Problems solved by technology

Conventional anti-corrosion methods for concrete pipelines generally use lining PVC or rubber materials. Due to the problems that PVC and rubber materials are not tightly connected with concrete and are easy to age, after a period of operation, the lining materials will fall off, thus making the pipeline lose its anti-co

Example Embodiment

[0022]Example 1:

[0023] The novel reinforced concrete drainage pipe material of the present embodiment is prepared by the following method, and the method comprises the following steps:

[0024] a. The production of reinforced concrete drainage pipes: Reactive Powder Concrete (RPC) is used as the raw material, and the specific ingredients of the reactive powder concrete are cement: sand: quartz powder: silica fume according to the mass ratio 2: 0.5: 0.32: 0.15 , the amount of water reducing agent is 2% of the total mass of cement, sand, quartz powder and silica fume, the length of steel fiber is 3-13mm, the diameter is 0.15-0.20mm, the volume dosage is 1%, and the water-binder ratio is 0.18. Use this raw material to make drainage pipes according to conventional methods. The compressive strength of RPC concrete with this optimal mass ratio can reach 150Mpa, while the thickness of the pipe wall can be reduced to about half of the conventional pipe, and the weight can be reduce...

Abstract

The invention discloses a novel reinforced concrete drainage pipe and a manufacturing method thereof. For the existing problem in the reinforced concrete drainage pipeline, the invention provides the key technology for manufacturing a novel reinforced concrete pipe in the following three aspects that: a novel anti-corrosion measure and a port type are used against the environmental factors to improve durability of the pipeline and tightness of the port; with regard to the pipeline itself, formulation of reactive powder concrete (RPC) suited for a drainage pipe is employed as the raw material, so that the strength is higher, the stability is better and the structure is more compact to block the possibly formed permeation passage; and the pipe is cheaper and lighter. The method fundamentally improves the basic performance of the reinforced concrete drainage pipeline. Due to the reduced weight and tighter port, the standard length (2.5 m) of the drainage pipeline is lengthened to 4-6 m.

Description

Technical field: [0001] The invention belongs to the field of water supply and drainage engineering and water conservancy engineering, and in particular relates to a novel reinforced concrete drainage pipe and a manufacturing method thereof. Background technique: [0002] Concrete drainage pipes laid underground for a long time are generally used well, and the cost of the pipe itself is very low. However, due to the heavy weight of the pipe, it is difficult to transport and install, and the requirements for the foundation are relatively high (concrete foundation is often used), so the overall cost is not high. Low, and when there are corrosive media inside or outside, corrosion damage will occur, resulting in a decrease in structural strength, failing to meet the requirements of the service life, resulting in waste of energy and resources. In recent years, due to the lack of tightness of the interface of the drainage pipeline, the ground subsidence accidents caused by the le...
