The invention discloses a concrete steel fiber double-layer reinforced well lid, which comprises a base and latches. By arranging a buffer device, when pressure is applied to a first cover plate, a first well lid body applies pressure to a top plate to enable a connecting rod to push two first sliding blocks to move in a first sliding groove, the first sliding blocks are pulled through the effectof second springs, thus the first well lid body achieves the buffer effect, and the damping effect is good, so that dangers caused by damage to the first well lid body are avoided. By arranging a threaded sleeve, a threaded rod is driven to rotate by rotating a nut, thus the threaded rod can pull up a second well lid body through the threaded sleeve, operating is convenient, the drainage speed canbe increased, and water flow blocking is avoided. By arranging a locking device, the well lid is not opened by rainwater and manual work through clamping of the latches and grooves, the fixing effectis good, and the various dangers are reduced effectively. The concrete steel fiber double-layer reinforced well lid is simple in structure and convenient to operate, and has the advantages of good fixing effect and good damping.
