Water seepage detection device for bridge construction

The invention relates to the technical field of detection devices, and discloses a bridge construction water seepage detection device which comprises a protective shell, a servo motor is arranged at the top end of the interior of the protective shell, a lead screw is fixed to the output end of the servo motor, and the lead screw is rotationally connected with an upper partition plate of the protective shell through a bearing; by means of the lead screw and the sleeve, when the drilling barrel is used, the process does not need to be controlled manually, the coring precision is guaranteed, meanwhile, by means of the mode that drilling is conducted firstly for coring and then water storage detection is conducted, the coring efficiency is improved, and the coring efficiency is improved. The problems that in the detection process of an existing bridge construction water seepage detection device, due to heat in the coring process, a water seepage layer is partially evaporated, imaging is not obvious, and the detec
