The construction method of a novel wall structure according to claim 3, characterized in that: in the step (2.6), the width of the adhesive tape adhered to the gap between the blocks and the joint of the blocks and the ground is 25-35mm, the adhesive tape is tightly adhered, and the joint of the blocks and the ground is sealed in advance so as to avoid slurry leakage in the process of grouting the grouting bonding layer.
9. The construction method of a novel wall structure according to claim 3, characterized in that: in the step (3.2), grouting is carried out in a partition mode, the width of primary grouting is controlled within 5m, and the height of grouting is controlled within 1.5 m; the grouting holes are formed in the bottom or the top of the block where each grouting area is located.
10. The construction method of a novel wall structure according to claim 3, characterized in that: in the step (3.2), the manner of blocking the grouting hole is as follows: and putting the cut-off grouting pore plate back in situ, fixing the larger-size cover plate at the grouting pore position, connecting the cover plate to the wall body base layer through the fixing piece, and removing the larger-size cover plate and the fixing piece covered outside the grouting pore after the flowing slurry between the wall body base layer and the block surface layer is solidified to certain strength.
