Manufacturing process of composite manhole cover [2023-01-27] With the use of composite manhole covers becoming more and more extensive, the proper installation method can be selected in the whole project construction process to achieve a stronger use effect. In order to better apply, let's take a look at the manufacturing process of composite manhole covers. -
Advantages of high temperature molding process for composite well cover [2023-01-20] The composite well cover is made of polymer composite materials. The internal framework is mainly made of steel bars and is made of high temperature molding. Its high strength can withstand 50%. TWeight. The process of composite manhole cover is high temperature molding and injection molding, and the process of cast iron manhole cover is casting molding. Then, compared with the two kinds of well covers, what is the reason why the high-temperature molding process is more advantageous than the casting process? -
Reasons for low cost of composite well cover [2023-01-13] High temperature and high pressure one-time molding technology is adopted, and the composite well cover has the advantages of high polymerization degree, high density, good impact resistance and tensile strength, good wear resistance, corrosion resistance, no rust, no pollution, no maintenance, etc. Not only that, the composite well cover is also called "green well cover" because of its low manufacturing cost. What is the reason for the low cost? -
Causes of collapse of composite well cover [2023-01-06] The utilization rate of composite manhole covers is getting higher and higher. Do you know the reason for the collapse of composite manhole covers? In the whole installation process of the composite well cover, the overall design boundary of the well cover and the shaft is small, and there is no structural reinforcement and hoisting design of the reinforcement layer. It is unscientific to plan pipeline works on the whole motorway. In urban public transport, manhole covers damaged due to insufficient carrying capacity are used by a large number of overweight vehicles. The bearing capacity of the oil well is small, exceeding the weight and load of the well cover itself, and the foundation settlement is large. The construction of shaft foundation reinforcement works was not standardized, the shaft cover and ground were uneven, the structure was broken, and even the service life of the composite shaft cover was reduced and damaged. The foundation on the well was not installed according to the specifications, and the construction team did not install it according to the regulations. -
What are the reasons for the cracking of the base course of the composite well cover [2022-12-30] In the application of composite manhole covers, many users reported that the base layer at the installation site was always cracked, and it was unclear what caused it. What is the reason for the fracture of the base course of the composite well cover? -
What is the cleaning work of composite well cover [2022-12-23] Now, the application of manhole covers is more and more extensive. As one of the products of well covers, we can often see well covers with nodular cast iron grate. As long as there are sewers, you will see composite well covers. Although the manhole cover is not conspicuous, it plays an important role in it. Let us tell you about the cleaning of the composite manhole cover. -
Disassembly and installation of composite well cover [2022-12-16] The composite manhole cover is made of new polymer composite materials, with steel bars as the main internal skeleton, and is produced through high-temperature molding. The following describes the disassembly and installation of the composite manhole cover, hoping to help you. -
How to improve the structural strength of composite well cover [2022-12-07] The mesh reinforcement is used to strengthen the interior of the composite manhole cover, and the key load-bearing parts are especially strengthened. When the inevitable impact of external force occurs, the pressure can be quickly dispersed to ensure the safety of people and vehicles. So how to improve the structural strength of the composite well cover? Let's take a look. -
How to ensure the quality of composite well cover [2022-12-02] With the continuous development of urban road construction, the use of composite manhole covers has gradually increased, and quality assurance has become a more concerned issue at present. In order to ensure the safety of vehicles and pedestrians, the quality requirements of composite manhole covers are very high. Therefore, the quality of composite manhole covers has become a very important factor in selecting road manhole covers. How to ensure the quality of composite manhole covers? This is for you. -
How to clean the surface of nodular cast iron manhole cover? [2022-11-25] What should be done when cleaning the surface of nodular cast iron manhole cover? After long-term installation, the hand hole made of pig iron nodular cast iron is covered with wind and sun, so there must be dust and air pollutants in the outside world, so the surface looks like dust, scratches and rust. How should we wait and keep clean? -
Advantages of Ductile Iron Grate [2022-11-18] What are the advantages of ductile iron grate? I believe everyone will not be surprised. It can be seen everywhere in our life, big enough to be seen on the road. They can see it in the park, from childhood to property. Careful friends may find that the grate installed there is generally round. Do you know why you like to use round nodular cast iron grate on the road? What are the advantages of round nodular cast iron grate? Let's study together with Xiao Bian. -
What are the technical requirements for the welding of composite manhole cover? [2022-11-11] By using CIIC, raw materials can be accurately put into the production process in order to achieve uninterrupted batching. With the progress and development of China, mechanization and automation are a major trend. However, in our production workshop, many places still need manual operation, because the machine is dead after all. In fact, welding is very important. If the welding is not firm or other problems easily lead to accidents after later installation, we will analyze according to the technical requirements.
