In the in-service use, will connect the boss 41 size greatly increased at body 40 tip, set up to be all bigger than current boss 41 size, its benefit mainly reflects: if the boss hole is left on the inner and outer walls 11 by the boss 41 at the later stage, after filling, a crack appears at the joint, the size of the boss 41 is increased, the distance between the crack and the pipe hole can be increased, water on the outdoor side C is prevented from permeating into the pipe hole from the crack and then permeating into the indoor side B, and the waterproof and anti-seepage effects of the inner and outer walls 11 can be further improved; and when the expansion type waterproof mortar 110 is filled at the later stage, the boss hole can accommodate more expansion type waterproof mortar 110, so that the waterproof effect can be further improved. Similarly, in the boss 41, the connection conical surface 412 is provided to facilitate the extraction of the embedded pipe 4, the wall thickness of the embedded pipe 4 is uniform, and the manufacture is simple.
Wherein the second end surface 411 is flush with the outer wall side of the inner and outer walls 11, and one end of the pipe body 40 away from the second end surface 411 is flush with the inner wall side of the inner and outer walls 11; therefore, the first template 1 and the second template 2 can clamp the insert 4 when the insert 4 is disposed in the cavity 10.
And S4, filling the expansion type waterproof mortar 110 and the foaming polyurethane 111 at the two ends and the middle part of the pipe hole left by drawing the embedded pipe fitting 4 out respectively. Specifically, the inner wall sides of the inner and outer walls 11 are filled with the intumescent waterproof mortar 110, the middle of the pipe hole is filled with the foamed polyurethane 111, and then the outer wall sides of the inner and outer walls 11 are filled with the intumescent waterproof mortar 110. Because the two ends of the pipe hole respectively correspond to the indoor side and the outdoor side of the inner wall body 11 and the outer wall body 11, the two ends are filled with the expansion type waterproof mortar 110, and the condition that cracks appear in the pipe hole after the inner wall body 11 and the outer wall body 11 are used for a long time can be prevented as much as possible; the middle part of the pipe hole is mainly filled with the foamed polyurethane 111, the density and the quality of the foamed polyurethane 111 are relatively small, the compressibility is strong, the weight of the inner wall body 11 and the outer wall body 11 can be reduced, and the service life of the inner wall body and the outer wall body is prolonged; and in the process of expansion with heat and contraction with cold, the condition of cracks or bulges is prevented.
Preferably, the bosses 41 are completely filled with the intumescent waterproof mortar 110 in the boss 41 holes formed in the inner and outer walls 11, and the outer diameter of the first end surface 410 of the boss 41 is much larger than the maximum outer diameter of the pipe body 40, so as to ensure that if cracks occur in the later period, the cracks can move outwards and are far away from the left holes of the pipe body 40; the filling amount of the large-size boss 41, which is equivalent to the expansion type waterproof mortar 110 filled in the boss hole, is increased.
In the whole forming process of the inner wall body 11 and the outer wall body 11, the inner wall 43, the outer wall 42, the water stop ring 44 and the boss 41 of the embedded pipe fitting 4 are structurally arranged to play a role in multiple waterproof, and the two ends of the pipe hole are filled with the expansion type waterproof mortar 110 to plug and seal the two ends of the pipe hole, so that the conditions of cracks and water seepage at the pipe hole after long-time use are prevented; the expansion type waterproof mortar 110 is filled at the two ends of the pipe hole, and the foaming polyurethane 111 is filled in the middle of the pipe hole, so that the condition that cracks appear at the filling position of the pipe hole in the process of expansion caused by heat and contraction caused by cold of the inner and outer wall bodies 11 can be ensured, the weight of the inner and outer wall bodies 11 can be reduced, and the service lives of the inner and outer wall bodies can be prolonged.
Specifically, in this scheme, body 40 boss 41 with seal ring 44 is integrated into one piece, and body 40 and boss 41 are coaxial setting, and specifically, pre-buried pipe fitting 4 accessible extrusion or injection moulding, no matter be small batch or big batch all can realize.
In the scheme, the inner and outer wall bodies 11 formed by the construction method have good waterproof and anti-seepage effects; due to the special structure of the embedded pipe 4, the conical surfaces of the inner wall 43 and the outer wall 42, the large-size boss 41, the connecting conical surface on the boss 41 and the water stop ring 44, the embedded pipe 4 has multiple waterproof effects, is convenient to use, simple in structure, reusable, low in construction cost and investment-saving, and is an energy-saving and environment-friendly construction method.
