Claim 0:
1. A wireless detection device for quickly positioning a throw-fill stone falling depth and long-term settlement in blasting silt-squeezing construction, comprising: a gravity ball and a signal receiving, processing and controlling system, wherein the gravity ball comprises a housing supported by corrosion-resistant steel, the housing is internally provided with test mechanisms, signal collecting and transmitting apparatuses and batteries, the test mechanisms send signals obtained by testing outwards through the signal collecting and transmitting apparatuses, the signal receiving, processing and controlling system is configured to receive a wireless signal transmitted by the gravity ball, and the signal receiving and controlling system is capable of controlling a monitoring device in the gravity ball;
wherein each of the test mechanisms comprises a vacuum negative pressure monitoring system, a pore pressure sensor and a gas pressure sensor;
each vacuum negative pressure monitoring system comprises a vacuum negative pressure detection apparatus, a vacuum negative pressure chamber, a vacuum negative pressure gas discharging apparatus, a vacuum negative pressure gas hole and fluid channel, and a vacuum negative pressure gas discharging hole, each vacuum negative pressure detection system is configured to measure a hydrostatic pressure, and gas in each vacuum negative pressure chamber is discharged through a corresponding vacuum negative pressure gas discharging apparatus;
each pore pressure sensor is configured to measure a pore pressure in silt to determine a dissipation degree of an excess pore pressure in a blasting operation; and
each gas pressure sensor is configured to measure an altitude when the gravity ball falls into the silt.
