Reinforced bar glass fiber resin concrete pipe and producing method thereof

Abstract

The invention discloses a reinforcement fiberglass resin concrete tube used for burying and a production method thereof, aiming at providing a reinforcement fiberglass resin concrete tube used for burying and a production method thereof with the advantages of corrosion resistance, high intensity, small resistance, low manufacture and use cost, simple manufacture technique and convenient construction. The reinforcement fiberglass resin concrete tube comprises a circular tube cast by the concrete composed by unsaturated resin and quartz sand; and connecting ports which are mutually inserted are manufactured at the two ends of the circular tube. The invention is characterized in that a tubular reinforcement mat is arranged in the circumferential wall of the circular tube; and the concrete comprises fiberglass. The production method thereof is as follows: manufacturing the reinforcement mat, diefilling, dosing, mixing, casting, solidifying, demoulding, correcting, and warehouse-in inspection. The reinforcement fiberglass resin concrete tube a lower cost than a steel tube, can not generate rustiness, and has longer service life compared with the steel tube. The mutual connection is not welded; moreover, the reinforcement fiberglass resin concrete tube is a burying jacking perfusion tube which can be broadly applied to a drinking tube or a drainage tube with the advantages of high intensity, low cost, safety and sanitation and convenient construction.

Description

technical field [0001] The invention relates to a conveying pipeline for liquid, in particular to a reinforced glass fiber resin concrete pipe buried underground and used in a water supply and drainage system and a production method thereof. Background technique [0002] In order to lay water supply and drainage pipes underground and reduce damage to ground facilities, the modern construction method is to use a pipe jacking machine to push a section of water delivery pipe forward underground and then lay it. Although this construction method does not damage the surface, it does The strength requirement of the water delivery pipe used for jacking is very high, and steel pipe is usually used, but in order to prevent the steel pipe from rusting, anti-rust treatment must be carried out on the inner and outer surfaces of the steel pipe, such as painting, etc., and the use cost of the steel pipe is high. A section of steel pipe needs to be welded, and the construction is cumbersom...

[0002] In order to lay water supply and drainage pipes underground and reduce damage to ground facilities, the modern construction method is to use a pipe jacking machine to push a section of water delivery pipe forward underground and then lay it. Although this construction method does not damage the surface, it does The strength requirement of the water delivery pipe used for jacking is very high, and steel pipe is usually used, but in order to prevent the steel pipe from rusting, anti-rust treatment must be carried out on the inner and outer surfaces of the steel pipe, such as painting, etc., and the use cost of the steel pipe is high. A section of steel pipe needs to be welded, the construction is troublesome, the cycle is long, and the laying direction of the pipe must be a straight line

Steel pipes will rust and pollute water quality after being used for a long time

Although there are fiberglass concrete composite pipes or resin concrete pipes that will not rust, they have low strength and cannot be used for pipe jacking operations
