s2, implanting a metal implant net; determining the size of a pre-buried pipe body according to the specification of an ALC plate, determining the size of a metal net, sleeving the metal net outside the pre-buried pipe body, applying a tensile force to the two ends of the metal net, enabling the inner diameter of the metal net to shrink and attach to the outer wall of the pre-buried pipe body, heating the metal net by using a hot air gun or a flame spray gun and continuously applying pressure to the two ends, enabling a part of the metal net in the radial direction to be scalded into the outer wall of the pre-buried pipe, and removing the tensile force at the two ends after cooling to finish implantation;
s3, covering the resin insulating layer; when the resin insulating material is heated to a melt-bonding state, the resin insulating material is coated on the metal planting net in a brushing or immersing mode;
s4, covering a heat insulation layer; the heat insulation layer is covered on the resin insulation layer in a state that the resin insulation layer is still in a heating and fusion bonding state in a mode of spraying or immersing into slurry through an air gun;
s5, pipe arrangement; arranging the pre-buried pipe body into a die according to the specification of a process drawing;
s6, grouting and solidifying; pouring the slurry of the ALC plate main body into a pressure die, and then standing for maintenance to coagulate the slurry to form a blank;
s7, demolding and steaming; and (3) delivering the demolded blank into an autoclave through a trolley for autoclaved curing, so that the blank is subjected to physical and chemical reaction, and the finished wallboard body is formed after the blank steam curing is finished.
5. The production process of the pipeline integrated ALC plate according to claim 4, wherein the production process comprises the following steps of: the slurry material of the ALC plate main body comprises 30-45% of cement, 15-25% of lime, 35-45% of sand, 6-12% of fiber, 8-12% of reinforcing agent and 7-13% of foaming agent.
