Rigid Alloy Plastic Bridge Drain Pipe

Abstract

A rigid alloy plastic bridge drain pipe comprises an embedded pipe body and a lower adapter; the lower end of the embedded pipe body is connected with the upper end of the lower adapter; a limit stand is arranged on the inner wall of the lower end of the embedded pipe body; a downstream seepage-proof eave is arranged on the edge of the limit stand; the upper end of the lower adapter is connected to the inner wall of the embedded pipe body on the outer side of the downstream seepage-proof eave through threads; a pitted surface layer is arranged on the outer wall of the embedded pipe body; outward seepage-proof concave-convex grooves are formed in the pitted surface layer; the embedded pipe body is made of rigid alloy plastic, and the rigid alloy plastic is formed in a manner that PC, PBT, PET and ABS are synthesized and are subjected to extrusion granulation at 250-350 DEG C and then injection-compression moulding by an injection molding machine die. The rigid alloy plastic bridge drain pipe has the advantages of being strong in antioxidant properties, corrosion-resistant, higher in mechanical strength, non-aging, free from toxin decomposition, acid-resistant and alkali-resistant, heat-resistant and weather-resistant, good in dimensional stability and impact resistance performance and high temperature-resistant and cold-resistant, and is adapted to diverse climates and severe environments.

Description

technical field [0001] The invention relates to the technical field of bridge pipes, in particular to a rigid alloy plastic bridge drain pipe. 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] Bridge drain pipes can be divided into cast iron drain pipes and PVC drain pipes according to their materials. These two kinds of drainpipes all have the following disadvantages: [0004] Cast iron drainpipes are too rough, resulting in waste of energy, and some are severely corroded and polluted during use, especially rust stains are often left on the ...

AI Technical Summary

Problems solved by technology

[0004] Cast iron drainpipes are too rough, resulting in waste of energy, and some are severely corroded and polluted during use, especially rust stains are often left on the cement surface; moreover, cast iron drainpipes are difficult to process and manufacture, high in production costs, and difficult to install and other shortcomings

[0005] The oxidation resistance, corrosion resistance, and mechanical strength of PVC drain pipes are not high, and there are aging phenomena. The heat and weather resistance, dimensional stability, and impact resistance are extremely poor, and they cannot adapt to various outdoor climates and harsh environments for a long time.

[0006] PVC 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 from the bone, and water seeps out from the gaps, causing watermarks on the bridge floor, and poor water-proof and seepage-proof performance
