Tunnel inverted arch red mud base filling layer material and preparation and construction method thereof
The invention relates to the field of tunnel inverted arch filling materials, filling layer construction and industrial solid waste utilization, in particular to a tunnel inverted arch red mud base filling layer material and a preparation and construction method. The red-mud-based filling layer material comprises the following components: red mud, lime, cement, steel slag, disodium ethylene diamine tetraacetate, water and a Tushenda curing agent. The tunnel inverted arch red mud base filling layer material is prepared from, by mass, 51.7% of red mud, 5.8% of lime, 5.8% of cement, 11.6% of steel slag, 5.8% of ethylene diamine tetraacetic acid disodium salt, 16.1% of water and 3.2% of a Haenda curing agent, the density of the red mud base filling layer material is about 2.0 t/m < 3 >, the unconfined compressive strength within 28 days can exceed 7.0 MPa, the preparation process is simple, and the cost is low. The strength of the red mud-based filling material obtained after red mud modification meets the requirements of tunnel inverted arch filling layer materials.
