Description

Technical Field

[0001] This utility model belongs to the field of construction safety equipment technology, specifically a safety fence suitable for the protection of excavated foundations. Background Technology

[0002] Safety fences, as crucial protective facilities in foundation construction areas of building projects, primarily function to isolate hazardous areas, warn personnel, and prevent interference from the external environment. Currently, most common fence products on the market are designed for flat sites or standardized foundation pits. However, in complex terrain scenarios such as mountainous foundation excavations, existing technologies have significant shortcomings. First, traditional fences often employ fixed structures with adjustable leg height and deployment angles, making them ill-suited to the undulating terrain of mountainous areas. Uneven support surfaces during installation can easily cause the fence to tilt or even collapse, reducing protective reliability and potentially creating secondary safety hazards. Second, conventional fences are bulky and their components are heavy, making transportation to remote mountainous construction areas costly and assembly cumbersome, hindering rapid deployment. Furthermore, existing fences lack sufficient wind resistance, especially in open mountainous environments where strong winds can easily topple the fence structure. The standard simple reflective strips or warning signs suffer significant reduction in visibility under low-visibility conditions such as rain, fog, and nighttime, weakening their warning effect. More importantly, the existing fences lack the ability to actively protect against natural climate changes. During rainfall, rainwater seeps directly into the foundation pit, causing the soil on the pit walls to soften, the slopes to become unstable, or even collapse, seriously affecting construction safety and progress.

[0003] While some improved fencing designs attempt to address these shortcomings by adding counterweights, reinforcing the frame, or adding rain shelters, significant limitations remain. For example, counterweights increase the burden of transportation and installation, reinforcing the frame sacrifices flexibility, and external rain shelters are structurally complex and susceptible to wind damage. These solutions fail to systematically address the integrated needs for terrain adaptability, portability, wind resistance, and rain protection, thus limiting their application. Therefore, there is an urgent need for a safety fence that combines height adjustability, rapid assembly, environmental adaptability, and multi-dimensional protection to meet the complex and varied challenges of foundation excavation in mountainous terrain, while simultaneously reducing construction risks and improving protective efficiency. Utility Model Content

[0004] To address the inconvenience of assembling and using safety protection for excavated foundations in mountainous areas, this utility model provides a safety fence suitable for the protection of excavated foundations.

[0005] This utility model is achieved through the following technical solution:

[0006] A safety fence suitable for excavation foundation protection includes a top connecting plate, on which at least three retractable legs are evenly distributed. The retractable legs are hinged to the top connecting plate via leg connecting shafts. A rain cover is connected between two adjacent retractable legs, and the rain cover is provided with reflective strips. A warning device is provided on the top connecting plate.

[0007] The retractable outriggers break through the limitations of traditional fixed structures, allowing for flexible adjustment of height and angle to perfectly adapt to the undulating terrain of mountainous areas. This fundamentally solves the problem of fence tilting or collapsing due to uneven support surfaces, greatly enhancing protective reliability, avoiding secondary safety hazards, and facilitating storage and assembly. The rain-shielding tarpaulin actively prevents rainwater from directly entering the foundation pit, effectively avoiding risks such as soil softening and slope instability, ensuring construction safety and progress. The reflective strips and warning devices work together to provide a warning effect in low-light conditions, effectively isolating dangerous areas and preventing people from accidentally entering.

[0008] A further improvement of this utility model is that the aforementioned telescopic outrigger includes an outer sleeve and an inner connecting rod slidably disposed within the outer sleeve; the outer sleeve is provided with an outrigger adjustment knob capable of locking the extension of the inner connecting rod beyond the length of the outer sleeve. Construction personnel can precisely and flexibly adjust the outrigger height according to the site terrain, achieving stable installation in complex terrains such as mountainous areas, greatly improving terrain adaptability; moreover, in different construction scenarios, the outrigger length can be quickly adjusted to meet rapid deployment requirements, easily overcoming the cumbersome assembly problems of traditional fences and significantly improving assembly efficiency.

[0009] A further improvement of this invention is that the end of the aforementioned inner connecting rod is provided with a leg tip that facilitates insertion into the construction ground. This allows it to easily penetrate soft or uneven mountain soil and other construction surfaces, significantly increasing the anchoring force between the leg and the ground, further enhancing the stability of the fence in complex terrain, ensuring the fence is firmly rooted, undaunted by terrain challenges, and continuously safeguarding construction safety.

[0010] A further improvement of this invention is that the end of the aforementioned inner connecting rod is provided with a foot pedal to facilitate the insertion of the outrigger tip into the construction ground. During installation, construction workers can easily and quickly insert the outrigger tip into the ground by using the foot pedal, greatly simplifying the installation process, reducing the intensity of manual operation, and effectively promoting the rapid assembly process, thus meeting the demand for efficient operation in mountainous construction.

[0011] A further improvement of this invention is that the aforementioned warning device is a solar-powered warning light. Compared to traditional simple reflective strips or warning signs, it can actively emit light in adverse conditions of low visibility such as rain, fog, and night, significantly improving warning visibility and making dangerous areas immediately apparent. At the same time, the solar power supply is green and environmentally friendly, requiring no external power source, effectively enhancing environmental adaptability and reducing reliance on complex construction environments.

[0012] A further improvement of this invention is that the bottom edge of the aforementioned rainproof tarpaulin is connected to an extension portion with a fan-shaped structure. Firstly, this significantly increases the tarpaulin's coverage area, efficiently guiding rainwater away along the edges and reducing the possibility of rainwater seeping into the foundation pit at the source, thus significantly enhancing its rainproof function. Secondly, the tarpaulin's arc-shaped edge, located between adjacent support legs, provides comprehensive active protection for the foundation pit, effectively mitigating the adverse effects of rainfall on construction safety and progress.

[0013] A further improvement of this utility model is that the outer edge of the aforementioned extension portion is provided with a through tube, and a support rod is inserted through the through tube. The two ends of the support rod are detachably connected to two connected retractable legs. The support rod passes through the through tube of the extension portion, forming edge support for the extension portion, allowing for the use of nearby heavy objects to cover it, thus achieving good support and coverage. The detachable connection between the support rod and the retractable legs facilitates storage and assembly.

[0014] A further improvement of this invention is that the aforementioned support rod is made of elastic polyurethane material. When strong winds occur, it can fully utilize its elastic properties to absorb the impact of the strong winds and cleverly disperse the wind force through flexible deformation, significantly improving the wind resistance stability of the fence. Simultaneously, the support rod works in conjunction with the extension section to keep the tarpaulin taut at all times, effectively preventing rainwater from accumulating on the tarpaulin surface and further enhancing the rainproof effect.

[0015] As can be seen from the above technical solutions, the beneficial effects of this utility model are as follows: the telescopic outriggers break through the limitations of traditional fixed structures, can flexibly adjust the height and angle, perfectly adapt to the undulating changes of mountainous terrain, fundamentally solve the problem of fence tilting or falling due to uneven support surfaces, greatly enhance the reliability of protection, avoid secondary safety hazards, and facilitate storage and assembly; the rainproof tarpaulin actively prevents rainwater from directly entering the foundation pit, effectively avoiding risks such as soil softening of the pit wall and slope instability, ensuring construction safety and progress; the reflective strips and warning devices work together to play a warning role in poor lighting conditions, effectively isolating dangerous areas and preventing people from accidentally entering.

Detailed Implementation

[0022] To make the objectives, features, and advantages of this utility model more apparent and understandable, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings of the specific embodiments. Obviously, the embodiments described below are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.

[0023] like Figures 1-4 As shown, this utility model discloses a safety fence suitable for excavation foundation protection, including a top connecting plate 40, on which at least three retractable legs 10 are evenly distributed. The retractable legs 10 are hinged to the top connecting plate 40 via a leg connecting shaft 50. A rain cover 20 is connected between two adjacent retractable legs 10, and the rain cover 20 is provided with reflective strips 21. The retractable legs 10 break through the limitations of traditional fixed structures, and can flexibly adjust their height and angle to perfectly adapt to the undulating changes of the mountainous surface. This fundamentally solves the problem of fence tilting or falling due to uneven support surfaces, greatly enhances the reliability of protection, avoids secondary safety hazards, and is also easy to store and assemble. The rain cover 20 actively prevents rainwater from directly entering the foundation pit, effectively avoiding risks such as soil softening and slope instability, and ensuring construction safety and progress.

[0024] The outrigger connecting shaft 50 is also provided with a locking member that can fix the angle between the retractable outrigger 10 and the top connecting plate 40, thereby improving the stability and support performance.

[0025] The retractable outrigger 10 includes an outer sleeve 15 and an inner connecting rod 16 slidably disposed within the outer sleeve 15. The outer sleeve 15 is equipped with an outrigger adjustment knob 11 that locks the extension of the inner connecting rod 16 beyond the outer sleeve 15. Construction personnel can precisely and flexibly adjust the outrigger height according to the site terrain, achieving stable installation in complex terrains such as mountainous areas, greatly improving terrain adaptability. Furthermore, the outrigger length can be quickly adjusted in different construction scenarios to meet rapid deployment requirements, easily overcoming the cumbersome assembly of traditional fences and significantly improving assembly efficiency.

[0026] The bottom edge of the tarpaulin 20 is connected to a fan-shaped extension 22. A through-tube 23 is provided along the outer edge of the extension 22, and a support rod 24 passes through the through-tube 23. Both ends of the support rod 24 are detachably connected to two connected retractable legs 10. Firstly, this significantly increases the tarpaulin's coverage area, efficiently guiding rainwater away along the edges and reducing the possibility of rainwater seeping into the foundation pit, thus significantly enhancing its rainproof function. Secondly, the tarpaulin covers the arc-shaped edge of the foundation pit located between adjacent legs, providing comprehensive active protection and effectively resisting the adverse effects of rainfall on construction safety and progress. The support rod 24 passes through the through-tube 23 of the extension 22, forming edge support for the extension 22, allowing for the use of nearby heavy objects to weigh it down, achieving good support and coverage. The detachable connection between the support rod 24 and the retractable legs 10 facilitates storage and assembly.

[0027] Specifically, the inner connecting rod 16 has a mounting hole 14 for inserting the support rod 24, which is then inserted into the mounting hole 14. The support rod 24 is made of elastic polyurethane material. In the event of strong winds, it fully utilizes its elastic properties to absorb the impact of the wind and cleverly disperses the wind force through flexible deformation, significantly improving the wind resistance stability of the fence. Simultaneously, the support rod 24 works in conjunction with the extension part 22 to keep the tarpaulin taut at all times, effectively preventing rainwater from accumulating on the tarpaulin surface and further enhancing the rainproof effect.

[0028] The tube 23 is also equipped with straps. Heavy objects retrieved from the surrounding area can be tied together with the straps to improve wind resistance.

[0029] The inner connecting rod 16 has a leg tip 13 at its end for easy insertion into the construction ground. It can easily penetrate into soft or uneven mountain soil and other construction ground, significantly increasing the anchoring force between the leg and the ground, further strengthening the stability of the fence in complex terrain, allowing the fence to be firmly rooted, fearless of terrain challenges, and continuously safeguarding construction safety.

[0030] The inner connecting rod 16 is equipped with a foot pedal 12 at its end, which facilitates the insertion of the outrigger tip 13 into the ground. During installation, construction workers can easily and quickly insert the outrigger tip 13 into the ground by using the foot pedal 12, which greatly simplifies the installation process, reduces the intensity of manual operation, and promotes rapid assembly, thus meeting the needs of high-efficiency operation in mountain construction.

[0031] A warning device 31 is installed on the top connecting plate 40. The reflective strip 21 works in conjunction with the warning device 31 to provide a warning in low-light conditions, effectively isolating dangerous areas and preventing accidental entry. The warning device 31 is a solar-powered warning light 30, which has a built-in battery that converts solar energy into electricity. Compared to traditional simple reflective strips 21 or warning signs, it actively emits light in low-visibility conditions such as rain, fog, and nighttime, significantly improving warning visibility and making dangerous areas clearly visible. Simultaneously, the solar power supply is green and environmentally friendly, requiring no external power source, effectively enhancing environmental adaptability and reducing reliance on complex construction environments.

[0032] This utility model describes a safety fence suitable for excavation foundation protection. Its retractable legs break through the limitations of traditional fixed structures, allowing for flexible adjustment of height and angle to perfectly adapt to the undulating terrain of mountainous areas. This fundamentally solves the problem of fence tilting or collapsing due to uneven support surfaces, greatly enhancing protective reliability, avoiding secondary safety hazards, and facilitating storage and assembly. The rainproof tarpaulin actively prevents rainwater from directly entering the foundation pit, effectively avoiding risks such as soil softening and slope instability, ensuring construction safety and progress.
