Underground dewatering construction method, dewatering well dewatering construction structure and plugging construction structure
The invention discloses an underground precipitation construction method, which comprises a precipitation well precipitation construction step and a precipitation well plugging construction step, and the precipitation well precipitation construction step comprises the following sub-steps: manufacturing a well casing, forming a water permeable hole in the lower section of the well casing, and arranging a water bag tightener on the upper section of the well casing; digging a dewatering well on the stratum, enabling the dewatering well to extend below the bottom plate of the underground structure, lowering the well casing into the dewatering well, enabling the water permeable hole to be positioned below the bottom plate of the underground structure and the water bag loosening and tightening device to be positioned above the bottom plate of the underground structure; backfilling the periphery of the well casing with a filter material; and the silt accumulation prevention deep water pump connected with the water pipe is lowered to the bottom of the well casing, and the water pipe penetrates through the water bag tightener to extend to the ground. The invention further discloses a dewatering construction structure and a plugging construction structure of the dewatering well. According to the local descending water construction method, the dewatering well dewatering construction structure and the plugging construction structure, confined water is prevented from puncturing an underground structure bottom plate and emerging out of a well mouth, the phenomenon of base piping is avoided, and the grouting plugging efficiency and quality are improved.
本发明公开了一种地下降水施工方法，包括降水井降水施工步骤和降水井封堵施工步骤，所述降水井降水施工步骤包括如下子步骤：制作井管，在井管下段开设透水孔，在井管上段设置水囊松紧器；在地层上开挖降水井，使降水井延伸至地下结构底板以下，将井管下放至降水井中，使透水孔位于地下结构底板以下及水囊松紧器位于地下结构底板以上；在井管四周回填滤料；将连接有水管的防积淤深水泵下放至井管底部，并使水管穿过水囊松紧器延伸至地面。还公开了种降水井降水施工结构及封堵施工结构。本地下降水施工方法、降水井降水施工结构及封堵施工结构防止承压水击穿地下结构底板及冒出井口，避免产生基底管涌现象，提高注浆封堵效率和质量。
