According to the manufacturer's test report, the test index is determined by the construction unit, and many indicators! Zhejiang plastic drainage board manufacturers answer!

Plastic drainage board is a very common building material item in our engineering building materials, and it can often be seen on some construction sites, plastic drainage board is also called plastic drainage belt, there are many shapes and specifications, and it is very useful in soft soil foundation engineering, such as highways, railways, airports and ports and other occasions can be used.

After having a plastic drainage board, the construction of the project will be very convenient, and the plastic drainage pipe Xiaozhi replaces the function of bag sand to a large extent, and it is economical, and has great plasticity in terms of use and use. So, is the effect of plastic drainage board good, and what are the models?

Effect of the use of plastic drainage boards.

First of all, the water filtration performance of the plastic drainage board is good, which can keep the drainage smooth, and the drainage effect is also better than other materials, and the effect can be guaranteed by the plastic drainage board. Secondly, the application performance and plasticity of the plastic drainage board can be strong, and can change according to the changes in the actual construction situation, and the strength and ductility are very good, and the drainage performance of the practical one will not be affected by external reasons. The cross-sectional area of the drainage board is small, so it will not be troubled and affected by the construction of the foundation.

When some foundations are relatively weak, plug-in board construction is also an advantage of plastic drainage board, so, it can be seen from the above that plastic drainage board is not only more convenient to use in terms of performance, but also has strong applicability of plastic drainage board.

The model and condition of the plastic drainage board.

There are generally four models of plastic drainage boards, namely SPB-A, SPB-B, SPB-C, SPB-D, these models are the most common models of plastic drainage boards, let's take a look at them one by one, these models of plastic drainage boards are suitable for use in what circumstances.

The different types of drainage boards of these plastic drainage boards are used for vertical drainage, the difference is that the use of different types of plastic drainage boards in the depth of the suitable soft soil foundation is different, firstly, the use of SPB-A is the use of vertical drainage on the soft soil foundation within the depth of 15 meters, the depth of SPB-B is suitable for the use of between 15-25 meters, the use depth of SPB-C is between 25-25 meters, and the use depth of the last SPB-D is 35 meters and above.

Plastic drainage boards are now widely used on construction sites, and there are a variety of models to adapt to different soil types, and the use of plastic drainage boards is also a sign of progress in engineering materials.

At present, the standards that can be used for the detection methods involving the spine grinding water belt (plate) are mainly the following:

JTS 206-1-2009 Technical specification for the application of plastic drainage boards for water transportation.

JT T 521-2004 Highway Engineering Geosynthetics Plastic drainage board (belt) In these two standards, the testing requirements for thickness are the same, and they are all measured by calipers. It's just that one is simpler, and the other is more detailed. Now the clipping will be more detailed as follows:

Hello, it can be measured with vernier calipers, and the accuracy will be high.

SPB-A type plastic drainage board Vertical drainage of soft soil foundation within 15 meters SPB-B type plastic drainage board Vertical drainage of soft soil foundation within 15 25 meters Vertical drainage of soft soil foundation within 15 25 meters SPB-D type plastic drainage board Vertical drainage of soft soil foundation within 25 35 meters Vertical drainage of soft soil foundation with a depth of more than 35 meters.
