Preferably, one end of the drainage groove seat is provided with a slot, and one end of the support plate is inserted into the slot.

Preferably, the drainage groove seat is of a U-shaped groove structure, fixing holes are formed in two sides of the drainage groove seat, and the lower surface of the drainage groove seat is provided with an inserted rod.

Preferably, the clamping groove is of an L-shaped groove structure.

Compared with the prior art, the beneficial effects of the utility model are that:

the utility model provides a drainage device for subway foundation ditch, when being under construction, put into the trench that digs with a plurality of drainage groove seat neatly and continuously, and insert the inserted bar bottom the trench, then insert the bottom of backup pad in the slot, the both sides of filter sieve are inserted in the draw-in groove, then cover the drainage groove seat through the upset apron, wear out the fixed orifices and squeeze into the mounting hole that reserves in the ground again with fixing bolt, can accomplish the installation and the fixed to the device; the accumulated water flows into the drainage groove seat from the drainage hole, the filter screen and the blocking net can filter out fixed garbage in the accumulated water, the cover plate is opened at intervals, the pull ring is pulled upwards, the filter screen and the blocking net are pulled out of the drainage groove seat, and then the garbage in the drainage groove seat is cleaned out, so that the situation that the drainage pipeline is blocked by the garbage is effectively avoided.

The utility model provides a drainage device for subway foundation ditch, backup pad provide the fixed stay for the filter sieve, have increased the bearing capacity of filter sieve, have reduced the breakage rate of filter screen, have prolonged the life of filter sieve.
