Cement blanket of multi-layer structure

Abstract

The utility model discloses a cement blanket of multilayer structure relates to cement blanket technical field, including cement blanket, the surface of cement blanket is covered with water locking layer, water locking layer is used for when high gradient construction watering to carry out water locking operation, water locking layer includes rectangular frame, arc convex strip, and arc convex strip is used for intercepting water when watering, is used for avoiding the water flow on the ramp top rapid loss. The utility model discloses through setting water locking layer, through arc convex strip and straight line reinforcing strip, rectangular frame is composed of a plurality of grid and can store a certain amount of water, these water can be slowly absorbed by cement blanket, and then reach the effect of promoting even water slide, effectively avoid the moisture of the top of ramp of high gradient to cause the cement blanket hydration uneven, thereby causing the problem of insufficient strength, surface pulverization, effectively improve the paving quality of cement blanket on high gradient ramp.
