What Is The Construction Process Of Bailey Bridge?

The construction process of Bailey Bridge: 1. To assemble first, the nose frame must be installed, and the nose frame installation of Bailey bridge: first assemble the truss of Bailey Bridge on the rock that pushes out the shore. One end of the truss piece is placed on the rock, and the other end is on temporary skids. 2. The yin and yang heads of the truss pieces are the same, place the first beam behind the front vertical rod, and place the two rows of holes in the bottom surface of the beam

The construction process of Bailey Bridge:

1. Assemble first to install the nose piece, Bailey bridge nose piece installation: first assemble the truss of the Bailey bridge on the rock that pushes out the shore. One end of the truss piece is placed on the rock, and the other end is placed on the temporary skid.

2. The male and female heads of the truss pieces are the same, place the first beam behind the vertical rod at the front end, and insert the two rows of holes in the bottom surface of the beam into the bolts on the backing plate of the lower chord beam of the two truss pieces, and clamp them with the beam clamp. Do not tighten it for now, and then tighten it after the diagonal brace on the beam is installed.

3. Install the second section of the truss piece. At the same time, the Bailey bridge should install diagonal braces on the truss beam of the previous section, and install the beam behind the vertical rod at the front end of the second section of the truss, and clamp it lightly with the beam clamp. Tighten, and then tighten after the diagonal brace on the beam is installed.

4. Install the third section of truss, install wind-resistant tie rods on the first section of truss sheets, and install diagonal braces on the beams of the second section of truss sheets. The nose piece installation is carried out in sequence, and a total of four truss pieces need to be installed as the nose piece.

5. Bailey Bridge has introduced hoist traction. During the traction process, unified command, consistent steps, and coordinated operation are required. Check the operation of the rollers and the bridge at any time. If there is a problem, stop the operation immediately and continue after the problem is solved. advance.

6. After the bridge is pushed into position, remove the nose frame, use a jack to stand against the lower chord of the bridge, check the beret and tighten all the supports, beam fixtures and wind-resistant tie rods.

7. Finally, lay the longitudinal beams, bridge decks, steel plates, etc. of the Bailey Bridge.

Bailey Bridge, invented by British engineer Donald West Bailey in 1938. This bridge is made of high-strength steel to a lightweight standard
