The invention discloses a support structure for bilge well construction. The support structure is characterized in that the slope height ranges from 1.5 m to 2 m, the slope gradient ranges from 35 degrees to 40 degrees, an anchor rod is inserted into the slope portion, the angle of the anchor rod ranges from 30 degrees to 35 degrees, glass bead heat preservation mortar is sprayed to the surface of a slope, and the thickness of the glass bead heat preservation mortar ranges from 20 mm to 30 mm; the distance between cryovials in a first row and a bilge well ranges from 0.7 m to 0.9 m, the space between every two adjacent cryovials in the first row ranges from 0.7 m to 0.8 m, and the depth of frozen tubes in a first row is larger than the construction depth of the bilge well by 1-1.5 m; the space between every two adjacent cryovials in a second row ranges from 0.9 m to 1.0 m, and the depth of frozen tubes in a second row is larger than the construction depth of the bilge well by 1-1.5 m. The cryovials in the first row and the cryovials in the second row are arranged in a quincunx staggered mode. Temperature measuring tubes located between the cryovials in the first row and the cryovials in the second row and are arranged every 15-20 meters, and the depth of the temperature measuring tubes is half that of the cryovials. Extrusion-preventing holes are formed in the positions 6-8 meters away from the cryovials in the second row, the diameter of the extrusion-preventing holes ranges from 300 mm to 350 mm, the depth of the extrusion-preventing holes ranges from 12 m to 15 m, and the space of the extrusion-preventing holes ranges from 5 m to 7 m. The construction speed is high, and the safety performance is good.
