Pressure-resistant culvert pipe with small section and circumferential stress and preparation process thereof

Abstract

The invention relates to a small-section circle stress anti-vibration culvert pipe and relative producing method. Wherein, it comprises a concrete culvert pipe, and the inner and outer skeletons inside the culvert pipe. The inner skeleton is fixed with longitudinal tube cylinder which is fixed with rotational positive cylinder tube, while the longitudinal cylinder tube of inner one has steel twisted whose one end is fixed and another end generates pre-stress; the positive cylinder tube has the steel twisted wire for generating continuous pre-stress; the inner wall has the auxiliary-drawing anchor connected to the steel twisted wire with positive rotational cylinder tube. The invention has lower cost, high efficiency and wider application.

Description

technical field [0001] The invention relates to a small cross-section annular stress-resistant compression culvert and a preparation process thereof. technical background [0002] At present, the construction methods of small-scale water conveyance culverts through mountains in China still use small-scale shield machines, and most of them are still at the level of the 1970s and 1980s. The traditional process of pouring arched culverts, so small water delivery culverts are often blocked. Simple water delivery culverts in individual areas have complex geological structures, and the active rock formations in the culverts contain hazardous substances, which cannot be controlled, often causing water pollution, which in turn endangers People's physical and mental health, most small tunnels use traditional construction methods and simple construction methods to pour concrete arched culverts, which have disadvantages such as large amount of engineering, high cost, low efficiency, sh...

Problems solved by technology

[0002] At present, the construction methods of small-scale water conveyance culverts through mountains in China are still a small number of small-scale shield machine technology, most of which are still at the level of the 1970s and 1980s. The traditional process of pouring arched culverts, so small water delivery culverts are often blocked. Simple water delivery culverts in individual areas have complex geological structures and active rock formations in culverts contain hazardous substances, which cannot be controlled, often causing water pollution, which in turn endangers People's physical and mental health, most of the small tunnels use traditional construction methods and simple construction methods to pour concrete arch culverts, which have disadvantages such as large amount of engineering, high cost, low efficiency, short life, and poor use effect. Adapt to the needs of modern water diversion engineering and road traffic construction
