[0002] Railways are the main arteries of my country's national economy. Railway lines carry station cars, passenger and freight trains for uninterrupted operation, and have made great contributions to my country's transportation and material transportation. With the continuous expansion of my country's railway transportation network, the number of constructions adjacent to operating railway lines has gradually increased. In order to ensure the construction safety of adjacent operating railway lines, a series of construction management methods for adjacent operating railway lines have been formulated in the prior art. However, in the actual construction process of new or expanded railways, there will still be safety hazards and construction accidents caused by poor construction management of adjacent operating railway lines, inadequate implementation of safety systems, and inadequate post-supervision, which seriously affect railway driving safety. As an important part of the construction of railway operating lines, the safety issues existing in the construction of adjacent operating lines must be taken seriously.

[0003] Therefore, it is an urgent problem for technical personnel in this field to propose an anti-intrusion safety protection system for the construction of piers and abutments near operating lines, further monitor the safety of the construction of adjacent railway operating lines, and vigorously reduce or eliminate all safety hazards during construction.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0033] Reference Figure 1 As shown, the present invention discloses an anti-intrusion safety protection system for the construction of near-operating line caps and pier bodies, including: a detection terminal, a cloud security service platform and an alarm device;

[0034] A detection terminal is connected to the input terminal of the cloud security service platform, and is used to detect the construction environment information of the operating line and send the detection information to the cloud security service platform;

[0035] The cloud security service platform is connected to the input end of the alarm device, and is used to receive the detection information sent by the detection terminal, process the detection information, and send the processing result to the alarm device;

[0036] The alarm device is used to determine the alarm level reached by the processing result, and to warn specific personnel so that the specific personnel can take corresponding safety measures.

[0037] Furthermore, detection terminals are arranged at monitoring points on both sides of the operating line, and a total of 4 detection terminals are arranged at monitoring points with excavation depth <5m, and the 4 detection terminals are located at the center point of each side of the steel sheet pile cofferdam;

[0038] A total of 8 detection terminals are arranged at the monitoring point with excavation depth ≥5m, and the 8 detection terminals are located at the center and intersection of each side of the steel sheet pile cofferdam;

[0039] The distance between monitoring points on each side of the operating line shall not exceed 10 meters, and the number of monitoring points shall not be less than 3.

[0040] Furthermore, the detection terminal includes a video monitoring module, an anti-intrusion monitoring module, an identification module, and a security monitoring module which are connected in sequence.

[0041] Furthermore, a video monitoring module is used to monitor the surrounding information of the business line in real time through a camera;

[0042] The anti-intrusion monitoring module is used to detect whether there are people approaching high-risk areas and whether there are dangerous behaviors;

[0043] A recognition module is used to authenticate the target face image and the helmet;

[0044] The safety monitoring module is used to monitor whether construction workers are not wearing reflective clothing, whether warning signs are placed, and whether construction tools are insulated.

[0045] Furthermore, the cloud security service platform adopts the DataEase data visualization and analysis platform.

[0046] Further, the alarm device includes an indicator light module and a communication module;

[0047] The indicator light module includes green light, blue light, yellow light and red light;

[0048] The communication module uses a LoRa module or a NB-IoT module.

[0049] Furthermore, the operating condition hazard assessment method is used to determine the treatment results. The formula is: D=LEC, where D is the hazard analysis, L is the possibility of an accident, E is the frequency of exposure to a hazardous environment, and C is the consequence of an accident.

[0050] Furthermore, when the D value is less than 70, it is Level I risk and the green light flashes; when the D value is between 70 and 160, it is Level II risk and the blue light flashes; when the D value is between 160 and 320, it is Level III risk and the yellow light flashes; when the D value is greater than 320, it is Level IV risk and the red light flashes.

[0051] In a specific embodiment, this operating line involves the reconstruction of the existing line of the Beijing-Kowloon Railway Lushan-Nanchang section and the Changjiu Intercity Railway, which places extremely high requirements on the protection of existing line equipment. At the same time, the existing railway roadbed slope protection facilities and temporary track blockade measures should be removed before filling the embankment to widen the road. Coordination is difficult and the construction safety risk is high. According to the on-site survey, the construction of the existing line in this section is mainly designed to be close to the existing line on one side, construction outside the operating line, construction close to the operating line (roadbed), and existing line construction on both sides. During the construction process, a cable wind rope oblique drilling rig was set up, and the ground anchor was fixed with 2.5-meter steel sheet piles with an anchoring depth of 2m.

[0052] The construction of the foundation of this section is close to the existing railways such as Changjiu Intercity Railway, Beijing-Kowloon Down Line, Beijing-Kowloon Down Link Line, Beijing-Kowloon Up Line, and Wujiu Southwest Link Line. According to the preliminary survey, the distance between the foundation protection pile and the existing track is 3.77 to 29.64m. During the construction, the order of protection first and then construction is adopted. Steel sheet piles are mainly used for protection, and some sections are protected by cast-in-place piles. The steel sheet piles are protected by Larsen IV steel sheet piles, the enclosure adopts double-jointed I40a or triple-jointed I40a, and the internal support adopts 630×8mm steel pipe piles. The protection piles are less than 6m from the center of the operating line track, and the rest are bored piles.

[0053] For foundation caps with good geology and shallow burial depth, the excavation of the foundation pit adopts slope reduction measures with a slope of 1:0.5. If it is found that this slope cannot meet the requirements during the construction process, the slope can be slowed down or woven bags filled with soil can be piled up to increase the stability of the foundation pit slope. The base size after excavation is ≥ the size of the foundation cap structure + 0.5 meters. It is strictly forbidden to touch the pile foundation with force during the excavation process to avoid damage to the pile foundation.

[0054] like Figure 2 As shown in the figure, the detection terminals are arranged at the monitoring points on both sides of the operating line. A total of 4 detection terminals are arranged at the monitoring points with excavation depth <5m. The 4 detection terminals are located at the center point of each side of the steel sheet pile cofferdam. Figure 3 As shown in the figure, a total of 8 detection terminals are deployed at the monitoring points with excavation depth ≥ 5m, and the 8 detection terminals are located at the center and intersection of each side of the steel sheet pile cofferdam; the distance between the monitoring points on each side of the operating line is no more than 10 meters, and the number of monitoring points is no less than 3. The detection terminal is used to detect the construction environment information of the operating line. The cloud security service platform receives the detection information sent by the detection terminal, processes the detection information, and the alarm device determines the alarm level reached by the processing result, and alarms specific personnel, who take corresponding safety measures.

[0055] The operating condition hazard assessment method is used to judge the treatment results. The operating condition hazard assessment method uses the product of three factors related to the system hazard to evaluate the size of the system's personnel casualty risk. The formula is: D = LEC, where D is the hazard analysis (Table 4), L is the possibility of an accident (Table 1), E is the frequency of exposure to a hazardous environment (Table 2), and C is the consequence of an accident (Table 3).

[0056] When the D value is less than 70, it is Level I risk and the green light flashes; when the D value is between 70 and 160, it is Level II risk and the blue light flashes; when the D value is between 160 and 320, it is Level III risk and the yellow light flashes; when the D value is greater than 320, it is Level IV risk and the red light flashes.

[0065] In addition, all workers entering the construction site must undergo safety training, and special workers must hold certificates before taking up their posts; the person in charge of the construction must achieve "four in place", namely, personnel in place, positions in place, responsibilities in place, and professional level in place. Non-construction personnel are prohibited from entering the installation site, and full-time safety officers are arranged to conduct daily inspections. There must be a safety officer on duty every day. All construction workers must wear safety helmets before entering the construction site. When working at heights, you must wear a safety belt, wear non-slip shoes, and the tools should be placed in the tool bag. When working at height, preventive isolation measures must be taken at the lower part, and construction workers are strictly prohibited from passing below. Flammable and explosive items must not be stacked in the work area. Existing line safety guards should strengthen patrol work along the line to ensure the personal safety of construction workers, driving personnel and equipment operators. Construction workers carry out construction in designated areas, and it is strictly forbidden for personnel and machinery to cross the construction protection fence to work.

Various modifications to these embodiments will be apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention will not be limited to the embodiments shown herein, but rather to the widest scope consistent with the principles and novel features disclosed herein.
