Optionally, the drain hole is arranged from the water intercepting groove to the outside of the reducing groove box body in an inclined mode.
The drain hole is obliquely arranged from the water intercepting groove to the outside of the reducing groove box body, so that rainwater in the water intercepting groove can be drained from the drain hole more easily.
Optionally, the inclination angle of the drain hole is 20-45 °.
The drain hole with the inclination angle of 20-45 degrees can enable rainwater in the water intercepting groove to be drained more easily, and reduce the probability of rainwater accumulation in the water intercepting groove, thereby reducing the adverse effect of the rainwater on the cable.
Optionally, the bottom of the reducing groove box body is also provided with a plurality of lifting convex strips.
Through setting up the lifting sand grip, can carry out interception layer by layer to the rainwater, can further intercept on the one hand and get into this internal rainwater of reducing groove box, reduce the probability that the rainwater further stretchs, on the other hand also can be with the certain height of this internal cable lifting of reducing groove box, reduce the probability of cable and the this internal rainwater contact of entering reducing groove box to the protection cable prolongs the life of cable.
Optionally, the cross section of the lifting convex strip is an arc-shaped surface.
The cross-section of lifting sand grip is the arcwall face for the cable is more mild with the contact of lifting sand grip, reduces the wearing and tearing that the lifting sand grip produced the cable, thereby further prolongs the life of cable.
Optionally, the height of the lifting convex strip is 0.3-1.2 cm.
The lifting convex strips with the height of 0.3-1.2cm can meet the requirements of intercepting rainwater and lifting cables, and the space inside the reducing groove box body cannot be occupied too much, so that the reducing groove box body is ensured to have enough space to accommodate the cables.
Optionally, the distance between adjacent lifting ribs is 1-2 cm.
So design, can enough let the lifting sand grip in the reducing groove box body have certain density, guarantee the bearing of lifting sand grip to the cable, supporting role, can not be because of the too close too much incremental cost that sets up of lifting sand grip again.
