The utility model discloses a forepoling pipe shed structure under a silty-fine sand geological condition and a construction method of the forepoling pipe shed structure under the silty-fine sand geological condition. The forepoling pipe shed structure comprises a door-shaped pipe shed arranged along the outer contour line of a designed box culvert, and a plurality of horizontal jet grouting pilesare arranged around each steel pipe of the door-shaped pipe shed. And the adjacent horizontal jet grouting piles are mutually engaged and overlapped, and the horizontal jet grouting piles are mutually engaged and overlapped with the adjacent steel pipes to form a steel pipe and horizontal jet grouting pile consolidation body. The horizontal jet grouting pile has the advantages that slurry of thehorizontal jet grouting pile is limited in the soil body reinforcing range of the n-shaped pipe shed, and the slurry injection position and range can be controlled through the jet grouting pile machine; the high-pressure cemen
