The elastic piston 32 is connected with a push rod 33 arranged in the axial direction of the inscribing tube 3. The upper end of the push rod 33 penetrates the top side wall and extends to the outside of the labeling tube 3.
When the detecting instrument body detects that the underground pipeline is damaged or broken, a detecting person presses the push rod downwards, the elastic piston downwards extrudes the marking liquid, and then the marking liquid is sprayed to the damaged or broken part of the underground pipeline on the ground through the nozzle.
According to the underground pipeline detection device for building construction, when a detection worker detects a damaged part of an underground pipeline through the detection probe at the detection lower end of the detection instrument body, the push rod is pressed downwards, so that the marking liquid is sprayed from the nozzle on the marking pipe to be vertically sprayed to the ground of the damaged part, and therefore marking is performed.
The outer side of the lower end of the detection is sleeved with a protective sleeve. The inboard of protective sheath is equipped with the rubber ring, and the inboard rubber ring of protective sheath is closely laminated with the bottom outside of surveying the lower extreme. When not using, accessible protection is surveyed the lower extreme and is carried out parcel protection to the test probe outside.
As a preferred embodiment, referring to fig. 4, a fixing shaft is connected between two opposite side walls of the vertical through groove of the base. The end of the support rod 22 is formed with a collar. The fixed shaft is rotatably arranged in the lantern ring in a penetrating way.
