Description

Technical Field

[0001] The invention belongs to the technical field of foundation pit stabilization, and in particular relates to a multi-angle adjustable highway foundation pit stabilization device. Background Art

[0002] In the field of foundation pit engineering technology, the stability maintenance of highway foundation pits has always been the focus of engineers. With the rapid development of transportation infrastructure construction, the excavation depth and width of highway foundation pits are constantly increasing, and the requirements for the stability of foundation pits are also increasing. Traditional foundation pit stabilization methods mainly rely on structural forms such as soil nail walls, steel sheet piles, and underground continuous walls.

[0003] First of all, traditional foundation pit stabilization structures often lack adjustability. Once the size, shape or depth of the foundation pit changes, it needs to be redesigned and constructed, which not only increases the project cost but also prolongs the construction period. In addition, traditional foundation pit stabilization methods can usually only provide a single support method, which is difficult to adapt to the needs of different geological conditions and foundation pit shapes. For example, in areas with complex geological conditions and uneven soil strength, traditional foundation pit stabilization structures often cannot achieve the ideal stabilization effect, resulting in poor use of the device, so staff need to improve it. Summary of the invention

A first screw rod is fixedly connected to one side of the first transmission gear, and a first sleeve is threadedly connected to the surface of the first screw rod, and the surface of the first sleeve is fixedly connected to the inner wall of the extension plate.

[0010] Preferably, a second driving gear is fixedly connected to the surface of the driving rod, second transmission gears are meshedly connected to the surface of the second driving gear around four sides, and a movable rod is fixedly connected to one side of the second transmission gear.

[0015] Preferably, the bottom of the cross mounting frame is fixedly connected to limiting brackets around its periphery, the bottom of the limiting bracket is slidably connected to a limiting frame, and the bottom of the limiting frame is fixedly connected to the surface of the second sleeve.

[0018] Preferably, reinforcement plates are fixedly connected to the four sides of the cross mounting frame, connecting brackets are fixedly connected to the surfaces of the reinforcement plates, and fixing bolts are threadedly connected to the tops of the reinforcement plates and the connecting brackets.

[0019] Compared with the prior art, the present invention has the following beneficial effects:

[0020] (1) Compared with the existing foundation pit stabilization methods that mainly rely on soil nail walls, steel sheet piles, underground continuous walls and other structural forms and lack adjustability, the present invention realizes multi-angle adjustment of the bottom of the foundation pit and expansion of the stable area through the comprehensive arrangement of threaded sleeves, fixed bottom plates, sleeve frames, extension plates, pads, connecting rods, first driving gears, first transmission gears, first screw rods and first sleeves. Specifically, the driving rod drives the threaded rod to rotate, and then drives the threaded sleeve and the fixed bottom plate to adjust the height, so that the fixed bottom plate and the pads at the four sides are overlapped at the bottom of the foundation pit. At the same time, the threaded rod drives the connecting rod to rotate, further driving the first driving gear, the first transmission gear and the first screw rod to work, so that the extension plate moves outward, and the contact area between the pad plate and the bottom of the foundation pit is expanded, thereby enhancing the stability of the bottom of the foundation pit. This design of multi-angle adjustment and expansion of the stable area enables the device to adapt to foundation pits of different sizes, shapes and depths, thereby improving the applicability and stabilization effect of the device.

[0021] (2) The existing pit stabilization methods can usually only provide a single support method, which is difficult to adapt to the needs of different geological conditions and pit shapes. The present device realizes flexible support enclosure and real-time pressure monitoring around the pit by setting a driving rod, a baffle, a telescopic bracket, a hydraulic rod and a pressure sensor. The rotation of the driving rod not only drives the rotation of the threaded rod to achieve height adjustment, but also transmits power through the second driving gear fixed on its surface to drive the second transmission gear, the movable rod, the second screw rod and the second sleeve to work, so that the baffle and the telescopic bracket connected thereto change position, adjust the support angle and range, and the telescopic function of the hydraulic rod further adjusts the support strength and stability of the telescopic bracket, while the pressure sensor monitors the pressure borne by the hydraulic rod in real time to ensure that the device operates within a safe range. The flexible support enclosure and real-time pressure monitoring function improve the adaptability and safety of the device.

[0022] (3) Energy conservation and environmental protection as well as enhanced overall stability of the device are achieved through the arrangement of a cross mounting frame, a bearing ring, a limit bracket, a limit frame, a battery box, a positioning bracket, a photovoltaic panel, a reinforcement plate, a connecting bracket and fixing bolts. The battery arranged inside the battery box provides power for electrical equipment such as a servo motor, thereby ensuring the continuous operation of the device. The photovoltaic panel fixedly connected to the top of the battery box through the positioning bracket can generate electricity using solar energy to charge the battery, thereby achieving energy conservation and environmental protection of the device. At the same time, the reinforcement plates fixedly connected around the cross mounting frame are fixedly connected to the surrounding environment through connecting brackets and fixing bolts, thereby enhancing the overall stability and wind resistance of the device. This energy-saving, environmentally friendly and reinforced design enables the device to better adapt to various complex environments and improves the reliability and service life of the device.
