Embodiment 1

[0021] Divide the reinforcement area into reclamation ponds to naturally evaporate part of the water in the reclamation sea mud in each reclamation pond, so that the sea mud reclamation has a predetermined bearing capacity; The weight percentage is evenly distributed on the surface of the dredging sea mud of each dredging tank; the saponified slag and the dredged sea mud are fully mixed and evenly dried; the mixed and aired saponified slag and the dredged sea mud are mixed together Gather and dry in the sun for 5 days, the water content of the saponified dregs formed is 40% by weight; the saponified dregs are paved and compacted, and the dry bulk density is 1.30g / cm 3 , the bearing capacity of the reinforced foundation is 65kPa.

Embodiment 2

[0023] The reinforcement area is partitioned to form reclamation pools, and part of the water in the dredging sea mud in each reclamation pool is naturally evaporated, so that the dredging sea mud has a predetermined bearing capacity; The dry weight percentage is evenly distributed on the surface of the dredging sea mud of each dredging tank; the saponified slag and the dredged sea mud are fully mixed and evenly dried; the mixed and aired saponified slag is mixed with the dredged sea mud Pick up and pile up and dry in the sun for 15 days, and the water content of the saponified slag formed is 25% by weight; 3 , the bearing capacity of the reinforced foundation is 90kPa.

Embodiment 3

[0025] The reinforcement area is partitioned to form dredging ponds, and part of the water in the dredged river mud in each dredged pond is naturally evaporated, so that the dredged river mud has a predetermined bearing capacity; The dry weight percentage is evenly distributed on the surface of the dredged river mud in each dredged tank; the saponified slag and the dredged river mud are fully mixed and evenly dried; the mixed and dried saponified slag is mixed with the dredged river mud Pick up and pile up and dry in the sun for 20 days, and the water content of the saponified slag formed is 30% by weight; the saponified slag is paved and compacted, and its dry bulk density is 1.45g / cm 3 , the bearing capacity of the reinforced foundation is 120kPa.

Abstract

The present invention discloses a saponified slag soil. It is formed from saponified slag and hydraulically-filled soft soil according to the dry weight percentage of 1:3-1:5. Said invention also provides a method for strengthening hydraulically-filled soft soil by using saponified slag, and provides its concrete steps. Said invention can effectively reduce contruction cost of marine soft soil ground treatment, and can effectively shorten construction period.

Description

technical field [0001] The invention relates to a kind of saponified slag, and also relates to a method for reinforcing dredging and filling soft soil. Background technique [0002] Saponification slag is an industrial waste discharged during the production of propylene oxide, which is essentially Ca(OH) 2 The calcium carbide with lower content has not been developed and utilized for many years and can only be stockpiled. It not only causes serious pollution to the environment, but also becomes a key factor restricting chemical plants from expanding the production scale of propylene oxide. Therefore, conducting special research on the development and utilization of saponification slag, making it a material resource, will have a positive impact on the development of similar enterprises producing propylene oxide across the country and produce significant environmental benefits. [0003] With the development of my country's economic constructio...
