Further describe in detail below.
The technological process of Percussion Piles construction is as follows:
One, surveying setting-out
The datum mark provided according to proprietor by professional survey engineer, accurately measures the stake position of every pile with total powerstation, and is buried in the earth with reinforcing bar and performs mark, and fixing, notices that protecting the stake position of non-construction stake to mark does not destroy by disturbance before construction.
Two, pile-forming machine perching
Stake machine telephone-moving align piles position, makes a machine overhead traveling crane leading edge, board on same plumb line, and levels up by Zhuan Wei center, pad.
Three, bury casing underground
Casing adopts steel pile casting, and diameter is greater than intended diameter 20cm, and casing is imbedded to firm stratum, casing top 20 ~ 30cm above ground level, and casing center line and pile center's line hang down and close.
Four, pore-forming
Adopt mud off pore-forming, in creeping into, the scarfing cinder of slag cylinder and the clear hole of gas lift reverse circulation are drawn in the employing of clear quarrel.
Bright according to geology MSDS, there is thicker gravel in this place, medium-sand seam, bedrock surface big rise and fall, inclination angle is large, and the feature of hole deviation easily occurs, and keeps noticing that mud balance controls at 1.2 ~ 1.45kg/L, viscosity 25 ~ 30S during pore-forming.At loose stratum and sandy gravel stratum, keep mud balance at 1.3 ~ 1.45kg/L when creeping into, drilling speed is unsuitable too fast, to form good pit protection mud cake, keeps punching to stablize.Pore-forming must enter middle decayed rock sand and be not less than 0.5m, reaches design elevation.
Along with the increase of hole depth in rushing in, for making sediment return out aperture in a large number, improving pore-forming efficiency, adopting pneumatics blower fan to send at the bottom of compressed air to hole during scarfing cinder, utilizing gas lift reverse circulation to carry out scarfing cinder at the bottom of hole.
When rushing in bedrock surface, must the speed of rushing in be slowed down, avoid inclined hole.When impact holing, should hole quality be kept a close eye on, for Different Strata, select different stroke and regulate mud property, should low hammer be close hits during initial punching, after entering basement rock, higher hammer detritus.
Five, clear hole
Rush in and adopt the clear hole of gas lift reverse circulation to projected depth, sediment thickness should be less than 50mm, in order to ensure clear hole quality, after descending reinforcing cage, still must continue clear hole.
Implement the system of sediment at the bottom of a kind of detect aperture of the present utility model, there is following useful technique effect:
Be different from the deficiency that prior art thoroughly can not remove sediment, the technical program thoroughly can remove sediment, decreases that pile position deviation is excessive, stake holes tilts to exceed standard, the deficiency of pipe laying, reinforcement cover, improves construction quality.
The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
