The invention discloses a construction method of a trench type cutting cement soil continuous wall and aims at solving the problems that in the prior art, when a chain cutter cuts a dense gravel layer or a soil layer with the uniaxial compressive strength larger than 5 Mpa, the construction speed is extremely low, and the cutter is seriously abraded. The construction method sequentially comprises the following steps that firstly, the depth of an underground soil layer with the uniaxial compressive strength of P1 in a foundation soil layer is explored; secondly, the trench type cutting is carried out on the foundation soil layer through rotation and transverse movement of the chain cutter, and a trench type cutting groove is cut in the foundation soil layer; thirdly, drilling work is carried out on the bottom of the trench type cutting groove through a drilling device, and the bottom of the trench type cutting groove is downwards machined to form an auxiliary cutting cut-in hole with the set depth; fourthly, the chain cutter stretches into the auxiliary cutting cut-in hole; and fifthly, the chain cutter carries out transverse cutting in the direction of the trench type cutting groove.
