Examination, which is hung, to be carried out on the casing rack after unpacking, slow with crane in the good hanging sleeve of two hoisting point position colligations
Sleeve pipe is lifted up, stops lifting when being promoted to apart from ground 100mm, each position of sleeve pipe, hanging sleeve is gone through, hangs
Whether tool, crane have exception, and confirm sleeve pipe keep level state when not by external force.
The lifting of the utility model sleeve pipe:
After examination is hung successfully, fastened at sleeve pipe both ends and slip rope.After sleeve pipe level is lifted to sleeve pipe reserving hole position, factory building two
Installation personnel on the platform of side coordinates crane that sleeve pipe slowly is penetrated into reserving hole while sleeve pipe is protected, while will be pre-
Box out three side built-in fitting flitch cushionings, prevent damage of being collided with when sleeve pipe passes through, prevent sleeve pipe from rocking collision.In hoisting process,
Close to wall, sleeve pipe stops suspension hook when penetrating about 3.7m.
Arrange that (porcelain patticoat of hoisting point position is filled up suspension centre with flexible material, outer layer rubber at 3.5 meters of wall bushing both ends
Wrap up and be used for protection sleeve pipe porcelain patticoat), hanging sleeve is tied up, is lifted by crane using straddle truck and whipline, it is painstaking that suspender belt is slowly promoted to
Untill, main suspension hook is unclamped, unties hanging sleeve.Then cooperated by the straddle truck and whipline of partition wall strong point both sides, will
Sleeve pipe is slowly through installation site.
The fixation of the utility model sleeve pipe:
Mounting flange and loose flange are carried on wall bushing, mounting flange, rear installation activity flange are first installed.
1st, after sleeve pipe reaches installation site, wall-penetrating partition board is arranged on mounting flange, fastening bolt, utilizes horizon rule pair
Sleeve pipe carries out horizontal alignment, and carefully adjustment level and installation dimension, is padded stationary barrier gap with parallels after reaching requirement,
And parallels, dividing plate and the built-in fitting of relevant position are welded and fixed.
2nd, the stationary barrier of installation activity flange.Bolt is first put in the bolt hole of loose flange during installation and by dividing plate
It is fixed, then the loose flange equipped with dividing plate is adjusted to installation site, stationary barrier gap is padded with parallels, and by parallels,
Dividing plate and the built-in fitting of relevant position are welded and fixed.
Sleeve pipe must be protected when the 3rd, welding, covering must not tightly damage, burn sleeve pipe.
The installation of the utility model steel pipe support
In order to strengthen the stability of wall bushing, one stable support is done with steel pipe to wall bushing in interlayer.According to
On-site actual situations determine the position of steel pipe support.
The determination of horizontal range:The centre distance of built-in fitting is 440mm in hole, and two wall faces of distance are respectively 120mm.
Due to thering is heating and various pipelines to get out of the way 300mm close to metope in interlayer, then avoid the position of sleeve pipe oil filler point and sampling valve
320mm is got out of the way again, finally determines steel pipe support point distance sleeve mounting flange 1180mm according to above-mentioned data, i.e., apart from metope
620mm。
The determination of height:Installation hole base is 4900mm apart from ground level, the horizontal centre linear distance hole of hole
Base 600mm, the radius of sleeve pipe steel cylinder part is 220mm (in-site measurement), and the height of steel pipe support is 4900+600-
220=5280mm.
Steel pipe support uses Φ 250 × 6mm steel pipes, top plate 400mm × 400mm × 10mm steel plates and steel-pipe welding;Top plate
Welding is connected upper No. 10 channel-section steels with 2 1m length with steel pipe roof bolt back-to-back;1 block of circular arc steel plate (circle is welded on channel-section steel
Arc radius 250mm) width x thickness=100 × 20mm supporting sleeves.
The fixation of steel pipe support:Because the ground in interlayer does not allow pre-embedded anchoring bolts, therefore the fixation of steel pipe support
Using top is welded and fixed using the built-in fitting of hole with steel pipe support with 50 × 5 angle steel;Middle and bottom is using on wall
Pre-buried expansion bolt is fixed with 50 × 5 angle steel with wall and steel pipe support.
Explanation:Steel pipe support does good material preparation by above-mentioned requirements, and live processing and fabricating is carried out according to actual conditions.Highly
Error fine setting utilize top channel-section steel and top plate between cushioning iron method progress.
The advantages of the utility model is:
The engineering project deadline be one month, can save for only use three day time, be company directly save expense
101250 yuan (referring to table 1):
Table 1
By everyone per day people=3750 yuan of wage 150 yuan × 25;3750 yuan × 27 days=101250 yuan.
And put into operation in advance, certain contribution is also made that for power grid construction.
Electric device installing engineering should be met after sleeve pipe installation《High-Voltage Electrical Appliances are constructed and acceptance specification》(GB50147-
2010).After the completion of construction, relevant parameter is tested, it is ensured that sleeve pipe state is intact.Taken the initiative in construction control, to critical process
Carry out stand-by supervision, the measure that emphasis is kept a close safeguard, carry out self-test, eventually reinspection, inspection in real earnest.Relevant quality standard of constructing is implemented complete
Orientation, the follow-up inspection of overall process and control, accomplish that last process is qualified without examining, next procedure construction must not be transferred to.
The utility model is effective to be:It is simple in construction, electric device installing engineering should be met after sleeve pipe installation, is shortened
In the cycle of construction, cost is saved, relevant quality standard implements comprehensive, overall process follow-up inspection and control to constructing
