Self-sealing type flow state solidified soil and backfilling technology thereof
The invention provides self-sealing type flow state solidified soil and a backfilling process thereof. The self-sealing type flow state solidified soil is prepared from the following raw materials in parts by weight: 100 parts of soil materials, 7-25 parts of a curing agent, 1-10 parts of an additive and 20-50 parts of water, the slump degree of the prepared self-sealing type flow state solidified soil is 200-280mm, and the expansion degree is greater than 300mm; the curing agent is prepared from the following raw materials in parts by weight: 4-10 parts of a cementing material, 1-5 parts of an additive and 2-10 parts of water. Under the action of self gravity, the self-compacting type flow state solidified soil can automatically flow, compact and fill any corner of a pipe ditch, meanwhile, good homogeneity can be obtained, and a solid structure with certain compaction degree and strength can be formed without additional vibration. And after curing, the structural strength is high, the sealing performance is good, and the water permeation risk during pipeline use is greatly reduced.
本发明提供了一种自密式流态固化土及其回填工艺，自密式流态固化土由以下重量份的原料制备而成：土料100份，固化剂7～25份，外加剂1～10份，水20～50份；所制备的自密式流态固化土坍落度为200～280mm，扩展度大于300mm；固化剂由以下重量份的原料制备而成：胶结料4～10份，外加剂1～5份，水2～10份。本发明的自密式流态固化土在自身重力作用下，能自行流动、密实并充满管沟的任何角落，同时可获得良好均质性，不需要附加振动就可形成具有一定压实度和强度的固体结构。并且固化后结构强度高、密封性好，大大降低了管道使用时的透水风险。
