The utility model provides a spliced concrete precast block for rail transit, and relates to the technical field of road shoulder laying. The concrete precast block comprises a foam concrete block and reinforcing ribs, the foam concrete blocks are rectangular; the reinforcing ribs are prefabricated in the foam concrete block, the number of the reinforcing ribs is multiple, and the reinforcing ribs are evenly arranged on the foam concrete block. On one hand, the problems that a concrete precast block is large in dead weight and low in carrying and mounting efficiency are solved; and on the other hand, the problems that the elastic modulus of a concrete precast block is poor, and vibration and impact cannot be absorbed and dispersed when a train passes through a rail are solved. 本实用新型提出了用于轨道交通的拼接式混凝土预制块，涉及路肩铺设技术领域。该混凝土预制块包括泡沫混凝土块和加强筋；上述泡沫混凝土块呈矩形；上述加强筋预制于上述泡沫混凝土块内，上述加强筋的数量为多个，且多个加强筋均匀布置于上述泡沫混凝土块。本实用新型一方面解决了混凝土预制块自重大，搬运与安装效率低；另一方面解决了混凝土预制块弹性模量较差，无法起到列车通过轨道时传递而来震动与冲击的吸收与分散作用的问题。
