Aluminum Flood Protection Baffle Standing on the Tip of the Tuyere

[China Aluminum Network] Now that the country is suffering from floods caused by torrential rains, a group of flood prevention walls called Germany's NB has triggered a huge wave of discussion on the Internet.

The specific content is this, this flood control baffle is called Spundwand in Germany. It is usually pressed by 15cm thick aluminum alloy to grow 2M square-shaped aluminum beams.

Compared to our human wall flood panels, do you think that there is snack acid?

Slow! ! ! The tears will be withdrawn first. Look at the following.

Huh? Compared to NB's anti-flood artifact also "pit father"?

In fact, the amount of engineering for this flood control baffle determines that it cannot be a temporary flood control project. The hardness and bearing weight of aluminum also determine this baffle performance. On the front, it can only be used for rivers with small water volumes and low flow rates. Similar things have already been put into use in some parts of northern China. Secondly, this flood protection wall is used for temporary reinforcement in areas without embankments. In the face of floods, it is simply the arm and arm that is not on the same level as the reinforced concrete embankment.

Say this board, Dahong can not block, then used to do? Since Dahong couldn't stop it, it was still OK. For example:

Flood-proof baffles in underground garages can reduce floods. Made of aluminum alloy sheet, with a thickness of 2mm. The flap consists of a panel and slot posts on both sides. The length of the panel is the width of the entrance and exit. The stainless steel hinge is set in the middle of the panel (can be folded in two to facilitate manual transportation). After that, several stainless steel supports can be opened and closed, and the support points can be set with adjustable devices; the weight design of each flap is not more than 50kg. The height of both sides of the column is about 500mm, and the material is made of 2mm thick stainless steel plate. The bolt locking device is set; the bottom of the baffle, the column and the hinge part are sealed with anti-seepage water.

Little friends, now understand?
