This utility model relates to a glass fiber pipe joint and a seabed laying pipe. The glass fiber pipe joint includes a connecting sleeve, two joint fixing rings and a rigid connecting structure; the connecting sleeve is used to set the ports of two adjacent glass fiber pipes in the opposite end of the connecting sleeve; two joint fixing rings are respectively fixed on the outer side walls of the ports of two adjacent glass fiber pipes; the rigid connecting structure includes a connecting joint plate, which is used to rigidly connect the two joint fixing rings. The glass fiber pipe joint provided by the utility model achieves the tight connection of the joint fixing rings fixed at the ports of the adjacent glass fiber pipes on the opposite ends through the joint connecting plate, so that the glass fiber pipe joint forms a rigid connection.
