There has been an accident in the raw material warehouse in Xi'an. As we all know, cement is injected into the storage tank under high pressure. If the tank cannot reach normal pressure, it will definitely burst. This requires good breathability of the storage tank. While maintaining breathability, it is also necessary to prevent dust. The general method is to connect a pipe at the top to the ground filter cloth or water inlet tank. This measure is basically sufficient and cost-effective. Dust removal manufacturers have warehouse top dust collectors, which have better effects. A level gauge can be used for level warning and material bridging. Flow aid air cushions and flow aid air discs (vibrating air blowing) can be used, and air hammers are suitable for sand silos. Ingredients: Pneumatic valves can be installed at the raw material warehouse and conveyor port to achieve linkage. The valve at the discharge port of the screw conveyor can ensure the self flow of materials and prevent the buffer material from entering the ingredient scale.

Construction preparation
1. Quality management at the construction site should have corresponding construction technical standards, a sound quality management system, construction quality control, and quality inspection systems. Before grouting, there should be a construction organization design or construction technical plan, which should be reviewed and approved.
Before grouting construction, mixing equipment, grouting devices, templates, and maintenance items should be prepared.
3. In addition to complying with the relevant provisions of the current national standard "Code for Acceptance of Construction Quality of Concrete Structures" GB 50204, formwork support should also comply with the following regulations:
① During secondary grouting, the horizontal distance between the formwork and the equipment base should be controlled at around 100mm; The top elevation of the template should not be lower than 50mm above the surface of the equipment base.
② When renovating and reinforcing concrete structures, sufficient grouting holes and exhaust holes should be left in the formwork support. The diameter of the grouting holes should not be less than 50mm, and the spacing should not exceed 1000mm. The grouting holes and exhaust holes should be 50mm higher than the high point of the holes.

There is also a type of liquid wax commonly applied to interior walls, which is a film material with the main drawback of affecting the natural texture of the stone. The emergence of permeable protective products is a major progress in the development and research of stone protective products, but their application time in China is not very long. This type of product often uses solvents or water as a medium to bring effective waterproof materials into the interior of the stone Form a deep protective barrier to keep water and some liquid pollutants out. This permeable protective product not only does not change the natural texture of the stone, but also maintains its breathability. Its performance is superior and scientifically reasonable. However, due to differences in the materials used, some products may have different waterproof, anti fouling, and anti oil effects, but most products have better effects.

construction method
▲ Mixing
When mixing cement-based grouting materials, water should be added according to the required amount of water for the product.
2. Cement based grouting materials should be mechanically mixed. When mixing, it is advisable to first add 2/3 of the water and mix for about 3 minutes, then add the remaining amount of water and mix until uniform. If there are specific mixing requirements for AGM-340 products, they should be mixed according to their requirements.
3. The mixing site should be close to the grouting site.
▲ Anchor grouting of foundation bolts
1. The construction process of anchoring anchor bolts should meet the following requirements: ① Cleaning hole 1 ② Cleaning accumulated water in the hole 1 ③ Removing oil stains and rust on the surface of the bolt 1 ④ Inserting bolt adjustment and fixing 1 ⑤ Mixing AGM-340 grouting material 1 ⑥ Building 1 ⑦ Maintenance 1 ⑧ Installing equipment.
When drilling anchor bolts, the horizontal deviation of the bolt holes shall not exceed 5mm, and the vertical deviation shall not exceed 5 °. The wall of the bolt hole should be rough, and the hole should be cleaned thoroughly without any floating dust, oil stains or other impurities. Before grouting, soak it in water for 8-12 hours to remove any accumulated water in the hole. When the ambient temperature is below 5 ° C, measures should be taken to preheat and maintain the temperature above 100 ° C.
Before grouting, the oil stains and rust on the surface of the anchor bolts should be removed.
When pouring the mixed cement-based grouting material into the bolt holes, the position of the bolts can be adjusted as needed. Vibration is strictly prohibited during the grouting process, and bolts cannot be adjusted again after grouting is completed.
5. The upper surface of the grouting layer inside the hole should be about 50mm lower than the surface of the foundation concrete.

At present, the technology of using insulation boards and one-time pouring of concrete to form reinforced concrete walls is widely applied. Its advantage is that the insulation layer and the main wall can be completed in one construction, thereby shortening the construction period. The insulation board used in pouring is mainly polystyrene board, and rock wool board pouring construction has never been carried out. We have conducted a series of studies on the cast-in-place technology of rock wool board and conducted cast-in-place experiments. The results show that the cast-in-place technology can also be applied to rock wool board, and its effect is also very good. This is mainly because the surface of rock wool board is rough, and its surface fibers are easy to bond with concrete, so the bonding strength between rock wool board and concrete is relatively high.
▲ Secondary grouting
The appropriate grouting method should be selected for secondary grouting according to the actual situation of the project. The process flow should meet the following requirements: ① Cleaning the equipment foundation ② Soaking in water 24 hours in advance ③ Clearing accumulated water before grouting ④ Preparation of construction equipment ⑤ Mixing AGM-340 grouting material ⑥ Secondary grouting ⑦ Curing.
Before grouting, the equipment base plate and concrete foundation surface in contact with the grouting material should be cleaned thoroughly, and there should be no loose crushed stones, floating slurry, oil stains, wax, etc. 24 hours before grouting, the surface of the foundation concrete should be fully wetted, and the accumulated water should be removed 1 hour before grouting.
During secondary grouting, grouting should be carried out from one side until it overflows from the other side, and grouting should not be carried out simultaneously from opposite sides. After grouting begins, it must be carried out continuously and the grouting time should be shortened as much as possible.
When the track foundation or grouting distance is long, it can be constructed in sections according to the actual engineering situation.
5. Vibration is strictly prohibited during the grouting process. If necessary, a grouting booster should be used (pushing the grouting material along the bottom of the grout flow direction, and it is strictly prohibited to push it from the middle or upper part of the grouting layer).
After the equipment foundation grouting is completed, it is advisable to cut a 45 ° angle outward along the edge of the bottom plate 3-6 hours after grouting.

Clay mineral based artificial stone is an artificial material made by firing clay, quartz sand and other materials at high temperatures. It can also be classified as artificial stone. There are many types of clay mineral based artificial stone, which are widely used and account for a high proportion of building decoration materials, represented by porcelain tiles, vitrified tiles, microcrystalline stones, etc. In recent years, with the advancement of technology, new varieties of artificial stone have also emerged in the field of artificial stone, such as composite artificial stone and composite panels. This indicates the widespread demand for artificial stone, and there will be more and more artificial stone projects in the future. We define artificial stone in such a broad context, partly because the maintenance and upkeep processes of all these hard materials are not fundamentally different from those of natural stone; On the other hand, this also provides us with broad ideas and expansion space for the stone care industry. With slight improvements, existing stone care technologies can be applied to a wider range of fields.
