Underground pipe gallery pipeline made from low-cost composite material

Abstract

The invention discloses an underground pipe gallery pipeline made from a low-cost high-performance composite material and belongs to the field of constructional engineering. Specifically, water supply, water recycle, drainage, heat supply and fuel gas composite material pipelines of an underground pipe gallery are manufactured at a super-low cost. According to each pipeline, a pipeline inner layeris formed in the mode that continuous basalt fibers wind an inner core mold, a pipeline middle layer is formed in the mode that a large number of super-fine basalt fibers coat the outer surface of the pipeline inner layer, the continuous basalt fibers wind the exterior of the pipeline middle layer to achieve pipeline formation, after pipeline formation, an outer mold covers the pipeline for pressurization, and heat preservation and shape setting are conducted to complete pipe manufacturing. The pipeline made from the low-cost high-performance composite material is simple in manufacturing technology and low in manufacturing cost, the tensile strength and compressive strength of the pipeline are higher than those of pipelines made from steel and plastic composite materials, after use, the application cost of the underground pipe gallery is greatly lowered, and the service life of the underground pipe gallery pipeline is greatly prolonged.

Description

technical field [0001] The invention relates to the field of underground construction engineering, in particular to a composite material pipe for water supply, drainage, heat supply and gas in an underground pipe gallery. Background technique [0002] The underground pipe corridor is a comprehensive corridor for the comprehensive management and operation of various underground pipelines in the city. It integrates all pipeline facilities such as water supply, drainage, heating, gas, electricity, and communication, and sets up special inspection and maintenance channels. If designed and adopted The raw materials are reasonable, which can effectively reduce the cost of urban comprehensive operation and management. [0003] At present, steel and plastic glass fiber materials are generally used for underground pipe gallery pipes. Due to the problems of easy corrosion, short service life and low strength of steel pipes, plastic glass fiber pipes have poor fatigue resistance, low c...

AI Technical Summary

Problems solved by technology

[0003] At present, steel and plastic glass fiber materials are generally used for underground pipe gallery pipes. Due to the problems of easy corrosion, short service life and low strength of steel pipes, plastic glass fiber pipes have poor fatigue resistance, low creep strength, and corrosion resistance. Problems such as poor performance, difficulty in recycling, and pollution have led to the design service life of the current underground pipe gallery for 80 years. If it is scrapped and replaced when it expires, dismantling and rebuilding the pipe gallery is equivalent to double reinvestment, which will cause huge capital, manpower, material resources, and the environment. The unbearable pressure of cost will bring great economic loss to the society

If it is used for an extended period of time, the water, electricity, gas, heating, and communication integrated in each city will inevitably be paralyzed, the loss of funds will be greater, and the demolition and reconstruction period will be longer, which will cause the city to fail to operate normally during the demolition and reconstruction period, and will seriously affect People's normal production and life
