The invention discloses a settlement cup monitoring system for monitoring subgrade settlement. The settlement cup monitoring system comprises a measuring settlement cup in the subgrade filling, a base, a reference settlement cup disposed on the base, and a connected water pipe. Each settlement cup is composed of a water tank, a water pressure gauge, a water inlet and an exhaust port. The water inlet is located at the bottom of the water tank. The exhaust port is located at the top of the water tank. The exhaust port is provided with a sealing screw and a first sealing ring set between the exhaust port and the sealing screw. The water pressure gauge is fixed on the inner sidewall of the water tank and is connected with a power source through a lead, and a second sealing ring is arranged around the gap between the lead and the water tank; and the water inlet of the measuring settlement cup is communicated with the water inlet of the reference settlement cup through the water pipe. The system measures the elevation of the settlement cup, and the pressure value of the water pressure gauge, so that the settlement can be calculated. Therefore the settlement cup monitoring system is easy to read and high in measurement precision, and is not affected by the construction of the filling.
Description
technical field [0001] The invention relates to the technical field of subgrade settlement monitoring, in particular to a settling cup monitoring system and a measuring method thereof. Background technique [0002] Existing settlement measurement methods generally include leveling, which is to obtain the settlement amount by measuring the elevation of the settlement plate or settlement mark buried in the roadbed fill with leveling equipment. The main problems of this method are: first, the measurement error is relatively large due to factors such as instrument error, measurement operation error, weather change, and construction environment; Larger, even lead to interruption of measurement. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of the above-mentioned prior art, and provide a settling cup monitoring system and its measuring method. [0004] The present invention is achieved through the following technical pr...
