Description

Technical Field

[0001] This utility model relates to the field of support device technology, specifically a deep foundation pit support device. Background Technology

[0002] Deep foundation pit support is an engineering technique that involves supporting, reinforcing, and protecting the sidewalls of a foundation pit to ensure the safety of underground structure construction and the surrounding environment. Its core objective is to prevent accidents such as collapse and water seepage, and to reduce the impact on adjacent buildings and underground facilities. The support scheme must be selected based on factors such as geological conditions and water level control. In projects with particularly complex geological conditions, surrounding environment, and underground pipelines, the design and construction of the support system is paramount in deep foundation pit engineering. Without a reliable support system, the excavation of a deep foundation pit will inevitably affect adjacent buildings or structures, and in severe cases, may even cause surface subsidence and structural collapse. Traditional deep foundation pit support methods often involve driving steel sheet piles tightly against the inner wall of the deep foundation pit, and then connecting the sheet piles together using I-beams in a U-shape or X-shape to form a stable structure. However, this method reduces the internal space of the deep foundation pit and affects other work processes. To improve this situation, a new deep foundation pit support device is proposed.

[0003] For example, the deep foundation pit support device disclosed in the authorization announcement number CN222541479U includes a support device body, the support device body includes a fixed seat and a movable seat, the movable seat has a limit groove, the fixed seat has a fixing groove, a fixing frame is movably installed inside the fixing groove, a tension mechanism is fixed to one end of the fixing frame, one end of the tension mechanism is fixed to the inner wall of the fixing groove, a support component is movably installed inside the fixing frame, and a positioning hole is opened at one end of both the fixed seat and the movable seat, and a positioning column is movably installed inside the positioning hole;

[0004] Although it allows the fixed bracket to enter the interior of the limiting groove during use, realizing the separation between the fixed seat and the movable seat, and installing the fixed seat and the movable seat together in a straight line, reducing the amount of storage space occupied and making it easy to store and move;

[0005] However, this does not solve the problem that the existing support devices are not conducive to modular assembly and use, and are not good at warning and protecting pedestrians and construction workers, which affects the convenience of assembly and the safety of construction. Utility Model Content

[0006] The purpose of this utility model is to provide a deep foundation pit support device to solve the problems mentioned in the background art, such as the support device being inconvenient to modularly assemble and use, not being conducive to warning and protecting pedestrians and construction workers, and affecting the convenience of assembly and the safety during construction.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a deep foundation pit support device, comprising an arc-shaped plate and first anchors, wherein the arc-shaped plate is in multiple sets, and the bottom end of each arc-shaped plate is provided with multiple sets of first anchors at equal intervals, and the interior of the arc-shaped plate is a hollow cavity, the top end of each arc-shaped plate is provided with a bearing plate, and the inner wall of each arc-shaped plate is provided with multiple sets of permeable plates at equal intervals, the top end of each bearing plate is provided with a warning light, the top end of the bearing plate on the side of the warning light is provided with a battery, the top end of the bearing plate on the side of the battery is provided with a water pump, and the bottom end of each water pump is provided with a water pumping pipe extending into the interior of the bearing plate, the top end of the bearing plate on the side of the water pump is provided with a photovoltaic power generation panel, and the electricity generated by the photovoltaic power generation panel irradiating the sun is stored in the battery, the side wall on one side of each arc-shaped plate is provided with a first limiting strip, and the side wall on the other side of each arc-shaped plate is provided with a first limiting groove, and the first limiting strip and the first limiting groove are slidably connected.

[0008] Preferably, the outer side of the arc-shaped plate is provided with steel sheet piles, and the bottom end of each steel sheet pile is provided with multiple sets of second anchors at equal intervals.

[0009] Preferably, each of the sheet piles has a symmetrically arranged insertion hole at its top, and each insertion hole has a connecting column inside it, with the connecting column slidably connected to the insertion hole.

[0010] Preferably, each of the connecting columns is provided with a placement hook on its side wall, and the steel sheet pile is provided with a protective plate on its exterior, which can be hooked onto the surface of the placement hook.

[0011] Preferably, the inner wall of each sheet pile is symmetrically provided with a second limiting strip, and the second limiting strip is fixedly connected to the sheet pile.

[0012] Preferably, the outer wall of the arc-shaped plate is symmetrically provided with second limiting grooves, and the second limiting strip is slidably connected to the second limiting grooves, and multiple sets of interlayer cavities are provided between the arc-shaped plate and the air pump.

[0013] Preferably, each of the interlayer cavities is provided with an airbag, and each airbag is provided with an air pump at its top.

[0014] Preferably, each of the water pumps is equipped with a drain pipe at its top, and the battery provides power to the warning light, water pump, and air pump.

[0015] Compared with the prior art, the beneficial effects of this utility model are: the support device not only realizes modular assembly and use, which facilitates warning and protection for pedestrians and construction workers, but also improves the convenience of assembly and the safety during construction.

[0016] (1) The four sets of arc-shaped plates are hoisted sequentially to the bottom away from the foundation pit wall. During the hoisting process, the first limiting strip needs to be aligned with the first limiting groove. The arc-shaped plates drive the first limiting strip to slide in the first limiting groove to assemble the four sets of arc-shaped plates into a cylinder. Because the circle has stability, it provides stable support for the overall device. The first anchor is inserted into the soil at the bottom of the foundation pit to prevent the arc-shaped plates from tilting. Then, the steel sheet piles are hoisted sequentially. The second limiting strip is aligned with the second limiting groove. The steel sheet piles drive the second limiting strip to slide in the second limiting groove to assemble multiple sets of steel sheet piles into an equilateral octagon. The second anchor is inserted into the soil at the bottom of the foundation pit to prevent the steel sheet piles from tilting. At this time, the steel sheet piles are assembled into an equilateral octagon. The sheet piles are positioned close to the inner wall of the foundation pit. The steel sheet piles and the curved plate are connected. Then, multiple sets of airbags are placed sequentially in the cavity between the steel sheet piles and the curved plate. The bearing plate and the electrical components on the bearing plate are installed on the curved plate. The battery provides power to the air pump, which inflates the airbags and fills the cavity. This allows the curved plate to be more tightly connected to the steel sheet piles, increasing the stability of the support structure and improving its support effect. The advantage of this design is that it can be modularly assembled and used. By utilizing the structural characteristics to ensure the stability of the support structure, it not only improves the convenience of assembly but also increases the construction space inside the foundation pit.

[0017] (2) The electricity generated by the photovoltaic panels irradiating the sun is stored in the battery, which powers the warning light to illuminate, thus alerting pedestrians at night. After the support device is assembled, groundwater below the pit will seep into the pit. The water in the pit enters the interior of the arc plate through the seepage plate. The water is pumped up through the water pipe and discharged through the drainage pipe, keeping the pit dry. The traditional method is to run an extra pipe into the pit, which takes up a lot of space and is inconvenient to use. When the workers leave the site after the day's construction work, the connecting column can be inserted into the insertion hole and the protective plate can be hooked on the placement hook. This can prevent people or animals from falling in and causing injury, and can also improve the safety during construction. This support device can warn and protect pedestrians and construction workers, thus improving their safety during construction. Attached Figure Description

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the scope of protection of the present utility model.

[0026] Please see Figure 1-6 This utility model provides an embodiment of a deep foundation pit support device, comprising an arc-shaped plate 3 and first footings 6. Multiple sets of arc-shaped plates 3 are provided, each with a set of equally spaced first footings 6 at its bottom end. The interior of each arc-shaped plate 3 is a hollow cavity. Each arc-shaped plate 3 has a bearing plate 10 at its top end. Multiple sets of equally spaced permeable plates 9 are provided on the inner wall of each arc-shaped plate 3. A warning light 13 is provided at the top end of each bearing plate 10. A battery 14 is provided on the top end of each bearing plate 10 on one side of the warning light 13. Each of the support plates 10 is equipped with a water pump 15 at its top and a water pump 12 at its bottom, which extends into the interior of the support plate 10. A photovoltaic power generation panel 16 is provided on the top of the support plate 10 on one side of the water pump 15, and the electricity generated by the photovoltaic power generation panel 16 irradiating the sun is stored in the battery 14. A first limiting strip 11 is provided on one side wall of the arc plate 3, and a first limiting groove 17 is provided on the other side wall of the arc plate 3, and the first limiting strip 11 and the first limiting groove 17 are slidably connected.

[0027] During the foundation pit support construction, four sets of arc-shaped plates 3 are first hoisted sequentially to the bottom away from the foundation pit wall. During the hoisting process, the first limiting strip 11 needs to be aligned with the first limiting groove 17. Under the sliding cooperation of the first limiting strip 11 and the first limiting groove 17, and with the support of the self-weight of the arc-shaped plates 3, the arc-shaped plates 3 drive the first limiting strip 11 to slide within the first limiting groove 17, thereby assembling the four sets of arc-shaped plates 3 into a cylinder. Because the circle has stability, it provides stable support for the overall device. The first anchor 6 is inserted deep into the soil at the bottom of the foundation pit to prevent the arc-shaped plates 3 from tipping over. Then, the steel sheet piles 1 are hoisted sequentially, and the second limiting strip 20 is aligned with the second limiting groove 18. Under the sliding cooperation of the second limiting strip 20 and the second limiting groove 18, and with the support of the self-weight of the steel sheet piles 1, the steel sheet piles 1 drive the second limiting strip 20 to slide within the second limiting groove 18, so that... Multiple sets of sheet piles 1 are assembled into an equilateral octagon. The second anchor 8 is inserted into the soil at the bottom of the foundation pit to prevent the sheet piles 1 from tilting. At this time, the sheet piles 1 are in a position close to the inner wall of the foundation pit. The sheet piles 1 and the arc plate 3 are connected. Then, multiple sets of airbags 4 are placed in the interlayer cavity 22 between the sheet piles 1 and the arc plate 3. The bearing plate 10 and the electrical components on the bearing plate 10 are installed on the arc plate 3. The battery 14 provides power to the air pump 7, which inflates the airbags 4, causing them to expand and fill the interlayer cavity 22. This makes the arc plate 3 and the sheet piles 1 more tightly connected, thereby increasing the stability of the support structure and improving its support effect. The advantage of this design is that it can be modularly assembled and used. By utilizing the structural characteristics to ensure the stability of the support structure, it not only improves the convenience of assembly but also increases the construction space inside the foundation pit.

[0028] All of the curved plate 3 is equipped with steel sheet piles 1, and the bottom of each steel sheet pile 1 is equipped with multiple sets of second anchors 8 at equal intervals.

[0029] The top of each sheet pile 1 is symmetrically provided with insertion holes 19, and each insertion hole 19 is provided with a connecting column 5. The connecting column 5 is slidably connected to the insertion hole 19. Each connecting column 5 is provided with a placement hook 21 on its side wall. The sheet pile 1 is provided with a protective plate 2 on its exterior, and the protective plate 2 can be hooked onto the surface of the placement hook 21.

[0030] The inner wall of the sheet pile 1 is symmetrically provided with second limiting strips 20, and the second limiting strips 20 are fixedly connected to the sheet pile 1.

[0031] The outer wall of the arc plate 3 is symmetrically provided with second limiting grooves 18, and the second limiting strip 20 is slidably connected to the second limiting groove 18. Furthermore, multiple sets of interlayer cavities 22 are provided between the arc plate 3 and the air pump 7.

[0032] The interior of the interlayer cavity 22 is equipped with an airbag 4, the top of the airbag 4 is equipped with an air pump 7, the top of the water pump 15 is equipped with a drain pipe 23, and the battery 14 provides power support for the warning light 13, the water pump 15 and the air pump 7.

[0033] In daily use, the electricity generated by the photovoltaic panel 16 irradiating the sun is stored in the battery 14, which powers the warning light 13 to illuminate, thus alerting pedestrians at night. After the support device is assembled, groundwater below the pit will seep into the pit. The water in the pit enters the interior of the arc plate 3 through the seepage plate 9. The water pump 15 is turned on, and the water is pumped up through the water pipe 12 and discharged through the drainage pipe 23, keeping the pit dry. The traditional method is to run an extra pipe in the pit, which takes up a lot of space and is inconvenient to use. When the construction work is finished and the workers leave the site, the connecting column 5 can be inserted into the insertion hole 19, and the protective plate 2 can be hooked onto the placement hook 21. This can prevent people or animals from falling in and causing injury, and can also improve the safety during construction. This support device can warn and protect pedestrians and construction workers, thus improving their safety during construction.

[0034] Working principle: During the foundation pit support construction, four sets of arc-shaped plates 3 are first hoisted sequentially to the bottom away from the foundation pit wall. During the hoisting process, the first limiting strip 11 needs to be aligned with the first limiting groove 17. The arc-shaped plates 3 drive the first limiting strip 11 to slide within the first limiting groove 17, thereby assembling the four sets of arc-shaped plates 3 into a cylinder. Due to the stability of the circle, this provides stable support for the overall device. The first anchor 6 is deeply embedded in the soil at the bottom of the foundation pit to prevent the arc-shaped plates 3 from tipping over. Then, steel plates are hoisted sequentially. With sheet pile 1 in place, the second limiting strip 20 is aligned with the second limiting groove 18. The sheet pile 1 drives the second limiting strip 20 to slide inside the second limiting groove 18, assembling multiple sets of sheet piles 1 into an equilateral octagon. The second anchor 8 is inserted deep into the soil at the bottom of the foundation pit to prevent the sheet pile 1 from tilting. At this time, the sheet pile 1 is in a position close to the inner wall of the foundation pit, and the sheet pile 1 and the arc plate 3 are connected. Then, multiple sets of airbags 4 are placed sequentially in the interlayer cavity 22 between the sheet pile 1 and the arc plate 3, and the bearing plate 10 and the bearing plate 10 are placed in place. The electrical components are mounted on the curved plate 3. The air pump 7 is powered by the battery 14, which inflates the airbag 4, filling the interlayer cavity 22. This allows for a tighter connection between the curved plate 3 and the sheet pile 1. The electricity generated by the photovoltaic panel 16 is stored in the battery 14, which powers the warning light 13 to illuminate, providing a warning to pedestrians at night. After the support device is assembled, groundwater below the pit will seep into... Inside the foundation pit, water enters the interior of the arc-shaped plate 3 through the seepage plate 9. The water is then pumped up by the water pump 15 through the water extraction pipe 12 and discharged through the drainage pipe 23, keeping the foundation pit dry. Traditional methods often involve pulling an extra pipe into the foundation pit, which takes up a lot of space and is inconvenient to use. When the workers leave the site after the day's construction work is completed, the connecting column 5 can be inserted into the insertion hole 19, and the protective plate 2 can be hooked onto the placement hook 21. This can prevent people or animals from falling in and getting injured.
