Description
Technical Field
The invention relates to a vertical jacking platform, in particular to a vertical jacking platform for vertically jacking pipe joints and splicing under the working condition of a small-diameter pipeline.
Background
With the further improvement of the national requirements for environmental protection, industrial wastewater and urban domestic sewage in coastal regions need to be discharged in deep sea, and the sewage discharge effect of long-distance pipelines is increasingly obvious. The sewage pipeline is paved by adopting the conventional process of excavating buried pipes underwater, and the defects of high manufacturing cost, large pollution and large environmental influence are overcome; and the pipe jacking process and the vertical jacking process are adopted, so that the damage to the environment can be effectively reduced, and meanwhile, the construction cost is lower compared with that of the underwater pipe burying process. In order to overcome the difficulty that the joints of the vertical jacking pipe joints are too many and the subsequent pipe joints cannot be smoothly spliced due to deflection under the working condition in the small-caliber pipeline, the platform for vertical jacking needs to be improved and researched again.
The conventional vertical jacking adopts a jack to act on jacking iron, and then acts on a jacking pipe joint through the jacking iron. The disadvantage is that the jack is concentrated, the length of the jacking pipe joint is short, and the electric welding joints of the pipe joint are too much; meanwhile, when the pipe joints are inclined, the subsequent pipe joints are difficult to splice and electric weld, and great influence is caused on subsequent normal vertical jacking construction.
Disclosure of Invention
The invention provides a vertical jacking platform which is used for solving the problem that a subsequent pipe joint cannot be smoothly spliced due to deflection caused by excessive vertical jacking pipe joint under the working condition of a small-caliber pipeline.
In order to realize the purpose, the technical scheme of the invention is as follows: the utility model provides a vertical jacking platform, includes jack, jacking platform, bed plate, the jack passes through the bed plate to be installed in the horizontal pipeline of small bore, jacking platform arranges the jack in to be linked into a whole with the jack, jacking platform can be upwards together along with the jack jacking for the jacking pipe joint.
The jacks are distributed and symmetrically arranged, and the jacking platform acts on the pipe joints, so that the space can be effectively utilized, and the length of the pipe joints is increased.
When the pipe joint is inclined, the jack adjusts the jacking platform to be perpendicular to the pipe joint, and therefore smooth splicing and electric welding operation of the subsequent pipe joint is guaranteed.
The invention has the beneficial effects that:
1. the jacking platform of the invention is lifted up along with the jack, the jacking platform and the jack are connected into a whole, the jacks can be distributed and symmetrically arranged, the jacking pipe sections are placed on the jacking platform, the space is fully utilized, and the length of the pipe sections is increased, therefore, the invention has obvious technological innovation, and has obvious popularization significance for taking and draining small-caliber pipes.
2. When the pipe joints are inclined, the jack can be used for adjusting the angle of the platform, and the subsequent smooth splicing and electric welding operation of the pipe joints is ensured. The vertical jacking platform solves the problems that under the working condition of a small-caliber pipeline, the joints of the vertical jacking pipe joints are too many, and the subsequent pipe joints cannot be smoothly spliced due to deflection.
Drawings
FIG. 1 is a schematic view of the vertical jacking platform structure of the present invention;
fig. 2 is a schematic plan view of the arrangement of jacks in the vertical jacking platform.
Detailed Description
The invention is further described with reference to the following figures and examples.
As shown in fig. 1, a vertical jacking platform comprises a jack 1, a jacking platform 2 and a base plate 3, wherein the jack is installed in a small-caliber horizontal pipeline through the base plate 3, the jacking platform 2 is arranged on the jack 1 and is connected with the jack 1 into a whole, and the jacking platform 2 can lift upwards along with the jack 1 for jacking pipe joints.
As shown in fig. 2, the jacks 1 are arranged in a dispersed and symmetrical manner. When the pipe joint is inclined, the jack 1 adjusts the jacking platform 2 to be perpendicular to the pipe joint, and therefore smooth splicing and electric welding operation of the subsequent pipe joint is guaranteed.
The field construction process comprises the following steps:
in the drawing design stage, determining the maximum length of jacking pipe joints and the number of the jacking pipe joints according to the novel jacking platform;
after jacking is accomplished to a section jacking pipe joint, according to the deviation of jacking pipe joint, the formation of adjustment jack 1 is poor, ensures that jacking platform 2 and pipe joint keep perpendicular, guarantees the smooth concatenation of follow-up pipe joint, electric welding operation.
Examples of the application of the invention
The engineering is located in offshore sea area of northern gulf, the engineering entity is 1 sewage steel pipe with the outer diameter of 2000mm and the wall thickness of 22mm, the length of the sewage pipeline is 3600m, and the construction is divided into two sections (2180 m top pipe section 1+1420m top pipe section 2) for jacking. 2 open caissons are arranged as a top pipe starting well, a No. 1 open caisson is arranged on the offshore side as a starting well of a top pipe section 1, and the No. 2 open caisson is a receiving well of the top pipe section 1 and a starting well of the top pipe section 2. 29 vertical jacking pipes with the diameter of phi 500 are arranged at the tail end 400m of the top pipe section 2 and used for sewage discharge, and the jacking height of pipe joints reaches 12.5 m.
29 vertical jacking pipes are arranged in the 400m area at the tail end of the top pipe section 2, and the soil layers mainly penetrated by the jacking pipes are a medium-coarse sand layer and a silty clay layer. In the initial jacking stage, a jacking first-section pipe and a jacking platform are ensured to be in a vertical state, and then a jack starts to perform pressurization jacking; after the jacking of the first section pipe is completed, the stroke of the oil cylinder of the jack is adjusted according to the deviation condition of the first section pipe, namely the inclination of the jacking platform is adjusted, and the uniform and consistent gap between the second section pipe and the first section pipe is ensured. The vertical jacking platform solves the problems that under the working condition of a small-caliber pipeline, the joints of the vertical jacking pipe joints are too many, and the subsequent pipe joints cannot be smoothly spliced due to deflection, and brings good benefits for engineering.
