Variable section ground wall and guide wall baffle plate device capable of being recycled

The invention relates to a variable section ground wall and guide wall baffle plate device capable of being recycled. The device comprises a variable section guide wall baffle plate consisting of a main steel plate, lifting points, support pieces and fixing pieces; the support pieces are arranged on the two sides of the middle part of the variable section guide wall baffle plate, and the two sidesare fixed on the inner side of an original guide wall through the support pieces; and at least two lifting points are arranged at the top of the variable section guide wall baffle plate, and are in positioning fixed connection with the original guide wall through at least two fixing pieces. The device can be applied the construction phase of a small section at the lower part of a variable sectionunderground continuous wall or the condition of completing construction of a guide wall when a ground wall becomes thin, can perform the thinned ground wall on the basis of not destructing the original guide wall, can be recy
