Description

Multifunctional Polymer Trench {Multifunctional Polymer Trench}

The present invention relates to a multifunctional polymer trench, and more particularly, by manufacturing a trench cover with a polymer composite to impart elasticity to the trench cover, and inserting a reinforcing material therein to support a heavy object from the bottom thereof, thereby securing durability and reducing damage caused by impact. A trench including a multifunctional trench cover that reduces noise and does not cause corrosion.

In general, gratings are installed in drainage pipes where a lot of sewage, sewage, and rainwater collect on roadsides, residential areas, sidewalks, parks, buildings, factories, ships, etc. It is installed and used so that sewage and rainwater can be treated smoothly.

Grating types are largely divided into civil engineering, plant, and construction purposes depending on their use. Here, there are two types of grating: one for collecting rainwater and the other for drainage. It is classified as one for crossing and one for side gutter installed on the side of the road.

At this time, trench-related products are generally manufactured and used with metal, but price competitiveness weakened due to the rise in metal material price and the appearance of low-priced foreign products, and contamination of the surroundings due to metal corrosion occurred. Poor working environment such as mold making, melting work, and casting processing work, complicated processes, air pollution by waste gas, waste casting sand containing heavy metals, and frequent use of existing steel products (tree protection pipes, manhole covers, farm waterway covers, etc.) Theft and the resulting increase in the risk of safety accidents, occurrence of civil complaints, and even social problems (theft is at a serious level in foreign countries) are a reality.

In particular, when the metal grating is used for a long period of time or a heavy vehicle passes by, the grating bounces up and falls, causing noise such as rattling (≤ 100dB) as the grating hits the side of the support frame, and it is firmly connected to the adjacent grating. Since it was not fixed, phenomena such as separation or bending occurred due to complex loads.

Accordingly, Korean Patent Registration No. 10-1564013 'Noise Trench Cover' simplifies installation by assembling a trench cover by fitting it, and discloses a technology for reducing noise caused by collision, but the body part is still made of metal. In terms of cost reduction, there were areas to be improved.
