Early warning device for concrete overfilling of cast-in-place pile and use method
The invention discloses an early warning device for concrete overfilling of a cast-in-place pile. The early warning device includes a fixed rod piece and an early warning rod piece, the fixed rod piece includes a hanging piece, a connecting rod and a limiting sleeve, the hanging piece is detachably fixed to the upper part of a steel pile casing, the connecting rod is fixed to the hanging piece anda connecting end extends out, the limiting sleeve is fixed to the connecting end, and the limiting sleeve is of a hollow structure; and the early warning rod piece includes an early warning rod and upper and lower supporting plates, the early warning rod is suitable for penetrating through the limiting sleeve, the upper and lower supporting plates include an upper supporting plate and a lower supporting plate, the upper supporting plate is fixed to the top of the early warning rod and is suitable for freely falling at the top of the limiting sleeve, and the lower supporting plate is suitablefloating in concrete and the buoyancy is sufficient to support the early warning rod piece. The early warning device can more quickly and intuitively reflect the overfilling height in the concrete pouring process than a traditional rope measuring method at present, rope measurement does not need to be repeatedly used for measurement and the concrete pouring amount does not need to be increased toensure the quality of the cast-in-place pile, and the concrete amount is saved.
本发明公开了一种灌注桩混凝土超灌量预警装置，包括固定杆件和预警杆件，所述固定杆件包括挂件、连接杆和限位套管，所述挂件可拆卸地固定于钢护筒上部，所述连接杆与挂件固定且伸出一连接端，所述限位套管与连接端固定，所述限位套管为中空结构；所述预警杆件包括预警杆和上下托板，所述预警杆适于穿过限位套管，所述上下托板包括上托板和下托板，所述上托板固定于预警杆顶部且适于自由落在限位套管顶部，所述下托板适于在混凝土中浮起且浮力足以撑起预警杆件。本发明装置较目前传统所用的绳测法更能快速、直观反应混凝土浇筑过程中达到超灌高度，不用反复使用绳测进行丈量及为保证灌注桩质量，增加混凝土浇灌量，节约混凝土用量。
