Embodiment Construction
[0024] The present invention is further illustrated by specific examples below.
[0025] like Figure 1~Figure 3 As shown, a construction method of a deep foundation pit earthwork ramp, comprising:
[0026] Step 1. Ramp monitoring: According to the design drawings of the ramp, select the monitoring point of the foundation pit, complete the layout before the construction of the ramp, and collect the initial data; the monitoring frequency is from complex to simple, three days before the ramp is put into use, Three times a day in the morning, noon and evening; from the third to fourteenth days, once a day; after two weeks, once every three days, the monitoring time should continue until the ramp is removed;
[0027] Step 2. Ramp construction and initial grinding: Backfill the earthwork according to the designed ramp positioning and slope, starting from the bottom of the foundation pit, backfilling in layers and compacting in layers. During the backfilling process, an excavator c...
