Underground water multi-layer high-pressure recharge system and construction method thereof
The invention belongs to the technical field of recharge well construction, and discloses an underground water multi-layer high-pressure recharge system and a construction method thereof. The underground water multi-layer high-pressure recharge system comprises a well casing, a sealing water blocking device and a recharge pipe, the well casing is arranged in a soil layer, the soil layer comprises a plurality of waterproof soil layers and a plurality of to-be-recharged confined water and soil layers, one to-be-recharged confined water and soil layer is arranged between every two adjacent waterproof soil layers, a plurality of groups of water through holes are formed in the pipe wall of the well casing, and a plurality of groups of water through holes are formed in the pipe wall of the well casing. And each group of water through holes is communicated with one layer of confined water and soil layer to be recharged. The sealing water blocking device is arranged in the well pipe, the sealing water blocking device comprises two sealing water blocking pieces, the two sealing water blocking pieces block the two ends of one set of water through holes respectively, and the sealing water blocking device can move in the well pipe so as to block the two ends of the other set of water through holes. The recharge pipe is configured to inject recharge water between the two sealing water blocking pieces. Multi-layer recharge of the same recharge well is achieved, and recharge water can be prevented from emerging out of the ground from the well casing.
本发明属于回灌井施工技术领域，公开了一种地下水多层高压回灌系统及其施工方法。该地下水多层高压回灌系统包括井管、密封阻水装置和回灌管，井管设置于土层中，土层包括多层隔水土层和多层拟回灌承压水土层，相邻两层隔水土层之间夹设一层拟回灌承压水土层，井管的管壁上设置有多组通水孔，每组通水孔与一层拟回灌承压水土层相连通。密封阻水装置设置于井管内，密封阻水装置包括两个密封阻水件，两个密封阻水件分别封堵于一组通水孔的两端，密封阻水装置能够在井管内移动，以封堵于另一组通水孔的两端。回灌管被配置为向两个密封阻水件之间注入回灌水。本发明实现了对同一回灌井的多层回灌，且能够避免回灌水从井管冒出地面。
