Building engineering quality detection device

The invention relates to the technical field of constructional engineering, in particular to a constructional engineering quality detection device which comprises a base, supporting frames are fixed to the two ends of the top of the base, the supporting frames are connected with fixing mechanisms, the fixing mechanisms are used for fixing foundation piles, and a moving seat is arranged between the supporting frames; the moving seat is connected with the supporting frame through a translation mechanism, the translation mechanism is used for driving the moving seat to move horizontally, the top of the moving seat is slidably connected with arc-shaped seats which are symmetrically distributed, the arc-shaped seats are connected with the moving seat through a driving mechanism, the driving mechanism is used for driving the arc-shaped seats to move relatively, and detection mechanisms are arranged on the inner sides of the arc-shaped seats. The detection mechanism is used for detecting the diameter of the foundati
