Summary:The invention provides a construction method of a confined aquifer, which belongs to the technical field of building construction and comprises the following steps: S1, digging a groove in a foundation pit; s2, a reinforcement cage is placed in the groove; s3, a dewatering well is dug out of the foundation pit; s4, soil in the foundation pit is cleaned, and the steel pipe is exposed; s5, drilling is conducted, and drilling equipment is connected with the steel pipe; s6, the anchor cable is installed; S7, the sleeve is taken out of the anchor cable hole; grouting is conducted on the interior of the anchor cable hole twice; s8, plugging for the first time; s9, tensioning of the anchor cable is conducted; and S10, second-time plugging is conducted, and the exterior of the anchor cable hole is sealed through a sealing material. According to the scheme, the problem that in the deep foundation pit confined aquifer anchor cable construction process in the prior art, due to the fact that the groundwater amount is lar
