提高水泥土搅拌墙在岩溶地质中入岩速率的研究

STUDY ON IMPROVING ROCK ENTRY RATE OF CEMENT-SOIL MIXING WALL IN KARST GEOLOGY

主要介绍水泥土搅拌墙在岩溶地质中入岩速率施工研究。经过对铣头、膨润土加入量进行反复论证优化,解决了水泥土搅拌墙在岩溶地质中入岩速率慢等问题。对水泥土搅拌墙在岩溶地质中施工进行固化做法及严密的管控验收制度,确保水泥土搅拌墙在岩溶地质中施工速率满足工期要求,同时保证水泥土搅拌墙成形质量符合要求,为同类工程提供借鉴经验。

This paper mainly introduces the research on rock entry rate construction of cement-soil mixing wall in karst geology.After repeated argumentation and optimization of milling head and bentonite addition amount,problems such as slow rock entry rate of soil-cement mixing wall in karst geology were solved.The solidification method and strict control and acceptance system for cement mixing wall construction in karst geology are carried out to ensure that the construction rate of cement mixing wall in karst geology meets the requirements of the construction period,and the forming quality of cement mixing wall meets the requirements,which provides reference experience for similar projects.
