Slurry balance steel pipe jacking grouting hole wing ring structure and construction technology

The invention relates to a slurry balance steel pipe jacking grouting hole wing ring structure and a construction technology. A slurry balance steel pipe jacking grouting hole wing ring structure comprises a pipeline body, a grouting hole is formed in the pipeline body, one end of the pipeline body is used for installing a jacking machine head, the peripheral face of the pipeline body is sleeved with a wing ring, the wing ring is provided with a large-diameter section and a small-diameter section, the large-diameter section covers the periphery of the grouting hole, and the small-diameter section covers the periphery of the grouting hole. A channel allowing slurry to flow out is formed between the inner circumferential face of the large-diameter section and the outer circumferential face of the pipeline body, and the small-diameter section is located on the side, close to a pipe jacking machine head, of the large-diameter section. When the grouting hole wing ring structure of the slurry balance steel pipe jac
