Study and application of calculation method on land subsidence caused by well - point dewatering 井点降水引起地面沉降的简便计算方法研究及应用
Calculation analysis on relation of non - ruled arrangement of well point for water lowering and ground surface subsidence 非规则排列的井点降水与地面沉降计算分析
The well point should pump water continually , the normal pumping rule is " big then small , feculent then clear " 井点应连续不断的抽水,正常出水规律为"先大后小,先混后清"
Application of dewatering system with self drainage deep well and light well points to deep foundation pit under sandy soil condition 自流深井配轻型井点降水在砂质土深基坑中的应用
Adopt " water - jet " method to embedded well point pipe . connect to the water - collect main line while the well point pipe is in the position 采用"射水法"埋设井点管.井点管下沉到位后,与集水总管连接
During the hole precipitation of the base , the precipitation technology of the perpendicular well is a kind of precipitation technology that is adopted extensively at present 在基坑降水中，垂直井点降水技术是目前广泛采用的一类降水技术。
Construct the light well point pipe after completion the east two - line side piling , to prevent the pipe movement or damage by soil pressure during piling 轻型井点管应在东侧的两排边桩施工完毕后方可施工,防止压桩过程中,土的挤压力使井管位移或损坏井管
Abstract : the method to lowering ground water level is introduced which combines shallow - water well with deep - water well in well point . the paper also provides practical experience for future work 文摘:阐述了轻型井点与深井井点二种形式相结合的降水法在实践中的应用，为将来大面积降水提供实践经验
Based on the new technique of vacuum deep wellpoint developed in recent 10 years and the actual conditions in the well water exclusion of foundation pits , a new method for evaluation volume of water was brought forward 摘要针对近十年发展起来的井管内抽真空的深井井点新工艺，根据它在四周有良好隔水的基坑中降水的实际情况，提出了一种水量估算和井点设计的新方法。
In the construction of the underground pavement - wuhan qingnian road ( the west beihu road ) , the well - precipitation is adopted to evaculate the penetrating water in the pavement field and the up level stagnation water , which consolidates the ground and 1ars a working condition without water 摘要武汉市青年路（北湖西路）地下人行地道工程施工中，为了疏干通道土层范围内的潜水及上层滞水，固结地层为施工创造无水作业环境，采用了洞外井点降水。
