Road well lid produced by utilizing waste residue and production method thereof

Abstract

The invention relates to a road well lid produced by utilizing waste residue and a production method thereof. The road well lid is characterized by being prepared from the following raw materials in percentage by weight: 50%-60% of waste residue, 20%-30% of quartz sand and 20%-30% of 500# cement. Production steps are as follows: (1), stirring raw materials and 0.12% of water into a material mixture; (2), digesting the material mixture; (3), carrying out compression molding to obtain a well lid blank; (4), carrying out autoclaved curing at a high temperature of 200 DEG C under high pressure of 1.3 MPa; (5), detecting outline and quality, grading and piling up; (6), recycling after clearing. According to the invention, beneficial effects are as follows: the road well lid is produced by utilizing the waste residue, and the road well lid is prevented from being stolen as no recycling utilization value exists; compressive strength and rupture strength are good; the road well lid is durable in use, and the preparation is simple and practical.

Description

[0001] technical field [0002] The invention relates to a road manhole cover made of waste residue and a preparation method thereof. [0003] Background technique [0004] At present, the existing road manhole covers are generally made of cast iron. Because the materials have recycling value, they are often stolen and lost seriously, resulting in accidents of vehicle crashes and deaths. In order to solve the theft of the cast iron manhole cover, two methods are mainly adopted at present: the one is to install an anti-theft device on the cast iron manhole cover, but the cost is increased, but the problem cannot be fundamentally solved, and it brings inconvenience to the use, such as Chinese patent 93237579, 95241036, 96232738, 99227151 or the like; the 2nd, consider its no recycling value on the material, and such as Chinese patent 97202338, 97207516, 99231650.2 or the like.

Problems solved by technology

[0004] At present, the existing road manhole covers are generally made of cast iron. Due to the recycling value of the material, they are often stolen and lost seriously, resulting in accidents of car crashes and deaths.

In order to solve the theft of the cast iron manhole cover, two methods are mainly adopted at present: the one is to install an anti-theft device on the cast iron manhole cover, but the cost is increased, but the problem cannot be fundamentally solved, and it brings inconvenience to the use, such as Chinese patent 93237579, 95241036, 96232738, 99227151, etc.; the second is to consider its no recycling value in terms of materials, such as Chinese patents 97202338, 97207516, 99231650.2, etc.

But they have the following problems: (1) The periphery of the road manhole cover made of reinforced concrete or glass fiber reinforced plastic is easy to break, or even collapse as a whole.

(2) Road manhole covers made of plastic materials have very poor wear resistance, aging resistance and chemical corrosion resistance, and their bearing capacity decays quickly, which cannot meet the requirements of heavy traffic on urban roads
