High-strength energy-saving environment-friendly burglarproof water drain pipe for bridge

Abstract

The invention discloses a high-strength energy-saving environment-friendly burglarproof water drain pipe for a bridge. The water drain pipe comprises a water drain pipe, and a filter screen and a water collection hole fixed ring which are molded once, wherein the filter screen consists of a filter plate and splicing teeth arranged at the edge of the filter plate; the water drain pipe consists of a large-diameter straight pipe and a small-diameter straight pipe which are connected through a conical pipe; lugs are uniformly arranged on the inner wall of the large-diameter straight pipe; the water collection hole fixed ring is adhered with the lugs in the large-diameter straight pipe; splicing holes are formed by gaps between the water collection hole fixed ring and the lugs; the splicing teeth on the filter screen are arranged in the splicing holes and are respectively adhered with the water collection hole fixed ring and the large-diameter straight pipe; a pitted surface layer is arranged on the outer surface of the water drain pipe; a pitted surface layer on the small-diameter straight pipe is provided with spiral concave-and-convex grooves. The high-strength energy-saving environment-friendly burglarproof water drain pipe has the advantages of high in anti-corrosion property, acid-alkali resistant, anti-aging, free of rusting energy-saving, environment-friendly, and the like; the load of bridge is reduced, the engineering quality is improved, the service life of the pipe is greatly improved, the maintenance cost is reduced, and the burglar prevention problem is radically solved.

Description

technical field [0001] The invention relates to the technical field of pipelines, in particular to a high-strength energy-saving and environment-friendly anti-theft drain pipe for bridges. Background technique [0002] With the development of society, more and more pipes are used in real life. However, in the actual use of pipes, pipes of different lengths will be connected to each other to form a pipe channel. Among them, bridge drain pipes are used in railway and highway bridges, guardrails and other engineering fields to undertake the task of rainwater drainage and play an important role in maintaining the quality of bridge decks and ensuring safe passage. [0003] The drainage pipes on traditional railway and highway bridges are made of ordinary cast iron, without anti-theft measures, and the pipe body and pipe cover are almost connected by threads, resulting in serious loss of pipe cover and filter screen; the current railway and highway bridges More than 90% of the d...

AI Technical Summary

Problems solved by technology

[0003] The drainage pipes on traditional railway and highway bridges are made of ordinary cast iron, without anti-theft measures, and the pipe body and pipe cover are almost connected by threads, resulting in serious loss of pipe cover and filter screen; the current railway and highway bridges Over 90% of the drainpipes have been lost

[0004] In addition, the traditional drainage pipes are made of cast iron, and the drainage pipes are too rough, resulting in waste of energy; the pipe covers and filter screens are not strong enough, some are damaged during transportation, and some are severely corroded and polluted during use, especially on cement pavement Rust stains are often left; and cast iron drain pipes have disadvantages such as difficult manufacturing, high production costs, and difficult installation, which need further improvement

[0005] At the same time, plastic drainpipes or cast iron drainpipes with surface treatment have a smooth surface, and the adhesion strength with cement and other building materials is too small, which is easy to form gaps and cement seeps out of the gaps, causing watermarks on the bridge floor
