[0037] Such as figure 1 As shown, the present invention includes the following steps:
[0038] Step 1. Construction preparation: Calculate the size of the wall casing prefabricated block and determine the bottom elevation of the wall casing prefabricated block; the wall casing prefabricated block is a cubic concrete block, and the constructed wall casing 2 is poured In the concrete block; the length A, width B, and height C of the prefabricated block of wall-through casing are respectively determined, A=1.2α~1.5α, α is the diameter of the wall-through casing 2, and B is equal to The thickness of the construction wall, the wall to be constructed is a wall made of blocks and for the wall sleeve 2 to pass through; C=α+ΔH top +ΔH bottom ,among them
[0039]
[0040]
[0041] Where H 1 Is the thickness of the block; H 2 Is the thickness of the mortar joint of the wall to be constructed; H top Is the top elevation of wall casing 2, H bottom Is the bottom elevation of wall casing 2; ac...
