In coastal areas where the foundation soil is mainly clayey soil, sandy soil, silt and silty soil, wet-working hole-forming cast-in-place piles are widely used. However, a large amount of mud will be produced during the construction process. If it is not consumed in time, it will seriously pollute the surrounding soil and environment, and even cause the project construction progress to stagnate and the project quality to be damaged. Therefore, it is necessary to treat the waste mud. Explore and optimize.
At present, the harmless treatment method of mud is relatively single. Generally, it is piled in a centralized manner and then dried naturally. A small amount of admixtures are added locally for solidification. This takes a long time and the problem of large consumption area is becoming increasingly prominent. The contradiction with the construction of ecological civilization is increasingly intensified. . With the development and application of building technology and construction technology, new technologies such as mud dehydration and solidification technology and rapid and harmless treatment are becoming increasingly mature.
Among them, the
Filter Press is a common equipment used for
Solid-Liquid Separation in the chemical and pharmaceutical fields. After development and practice, it has also been used to a certain extent in the field of mud solidification in pile foundation engineering.
The industry has proposed a mud solidification construction method for chamber filter presses. This construction method is to send the mixed mud to the
Filter Plate of the filter press for sealing and pressurization, filter it with
Filter Cloth, separate the solid and liquid, and transport the solid mud cake out for consumption. After the clean water is treated with chemicals and reaches the standard, it is discharged to the nearby municipal pipe network. A method that can effectively solve the problem of mud transportation and consumption that has troubled construction companies for many years.
