1.地下结构物防水变形缝矿井建筑结构如受煤坑、半地下储煤仓、各种运输机走廊和暗道等,由于工艺需要,经常设置于地下,基底标高有时达到地表下10米左右,部分结构经常受到地下水的作用,有时甚至整个经构物处于地下水之中。这类防水变形缝的设计,过去大都是采用预埋式或可卸式的V形止水镀锌钢板的作法,建工部的《地下建筑物和结构物防水设计技术措施(试行草案)》會作了较详细的介绍,但缺乏大样图。由于该试行草案对各变形缝在结构物上下的顶底板和左右两侧墙的转角处采用V形止水镀锌纲板及∠90 × 130×
1. Underground structures Waterproof deformation seam Mine construction such as by the coal pit, semi-underground coal storage, corridors and various transport corridors, etc., due to process needs, often set in the ground, the substrate elevation sometimes up to 10 meters below the surface, some The structure is often affected by groundwater, and sometimes even the entire structure is in groundwater. In the past, the design of such waterproof deformation joints adopted the practice of embedded or detachable V-shaped water-stop galvanized steel plates. The Technical Measures for Waterproof Design of Underground Buildings and Structures (Draft for Trial Implementation) of Construction Department Will make a more detailed introduction, but the lack of big picture. As the draft draft of the deformation of the seam at the top and bottom of the structure of the top and bottom walls and left and right corner of the wall with V-shaped galvanized water board and ∠ 90 × 130 ×
