In the deep foundation pit enclosure engineering, when the surrounding environment of the foundation pit is complex, if the treatment is not good, the seepage phenomenon will easily occur, and then affect the construction quality of the whole project. Therefore, many deep foundation pits are used nowDouble-wheel milling of soil-cement mixing wallIn order to provide good impermeability and ensure the quality of the project.
Compared to other processes,CSMThe construction method has great advantages in controlling the continuity of deep piles.CSMThe method uses two groups of milling wheels to rotate and stir horizontally in the axial direction to form a rectangular groove of improved soil. The vertical rotation of the large blade determines that the method of mixing soil is more uniform and sufficient, equal thickness into the wall, and the construction quality is better.
Technological advantages
(1) High cutting performance
Strong formation adaptability, dual-wheel milling deep mixing milling head with high100 kN/m The guide rod adopts winch pressure system, and the milling head tool adopts alloy material, so the milling head can cut and dig dense silt, silt and other hard strata, and can cut and dig in the sand and gravel layer.
(2) High stirring performance
The deep mixing milling head of dual-wheel milling is composed of multiple rows of cutting tools. The soil is cut by rotating the milling wheel at high speed, and high-pressure air is injected in the process of cutting, so that it has very good mixing performance.
(3) High cutting accuracy
The vertical monitoring device is installed inside the deep mixing milling head of dual-wheel milling, which can collect data in real time and output to the monitor in the operation room, and the operator can make real-time correction by analyzing it.
(4) can complete large depth construction
At present, the guide rod type double-wheel milling deep mixing equipment can cut the depth of stirring45m, the suspension type double-wheel milling deep mixing equipment cutting and stirring depth can be reached65m.
(5) High stability of equipment
The heavy milling head driving device and milling head of the double-wheel milling deep mixing equipment are both set at the bottom of the drill tool, so the overall center of gravity of the equipment is low and the stability is high.
