Coal gangue roadbed treatment method
The invention discloses a coal gangue roadbed treatment method which comprises the following steps: step 1, temperature measurement: distributing points along the two sides of the middle line of a roadbed, and carrying out temperature exploration on a coal gangue mountain in a roadbed section; a low-temperature area roadbed and a high-temperature area roadbed are divided according to the temperature exploration result of the coal gangue hill in the roadbed section, and the low-temperature area roadbed comprises a prevention and control area and a critical area; the high-temperature area roadbed comprises a heat storage area and an ignition area; 3, treating a roadbed in a low-temperature area; subgrades of the prevention and control area and the critical area are constructed by adopting a longitudinal excavation method, and a layer of loess is excavated and covered in time; and 4, high-temperature area roadbed treatment is conducted, specifically, before excavation construction of a heat storage area and an ignition area, the temperature of waste gangue slag is reduced in a drilling grouting fire extinguishing mode, and then construction is conducted according to a low-temperature area roadbed. Before roadbed construction, the coal gangue mountain is subjected to temperature measurement and zoning, corresponding treatment measures are taken for the low-temperature area roadbed and the high-temperature area roadbed, the roadbed construction technology is optimized, and construction safety and quality are guaranteed.
本发明公开了一种煤矸石路基处理方法，包括以下步骤：步骤1：测温：沿路基中线两侧布点，对路基段内煤矸山进行温度探查；步骤2：分区：根据对路基段内煤矸山进行温度探查的结果，划分出低温区路基和高温区路基，低温区路基包括防控区和临界区；高温区路基包括蓄热区和发火区；步骤3：低温区路基处理；防控区和临界区路基采用纵向开挖法施做，开挖一层用黄土及时覆盖；步骤4：高温区路基处理：蓄热区和发火区开挖施工前采用钻孔注浆灭火的方式降低矸石弃渣温度，然后按照低温区路基施工。本申请在路基施工前，对煤矸石山进行测温、分区，针对低温区路基和高温区路基，采取相对应的处理措施，优化路基施工工艺，保证了施工安全和质量。
