Description

Technical Field

[0001] The utility model relates to the technical field of coal mining, in particular to a wind bridge construction support structure. Background Art

[0002] In the process of coal mining, wind bridges, as key nodes of the ventilation system, are often located at the intersection of tunnels and are easily affected by the deformation of the tunnel floor and the impact of slag, which can cause cracks in the wind bridge walls or even collapse, seriously threatening the stability of the ventilation system and mine safety. Traditional wind bridges are complex and time-consuming to repair, and after the wind bridge walls are removed, the bridge deck loses support, which can easily cause safety hazards such as slag outflow. Summary of the invention

[0003] The utility model aims to solve the problems raised in the background technology and provides a wind bridge construction support structure.

[0004] The technical solution of the utility model to achieve the above purpose is as follows:

[0005] A wind bridge construction support structure comprises a connecting rope, a lane, a steel mesh, an artificial wall, a bridge deck, a ceiling rope, a connecting channel steel and an I-beam; the two ends of the connecting rope are fixedly connected to the lane walls on both sides of the lane wind bridge, the connecting rope is fixedly connected to the steel mesh, the artificial wall is located in the lane and the upper end is fixedly connected to the bridge deck, the lower end of the artificial wall is fixedly connected to the bottom of the lane, the artificial wall is fixedly connected to the connecting rope, the artificial wall is fixedly connected to the steel mesh, the ceiling rope runs through the bridge deck and is fixedly connected to the connecting channel steel, and the I-beam is located between the bridge deck and the connecting channel steel and is fixedly connected to the connecting channel steel.

[0006] Preferably, a rope clip is provided on the connecting rope, and there are multiple connecting ropes respectively located on the sides of the laneway wind bridge, and the connecting ropes corresponding to the two laneways on each side of the laneway are fixedly connected by the rope clip.

[0007] Preferably, a reinforcement layer is provided on the bridge deck, the reinforcement layer is fixedly connected to the bridge deck, and the reinforcement layer is made of loess and cement.

[0008] Preferably, a clamping plate is provided on the I-beam, and the clamping plate is located between the I-beam and the bridge deck and is fixedly connected to the I-beam.

[0009] The utility model provides a wind bridge construction support structure, through its structural design, a slag retaining net is combined with a connecting rope and a steel mesh to form a buffer body, and slag or sand in a woven bag is used to build an artificial wall close to the slag retaining net in the slag retaining net formed by the connecting rope and the steel mesh. After the wind bridge is topped, the slag falls directly into the artificial wall, avoiding the cleaning of slag during the construction of the wind bridge wall. When the personnel build the wind bridge wall, they stand outside the slag retaining net to ensure safe operation. After the construction is completed, the wind bridge wall is blocked by the artificial wall so that it does not come into direct contact with the slag, avoiding deformation and damage due to the squeezing of the slag, thereby improving the integrity and stability of the wind bridge, extending the service life of the wind bridge, and improving the safety factor of the wind bridge construction. Two sets of ceiling ropes are constructed in the tunnel at a distance of 0.5m from the bridge deck, and the connecting channel steels are fixed to the ceiling ropes with locks. Then two I-beams are fixed to the connecting channel steels, and the locks are pulled and expanded to suspend the bridge deck, thereby improving the stability of the bridge deck. When the wind bridge wall needs to be repaired, since the bridge deck is supported by the I-beams, the wind bridge wall can be directly and quickly dismantled and rebuilt, greatly shortening the maintenance cycle. Compared with the prior art, the utility model improves the integrity and stability of the wind bridge, extends the service life of the wind bridge, and improves the safety factor of the wind bridge construction. At the same time, the wind bridge wall can be directly dismantled and rebuilt after the wind bridge wall is deformed, thereby avoiding the problem of the bridge deck being unable to support and slag gushing out after the traditional wind bridge wall is dismantled.
