設備基礎施工方案
一、工程概況：
淀粉車間工程設備較多，施工工藝復雜。 6月25日接到C、D區設備基礎圖紙（白圖）。大塊式設備基礎底部采用C20毛石砼，SJ19.01—1，2、SJ20.01—3.4.5.6、SJ18.01—1.2填夯實，下部采用三、七灰土回填,三、七灰土范圍為設備基礎外邊緣1500mm.由于C、D區的獨立基礎土方在6月23日已開挖完成。在整個土方開挖方案中由于不知道設備基礎的底標高，無法一次性開挖，獨立基礎只有采用點式開挖方案，而對于設備基礎土方只有采用二次開挖。現設備基礎圖有部分圖紙已經下來（白圖），圖紙說明要求，“設備基礎須設備到貨經核對無誤后方可施工”，為提前施工工期，爭得業主同意，按目前白圖施工，特制定本方案。
二、總體施工部署：
按設備基礎下的結構設計，土方開挖分為兩個區域，第一區域開挖有毛石基礎部分，第二區域為開挖有三、七灰土
Equipment foundation program
1, Project Overview:
Starch plant engineering equipment more complicated construction process. June 25 received a C, D District equipment based on drawings (white figure). Massive use of equipment based on the bottom of the C20 rubble concrete, SJ19.01-1, 2, SJ20.01-3.4.5.6, SJ18.01-1.2 fill compaction, the lower part of a three, seven dust-filling, three, seven dust range equipment based on the outer edge of 1500mm. As the C, D District, the independent foundation in June 23 Earthwork excavation has been completed. Programs throughout the earth excavation equipment because they do not know the basis of the bottom elevation, not a one-time excavation, independent foundation excavation program only by point, but only used for the equipment based on the second excavation earthwork. Some devices are based on graph drawing has been down (white diagram), request the drawing, "device to device based on the arrival verified, before construction" for the early construction period, gain the consent of the owners, according to the current white drawings, special development of the program.
Second, the overall construction of the deployment:
Basis according to the structural design of equipment, soil excavation is divided into two regions, the first region based on some of rock excavation and hairy, and the second area for the excavation of three, seven dust
