Special-shaped cross section surge shaft with reversely-suspended sluice chamber
The invention discloses a special-shaped cross section surge shaft with a reversely-suspended sluice chamber. A surge shaft mineshaft is arranged on the upper portion of the surge shaft, the surge shaft mineshaft is formed by intersection of a cylinder and a column with the sector-shaped cross section, the cross section of the surge shaft mineshaft is structurally formed by sequentially connectinga left arc, one straight line section, a right arc and the other straight line section end to end, the radius of the left arc is smaller than that of the right arc, an external corner is arranged atthe joint of one straight line section and the left arc, and an internal corner is arranged at the joint of the other straight line section and the right arc. A diversion tunnel is formed in the position, in front of the surge shaft mineshaft, of the lower end of the surge shaft mineshaft, and a power tunnel is arranged behind the surge shaft mineshaft. The reversely-suspended sluice chamber is dug behind the lower end of the surge shaft mineshaft, and a reversely-suspended sluice chamber dome of the reversely-suspended sluice chamber is a hyperbolic dome protruding outwards. A traffic tunnelis further formed in the reversely-suspended sluice chamber. According to the surge shaft, the excavating and lining engineering amount is reduced on the premise of meeting the functional requirements, and the surge shaft is an innovation and optimization on the basis of a traditional round surge shaft.
本发明公开了一种含倒悬闸室的异形断面调压井，其上部为调压井井筒，调压井井筒由圆柱与横截面为扇形的柱体相交而成，调压井井筒的横截面结构为：由一条左圆弧、一条直线段、一条右圆弧和另一条直线段依次首尾相连接而成，且左圆弧的半径小于右圆弧的半径，直线段与左圆弧相接处为阳角，直线段与右圆弧相接处为阴角；在调压井井筒的下端，调压井井筒前方具有引水洞，后方具有发电洞；在调压井井筒下端后方扩挖有倒悬闸室，倒悬闸室的倒悬闸室穹顶为向外凸出的双曲穹顶；在倒悬闸室内还具有交通洞。本发明调压井在满足功能需求的前提下减少了开挖及衬砌工程量，是在传统圆形调压井基础上的一种革新和优化。
