Construction process for blocking precipitation well in riverside water-rich and easy-piping stratum
The invention relates to a construction process for blocking a precipitation well in a riverside water-rich and easy-piping stratum. The construction process comprises the following steps of (1) construction preparation, (2) excavation of soil around a pipe, (3) cutting off of a well pipe, (4) backfilling of filler, (5) concrete pouring and (6) backfilling of a foundation pit. And step-slope excavation is conducted on the periphery of the dewatering well in an open excavation foundation pit mode, after excavation, a dewatering well pipe is cut off, and filling materials are backfilled. By the adoption of the process, pipe blocking is not prone to occurring, tamping can be achieved, and the blocking quality is guaranteed.
本发明涉及一种临江富水易管涌地层降水井封堵施工工艺，包括以下步骤：1)、施工准备→2)、开挖管周土→3)、割除井管→4)、回填填料→5)、浇筑混凝土→6)、基坑回填；将降水井周边以明挖基坑的方式进行放坡开挖，开挖后，割除降水井管，回填填充料。采用本发明工艺不易发生堵管，且能够夯实，保证封堵质量。
