Manufacturing method of shield segment grouting pipe

The invention discloses a manufacturing method of a shield segment grouting pipe, and relates to the technical field of shield tunneling machines. Comprising the steps that firstly, a threaded steel pipe is blanked, and the threaded steel pipe is placed on a clamp; secondly, girth welding is conducted, specifically, girth welding is conducted on the threaded steel pipe, and a grouting pipe in a fixed shape is welded; step 3; the welded grouting pipe is taken down from the clamp; and fourthly, the welded grouting pipe is subjected to anti-corrosion treatment. According to the grouting pipe production line, efficient production and rapid production of grouting pipes can be achieved, the labor cost of the grouting pipes can be effectively reduced, and then the production efficiency of shield segments can be improved. 本发明公开了一种盾构管片注浆管的制造方法，涉及盾构机技术领域。包括：步骤一：螺纹钢管下料，将螺纹钢管放置在夹具上；步骤二：环缝焊接，对螺纹钢管进行环缝焊接，焊接成固定形状的注浆管；步骤三；将焊接好的注浆管自夹具上取下；步骤四：对焊接好的注浆管进行防腐处理。本发明可以实现对注浆管的高效生产和快速生产，能够有效降低注浆管的人工成本，进而能够提高盾构管片的生产效率。
