Embodiment 1

[0064] The construction general contracting project of the CIC Land Beicheng Times (Phase II) project (Plot A) has a planned construction net land area of ​​64882.22m2 and a planned total construction area of ​​295131.07m2, of which the above-ground construction area is 213196.05m2 and the underground construction area is 81935.02m2. The architectural design of the construction site is ±0.00=409.50m, the leveling elevation of the site is considered as 406.0m~411.00m, and the excavation depth of the foundation pit is about 7.0m~13.0m;

[0065] (1) To prepare the solidified soil, communicate with the solidified soil unit in advance, through on-site survey, select the on-site construction station to supply the solidified soil for the construction, take the original soil from the site for the test mix of the solidified soil, and after the trial mix of the solidified soil, determine the solidified soil The mix ratio of the soil is curing agent: water: soil = 1:1.15:5.36. Considering...

Abstract

The invention provides a premixed flow-state solidified soil foundation trench backfill construction method. The method comprises the steps of solidified soil preparation, foundation trench cleaning,gravel drainage ditch construction, formwork erecting, layered pouring, surface scraping treatment, field finished product protection, solidified soil maintenance and the like. The method is convenient and fast in construction process, economical, convenient in material obtaining, good in stability, high in compactness, good in self-sealing performance and impermeability, and short in constructionperiod, compared with a traditional backfill construction mode that a small excavator and a tamping machine are used for backfilling, chute backfilling is used, vibration is not needed, layered construction joint faces can be well combined without chiseling, construction joints cannot be formed, and the problems that in traditional backfill construction, the construction difficulty is large, thebackfill construction period is long, and the backfill quality is difficult to control are solved.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a construction method for backfilling a ready-mixed fluid solidified soil foundation groove. Background technique [0002] In the process of backfilling fertilizer tanks of various projects, problems such as narrow backfilling space of fertilizer tanks, large backfill depth, and unstable quality of backfill soil tamping are often encountered. The traditional technology mostly uses plain soil or lime soil layered with small tamping equipment for construction, which is difficult to construct, has a long backfilling period, and is difficult to control the quality of backfilling. Contents of the invention [0003] The embodiment of the present invention provides a construction method for backfilling pre-mixed fluid solidified soil foundation grooves, which is convenient in the construction process, economical and economical, convenient in obtaining materials, good ...
