小山水电站调压井位于发电厂房上游侧的引水洞和压力管道之间，为升管阻抗式调压井，升管为双圆弧复式断面。井体由开挖而成，由于地质条件差，造成了大量超挖。根据调压井断面大、井身高及工期紧的特点，采取无井架液压滑模施工，滑模模体采用单面内壁的钢结构模板。本文就小山水电站调压井采用滑模施工的具体施工情况作一介绍。
Xiaoshan Hydropower Station surge chamber is located in the power plant upstream side of the diversion tunnel and the pressure pipe between the riser impedance surge tank, riser double arc double cross-section. Well body from the excavation, due to poor geological conditions, resulting in a large number of over-excavation. According to the surge shaft section, well height and tight schedule characteristics, take the hydraulic derrick without derrick construction, slipform mold body using single-sided steel structure template. In this paper, Xiaoshan Hydropower Station surge tank using slipform construction of a specific situation for an introduction.
