Description

Technical Field

[0001] The utility model belongs to the technical field of foundation pit dewatering monitoring, in particular to a device for monitoring foundation pit dewatering. Background Art

[0002] During civil engineering construction, a foundation pit is typically excavated at the designed foundation location according to the base elevation and dimensions. To prevent groundwater from impacting the excavation and subsequent construction, drainage and dewatering are required both before and after excavation. Currently, dewatering of foundation pits is typically done using the wellpoint method, which involves setting up dewatering wells around the pit and pumping out water to lower the water level within the pit.

[0003] However, in the dewatering of large foundation pits, multiple dewatering wells are usually required. In order to avoid the water level in the dewatering wells being too low or too high, the water level in each dewatering well needs to be monitored. Currently, manual measurement is usually used, which requires a lot of manpower and is difficult to accurately record water level changes and track and analyze.

[0004] In view of this, a device for monitoring foundation pit dewatering is proposed. Utility Model Content

[0022] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0023] Reference Figure 1-3 A device for monitoring foundation pit dewatering includes a monitor 1 installed above the dewatering well. A microwave ranging sensor 12 facing directly downward is provided at the bottom of the monitor 1. The monitor 1 is vertically installed above the dewatering well. The microwave ranging sensor 12 on the monitor 1 can measure the distance between the water surface and the microwave ranging sensor 12 in real time, so that the current water level of the dewatering well can be known in real time, and the water level changes can be accurately recorded and tracked for analysis, which can greatly reduce the manpower consumed in manual monitoring.

[0024] Furthermore, one side of the monitor 1 is provided with a clamping mechanism for fixing it to the top of the precipitation well, wherein the clamping mechanism includes a clamping arm 10, a threaded rod 7 and a pressure plate 8. The clamping arm 10 is installed at one end of the monitor 1 and has an inverted "U"-shaped clamping cavity. The threaded rod 7 is threadedly installed on the side wall of the clamping arm 10, and one end of the threaded rod 7 extends into the clamping cavity and is fixedly connected to the pressure plate 8. When installing the monitor 1, the clamping cavity of the clamping arm 10 can be clamped on the edge of the wellhead of the precipitation well, and then the feed distance of the pressure plate 8 is adjusted according to the thickness of the wellhead until the pressure plate 8 can be pressed tightly on the wellhead, so that the monitor 1 can be fixed as a whole on one side of the wellhead of the precipitation well. The overall structure is simple, and the monitor can be disassembled as a whole and installed on the precipitation well (not shown in the figure) through the clamping mechanism, which facilitates the installation and disassembly operation of the monitor 1.

[0025] In addition, the overall size is smaller than that of traditional monitoring equipment, which facilitates the overall carrying operation and will not interfere with the normal pumping operation of the pumping equipment.

[0026] Furthermore, anti-slip pads 9 are bonded to the opposite end faces of the clamping arm 10 and the pressure plate 8, and the outer surfaces of the anti-slip pads 9 are protruding with anti-slip grooves. Through the cooperation of the anti-slip pads 9 and the anti-slip grooves, the friction between the clamping arm 10, the pressure plate 8 and the precipitation well can be increased, thereby ensuring the stability of the monitor 1 after installation.

[0027] The anti-slip pad 9 is made of silicone or rubber, but is not limited here.

[0028] Furthermore, the other end of the threaded rod 7 is fixedly connected to a plum blossom handle 6, which allows workers to adjust the feed depth of the threaded rod 7 without tools, thereby facilitating installation and removal of the monitor.

[0029] Furthermore, the inner end surface of the top of the clamping arm 10 has a horizontal section, and the horizontal section contacts the upper end surface of the dewatering well to ensure the horizontality after subsequent clamping by the clamping mechanism.

[0030] Furthermore, a bubble level 3 is embedded in the upper surface of the monitor 1 , and the bubble level 3 can be used to check whether the current monitor 1 is installed horizontally, until the monitor 1 is adjusted to a horizontal state, so as to ensure the monitoring accuracy of the monitor 1 .

[0031] Furthermore, the outer cover of the microwave ranging sensor 12 is provided with a protective cover 5 with an opening at the lower end. The protective cover 5 can provide a certain dustproof and waterproof effect for the microwave ranging sensor 12.

[0032] Furthermore, the monitor 1 has a accommodating cavity 11 inside, and a battery 14 and a PCBA mainboard 13 are arranged inside the accommodating cavity 11. A control button is also provided on the side of the monitor 1. The monitor 1 is also provided with a wiring connector 2 electrically connected to the PCBA mainboard 13, and can be electrically connected to an external power supply or an external main control terminal (not shown in the figure) through the wiring connector 2.

[0033] It should be mentioned that the monitor 1 can be used in conjunction with the pumping equipment through the main control terminal, and the opening and closing operations of the pumping equipment can be adjusted accordingly according to the changes in water level. The overall operation is more intelligent, and how to achieve it will not be elaborated in detail here.

[0034] Furthermore, a solar panel 4 electrically connected to the battery 14 is embedded on the top of the monitor 1. The solar panel 4 can convert solar energy into electrical energy for use by the monitor 1. A micro inverter and a voltage relay (not shown in the figure) are also provided between the solar panel 4 and the battery 14.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
