How to handle the difficulty of Zhuhai foundation pit construction? Huma gives the answer online!

During the construction of a foundation pit in Zhuhai, serious groundwater leakage and high sediment content greatly increased the difficulty of construction and affected the efficiency of the project. But our company's cable duct blocker effectively solves this problem.

Hebei 110kV Substation Incoming Line Waterproof Sealing Project

There were many thunderstorms and typhoons in August, and a rainstorm came down, and the rainwater flowed along the cable duct to the cable trench. Even though the hole was originally blocked with cement, because the water pressure was too high, the cement was washed away, resulting in serious water accumulation in the cable trench. Looking at the pool in the trench, do you also face this problem? Last week, our company's technicians visited the incoming basement of a 110 kV substation of a power supply company in Hebei Province. Due to the continuous rainstorm weather, the water depth in the basement was as high as 2 meters. Some of the holes originally sealed with cement also fell off, and some are constantly flowing out. In order to meet the requirements of the leadership of the power company, an inflatable cable duct sealing device was installed to completely seal the cable duct opening, The construction personnel first need to clean the accumulated water in the ditch. Due to the depth of the water, it took them an hour to pump it out completely. However, the drainage system is not perfect, and the discharged water flows towards nearby farmland, which can easily cause harm to crops. In this situation, we strongly recommend using an inflatable cable duct sealing device. It can not only achieve a completely waterproof state, but also be used for both empty and threaded pipes. It is easy to install, disassemble, and maintain afterwards. During the installation process, our company provided explanations to the construction personnel. During the subsequent installation process, the construction personnel directly called for simple and convenient express delivery. After mixing with cement and waterproof agent, the traditional sealing method has obvious drawbacks. The disadvantage of traditional sealing is that the material and pipeline may crack due to thermal expansion and contraction, resulting in the loss of waterproof function. In addition, as long as the cable is repaired by splicing, it will damage the pipeline sealing material and require re sealing. It is also inconvenient for future cable expansion, as the pipeline has already been fixed, which may damage the entire pipeline.

Sealing of 110KV Hengban Line Cable Bushing at Jinjiang Airport

The cable sleeve for the connection line of Jinjiang Airport and the 110KV Hengban Line is sealed with corrugated sleeves, which are difficult to completely fill without gaps using mechanical sealing products. However, the use of inflatable cable pipeline sealers can effectively seal the pipeline. Inflatable cable duct sealer is a flexible duct sealing device with strong compatibility with pipelines. Whether it is corrugated or deformed, it can adapt well to pipelines and perform seamless filling.

On site teaching of sealing for the Yunxiao Civil Low Voltage Reconstruction Project

The civil low-voltage renovation project of Zhangzhou Yunxiao Power Supply Company has a heavy workload. In order to complete the cable hole sealing renovation project as soon as possible, each construction team has worked overtime, and our company has also sent professional technical personnel to provide on-site teaching guidance. For various special situations of reserved pipelines and cable threading pipelines, different sealing devices are used for sealing. The following is a representative image taken by the company's technical personnel on site before sealing. The reserved pipeline left by the construction on the left and a cable threading pipeline on the right are both cases where we need to seal these holes. The reasons for sealing are as follows: Firstly, for reserved pipelines, sealing the opening can ensure that mud, rainwater, and other substances leak into the well through the pipeline, causing water accumulation and other problems, and causing trouble in subsequent underground well maintenance such as pumping. Blocking the reserved pipeline can maintain a dry environment inside the well, while also preventing small animals such as rats and ants from wandering around in the interconnected pipeline, leaving corpses that can cause blockage to the pipeline. It is appropriate to use the hollow pipeline sealing plug as a sealing device, which is specifically designed for sealing empty pipes. It is not only aesthetically pleasing, but also reusable and has a high cost-effectiveness. 2、 For cable through wall pipelines, it is also necessary to block them. 1. It can avoid the adverse effects of accumulated water, sediment, mice, etc. on the pipeline environment, providing a relatively clean and dry working environment for manual underground operations or underground pipeline construction; 2. It can achieve waterproof, rat proof, and anti-theft effects, better protect cables from external factors, and reduce cable accident rates; 3. After segmented sealing of the pipeline, the problem of pipeline flow is avoided, which can greatly reduce the trouble and time of manual well pumping and dredging, and improve operational efficiency.

Inflatable cable duct blocking device went to Xinjiang Oilfield Company Power Supply Company

Recently, our technicians received from the Xinjiang Oilfield Company power supply company call, they are troubled, due to the low temperature weather in the Xinjiang region, the cable wells are located in the green belt underneath the basic watering twice a day, and the cable pipe underground cable pipe for the PVC pipe, the green belt of the water seepage into it, but due to the design of the drainage channels are not designed, but also not easy to evaporate, so the water accumulated after a certain period of time water level will be more than the cable pipe Height, and because the pipeline is connected, the two sides of the power underground wells will share the water level, and the cable will always be in the water immersion, the operation of the cable is very dangerous. When one of the underground wells is opened for cable maintenance management, the water in the underground well must be extracted first, which is very troublesome. Therefore, in the case of not blocking the power underground well maintenance costs consumed will be incalculable, once the repair situation, to do with the time to race is the difficulty of the repair work to increase. In response to this situation, my company's technical staff to the Xinjiang Oilfield Company power supply company recommended a Hengma brand inflatable cable pipe blocking device, and personally go to the Xinjiang Oilfield Power Supply Company to observe the leakage of cable pipelines, and then mounted on this product to block the cable pipeline, to avoid water, silt and other damage to the cable and pipeline safety. Specifically, you can refer to the following pictures: inflatable cable pipe sealing device is a new generation of pipe blocking technology, the use of gas expansion sealing principle, combined with the current pipeline and cable blocking needs and design and development of new blocking devices, compared with the traditional blocking products such as blocking mud, cement, wood plugs, etc., the inflatable cable pipeline sealing device has the following obvious advantages: 1, the construction is convenient and easy to use: equipped with sufficient gas can be. 2, reusable: the unique gas nozzle design is convenient for maintenance and replenishment. 3, stable performance: soft metal high-density polymer materials can adapt to a variety of pipeline environments. 4, longer service life: helium diffusion experiments have proved that the theoretical use of 20 years. The product has a national patent, protected by the national intellectual property rights, and through a number of overseas experiments, the performance of all the national standards, product performance stability and quality assurance.

Jiangsu Lianyungang substation 110kv cable trench waterproof sealing case

Let the power company a headache: cable trench waterproofing blocking difficulties Jiangsu Lianyungang substation 110kv, because the cable trench waterproofing blocking is not in place, covet the convenience of cement for a rudimentary blocking state, because the cable in constant operation of the thermal expansion and contraction, slowly and the cement to form a circle of seams, the wall of the pipe wall for a long time to suffer from soil water, groundwater, rainwater, etc., erosion, cover joints, wall and deformation joints, etc., there are many water seepage and leakage, so that often in a wet environment, and even many parts of the ditch to accumulate soil. Walls and deformation joints appear in many places seepage and leakage, so that the cable trench is often in a humid environment, and even many parts of the trench are accumulated soil. The normal operation of the transmission of electricity causes great safety hazards, so it is necessary to plug the leakage and repair treatment.
