Prefabricated cable duct bank and construction method thereof

Abstract

The invention discloses a prefabricated cable duct bank and a construction method thereof. The prefabricated cable duct bank comprises at least two layers of plate-type prefabricated concrete members, each layer of plate-type prefabricated concrete member is formed by splicing a plurality of plate-type prefabricated concrete members which are in butt joint in the length direction, during construction, the first layer of plate-type prefabricated concrete member is hoisted firstly and gently falls to a positioning position, and the plate-type prefabricated concrete members are connected and glued by using pipe joint sleeves; then, the second layer of plate-type prefabricated concrete member is hoisted, the adjacent upper and lower layers of plate-type prefabricated concrete members are in staggered lap joint and are fastened and connected through bolts, and the end parts of protection pipe joints in the two adjacent plate-type prefabricated concrete members are connected through pipe joint sleeves in an adhesive manner; and in the same way, the other multiple layers of plate-type prefabricated concrete members are laid in sequence. The prefabricated cable duct bank is convenient to construct, good in integrity, high in stability and good in waterproof and anti-erosion effect, noise pollution and environmental influence of field operation are reduced, the requirement for field personnel is reduced, and cost is greatly saved.

Description

technical field [0001] The invention relates to electric power pipeline technology, in particular to a prefabricated cable pipe arrangement and a construction method thereof. Background technique [0002] With the development of social economy and power grid technology, overhead transmission lines are limited by landscape and path conditions, and power cables are gradually shifted from aerial erection to underground laying. [0003] The traditional cable laying, especially the laying of multiple cables, generally adopts the form of cable pipes. The foundation trench is excavated on site, the special cable pipes are laid, and then concrete is poured for curing. This traditional way of construction site excavation and material stacking occupies a large area, requires a lot of manpower, and has a large workload. The mold making is labor-intensive and time-consuming, and it is difficult to reuse. The construction period is long and the construction quality cannot be guaranteed; ...

Problems solved by technology

This traditional way of construction site excavation and material stacking occupies a large area, requires a lot of manpower, and has a large workload. The mold making is labor-intensive and time-consuming, and it is difficult to reuse. The construction period is long and the construction quality cannot be guaranteed; noise and dust are generated during construction. Pollution has a great impact on road traffic and brings inconvenience to the daily life of the public
