Well water recharge method and well water recharge device

The invention relates to the technical field of recharge well construction, in particular to a well water recharge method and a well water recharge device. The well water recharge method comprises the following steps that S1, a recharge water bag is manufactured; the recharge water bag comprises a water storage part and a water seepage part arranged below the water storage part; s2, the recharge water bag is placed in the recharge well; s3, conveying recharge water; the exhaust hole is opened, the recharge water is filled into the recharge water bag from the water filling opening until the recharge water bag is filled with the recharge water, and the water storage part is tightly attached to the side wall of the recharge well; then, the exhaust hole is closed, recharge water continues to be injected, and water flow seeps towards the periphery of the recharge well from the water seepage part. Water in the recharge well is pressed and conveyed to the periphery of the recharge well through the gravity of the wat
