This invention relates to a modular, assembled transmission tower foundation and its construction method. The transmission tower foundation includes four pile columns, a base, a bearing plate, a guide and locking mechanism, and a compression-type protective sleeve. The guide and locking mechanism is located between the bearing plate and the base, and achieves precise guidance and locking between modules through the insertion of connecting rods and connecting sleeves. The compression-type protective sleeve is slidably fitted onto the outer wall of the bearing plate and the base, and has a damping slip layer between it and the internal structure to withstand soil frost heave force and slide relative to it, thereby cutting off the transmission path of frost heave force to the main bearing structure. This invention solves the problems of difficult construction of traditional cast-in-place foundations in complex geological areas, foundation instability caused by frost heave force, and poor grounding. It features modular rapid assembly, strong frost heave resistance, and high structural stability, and is suitable for the construction of transmission line projects in complex geological areas.

The application relates to a cattle neck fixing device based on a feeding fence, which comprises a feeding fence, a swing rod, a swing rod adjusting assembly and a swing rod stopping assembly.
