An assembly structure of an arch-type precast culvert for pipe installation and a culvert construction method using the same are provided to maintain stable structure of the precast culvert by enhancing vertical shear stress and bending resistance so as to prevent bulging of the culvert joint. A construction method of an arch-type precast culvert for pipe installation comprises the steps of: organizing a foundation to place an assembly structure of an arch-type precast culvert; locating a base plate(20), in which a support protrusion(22), a waterway part(24), a subsidence prevention expansion part(26) and a shear key groove are formed, on the foundation; inserting a shear key of an arch-type top plate(10) in the shear key groove of the base plate; setting a connecting socket(30) in the joint of the top plate as the bottom part of the connecting socket is inserted to a connecting socket binding groove(222); and filling grout in an internal filling space(32) of the connecting socket through a filler hole(34). |
