Preferably, described low bottom-disc centre bore aperture diameter is 14mm.
Preferably, the thickness of described low bottom-disc is 2mm, and diameter is 200mm, the thickness of upper rminal disc is 2mm, and diameter is 100mm, and the diameter of probe is 12mm, length is 550mm, and the DN15 coating steel pipe of steel pipe to be length be 250mm, the portion size that probe is stretched in steel pipe is less than or equal to 250mm.
Preferably, the upper surface of described rubber stopper is fixedly connected with connection cord, and the other end of connection cord is connected with fixed end.
Preferably, described upper rminal disc top " bikini " hoist cable, is evenly distributed on the outward flange of upper rminal disc.Three hoist cables ensure stability during traction, improve the stability of measuring appliance.
Preferably, the diameter of " mushroom head " of described probe tip is greater than the internal diameter of rubber ring and the aperture of low bottom-disc centre bore.Skid off from steel pipe bottom when preventing probe from gliding.
Preferably, the dead in line of described steel pipe, probe, upper rminal disc and low bottom-disc.
The beneficial effect that the utility model brings is: adopt sediment thickness measuring appliance at the bottom of the tower pile foundation hole with probe, because low bottom-disc contact area is large, pressure is relatively little to sediment, probe is because of little in tip-like area, then pressure can pass greatly the principle that sediment go directly at the bottom of hole, sediment thickness can be measured accurately, increase work efficiency, ensure construction quality, significantly improve the degree of accuracy that sediment at the bottom of pile foundation hole is measured, for construction quality accident provides definite foundation, ensure that the construction quality of pile foundation, also greatly increase work efficiency.
