A prefabricated assembly type grouted concrete inspection well comprises prefabricated blocks, and the prefabricated blocks are spliced end to end to form a closed loop and stacked in multiple layers to form the inspection well. Wherein each precast block comprises an inner ring layer, an outer ring layer and a connecting layer; the connecting layer is arranged between the inner ring layer and the outer ring layer; a pair of connecting layers is arranged, and a grouting area is formed between the connecting layers; the connecting layer comprises a connecting part and a limiting part; at the upper end of the connecting layer, the limiting part is convex outwards; and at the lower end of the connecting layer, the limiting part is in an inward concave shape, so that the limiting part located at the lower layer is inserted into the lower end of the limiting part located at the upper layer during vertical stacking, and limiting is completed through the connecting part. 一种预制装配式灌芯混凝土检查井，包括：预制块，预制块首尾拼接形成闭环，并堆叠多层形成检查井
