Abstract
Manually digging hole and full-sleeve engineering method bored concrete pile bottom installation rubber bag tank (chamber) Post Grouting Technique are suitable for foundation and underground space field of engineering technology, background technique is to use the drilling of mud off at present, steel reinforcement cage bottom such as installation steel plate capsule, it be easy to cause borehole wall to collapse, keep bottom hole sediment exceeded, it is also easy to accumulate the silt to get off that collapses from hole wall above steel plate, influences the quality of cast-in-situ bored pile.The most prominent feature of the present invention is to have found a restrictive condition and applicable elements for the bottom installation closed slip casting of slip casting container, to the effect that pouring pile hole utilizes manually digging hole or full-sleeve engineering method, pore forming process does not use mud off, Grouting Pipe is bound on steel reinforcement cage, steel reinforcement cage bottom is installed by steel plate, rubber bag tank is installed in steel plate bottom surface, and Grouting Pipe passes through steel plate and is connected with rubber bag tank.After above-mentioned engineering method pore-forming, bottom hole will be arrived under steel reinforcement cage, then start concrete perfusion, after pile strength is met the requirements, by Grouting Pipe to the rubber bag tank slip casing by pressure of stake bottom.
Description
Technical field:
Ground and base basis underground space engineering technology
Background technique:
At present in foundation field, what bored concrete pile Post Grouting Technique was included in building pile foundation specification is open type slip casting, because
Relatively easy for open type slip casting implementation process, Grouting Pipe is with the process under steel reinforcement cage to bottom hole to hole wall especially before perfusion
Disturbance very little, but its slurries of open type slip casting note domain controllability is low, formation to stake end enlarged footing and to surrounding formation
The amplitude that compacted effect and bearing capacity of pile tip improve is not if any the closed slip casting of slip casting bag (chamber).Stake bottom has slip casting bag (chamber)
Although closed slip casting according to the requirement of slip casting " three fixed ", i.e. orientation, localization and quantitative aspect has more superiority, is using
During the bored pile construction of mud off, there is also apparent defects.Steel plate capsule such as is installed at steel reinforcement cage bottom
(chamber) is used as grouting behind shaft or drift lining container, and during under with steel reinforcement cage to bottom hole, the steel reinforcement cage with protection steel plate is in the borehole still
It such as piston, is easy to form vortex in slime water, makes to circle round and the mud current scour between steel plate edge and the wall of a borehole and disturb
Dynamic borehole wall, the steel plate of bottom are also easy scratch borehole wall, these factors all be easy to cause borehole wall to collapse, cause through
In slip casting container, metapore bottom sediment is again exceeded on earth for drilling after crossing borehole cleaning, while the upper surface of steel plate is also easy accumulation from drilling hole
Collapse the silt to get off on wall, influences the quality of cast-in-situ bored pile, broken pile is caused when serious, if protection steel plate diameter compares
It is small, or because of other reasons such as collapse hole is superfilled, pile grouting capsule (chamber) can also occur and wrapped up by concrete close, work cannot be played
With the phenomenon that, this is also the closing that drilled pile tail band is clearly had slip casting bag (chamber) by technical code for building pile foundation (JGJ94_2008)
The main reason for formula grouting method forecloses (see provision explanation).
Summary of the invention:
The present invention " rubber bag tank (chamber) Post Grouting Technique is installed at manually digging hole and full-sleeve engineering method bored concrete pile bottom " is a kind of pass
The new technical solution after the improvement of pile foundation technical method, the most prominent feature of the present invention are to have found that bottom installation slip casting is held
The restrictive condition and applicable elements of the closed slip casting of device, this technical solution are bottom installation rubber bag tank (chamber) Post Grouting Techniques and fill
Infuse the most reasonable assembled scheme of stake drilling construction method, can solve it is above-mentioned there are problems, the technical solution is simple, practical, makes
Bored concrete pile Post Grouting Technique is more reached perfection.To the effect that pouring pile hole utilizes manually digging hole or full-sleeve engineering method, pore-forming
Process does not use mud off, and Grouting Pipe is bound on steel reinforcement cage, and steel plate is installed in steel reinforcement cage bottom, and rubber bag tank is installed in steel plate bottom surface,
Grouting Pipe passes through steel plate and is connected with rubber bag tank, and steel plate main function is protection capsule.Using manually digging hole or full-sleeve engineering method
After pore-forming, bottom is equipped with to the steel reinforcement cage of steel plate rubber bag tank, it is lower to arrive bottom hole, then start concrete perfusion and forms bored concrete pile,
After pile strength is met the requirements, built-in slip casting pipe is begun through to the rubber bag tank slip casing by pressure of stake bottom, to the stratum of bored concrete pile bottom
It is compacted to carry out densification, final result is to effectively eliminate a bottom sedimentation, increases substantially ultimate bearing capacity of pile tip, reduces engineering and make
Valence.
Specific embodiment:
1, do not made first, in accordance with design requirement using manually digging hole or full-sleeve engineering method pore-forming, pore forming process in building-site
With mud off, Grouting Pipe is bound when making steel reinforcement cage, steel plate is installed in steel reinforcement cage bottom, and rubber bag tank, note are installed in steel plate bottom surface
Slurry pipe is connected across steel plate with rubber bag tank, and steel plate main function is protection capsule.
2, after using manually digging hole or full-sleeve engineering method pore-forming, bottom is equipped with to the steel reinforcement cage of steel plate rubber bag tank, under arrive
Then bottom hole starts concrete perfusion and forms bored concrete pile, after pile strength is met the requirements, begins through built-in slip casting pipe to stake bottom
Rubber bag tank slip casing by pressure, compacted to the stratum progress densification of bored concrete pile bottom, final result is to effectively eliminate a bottom sedimentation, substantially
Degree improves ultimate bearing capacity of pile tip, reduces project cost.
3, the present invention " rubber bag tank (chamber) Post Grouting Technique is installed at manually digging hole and full-sleeve engineering method bored concrete pile bottom " is suitable for
Cohesive soil, silt, husky class soil, rubble class soil and rock weathering layer.
Claims (2)
1. invention " rubber bag tank (chamber) Post Grouting Technique is installed at manually digging hole and full-sleeve engineering method bored concrete pile bottom " is one kind about stake
