Foundation pit dewatering system and method for coastal sandy soil area
The invention discloses a foundation pit dewatering system and method in a coastal sandy soil area, the foundation pit dewatering system comprises a plurality of dewatering wells arranged around a foundation pit on the peripheral side of the foundation pit, suspension water pumping devices suspended in the dewatering wells are arranged in the dewatering wells, and each suspension water pumping device comprises a suspension block floating on the water surface; a protective net cylinder is hung at the bottom of the suspension block through a rope, a water suction pump is fixed in the protective net cylinder, supporting legs are arranged at the bottom of the protective net cylinder, and pressure sensors are arranged at the bottoms of the supporting legs; a filtering sleeve is arranged in the dewatering well, an end cover is arranged at the outer end of the filtering sleeve, and a penetrating hole for a conveying pipe on the water suction pump to penetrate through is formed in the end cover. The device further comprises a vacuumizing unit, the vacuumizing end of the vacuumizing unit is communicated with each filtering sleeve through a vacuumizing pipe, and an inner cavity of each filtering sleeve is vacuumized. Through the negative pressure vacuum effect, the water seepage effect of the dewatering well is improved, and therefore a large amount of water is prevented from seeping into the foundation pit.
本发明公开了一种沿海砂土地区的基坑降水系统及方法，包括在基坑的周侧设置环绕基坑设置的多个降水井，所述降水井内设有悬浮在降水井内的悬浮抽水装置，所述悬浮抽水装置包括漂浮在水面上的悬浮块，所述悬浮块的底部经绳索悬挂有防护网筒，所述防护网筒的内部固定有抽水泵，所述防护网筒的底部设有支撑脚，且所述支撑脚的底部设有压力传感器；所述降水井内设有过滤套管，所述过滤套管的外端部设有端盖，且所述端盖上设有供抽水泵上的输送管穿过的穿孔；还包括抽真空机组，所述抽真空机组的抽空端经抽空管与每个过滤套管连通，且对每个过滤套管的内腔进行抽真空；本发明过负压真空的作用，提高了降水井的渗水作用，从而避免基坑内渗入有大量的水体。
