Skirt pile sleeve diameter measuring method

The invention discloses a diameter measuring method for a skirt pile sleeve. The diameter measuring method comprises the following steps that S1, a flat cylinder matched with the inner diameter of the skirt pile sleeve is manufactured; s2, battens are additionally arranged in the edges of the two sides of the oblate barrel, and the battens on the two sides are laid and connected through a three-ply board and used for stabilizing the tool; s3, handles are installed on the battens; s4, a front person and a rear person hold a handle to lift the tool to walk from the bottom end of the flat skirt pile sleeve to the top end of the skirt pile sleeve in parallel; and S5, if the tool can be stably lifted out, a certain gap is formed between the outer diameter of the tool and an inner accessory of the skirt pile sleeve, and the inner diameter ovality of the whole skirt pile sleeve meets the construction requirement. According to the invention, the inner diameter of the skirt pile sleeve can be visually measured, the mu
