Accurate drilling device for leakage of underground structure outer wall

Abstract

The invention discloses an accurate drilling device for leakage of an underground structure outer wall. The accurate drilling device comprises a bottom plate, wherein an ultrasonic flaw detector is installed on one side of the top of the bottom plate; a control panel is installed at the center of the outer wall of the ultrasonic flaw detector; a display screen is installed at the center of the topof the ultrasonic flaw detector; an ultrasonic probe is fixed to one side of the ultrasonic flaw detector through a signal line; a drilling assembly is installed on the other side of the top of the bottom plate; and the control panel is electrically connected with the ultrasonic flaw detector, the display screen and the drilling assembly. According to the accurate drilling device, the structure is novel, the conception is ingenious, construction personnel can conveniently and accurately know leakage point information of the underground structure outer wall, the drilling assembly can accurately drill leakage points of the underground structure outer wall, and the later leakage repairing effect can be conveniently improved.

Description

technical field [0001] The invention relates to the technical field of exterior wall construction, in particular to a precision drilling device for leakage of an exterior wall of an underground structure. Background technique [0002] At present, after the construction of the exterior wall of the underground structure is completed, the concrete will generally shrink, which will cause the exterior wall to separate from the waterproof layer and form a gap; in addition, when the surface of the exterior wall is uneven, there will be a certain gap between the waterproof layer and the exterior wall During the construction process, the waterproof layer will be damaged, and groundwater will seep along the waterproof layer. The gap between the exterior wall and the waterproof layer and the enclosure structure is filled with water. When there are through cracks on the surface of the exterior wall, the exterior wall will leak, which will affect the appearance quality of the building, t...
