Embodiment 1

[0031] In the self-compacting cement soil of the present invention, the cement is an inorganic gelling material, and the cement soil is diluted with water to increase its fluidity, and the water can be turned into a certain strength cement soil after natural evaporation.

[0032] In order to produce cement soil with appropriate strength, several sets of mix ratios are designed according to the site conditions, materials are configured according to the mix ratio, and the consistency testing equipment is used to test, and 0.7×0.7×0.7 test blocks are made, and the strength is tested after 7 days and 28 days of curing. The following table data is obtained:

[0033]

[0034] The self-tightening cement-soil mix ratio is determined through repeated tests. The cement content is 10%. After the water evaporates, its strength can reach more than 0.6Mpa after testing, which fully meets the strength requirements. The volume mix ratio of cement-soil is cement:soil:water =200:2000:1000 (f...

Abstract

The invention discloses a construction method for filling a cave dwelling with self-compacting cement soil. According to the construction method, the self-compacting cement soil is convenient to prepare, compared with foam lightweight concrete, the cost is low, the working efficiency can be improved effectively, the construction cost is lowered greatly, the problem that the backfilling quality ofa cave dwelling treatment project is difficult to ensure or the construction cost is high is solved, a cave opening is sealed by a brick wall and filled with soil for reinforcement, tightness of the cave dwelling is ensured, and the self-compacting cement poured in the cave dwelling can effectively improve the treatment quality of the cave dwelling; and the problems that the backfill quality of the cave dwelling treatment project is difficult to ensure or the construction cost is high and the construction process is complicated are solved.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a construction method for filling cave dwellings with self-compacting cement soil. Background technique [0002] Cave dwellings are an ancient living form of residents on the Loess Plateau in Northwest China, and are widely distributed in Shanxi, Shaanxi, Henan, Hebei, Inner Mongolia, Gansu and Ningxia provinces on the Loess Plateau. Cave dwellings generally have cliff-like cave dwellings, sunken cave dwellings, and free-standing cave dwellings, among which mountain kilns are more widely used. [0003] In the process of highway construction in the above-mentioned areas, it is easy to encounter caves under the bridge abutments that need to be treated. The caves are generally 7-8m away from the original ground, and the treatment methods generally adopt construction methods such as direct excavation, backfilling, and pouring foam lightweight concrete. , but generally ...
