基于赣龙铁路扩能改造临近车站开挖石方方案及单价分析

Analysis of Rock Excavation Scheme near Station and Unit Price Based on Capacity Expansion and Renovation of Ganlong Railway Project

赣龙铁路扩能改造工程,其瑞金车站石方开挖临近既有瑞金车站和站内油库等危险源,为保证施工安全,不能采取爆破施工。通过对施工方案的研究,决定采取人工凿除或机械凿除的施工方法。因现行铁路工程定额中没有机械开挖石方的计价依据,故此文依据赣龙铁路扩能改造瑞金车站石方开挖施工组织和方案,并结合现场具体情况,进行工料机消耗的测定,分析机械开挖石方的综合单价。

The rock excavation of Ruijin station in Ganlong railway capacity expansion and renovation project is close to the existing Ruijin station and the oil depot. In order to ensure the construction safety,the blasting construction can not be adopted. Through comparative analysis of construction scheme,it is decided to adopt the construction method of manual or mechanical excavation. However,there is no pricing basis of mechanical excavation rock in the current railway engineering quota. the consumption of labour,materials and machines is measured according to the construction organization scheme of rock excavation at Ruijin station. And the comprehensive unit price of mechanical excavation rock is analyzed.
