我国对于管道地下铺设有着明确要求,本文浅析热水管道直埋无补偿敷设技术,希望对实践工作开展起到借鉴意义。一、直埋敷设与地沟敷设直埋敷设是指将热水供热管网直接埋于土壤深处,并且管道的外表面会直接与土壤成分接触。与其相对应的是地沟敷设,不难理解地沟敷设是指将供热管道敷设在特制的地沟内。地沟大多数都是用砖配合混凝土制成,供热管道不直接与土壤接触,从而一点都不会承受土壤带来的压力,更不受土壤中有机成分的腐蚀。管理简单维护方便,维护时不需要
China has a clear requirement for underground pipe laying. This paper analyzes the laying technology of buried hot water pipe without compensation, hoping to draw lessons from practical work. Buried laying and trench laying Buried laying refers to the hot water heating pipe network buried directly in the soil depth, and the outer surface of the pipe will be in direct contact with the soil composition. Corresponding to the laying of the trench, it is not difficult to understand the trench laying refers to the laying of the heating pipe in a special trench. Most of the ditches are made of bricks and concrete, and the heating pipes are not in direct contact with the soil, so that they will not withstand the pressure of the soil and will not be corroded by the organic components in the soil. Easy management Simple maintenance, maintenance is not required
