Description
Technical field
The utility model relates to building foundation field of engineering technology, specifically, relates to a kind of reinforcing cage cement earth pile.
Background technology
Excavation of foundation pit is basic and first operation in underground engineering construction, again a comprehensive geotechnical engineering difficult problem simultaneously, it had both contained typical Strength and stability problem in soil mechanics, contained problem on deformation again, also related to soil and the coefficient problem of foundation pit enclosure structure simultaneously.The space enclosing structure of foundation ditch mainly bears pressure of soil pressure, hydrostatic pressure and the surrounding building transmission outside foundation ditch etc., in deep foundation pit engineering in urban, mostly adopts steel sheet pile, deep-mixed pile, bored pile and diaphragm wall to make space enclosing structure.SMW engineering method utilizes special multi-shaft stirring rig, creep into the cutting soil body on the spot, from its chisel edge, cement paste is injected the soil body simultaneously, after being fully uniformly mixed with the chopping soil body, again by shaped steel normally H profile steel or other core insert in stirring body, form diaphragm wall.SMW engineering method is succeeded in developing in Japan the earliest, and it is on the basis fully summarizing steel concrete diaphragm wall and cement-soil mixing pile pluses and minuses separately, by the two organically combine, learn from other's strong points to offset one's weaknesses development.It had both overcome deep-mixed pile does not have the shortcomings such as reinforcing bar, intensity are not high, poor continuity, it also avoid steel concrete construction of diaphragm wall complexity, has mud contamination, high cost problem.Shaped steel Soil-cement Wall comes from the MIP engineering method (Mixing in-PlacePi1e) of the U.S..In the tentative construction of MIP engineering method that 1955 carry out at An Zhichuan riverside, Osaka City, attempt MIP engineering method successively sequential production being made one colonnade formula diaphragm wall, the blank of SMW engineering method that Here it is.As far back as the 80's Mos, shaped steel Soil-cement Wall once caused the concern of China's engineering circles, and had done some researchs, but not in practical engineering application.China's case history is the earliest the global world mall Foundation Pit Support Engineering near Jing'an Monastery, Shanghai in 1994, engineering obtains successfully, but do not accomplish the recycling of shaped steel, therefore bracing engineering cost does not have advantage compared with bored pile, because groundwater resources are deficient, all parts of the country all restriction Dewatering, the construction method of traditional pile-anchor retaining+tube well dewatering receives restriction, and pile-anchor retaining+curtain with rotary jet grouting piles or diaphragm wall cost very high.
So, develop that a kind of steel utilization rate is little, cheap, the pile-type of easy construction, just become the problem that insider needs solution badly.
Utility model content
For the above-mentioned technical problem in correlation technique, the utility model proposes a kind of reinforcing cage cement earth pile, take into account supporting and dash effect, cost relative moderate, and easy construction.
For realizing above-mentioned technical purpose, the technical solution of the utility model is achieved in that
A kind of reinforcing cage cement earth pile, comprise some arrangement of reinforcement soldier piles and agitation pile of connecting of being staggered, described arrangement of reinforcement soldier pile comprises cement-soil tube core, described cement-soil tube core skin is provided with bearing rod, described bearing rod skin is provided with stirrup, further, be provided with between described bearing rod and described stirrup some with the longitudinal centre line of cement-soil tube core for benchmark and the main muscle of array arrangement.
Further, described reinforcing cage cement earth pile comprises fixed section and cantilever segment.
Further, in described cement-soil tube core, cohesive soil cement mixed ratio is 22% ~ 27%, water content be 25% ~ 35% cement-soil slump value be 200mm ~ 210mm, silt cement mixed ratio is 18% ~ 23%, water content be 35% ~ 42% cement-soil slump value be 190mm ~ 200mm.
Further, sulfuric acid calcium powder, aluminium hydrate powder and calcium chloride granules is added with in described cement-soil tube core.
The beneficial effects of the utility model: the utility model is convenient to gather materials on the spot, wide material sources, take into account supporting and dash effect, cost relative moderate, have that bending resistance is higher, strong adaptability, and with waterproof between piles curtain synchronous construction, technological process is simple.
