Second, if you still want to use the screw connection method: 1, the foundation can use 16 chemical bolts (four); 2. The steel plate 300×300× 16 has four bolt holes with the diameter of 18. The steel plate 100×55×6 is processed into a stiffening plate, and both sides of the steel plate are fully welded with steel pipes. According to the size of the structural high heel foundation; 5, the hole is invalid; 3. Connect and fix 16 bolt with steel plate (to ensure smoothness), which is made by our own experience to avoid column corrosion caused by cleaning pig farm during use?

First of all, the simplest method is to bury the pipeline directly in the foundation. Give the specific construction technology and details to the masters; 4. Only consider the anchorage length, weld galvanized pipe along the pipeline and stand on the steel plate!

However, the pig farm should be corrosive, and it is suggested that the foundation should be higher than the ground in the farm.
