Waste treatment device for civil engineering construction

The invention discloses a waste treatment device for civil engineering construction. The waste treatment device comprises a containing device, and a feeding device is arranged at the top of the containing device. Through cooperation of a crushing device, a driving device and a retracting device, the distance between a right crushing roller and a left crushing roller can be automatically increased when the waste treatment device for civil engineering construction encounters objects which cannot be crushed, so that the objects which cannot be crushed leak out, time delay caused by the fact that the waste treatment device for civil engineering construction is jammed by the objects which cannot be crushed is avoided, further improvement of treatment efficiency is facilitated, meanwhile, crushing teeth on the right crushing roller and the left crushing roller are prevented from being damaged, and the service life of the right crushing roller and the left crushing roller is prolonged; through cooperation of the con
