This is due to the different regions of the engineering geological conditions, soil distribution, physical and mechanical properties of different soils, even in the same building site, the soil is often not uniform, carrying out engineering survey, design and construction, if the master of the ground conditions incomplete, handled properly, it could lead to an accident, the current building was built reinforcement methods are many, but the most common are the following types: (1) Grouting Reinforcement: rig into the hole on the foundation to want soil reinforcement, and then use high-pressure grouting equipment will be formulated cement slurry poured into the chemical formation, by splitting, squeezing effect, so that the soil physical and chemical reaction resulting slurry cement, so as to improve the structure and properties of the soil aim to improve the strength of the soil. Foundation settlement perfusion repair and reinforcement for foundation settlement building repair, foundation reinforcement of anti-settlement approach, this method is simple and practical mature professional construction. (2) static piling reinforcement: the use of load-bearing columns of the building as an anti-gravity force, through a liquid (oil) pressure equipment, the sub-section precast piles buried in the upper and lower sections embedded pile feeder with angle iron welded . Pressure piles by hydraulic control, when the pressure reaches the design load and basically met the requirements of the final plan pile length pile, pile capacity at the end of the pile is reflected directly from the meter pile pressure device. After the final pile pile head pressed into the pile foundation and the original steel welded steel and pouring concrete pile cap and base as a single entity, which will load the upper structure are passed directly to the hard soil through piles. At present, more general point of view, pressure grouting method is a relatively small investment, fast and effective method; and static pressure pile reinforcement rule is considered a large investment and long duration basis, but very reliable foundation reinforcement methods. But for strip foundation of this project, because of its limited width of the strip foundation to withstand the upper load effect on soil additional stress, while the soil is still natural soil base outside the bar, without external applied load, small stress zone. When filling in the high-pressure driven by the stress along the slurry will be weak areas (zones) splitting diffusion, and therefore, under the section of the project-based grouting, soil slurry will strip foundation under limited improvement, The slurry will leak into the soft soil strip ran outside the base. After the foundation reinforcement, although partial improvement, but its force is still compressed layer of sand and soft soil cushion strip base under foundation settlement can not be fully under control, the deformation will continue to develop, the effect is not very obvious. The static piling method is to pile the pressure reinforcement to the foundation of the state of hard plastic sandy clay soil layer, the upper structure of the load is transferred through piles directly into the deep, hard soil borne by the state, so that the base under Article sand cushion and soft soil foundation in unloading state, and pile force and force directly, when the pressure piles pile bearing capacity may reflect pressure machine directly from the instrument, ground deformation can finally get control, so treatment effect is obvious.
