Construction method for well point dewatering
The invention provides a construction method for well point dewatering. The construction method comprises the following steps of (1) according to a design drawing for the well point dewatering, measuring and paying off at the construction site, and determining the well drilling location, channel position and horizontal elevation of a well point; (2) adopting a well drilling machine to drill a well hole with design depth at the determined well drilling position; (3) excavating and paving the channel of a well point pipeline; (4) paving the pipeline in the well hole, putting a well point pipe of which the bottom end is provided with a deformable pipe-shaped filtering assembly into the well hole, and fixing the bottom end of the well point pipe to the design depth; (5) expanding and opening the deformable pipe-shaped filtering assembly, and tightly attaching the deformable pipe-shaped filtering assembly to the wall of the well hole, so as to realize the functions of supporting the wall of the well hole and filtering; (6) installing a water suction pump, paving a water delivery main pipe, and connecting the water outlet end of each well point pipe and the water delivery main pipe, so as to perform the water suction construction. The construction method has the advantages that the underground water can be smoothly drained out, and the sand and slit are blocked into the well hole.
