The invention belongs to the technical field of drainage pipes, and particularly relates to a compression-resistant municipal drainage pipe which comprises drainage pipe bodies and flange plates. Every two adjacent drainage pipe bodies are connected through one flange plate; and each drainage pipe body comprises an inner pipe and an outer pipe, wherein a, b and c parts between the inner pipe and the outer pipe are connected through supporting columns, a decompression unit is arranged at a d part between the inner pipe and the outer pipe, and the decompression unit comprises a first rod, a second rod, a third rod, a fourth rod and a sliding block. Each drainage pipe body is divided into the inner pipe and the outer pipe, the decompression unit is arranged between each inner pipe and the corresponding outer pipe, and when each outer pipe is subjected to external pressure, the pressure borne by the outer pipe is reduced through the sliding of the corresponding sliding block on a sliding groove, so that the pressure transmitted to each inner pipe is lower than the pressure borne by the inner pipe, each inner pipe is protected, the problem that breakage of each inner pipe affects transportation of water in a municipal area is avoided, and therefore the service life of the drainage pipe is prolonged.
本发明属于排水管技术领域，具体的说是一种抗压市政排水管；包括排水管本体和法兰盘；相邻排水管本体间通过法兰盘连接；排水管本体包括内管和外管，且内管和外管间的a、b和c处通过支撑柱连接，内管和外管间的d处设有减压单元，减压单元包括一号杆、二号杆、三号杆、四号杆和滑块；通过将排水管本体分为内管和外管，并在内管与外管间设置减压单元，当外管受到外界压力，通过滑块在滑槽上的滑动，削减外管受到的压力，使得传递到内管时的压力低于内管所能承受的压力，对内管进行保护，避免导致内管的破裂，影响市政地区水的输离，从而提高排水管的使用寿命。
