A large section U-shaped shield cutting receiving construction method comprises the following steps: step 1: V-shaped retaining wall support edge front slops are constructed on the two sides of a caveopening ring; step 2: the time for starting removing a cave gate is determined according to the shield excavation condition and the receiving process requirement, and the cave door is prepared to beremoved; step 3: the cave door is removed, firstly a steel scaffold is erected in the range of a cave door steel ring on a receiving base, rooting is performed in the receiving base, and receiving retaining walls on two sides are erected into a whole; the lower part of the scaffold is padded, the two sides of the scaffold are connected and fastened with the retaining walls respectively, and boardsare laid on cross arms and fixed with the cross arms; according to the cutting receiving technology, the strengthening and support measures of common cave opening rotary spraying, piles and the likein metro construction are replaced with the V-shaped retaining wall support edge front slops, and at the same time, the lifting requirement and the connection measure of cave opening edge front slopswith an open cut tunnel are considered. The problems of the cutting edge front slop stability and the open cut channel structure connection are solved.
