Description

Technical Field

[0001] The present application relates to the technical field of foundation pit slope displacement monitoring, and in particular to a foundation pit slope displacement monitoring device. Background Art

[0002] Pit slope displacement refers to the horizontal or vertical movement of the slope soil during the excavation process, caused by its own weight and external forces (such as construction loads and groundwater pressure). If this displacement exceeds a certain limit, it will affect the stability of the pit and even lead to engineering accidents. For example, excessive slope displacement may cause pit collapse, posing a safety threat to construction workers and the surrounding environment. It may also affect the stability of the pit support structure, causing it to fail, thus affecting the smooth progress of the entire project. In addition, due to the limited monitoring location of slope displacement, inaccurate monitoring results, and low monitoring efficiency, it will increase project costs and cause economic losses.

[0003] At present, in order to improve the construction efficiency of foundation pits, it is necessary to monitor the displacement of foundation pit slopes in real time. Monitoring equipment mainly includes inclinometers, total stations, levels, etc. to judge the displacement and settlement of foundation pit slopes. Although this type of equipment can accurately monitor the displacement of the slope, it requires operators to operate the instruments, which increases the operating cost. At the same time, it cannot measure the displacement in real time. There is a possibility that the slope displacement will occur during the unmeasured time period. When there are measurement errors in multiple scattered measurements, the exact displacement cannot be accurately determined. In addition, due to the large slope area of ​​the slope, the currently used measurement instruments cannot fully monitor the displacement of the entire slope surface, and there are safety hazards of displacement in the unmonitored areas. Summary of the Invention

[0004] In response to the above-mentioned problems, the present application aims to provide a foundation pit slope displacement monitoring device, which solves the shortcomings of the current monitoring instrument that cannot be used for real-time detection and cannot fully monitor the entire slope surface. At the same time, it solves the problem of increased operating costs caused by multiple manual operations of the monitoring instrument and insufficient monitoring accuracy due to monitoring errors.

[0005] In order to achieve the above-mentioned purpose, the technical solution adopted in this application is as follows: a foundation pit slope displacement monitoring device, characterized in that: the monitoring device includes a fixed component fixed to the top side of the foundation pit, and a monitoring component corresponding to the slope surface and against the slope surface is connected to the fixed component.

[0006] Preferably, the fixing member comprises a fixing plate placed on the ground at the top side of the foundation pit, and fastening nails penetrating into the ground are evenly distributed on the fixing plate.

[0007] Preferably, the monitoring component includes a monitoring rod that can be hinged and locked at the end of the fixed plate. The monitoring rod is parallel to the slope surface with a gap, and a displacement monitor that is against the slope surface is arranged at a gap inside the monitoring rod.

[0008] Preferably, a plurality of displacement plates are laid on the slope surface, and a guide rod passing through the monitoring rod is provided at the side of each displacement plate.

[0009] The beneficial effects of this application are: the monitoring device, through the monitoring component, achieves real-time monitoring of the slope surface on the basis of complete monitoring of the slope surface, resolving the shortcomings of current monitoring instruments, such as the inability to detect in real time and the inability to fully monitor the entire slope surface. It also addresses the current problems of increased operating costs caused by multiple manual operations of the monitoring instrument and insufficient monitoring accuracy due to monitoring errors. The displacement monitoring device can also promptly detect abnormal slope displacement and take appropriate measures to address it, thereby ensuring the safety and quality of the foundation pit project.

[0016] In order to enable ordinary technicians in this field to better understand the technical solution of the present application, the technical solution of the present application is further described below in conjunction with the accompanying drawings and embodiments.

[0017] Refer to the attached Figures 1 to 5A foundation pit slope displacement monitoring device is shown, which includes a fixed component fixed to the top side of the foundation pit 1, and a monitoring component corresponding to the slope surface 1a and counteracting the slope surface is connected to the fixed component. The entire device is fixed to the top side of the foundation pit by the fixed component, and after fixing, the monitoring component is made to correspond to the slope surface. The monitoring component preferably covers the entire slope surface and, by counteracting the slope surface, performs real-time detection of the slope surface displacement. Thus, on the basis of ensuring complete monitoring of the slope surface, real-time monitoring of the slope surface is achieved, solving the shortcomings of the current use of monitoring instruments that cannot be detected in real time and cannot fully monitor the entire slope surface. At the same time, it solves the problem of increased operating costs caused by multiple manual operations of the monitoring instrument and insufficient monitoring accuracy due to monitoring errors. Furthermore, through this displacement monitoring device, abnormal slope displacement can be discovered in a timely manner and corresponding measures can be taken to deal with it, thereby ensuring the safety and quality of the foundation pit project.

[0018] Specifically, such as Figure 1-3 As shown, the fixing member includes a fixing plate 2 placed on the ground at the top of the foundation pit 1. Fastening nails 3 are evenly distributed on the fixing plate 2 and penetrate the ground surface. When monitoring is required, the fixing plate 2 is placed on the bottom surface of the top of the foundation pit, and the fastening nails 3 are penetrated from the fixing plate 2 to the ground surface, thereby achieving rapid installation of the monitoring device.

[0019] On the basis of the above-mentioned quick installation of the fixing plate 2, as Figure 1-3 As shown, the monitoring member includes a monitoring rod 4 that can be hinged and locked at the end of the fixed plate 2. Preferably, a hinge screw 8 is provided at its hinge, which is used to adjust the monitoring rod 4 to be parallel to the slope surface, and then the monitoring rod 4 is locked by the hinge screw. The monitoring rod 4 is parallel to the slope surface and a gap is left, as shown in FIG. Figure 2-3 As shown, a displacement monitor 5 is provided inside the monitoring rod 4 at intervals to counteract the slope 1a. When there is displacement at a certain position on the slope, the geological action of the slope acts on the displacement monitor 5, and the displacement monitor 5 can accurately determine the displacement at the current position and provide real-time feedback through the transmission line, thereby obtaining the displacement of the current position (each displacement monitor 5 can be numbered to correspond to the elevation of the slope). The staff determines whether to take appropriate treatment measures based on the size of the displacement. If the displacement is small, it is possible to observe in real time whether the displacement is still changing. This effectively solves the difficulty of manual measurement using a measuring instrument and the error problem of frequent measurement.

[0020] Since the monitoring area of ​​the monitoring head of the displacement monitor 5 is limited, in order to conduct a complete monitoring of the entire slope, Figure 4-5As shown, a plurality of displacement plates 6 are laid on the slope 1a, and the slope can be covered by a plurality of displacement plates 6, and a guide rod 7 is provided on the side of each displacement plate 6 and is passed through the monitoring rod 4. Figure 4 As shown, each displacement plate 6 corresponds to a displacement monitor 5, that is, a single displacement monitor 5 can monitor the displacement of the slope area covered by the single displacement plate 6. When the slope moves, the displacement plate 6 is driven to move, and the displacement plate 6 acts on the displacement monitor 5, as shown in FIG. Figure 4 As shown, continuous monitoring points are formed on the slope surface, allowing for complete and effective monitoring of the slope, thereby enabling complete monitoring of the entire slope surface through multiple displacement plates 6. Since the slope has a certain horizontal width, multiple sets of displacement monitoring devices can be installed according to the width to achieve complete monitoring of the entire slope surface.

[0021] The principle of this application is: when monitoring the displacement of the slope, the fixed plate 2 is placed on the bottom surface of the top side of the foundation pit, and a distance is kept between the monitoring rod 4 and the slope surface. At the same time, each displacement plate 6 is in flat contact with the slope surface, and the displacement monitor 5 is in contact with the surface of the displacement plate 6. Then, the rotation state of the monitoring rod 4 is locked by the articulated screw, and then the real-time monitoring state is entered.

[0022] When there is displacement on the slope, the geology of the displacement drives the corresponding displacement plate 6, which drives the displacement monitor 5 through the guide rod 7. Then, the displacement in the displacement plate 6 can be obtained through the transmission line of the displacement monitor 5, and the accurate displacement amount can be obtained and fed back to the ground. According to the size of the displacement amount, it is determined whether corresponding measures should be taken to deal with it, thereby ensuring the safety and quality of the foundation pit project.

[0023] The above shows and describes the basic principles, main features and advantages of this application. Without departing from the spirit and scope of this application, this application will also have various changes and improvements, which fall within the scope of this application.
