TECHNICAL FIELD

[0001] The present application relates to a kind of drilling protection auxiliary devices and construction method. BACKGROUND

[0002] The anti-collision guard includes a column and a beam. The column and the beam are provided with prefabricated holes. After the column is installed by a pile driver on site, the prefabricated holes on the beam are aligned with the prefabricated holes on the column, and then installed by means of bolts.
