It is an essential part of the construction process and plays a vital role in maintaining the stability of high-rise buildings. During the construction process, guardrails are required to surround the pit to ensure the safety of pedestrians and vehicles passing by, while also further speeding up the pit operation.

[0003] In the related technologies of foundation pit guardrails, most foundation pit guardrails are rigid structures, which are mainly divided into two types: one-piece and detachable. One-piece guardrails are formed by processing galvanized pipes or steel pipes layer by layer. They are usually large in size, which often causes inconvenience during transportation; and their versatility is poor; detachable guardrails improve efficiency during transportation by disassembling and installing the base and the vertical guardrail body, but the installation process is relatively more complicated and takes a lot of time. In addition, because it is a rigid protection, when a vehicle collides with the guardrail, it usually damages the vehicle, causing property loss, and easily causes secondary injuries to the vehicle and workers.

[0004] It can be seen that the existing foundation pit guardrails usually adopt a rigid structure, which is easy to cause damage to vehicles and workers, resulting in poor safety. Utility Model Content

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The utility model provides a combined foundation pit guardrail. This guardrail realizes the flexible construction of the guardrail by introducing a combined design of vertical poles and steel cable equipment. The limiting holes opened on the vertical poles enable the steel cable equipment to easily connect the vertical poles to form a stable protection area, which not only simplifies the installation process and reduces installation time and cost, but also significantly improves the versatility and adaptability of the guardrail. The use of steel wire rope as a connecting element replaces the traditional rigid structure, so that the guardrail can better absorb and disperse the impact force when it is hit by a vehicle, thereby reducing damage to the vehicle, reducing property loss and the risk of secondary injury to the vehicle and workers. The use of this guardrail not only improves the safety of the foundation pit guardrail, but also improves the transportation efficiency and construction efficiency; it is of great significance to the improvement and development of the foundation pit guardrail.

[0049] The present invention is described in further detail below with reference to the accompanying drawings:

[0050] Example

[0051] As mentioned in the background technology, traditional foundation pit guardrails usually adopt a rigid structure, which can easily cause damage to vehicles and workers, resulting in poor safety; moreover, the integrated structure is not convenient for installation, disassembly and transportation, which greatly affects the efficiency of transportation and construction.

[0052] In order to solve the above problems, this embodiment provides a combined foundation pit guardrail. The combined foundation pit guardrail can be used to conveniently connect the steel cable equipment with the vertical pole to form a flexible protective whole. It is easy to operate and has high work efficiency. It can also replace rigid protection with flexible protection to reduce economic losses caused by vehicle collisions.

[0053] like Figure 1 As shown, this embodiment provides a combined foundation pit guardrail, including several upright poles 1, the number of upright poles 1 is at least two, and in order to facilitate the disassembly of the whole, there is a double-layer fastening thread at the bottom of the upright pole 1 that can be connected to the base 2, and each upright pole 1 is provided with a plurality of connection and passing devices for fixing the steel cable equipment 4 to form a transverse flexible protective wire rope 8, and then form a wire rope loop to enclose the foundation pit protection area; in this embodiment, the protection level of the guardrail can be improved by adding upright pole 1 connection and passing devices or changing the diameter of the wire rope 8, so as to achieve the purpose of better protecting the foundation pit operation.

[0054] The bottom of the vertical pole 1 has a double-layer fastening thread, wherein the upper thread 6 of the double-layer fastening thread is connected to the internal threaded column 11 of the base. In a harder geological environment, the base 2 is fixed to the ground with expansion screws to achieve the purpose of fixing the vertical support of the guardrail. The lower thread 7 of the double-layer fastening thread can be connected to a variety of end heads. On harder ground, a flat-bottom joint 5 is used to prevent fine sand and stone particles from entering the gap between the lower thread 7 and the internal threaded column 11 of the base, thereby increasing the service life of the guardrail. On softer ground such as sand, stone and soil, a pointed pile joint 3 is used to replace the flat-bottom joint 5 to connect the vertical pole 1, and then the vertical pole 1 is connected to the base 2. The formed whole is tightly connected to the ground by plugging; selecting different end heads according to different geological conditions can further improve the applicability and flexibility of the guardrail.

[0055] In this embodiment, in order to improve the adaptability of the guardrail, when performing the operation, it should be determined whether the construction geology is suitable for inserting the foundation pit with pointed piles. If the geology cannot be used to insert the pointed piles, Figure 9 As shown, the base 2 should be fixed with expansion screws in the base limit holes 9 of the base 2, and then the upper thread 6 of the double-layer fastening thread of the vertical pole 1 should be connected to the internal thread column 11 of the base. Once the base 2 is fixed, it does not need to be removed before the overall construction is completed. In the event that the guardrail needs to be temporarily removed, the base 2 and the vertical pole 1 can be separated by threads. When the geology allows the insertion of pointed piles, the pointed pile joint 3 is connected to the lower thread 7 of the double-layer fastening thread of the vertical pole 1 to ensure that the overall structure is tight before inserting it into the soil. At this time, expansion screws are not required.

[0056] In this embodiment, in order to save manufacturing costs and facilitate transportation, the upright pole 1 is a hollow structure, which reduces weight while ensuring safety performance and further improves transportation efficiency.

[0057] The steel wire rope 8 of the steel cable equipment 4 serves as a combined guardrail lateral protection measure, providing flexible protection to ensure the safety of foundation pit operations.

[0058] In order to allow the wire rope 8 to be freely extended or shortened, a roller 13 is provided inside the wire rope device body of the wire rope device 4. One end of the wire rope 8 is fixed on the roller 13. The purpose of extending or shortening the wire rope 8 can be achieved by rotating the roller 13.

[0059] In order to prevent the steel wire rope 8 from moving when the predetermined steel wire rope length is reached, a buckle 14 is provided on the steel wire rope device 4 to match the protrusion of the roller 13. By laterally buckling the buckle 14, the roller 13 can be fixed, thereby locking the length of the steel wire rope 8.

[0060] In order to ensure that the guardrail situation can be received in time, an alarm 18 is equipped on the steel cable device 4. The bolt 16 at the end of the steel cable is fixed to the receiving end 12 of the steel cable device. After the buckle 14 is locked, the stretched wire rope 8 will trigger the alarm 18.

[0061] In this embodiment, in order to ensure the connection between the steel cable device 4 and the vertical pole 1, the steel cable device output end 15 of the steel cable device 4 can be fixed on the vertical pole 1 through the connecting device to ensure the stability of the overall structure.

[0062] In this embodiment, after the output end 15 of the steel cable device is fixed to the limiting hole 10 of the vertical pole, the steel wire rope 8 is stretched so that the steel cable passes through the limiting holes 10 of the same horizontal vertical pole of several vertical poles 1 in sequence, and finally connected to the receiving end 12 of the steel cable device. The steel cable end bolt 16 at the end of the steel cable is connected to the receiving end 12 of the steel cable device, and the buckle 14 is locked. According to the above method, multiple steel cable devices 4 are installed to form a flexible horizontal protection.

[0063] like Figure 1 As shown, this embodiment provides a combined foundation pit guardrail, comprising at least two vertical poles 1 and the same number of bases 2 as the vertical poles 1. Each base 2 is equipped with a variety of end caps, and each group of guardrails includes a plurality of steel cable devices 4.

[0064] The connection mechanism provided in this embodiment includes expansion screws for fixing the ground and the base 2 on the concrete ground, a variety of ends for connecting with the ground on different types of geological ground, a lower thread 7 connecting the various ends and the vertical pole 1, an upper thread 6 connecting the vertical pole 1 and the base 2, a steel cable device output end 15 for fixing the steel cable device 4 on the vertical pole 1 and a vertical pole limiting hole 10. In order to prevent the steel cable device 4 from falling off from the vertical pole 1, a limiting nut 17 is provided at the steel cable device output end 15, a roller 13 with a protrusion of the steel cable device and a buckle 14 adapted thereto, a steel cable end bolt 16 and a corresponding steel cable device receiving end 12.

[0065] like Figure 2 and Figure 3 As shown, the lower thread 7 of the double-layer fastening thread at the bottom of the vertical pole 1 provided in this embodiment is connected to the pointed pile joint 3, and then the vertical pole 1 and the pointed pile joint 3 formed by the connection are connected to the base internal thread column 11 of the base 2 through the upper thread 6. The final whole formed by the vertical pole 1, the pointed pile joint 3 and the base 2 is fully plugged into the ground, wherein the base 2 can serve as the force point of the whole, which facilitates the pointed pile part of the pointed pile joint 3 to be stably inserted into the ground, which is a relatively soft soil ground.

[0066] like Figure 4 and Figure 5 As shown, the base 2 provided in this embodiment is first fixed to the concrete ground by expansion screws. Before the overall foundation pit construction is completed, the base 2 does not need to be removed, and then the lower thread 7 of the vertical pole 1 is connected to the flat bottom joint 5 to prevent small sand and stone particles from entering the guardrail connection part, thereby improving the service life of the guardrail. Finally, the vertical pole 1 is connected to the base 2. In subsequent use, the vertical pole 1 and the base 2 can be disconnected or connected by threads to achieve the purpose of maintaining stability while facilitating disassembly.

[0067] Combine Figure 6 、 Figure 7 and Figure 8 As shown, the steel cable device 4 provided in this embodiment has a rotatable roller 13 with a protrusion inside, one end of the steel wire rope 8 is tightly connected to the roller 13, and the other end is connected to the steel cable end bolt 16, and the purpose of controlling the extension and contraction distance of the steel cable is achieved by braking the roller 13 through the buckle 14. Finally, after passing through the vertical pole limiting holes 10 of several vertical poles 1, the steel cable end bolt 16 is connected back to the steel cable device receiving end 12 to achieve the effect of maintaining overall stability. After the connection is completed, it is locked by the buckle 14; the steel cable device 4 is equipped with an alarm 18, and the steel wire rope 8 can be stretched to trigger the alarm, so that dangerous situations can be discovered in time and an alarm reminder can be issued.

[0068] In summary, this embodiment provides a combined foundation pit guardrail, which has the following advantages:

[0069] First, by using convenient steel cable equipment, poles, and bases to form a combined foundation pit guardrail, while ensuring the protection capability, the steel cable equipment is used instead of the guardrail body as a horizontal protection, reducing the overall space occupied by the guardrail, improving transportation efficiency, and improving foundation pit operation efficiency;

[0070] Second, by replacing the bottom end of the vertical pole, the combined foundation pit guardrail can be applied to a variety of ground surfaces, thereby effectively improving the flexibility and applicability of the combined foundation pit guardrail during use while ensuring safe operation;

[0071] Third, by using steel cable equipment to replace the traditional horizontal guardrail body, and flexible protection instead of rigid protection, the safety of foundation pit work can be protected by the tension formed by the steel cable, which can more effectively protect the safety of colliding vehicles, prevent secondary injuries, and reduce the economic losses caused by collisions.

[0072] The above embodiment is only one of the implementation methods that can realize the technical solution of the present invention. The scope of protection claimed by the present invention is not limited only to this embodiment, but also includes within the technical scope disclosed by the present invention, any changes, replacements and other implementation methods that can be easily thought of by any technician familiar with this technical field.
