Description
Technical Field
The utility model belongs to the technical field of circulating water pipeline construction and specifically relates to a major diameter long tube section circulating water pipeline wears to adorn appurtenance.
Background
In special areas such as collapsible loess, expansive soil and the like, according to the current design specifications, a steel outer sleeve and an inspection well are required to be arranged for a buried pipeline within 5 meters of a building foundation. In a certain refuse incineration power generation construction project, two
The underground circulating water pipelines are respectively arranged at the main plant section
The inspection well comprises a steel outer sleeve and four inspection wells, wherein the lengths of the steel outer sleeve between the inspection wells are 42 meters, 42 meters and 30 meters respectively.
Two common construction methods are provided for the large-diameter long-pipe-section circulating water pipeline to be provided with the steel outer sleeve in a penetrating manner, wherein the common method comprises the following steps: firstly, respectively combining a circulating water pipeline and a steel outer sleeve on the ground, then dragging the circulating water pipeline into the steel outer sleeve by adopting a crane and a winch, and finally lifting and hanging by adopting two cranes to put the circulating water pipeline with the steel outer sleeve into position. The method has the following disadvantages: the circulating water pipeline is penetrated and installed with a steel outer sleeve in a large area, namely the length of the combined circulating water pipeline plus the steel outer sleeve is the sum of the length of the steel outer sleeve and the length of the combined circulating water pipeline; the second disadvantage is that: when the circulating water pipeline drags into the steel outer sleeve, the outer anticorrosive coating of the circulating water pipeline is very easy to damage, and the damage cannot be compensated and prevented; the third disadvantage is that: the circulating water pipeline penetrating the steel outer sleeve is long in length and heavy in weight, two cranes are required to lift and hang when the steel outer sleeve is put into place, the machine cost and the construction cost are increased, and the double-crane lifting and hanging belongs to a construction project with high risk, so that the safety risk is increased.
A second common method comprises the following steps: firstly, respectively combining a circulating water pipeline and a steel outer sleeve on the ground, then hoisting the steel outer sleeve to a sewer in place by a crane, hoisting the circulating water pipeline to the sewer by the crane, and dragging the circulating water pipeline into the steel outer sleeve by matching with a winch. The method has the following disadvantages: the winch is not easy to arrange in the circulating water pipe ditch, and the ground anchor has larger difficulty in arrangement; the second disadvantage is that: when the circulating water pipeline drags into the steel outer sleeve, the outer anticorrosive coating of the circulating water pipeline is very easy to damage, and the damage cannot be compensated and prevented; the third disadvantage is that: the circulating water pipe ditch needs to overbreak the working surface of the sewer of the long pipe section circulating water pipeline formed by combination at the penetrating side, thus increasing the construction cost. From the analysis, it can be seen that the two common construction methods for the circulating water pipeline to wear the steel outer sleeve have the disadvantages of high construction difficulty, high construction cost and high safety risk; meanwhile, the outer anticorrosive layer of the circulating water pipeline is extremely easy to damage in the wearing process, and the damage cannot be compensated and prevented, so that the construction quality cannot be guaranteed, and a large quality hidden danger is left.
