Problems solved by technology
The cement-soil mixing technology still has the following technical problems: First, the mixing of cement and in-situ soil needs to be uniform, so the more times of mixing the better, but the more times of mixing, the longer the construction time and the lower the work efficiency; The resistance of the mixing equipment is too large, the drill bit and the mixing blade are seriously damaged, and the phenomenon of drill sticking is easy to occur

Embodiment 1
[0044] The performance of surfactant is carried out half-life test, and the preparation process of surfactant foam is as follows:
[0045] Such as Figure 1~3 As shown, a modification method of a surfactant is characterized in that the surfactant and pure water are respectively placed in the storage tank 1 and the water tank 3, and then the surfactant is prepared into a stable pole by the following modification method Micro Bubbles:
[0046] Step 1: Connect and debug all equipment and pipelines;
[0047] Step 2: Turn on and adjust the No. 1 pipeline booster pump 2 and the No. 2 pipeline booster pump 4, so that the surfactant and pure water are mixed in the mixing chamber 5 to form a surfactant mixture with a specified concentration;
[0048] Step 3: Perform secondary treatment on the surfactant mixture of specified concentration to form a surfactant in the form of tiny bubbles;
[0049] Step 4: pump the secondary-treated surfactant in the form of tiny bubbles to the high-pr...

Abstract
The invention discloses a method for modifying a surfactant, which belongs to the technical field of cement-soil mixing pile construction. The preparation method mainly includes: opening and adjusting the No. 1 pipeline booster pump and the No. 2 pipeline booster pump, so that the surfactant and the No. 2 pipeline booster pump Purified water is mixed in the mixing chamber to form a surfactant mixture with a specified concentration, and the surfactant mixture with a specified concentration is subjected to secondary treatment to form a surfactant in the form of micro-bubbles, and the secondary-treated surfactant in the form of micro-bubbles The surfactant is pumped to the high-pressure gas processing chamber through the No. 4 pipeline booster pump, and the high-pressure gas is used to fully cut the surfactant in the high-pressure gas processing chamber, so that the surfactant forms stable and extremely small bubbles, and finally, pumped to Drilling rigs or other equipment for resistance reduction operations.
Description
technical field [0001] The invention relates to the technical field of cement-soil mixing pile construction in the field of foundation treatment, in particular to a method for modifying a surfactant. Background technique [0002] Our country has a vast territory, and there are soft soil layers of various origins, which have a wide distribution range and a large thickness of the soil layer. This type of soft soil is characterized by high water content, large void ratio, low shear strength, high compressibility, poor permeability, and long settlement stability time. In recent years, with the rapid development of engineering construction, it is often necessary to carry out construction on soft soil foundations. Due to the poor building performance of soft soil foundations, artificial reinforcement is required. There are many treatment methods for soft soil foundations, such as our common Excavating non-adaptable soil for replacement and filling, cement or lime stabilized soil ...
