A high-durability concrete drainage pipe and its production process

Abstract

The invention provides a high-durability concrete drainage pipe and its production process, comprising: a high-durability concrete drainage pipe and its production process, including a concrete drainage pipe, and the opening ends on the left and right sides of the concrete drainage pipe are sealed with buckles Connected with a group of said rubber isolation mechanism. The left and right ends of the concrete pipe body of the present invention are provided with ring-shaped nylon reserved blocks, and ring-shaped elliptical limit embedding grooves are opened on the ring-shaped nylon reserved blocks. When the concrete drain pipe is manufactured and temporarily stored, it can be Two sets of rubber isolation mechanisms are respectively sealed and buckled on the left and right sides of the concrete drain pipe, so that during daily storage, it can effectively prevent liquids such as water, animals and gravel from entering the inner end of the concrete drain pipe, thus avoiding the SBS leak-proof coil The layer is worn, damaged or corroded to ensure that the SBS anti-leakage membrane layer hot-melted on the inner end of the concrete drainage pipe has the proper anti-seepage effect in subsequent applications.

Description

technical field [0001] The invention belongs to the technical field of building material pipe structures, and more specifically relates to a high-durability concrete drainage pipe and its production process. Background technique [0002] In urban construction projects, concrete drainage pipes are indispensable, and currently commonly used drainage pipes are made of concrete. [0003] Based on the above, the inventors have found that the existing concrete drainage pipe has the following disadvantages: after the concrete is prepared, tiny voids are easily left inside, and when the drainage pipe is prepared with it, its durability is not good, and when it is subjected to a large force It is very easy to collapse; after the concrete drainage pipe is prepared, it is usually placed in the open place, and its open end is not blocked. Liquids such as water, animals and gravel will enter the inner end surface of the concrete drainage pipe, causing corrosion or wear damage, and, Some...

Problems solved by technology

[0004] In order to solve the above technical problems, the present invention provides a high-durability concrete drainage pipe and its production process to solve the problem that after the concrete is prepared, tiny voids are easily left inside, and when the drainage pipe is prepared with it, its durability is not good , it is easy to collapse when it bears a large force; after the concrete drainage pipe is prepared, it is usually placed in the open place, and its open end is not blocked, and liquids such as water, animals and gravel will enter the inner end surface of the concrete drainage pipe, causing corrosion Or wear and tear damage, and some concrete drainage pipes have SBS leak-proof coiled material layer on the inner end surface, which causes the SBS leak-proof coiled material layer to be worn, damaged or corroded; During the inspection of the concrete drainage pipe of the coiled material layer, when the SBS leak-proof coiled material layer is damaged with tiny cracks that cannot be observed by the naked eye, the inspectors cannot effectively detect the problem
