Problems solved by technology

This processing method is primitive and backward, which has caused many problems
First, the cost is high and the efficiency is low. When the construction is tense, the day and night transportation of tank trucks cannot meet the construction progress requirements
Second, the environment at the construction site is harsh, and muddy water is overflowing, making it difficult to get in. The engineering team often suffers huge fines due to muddy water leaking into the sewer and causing pipeline blockage
In addition, tank trucks often pollute the city environment due to mud water leaking on the urban arterial roads during transportation.

Abstract

The invention provides a slurry modifying agent. A small number of exciting agents are used for exciting the activity of ore slag and sludge; in addition, waterborne bonding agents such as cement andlime are mixed for replacing the conventional water hardening curing materials; mixed furnace is used for grading silt slurry soil particles, so that the intensity reaches the engineering soil requirements. The invention also provides an engineering slurry modifying method. Solid waste material of the ore slag, furnace slag and the like are used as major materials of the slurry modifying agent; the production and processing cost is low; the cut concretion water-resistant performance is good; argillization cannot easily occur; the intensity is high; the high popularization and use value are realized.

Description

technical field [0001] The invention relates to the technical field of chemical engineering, in particular to a mud modifier and a modification method for engineering mud. Background technique [0002] Piling mud water is a suspended liquid containing a certain amount of fine mud particles in water. It has a certain viscosity and is difficult to separate after a long period of standing. In the pile foundation engineering of urban building construction, mud water plays an important role in protecting the well wall, but the treatment of excess mud water has always been a problem that plagues engineering construction. [0003] The current treatment method is to transport the on-site muddy water to the suburban garbage dump with tank trucks, and let it dry naturally. This processing method is primitive and backward, and has caused many problems. First, the cost is high and the efficiency is low. When the construction is tense, the day and night transportation of tank trucks ca...
