The utility model discloses a combined polyvinyl chloride hollow wall silencing pipe, which aims at solving the problem of low working efficiency caused by the fact that a product cannot be integrally taken and placed, and is characterized by comprising an inner layer pipe and an outer layer pipe which are detachably combined, and the outer circumference of the inner layer pipe and the inner circumference of the outer layer pipe are provided with slot structures which are matched with each other; the inner-layer pipe extends into the outer-layer pipe and is limited through the inserting groove structure, and a hollow gap is formed between the inner-layer pipe and the outer-layer pipe. The combined inner and outer layer structure, the outer layer solid wall pipe and the inner layer foaming pipe are adopted, so that the impact performance of a non-standard product is improved, and the product is prevented from being broken during assembly and disassembly; the inner-layer foaming pipe improves the sound insulati
