TRD pile construction process

TRD pile construction technology uses chainsaw cutter as the main tool to cut underground soil, and cement as the hardener to form a continuous wall of equal thickness underground. Then, H-shaped steel is inserted as the stress strengthening material according to the designed spacing before cement-soil hardening. After the cement-soil hardening, a composite retaining wall with certain stiffness and strength or only water stop is formed to form the overall foundation pit supporting system.

Deep mixing technology of soil-cement in foundation pit support

Water in the foundation pit supporting of deep mixing method by high pressure jet grouting or mixing machinery, special machinery, deep in the ground to curing agent (cement or cement powder, plus certain admixture) and force on the mixing of foundation soil, hardening of the wholeness, water stability and forms after a certain strength of cement-soil pile or cement clod body, thus improve the strength of foundation, The method of enhancing its deformation modulus.

Introduction of stiffened pile technology for strong foundation

Rotary jet mixing stiffening pile is a kind of oblique cement cement stiffening anchor solid formed by combining rotary jet grouting and mixing cement soil technology, and combining prestress and soil reinforcement technology. The strength of the slope soil is greatly improved, and the bearing capacity and stability of the slope soil are improved. At the same time, the anchor cable can obtain a high anchorage force to provide support for the foundation pit and slope stability.

Grouting reinforcement foundation treatment technology

Grouting reinforcement method is a kind of common reinforcement methods of ground treatment, and is the solidification of slurry, cement or other chemical grout) injection of rock and soil foundation cracks or pore, out of the water and gas, the connection between soil particles, after hardening and intensity of rock and soil can be consolidated into one big, the waterproof performance is good, good chemical stability of the overall, Thus, the purpose of strengthening foundation, preventing or reducing penetration and uneven settlement can be achieved.

TRD construction method pile construction preparation

1Before site preparation, site leveling must be carried out first, and the inner side of the construction site enclosure center line must be cleared15Most of the surface and underground obstacles in the range of meters, especially the surface mixed fill soil, contain more construction waste such as stones, bricks and concrete blocks, which must be followed before constructionTRDThe construction axis of the piling machine shall be cleaned and no large stones or concrete blocks shall be ensured, and the site shall be leveled to the natural ground-0.300m(Relative elevation). The roadbed of the construction site bears loads to be able to walk100Tons of the shoe......

Compaction, compaction and compaction of foundation treatment

Compaction, compaction and compaction of foundation refers to the large area of soil filled foundation, or natural soil structure loose, large pores, can not meet the requirements of foundation bearing capacity or deformation, or sandy soil liquefaction under earthquake load, collapsible soil under hydraulic action of subsidence and other engineering hazards. A treated foundation that compacts, compacts or compacts the soil structure, reduces porosity, eliminates liquefaction or collapsibility, and meets the bearing capacity or deformation requirements of the foundation.
