Embodiment Construction
[0038] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0039] See attached figure 1 And attached Figure 8 , a construction method for deep well point dewatering, using a new type of deep well point dewatering equipment. The deep well point dewatering equipment includes a dewatering well pipe 1 and a dewatering device 2, so that the installation of the dewatering well pipe 1 is relatively simple, and the quality of the dewatering well pipe 1 installed in the well hole is more ideal.
[0040] See attached figure 1 , a dewatering well pipe 1, comprising a plurality of unit well pipes 11 and a filter screen 13 at the bottom of the dewatering well pipe 1.
[0041] See attached figure 2 And attached image 3 The lower end of the inner wall of the unit well pipe 11 has a first installation ring platform 111, and at least three T-shaped protrusions 111a are evenly distributed in the circumferential direction on th...
