Prevention of Landslide and Reinforcement of Post - disaster Buildings

Aug. 31, 2017

August 28, landslides occurred in the Zhangjiawan town, Nayong country, Bijie city, Guizhou province. According to the preliminary verification, now it has caused two people dead, four people injured and 25 people lost. Guizhou province has started the level II emergency plan of geological disaster. At present they are doing rescue and relief work in a good order. We all know that the debris flow caused by the landslide is a very serious natural disaster. The mountainous landslides in Shenzhen in 2015 also caused dozens of deaths. And many buildings were covered. In the face of this natural disaster, we should do the pre-disaster prevention and post-disaster relief. Mankate has decades of experience in building reinforcement, and today we talk about how to deal with debris flow disaster.

 

First of all, before the disaster, we should discover the slopes with the possibilities of risks in advance. In general, the mountain slopes need to be excavated the mountain foot as a result of the construction of highways and houses near the mountains. So it often happens slides due to the loss of support of the lower parts of the slopes. Therefore, we must use certain technical measures to improve the mechanical strength of the rock and soil of slopes. We should enhance the skid resistance and reduce the sliding force. The common used measures include slope cutting and slope manual reinforcement. We can lay prestressed anchors or anchor cables to reinforce the rock slopes with cracks or weak structural surfaces. For the cracks, seams, holes, we can use carbon fiber cloth, repair glue, filling glue and other methods to strengthen to prevent further expansion of cracks.

 

After the disaster, we have to reinforce the houses stuck by the debris flow. The walls of the houses stuck by the debris flow will incline. So we had better re-support the houses by using the method of planting steel bars. The technology of planting steel bars is also known as steel rooting technology. That is, drilling on the original concrete structure, injecting structural adhesive, rotating the new steel bar into the holes. This technology is widely used in design changes, increasing the beam, column, cantilever beam, plate and other reinforcement and change works. The process of planting steel bars requires using the high quality anchorage glue. Otherwise the best steel bar is also of no help. Mankate anchorage adhesive has strong anchoring force. It is suitable for all substrates. So it is the best choice in the post-disaster reconstruction. Besides it is fast-installation, condensed-quickly and can save the construction time. We can look at some projects of Mankate anchorage adhesive in the previous reinforcement.

We can see that Mankate anchorage adhesive still can work properly under the damp and severe environment and underwater. So in some areas where there are many torrential floods and debris flow. We are badly in need of such moisture-proof and anti-corrosion products to help us rebuild our homes. Therefore, I hope the relevant departments can pay attention to that, no matter before the disaster or after the disaster, we need to attach much importance to the reinforcement projects.
