Problems solved by technology

The fly ash, slag, nano-calcium carbonate and nano-silicon dioxide of this invention can react with cement hydration products to form a gel, which can be filled in the voids of concrete and improve the compactness of the concrete structure. However, the patent crushed stone and river Sand is the main component, so it is not suitable for the production of pipe corridors that require low weight and good seepage resistance

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...
