Project site construction sequence?

Familiar with the construction drawing → Look at the planning red line → Check the leveling point → Tower crane foundation construction (set the water collecting ditch) → Measure the original landform elevation → Protect the positioning pile → Install the tower crane (apply for installation) → Release the excavation line → Technical disclosure → Mechanical excavation → Pay-off → Manual excavation leveling → Measure the elevation of the pile head and mark it → Break the pile head → Check the size and strain → Check the geosyncline → Pay-off → Woodworking formwork → Cushion.

Bedding should pay attention to the following issues:

1. Before bedding, control the height, elevation and plane size of the formwork. The soil should not be over-excavated or under-excavated.

2, cushion concrete shipped to the scene or in the process of processing to spot check the slump of cushion concrete, the same as the mixture ratio list.

3. Leave the concrete test block, the mix proportion list of cushion concrete, and the second interview report on the inspection of stones and sand, etc.

4, concrete in construction, to observe the smoothness of the concrete surface, can't call the construction unit darby leveling.

5, when pouring concrete, to consider the standby power supply, standby vibrator and other tools.

6, pouring concrete, supervision generally to stand by.
