Description
Technical Field
The utility model belongs to the technical field of civil engineering of electric power facilities, and particularly relates to a working well end section for an assembled cable channel.
Background
With the development of production construction and the improvement of living standard of people, the utilization of electric energy by industrial production processes in various fields and the life of people is very popular, the electric energy needs to pass through the processes of power transmission, power transformation, power distribution and the like from a power plant to users, and a power line is a conductor loop which connects a power transformation station and a power distribution station with each electric energy user or electric equipment and transmits and distributes the electric energy to a load end (the electric energy user or the electric equipment) from the power supply end (the power transformation station and the power distribution station). The power line mainly comprises an overhead line and a cable line; the cable line is laid in the power channel, and common outdoor cable laying modes comprise underground direct-buried laying, protective pipe penetrating laying, cable trench laying and cable tunnel laying; working wells are generally arranged at the intersection, the turning, the pipe diameter or gradient change position of the cable channel and at the position of the straight channel at certain intervals, so that the cable channel is convenient for threading construction, periodic inspection and maintenance. The traditional power channel working well adopts brick masonry or cast-in-place plain concrete, but with the development of the electric power industry in China, the requirements on energy conservation and environmental protection are higher and higher, and the construction requirements of the national power grid company on the distribution line are executed according to the two-type standard, namely environment-friendly type, resource-saving type and industrialization. At the present stage, the fabricated prefabricated parts are actively researched in various places to meet the construction requirements of power channels under new requirements.
Compared with a cast-in-place power channel, the assembly type power channel has the following advantages: (1) the construction period is short: taking a high-voltage power channel of one kilometer cast in place as an example, the high-voltage power channel needs to be excavated, bedding is constructed, an outer mold is built, an inner mold is supported, steel bars are blanked, the steel bars are bundled, concrete is poured, concrete is maintained and the mold is removed, and finally earth is backfilled, and the normal construction period needs about two months. And all processes of all prefabricated part products of the fabricated power channel are finished in a factory, and can be directly assembled after cushion layers are manufactured on site, the construction period only needs about 15 days, and the time can be shortened by about 75%. If the road occupation situation is met during the construction process, the road occupation cost and the environmental protection measure cost caused by the influence on normal traffic are greatly reduced. (2) The engineering quality is guaranteed: the power supply safety is the heaviest, in the traditional civil engineering construction process, concrete needs to be poured in situ, the influence of fields, environment and climate is large, the condition of material reduction by stealing work of concealed engineering is difficult to avoid, the construction quality is difficult to guarantee, and the condition that brick laying and plain concrete power distribution cabinet foundations used most often still have the settlement too big and lead to the fracture to take place on the soft soil foundation, buries very big hidden danger for power supply safety in the future. The product of the fabricated part is finished in a factory, complete quality control measures are provided, and the fabricated part is high in quality controllability and reliable in quality. (3) Meets the environmental protection requirement: the problems of noise, dust emission, pollution and the like in the field construction process cannot be avoided, and strict environmental protection measures are provided in the factory, so that the environmental protection problem is effectively solved. (4) The construction cost is low: for 150 cable well end sections (150 x 2000 x 650), the construction method of pouring concrete in situ is adopted, the cost is about 1480 yuan/yuan, and uncontrollable factors of long-time lane occupation can be contained; the prefabricated cable well end sections are manufactured in a factory, cushion layer excavation and hoisting, transporting and installing construction are carried out on site, the approximate calculation is about 1150 yuan/unit, the assembly type prefabricated parts are processed in the factory and produced in a production line mode, the overall cost is further lower than the cost of on-site manufacturing along with the increase of yield, the template reuse rate of the prefabricated parts is high, and the waste can be avoided.
In conclusion, the construction process of the traditional site construction mode is complicated, the construction period is long, the labor force requirement is large, the construction period is greatly influenced by the environment, the construction quality is difficult to guarantee, and the later maintenance is inconvenient.
