The invention provides a main and assistant type continuous concrete wall. The length of main piles of the structure is larger than the length of assistant piles; according to the engineering practice condition, the ratio of the assistant piles to the main piles is 1/2 to 2/3, one assistant pile is arranged between two corresponding and adjacent main piles, the center distance of every two adjacent main piles is about 3 m to 6 m, reinforcing steel bars of the main piles and the assistant piles are tied together, and the main and assistant piles form the continuous concrete wall in the cast-in-place concrete process; and the main and assistant piles are connected through steel pull rods. Compared with a traditional continuous concrete wall, the length and the thickness of the assistant piles are greatly reduced; the length and the thickness of the main piles are slightly increased; and the final work amount can be reduced by 30% to 50%. 本发明提供种主辅桩式地连墙结构，该结构的主桩的长度大于辅桩的长度，依据工程实际情况，辅桩与主桩之比为1/2～2/3，在相邻两根主桩之间设置辅桩，相邻
