Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a foundation pit deformation control device. Background Technology

[0002] In the field of construction engineering, the stability of the foundation pit is crucial to the safety and quality of the entire project. As the scale and depth of foundation pit projects continue to increase, the requirements for foundation pit deformation control are also becoming more stringent. Existing methods for foundation pit deformation control mainly include soil nailing walls, internal bracing systems, and pile support combined with prestressed anchor cable systems. However, these traditional methods have many problems in practical applications:

[0003] Soil nailing requires precise control of the driving angle and depth of the soil nails. Under complex geological conditions, the anchoring effect of the soil nails is difficult to guarantee, making construction quite challenging. Internal support systems require the construction of support structures inside the foundation pit. The installation and dismantling process is complex, consuming a lot of manpower and resources. Furthermore, untimely or improper dismantling may affect the subsequent construction progress. If the anchoring depth of the pile support combined with the prestressed anchor cable system is insufficient, it may lead to excessive pile displacement, thereby causing construction safety issues.

[0004] Moreover, the deformation of the foundation pit is dynamic during construction, and traditional methods cannot monitor the deformation in real time and adjust the support measures accordingly. Once the deformation of the foundation pit exceeds the safe range, traditional support measures are often unable to adjust quickly and effectively, leading to uncontrolled deformation and safety accidents.

[0005] Therefore, there is an urgent need for a foundation pit deformation control device to solve the above-mentioned technical problems. Utility Model Content

[0033] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0035] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0037] In the field of construction engineering, the stability of the foundation pit is crucial to the safety and quality of the entire project. As the scale and depth of foundation pit projects continue to increase, the requirements for foundation pit deformation control are also becoming more stringent. Existing methods for foundation pit deformation control mainly include soil nailing walls, internal bracing systems, and pile support combined with prestressed anchor cable systems. However, these traditional methods have many problems in practical applications:

[0038] Soil nailing requires precise control of the driving angle and depth of the soil nails. Under complex geological conditions, the anchoring effect of the soil nails is difficult to guarantee, making construction quite challenging. Internal support systems require the construction of support structures inside the foundation pit. The installation and dismantling process is complex, consuming a lot of manpower and resources. Furthermore, untimely or improper dismantling may affect the subsequent construction progress. If the anchoring depth of the pile support combined with the prestressed anchor cable system is insufficient, it may lead to excessive pile displacement, thereby causing construction safety issues.

[0039] Moreover, the deformation of the foundation pit is dynamic during construction, and traditional methods cannot monitor the deformation in real time and adjust the support measures accordingly. Once the deformation of the foundation pit exceeds the safe range, traditional support measures are often unable to adjust quickly and effectively, leading to uncontrolled deformation and safety accidents.

[0040] Therefore, there is an urgent need for a foundation pit deformation control device to solve the above-mentioned technical problems.

[0041] like Figures 1-3 As shown, this embodiment provides a foundation pit deformation control device, which includes a monitoring mechanism 1, a support mechanism 2, and a control mechanism 3. The monitoring mechanism 1 is used to monitor the deformation of the foundation pit 100. The support mechanism 2 includes a support driver 21 and a support assembly 22. The support driver 21 can drive the support assembly 22 to move and push against the inner wall of the foundation pit 100. The control mechanism 3 is communicatively connected to the monitoring mechanism 1 and can control whether the liquid in the depressurization well 200 in the foundation pit 100 flows through the support driver 21. When the deformation monitored by the monitoring mechanism 1 exceeds a preset standard, the control mechanism 3 can control the liquid to flow through the support driver 21, so that the support driver 21 moves to drive the support assembly 22 to push against the inner wall of the foundation pit 100.

[0042] In this embodiment, the monitoring mechanism 1 can accurately acquire the deformation data of the foundation pit 100. Once the deformation exceeds the preset standard, the control mechanism 3 controls the flow of liquid in the depressurization well 200 to the support actuator 21 to save construction costs. The support actuator 21 drives the support assembly 22 to push against the inner wall of the foundation pit 100, thereby adjusting the support force in a timely manner to control the deformation of the foundation pit 100 and ensuring the safety and efficiency of the construction operation. This setup improves the reliability, safety, and construction efficiency of the foundation pit 100 deformation control, reduces construction safety risks, ensures the smooth progress of the foundation pit 100 project, and solves the problems of high construction difficulty, poor results, and lack of real-time monitoring and automatic adjustment functions in traditional methods. Through the above setup, the foundation pit deformation control device of this embodiment can achieve real-time monitoring and automatic adjustment of the deformation of the foundation pit 100, making it safer, more efficient, and with lower construction costs.

[0043] The specific structure of the foundation pit deformation control device is described below:

[0044] Specifically, such as Figures 1-3 As shown, the support actuator 21 includes a rotating member 211 and multiple blades 212. The multiple blades 212 are spaced apart on the rotating member 211. By pushing the blades 212 with liquid, the rotating member 211 can be driven to rotate around its own axis. The rotating member 211 is configured to be connected to the support assembly 22, so that the support actuator 21 can use liquid power to make the rotating member 211 rotate, thereby providing power to the support assembly 22, thus making full use of natural energy and reducing construction costs.

[0045] More specifically, in this embodiment, the rotating component 211 is a rotating shaft, and multiple blades 212 are spaced apart around the outer peripheral wall of the rotating shaft. This not only has a simple structure and is easy to manufacture, but also can efficiently convert hydrodynamics into mechanical rotation. In other embodiments, the rotating component 211 is a rotating rod, which is easy to manufacture and can be sourced locally. Therefore, the specific structure of the rotating component 211 is not limited here.

[0046] Specifically, the support assembly 22 includes a base 221, a transmission component 222, an adjusting component 223, a first support component 224, and a second support component 225. The transmission component 222 is rotatably connected to the base 221 and to the rotating component 211. The adjusting component 223 is rotatably connected to the transmission component 222. When the transmission component 222 rotates, it drives the adjusting component 223 to move along the extension direction of the transmission component 222. One end of the first support component 224 is rotatably connected to the adjusting component 223. One end of the second support component 225 is rotatably connected to the base 221, and the other end is rotatably connected to the other end of the first support component 224. When the adjusting component 223 moves, the other ends of the first support component 224 and the second support component 225 move towards or away from the transmission component 222, thus pushing against the inner wall of the pit 100. The above structure is not only simple and easy to operate and maintain, but also enables the support component 22 to provide dynamic support according to the deformation of the foundation pit 100, effectively preventing the deformation of the foundation pit 100 from exceeding the safe range. This avoids the problem of support failure caused by the inability of traditional fixed support methods to adapt to the dynamic changes of the foundation pit 100, and improves the accuracy and reliability of the deformation control of the foundation pit 100.

[0047] More specifically, in this embodiment, the transmission component 222 is a transmission rod, the first support component 224 is a first support rod, the second support component 225 is a second support rod, and the adjusting component 223 is a nut. The transmission rod is coaxially connected to the rotating shaft, and the nut is threadedly connected to the transmission rod. One end of the first support rod is hinged to the nut, and one end of the second support rod is hinged to the base 221, while the other end is hinged to the other end of the first support rod. When the rotating shaft rotates, causing the transmission rod to rotate around its own axis, the first support rod has a certain limiting effect on the nut, allowing the nut to move along the axial direction of the transmission rod. This causes the first and second support rods to contract or extend along the radial direction of the transmission rod. Through the threaded connection between the nut and the transmission rod, the extension and retraction of the first and second support rods can be precisely controlled, achieving fine adjustment of the support force on the inner wall of the pit 100.

[0048] In other embodiments, the transmission component 222 is a lead screw, the first support component 224 is a first support tube, the second support component 225 is a second support tube, and the adjusting component 223 is a rotating plate. The lead screw is coaxially connected to the rotating shaft, the rotating plate is rotatably connected to the lead screw, one end of the first support tube is rotatably connected to the rotating plate, one end of the second support tube is rotatably connected to the base 221, and the other end is rotatably connected to the first support tube. This also achieves dynamic support of the inner wall of the pit 100 by the support assembly 22. It is understood that the specific structure of the above components is not limited, as long as the above functions can be achieved.

[0049] Specifically, the support assembly 22 also includes a third support member 226, which is connected to the other end of the first support member 224 and the second support member 225. When the first support member 224 and the second support member 225 move, they drive the third support member 226 to move toward or away from the inner wall of the pit 100, so that the third support member 226 can directly abut against the inner wall of the pit 100 to control deformation, thereby further improving the deformation control effect of the pit 100.

[0050] More specifically, in this embodiment, the third support member 226 is a third support rod, one end of which is hinged to the other end of the first and second support rods. By the contraction or extension of the first and second support rods along the radial direction of the transmission rod, the other end of the third support rod abuts against the inner wall of the pit 100. This structure is simple and easy to implement, effectively improving the stability and reliability of the support assembly 22. In other embodiments, the third support member 226 is a third support tube. The specific structure of the third support member 226 is not limited here, as long as it can achieve the above-mentioned functions.

[0051] Specifically, the third support member 226 has an abutment portion 2261 at the end opposite to the first support member 224. The abutment portion 2261 can abut against the inner wall of the pit 100. This arrangement increases the contact area between the third support member 226 and the inner wall of the pit 100, improves the stability of the support, avoids the problem of uneven distribution of support force due to insufficient contact area, and further improves the effect of deformation control of the pit 100.

[0052] More specifically, in this embodiment, the abutment portion 2261 is a steel plate. The steel plate is used to abut against the inner wall of the supporting pit 100, which can provide more stable support and avoid the problem of insufficient support force. In other embodiments, the abutment portion 2261 may be a steel column. The specific structure of the abutment portion 2261 is not limited here.

[0053] Specifically, two first support members 224 and two second support members 225 are provided and symmetrically arranged on both sides of the transmission member 222, so that the support assembly 22 can maintain its own structural balance and stability during the process of being subjected to force, and avoid structural instability.

[0054] Specifically, the base 221 is equipped with rollers for rotation, which allows the support assembly 22 to move more flexibly.

[0055] More specifically, a support platform for supporting the support assembly 22 is fixedly provided inside the foundation pit 100 to ensure the safety of the operation. Moreover, the support mechanism 2 can adjust its position through rollers to meet the actual operation requirements.

[0056] Specifically, the control mechanism 3 includes a valve 31 and a control component 32. The valve 31 is located between the pressure-reducing well 200 and the support actuator 21. The control component 32 is communicatively connected to the valve 31 and the monitoring mechanism 1. When the control component 32 receives information from the monitoring mechanism 1, it controls the opening and closing of the valve 31 accordingly, thereby achieving precise control of the liquid flow direction. This improves the accuracy and reliability of the deformation control of the foundation pit 100 and avoids the impact of manual operation or untimely monitoring on the deformation control of the foundation pit 100.

[0057] Among them, valve 31 is selected as a solenoid valve or ball valve, and control component 32 is a microcontroller or PLC control system. The specific structure of valve 31 and control component 32 is not limited here, as long as the above functions can be achieved.

[0058] Specifically, when the liquid does not flow through the support actuator 21, the valve 31 can control the flow of liquid in the depressurization well 200 to the water tank 300. By setting the valve 31, the liquid can be rationally distributed, enabling the control mechanism 3 to utilize resources more efficiently and avoiding resource waste caused by liquid waste.

[0059] Specifically, in this embodiment, the monitoring mechanism 1 is a laser displacement meter. In other embodiments, the monitoring mechanism 1 may be a total station or an electronic level, as long as it can achieve real-time and accurate monitoring of the deformation of the foundation pit 100. The specific structure of the monitoring mechanism 1 is not limited here.

[0060] It should be noted that the foundation pit deformation control device in this embodiment can monitor and precisely control the deformation of the foundation pit 100 in real time. Especially under complex geological and hydrological conditions such as proximity to a river, traditional deformation control methods often struggle to address the problems caused by groundwater pressure and soil displacement. This device utilizes the monitoring mechanism 1 to monitor the deformation of the foundation pit 100 in real time, and drives the support assembly 22 to move via the support actuator 21 to dynamically support the inner wall of the foundation pit 100, effectively preventing excessive displacement and settlement of the inner wall of the foundation pit 100, ensuring the safety and stability of construction. Furthermore, the control mechanism 3 of this device reduces the difficulty of manual operation and technical requirements, providing reliable technical support for the construction of deep foundation pits 100 near rivers in subway projects, and contributing to the achievement of high-standard, high-quality engineering construction.

[0061] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make various obvious changes, readjustments, and substitutions without departing from the protection scope of this utility model. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
