Is the wrinkle in the membrane structure of the sewage pool more affected?

The folds of the membrane surface of the membrane structure of the sewage pool can be divided into two types:

1. Defects in the production process of the film, improper heat sealing or improper folding of the packaging are called material folds.

2. The loss of tension on the membrane surface in one direction leads to the relaxation of the membrane, which is called structural folding.

Structural folds are temporary and disappear with re-tension on the membrane surface, while material folds are permanent.

The influence of the folds of the membrane structure of the sewage pool is not only reflected in the visual effect, but also the impact on the structural performance cannot be ignored. The appearance of folds will lead to a redistribution of the pretension of the membrane surface, so that the stresses in some areas of the membrane surface are lower than the design value, and others are higher than the design value. When the membrane surface stress is lower than the design value, the local stiffness of the structure will be reduced, and it is easy to produce breeze vibration. When the membrane surface stress is higher than the design value, it will lead to a large strain of the membrane, and even local tearing of the membrane structure of the sewage pool.

In addition, folds can also affect the aesthetics and drainage performance of the structure; Therefore, wrinkles in the membrane under normal use (long-term load combinations) should be avoided as much as possible.

Affects the visuals. This is easy to understand, so I won't repeat it.

Affects the performance of the structure. The wrinkles of the material will make the stress values in different areas inconsistent with the design values, which will seriously lead to local tears of the reverse tension membrane structure of the sewage pool.

Drainage performance. The folds will affect the drainage performance of part of the membrane surface, and the specific impact depends on the fold area.

The membrane structure of the sewage tank is a new method for treating the waste gas of the sewage tankThis method is not only novel in structure, but also beautiful in shape, easy to install and maintain, and gives full play to the advantages of membrane structure building.

The anti-hanging membrane structure is mainly a steel structure, and the membrane is reverse-hoisted in the form of deodorizing the waste gas of the sewage pool. As a new type of sewage pool exhaust gas deodorization method, the anti-hanging membrane structure has great advantages in membrane performance, structural installation and construction.

Advantages of the covered membrane structure of the sewage tank:

1. The landscape effect is very good.

It can give full play to the imagination of the architect, and the curvature of the membrane structure is difficult to achieve in other buildings, which can fully reflect the natural beauty, artistic beauty, and technical beauty, and is very compatible with the surrounding architectural environment, and is not limited to the small geographical location and difficult place to display the space.

2. Fast processing, manufacturing, construction and installation.

The construction of membrane structure is much faster than that of normal steel structure, and the construction site requirements are not high.

3. Strong anti-corrosion effect.

Due to the particularity of the membrane structure building structure, the steel frame can be erected outside, and only the membrane part is in contact with the primary sedimentation tank, which basically solves the corrosion problem, and there is no need to consider the maintenance problem in the future.

Anti-hanging film is a sewage pool capping method, which is a sewage pool capping method that replaces FRP, sunlight board, color steel and other cover plates with fluorocarbon fiber membrane.

The membrane structure of the sewage pool is often said to be covered with a sealed cover on the sewage pool, and it is called the membrane structure of the sewage pool because it uses a new membrane structure process.

The surface of the membrane used for the sealing of the anti-hanging film of the sewage pool has an anti-fouling coating, and the surface is not easy to be contaminated with dirt and dust, and it can be kept clean for a long time only by the washing of rainwater. The installation is very convenient, which reduces the occupation of the site, especially in the old pool closure and renovation project, the membrane structure can be hoisted as a whole, which does not affect the operation of the equipment inside the pool.

Precautions for the structure of the sewage pool membrane

Heavy objects should not be stacked on the membrane surface for a long time. Although the membrane structure of the sewage pool can bear the weight of people walking on it, stacking heavy objects on it for a long time will destroy the local load capacity of the membrane surface, and in bad weather, it is more likely to accumulate water and snow, and even the risk of being torn.

Do not scrape the surface of the film with a sharp blade or sharp object. The material used on the surface of the membrane structure of the sewage pool is a dense and impermeable weaving material, and the accidental use of sharp blades or sharp objects to scrape the membrane surface will damage the membrane surface, resulting in the aging of the intermediate fabric layer and affecting the service life of the overall structure.

The membrane structure of the sewage pool refers to the membrane structure covered on the sewage tank, which is used to seal the tank body and collect waste odorous gases, which is also often called: gas collection hood.
