Description
Technical field
It is especially a kind of using porous particle as the microorganism cement of carrier the utility model is related to a kind of civil engineering technology
Native mixing pile preparation facilities.
Background technology
The weak soil in China is largely distributed in coastal area, is developed rapidly with the economy of the southeastern coastal areas, in weak soil
Infrastructure or the construction of progress underground engineering are carried out on this special soil layer also to be become increasingly frequently.Soft soil foundation has
There are low permeability, high-compressibility and low intensive feature, so to carry out infrastructure on such foundation soil, it is necessary to
Foundation soil is reinforced, since pile foundation is suitable on the middle and senior level and large-sized workshop, therefore in the foundation stabilization of region following the line of the sea, is used
The engineering that pile foundation is reinforced also is compared all, but Cement Deep Mixing Column Intensity is insufficient.
When microorganism consolidated subsoil soil, in order to ensure microorganism under its optimal temperature, ensure that microorganism is newly old
The high efficiency of metabolism is, it is necessary to give certain heating measure when it is reacted, and it is simple that microorganism is reinforced with reinforcement principle, reaction speed
Rate is controllable, it is environmental-friendly the features such as, but reinforce after the soil body still have certain water penetration, still have much room for improvement in terms of antiseepage,
A most important problem is that the soil body after microorganism is reinforced, intensity homogeneity is bad, first contacts the local intensity of bacterium solution
Higher, the calcium carbonate content of generation is more, but the soil body of contact bacterium solution afterwards, and intensity is relatively low, the content of the calcium carbonate of generation
It is less.
Cement mixing method is a kind of effective form for the treatment of of soft foundation, is a kind of host agent using cement as curing agent, profit
Cement jet is entered into the soil body with mixing pile machine and is sufficiently stirred, makes cement that a series of physical chemical reaction occur with soil, makes weak soil hard
It ties and improves the site works mechanical equipment of foundation strength.But mixing pile transfers the energy of load since compression modulus is smaller
Power is smaller, therefore under load action, the load of most of cement mixing method has all been only left at pile body top, in this way, smaller
Frictional force effect under, pile side friction has reached the limit and has been destroyed, thus Cement Deep Mixing Column Intensity and
The general rigid pile bearing capacity of bearing capacity ratio is small.
