First, the base line of excavation protection According to the model of the glass tank in the engineering drawings, according to the model size, elevation, put the gray line to excavate the base slot. According to the provisions of the State's construction specifications, the excavation tank must be drained under conditions of high groundwater level.
Second, deal with the basic cushion
1. The foundation is waterless, natural soil, laying 200-300mm stone powder or yellow sand cushion, and need to remove the sharp angle stone and hard debris entrained in sand.
2. Based on the foundation of water or backfill soil, a 200mm concrete cushion is to be laid, and then 200-300 stone powder or yellow sand layer is to be laid.
Third, the equipment installed in place lifting must pay attention to the direction of import and export of glass tanks, the arrow indicates the end of the exit direction, check whether the requirements of the engineering design drawings, product lifting in place, the level of determination, partial adjustment cushion level .
Fourth, after the water filling installation is in place, the water is poured into the tank to make it stable. When the water injection volume reaches 1/3 of the height, it can be backfilled. When the earth is backfilled to the height of 1/2 of the glass tank, it needs to go to the glass body. Infuse water to the bottom of the outlet pipe before continuing to backfill.
5. Layered backfill shall be layered and compacted on the backfilled soil. It shall be carried out at 300mm per floor. It is advisable to use artificial compaction and avoid localized violent impact. The regulations for backfill operations in the construction code must be observed and the backfill surrounding the tank must be densely packed. It is strictly forbidden to use construction waste as garbage for backfilling of soil, and large sharp corner stones in filling should be removed.
6. After the back-filling of connecting wells meets the requirements of the construction specifications, an import and export link well (about 1m away from the tank body) can be built. Connect the well waterway according to the general plan construction, the bottom cushion must be rammed and then flowed to build the concrete floor, make the flow channel in the well, and strictly implement the engineering design elevation. After acceptance, it is strictly prohibited to pour in building rubbish and domestic garbage.
Zirconia Ceramic Structural Parts
Zirconium oxide ceramic structural parts have begun to be accepted by automobiles because of their excellent performance, which just makes up for the shortage of metal materials. For example, it has long-term endurance 20G vibration function; parts used in combustion and exhaust systems can withstand the rapid cooling of 50~60°C/S for a long time; due to strong mechanical performance reliability, the failure rate is usually below 10-5; Special ceramics have good bonding properties with metals and Other Materials; they can be mass-produced, and they are inexpensive, and are easy to form industrialized operations and so on.
