SMW construction quality assurance measures

1. Protection of pipelines in surrounding areas (1) Before construction, investigate the buried depth, path and surrounding distance of pipelines, especially large-caliber pressure pipelines, and set up monitoring points for real-time monitoring during the whole construction process. (2) When piping displacement alarm is given, effective measures should be taken immediately, such as controlling the construction speed of mixing pile and adjusting process parameters.

Key points of SMW construction technology

Key points of SMW construction technology: 1. Strict control of design requirements for slurry preparation. 2, the soil should be fully stirred, the sinking speed should be strictly controlled, so that the original soil is fully broken to help evenly mix with cement slurry. At the same time, in order to accelerate and reduce the impact on the surrounding strata, the stirring can be connected with compressed air for full stirring.

Brief introduction of SMW construction method

SMW construction method is to use multi - axis pile stirring machine in the project site one by one construction. The cement slurry or soil curing agent is spouted from the drill bit and mixed repeatedly with the foundation soil to form a continuous and complete underground wall with certain strength and stiffness without joints. Suitable for building foundation pit retaining wall, water curtain or soft foundation soil reinforcement.

SMW

SMW is the abbreviation of the Soil Mixing Wall, which was introduced in Japan in 1976 and is now widely used in the open tunnel enclosure and deep foundation pit waterproof curtain. In this method, a multi-axis drilling mixer is used to drill at a certain depth on site, and the curing agent is sprayed at the bit to continuously mix and stir with the soil. Each pile body is constructed by lapping.

Basic regulations for construction of double - wheel milling cement - soil mixed wall

The double-wheel milling soil-cement mixing wall has large wall depth, wide range of formation adaptation, good continuity and uniformity, and excellent water interception and seepage prevention performance. In the engineering practice at home and abroad, it is commonly used as the water cutting curtain, the cutoff wall in hydraulic engineering and the isolation wall in environmental engineering. In some projects, the deep ground water is cut off by milled cement-soil mixing wall, and good results are obtained.

Machining and insertion of H - shaped steel in cement - soil mixing wall with double - wheel milling

Tandem mill mixing cement-soil wall CSM technique, it is on the basis of hydraulic slotting machine equipment, combined with the deep mixing technology, innovate and underground continuous wall and the construction technology of combining hydraulic slotting machine equipment technical characteristics and application field of deep mixing technology, the equipment is applied to the more complex geological conditions, as the protection of foundation pit excavation supporting structure. After the wall is formed, &NBSP is inserted in the slot; H-shaped steel to withstand the bending moment during the excavation process.

TRD pile construction, the introduction of cement - soil mixing wall technology of equal thickness

TRD (Trench Cutting re-mixing Deep Wall Method), also known as the same thickness of soil-cement mixing Wall technology, is a new type of soil-cement mixing Wall construction technology. This method changes the traditional horizontal layered mixing method of vertical axis auger into horizontal axis saw-chain cutting box, and the whole mixing method is vertical along the wall depth. The main engine power box hydraulic motor drives the saw-chain cutting box, and the cutting box is segmented and lengthened.

Introduction of construction technology of double - wheel milling cement subsoil diaphragm wall

Construction Technology of double wheel milling diaphragm wall under cement soil (&NBSP; CSM construction method combines hydraulic milling machine and deep mixing technology. By mixing the soil and cement slurry in situ at the construction site, it can be used for seepage prevention wall, retaining wall, foundation reinforcement and other projects. Compared with other deep mixing technology, CSM construction method has higher adaptability to the stratum and can cut hard soil (gravel bottom, rock layer).

Principle and advantage of undisturbed soil - taking and pressure - irrigation pile

The principle of undisturbed earth taking and pressure pouring concrete pile is a new type of reinforced concrete cast-in-place pile technology. Inherited the technology of long spiral drilling pressure filling pile, the advantages of using spiral drill drill to pile bottom, first buried spiral drill into a pile of pile hole, and then through concrete hollow drill pipe will flow by continuous injection to the bottom of the hole orifice, the formation of plain concrete pile, the use of vertical transmission functions of helical blade at the same time, remove the undisturbed soil pile hole, remove the soil and pile head floating pulp, after will The whole steel cage is inserted into the concrete pile body, and the concrete in the hole is vibrated to form the reinforced concrete cast-in-place pile without mud skin.
