Abstract
The invention discloses a reinforcing method of a pile body. The method comprises the steps: adding power and/or slurry into an unset cement soil pile body, a cement gravel pile body and a concrete pile body, wherein a pile body material is close to a plastic limit water content state due to the adding amount of the powder and/or slurry; and then compacting the pile body. The method disclosed by the invention is simple to construct, and the pile body has excellent effects of high density and high strength.
Description
Technical field
The present invention relates to a kind of reinforcement means of pile body.
Background technology
The material compositions such as existing cement great soil group pile body, cement sandstone class pile body, concrete class pile body are single, water content does not conform to
Suitable, packing deficiency causes intensity not enough, and needs are further improved.
The content of the invention
It is an object of the invention to provide the cement great soil group pile body of a kind of high density, high intensity, cement sandstone class pile body, concrete
The reinforcement means of class pile body.
The present invention technical solution be：
A kind of reinforcement means of pile body, is characterized in that：Add powder and/or slurry in not solidifying pile body, the powder and/or
The addition of slurry makes the close plastic limit water content state of pile body；Then closely knit process is carried out to pile body or concrete pile body, is realized highly dense
Degree, high intensity.
The pile body is cement great soil group pile body, cement sandstone class pile body, concrete class pile body etc..
The powder, slurry are the powders such as cement, flyash, superfine silica powder, superfine steel slag slag powders, alkali-activator,
It is then slurry with suitable quantity of water.So that the close plastic limit water content of material of body of a pile is defined, now pile body can under closely knit process for water distribution quantity
Up to maximum dry density.
The method of the closely knit process includes that compacted, densification, spiral back-pressure, rotation expand, vibrate squeezed, compacting, deep layer in hole
Strong rammer, ram stirring etc..
The cement great soil group pile body, cement sandstone class pile body, concrete class pile body etc. can be used as the peripheral pile of composite pile, monomers
Vertical reinforcement etc. in stake, composite foundation.
Easy construction of the present invention, makes pile body have high density, the excellent effect of high intensity.
With reference to embodiment, the invention will be further described.
Specific embodiment
A kind of reinforcement means of pile body, adds powder and/or slurry, the powder and/or slurry in not solidifying pile body
Addition make pile body be close or equal to plastic limit water content state；Then closely knit process is carried out to pile body or concrete pile body, is realized high
Density, high intensity.
The pile body is cement great soil group pile body, cement sandstone class pile body or concrete class pile body.
The powder is cement, flyash, superfine silica powder, superfine steel slag slag powders, alkali-activator powder；Powder water distribution
It is then slurry.
The method of the closely knit process includes that compacted, densification, spiral back-pressure, rotation expand, vibrate squeezed, compacting, deep layer in hole
Strong rammer rams stirring.
Peripheral pile, the monomer stake or compound of the cement great soil group pile body, cement sandstone class pile body, concrete class pile body for composite pile
Vertical reinforcement etc. in ground.
