Meanwhile, the placing plate 21 is in threaded connection with a fastening bolt 23, and the fastening bolt 23 is in threaded connection with the ground, so that the baffle plate 2 can be fixed on the ground. Fastening bolt 23 is along the direction screw in of perpendicular to placing board 21 inclined plane, reduces gradually from the one end that is close to placing board 21 to the one end that is close to ground apart from the distance of slot, and when baffle 2 slided to the direction at slot place under earth thrust effect, fastening bolt 23 born the axial force for fastening bolt 23's support intensity is higher, and baffle 2 is fixed more stable.
And step three, taking out the old pipeline.
And step four, pipeline foundation. The pipeline foundation adopts a gravel cushion foundation; for a common soil area, a layer of coarse sand foundation with the thickness of 0.1m can be paved on the substrate; when the bottom of the soft soil foundation is below the ground water level, a gravel foundation with the thickness of not less than 0.20m is preferably paved, the gravel foundation can also be paved in two layers, the lower layer is made of gravels with the particle size of 5-40mm, and the upper layer is paved with coarse sand with the thickness of not less than 0.05 m.
And step five, installing a pipeline. The pipeline can be put into the groove after being fully cooled, and the pipe is lifted up by wrapping the pipe with a rope during installation and slowly put into the bottom of the groove.
And step six, connecting pipelines. The thermoplastic plastic composite pipelines and pipe fittings are connected by adopting an electric melting socket welding mode or a pressing type mechanical connection mode.
And step seven, testing. Before the pipeline test, the system, equipment, instruments and accessories which do not participate in the test are dismantled, and short pipes or blind plates are added for isolation (and marked). The pressure in the pipeline is tested by using pressure gauges, at least 2 pressure gauges are arranged, the precision grade is 1.6 grade, and the measuring range of the pressure gauges is 1.5-2 times of the maximum pressure to be tested.
The hydraulic pressure test is carried out according to the pressure of the pipeline medium, the test is carried out by using clean water, and air is exhausted when the system is filled with water. During pressure test, low-pressure pre-inspection is firstly carried out, then the pressure is gradually increased by 10 percent for inspection, and the test pressure is 1.5 times of the design pressure. And (4) after the pressure is increased to the test pressure, stabilizing the pressure for 10min, then reducing the test pressure to the design pressure, stopping the pressure for 30min, and determining that the pressure is not reduced and has no leakage.
And step eight, purging the pipeline. After the pipeline is installed, compressed air is adopted to sweep the pipeline in sections, an oil filtering device is connected to the air compressor firstly, then the swept air compressor is connected through a temporary pipeline, and deoiling treatment can be carried out on gas blown out by the air compressor, so that the swept compressed air does not contain grease.
And step nine, backfilling and tamping the grooves. And backfilling the pipe ditch by using medium sand with the large particle size not more than 3mm until the pipe ditch is backfilled to 200-300mm above the top of the pipe, and then backfilling and compacting the pipe ditch by using original soil, wherein the backfilling of the pipe ditch is 300mm higher than the ground.
