摘要
电力管线作为最主要的市政公共设施之一,是一种重要的纳入城市地下综合管廊的管线设施。然而,城市地下综合管廊的收费定价模式尚未统一,也没有针对电力管线的收费方法的相关研究。因此,本文探讨了电力管线入廊的几种收费定价模式,并将几种模式进行了对比分析。以合肥市某综合管廊为例,计算了不同模式下,电力管线纳入综合管廊需要缴纳的入廊费和运营维护费。结果表明,根据架空线路的直埋成本计算的电力管线的入廊费最低,而根据电缆沟工程的直埋成本计算的入廊费较高。当管线单位与政府的分摊系数λ低于0.2时,通过直埋成本法计算的电缆入廊费与合肥市现行标准相符。不同方法计算的电力管线入廊的运营维护费差别不大,其中根据空间占比法计算的电力管线入廊运营维护费最高,而考虑利润率时,电力管线入廊的运营维护费最低。最后结合我国综合管廊收费定价模式存在的问题,提出了电力管线入廊收费定价模式的对策建议,期望对我国电力管线入廊以及其他管线入廊的收费定价标准的制定提供科学依据和决策参考。
As one of the major urban utilities,electrical cables are required to be installed in utility tunnels.However,the pricing methods of installation of electrical cables into utility tunnels are still non-standard.This article aims to investigate the pricing methods for installation of electrical cables into utility tunnels by a case study in Hefei.The results indicate that entrance fees of electrical cables on the calculation of overhead wires projects are lower than entrance fees calculated by cable trenches.When the allocation proportion is less than 0.2,the calculation is close to current standards.The differences on operation fees are not serious.In detail,the fees calculated by space proportion are the highest,while considering profit margin makes them the lowest.In order to encourage the installation of electrical cables in utility tunnels,it is recommended to standardize the pricing methods of electrical cables into utility tunnels.Current results are expected to make references for both electrical companies and the government.
