Method for preparing light high-strength composite trench cover

Abstract

The invention relates to a method for preparing a light high-strength composite trench cover. The conventional concrete trench cover has heavy volume, is easily broken, and brings inconvenience for transportation, mounting and maintenance for constructors. The invention aims to develop the light high-strength composite trench cover with high strength, light weight, normalization and standardization, which uses high-strength low-alkali cement as a raw material, and is matched with porcelain granules, a reinforcing agent, slag and flyash packing materials, polyester granules and other materials, wherein the surface layer and the bottom layer of the light high-strength composite trench cover are cement mortar layers; two steel wire mesh inner layers are arranged in the cement mortar surface layer and the cement mortar bottom layer; the cement mortar granules, the reinforcing agent, the polyester granules, the slag and flyash packing materials and other light composite materials are filled in the steel wire mesh inner layers; and a cold-rolled ribbed reinforcing steel bar layer is clamped between the two steel wire mesh inner layers. The light high-strength composite trench cover is light, has high strength, nice appearance and smoothness, and is convenient to construct, mount and maintain.

Description

Technical field: [0001] The invention belongs to the technical field of building materials, in particular to a preparation method of a light-weight and high-strength composite trench cover. Background technique: [0002] At present, the concrete ditch cover used in the market is bulky and easily damaged, and its transportation, installation and maintenance are very inconvenient. Due to its bulkiness, the construction personnel are careless and easy to damage personnel, which brings inconvenience to the construction and costs money at the same time. It is time-consuming and labor-intensive, which not only wastes a lot of manpower and material resources, but also does not meet the national requirements for high efficiency, energy saving and environmental protection. Invention content: [0003] The object of the present invention is to provide a light-weight and high-strength composite trench cover preparation method according to the above-mentioned shortcomings, which effect...

AI Technical Summary

Problems solved by technology

[0003] The object of the present invention is to provide a preparation method of light weight and high strength composite ditch cover according to the above-mentioned deficiencies, which effectively solves a series of problems such as bulkiness, easy damage, and high labor intensity of construction that are difficult to overcome with traditional concrete ditch cover slabs. The defects of the factory have realized the standardized, batched and standardized integrated production of the factory, thereby improving the quality and output of the product, reducing labor intensity, and saving a lot of manpower, material and financial resources
