Plugging drainage device for dewatering well and construction method
The invention relates to the technical field of dewatering construction, in particular to a dewatering well plugging drainage device and a construction method. The construction method comprises the following construction steps that backfilling is conducted in the precipitation well, redundant underground water is pumped, a plugging sleeve is installed at the top of the precipitation well, the plugging sleeve is fixedly connected with a pouring belt through a water stop ring, and a first plugging steel plate is installed in the plugging sleeve; in the process of installing the first plugging steel plate, water is continuously pumped in the dewatering well through a water pump, the water pump is removed, concrete is poured in the upper side area of the first plugging steel plate, a second plugging steel plate is installed at the top of the plugging sleeve, and the airtightness of plugging of the bottom of the dewatering well is detected. According to the construction method, plane operation is changed into three-dimensional operation, the problems of urgent surge in the precipitation well plugging process and underground water leakage in the later period are reduced, the quality of the plugged precipitation well is improved, and it can be guaranteed that engineering construction is completed on schedule during various emergency construction periods and basement three-dimensional operation.
本发明涉及降水施工的技术领域，尤其是涉及一种降水井封堵排水装置及施工方法。本发明施工方法包括以下施工步骤，在降水井内进行回填，并抽取多余地下水，在降水井顶部安装封堵套筒，所述封堵套筒通过止水环与浇筑带连接固定，在封堵套筒内安装第一封堵钢板，安装第一封堵钢板过程中通过抽水泵对降水井内进行持续抽水，拆除抽水泵，在第一封堵钢板上侧区域浇筑混凝土，并在封堵套筒顶部安装第二封堵钢板，检测降水井底部封堵的气密性。本发明施工方法将平面作业改为立体作业，减少了降水井封堵过程中“急涌”现象的产生以及后期地下水外渗的问题，提高了封堵降水井的质量，在各种抢工期、地下室立体作业时，能保证工程按期施工完成。
