Problems solved by technology

At present, horizontal directional drilling technology is mostly used for high-voltage cables crossing coastal flood control. Although this technology does not require excavation of coastal breakwaters, because the final depth of riprap settlement is uncertain, the drill bit of horizontal directional drilling is very easy to touch the riprap in settlement. And the risk of damaging the pipeline when drilling fails or is pulled back is extremely high; and the cost and construction period of the horizontal directional drilling process are too long, which is not conducive to shortening the project period. Therefore, the technical solution of the present invention is proposed to solve the problem of crossing the breakwater. related question

Abstract

The invention relates to the technical field of power construction, and discloses a high-voltage cable channel. The high-voltage cable channel comprises a lifting pipeline, a first working well, a second working well and at least one connecting pipeline. The first working well and the second working well are connected through the connecting pipeline, one end of the lifting pipeline is connected with the first working well, and an included angle is formed between the lifting pipeline and the sea level. The first working well and the second working well each comprise a containing cavity definedby a working well bottom plate and a plurality of working well side walls and a working well cover plate arranged on the containing cavity in a covering mode, and connecting through holes are formed in the side walls connected with the connecting pipeline and the lifting pipeline. According to the technical scheme, the high-voltage cable channel is simple in structure, simple in assembly process,firm in structure and convenient to lay quickly.

Description

technical field [0001] The invention relates to the technical field of electric power construction, in particular to a high-voltage cable channel. Background technique [0002] At present, when offshore wind power is transmitted to land or land grid is transmitted to offshore drilling oil platforms, it is necessary to pass through coastal breakwaters. Most of the foundations of coastal breakwaters in my country are riprap structures, that is, the foundations of breakwaters are formed by disorganized ripraps squeezing silt and natural settlement. The structure, shape, and size of ripraps are uneven, and the final settlement of ripraps is stable. Can't be sure, that may have been settling. At present, horizontal directional drilling technology is mostly used for high-voltage cables crossing coastal flood control. Although this technology does not require excavation of coastal breakwaters, because the final depth of riprap settlement is uncertain, the drill bit of horizontal di...
