”For example, P&G formed a supply chain partnership with Wal Mart, Wal Mart POS system opened sales information about products to P&G, and P&G automatically replenished goods to Wal Mart distribution center. Wal Mart has eliminated a series of workload such as ordering and purchasing, and streamlined the huge distribution system; Procter&Gamble immediately obtained product market information, providing support for the effective operation of product development and supply chain. After a strong alliance, it will promote the development trend of stronger and larger enterprises, while enterprises that do not have the conditions will be marginalized in the process of supply chain integration.

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.

According to the different cementitious materials and functions used, artificial stone can be divided into resin type artificial stone, inorganic type artificial stone, functional type artificial stone, etc. Resin based artificial stone is a new type of building decoration material developed in recent years, which uses resin as the matrix and mixes different fineness fillers, different color pastes, and additives in a certain proportion. It is made through processes such as stirring, casting, bonding, and curing. Resin based artificial stone has the advantages of good mechanical properties, multiple refurbishments, and color modulation. Resin based artificial stone is divided into artificial stone granite (referred to as granite), artificial stone quartz stone (referred to as quartz stone), and artificial stone solid surface material (referred to as solid surface material).

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.

From arc plate cutting → multi head arc plate grinding → four blade arc plate cutting machine cutting → column seat and column cap shaping → Roman column groove. The entire system is produced automatically by machines, and workers only play a role in transporting and operating the machines during the production and processing process. The processing technology of Yunfu's circular arc plate is as follows: circular arc plate cutting → single saw blade circular arc plate trimming machine imitating circular arc plate → single head circular arc plate grinding machine grinding circular arc plate → four blade circular arc plate trimming length and height → column seat, column cap → manual Roman groove pulling. There is a huge gap in efficiency and economy between the imitation of single saw blade circular arc plate rounding machine, single head grinding of circular arc plate, and the one-time forming of multi head circular arc plate grinding machine with manual Roman groove and water head.
▲ 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.

The water absorption rate of sandstone is very high, and some varieties almost infiltrate the stone by pouring water on it. Sandstone has the characteristics of sound absorption, moisture absorption, fire resistance, and low gloss due to its high internal structural porosity. This type of characteristic is very ideal for decorating public places such as cinemas, sports halls, restaurants, etc. with sound absorption requirements, and can even eliminate sound-absorbing panels and frosted walls. According to China's "Limits for Radionuclides in Building Materials" (GB6165-21), the radioactivity of sandstone is not included in the scope of radioactive testing. This is based on long-term monitoring and extensive spot checks conducted during the formulation of standards. In fact, as a type of stone mainly composed of SiOAl2O3, it is an environmentally friendly, green, and reliable building material.
