压力型预应力抗浮锚杆在污水处理池中的应用

Application of Pressure-type Prestressed Anti-floating Anchor in Sewage Treatment Tank

摘要:

以兰溪市某新建工业污水处理厂的生物反应池为例，通过对各种抗浮方案的比选，提出压力型预应力抗浮锚杆的抗浮方案。介绍了在污水处理水池底板到达岩石层时锚杆与底板连接的形式、具体施工阶段抗浮锚杆的检测结果，以及抗浮锚杆自身的抗拔承载力及其与底板锚固时均须满足的相关要求，可为其他类似大型水池抗浮项目提供参考。

Abstract:

Taking the biological reaction tank of a new industrial wastewater treatment plant (WWTP) in Lanxi as an example, the anti-floating scheme of the pressure-type prestressed anti-floating anchor is proposed by comparing and selecting the anti-floating schemes. The form of connection between anchor rods and bottom plate when the bottom plate of the sewage treatment tank reaches the rock layer is described, and the detect results of the anti-floating anchor in the specific construction stage are introduced. Its uplift bearing capacity of the anti-floating anchor must meet the relative requirements when it anchors with the base plate, which can provide the reference for the anti-floating projects of other similar large-scale tank.
