Wall protection slurry for underground diaphragm wall in pebble stratum and preparation method of wall protection slurry
The invention relates to the technical field of underground engineering construction, and particularly discloses pebble stratum underground diaphragm wall protecting slurry and a preparation method thereof. The pebble stratum underground diaphragm wall protecting slurry provided by the invention is prepared from the following components in parts by weight: 30 to 50 parts of bentonite, 20 to 30 parts of cement, 5 to 10 parts of shell powder, 3 to 8 parts of carboxymethyl cellulose, 1 to 3 parts of KH792 modified polypropylene fiber and 450 to 500 parts of water, further, the shell powder comprises shell powder with the particle size of 100-200 [mu] m and shell powder with the particle size of 800-1000 [mu] m; the invention further provides a preparation method of the pebble stratum underground diaphragm wall protecting slurry. The pebble stratum underground diaphragm wall protecting slurry provided by the invention is low in cost and good in protecting effect, a formed groove wall is excellent in stability, and the pebble stratum underground diaphragm wall protecting slurry can be prevented from collapsing for 120 hours and can meet the construction requirements of an underground diaphragm wall.
本申请涉及地下工程施工技术领域，具体公开了一种卵石地层地下连续墙护壁泥浆及其制备方法。本申请提供的卵石地层地下连续墙护壁泥浆，包括以下重量份的组分：膨润土30‑50份、水泥20‑30份、贝壳粉5‑10份、羧甲基纤维素3‑8份、KH792改性聚丙烯纤维1‑3份和水450‑500份；进一步地，所述贝壳粉包括粒径为100‑200μm的贝壳粉和粒径为800‑1000μm的贝壳粉；本申请还提供了上述卵石地层地下连续墙护壁泥浆的制备方法。本申请提供的卵石地层地下连续墙护壁泥浆的成本低、护壁效果好、形成的槽壁稳定性佳，并且可以保持120h不坍塌，能够满足地下连续墙的施工要求。
