A construction site trolley comprises a trolley hopper, a pushing handle, supports, wheels, springs a, air cylinders a, a connecting frame, an air pipe, springs b, air cylinders b, a connecting rod and an air pump. The pushing handle is fixedly installed on the rear end face of the trolley hopper, the two supports are fixedly installed on the lower end face of the trolley hopper, the wheels are located between the two supports, and the two sides of each wheel are hinged to two connecting rods respectively. The two connecting rods are respectively hinged with the two supports; each connecting rod is fixedly connected with the telescopic rod end of one air cylinder a; a telescopic rod of each air cylinder a is sleeved with a spring a. When the two springs a and the springs b are released, telescopic rods of the air cylinders a and the air cylinders b extend to drive the trolley to bounce upwards, and the trolley can bounce when the trolley passes through a concave-convex road surface orsome obstacles exist on the road surface, so that the trolley can pass through the obstacles on the concave-convex road surface or the road surface more easily.
