Static sounding trepanning device

A static sounding tapping device comprises a tapper and a fixator, a connector is arranged in the center of the upper end of the tapper, a water inlet hole is formed in the middle of the connector, and an outward fixing plate is arranged on the edge of the fixator; wherein the outer diameter of the tapper is larger than the blade diameter of the static sounding geomorphology, and the inner diameter of the fixer is slightly larger than the outer diameter of the tapper. The device provided by the utility model solves the problem that the static sounding test can not be carried out on the hardened ground site, greatly improves the site adaptability of the static sounding survey means, and can effectively save the survey cost, and the fixer can effectively solve the problem that the tapper slips on the hardened ground, thereby avoiding the injury to the legs and feet of an operator due to the slipping. The device is wide in application range, can also be used in other fields, and is low in cost, low-carbon, envir
