Description
Technical field
The present invention relates under a kind of vertical lifting platform, especially a kind of working condition for small-bore pipeline, vertically
Jack tube coupling and the vertical lifting platform of splicing.
Background technology
With country's further improving for environmental requirement, coastal area industrial wastewater and city domestic sewage need to carry out
Deep sea emission, long-distance pipe blowdown effect are further obvious.The technique that pipe laying is excavated using conventional subsea is laid with blow-off line, its
Drawback is cost is high, pollution is big, environment influence is big；And pipe pushing technology+vertical jacking technique is used, it can effectively reduce to environment
Destroy, meanwhile, project cost is relatively low relative to underwater pipe laying technique.To overcome under the working condition in small-bore pipeline,
The difficult point that vertical jacking tube coupling connector is excessive, causes follow-up tube coupling to can not be successfully splicing due to deflection, it is necessary to what is vertically jacked
Platform re-starts improvement, research and development.
Conventional vertical jacking acts on top iron using jack, is then acted on by pushing up iron on jacking tube coupling.Shortcoming is
Since jack compares concentration, it is shorter to jack the length of tube coupling, causes tube coupling joints made by electric welding excessive；Glanced off at the same time in tube coupling
When, cause follow-up tube coupling splicing, electric welding difficult, can make a big impact to follow-up normal upright jack-up construction.
The content of the invention
The present invention is to provide for a kind of vertical lifting platform, for solving under the working condition of small-bore pipeline, vertically
Jacking tube coupling connector is excessive, since deflection causes follow-up tube coupling to can not be successfully spelling problem with grounding.
To achieve the above object, the technical scheme is that：A kind of vertical lifting platform, including jack, jacking are put down
Platform, base board, the jack are installed in small-bore horizontal pipe by base board, and the lifting platform is placed in jack
On, and it is linked to be an entirety with jack, lifting platform can be upward together with jack jacking, for jacking tube coupling.
The jack disperses, is arranged symmetrically, and lifting platform acts on tube coupling, can efficiently use space, increase tube coupling length
Degree.
When tube coupling glances off, the jack adjustment lifting platform is vertical with tube coupling, ensures the suitable of follow-up tube coupling
Profit splicing, electric welding field.
The beneficial effects of the invention are as follows：
1st, traditional jacking technique is directly acted on tube coupling using jack, and lifting platform of the invention jacks one with jack
Rise upwards, lifting platform and jack are linked to be an entirety, can disperse jack, be arranged symmetrically, and jacking tube coupling is positioned over
Lifting platform, makes full use of space, increases tube coupling length, therefore, the present invention has obvious process innovation, and small-bore pipeline is taken
Draining has obvious dissemination.
2nd, when tube coupling glances off, platform angle is adjusted using jack, ensures smooth splicing, the electricity of follow-up tube coupling
Weld operation.The vertical lifting platform is solved under the working condition of small-bore pipeline, it is vertical jack tube coupling connector it is excessive, due to
Deflection causes follow-up tube coupling to can not be successfully spelling problem with grounding.
Brief description of the drawings
Fig. 1 is the vertical lifting platform structure diagram of the present invention；
Fig. 2 is jack plane of arrangement schematic diagram in vertical lifting platform.
Embodiment
The present invention is further illustrated with embodiment below in conjunction with the accompanying drawings.
As shown in Figure 1, a kind of vertical lifting platform, including jack 1, lifting platform 2, base board 3, jack passes through bottom
Seat board 3 is installed in small-bore horizontal pipe, and lifting platform 2 is placed on jack 1, and is linked to be an entirety with jack 1,
Lifting platform 2 can be jacked together with jack 1 upwards, for jacking tube coupling.
As shown in Fig. 2, jack 1 disperses, is arranged symmetrically.When tube coupling glances off, jack 1 adjusts lifting platform 2
It is vertical with tube coupling, ensure smooth splicing, the electric welding field of follow-up tube coupling.
Site operation flow is as follows：
In the layout design stage, according to new lifting platform, determine the maximum length of jacking tube coupling, determine to jack the number of tube coupling
Amount；
After a section jacking tube coupling completes jacking, according to the deviation of jacking tube coupling, the formation for adjusting jack 1 is poor, it is ensured that jacking
Platform 2 is vertical with tube coupling holding, ensures smooth splicing, the electric welding field of follow-up tube coupling.
Application implementation example of the present invention
Engineering is located at North Sea offshore sea waters, and engineering entity is 1 outside diameter 2000mm, the sewage steel pipe of wall thickness 22mm, sewage pipe
Road length 3600m, is divided into two sections（2180m push pipe section 1+1420m push pipes section 2）Jacking construction.2 open caissons are set as push pipe
Starting well, inshore side sets starting well of the 1# open caissons as push pipe section 1, and the received well that 2# open caissons are both push pipe section 1 is
The starting well of push pipe section 2.The vertical jacking pipe that 29 Φ 500 are disposed with the end 400m of push pipe section 2 is used for sewage discharge, manages
Section top lifting height reaches 12.5m.
For 29 vertical jacking pipes in the end 400m regions of push pipe section 2, the soil layer that jacking pipe mainly passes through is medium-sand seam
With silty clay layer.During the initial jacking stage, it is ensured that the first section pipe of jacking is in plumbness with lifting platform, then very heavy open-top
Begin to pressurize and jack；After completing first section tube top and rising, pipe deviation situation is saved according to head, adjusts the oil cylinder stroke of jack, i.e., to top
The gradient of peaceful completes adjustment, ensures that double section tube is consistent with the gap uniformity of first section pipe.The vertical lifting platform solves
Under the working condition of small-bore pipeline, it is vertical jack tube coupling connector it is excessive, since deflection causes the follow-up tube coupling to can not be successfully
Problem with grounding is spelled, good benefit is brought for engineering.
