Description

Technical Field

[0001] The invention relates to the field of geological conditions, and in particular to a device capable of real-time monitoring of deformation of soil bodies of multiple types of foundation pits. Background Art

[0002] In the process of monitoring the deformation of foundation pit soil, most of the soil deformation is uniform, so the monitoring work is relatively simple. For areas with complex geological conditions, in the process of monitoring the deformation of foundation pit soil, because the soil deformation speeds in different areas of the foundation pit are different, long-term monitoring takes too long. Moreover, in the monitoring process, if there is a local depression on the ground, the shape of the depression will further change in an irregular manner under complex geological conditions. For large-area foundation pits, most monitoring equipment is difficult to carry out corresponding monitoring work for the above situation. Therefore, in order to quickly confirm the probability of depression caused by the geological conditions in the area corresponding to the foundation pit, it is necessary to fill the foundation pit with heavy objects to simulate the state after the foundation pit is backfilled, so as to obtain the foundation pit collapse points in advance and facilitate the corresponding pre-remediation. However, the method of filling heavy objects makes it impossible for traditional monitoring equipment to carry out corresponding monitoring work due to the loss of field of view.

[0012] The present invention provides a device capable of real-time monitoring of deformation of multiple types of foundation pit soil. When monitoring the soil of the foundation pit, the coating layer is laid flat on the soil surface of the foundation pit, and then the monitoring mechanism is placed into the foundation pit at an angle perpendicular to the coating layer according to the shape and position of the foundation pit until the foundation pit is filled with the monitoring mechanism, and then the area between the shell, the first elastic layer and the second elastic layer is filled with liquid, and the third elastic layer at the bottom of the pressing plate is pressed tightly by the first elastic layer.

The positioner 6 and the processor 7 are both electrically connected to an external power supply. When the soil of the foundation pit is monitored, the coating layer 5 is leveled. The monitoring mechanism is laid on the soil surface of the foundation pit. At this time, the position of the locator 6 on the coating layer 5 can be regarded as the initial position. Then, according to the shape and position of the foundation pit, the monitoring mechanism is placed into the foundation pit at a perpendicular angle to the coating layer 5 until the foundation pit is filled with the monitoring mechanism. Then, the area between the shell 1, the first elastic layer 2 and the second elastic layer 3 is filled with liquid, and the third elastic layer 9 at the bottom of the pressing plate 8 is pressed tightly by the first elastic layer 2. Under the action of the pressing plate 8, the liquid in the area between the shell 1, the first elastic layer 2 and the second elastic layer 3 is prevented from being pushed open. Under the pressure of the device on the foundation pit soil, the softness of the soil and the influence of geological factors, the foundation pit is The pit soil will deform downward to a certain extent, causing multiple depressions in the foundation pit soil.
