大da棚peng建jian好hao後hou，棚peng牆qiang坍tan塌ta是shi常chang有you的de事shi兒er。細xi心xin的de菜cai農nong會hui發fa現xian，棚peng牆qiang坍tan塌ta多duo從cong大da棚peng後hou砌qi開kai始shi。可ke見jian，做zuo好hao大da棚peng後hou砌qi的de防fang護hu工gong作zuo至zhi關guan重zhong要yao。調tiao查zha中zhong，記ji者zhe了le解jie到dao，造zao成cheng大da棚peng後hou砌qi坍tan塌ta的de原yuan因yin有you很hen多duo，需xu找zhao對dui原yuan因yin有you針zhen對dui性xing的de防fang護hu才cai對dui，下xia麵mian咱zan們men就jiu來lai分fen析xi一yi下xia。

，大da棚peng後hou砌qi外wai側ce的de後hou坡po沒mei做zuo好hao防fang雨yu保bao護hu。對dui於yu大da棚peng後hou砌qi外wai側ce的de後hou坡po，菜cai農nong為wei防fang雨yu常chang為wei其qi披pi上shang一yi層ceng薄bo膜mo

，長chang期qi使shi用yong後hou也ye難nan免mian會hui有you破po洞dong

，漏lou入ru雨yu水shui，從cong而er造zao成cheng後hou砌qi坍tan塌ta。因yin此ci
，建jian大da棚peng在zai後hou坡po上shang覆fu土tu時shi，表biao層ceng20厘米的土壤最好摻入不低於三分之一的石灰粉，這樣後坡就不會漏水了。
