Abstract
The invention relates to a jet grouting and stirring drill tool used for anchoring construction on soil mass. The drill tool comprises a drill bit, wherein the rear part of the drill bit is in a bell and spigot joint or a fixed connection with one end of a hollow drill stem, and the side wall of the hollow connecting stem is distributed with jet holes; an annular drill stem disk is fixed on the front stem body of the drill stem, and the side of the drill stem disk facing towards the drill bit is provided with drill stem disk protrusions; one end of an anchoring bar is fixed on an annular anchored plate through an anchor head; the drill bit and the drill stem pass through a hole in the center of the annular anchored plate; and the protrusions on the drill stem disk are in socket joints with corresponding pits on the anchored plate.
Description
Technical field:
The present invention relates to a kind of jet grouting and stirring drill tool that is used for soil body anchoring construction.
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 is directed to above-mentioned difficulties and design a kind of soil body anchoring jet grouting and stirring drill tool that is used for, utilize this drilling tool construction can effectively improve anchoring construction the soil body.
Summary of the invention:
The object of the present invention is to provide a kind of jet grouting and stirring drill tool that is used for soil body anchoring construction.This drilling tool comprises drill bit; The rear portion of this drill bit is connected with an end socket joint of hollow drill; This hollow drill inserts the front end sealing of drill bit; Be distributed with spray-hole on the sidewall of this hollow drill, the forward bar of drilling rod is fixed with the drilling rod dish of annular on one's body, and the drilling rod dish has drilling rod dish convexity to a side of drill bit.One end of dowel is fixed on the anchor ingot plate of annular through anchor head, and drill bit and drilling rod pass the hole at annular anchor ingot plate center, corresponding pit bell and spigot joint on convexity on the drilling rod dish and the anchor ingot plate.Several Fixing shrink rings are crossed drilling rod and each bar dowel are tied up solid on retainer ring.
The maximum gauge of drill bit should be more than or equal to the external diameter of anchor ingot plate.A drilling rod dish side of drill bit dorsad will be processed ramped shaped, to make things convenient for extracting of drilling rod.
Description of drawings:
Fig. 1 is the sectional drawing of jet grouting and stirring drill tool.
Wherein, 1-three leaf drill bits, the 2-hollow drill, the 3-dowel, the 4-anchor head, 5-drilling rod dish, 6-drilling rod dish is protruding, 7-anchor ingot plate, 8-retainer ring.
The specific embodiment:
Drilling tool comprises drill bit; The rear portion of this drill bit is connected with an end socket joint of hollow drill, and this hollow drill inserts the front end sealing of drill bit, is distributed with spray-hole on its sidewall; The forward bar of drilling rod is fixed with the drilling rod dish of annular on one's body, and the drilling rod dish has drilling rod dish convexity towards a side of drill bit.One end of dowel is fixed on the anchor ingot plate of annular through anchor head, and drill bit and drilling rod pass the hole at annular anchor ingot plate center, corresponding pit bell and spigot joint on convexity on the drilling rod dish and the anchor ingot plate.Several Fixing shrink rings are crossed drilling rod and each bar dowel are tied up solid on retainer ring.
When drilling rod is connected with the drill bit socket joint; Bit drills is gone in the soil body process; Through high-pressure slip-casting equipment soil body injection towards periphery cement grout; Cement grout mixes with the soil body of being done pine by drill bit on every side and makes this position soil body obtain reinforcing through the soil body penetration of self pressure around the soil body of doing pine, when drill bit gets into the precalculated position, extracts drilling rod; At this moment drill bit and anchor ingot plate and the dowel that is fixed on the anchor ingot plate are left in the soil body, simultaneously along with extracting of drilling rod continued the high-pressure injection cement paste to plug the gap and dowel is carried out anchoring.
The maximum gauge of drill bit should be more than or equal to the external diameter of anchor ingot plate.A drilling rod dish side of drill bit dorsad will be processed ramped shaped, to make things convenient for extracting of drilling rod.
