Water-dispersion-resistant grouting material for reinforcing water-rich stratum of subway tunnel and preparation method of water-dispersion-resistant grouting material
The invention discloses an anti-water-dispersion grouting material for reinforcing a water-rich stratum of a subway tunnel and a preparation method thereof. The grouting material comprises the following components in parts by mass: 250-280 parts of water, 290-320 parts of cement, 390-420 parts of medium-fine sand, 3-7 parts of hydroxyethyl cellulose ether and 20-50 parts of aluminum sulfate. The grouting material is good in fluidity, low in bleeding rate, excellent in water dispersion resistance and high in stability; the grouting agent is used for grouting a water-rich stratum of a subway tunnel, and can be quickly and fully injected and squeezed into cracks or gaps of the stratum; the concrete can be prevented from being dispersed by underground water in a water-rich stratum and can be quickly condensed to form a consolidated body; and the reinforcing effect on the water-rich stratum of the subway tunnel is good.
本发明公开了一种抗水分散的地铁隧道富水地层加固用注浆料及制备方法，其注浆料组分和质量配比是：水250～280份，水泥290～320份，中细砂390～420份，羟乙基纤维素醚3～7份，硫酸铝20～50份。该注浆料流动性好、泌水率低、抗水分散性能优良、稳定性高；用于地铁隧道富水地层注浆，既能快速充分的注入、挤进地层的裂隙或间隙中；又能避免被富水地层中的地下水冲散，并快速凝结形成固结体；对地铁隧道富水地层的加固效果好。
