一種重疊既有地下連續墻施工新的地下連續墻的成槽工藝制造技術

本發明專利技術公開了一種重疊既有地下連續墻施工新的地下連續墻的成槽工藝。其通過導墻外放，銑槽機刀架向外傾斜，沿導墻以恒定的小斜率向下銑鑿成槽。成槽過程中，通過銑槽機刀架的調整板調節刀架以一定斜率鑿銑成槽能夠避免銑槽機切削到既有連續墻，從而可靠的保護連續墻和銑槽機刀架，因而成槽過程更安全。同時，成槽過程中刀架傾斜鑿銑，其受到的切削阻力也更小，切削更加順暢，效率更高。

Process for forming a new underground continuous wall overlapped with an underground continuous wall

The invention discloses a groove forming technique for overlapping underground continuous walls to construct a new underground continuous wall. Through the outside of the guide wall, the slot milling machine tool knife is inclined outwards and is milled into a groove along the guiding wall with a constant small slope. Grooving process, with a certain slope cut milling groove can avoid milling machine cutting to both continuous wall by adjusting plate slot milling machine tool adjustment tool, so as to protect the reliable continuous wall and milling machine tool, so the grooving process more secure. At the same time, in the process of grooving, the tool holder is inclined, cutting and milling, and the cutting resistance is smaller, the cutting is more smooth and the efficiency is higher.
