Description

Technical Field

[0001] This utility model relates to the field of bored piles, and in particular to a protective device for manually excavated bored piles. Background Technology

[0002] Manual excavation of bored piles is a common construction method in power engineering.

[0003] However, there are several problems with manually excavating bored piles. Although workers wear safety belts, the lack of enclosure during operation poses a risk of falls for construction or management personnel. Furthermore, there are no anchor points for fall arrestors when workers go up or down the shaft, creating safety hazards during construction. Therefore, we propose a protective device for manually excavated bored piles to solve these problems. Utility Model Content

[0004] The purpose of this utility model is to provide a protective device for manually excavated bored piles to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A protective device for manually excavated bored piles includes an embedded fence, with a bored pile well located below the embedded fence. Two support plates are fixedly connected to the upper surface of the embedded fence, and LED direct lighting lamps are fixedly installed on the bottom surfaces of the two support plates. A leakage current switch is fixedly installed on the outer surface of the embedded fence. A ventilation component is provided inside the bored pile well. Two hanging rings are fixedly connected to the outer surface of the embedded fence, and fall arresters are fitted on the outer surfaces of the two hanging rings.

[0007] In a further embodiment, the ventilation component includes a ventilation pipe, the top end of which is fixedly connected to a ventilation hood, a ventilation fan is fixedly installed on the inner wall of the ventilation hood, and a ventilation mesh plate is threadedly connected to the inner ring of the ventilation hood.

[0008] In a further embodiment, a fixing block is fixedly connected to the outer surface of the ventilation pipe, and one side of the fixing block is fixedly connected to one side of the embedded fence.

[0009] In a further embodiment, the bottom surface of the embedded fence is fixedly connected to two first fence legs, and the bottom surface of the embedded fence is fixedly connected to two second fence legs. One side of each of the two first fence legs and one side of each of the two second fence legs are in contact with the inner wall of the borehole. The outer surface of each of the two first fence legs has two first fixing holes, and the outer surface of each of the two second fence legs has two second fixing holes.

[0010] In a further embodiment, the height of the embedded fence is 1200mm, and the bottom ends of the two first fence legs and the bottom ends of the second fence legs are embedded 200mm into the wellhead of the borehole.

[0011] In a further embodiment, the outer surface of the embedded fence is hinged with two embedded gates by a pin, and the front of each of the two embedded gates is provided with anti-slip pull holes.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device, with its two first and two second fence legs embedded and fixed at the bottom of the bored pile well, ensures the stability of the embedded fence and effectively prevents personnel from accidentally falling. Simultaneously, the hanging rings on the surface of the embedded fence, in conjunction with the fall arrestor, provide reliable fall protection for construction workers going up and down the well. The fall arrestor can brake instantly in the event of a fall. Compared to traditional unenclosed operations, this reduces the fall risk for both construction and management personnel. Through the coordinated operation of the ventilation fan, ventilation mesh, and ventilation pipes, fresh air is continuously delivered to the bottom of the well, improving air quality inside the bored pile, reducing the risk of poisoning and suffocation, and ensuring safety in confined spaces. Furthermore, the LED direct lighting solves the problem of insufficient lighting inside the bored pile, thereby improving the protective effect of manually excavated bored piles.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figure 1-5In this utility model, a protective device for manually excavated bored piles includes an embedded fence 1, with a bored pile well 8 located below the embedded fence 1. Two support plates 3 are fixedly connected to the upper surface of the embedded fence 1, and LED direct lighting lamps 4 are fixedly installed on the bottom surface of each of the two support plates 3. A leakage current switch 5 is fixedly installed on the outer surface of the embedded fence 1. A ventilation component 2 is provided inside the bored pile well 8. Two hanging rings 6 are fixedly connected to the outer surface of the embedded fence 1, and fall arresters 7 are fitted on the outer surface of each of the two hanging rings 6. Two embedded gates 9 are hinged to the outer surface of the embedded fence 1 by a pin. Anti-slip pull holes 10 are opened on the front of each of the two embedded gates 9. The embedded fence 1 can effectively prevent people from accidentally falling. In addition, the two embedded gates 9 hinged to the surface of the embedded fence 1 can be opened and closed flexibly. When work is paused, the embedded gates 9 can be closed to prevent people from accidentally falling into the bored pile.

[0024] In a further embodiment, the ventilation component 2 includes a ventilation pipe 201, with a ventilation hood 202 fixedly connected to the top end of the ventilation pipe 201. A ventilator 203 is fixedly installed on the inner wall of the ventilation hood 202, and a ventilation mesh plate 204 is threadedly connected to the inner ring of the ventilation hood 202. A fixing block 15 is fixedly connected to the outer surface of the ventilation pipe 201, and one side of the fixing block 15 is fixedly connected to one side of the embedded fence 1. When the ventilator 203 is activated, outside air can be drawn in, filtered by the ventilation mesh plate 204, and then transported to the bottom of the borehole through the ventilation pipe 201 to continuously ventilate the borehole, reducing the risk of poisoning and suffocation for personnel. In addition, the fixing block 15 on the surface of the ventilation pipe 201 ensures that the ventilation pipe 201 is stable in position during ventilation and does not shake or shift, thus affecting the ventilation effect.

[0025] In a further embodiment, the bottom surface of the embedded fence 1 is fixedly connected to two first fence legs 11 and two second fence legs 13. One side of each of the two first fence legs 11 and the two second fence legs 13 are in contact with the inner wall of the borehole 8. Two first fixing holes 12 are opened on the outer surface of each of the two first fence legs 11 and two second fixing holes 14 are opened on the outer surface of each of the two second fence legs 13. The height of the embedded fence 1 is 1200mm. The bottom ends of the two first fence legs 11 and the bottom ends of the two fence legs 13 are embedded into the wellhead of the borehole 8 and further fixed by the first fixing holes 12 and the second fixing holes 14, ensuring that the embedded fence 1 is stable and does not shake, and facilitating its embedding and installation.

[0026] The working principle of this utility model is as follows: First, the bottom ends of the two first fence legs 11 and the two second fence legs 13 are embedded 200mm into the wellhead of the pile well 8, and further fixed by bolts and other connecting parts to prevent the embedded fence 1 from moving left, right, up and down. Then, the embedded fence 1 protects construction workers or managers from falling. Next, the hanging ring 6 on the surface of the embedded fence 1 can provide a reliable hanging point for the fall arrestor 7. When construction workers go up and down the well, they connect the safety belt to the fall arrestor 7. If a fall occurs, the fall arrestor 7 can brake instantly and use its internal mechanical structure to lock the steel wire rope, suspending the personnel near the wellhead.

[0027] Then, when the ventilator 203 in the ventilation component 2 is running, it draws in fresh outside air. After filtering out impurities through the ventilation mesh 204, it is sent to a position 1m from the bottom of the well through the ventilation pipe 201, continuously ventilating the pile hole. Then, the LED direct lighting lamp 4 on the bottom surface of the support plate 3 illuminates the well. At the same time, the leakage circuit breaker 5 installed in the embedded fence 1 is connected to electrical equipment such as submersible pumps. When the electrical equipment such as the submersible pump leaks current and the current reaches 10mA, the leakage circuit breaker 5 quickly cuts off the circuit to prevent construction personnel from being electrocuted. In addition, it is required to check the insulation of electrical equipment regularly every day to further reduce the risk of electric shock.

[0028] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0029] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
