Anti-seepage structure of old brine salt pan
The invention discloses an anti-seepage structure of an old brine salt pan. The anti-seepage structure comprises a foundation dam body constructed around the old brine salt pan, a foundation trench dug downwards from the top of the foundation dam body, and an anti-seepage layer formed by filling tail salt in the foundation trench and tamping the tail salt, wherein the tail salt at least comprisesgranular sodium chloride, old brine is poured into the anti-seepage layer and at least comprises sodium chloride and magnesium chloride in a saturated state, part of granular sodium chloride in the anti-seepage layer dissolves into the old brine, and a compact sodium chloride crystal structure is formed on the anti-seepage layer. According to the anti-seepage structure of the old brine salt pan provided by the invention, old brine in the old brine salt pan is prevented from permeating outwards through the anti-seepage layer in the foundation trench, and compared with the anti-seepage effect ofblack mud sandwich, the anti-seepage effect of the anti-seepage structure is the same or even better; and salt pan tail salt waste residues are taken nearby, long-distance transportation is not needed, the cost is low, and use is convenient.
本发明公开一种老卤盐田的防渗漏结构，所述防渗漏结构包括围绕老卤盐田构筑的基础坝体、自所述基础坝体顶部向下开挖的基槽、以及在所述基槽中填埋尾盐并夯实形成的防渗层，所述尾盐中至少包括颗粒状的氯化钠，在所述防渗层中浇灌老卤，所述老卤至少包括氯化钠和呈饱和状态的氯化镁，所述防渗层中部分颗粒状氯化钠溶解至所述老卤中，在所述防渗层形成致密的氯化钠结晶体结构。本发明提供的老卤盐田的防渗漏结构通过基槽中的防渗层防止老卤盐田中的老卤向外渗透，与黑泥夹心防渗相比，防渗效果相同甚至更优，而且就近取用盐田尾盐废渣，不需要远距离运输，成本低、使用便利。
