In recent years, urban railways, which are mainly installed in the basement, are playing an increasingly important role in urban traffic and transportation. These urban railways have the characteristics that the railway is installed and operated by passing through the tunnel 1 through the characteristics installed underground. On the other hand, in addition to the urban railway, high-speed railway networks or high-speed roads are also increasingly applied through tunnel structures due to reasons such as straightening of routes. On the other hand, in the case of the city, the construction of the underground passage structure is gradually increasing due to the problem of securing the facility space.

In this way, the structural stability of the tunnel installed in the underground includes various factors such as the composition of the ground on which the tunnel is installed and the surrounding geological structure as well as the existence of groundwater flowing in the surrounding water- .

However, due to urban expansion and expansion of facilities development, it causes change of ground structure near the existing facilities, and the risk of collapse of the tunnel is increased due to the change and weakening of the nearby ground due to the construction of buildings in the city center. In addition, due to the inflow of foreign matter from groundwater due to underground construction and the change of groundwater flow, the corrosion of tunnel facilities and the sudden deterioration of facilities are caused. However, due to the lack of a quantitative and periodic observation system of tunnel facilities, it is not possible to detect the risk factors by monitoring the changes of the ground and groundwater environment in real time. Therefore, it is impossible to prevent the accidents beforehand, , Leading to direct damage to the people.

Particularly, when a cavity is formed around a tunnel facility, and at the same time, the flow of groundwater passes through the co-generated portion, the cavity rapidly expands and a sink hole is generated. There are cases where this difficult situation occurs.

As a technique relating to measurement of the underground structure such as a tunnel facility, it is possible to move the upper part of the water surface of the river to the river bed ground survey system using GPS and GPR (Patent Document 10-2004-0092508) A water moving means; An underground survey radar (GPR) device mounted on the water moving means and including a control unit and a transmit / receive radar; A GPS device mounted on an upper portion of the water moving means to calculate current position information; And an information processing apparatus connected to the ground surveying radar apparatus and the GPS apparatus so as to exchange data with each other.

However, the existing invention has a problem in that it can not be applied to the monitoring of the ground around the tunnel facilities, because it relates to a bed ground survey system using one GPR (ground survey radar) equipped with water moving means.

Also, as mentioned above, there is a problem that it is impossible to monitor the characteristics of the groundwater in conjunction with the state of the ground as well as the state of the ground.
