
The utility model has the advantage of: do not need subsection setup back and associated machines, saved engineering cost and engineering time.The steel pipe of the hydraulic testing can be used as the ingredient of aqueduct, only need to after pressure testing, remove ducted closure plate can be communicated with, and do not need with linkage section, the adjacent tubular segments of being separated by back to be communicated with again, avoided because engineering test has been simplified in the leakage that middle linkage section causes greatly.Utilize the single water source to supply water, solved the problem that pressure testing pipeline section in the wild lacks water source.Can realize the continuous pressure testing of adjacent tubular segments, pressure testing simultaneously, obviously increase the efficiency of the hydraulic testing, save engineering water consumption.Pressure testing pier does not need to remove, and doubles as pipeline thrust pier or anchor block, plays the effect of stablizing pipeline in engineering operation.
