Foundation pit permanent precipitation structure
The invention discloses a permanent dewatering structure of a foundation pit, and belongs to the technical field of municipal foundation pit dewatering. The structure comprises a foundation pit body, an intercepting ditch is arranged in the foundation pit body, and a supporting blind ditch is arranged at one end of the intercepting ditch. The problem of water seepage in an existing foundation pit is solved, one side of the interior of the foundation pit body is provided with the medium sand inverted filter layer, the outer side of the medium sand inverted filter layer is close to a nearby natural river channel, and underground water around the foundation pit body enters the intercepting ditch and then is drained into the nearby natural river channel through the supporting blind ditch, so that the surrounding underground water is intercepted; therefore, salinization of the greening objects and the planting soil caused by underground water is greatly reduced, and the survival rate and the growth environment of the greening objects are guaranteed; and secondly, the medium sand inverted filter layer is utilized to ensure that seepage water cannot take away soil in the dam body or the foundation pit body when flowing out, so that piping and soil flowing can be prevented, and the purposes that underground water flows smoothly and fine particles in the soil are not lost are achieved.
本发明公开了一种基坑永久降水结构，属于市政基坑降水技术领域。本发明包括基坑本体，所述基坑本体内设置截水沟，截水沟一端设有支撑暗沟。本发明解决了现有基坑内部渗水的问题，基坑本体内部的一侧设置有中砂反滤层，而中砂反滤层的外侧靠近附近自然河道，基坑本体四周的地下水进入截水沟内部后，再经由支撑暗沟引流至附近自然河道中，以此对四周的地下水进行截留，从而大大降低了地下水对绿化物和种植土的盐碱化，保证了绿化物的成活率和生长环境；其次靠近利用中砂反滤层保障渗透水流出时带不走堤坝体或基坑本体中的土壤，从而可防止管涌和流土的发生，以达到地下水流畅通而土壤中细颗粒不流失的目的。
