Adjustable underground curtain suitable for coastal underground reservoir and construction method of adjustable underground curtain
The invention provides an adjustable underground curtain suitable for a coastal underground reservoir and a construction method of the adjustable underground curtain. According to hydrogeological conditions of a coastal area, related areas such as underground fresh water and seawater invasion are determined; according to the seawater invasion area, the construction position of the adjustable underground curtain is selected, the adjustable underground curtain needs to be completely cut off the seawater invasion area, the upper portion of the adjustable underground curtain is built to the ground surface, the bottom of the adjustable underground curtain is built to the bottom layer impermeable bedrock, and the underground curtain wall is slightly higher than the highest sea level of the local sea level; the adjustable underground curtain comprises fixed underground walls and adjustable gates, and the adjustable gates and the fixed underground walls are distributed alternately. By means of the technical scheme, the opening size of the underground curtain gate is adjusted in real time, seawater backflow type invasion in the dry season is prevented, and soil salinization in the coastal area in the wet season is avoided.
本发明提供了一种适用于滨海地下水库的可调式地下帷幕及其施工方法，根据滨海地区的水文地质条件，确定地下淡水及海水入侵等相关区域；根据海水入侵区域，选择可调式地下帷幕建设位置，可调式地下帷幕需完全切断海水入侵区域，可调式地下帷幕上部修建至地表，底部修建至底层不透水基岩，地下帷幕墙体的高度略高于当地海平面最高潮位；可调式地下帷幕包括固定的地下墙和可调式的闸门两部分，可调式的闸门与固定的地下墙相间分布。通过本发明的技术方案，实时调整地下帷幕闸门的开口尺寸，防止枯水期海水倒灌式入侵，避免丰水期滨海地区土壤盐渍化。
