Some advantages of square inspection hatches

To effectively curb the spread of the epidemic, travelers leaving Changzhou must carry a negative nucleic acid test report issued within 48 hours. Security personnel have installed barriers and sunshades at the station entrance, posted epidemic‑prevention signs at one‑meter intervals to remind passengers to maintain social distancing while entering and waiting, and, in protective suits, work alongside station staff to verify passengers’ nucleic acid test results.

At the Jiezhou epidemic‑prevention checkpoint on the Yuncheng Expressway, staff on duty are conducting routine checks on a vehicle entering Yancheng from another province. They inspected on-site the procedures for scanning and verifying health codes, conducting arrival‑time testing, and arranging transport for travelers, while offering words of encouragement to those holding their posts. They urged everyone to strengthen personal protection, schedule shifts scientifically, and bolster logistical support, ensuring that all personnel remain fully engaged in epidemic control and help build a robust barrier at transportation checkpoints. It is essential to rigorously implement all control measures at these checkpoints, balancing epidemic prevention with efforts to maintain smooth traffic flow. Tailoring services to the actual circumstances of people and vehicles, they should provide thoughtful, human‑centered assistance, reflecting a commitment to serving the public in every detail.

To ensure all efforts are fully in place, Zhangdian District, in accordance with overarching epidemic prevention and control requirements, has implemented a stringent screening regime at key transportation checkpoints—including highway interchanges and railway stations—on all incoming personnel and vehicles, thereby strengthening epidemic prevention measures and safeguarding the health and lives of the public.

To fortify our county’s defenses against the epidemic, we have strengthened management at traffic checkpoints and established temporary Party branches at each of the 10 checkpoints and inspection stations across the county, led by the public security authorities. These branches fully leverage the exemplary role of Party members and cadres, who are on the front lines, rigorously guarding against the spread of the virus. At key checkpoints such as the eastern highway entrance and the Xiahui Inspection Station, we have deployed additional militia and reserve personnel to better manage vehicle and pedestrian flows, effectively preventing traffic congestion and large gatherings. In addition, one ambulance has been assigned to each location to ensure readiness for emergencies. Reporter:

At the traffic checkpoint inspection stations, the supervision team conducted a detailed inquiry into vehicle and personnel registration, temperature screening, inbound traffic volume, and any existing challenges. The team emphasized that all relevant units must earnestly implement the decisions and arrangements of Party committees at all levels on epidemic prevention and control, demonstrate a strong sense of responsibility, and resolutely ensure the effective execution of all preventive measures. They also reminded frontline staff that, with the recent sharp drop in temperatures, it is essential to take adequate precautions against the cold.

It should be noted that the removal of epidemic prevention checkpoints at all transportation hubs does not signify any relaxation of COVID‑19 control measures. Local authorities must continue to implement, in a scientifically sound manner, all routine epidemic prevention and control measures.

Traffic checkpoints are the frontline of epidemic prevention and control. Chu Xianghao visited, in succession, the Ruicheng East and Shengtian Lake exits of the Yunbao Expressway, as well as the Pinglu Yellow River Bridge checkpoint, where he toured the temporary Party branch and the staff rest area, and conducted an on-site inspection of the standardized construction of these traffic checkpoints.

Deputy Director:

On the 13th, the deputy secretary and county magistrate conducted on-site inspections and oversight of epidemic prevention and control at key locations, including several schools, traffic checkpoints, nursing homes, and detention centers. County leaders accompanied him during the inspections, with principal officials from the Office of Epidemic Prevention and Control, Qingquan Town, the health commission, the education bureau, and other relevant departments in attendance.

Cleaning of pipelines at varying depths and diameters, including sewer pipes, open channels, and underground conduits. 1. Use a slurry pump to discharge sewage from the inspection chamber down to the bottom sediment. For pipelines requiring desludging, divide the section into segments based on pipe diameter and length, installing one segment between two inspection chambers of identical diameter. 2. Employ a high-pressure water truck to inject water into each segment between the two inspection chambers, using a jetting tool to agitate and dilute the sludge within the chamber and the sewer line. Manually and mechanically continue stirring the sludge until it is fully diluted into a watery consistency. 3. Use a vacuum‑suction truck to remove the slurry from the inspection chamber. Apply high-pressure water to loosen the sediment at the chamber floor, then further dilute the sludge in both chambers before completing the suction process. 4. Install sealing plugs: starting from the top, seal the inlet of the uppermost segment within the chamber. Subsequently block the outlets of downstream inspection chambers and other connected pipelines, leaving only the designated inlet and outlet for this particular pipeline.

Not long ago, a warning was issued regarding irregularities in nucleic acid testing at certain highway checkpoints in Zhangjiakou, Hebei; Hefei and Anqing, Anhui; and Shangluo, Shaanxi, explicitly emphasizing the need to resolutely prevent unauthorized closures of expressways and ordinary roads, as well as the arbitrary establishment of epidemic‑prevention checkpoints.

According to statistics, as of March 23, more than 400 winter coats have been distributed to frontline personnel at 16 highway checkpoint stations, including the Louta and Linpu toll plazas.

On the 7th, multiple people reported that防疫 checkpoints at several expressway entrances in Shijiazhuang have changed: on‑site nucleic acid testing has been canceled, and vehicles with Hebei A license plates can now pass through directly without stopping for inspection.

On the 13th, the county magistrate conducted on-site inspections at transportation checkpoints, including Zhen’an Railway Station and Wangjiaping Expressway, to oversee epidemic prevention and control efforts. Members of the Standing Committee and the deputy county magistrates, along with members of the Standing Committee who also serve as department heads, accompanied the inspection.

On the 7th, multiple netizens reported that epidemic‑prevention checkpoints at several expressway entrances in Shijiazhuang have changed: on‑arrival nucleic acid testing has been canceled, and vehicles with Hebei A license plates can now pass through without stopping for inspection.

Since the onset of epidemic prevention and control, Xiangxi traffic police have remained on duty around the clock at checkpoints along expressways and national and provincial highways throughout the prefecture. Working in close coordination with epidemic‑control personnel, they conduct rigorous inspections of all incoming and outgoing vehicles and individuals, verifying origins, recording identities, and taking temperature readings. They also turn back high‑risk vehicles and direct and guide traffic within their jurisdiction, resolutely cutting off pathways for the spread of the virus.

On the 10th, at the epidemic prevention checkpoint in Song’an Village along Sanxian Avenue in Jiexiu City, staff members meticulously and patiently conducted health screenings on passing vehicles and their occupants in accordance with established procedures. This checkpoint serves as a critical gateway; local authorities have actively coordinated rescue teams and streamlined and standardized traffic‑control protocols at entry points, ensuring rigorous oversight of all incoming and outgoing traffic.

With this convenient inspection well, design and construction can be optimized, even though preventing other quality issues can sometimes be quite challenging. Our square concrete inspection wells vary in price from one supplier to another; here we’ve provided an overview of pricing for square concrete inspection wells in Chongqing. Pricing is generally divided into several key categories: elevator‑type inspection wells, elevator shaft inspection wells, considerations for floor‑level slope during construction, stability‑related inspection wells, fire‑protection wells, reclaimed‑water wells, layout of vertical shaft openings, and cable‑management inspection wells—along with the preparatory steps required before construction begins. Construction requirements differ for each component, and the methods employed also vary accordingly.

Traffic checkpoints are the frontline of epidemic prevention and control, and it is imperative to rigorously safeguard the gateway against imported cases. In Shijiazhuang, public security, traffic management, health, and other relevant departments at all entry and exit points have worked in close cooperation, coordinated their efforts, and pooled their resources. During the holiday period, police officers, auxiliary police, and public health personnel stationed at inspection and control posts across the city remained steadfastly on duty, coordinating seamlessly to maintain strict oversight at every checkpoint, thereby firmly fortifying the city’s defenses against the pandemic and ensuring its safety. At the north side of the inspection and control post at the west end of Yuhua Road, a nucleic acid sampling area and an information‑supplementing zone have been set up, where health workers are conducting nucleic acid tests and updating personal information in an orderly manner. A dual‑card system—Cards A and B—is in place at all entry points into the city. Travelers whose itinerary records only Shijiazhuang are eligible for fast‑track passage with Card A; those with travel history outside the city must undergo on‑arrival nucleic acid testing and complete information registration on the north side. Only after these steps are completed will they be issued a Card B pass, allowing them to proceed.

(Ganzhou Media Reporter) On the evening of July 18, while conducting a supervisory inspection of epidemic prevention and control at traffic checkpoints, the Party Secretary emphasized that these checkpoints are critical gateways. He stressed the need to maintain a clear understanding of the current severe epidemic situation, uphold a strong sense of responsibility, remain constantly on high alert, and rigorously, practically, and meticulously implement all prevention and control measures. By tightening and reinforcing the defense line, we must resolutely block all pathways for the importation of the virus, sustainably consolidate the hard-won achievements in epidemic control, and do everything possible to safeguard the lives and health of the people.

On the 1st, the vice chairman and the secretary conducted on-site inspections and oversight of epidemic prevention and control measures at designated checkpoints in locked-down communities, controlled‑area neighborhoods, regular residential areas, quarantine hotels, and traffic control points. They heard briefings on the situation at each community, at the traffic checkpoints, and at the duty stations. They also received reports from the dedicated task force stationed at the hotels regarding the number of quarantined individuals, epidemic prevention and control protocols, staffing arrangements, and logistical support, and carefully reviewed relevant records and emergency response plans. District leaders participated in these inspection and supervision activities.

As at the Beiqian Expressway checkpoint, to ensure that all travelers arriving from or returning from epidemic‑affected areas—both within and outside the province—are promptly tested upon arrival, each county (district, city) in our city has established an adequate number of nucleic acid testing stations at all checkpoint locations. These sites have been strategically positioned and laid out, with sufficient staffing—including sampling personnel, testing technicians, and logistical support staff—to prevent large‑scale, prolonged gatherings and delays. This approach guarantees swift sampling, timely testing, and accurate results, while also ensuring that test outcomes are promptly uploaded to the designated information platform.
