When raining, rainwater permeates into the wall body along the gaps under the action of wind pressure and further permeates into the wall, so that the inner side wall surface coating is skinned, blackened and the like. The current regulation provides that the method for solving the rainwater leakage is to carry out professional waterproofing (take measures such as applying waterproof mortar and waterproof paint) on the outer side of the wall body. The outer wall is professionally waterproof, so that the construction cost is increased, and quality accidents such as hollowing of a plastering layer, falling of tiles and the like are frequently caused.

A method for building a rainproof dry wall building block wall body comprises the steps that the rainproof dry wall building block wall body comprises a rainproof building block for a dry wall built in the central part and an auxiliary building block built on the uppermost layer; the auxiliary building block (9) is a cuboid solid building block, and four sides of at least one side surface of the auxiliary building block (9) are provided with chamfers (91); the rainproof building block for the dry wall comprises a cuboid building block body (1), wherein a water blocking ridge (2) along the length direction is arranged on the top surface of the cuboid building block body (1), and a bottom groove (3) capable of containing the water blocking ridge (2) along the length direction is arranged on the bottom surface of the cuboid building block body (1); vertical grooves (4) are formed in the vertical surfaces of the two ends of the cuboid block body (1); the water retaining ridge (2) of the next-layer rain-proof building block for the dry wall is embedded into the groove on the bottom surface of the last-layer rain-proof building block for the dry wall to form an interlocking structure; the two left and right adjacent dry walls are butted by using the vertical grooves (4) of the rainproof building blocks to form a vertical diversion hole (7), and a diversion strip (71) is arranged in the diversion hole (7) close to the outer wall surface; the auxiliary building block (9) of the uppermost building block is embedded on the wall surface outside the dry wall;
the building method is characterized by comprising the following steps:
a: the application occasions are as follows: the construction beam and the construction column are covered in the dry wall;
firstly, pouring a plain concrete ridge (A) at the position of a wall root according to the designed height and width, arranging a water retaining ridge with the same cross section shape as that of a water retaining ridge (2) of the rainproof building block for the clear water wall on the upper surface of the plain concrete ridge, and enabling the difference between the elevation of the upper surface of the plain concrete ridge (A) and the elevation of the concrete plate bottom at the position to be just the height of the rainproof building block for the clear water wall; and the outer surface of the wall body built by the dry wall with the rainproof building blocks protrudes the outer surface of the plain concrete ridge by 25-20 mm;
b: building a first waterproof wall rainproof building block on the plain concrete ridge by using bonding mortar; enabling the rain-proof building blocks for the dry wall to protrude 25-20mm from the outer surface of the plain concrete ridge;
c: when a first or later brickwork is built, scraping and coating adhesive mortar on two sides of a water retaining ridge of the plain concrete ridge or the water retaining ridge (2) of the waterproof wall rainproof building block, and immediately building a waterproof building block for the waterproof wall above the plain concrete ridge, wherein a water diversion strip (71) is immediately inserted into a water diversion hole (7) close to the outer wall surface after each building of one waterproof building block for the waterproof wall;
d: after the last skin building block is built, the last skin of the building wall is built by adopting the auxiliary building block (9); before the auxiliary building block (9) is built, a common brick block (94) and common mortar (95) are adopted to fill the space under the beam from one outdoor side, sufficient space is reserved for inlaying the auxiliary building block (9) during filling, the filling method is a conventional inclined building compaction method, and waterproof mortar (92) is adopted to cover the common brick block;
e: inlaying the last auxiliary block (9), wherein the outer surface of the auxiliary block (9) protrudes out and floats out of the concrete plate end and the outer side surface of the plain concrete ridge (A) by about 25-20mm during inlaying, and the four corners of the auxiliary block (9) are firmly bonded;
f: and (3) coating cement mortar on the plain concrete ridge and the end part of the concrete plate on the outdoor side of the rainproof dry wall building block wall built by the procedures, immediately coating thermal insulation mortar (93), and making a decorative seam consistent with the decorative seam (8) of the masonry, thus finishing building.
