Construction process and method for pore-forming cast-in-place pile of rotary drilling rig

[0028] Embodiment one

[0029] refer to figure 1 , a construction method of a rotary drilling rig to form a bored pile, comprising the following process steps:

[0030] S1: Draw drawings and prepare equipment;

[0031] S2: Clean up the site, draw a line for positioning;

[0032] S3: positioning drilling;

[0033] S4: drilling detection;

[0034] S5: Bury the casing frame;

[0035] S6: install the casing;

[0036] S7: mix and adjust the concrete for standby;

[0037] S8: Pouring concrete.

[0038] In this embodiment, scale drawings are installed in S1, and drilling equipment is prepared and checked.

[0039] In this embodiment, in S2, the site is cleaned and cleared according to the drawings, and the site is drawn and positioned.

[0040] In this embodiment, a rotary drilling rig is used to dig holes in S3. Firstly, holes for placing the casing are dug out, and then spread outwards to dig out holes for placing the casing frame.

[0041] In this embodiment, in S4, a press
