Get familiar with the construction drawing of cushion layer → look at the planning red line → recheck the bench mark → tower crane foundation construction (set up the collecting ditch) → original landform elevation measurement → protection positioning pile → tower crane (installation) installation → release the excavation line → technical disclosure → mechanical excavation → setting out → manual excavation and leveling → measure and mark the pile head elevation → break the pile head → large and small strain detection → trench acceptance → setting out → woodworking formwork erection → The following problems should be paid attention to: 1
.
The height, elevation and plane size of the formwork should be well controlled before the cushion is laid
.
The soil should not be over excavated or less excavated
.
2
.
When the cushion concrete comes to the site or in the process, it is necessary to check the slump of the cushion concrete and whether it is the same as the mix proportion sheet
.
3
.
It is necessary to keep the concrete test block, the mix proportion sheet of the cushion concrete and the re examination report of the stone and sand
.
4
.
During the construction of concrete, the flatness of the concrete surface should be observed, and the construction unit should not be asked to scrape with a ruler
.
5
.
When making concrete, spare power supply, spare vibrator and other tools should be considered
.
6
.
When pouring concrete, the supervisor should generally stand by
