What is an advanced small catheter?

What is grouting pipe - advanced small pipe? Advance small pipe grouting refers to the method of injecting small steel pipes into the surrounding rock above or near the palm fabric before excavation to improve the condition of the surrounding rock and ensure the stability of the palm surface.

Construction method of grouting pipe

In construction engineering, grouting pipes are a very important building material. It is mainly used to inject cement slurry into concrete to enhance its compressive strength and waterproof performance. Next, we will provide a detailed introduction to the construction method of grouting pipes.

Three ways to connect acoustic tubes

There are three ways to connect sound measuring tubes: clamp type sound measuring tubes, spiral type sound measuring tubes, and sleeve type sound measuring tubes.

How to correct the testing accuracy of the bending sound velocity of a sonic tube?

The parallelism of acoustic tubes has a significant impact on the accuracy of sound velocity testing. However, in fact, during the construction process of concrete cast-in-place piles, it is very easy for acoustic pipes to bend and twist, leading to significant deflection.
