Abstract

The invention discloses an assembly type lightweight thin wall integrated pipe gallery and a production method thereof. The integrated pipe gallery is produced through casting molding of ultrahigh performance powdery concrete. The ultrahigh performance powdery concrete makes the integrated pipe gallery have a light structure, so various pipelines, cables, optical cables and other products can be safely laid.

Description

technical field [0001] The invention relates to municipal comprehensive pipelines, in particular to an assembled light-weight thin-wall comprehensive pipeline gallery and a preparation method thereof. Background technique [0002] The municipal comprehensive pipe gallery usually adopts ordinary concrete prefabrication or on-site pouring pipe gallery for construction. Generally, the prefabricated single unit is 2 meters long and weighs about 30~50 tons. It uses C40~C50 concrete, and the design thickness is generally 200~350mm. The construction is very cumbersome and the hoisting is very difficult. Moreover, the traditional process mainly adopts prestressing and post-tensioning for installation in place, which often causes prestressing cracks in the concrete section. The product has a large self-weight and requires high construction foundation. Otherwise, local settlement is easy to occur, resulting in brittle fracture of the interface and leakage. And other phenomena, for sa...
