[0002] As buildings become more and more magnificent and taller, higher requirements are placed on the bearing capacity of single cast-in-place piles. Post-grouting technology is often used in engineering to improve the bearing capacity of pile foundations. Since the grouting slurry needs to be mixed on site, vertical grouting silos are often set up on site to store cement and other raw materials. During tunnel construction, grouting is generally required to achieve the effect of blocking water outlets. Grouting water blocking is to configure and mix materials with filling and bonding properties and press them into the cracks.
