摘　　要：DMG基底孔压疏导调节系统可有效调节及控制建筑物抗浮水位的标高,并与侧壁截排水系统、应急减压系统共同组成抗浮减压系统,以便在极端天气下达到快速疏水的作用,有效防止抗浮构件疲劳拉伸失效,延长建筑寿命;同时该系统施工简单、施工速度快,无需大型机械辅助即可用于各种底板的施工。本项目运用DMG基底孔压疏导调节系统解决了场地狭小、基坑深度深、锚杆机无法进出、锚杆工序烦琐、施工时间长等问题,适用于不便使用增加结构自重及桩锚抗浮的情况。The DMG base pore pressure drainage and regulation system can effectively regulate and control the elevation of the building's anti floating water level,and together with the side wall interception and drainage system and emergency pressure reduction system,form an anti floating and pressure reduction system to achieve rapid drainage in extreme weather,effectively prevent fatigue and tensile failure of anti floating components,and extend the building's lifespan.At the same time,the system has simple construction and fast construction speed,and can be used for various bottom plate construction without the need for large-scale mechanical assistance.This project uses the DMG base pore pressure dredging and adjustment system to solve problems such as narrow site,deep foundation pit depth,inability of anchor bolt machines to enter and exit,cumbersome anchor bolt process,and long construction time.It is suitable for situations where it is inconvenient to use,increase the structural weight,and pile anchor resistance to floating.
