山区建筑常采用纵横错层、掉层等处理方法,因此产生了室内堡坎墙。堡坎墙既是内墙又是挡土墙,要采取措施,防止地下水侵入建筑物内部。全封闭、无排水条件的地下室,多采用卷材防水、混凝土防水、刚性抹面防水等以防为主的方案;而有排水条件者则应以排为主。以排为主的做法是:把堡坎墙移至室外,与室内墙形成一道排水防潮的空间,两墙净距60cm(为利用空间,在结构允许的情况下,净距可增大至2m),在此空间内做好地下水的排除和通风,使室内保持干燥(图1、2)。室内墙内外两面应分别处 Mountain buildings often use vertical and horizontal layers, layers, etc., resulting in an indoor fortification wall. The fortification wall is both an internal wall and a retaining wall. Measures should be taken to prevent groundwater from intruding into the interior of the building. Fully-enclosed, non-drainage basement, more use of membrane waterproofing, concrete waterproof, rigid plaster waterproof, etc. to prevent the main program; and those who have drainage conditions should be dominated by platoons. The platoon-based approach is to move the wall of the fort to the outside and form a space for drainage and moisture prevention with the interior wall. The distance between the two walls is 60cm (for space utilization, the space can be increased to 2m when the structure permits. ) In this space, do a good job of removing and venting the groundwater and keep the interior dry (Figures 1, 2). Interior and exterior walls of the interior wall should be separated
