Abstract
The method for reinforcing soft soil ground base is characterized by that in the ground base to be reinforced a deep-layer stirring method is adopted to infiltrate dried cement powder or cement slurry into soil layer, then a cement soil pile is made by means of stirring process, and the central position of said cement soil pile is drilled by spiral drilling machine, and then the concrete can be deposited to obtain the invented reinforced compresol pile.
Description
The present invention relates to foundation reinforcement method, promptly a kind of composite pile construction.
In order to reinforce soft soil property base, existing traditional method is varied.The stake of cement mix is exactly one of method, but the mix stake pile strength that this construction technology is made is low, can not adapt to the needs of engineering.
Purpose of the present invention is exactly that a kind of worker's method that improves cement mix stake pile strength will be provided, and can accomplish effectively, and environmental protection does not disturb residents.
The object of the present invention is achieved like this: in the cement mix pile center of having solidified,, take out the slag charge of boring with auger jewel hole pore-forming, with concrete pump in the hole from bottom to top concrete perfusion make reinforced bored concrete pile.
Along with the raising of people's environmental consciousness, the problem that construction disturbs residents is sharp-pointed all the more, and particularly the pile-driving method that some disturbs residents in the metropolis is in fact unworkable.The present invention is because to be to use the characteristics of its maximum of auger boring be noiselessness, friction, and the welcome of surrounding resident of being constructed does not deeply disturb residents.
Pile body length of the present invention has three kinds of situations in the construction: promptly with auger when the cement earth pile centre-drilling hole system concrete pile that has solidified, the length of cement earth pile pile body can be less than the concrete pile at its center, and the concrete pile stake that also can be equal to or greater than its center is long.Below in conjunction with accompanying drawing the present invention is described.
Fig. 1 is a reinforced bored concrete pile schematic diagram of the present invention.Shown in the figure be: soft earthen foundation 1, the cement earth pile made from deep mixing method water leaking-in mud dry powder or cement paste 2 at the concrete perfusion 3 then of sodified water earth pile center jewel hole pore-forming, and is put into reinforcing cage 4 with auger, makes reinforced bored concrete pile.
Figure 2 shows that three kinds of pile body length combination of the reinforced concrete pile at cement earth pile and its center.
Claims (2)
1, a kind of foundation reinforcement method is characterized in that making reinforced bored concrete pile in the cement mix pile center of having solidified with auger bore and concrete perfusion.
2, foundation reinforcement method according to claim 1 is characterized in that the length of cement earth pile pile body can be less than the concrete pile at its center, and the concrete pile stake that also can be equal to or greater than its center is long.
