Description
Technical field
The invention belongs to underground engineering technical fields, are suitable for filling for discarded underground people's air defense hole processing more particularly, to a kind of
Filling chock material and preparation method thereof.
Background technology
In sandstone industry, steel industry, a large amount of solid waste --- the mountain flour of mechanism sandstone production discharge and combustion
The sintering desulfuration lime-ash of coal burning boiler discharge is all outdoor stockpiling mostly, not only occupied ground, but also can cause environmental pollution.This
The processing and utilization of a little solid waste are the practical problems that must currently solve.
The end of the sixties, the beginning of the seventies, for the call of response " deep-cut hole, extensively store up grain, prepare against war and natural disasters ", China cities and towns start
Build the mass movement in bomb shelter.The construction of these underground people's air defense holes is random very big, and quality is not also high, in addition older aging, greatly
Approached is scrapped or has been scrapped more.At the same time, with the continuous propulsion of Development of China's Urbanization, it is difficult to avoid ground some buildings,
Rail traffic main line and urban road pass through these discarded underground people's air defense holes, are controlled if not discarding underground people's air defense hole to these
Reason, easily causes the serious consequences such as surface collapse.
Currently to the processing in discarded underground people's air defense hole, optionally use and beat digging up and filling in or using envelope storehouse method for strengthening or top
Method for strengthening or placement method are supportted by bomb shelter packing, wherein the most extensive with placement method.Traditional filler is with sand, mixed
Based on solidifying soil, mortar and cement base injection slurry.104099943 A of patent CN disclose " diaphram wall and discarded underground people's air defense
Engineering intersects processing method ", wherein people's air defense both ends is taken to block the deeper people's air defense hole of buried depth, intermediate perfusion mortar blocks
After hole backfill is closely knit, then the periphery soil body is further reinforced with high-pressure rotary jet grouting pile.103275460 A of patent CN disclose a kind of " people
Anti- plugging material, subway people's air defense reserving hole plugging structure and method for blocking ", wherein people's air defense plugging material are used by asphalt mixtures modified by epoxy resin
Fat, curing agent and building block filler hybrid modulation and cure, and subway people's air defense reserving hole plugging structure is reserved by being plugged in
The high intensity plugging material at hole both ends and intermediate fire prevention calking are formed.However, underground people's air defense hole is mostly in main city zone traffic
In the side ground of thoroughfare or residential building, it is necessary first to especially pay attention to disturbing influence of the filling construction to surrounding enviroment；Secondly, ground
Narrow space in lower people's air defense hole, construction channel set up difficulty, and need to consider that obturation is subjected to underground water for a long time in military service process
Immersion or drying and watering cycle.Thus, the above-mentioned published patent is not paid attention to filler and is filled out not fully for underground people's air defense hole feature
Fill rate and durability.
