A architectural engineering area technology controllable a well lamination construction, including: (1) falls water well use two section or more strainer designs, in the diving water-bearing stratum and the bearing pressure water-bearing stratum has the strainer separately; (2) in the well, between the diving water-bearing stratum and in bearing pressure water-bearing stratum's section of well tubes installs stops the water installment controllably; when (3) tenth well constructs, outside between well tube's wall and the opening wall, the diving water-bearing stratum and the bearing pressure water-bearing stratum's aquiclude place establishment stops the water section; when (4) precipitation construction, carries on the diving unwater precipitation first, when in has the dangerous depth which structure excavation to the confined water produces wells up suddenly, opens in the well to stop the water installment, the extraction confined water, and may continue to the diving water-bearing stratum to carry on the unwater precipitation; In the pump process, in the well stops the water installment to open repeatedly and to close, realizes to the precipitation level, the precipitation process, the precipitation degree control. This invention uses a well to solve the diving unwater and the confined water voltage dropping or the unwater question.
