Specific embodiment
In order that the object, technical solutions and advantages of the present invention become more apparent, below in conjunction with drawings and Examples pair
Inventive pipeline laying method and device are further elaborated.It should be understood that specific embodiment described herein is only
In order to explain the present invention, it is not intended to limit the present invention.
In one embodiment, as shown in Figure 1, there is provided a kind of pipe laying method, specific the method includes following
Step：
Step 100, surveying setting-out, and execute excavation pit.
In the present embodiment, carry out job site surveying setting-out according to being pre-designed drawing.Specifically, put according to measurement center line
Go out excavating sideline, with excavator stage excavation to designed elevation, every layer height is less than 50cm.On-site concrete pipeline is carried out
Quality examination, that is, have or not dew stone, dew muscle, arrisdefect, play drum, crackle etc..Socket work surface tolerance+2mm, bellmouth work surface is straight
Footpath tolerance -1mm-+2mm.Rubber seal must not have pore, crack peeling and seam, shore hardness 45-55 degree, breaks
Intensity 16MPa, percentage elongation 500%.
Further, execution excavation pit specifically includes：Foundation trench excavates and will ensure the every side of pipe socket external wall construction width
70-80cm, bottom of trench is pressed design requirement and is tamped, and dry density 1.65g/cm3 paves 3：7 dirt, every layer of paving thickness 20-25cm,
Rammed using ramming machine and press 3-5 time, compacting factor>0.95, dirt layer surface flatness allowable error ± 50mm.
Step 200, based on pipeline foundation levelling bullet center line, checks pipeline quality, execution down tube operation.Wherein, down tube and
Comb, lays steel truss mounted track, spelling steel truss, 15-20cm more than clear span every side than pipe socket outer wall in steel truss, and pipeline
The levelling bullet center line in basis, and dig out working pit by duct length, then with truck crane, the pipeline being transported to limes marginis is put in ditch Cao,
Arrange, by pipe centerline symmetrical laying pipeline.
Step 300, spelling steel truss crane, and its pipe both sides jack is installed, complete to lift by crane pipe operations to be installed.Its
