[0026] By arranging an I-shaped joint 8 between adjacent first T-shaped walls 5 and adjacent second T-shaped walls 6, a plurality of first T-shaped walls 5 and a plurality of second T-shaped walls 6 are connected as a whole through the I-shaped joint 8, and are respectively adapted in the outer longitudinal groove 2 and the inner longitudinal groove 3; by arranging a cross joint 9 at both ends of the straight wall 7, the cross joints 9 at both ends of the straight wall 7 can respectively contact the first T-shaped wall 5 and the second T-shaped wall 6, so that the first T-shaped wall 5, the second T-shaped wall 6 and the straight wall 7 are connected as a whole, thereby achieving the purpose of reinforcing the grid-shaped underground continuous wall.
[0027] Specifically, in this embodiment, the plurality of I-shaped joints 8 are flexible joints, and the dimensions thereof are 916 mm×450 mm×8 mm.
[0028] By installing a plurality of I-shaped joints 8, a plurality of first T-shaped walls 5 and a plurality of second T-shaped walls 6 are respectively connected as a whole, so as to achieve the purpose of bearing lateral water and soil pressure.
[0029] Specifically, in this embodiment, the plurality of cross joints 9 are rigid joints, which are welded with 20 mm thick steel plates.
[0030] By installing a plurality of cross joints 9, the first T-shaped wall 5, the second T-shaped wall 6 and the straight wall 7 in the same vertical direction are connected as a whole, so as to bear the vertical load of the upper structure.
[0031] Specifically, in this embodiment, the steel plates of several cross joints 9 close to and perpendicular to one end of the straight wall 7 are ordinary steel plates, and the steel plates of one end of the cross joints 9 close to and perpendicular to the first T-shaped wall 5 or the second T-shaped wall 6 are fully welded with threaded steel bars with a diameter of 25 mm on both sides.

[0042] Specifically, in this embodiment, a special steel wire wall brush is used when the cross joint 9 is brushing the wall.
[0043] Since the joint surface of the cross joint 9 is narrow, the wall brush is driven up and down by the rotary drilling machine, so that the concrete blocks on the joint surface can be effectively removed.
