The invention provides a spiral upper chamber surge shaft structure with an impedance hole. The spiral upper chamber surge shaft structure comprises a shaft body arranged at the tail end of a diversion tunnel and further comprises a spiral upper chamber, a traffic hole and a overhaul platform; a vertically extending gate hole is formed in the shaft body; the gate hole respectively communicates with the diversion tunnel and the shaft body and is used as the impedance hole; the spiral upper chamber communicates with the shaft body; the overhaul platform is arranged at the top of the shaft body;the traffic hole is Y-shaped and respectively communicates with the spiral upper chamber and the overhaul platform; and a water blocking wall is further arranged at the communication position of the spiral upper chamber and the traffic hole. The spiral upper chamber surge shaft structure has the beneficial effects that in combination with water flow characteristics, the combined structure of the shaft body and the spiral upper chamber is adopted, the overall height of a surge shaft is effectively reduced, the surge shaft arrangement problem is solved, construction is convenient, and the construction period is short.
本发明提供了一种带阻抗孔的螺旋上室调压井结构，包括设置在引水隧洞末端的井筒本体，所述井筒本体内设有竖向延伸的闸门孔，所述闸门孔分别与引水隧洞、井筒本体相连通，并用作阻抗孔；还包括螺旋型上室、交通洞和检修平台，所述螺旋型上室与井筒本体相连通；所述检修平台设置在所述井筒本体的顶部；所述交通洞呈Y型，分别与螺旋型上室、检修平台相连通；在所述螺旋型上室与交通洞的连通处还设有阻水墙。本发明的有益之处在于，结合水流特性，采用井筒本体与螺旋式上室的组合结构，不仅有效降低了调压井整体高度，解决了调压井布置问题，而且便于施工，工期较短。
