[0002] The construction of deep foundation pits for linear pipeline corridors is usually a linear engineering flow construction. The excavation progress of deep foundation pits for linear pipeline corridors is easily affected by rainy days. Even if drainage measures such as intercepting ditches and sump wells are set up, the water accumulation situation in deep foundation pits on rainy days is not optimistic. It takes a lot of time to pump out the water from the foundation pits, and the construction progress of the pipeline corridor is greatly constrained.

[0003] In summer, construction work faces the problems of high daytime temperatures and deep foundation pits facing direct sunlight.

Water will accumulate in the deep foundation pit on rainy days, and construction cannot be carried out during high temperature periods in hot weather.

[0069] Based on this, an embodiment of the present invention provides a multifunctional integrated skylight used in the construction of a deep foundation pit of a linear pipeline corridor, which is described below through specific embodiments.

[0070] The embodiment of the present invention provides a self-moving multifunctional integrated canopy for use in the construction of a linear pipe gallery deep foundation pit, referring to Figure 1-Figure 6 As shown, it includes a canopy body 1, a plurality of pulley 22 structures 2 and a track structure 3;

[0073] The track structure 3 includes a guide rail 31 and a track body 32 arranged up and down, and can be arranged on both sides of the deep foundation pit of the linear pipe gallery; the track body 32 has an I-shaped cross section and includes an upper steel plate 321, a support steel plate 323 and a lower steel plate 322 connected in sequence from top to bottom;

[0074] The pulley 22 structure 2 includes a support frame 21, a pulley 22 and a stopper 23;

[0075] The support frame 21 includes a top plate 211 and two side plates 212. A support shaft 24 is disposed between the two side plates 212. The pulley 22 is sleeved on the support shaft 24 and can slide on the guide rail 31.

[0076] The two side plates 212 are respectively fixed with the limiting members 23, which are arranged below the support shaft 24 and can extend between the upper steel plate 321 and the lower steel plate 322;

[0077] The top plate 211 is fixed below the corresponding column 12 so that the pulley 22 can drive the canopy body 1 to slide on the guide rail 31 .

[0078] In the embodiment of the present invention, the scissor frame 13 is movably arranged between two adjacent columns 12 in the same row, so that the distance between the columns 12 can be adjusted by the extension and retraction of the scissor frame 13, thereby realizing the overall extension and retraction of the canopy body 1. During the transportation and storage of the canopy body 1, the canopy body 1 can be retracted to the most compact state to save space.

[0079] In the embodiment of the present invention, the specific method of movably setting the scissor frame 13 between the columns 12 may include: hinge one end of the upper and lower ends of the scissor frame 13 with the column 12, and slide the other end with the column 12. Figure 6 As shown, a fastener 14 can be fixed on the side wall of the column 12, and a lifting ring 15 can be set on the column 12, and one end of the upper and lower ends of the scissor frame 13 is passed through the fasteners 14 on the two adjacent columns 12, and the other end is fixed to the lifting ring 15 of the two adjacent columns 12, so that the distance between the adjacent columns 12 can be adjusted by the extension and contraction of the scissor frame 13. Optionally, the lifting ring 15 is a customized lifting ring 15 with screws welded on the outside, and the end of the scissor frame 13 passes through the screws of the lifting ring 15 to achieve a fixed connection between the lifting ring 15 and the scissor frame 13.

[0080] In a specific embodiment, the column 12 can be made of a round steel tube, the scissor frame 13 can be made of a square steel tube, and the inner diameter of the ring 15 is greater than the outer diameter of the column 12. For example, the column 12 can be made of a round steel tube with a specification of φ76×1.8mm, the inner diameter of the ring 15 can be set to 83mm, and the scissor frame 13 can be made of a square steel tube with a specification of 40×20×1.5mm.

[0081] In the embodiment of the present invention, refer to Figure 5 As shown, the limiting member 23 includes a limiting short shaft 231 and a rolling ring 232 sleeved on the limiting short shaft 231. The limiting short shaft 231 is fixed to the inner side of the side plate 212 and is located below the pulley 22. The rolling ring 232 can contact the bottom surface of the upper steel plate 321 and can roll along the bottom surface of the upper steel plate 321. The top plate 211 is fixed to the bottom of the column 12. When the canopy body 1 slides along the track structure 3, the pulley 22 rolls and slides on the guide rail 31. The limiting member 23 extends between the upper steel plate 321 and the lower steel plate 322. The rolling ring 232 rolls and slides relative to the bottom surface of the upper steel plate 321, so that the pulley 22 structure 2 and the track structure 3 are more evenly stressed during the sliding process of the canopy body 1, so that the canopy body 1 slides stably, and under the action of the limiting member 23, the pulley 22 is prevented from derailing or the canopy body 1 is tilted or overturned to the side. The fixing connection method between the top plate 211 and the column 12 includes but is not limited to welding.
