Pipe well dewatering construction method

The invention relates to a pipe well dewatering construction method. The method comprises the following steps: determining an area needing to be dewatered, setting an ideal effective water outlet length of water filter pipes, calculating a total water outlet amount and a single-well water outlet amount, determining the number of dewatering wells, and establishing a simulation model; carrying out dewatering simulation on the simulation model in foundation pit dewatering simulation software; when a dewatering process reaches a stable state, extracting a dewatering depth; if the dewatering depthmeets a dewatering need, extracting actual effective water outlet lengths of the water filter pipes; and if the actual effective water outlet length of one water filter pipe is different from the ideal effective water outlet length of the water filter pipes, adjusting the ideal effective water outlet lengths of the water filter pipes, re-calculating the single-well water outlet amount and adjusting the number of the dewat
