Narrow space deep foundation pit observation well device and construction method
The invention discloses a narrow space deep foundation pit observation well device which comprises a PE pipe body, the PE pipe body is in a round pipe shape, the inner side wall of the PE pipe body is a continuous smooth face, and the outer side wall of the PE pipe body is in a corrugated shape with a convex edge ring. The two side faces, in the length direction of the PE pipe body, of the protruding edge rings are each provided with an inclined face structure so that an isosceles trapezoid can be formed, the ends, close to the PE pipe body, of the protruding edge rings are wider than the ends, away from the PE pipe body, of the protruding edge rings, the outer side of the PE pipe body is wrapped with a first filter screen, the outer side of the first filter screen is wrapped with a second filter screen, and a plurality of water outlet holes are formed in the PE pipe body. The structure is unique, the strength is high, the inner wall is smooth, the frictional resistance is small, the circulation amount is large, the structural strength is high, and the differential settlement resistance is high; the anti-leakage effect is good, and erosion of various chemical media can be resisted; and the underground service life is up to more than 50 years, the device can be recycled for multiple times, the problem that the observation well is difficult to construct in a narrow space is solved, and the device is green, environment-friendly and good in economic benefit.
本发明公开了一种狭窄空间深基坑观测井装置，其包括PE管体，PE管体呈圆管装，PE管体的内侧壁为连续的光滑面，PE管体的外侧壁呈具有凸楞环的波纹形，凸楞环在PE管体长度方向的两侧面分别具有斜面结构从而形成等腰梯形且凸楞环靠近PE管体的一端宽于远离PE管体的一端，PE管体的外侧包有第一层滤网，第一层滤网的外侧包有第二层滤网，PE管体上开有若干出水孔。结构独特，强度高，内壁光滑，摩擦阻力小，流通量大，结构强度高，抗不均匀沉降能力强；抗泄露效果好，可耐多种化学介质的侵蚀；管内不结垢，基本不用疏通，埋地使用寿命达五十年以上，可以多次循环使用，解决了狭窄空间观测井施工难的问题，且绿色环保，经济效益好。
