The invention relates to slurry for pebble and boulder stratum construction. The slurry is characterized by comprising the following components: 50 to 70 Kg/m<3> of bentonite, 1.2 to 1.8 Kg/m <3> of carboxymethyl cellulose, 0.08 to 0.12 Kg/m<3> of a slurry auxiliary agent, 4.6 to 5 Kg/m<3> of sodium carbonate and the balance of water. The slurry is good in wall protection effect and little in slurry loss, groove wall collapse does not occur, and the construction requirement is met.
本发明涉及一种用于卵石及孤石地层施工的泥浆，其特征在于，所述泥浆中各组分及含量如下：膨润土50Kg/m～70Kg/m、羧甲基纤维素1.2Kg/m～1.8Kg/m，泥浆助剂0.08Kg/m0.12Kg/m，纯碱4.6Kg/m～5Kg/m，其余为水。该泥浆护壁效果较好，泥浆流失少，未出现槽壁坍塌，满足施工要求。
