Embodiment Construction

[0021] The saponified slag discharged by the water method is used for the construction of the saponified slag foundation, and the humidity of the saponified slag is controlled within 10%. First, sample the saponification slag, conduct a mixing degree experiment, mix the saponification slag with the original soil of the foundation, and measure the compaction degree when the added volume of saponification slag is 5% and 8%, and obtain the saponification according to the measured compaction degree The optimal mixing volume ratio of slag; according to the optimal mixing volume ratio, saponification slag and foundation soil are mixed, and then the compaction test and the optimal humidity test after compaction are carried out according to two thicknesses of 30cm and 50cm.

[0022] Excavate drainage ditches on one side of the foundation to be constructed for drainage, and then turn over the foundation to be constructed, with a thickness of more than 1m and reduce the moisture content ...

Abstract

The invention relates to a construction method of a saponified slag foundation. The construction method is simple and direct, and high in economic benefit. By adopting the construction method, the construction of the saponified slag foundation having the optimum performance is realized through control of simple coefficients of saponified slag and original soil, so that the saponified slag foundation which can be stable for a long term is formed.

Description

technical field [0001] The invention belongs to the construction technology of road foundation, and in particular relates to a construction method of saponified slag foundation using a mixture of saponified slag and soil as the foundation material. Background technique [0002] Saponification slag is a by-product of chemical products produced with calcium carbide as raw material in the factory. It is generally discharged by water method. It enters the draining pool from a flowing state. After draining, it is in a plastic state. It is excavated and stored or directly discharged to ash storage for large-scale natural dehydration. The chemical composition of raw materials for the production of calcium carbide, the main component is Ca, with Ca(OH) 2 and CaCO 3 It exists in a mixed form, and the content of the toxic substances arsenic As and cyanide CN in the impurities is lower than the pollution control standard stipulated in GB12502-90. The properties of saponified slag and...
