The invention provides an inspection well lid water sealing lock and belongs to the technical field of urban construction underground pipeline projects. The inspection well lid water sealing lock consists of a plug screw lock, a key and a lifting handle. The plug screw lock consists of a lock body 1, a lock cylinder 2, a large sealing pad 3, a spring washer 4, a nut 5 and a small sealing pad 6. The locking body 1 is installed in a lid hole formed in a well lid G. The lock cylinder 2 is a plug screw lock. The lock cylinder 2 is screwed into or out of a threaded central hole formed in the lock body 1 by using the key, and the well lid G can be locked or opened. The large sealing pad 3 and the small sealing pad 6 are respectively arranged between the locking body 1 and the well lid G and between the lock cylinder 2 and the lock body 1 for sealing. A prism center hole is formed in the key and used for a prism head of the lock cylinder 2 to be inserted therein and enables the lock cylinder 2 to rotate. A threaded rod of the lifting handle is screwed into the threaded central hole formed in the lock body 1, and the well lid G can be lifted and moved. The well lid can be prevented from be stolen, and the congenital defect that ground water flows into an injection well through a lid hole is overcome. The inspection well lid water sealing lock is used for various inspection well lids.
