Abstract
The invention discloses sand added cement-soil stirring pile construction equipment, which comprises a drill rod, wherein the drill rod is provided with a cement-soil spouting pipe. The construction equipment is characterized in that: the drill rod is also provided with a sand blast pipe for blasting sand. In the drilling process of the drill rod, the cement-soil spouting pipe pumps cement slurry, the sand blast pipe conveys fine sand at the same time, and the cement slurry, the sand and the stirred foundation soil are stirred together. A certain amount of fine sand is added into the silt clay and the silt stratum to increase the coarse grain content of the foundation soil so as to reduce the plasticity index and improve the pile forming quality and strength of a stirring pile.
Description
Technical field
The present invention relates to the piling method of agitation pile, especially relate to a kind of flabbiness ground strengthened construction equipment and job practices of using with bracing of foundation pit of adding sand cement soil agitation pile.
Background technology
In the prior art, the slurries that cement mixing pile is used are generally neat slurry, but through practice for many years, adopt the cement mixing pile of this neat slurry, and pile quality is difficult for guaranteeing in stratum such as mud matter clay, mud matter, and soil cement intensity is lower.
Summary of the invention
Technical problem to be solved by this invention is, overcomes problems of the prior art, provide a kind of and add sand cement soil mixing pile construction equipment, and the method that adopts this kind equipment to construct.
In order to address the above problem technical scheme of the present invention is such:
A kind of sand cement soil mixing pile construction equipment that adds comprises drilling rod, and drilling rod is provided with the cement-soil shotcrete pipe, it is characterized in that, also is provided with a blast tube that is used for sandblast on the described drilling rod.
Described sand is the powder fine sand, and particle diameter is smaller or equal to 10mm.
A kind of employing the said equipment carries out the mixing pile construction method,
Prepare cement paste, fine sand according to designing requirement;
Start mixing pile machine, in the rod boring whipping process, cement-soil shotcrete pipe pumps water mud, blast tube is also carried fine sand simultaneously, and cement paste, sand, soil are stirred in the foundation soil that stirs;
When arriving projected depth, mention drilling rod and stirring.
In mentioning drilling rod and whipping process, cement-soil shotcrete pipe pumps water mud, blast tube is also carried fine sand simultaneously.
Beneficial effect:
The present invention improves the pile quality and the intensity of agitation pile by add a certain amount of powder fine sand in mud matter clay and mud stratum.Overcome conventional cement mixing method pile difficulty in stratum such as mud matter clay, mud, problems such as pile quality difference.Same formation adopts aforesaid way, carries out cement-soil sandblast mixing pile construction, and the cement mixing method of the strength ratio routine behind the pile improves more than 15%.
