[0002] In construction engineering, foundation pit support and dewatering are crucial steps to ensure the safety of foundation pit construction and the stability of the surrounding environment.

[0003] Traditional foundation pit support structures typically employ on-site cast-in-place concrete or welded steel structures, resulting in long construction cycles, high costs, and difficulties in dismantling, hindering resource reuse. Furthermore, traditional dewatering systems are often independently configured, lacking effective coordination with the foundation pit support structure, making precise control of dewatering effects difficult and prone to causing excessively high or low groundwater levels, which can adversely affect surrounding buildings and underground pipelines. In addition, traditional dewatering systems have low levels of automation, requiring frequent manual monitoring and adjustments, increasing the difficulty and cost of construction management.

[0022] The present invention will be further described in detail below with reference to embodiments: Example

[0023] like Figure 1-5 As shown, this utility model provides a modular prefabricated foundation pit support and intelligent dewatering integrated device, including a modular support mechanism, which includes a support plate 11. A combination groove 12 is provided on one side of the surface of the support plate 11, and a combination edge 13 is provided on the other side of the surface of the support plate 11. An intelligent dewatering mechanism is installed on the surface of the upper modular support mechanism. The intelligent dewatering mechanism includes an installation plate 21. A microprocessor 22 is fixedly connected to the surface of the installation plate 21. An insertion pipe 23 inserted into the slope of the foundation pit is fixedly connected to one side of the installation plate 21. A water level sensor is provided on the inner wall of the insertion pipe 23.

[0024] In this embodiment, the support plates 11 of the modular support mechanism are spliced ​​together by the combination grooves 12 and the combination edges 13 to quickly assemble into a foundation pit support structure. The anchor rods 17 are inserted into the hard soil layer in the foundation pit to apply a thrust to the pressure plate 16 towards the foundation pit slope, so that the spring 15 pushes the support plate 11 to fit tightly against the surface of the foundation pit slope, providing initial support force for the foundation pit. When the pressure of the soil around the foundation pit acts on the support plate 11, the pressure is transmitted to the pressure sensor 14 through the support plate. The pressure sensor 14 converts the pressure signal into an electrical signal and transmits it to the microprocessor 22 of the intelligent dewatering mechanism. If the pressure exceeds the preset threshold, it indicates that there is a risk in the foundation pit support. The microprocessor 22 can start the water pump 25 according to the program settings to extract water from the slope and reduce the pressure on the support plate 11. Example

[0025] like Figure 1-5As shown, based on Embodiment 1, the present invention provides the following technical solution: Preferably, the modular support mechanism further includes a pressure sensor 14, one side of which is fixedly connected to one side of the support plate 11, and a spring 15 is fixedly connected to the other side of the pressure sensor 14. The pressure sensor 14 is electrically connected to the microprocessor 22, and a pressure plate 16 is fixedly connected to the side of the spring 15 away from the pressure sensor 14. An anchor rod 17 extending into the hard soil layer of the foundation pit slope is inserted into the inside of the pressure plate 16. An insertion hole 18 for an extension tube is opened on the surface of the pressure plate 16, and the insertion hole 18 for the extension tube penetrates the pressure plate 16 and the support plate 11.

[0026] In this embodiment, the dewatering pipe 24 extends into the dewatering area of ​​the foundation pit through the insertion pipe 23 and the insertion hole 18. The microprocessor 22 controls the start and stop of the water pump 25 and the pumping flow rate according to the pressure data fed back by the pressure sensor 14 and the preset program. When the pressure sensor 14 reports a large pressure, the microprocessor 22 controls the water pump 25 to increase the pumping force, and discharges the water in the foundation pit through the dewatering pipe 24 and the drainage pipe 27, thereby lowering the groundwater level, reducing the pressure of the soil on the support structure, and maintaining the stability of the foundation pit. Example

[0027] like Figure 1-5 As shown, based on Embodiment 1, this utility model provides the following technical solution: Preferably, the intelligent precipitation mechanism further includes a precipitation pipe 24 inserted into the insertion pipe 23, the bottom of the mounting plate 21 is bolted to the surface of the pressure plate 16, a water pump 25 is provided at one end of the precipitation pipe 24, an installation component 26 is provided on the surface of the water pump 25, the bottom of the installation component 26 is bolted to the surface of the pressure plate 16, a drainage pipe 27 is provided at the output end of the water pump 25, the water pump 25 is electrically connected to the microprocessor 22, and includes an insertion hole sealing component bolted to the surface of the lower modular support mechanism, the insertion hole sealing component includes a sealing plate 31, the bottom of the sealing plate 31 is bolted to the surface of the pressure plate 16, a sealing block 32 is fixedly connected to one side of the sealing plate 31, and the surface of the sealing block 32 overlaps with the inner wall of the insertion hole 18 of the insertion pipe.

[0028] In this embodiment, when the pressure drops to a safe range or the water level reaches the set requirements, the water pump 25 reduces the pumping flow or stops working. For the lower modular support mechanism that has not installed an intelligent dewatering mechanism, the sealing plate 31 is fixed to the pressure plate 16 with bolts, and the sealing block 32 is tightly inserted into the insertion hole 18 of the extension pipe to prevent soil from falling out of the insertion hole 18 and to ensure the integrity of the foundation pit support system.

[0029] The working principle of this modular prefabricated foundation pit support and intelligent dewatering integrated device will be explained in detail below.

[0030] like Figure 1-5As shown, the modular support mechanism's support plates 11 are spliced ​​together via combination grooves 12 and combination edges 13 to quickly assemble into a foundation pit support structure. Anchor bolts 17 are inserted into the hard soil layer within the foundation pit, applying a thrust to the pressure plate 16 towards the foundation pit slope. This causes the spring 15 to push the support plates 11 tightly against the surface of the foundation pit slope, providing initial support force for the foundation pit. When the pressure of the surrounding soil acts on the support plates 11, the pressure is transmitted through the support plates to the pressure sensor 14. The pressure sensor 14 converts the pressure signal into an electrical signal and transmits it to the microprocessor 22 of the intelligent dewatering mechanism. If the pressure exceeds a preset threshold, it indicates a risk to the foundation pit support. The microprocessor 22 can then start the water pump 25 according to the program settings to extract water from the slope and reduce the pressure on the support plates 11. During pumping, the dewatering pipe 24 extends through the insertion pipe 23 and the insertion hole. 18 extends into the dewatering area of ​​the foundation pit. The microprocessor 22 controls the start and stop of the water pump 25 and the pumping flow rate according to the pressure data fed back by the pressure sensor 14 and the preset program. When the pressure sensor 14 reports a large pressure, the microprocessor 22 controls the water pump 25 to increase the pumping force, and discharge the water in the foundation pit through the dewatering pipe 24 and the drainage pipe 27 to lower the groundwater level, reduce the pressure of the soil on the support structure, and maintain the stability of the foundation pit. When the pressure drops to a safe range or the water level reaches the set requirements, the water pump 25 reduces the pumping flow rate or stops working. For the lower modular support structure without the installation of the intelligent dewatering mechanism, the sealing plate 31 is fixed to the pressure plate 16 with bolts, and the sealing block 32 is tightly inserted into the insertion hole 18 of the extension pipe to prevent the soil from falling out of the insertion hole 18 of the extension pipe and to ensure the integrity of the foundation pit support system.

[0031] The present invention has been described in detail above. However, modifications or improvements can be made to it, which will be obvious to those skilled in the art. Therefore, any modifications or improvements that do not depart from the spirit of the present invention are within the protection scope of the present invention.
