Description

Excavation construction monitoring device and ground improved structure construction quality control method using the same The present invention relates to an excavation construction monitoring device and a method for managing the construction quality of a ground improvement body using the same. More specifically, it enables the construction quality of a ground improvement body to be managed to a certain level or higher during the process of constructing a ground improvement body to strengthen the bearing capacity of the ground. In particular, the present invention relates to an excavation construction monitoring device and a method for managing the construction quality of a ground improvement using the same, which can significantly improve the construction quality of a ground improvement by accurately measuring the excavation depth of a ground improvement using a GNSS (Global Navigation Satellite System) and managing various data in conjunction with the excavation depth of the ground improvement. When constructing a structure on soft ground, safety issues may arise due to ground subsidence; to prevent this, a ground improvement process is undertaken before construction begins. Soft ground improvement is the process of improving the ground primarily for purposes such as revetments, breakwaters, river embankments, roads, and land development, as well as for the construction of architectural structures like buildings and bridges. It involves injecting a soil solidification agent, such as a cement-based one, into the soft ground, mixing it, and then curing the resulting improved ground structure to strengthen the bearing capacity of the soft ground. To examine the soft ground improvement process in detail, the ground is excavated to a certain depth and shape using an excavator combined with an auger and a rod, and a solidifying agent is injected into the ground and cured to construct a ground improvement body, thereby strengthening the bearing capacity of the soft ground. At this time, a device for construction quality control of the ground improvement body was mounted on the excavator, and mainly the verticality of the rod and the bottom load pressure value were displayed. However, these soft ground improvement technologies and construction quality control devices have the following problems. First, in the case of ground improvement bodies for ground reinforcement, it is of paramount importance whether the body has been constructed to the desired depth; however, existing construction quality control systems made it impossible to measure and verify these aspects. Second, in order to ensure the reliability of the construction of the ground improvement, data must be secured regarding whether the ground improvement was constructed to the correct depth during the construction process; however, as explained earlier, since measuring the depth is impossible, it is difficult to ensure the reliability of quality control. Third, in the case of simple ground drilling operations, the drilled depth can be measured using a laser sensor after drilling; however, during the process of constructing ground improvement structures for ground reinforcement, a soil solidifying agent is injected simultaneously with drilling to cure (solidify), so the error in the data measuring the distance to the bottom using a laser sensor is inevitably large. Fourth, construction equipment such as excavators is often rented from the owner for a certain period or a certain number of times. In the case of a method that indirectly measures the excavation depth by installing an angle-measuring sensor on the excavator's arm and measuring the arm's rotation angle, there is a problem in that a separate skilled technician must be deployed in the process of removing the angle-measuring sensor installed on the excavator when the rental ends and the excavator is returned, after the construction equipment is rented and the angle-measuring sensor is installed on the excavator's arm. Consequently, existing methods face many limitations in measuring excavation depth during the construction of ground improvement structures, which leads to the problem that the construction quality of the said ground improvement structure cannot be guaranteed. The following prior art document, Korean Patent Publication No. 10-2020-0087995, 'Pile installation method for soft ground and photovoltaic structure using the same' (hereinafter referred to as 'prior art'), describes a method for stably and firmly installing a photovoltaic structure on soft ground or a slope, and states that the standard length of the pile is determined by considering the depth and location from the ground to the bedrock layer. However, since this merely involves cutting the pile length to match the depth specified in the design and does not measure the excavation depth during the actual excavation process or the depth of the constructed pile, it cannot be said to secure accurate construction data or manage
