Abstract
The invention provides a device and method for controlling the direction and elevation of a lattice column below the ground. The problems that the elevation cannot be controlled and the direction of the lattice column is difficult to control on the construction site due to the fact that the top elevation of the lattice column is below the ground can be solved. Under the condition that the top elevation of the lattice column is below an original ground elevation, the elevation of the lattice column can be controlled, and the direction of the lattice column can be positioned. By making the center of the lattice column to coincide with the center of an inner square frame, two opposite sides of the lattice column are made to be parallel to two opposite sides of the inner square frame, and the other two opposite sides of the lattice column are made to be parallel to the other two opposite sides of the inner square frame, so that the lowering process is more accurate, the direction of the lattice column is rapidly controlled, and the requirements for the direction of the lattice column are met. The length of the lattice column is extended through the connection of an adjusting tool head and the lattice column, the adjusting tool head is placed on a shelving bracket trough a connecting component, and thus the elevation of the lattice column is controlled more intuitively and accurately.
