The invention discloses a high-strength compression-resistant polyolefine clad pipe for architecture, prepared from the following components: 70-100 parts of polyolefin resin, 5-13 parts of high-strength compression-resistant master batch, 1-10 parts of glass fibers and 0.3-0.7 part of compatilizer, wherein the high-strength compression-resistant master batch is prepared from the following components: 60-90 parts of high flow rate polypropylene, 15-25 parts of nano-calcium carbonate, 15-35 parts of metal oxide, 0.1-0.3 part of coupling agent, 0.2-0.8 part of antioxidant and 0-2 parts of other additives. The invention also discloses a method for preparing the high-strength compression-resistant polyolefine clad pipe for architecture. According to the high-strength compression-resistant polyolefine clad pipe for architecture, the high-strength compression-resistant master batch and glass fibers are added to the polyolefin resin and both can improve the strength of the clad pipe; the high-strength compression-re
