a protective tube 12 is sleeved on the secondary cable 10 positioned at the turning position, the protective tube 12 is a yellow cured tube, and the yellow cured tube protects the secondary cable 10 from being damaged by expansion and contraction stress at the turning position;
after the secondary cable 10 is laid, a filler strip 9 is embedded in the upper part of the secondary cable 10 and is filled with a caulking material, the filling height of the filler strip is flush with the pavement of the old pavement 11, and the caulking material is a silicone adhesive material.
When the secondary cable 10 is laid in the slab joint, the secondary cable 10 is laid one by one in a mode of multilayer superposition, and after the laying is completed, the filler strip 9 is embedded in the upper part to protect the secondary cable 10. The model number of the special secondary cable 10 for the navigational lamp 2 is DJ-JDKR-500V 1 multiplied by 2.5mm 2 Or 1X 4mm 2 。
After the secondary cable 10 is laid, it further includes:
wrapping the secondary cable 10 in the protection conduit 6 by cotton cloth, and sealing the pipe orifice of the protection conduit 6;
the pipe orifice of the pre-buried protection conduit 6 is reserved with a preset height for injecting silicone adhesive for plugging.
The secondary cable 10 in the protection conduit 6 is wrapped by cotton cloth, the opening of the protection conduit 6 is tightly plugged by tightening the cotton cloth, and the opening of the pre-buried protection conduit 6 is reserved to be about 25mm in height for plugging by injecting silicone adhesive materials.
In the embedded navigation aid lamp installation wiring method based on new and old pavement connection of the embodiment, the new seam 3 is cut on the old pavement 11, and the secondary cable 10 is laid by the new seam 3 and the original slab seam, so that the damage to the old pavement 11 is smaller compared with the existing grooving wiring construction method and the horizontal directional drilling jacking pipe construction method. Because grooving and groove cleaning and horizontal directional drilling are not needed, the grooving and groove cleaning time and the horizontal directional drilling pipe jacking time are saved, the construction speed is greatly improved, the potential safety hazard is reduced, and the construction can be performed under the construction condition without stopping navigation. Because no groove is formed, the groove does not need to be backfilled, and compared with the method of backfilling the groove by using concrete, the method improves the safety of airport operation and reduces the later maintenance cost.
The protection conduit 6 is pre-buried in the new road surface, and the pipe orifice of the protection conduit 6 is perfectly matched with the slab joint of the old road surface 11, so that the later maintenance is convenient, and the secondary cable 10 can be prevented from being damaged by sharp edges and corners of the protection conduit 6 during the cutting operation of the panel transverse joint of the new road surface. The secondary cable 10 is laid in the slab joint for protection, so that the service life of the secondary cable 10 is prolonged, and the secondary cable 10 is convenient for later maintenance and the like. The gap between the embedded navigation aid lamp base and the lamp pit 1 is filled with the road surface glue, so that the filling density is greatly improved due to the strong fluidity of weber glue, and the drying time is short, thereby being particularly suitable for the construction requirement of an airport without stopping navigation.
It should be noted that: the cutting of the new seam 3 on the old road surface 11 and the pre-burying of the protection conduit 6 on the new road surface can be performed simultaneously or separately, and the specific sequence is not limited.
The weber glue of this embodiment is Wei Bajiao, which is an existing product.
The above examples illustrate only a few embodiments of the invention, which are described in detail and are not to be construed as limiting the scope of the invention. It should be noted that it will be apparent to those skilled in the art that several variations and modifications can be made without departing from the spirit of the invention, which are all within the scope of the invention.
