根據施(shi)工(gong)(gong)(gong)地(di)點，條件(jian)不(bu)(bu)同(tong)而不(bu)(bu)同(tong)，建筑工(gong)(gong)(gong)程須全(quan)封(feng)(feng)閉，市(shi)區主要(yao)道路(lu)(lu)或(huo)人(ren)流大的不(bu)(bu)得(de)低于(yu)2.5米，其余(yu)不(bu)(bu)得(de)低于(yu)1.8米，一(yi)般半(ban)封(feng)(feng)閉多見于(yu)市(shi)政(zheng)工(gong)(gong)(gong)程，所謂的半(ban)封(feng)(feng)閉指(zhi)兩面(mian)(mian)(mian)或(huo)三面(mian)(mian)(mian)設(she)立圍擋(dang)，一(yi)面(mian)(mian)(mian)或(huo)兩面(mian)(mian)(mian)開放，便于(yu)施(shi)工(gong)(gong)(gong)機(ji)具材料的進(jin)出。具體(ti)要(yao)怎(zen)么設(she)置根據招標文件(jian)、圖紙、現場環境，施(shi)工(gong)(gong)(gong)組織設(she)計(ji)在保(bao)證安全(quan)的情況下來確定。舉(ju)個(ge)(ge)例子，假設(she)市(shi)政(zheng)工(gong)(gong)(gong)程在鬧市(shi)，一(yi)個(ge)(ge)道路(lu)(lu)維(wei)(wei)修(xiu)工(gong)(gong)(gong)程，半(ban)幅(fu)開放交通，半(ban)幅(fu)維(wei)(wei)修(xiu)，這個(ge)(ge)時候(hou)就需要(yao)全(quan)封(feng)(feng)閉，保(bao)證不(bu)(bu)會有行人(ren)誤入而引發危險。再假設(she)一(yi)條新建道路(lu)(lu)位于(yu)郊區，一(yi)端與(yu)老路(lu)(lu)相接，另一(yi)端為野地(di)，那么只(zhi)需要(yao)在新老路(lu)(lu)交接處(chu)設(she)立單(dan)面(mian)(mian)(mian)的圍墻(qiang)和(he)一(yi)扇門即可，其余(yu)三面(mian)(mian)(mian)可以不(bu)(bu)封(feng)(feng)閉。全(quan)封(feng)(feng)閉圍擋(dang)：將整(zheng)個(ge)(ge)施(shi)工(gong)(gong)(gong)范圍用硬(ying)質材料圍起來，組成全(quan)封(feng)(feng)閉圍墻(qiang)半(ban)封(feng)(feng)閉：有一(yi)面(mian)(mian)(mian)或(huo)多個(ge)(ge)面(mian)(mian)(mian)不(bu)(bu)設(she)圍擋(dang)的，即為半(ban)封(feng)(feng)閉。
