[0047] S5. Press the middle part of the back support cross bar 214 onto the back support vertical bar 213, and then place the two ends of the back support cross bar 214 on the upper surface of the bottom support protrusion 23411 respectively.

[0048] S6. Press the middle part of the fastener 236 onto the end of the back support cross bar 214, and then use the first bolt 235 to fix the upper and lower ends of the fastener 236 to the upper and lower first plates 2332 respectively.

[0049] S7. Install the hoops 2141 at both ends of the back support cross bar 214 respectively, so that the side walls of the hoops 2141 are in contact with and press-fit the second cylinder 2341 and the second sheet 2342 .

[0050] Reference Fig.15 The top surface of the bottom support protrusion 23411 is in a horizontal L shape, thereby preventing the back support cross bar 214 from accidentally falling and ensuring construction safety.

[0051] After the steel mesh is arranged in the casting cavity, the concrete is cast; after the concrete is hardened and formed, the steel formwork 2, the wooden formwork 1 and the tie rod are removed to obtain the foundation.

[0052] The present invention has a simple structure and reliable functions. The second plate 22 and the hinge assembly 23 are used to pull the first plate 21 placed in the narrow fertilizer trough 4, thereby avoiding the problem that the diagonal bracing structure cannot be installed in the narrow fertilizer trough 4, and further avoiding the problem of reduced construction efficiency caused by expanding the foundation pit. Compared with the traditional hinge articulation, the present invention has higher structural strength, thereby improving the bearing capacity, and ensuring that the first plate 21 and the second plate 22 will not be disengaged when subjected to the expansion force of concrete.
