Abstract
The invention relates to a jet mixing drilling tool and a method with the same for carrying out a soil mass supporting construction. The jet mixing drilling tool comprises a drilling head, the rear part of the drilling head is connected with one end of a hollow connecting rod, an anchor plate is fixed on a side wall of the hollow connecting rod, an anchor bar penetrates through the anchor plate and is anchored on the anchor plate through an anchorage device, the other end namely the rear end of the hollow connecting rod is connected with the front end of a hollow drilling rod in a separable way, and a channel in the hollow drilling rod is communicated with the channel in the hollow connecting rod. The construction method comprises the following steps: excavating the soil mass to the design depth, and constructing a jet mixing reinforcing body in the diagonal direction and the horizontal direction to form a gravity supporting structure, i.e. a retaining wall.
Description
Technical field:
The present invention relates to a kind of rotary jet stirring sprays drilling tool and carries out the method for soil body supporting construction with it.
Background technology:
At the soil body is the loosening sand layer of littoral facies, river facies, mud matter soft layer, alluviation, and the support technology safety of supporting in conventional drilled pile adds is low, and the cost height has pollution to environment.The present invention proposes a kind of new supporting method and construction tool solves the problems referred to above.Drilling tool of the prior art is removed drill bit and is also had stirring vane outward, and having increased resistance and its solid compactness that adds to formation of creeping into influences also little.
Summary of the invention:
The object of the present invention is to provide a kind of rotary jet stirring injection drilling tool and carry out the method for soil body supporting construction with it, the characteristics of this method are that speed of application is fast because rotary jet stirring is sprayed drilling tool is that umbrella shape and taper are inserted easily, at the bottom of the cost, pollution-free and tension dials the power height.
This method method comprises the steps: by the excavation soil body to projected depth, progressively carries out oblique, level in the process and adds solid to applying rotary jet stirring, forms gravity supporting and protection structure, just retaining wall.Before hollow connecting rod is extracted, therein gravity retaining wall is carried out joint bar, make joint bar become easy like this.Can make the retaining wall of rectilinear, horizontal many rows formula gravity.The slurries that use in the described job practices add a spot of chemical agent as cement paste.
Described rotary jet stirring is sprayed drilling tool, comprise drill bit, the rear portion of this drill bit is connected with an end of hollow connecting rod, be fixed with anchor ingot plate on the sidewall of this hollow connecting rod, dowel passes this anchor ingot plate, is anchored on the above-mentioned anchor ingot plate other end of this hollow connecting rod by ground tackle, be that the rear end releaseably is connected with the front end of hollow drill, the channel connection in passage in the above-mentioned hollow drill and the hollow connecting rod.

The specific embodiment:
Carry out excavation of foundation pit according to designing requirement, use rotary jet stirring to spray drilling tool in the digging process and progressively the hole wall is carried out oblique, level and add solid, form gravity supporting and protection structure, just retaining wall to applying rotary jet stirring.After rotary jet stirring injection drilling tool is drilled into the precalculated position, in its hollow stem, insert joint bar, continue the injection pressure slurries while extract hollow connecting rod then.Can make the retaining wall of rectilinear, horizontal many rows formula gravity.The slurries that use in the described job practices add a spot of chemical agent as cement paste.
Claims (3)
1. a rotary jet stirring is sprayed drilling tool, by drill bit, hollow drill, hollow connecting rod is fixed on the outer anchor ingot plate of hollow drill, passes the dowel of this anchor ingot plate and forms, it is characterized in that, dowel is anchored on the above-mentioned anchor ingot plate, and hollow connecting rod is connected in the mode that can throw off with hollow drill, and there is spray-hole the hollow drill end.
2. a method of using drilling tool according to claim 1 to carry out soil body supporting construction is characterized in that comprising the steps:
A), utilize rotary jet stirring to spray drilling tool and add solid to applying rotary jet stirring in oblique, level by the some position of the excavation soil body to design;
B) drilling tool inserts joint bar by hollow connecting rod and hollow drill after creeping into projected depth;
C) extract hollow connecting rod, when extracting, still continue pressure and inject slurries by its boring.
3. the described job practices of root a tree name claim 2 is characterized in that, the slurries that use are as adding a spot of chemical agent in the cement paste.
