Abstract

The invention discloses a pumping agentfor blowing silt solidified soil and a preparation method thereof. The provided pumping agent is compounded by lignin sulfonate, sulfonated tannin extract, sodium gluconate, polyethylene wax, polyacrylamide, talc and sodium carbonate. The weight part of each component is: 30 to 35 parts of the lignin sulfonate, 25 to 35 parts of the sulfonated tannin extract,2 to 4 parts of the sodium gluconate, 3 to 4 parts of the polyethylene wax, 1 to 2 parts of the polyacrylamide, 30 to 35 parts of the talc and 0.5 to 1 parts of the sodium carbonate. The pumping agent for hydraulic reclamation of silt solidified soil provided by the invention has the advantages of low addition amount, simple adding process and good environmental protection, and the addition of the pumping agent can significantly improve the fluidity, lubricity and stability of the fresh silt solidified soil, makes the low-water content fresh silt solidified soil (water content of 100 percentto 150 percent) to maintain good fluidity within 2h, ensures the late strength of the solidified soil and prolongs the pumpable time of the silt solidified soil, which helps to improve the efficiencyand quality of silt solidified soil hydraulic reclamation construction, and has obvious technical, economic and environmental advantages.

Description

technical field [0001] The invention relates to a pumping construction material for dredging and filling mud-solidified soil, in particular to a pumping agent for dredging and filling mud-solidified soil and a preparation method thereof. Background technique [0002] As a new type of environmentally friendly soft foundation and embankment reinforcement material, solidified soil has been successively used in the construction of seawall embankment cores, river embankment embankments, and sea reclamation land reclamation in recent years. In order to ensure the construction quality and efficiency, pumping dredging has become the first choice for the construction of silt-solidified soil. In order to make the newly mixed silt-solidified soil meet the requirements of pumping and filling, the method of increasing the water content of the silt-solidified soil is mainly used during construction to improve the fluidity of the silt-solidified soil. The water content of the solidified s...
