Longitudinally spaced on foundation ditch 2 bottom surface outside long strip footing 4 multiple rows of isolated footing 7 is set, pour into a mould elongated strip footing and
While isolated footing, at elongated strip footing and top, isolated footing pre-embedded steel slab embedded part 5；
(3) along wearing the horizontal side that direction is identical with pipe curtain in described elongated strip footing 4 with the steel plate embedded part 5 of isolated footing
To welding many foundation end I-steel 8；
(4) the bottom I-steel 8 in described elongated strip footing 4 tightens tube curtain two ends and is respectively welded double-channel door shape I-shaped steel framework
Frame 6；
(5) between many foundation end I-steel 8, multiple rows of longitudinally disposed connection I-steel is welded in lateral separation, as it can be seen, can
Think that first row connects I-steel 9, second row connects I-steel 10 and the 3rd row connects I-steel 16.
(6) longitudinally spaced welding multiple ladder shape support on I-steel is connected two rows near elongated strip footing 4, such as figure institute
Showing, each ladder shape support includes that being respectively welded at first row connects first on I-steel 9 and second row connection I-steel 10
Vertical I-steel 11 and the second vertical I-steel 12, along horizontal between the first vertical I-steel 11 and the second vertical I-steel 12
Middle first I-steel 13, middle second I-steel 14 and top I-steel 15 is had to the connection being spaced up and down；
(7) the vertical bar of each ladder shape stent outer and between the connection I-steel of ladder shape stent outer along tiltedly
To welding oblique I-steel 17；
(8) in vertical bar and oblique I-steel 17 and the bottom being positioned at ladder shape stent outer of each ladder shape stent outer
The steelframe 18 of triangle is installed between I-steel 8；
(9) it is positioned in multiple transverse bar member of sustained height along longitudinally mounted I-steel 20 at multiple ladder shape supports, described
Slide rail is transversely installed on I-steel 20, described slide rail is installed push-bench pedestal 19.
Employing this method has been constructed after back device, installs push-bench 22, pacify in push-bench jack-in process on push-bench pedestal 19
Complete stable, there is no sinking and the rising phenomenon of generator tube curtain steel pipe, the most do not occur ground settlement excessive or work surface collapses the thing such as collapse
Therefore.Ensure that the safe operation of pipeline above push-bench in construction, jacking front is when running into the relatively barrier such as cobble stone, boulder, boulder
The bearing capacity of back device is the most safe and reliable, ensure that the properly functioning of road traffic simultaneously.
