Construction method of submersible dewatering well under alluvial plain geological condition
The invention discloses a construction method of a submersible dewatering well under alluvial plain geological conditions, which comprises the steps of determining a well position, embedding a pile casing, placing a drilling machine in place, drilling by the drilling machine, placing a well pipe, backfilling a well hole and placing a water pump, the well pipe is formed by welding a corrugated pipe and a steel pipe, a plurality of drainage holes are regularly distributed in the outer wall of the well pipe, and a steel wire mesh is wrapped outside the well pipe; 3-4 layers of nylon nets are wrapped outside the steel wire net, two layers of filter nets are arranged at the bottom of the well pipe for wrapping, the joint of the corrugated pipe and the steel pipe is wrapped by two layers of filter nets, bamboo chips are clamped outside the joint, then the bamboo chips are bundled by lead wires, and finally, the well pipe is placed into a drilled well hole through a truck crane. The outer side of the well pipe is coated with a steel wire mesh firstly, then secondary coating is conducted through a nylon net, the whole rigidity strength of the well pipe can be enhanced while the well pipe meets the filtering effect, finally, the well pipe is formed by welding a corrugated pipe and a steel pipe, the impact strength of the well pipe is improved, and the service life of the well pipe is prolonged. And the well casing is not easy to damage.
本发明公开了一种冲积平原地质条件下潜水降水井的施工方法，包括确定井位、埋设护筒、钻机就位、钻机钻孔、井管放置、井孔回填和水泵放置，井管采用波纹管和钢管焊接形成，井管的外壁上规则分布有若干泄水孔，且井管外包钢丝网，钢丝网外包3‑4层尼龙网，井管的底部设置有两层滤网进行包覆，波纹管和钢管的接头处用两层滤网包裹并外夹竹片，竹片再用铅丝捆扎，最后再通过汽车吊将井管放入打好的井孔中。本发明还通过在井管的外侧先通过钢丝网包覆，再通过尼龙网进行二次包覆，实现了井管在满足过滤效果的同时还能增强井管整体的钢性强度，最后通过将井管设置为波纹管和钢管焊接形成，提高了井管的抗冲击强度，而且还能使得井管更不易出现破损。
