A rubber connector for a manhole and a construction method thereof are provided to preclude waste water or underground water from being flown through a combined area between a connector and a manhole branch pipe by placing a water swelling waterproof rubber packing at the combined area of the manhole branch pipe. A rubber connector with a circular type is made of rubber having excellent water tightness. The connector includes a front part(10) and a rear part(20). At least one water swelling waterproof rubber packing(30) is mounted among projections, and the front part is integrated at the manhole wall when constructing the manhole. The rear part is placed at the other side of the front part and extended to the outside of the manhole wall with predetermined length. A manhole branch pipe(200) is inserted in the manhole wall. The inner diameters of the front part and the rear part are gradually larger toward the rear part. |
