Embodiment 1
[0055] The benzene hydrogenation engineering earthwork construction method of the present invention comprises the following steps:
[0056] a. Paying off
[0057] The benzene hydrogenation unit is divided into the first work area and the water treatment facilities, material warehouse, electrical room and central control building are divided into the second work area; the site is leveled; the foundation of the benzene hydrogenation unit is used as the independent platform pile foundation, and the length of the hydrogen compressor room is × width It is 24m×12m, the column distance is 6m, and the span is 12m. The foundation of the factory building adopts pile foundation reinforced concrete independent cap, and the buried depth is -2.000m. The foundation of the reactor heating furnace adopts pile foundation, and the buried depth is -2.000m.
[0058] b. Drainage and precipitation, including:
[0059] (1) When the groundwater level is low and the soil quality is good, set drainage ...
