Attractive and practical composite material well cover

Abstract

The invention relates to an attractive and practical composite material well cover. The well cover has attractive appearance, is convenient to match a ground environment and consists of a base and a cover; both the base and the cover consist of lower surface layers, upper surface layers, middle frameworks, and upper and lower filling layers, wherein the lower surface layers are filled with glass fiber cloths; the upper surface layers are filled with an adhesive formed by mixing colored stone and resin; the middle frameworks are filled with glass fiber racks or glass fiber disks made by bonding glass fiber yarn and resin; the upper and lower filling layers are positioned between the upper and lower surface layers and the middle frameworks and are filled with an adhesive formed by mixing quartz sand and the resin. The upper surfaces are attractive and wearable and the colored stone can be selected as required, so the defects of single surface color, poor appearance and poor environment matching property of the well cover in the prior art are overcome and high practicability is achieved.

Description

technical field The invention relates to a construction engineering product, in particular to an aesthetically pleasing and practical composite material manhole cover with reliable quality and easy appearance matching with the use environment. Background technique In the construction of municipal engineering, a large number of manhole covers need to be used. For a long time, my country has always used cast iron manhole covers as the traditional mainstream product. In the past ten years, cement concrete manhole covers reinforced with steel bars, steel fibers, and glass fibers have also begun to occupy a certain market share. Their common advantage is high strength, and they are more durable in the ground environment without particularly strong external impact. Their common disadvantages are brittle texture, poor vibration resistance and pressure resistance. If they are installed on urban roads or building aisles with a lot of traffic, it is easy to cause the manhole cover to...
