Description

Technical Field

[0001] The invention belongs to the technical field of highway construction, in particular to a construction process and a construction device of an assembled corrugated steel box arch structure. Background Art

[0002] After the cross-section of the corrugated steel plate changes from straight to wavy, the cross-sectional inertia moment increases significantly. The corrugated steel plate is processed and assembled into a box-arch structure. The corrugated steel box-arch structure is a typical flexible structure that withstands larger live loads and higher cover soil through the interaction between the corrugated steel structure and the surrounding soil (the principle of common force between soil and soil).

[0003] A Chinese patent with publication number CN105926674A discloses a high-strength urban underground integrated pipe gallery, including a top plate, a bottom plate and two side plates composed of corrugated plates with protrusions on the outer side and / or the inner side, which are assembled to form a box-shaped pipe segment, and the box-shaped pipe segment is assembled along the axial direction to form an integrated pipe gallery; wherein, longitudinal beams are provided at the edges of the box-shaped pipe segment, and cross beams are provided at both ends of the top plate and / or the bottom plate along the axial direction of the box-shaped pipe segment, and columns are provided at both ends of the side plates, and the cross beams and columns are connected end to end to form a frame-type skeleton; wherein, the top plate is arched, and the direction of the arched texture is consistent with the extension direction of the pipe gallery. The structure composed of the top plate and the beams at both ends utilizes the principle of joint force between pipe and soil and continuous arch bridge. The plate and backfill soil are subjected to force synergistically. The direction of the arched texture is consistent with the extension direction of the corridor. In addition, beams are arranged side by side between adjacent top plates along the extension direction of the corridor. Except for the beams at both ends of the corridor, the horizontal components of the top plate on the beams are offset on the left and right, and the overall structure has a stronger bearing capacity.

[0004] When the corrugated steel box arch structure is assembled on site, the bottom plate of the corrugated steel box arch structure is adjusted to a horizontal level through multiple pipe sleepers. However, due to the complex construction site environment and the uneven ground, the heights of the pipe sleepers are different, and the staff are required to cooperate with the crane to ensure the level of the corrugated steel box arch structure by stacking the number of pipe sleepers, which increases the workload and difficulty of the staff.

[0005] To this end, the present invention provides a construction process and a construction device for an assembled corrugated steel box arch structure. Summary of the invention

[0051] like Figure 3 and Figure 5As shown, a mounting groove 15 is provided in the middle of the top surface of the base 1, and the inner wall of the mounting groove 15 is slidably matched with the outer wall of the hydraulic cylinder 2. A plurality of No. 1 springs 16 are fixedly connected between the bottom outer ring of the hydraulic cylinder 2 and the bottom outer ring of the mounting groove 15. A plurality of guide rods 17 are fixedly connected to the outer ring of the mounting groove 15. The guide rods 17 slide through the bottom outer ring of the hydraulic cylinder 2, and the outer ring of the guide rods 17 is sleeved on the inner ring of the No. 1 spring 16. A receiving groove 18 is provided on the bottom surface of the base 1, and a pressure plate 19 is slidably installed on the middle bottom surface of the mounting groove 15. A plurality of pressure rods 20 are fixedly connected to the bottom surface of the pressure plate 19. The pressure rods 20 slide through the top wall of the receiving groove 18, and the inside of the receiving groove 18 is slidably installed. There is a fixed plate 21, and a plurality of spikes 22 are fixedly connected to the bottom surface of the fixed plate 21. The top surface of the fixed plate 21 is fixedly connected to the bottom end of the pressure rod 20. A plurality of No. 2 springs 23 are installed between the bottom surface of the pressure plate 19 and the middle bottom surface of the mounting groove 15.

[0055] During work: at the construction site where the corrugated steel box arch structure needs to be installed, a foundation pit is excavated, and the anti-floating reinforcement is first buried and the cushion layer is poured according to the construction drawing; construction devices are placed on both sides of the bottom surface of the foundation pit, so that the pipe pillows 3 on both sides are opposite to each other, and the distance between the pipe pillows 3 on both sides matches the bottom plate size of the corrugated steel box arch structure, and the bottom plate is hoisted and placed on the pipe pillows 3;

[0056] The rubber strip 10 squeezes the bottom plate of the corrugated steel box arch structure, so that the rubber strip 10 is compressed.

[0058] After the bottom plate is adjusted to the level, the side plates of the corrugated steel box arch structure are hoisted and fixed with bolts. Adjustable rigid supports are set between the side plates and the bottom plate flanges. Then the top plate of the corrugated steel box arch structure is hoisted. The top plate and the side plates are fastened with bolts to complete the assembly of standard segments. The bottom plate and anti-floating reinforcement are welded on site. Finally, the outer side of the bottom plate is supported by formwork and poured with flowing self-compacting cement soil.
