Sounding pipe protection device

The utility model provides a sounding pipe protection device, include: sounding pipe, the even establishes inside the bored concrete pile for detect through the sound wave the bored concrete pile, theprotection tube is worn to locate inside the sounding pipe, be used for preventing sounding pipe destroyed because of the extrusion, protective plug establishes in the protection tube top port, be used for preventing get into debris in the protection tube. The beneficial effects of the utility model reside in that, through set up protection tube and protective plug in sounding pipe, avoided sounding pipe damaged by external force extrusion deformation, perhaps block up and unable the use to this device simple structure, convenient to use is swift. 本实用新型提出了种声测管保护装置，包括：声测管，均匀的设在灌注桩内部，用于通过声波检测所述灌注桩；保护管，穿设于所述声测管内部，用于防止所述声测管因挤压遭破坏；保护塞，设在所述保护管顶部端口内，用于防止所述保护管内进入杂物。本实用新型的有益效果在于，通过在声测管内设置保护管以及保护塞，避免了声测管受外力挤压变形损坏，或者堵塞而无法使用，并且本装置结构简单，使用方便快捷。
