喷纳米混凝土配合比试验

Mix Proportion Test of Sprayed Nano Concrete

TB水电站地下洞室因渗水及断层破碎带影响,岩石表面湿润,普通C25混凝土施喷效果不佳。为确保洞室安全稳定,采用C25纳米喷射混凝土进行配合比试验。该方案借鉴了类似工程的成功经验,旨在解决基岩面渗水导致的混凝土施喷问题。纳米喷射混凝土作为重要的支护手段,对于提高洞室安全施工具有关键作用。通过试验优化配合比,将有效提升混凝土的施喷效果,确保洞室稳定与安全。

The underground cavern of TB hydropower station is affected by water seepage and fault fracture zones,resulting in a moist rock surface.Therefore,the spraying effect of ordinary C25 concrete is not good.To ensure the safety and stability of the cavern,C25 nano sprayed concrete is used for mix ratio testing.This plan draws on the successful experience of similar projects and aims to solve the problem of concrete spraying caused by water seepage on the bedrock surface.Nanojet concrete,as an important support method,plays a crucial role in improving the safety of tunnel construction.By optimizing the mix proportion through experiments,the spraying effect of concrete will be effectively improved,ensuring the stability and safety of the tunnel.
