The traditional pre-buried hole positioning method relies on manual measurement and positioning, which is not only inefficient, but also prone to deviation, affecting the installation accuracy and stability of the subsequent structure. Therefore, there is an urgent need for a mould frame structure that can quickly and accurately position the pre-buried hole of the cushion stone to improve construction quality and efficiency.
