PROBLEM TO BE SOLVED: To obtain an existing pipe repair method which enables an easy installation of a tubular lining material having a desired thickness to an existing pipe with a simple operation, and further, can aim also a facilitation of a formation of layers having different properties to aim an accuracy of a curing operation. SOLUTION: The existing pipe repair construction method comprises a step that the tubular lining material in which a lining core material formed in a tubular form is in advance impregnated with an uncured resin is cured in a state introduced into the inside of the existing pipe which is a repair target, to carry out the repair of the existing pipe. In the method, the introduction of the tubular lining material is characterized in that a plurality of tubular lining materials 12, 14 are inserted respectively individually into the existing pipe 10, the tubular lining material 12 first inserted is most laterally-located, and subsequently an insertion is carried out inside in turn. According to the constitution, even in case of forming a thick tubular lining material, the tubular lining material of each simple is sufficient in the thickness not satisfying the thickness of the tubular lining material of a completed product, and the inserting work also turns easy.
