筒仓沉井基础施工方法

Silo Sunk Shaft Foundation Construction Method

以内蒙神华集团某矿矸石仓基础为例,介绍了筒仓沉井的施工方法,应根据施工工艺及工程情况确定施工方案,然后开始沉井制作,待混凝土强度达到设计要求时,可拆除刃脚架,井筒开始下沉,到达设计位置后,筒壁周围注浆,最后进行封底。施工过程中应注意测量控制、安全控制及下沉过程中对倾斜、位移、扭转的预防及纠正。

Takes gangue storehouse foundation of a mine in Shenhua group of Inner Mongolia as an example,introduces the silo sunk shaft＇s job practice, according to the construction craft and project situation determines plan of construction. Then starts manufacture of the sunk shaft, when the concretes intensity achieves the design require- ments, can dismantle the cutting edge frame, the well chamber starts to sink, after arriving designs the position, around the tube wall grounts, finally carries on the back cover. In the construction process pays attention to prevention and correction for the survey control, the safety control and in the sinking process to inclined, displacement, reverse.
