Expansion-joint-free silt light soil for roadbed and construction technology
The invention discloses expansion-joint-free silt light soil for a roadbed and a construction technology. The expansion-joint-free silt light soil comprises flow-state solidified soil and an additional material. The flow-state solidified soil is prepared from the following components in parts by weight: 700 to 1000 parts of sludge slurry and 170 to 280 parts of an inorganic composite curing agent, the additional material is prepared from the following components in parts by weight: 31-47 parts of foaming liquid, 3-6 parts of a water reducing agent, 4-8 parts of an early strength agent, 7-14 parts of an expanding agent, 3-6 parts of a water retaining agent and 4-8 parts of bamboo fibers. The urea early strength agent introduced into the light soil can improve the early strength of the light soil, and the risk of light soil cracking caused by unstable foundation bearing or shrinkage in the early stage of construction is reduced.
本发明公开了一种路基用免伸缩缝淤泥轻质土及施工工艺，包括流态固化土和外加材料；所述流态固化土按照重量份数，由下述组分组成：淤泥泥浆700‑1000份，无机复合固化剂170‑280份；所述外加材料按照重量份数，由下述组分组成：发泡液31‑47份，减水剂3‑6份，早强剂4‑8份，膨胀剂7‑14份，保水剂3‑6份，竹纤维4‑8份。在轻质土中引入的尿素早强剂可提升轻质土早期强度，降低施工前期因地基承载不稳定或收缩引起轻质土开裂的风险。
