Limit card board is connected to, connecting groove is offered at the manhole cover body lower surface edge, load is provided with below the walling crib inwall
Plate, and carry on a shoulder pole plate upper surface and be provided with elastomeric pad.
As further describing for above-mentioned technical proposal：
The fixing groove offers four altogether, and four fixing grooves are mutually right on outer well fixed plate center line between any two
Claim.
As further describing for above-mentioned technical proposal：
The elastomeric pad is provided with two altogether, and two elastomeric pads are symmetrical on load plate level center line.
As further describing for above-mentioned technical proposal：
The thickness of the elastomeric pad is 10mm.
As further describing for above-mentioned technical proposal：
