The dam bags produced, installed, and debugged by the company have been rated as excellent projects.

The dam bags produced, installed, and debugged by the company have been rated as excellent projects.

The company mainly produces rubber dam products and can produce various forms of dam bags according to user requirements (book ridge type, gas shield type, wrinkle free type, disturbed pillow type, disturbed slope type). The company has a complete set of advanced production equipment, an annual production capacity of 1 million square meters, and has long-term cooperation agreements with several universities and scientific research units nationwide, thus forming a complete technology development system, Thus, the company has always maintained a leading position in technology within the same industry. The company has now produced and installed over 10000 rubber dams, including over 3000 colored dam bags, which are not only distributed throughout the country, but also exported to countries such as Indonesia, Bangladesh, Iran, Nigeria, Russia, Chile, etc. The dam bags produced, installed, and debugged by the company have been rated as excellent projects.

Precautions for selecting filling media for rubber dam bags

Precautions for selecting filling media for rubber dam bags

Rubber dams, as a new type of water retaining structure, have been widely used in China since the 1990s. The top of the rubber dam can overflow, and the height of the dam can be adjusted according to needs, controlling the upstream water level, and exerting irrigation, flood control, and tide blocking functions. The rubber dam bag adhesive tape is mainly made of high-strength Synthetic fiber as the stress skeleton, with rubber coated inside and outside as the protective layer. The filling medium of the dam bag is mainly water and gas. How to choose dam filling media to achieve safe, reliable, and economically reasonable purposes requires consideration of multiple factors. This article takes a proposed rubber dam as an example to explain the relevant issues that need to be paid attention to when selecting the filling medium for the dam.

In addition to the key factors related to the stability and safety of rubber dams

In addition to the key factors related to the stability and safety of rubber dams

In addition to the key factors related to the stability and safety of rubber dams, the most suitable filling medium should also be determined through overall consideration from the following aspects. Flood season dam collapse: The premise of rubber dam construction is not to affect the flood discharge of the river section during the flood season. During operation, it is required that the rubber dam must collapse during the flood season. Due to different filling media, the control of dam collapse is also different. Water filled rubber dams usually require the equipment to be a power source, and they usually use forced drainage to collapse the dam in order to better meet the flood discharge requirements. However, inflatable rubber dams rely on the water pressure during flood discharge to remove gas from the dam, and generally do not consider backup power sources. Relatively speaking, the electromechanical equipment equipped with inflatable rubber dams will save investment. Water filled rubber dams generally have large wells and require a certain groundwater level to ensure the normal operation of the rubber dam. The existing water filled rubber dams even use urban tap water for dam filling due to water source issues, resulting in increased operating costs. In contrast, inflatable rubber dams effectively avoid similar problems. It should be noted that inflatable rubber dams have high requirements for airtightness, and some inflatable rubber dams constructed in the early stages have such problems, causing safety hazards. With the development of science and technology, the problem of air tightness in previously inflatable rubber dams has been solved, and different forms of filling media can meet the functional requirements of engineering.

What is the difference between water filled rubber dams and inflatable rubber dams

What is the difference between water filled rubber dams and inflatable rubber dams

The filling and discharging time of water filled rubber dams is longer than that of inflatable dams. In terms of cost, there is not much difference between the two types of dams. The operating conditions of rubber dams are similar to those of water gates, but compared to conventional gate dams, they also have the following characteristics:
