[0010] Preferably, the tops of the ends of the reinforcing rods on both sides are provided with circular grooves for placing bolts and nuts, and the tops of the bolts and nuts are provided with hexagonal grooves.

[0011] Preferably: a baffle for limiting the lateral position of the partition strips is welded on the top of the support ring, and both ends of each group of the partition strips are inserted between two groups of baffles.

[0012] Preferably, the filter assembly comprises a filter plate and a bottom ring, the bottom of the outer frame is integrally formed with an inverted bottom ring, and a diamond-shaped grid-shaped metal filter plate is welded to the top of the bottom ring.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. In the utility model, the filter assembly can filter larger debris or garbage to prevent the garbage from clogging the subsequent dredging pipes, or prevent valuables from falling into the waterway and being lost, etc., and the top structure of the steel grating is easy to disassemble, so that the impurities on the top of the filter assembly can be cleaned.

[0015] 2. In the utility model, by setting a plurality of groups of anti-skid grooves arranged at equal distances, it is possible to prevent workers from slipping when walking on the top of the steel grating.
