TRD construction equipment with wall formed in middle

The utility model relates to the technical field of water conservancy project seepage prevention, in particular to TRD construction equipment with a wall formed in the middle. The TRD construction equipment comprises a frame, a chassis used for driving the frame to walk, and a working device used for cutting the stratum. The chassis are arranged at the bottom of the frame in pairs in the front-back direction, and the frame can drive the chassis arranged in the front-back direction to be unfolded and folded in the horizontal direction. And the working device is fixed in the middle of the frame. By arranging the frame capable of being unfolded and folded, the two chassis at the bottom of the frame can move relatively, so that the distance between the chassis is adjusted, and the construction distance between dams and the road transportation requirement are met. The working device is arranged between the two chassis, so that the chassis can walk on the two sides of a construction position, and the TRD constructi
