Description
Technical Field
The utility model relates to a foundation stabilization construction equipment, more specifically say and relate to a cutting slip casting agitating unit.
Background
The cement stirring foundation strengthening is one method of strengthening saturated soft clay foundation, and the cement is used as curing agent, and the cutting, grouting and stirring apparatus is used to forcedly stir cement and foundation soil and the curing agent and the foundation soil produce a series of physical and chemical reactions to form the foundation with integrity, water stability and certain strength. The cutting grouting stirring device forcibly mixes the cement paste pressed into the soft soil with the surrounding soft soil by using a rotating stirring blade to form a mud reinforcing body.
The current cutting grouting stirring device comprises: single axis, double axis, three axis and five axis. The four distinguishing features are that the number and arrangement of auger holes used are different: only one spiral stirring drilling tool is used for a single shaft; the double shaft uses two spiral stirring drilling tools; three spiral stirring drilling tools are used for three shafts, wherein two drilling rods supply slurry, and one drilling rod supplies gas; five spiral stirring drilling tools are used in five shafts, wherein three drilling rods supply slurry, and two drilling rods supply gas.
In essence, cement-mixed foundation stabilization is a cement-mixed reinforcement formed by forcibly mixing cement paste pressed into foundation soil with surrounding foundation soil with a mixing blade of a cutting, grouting and mixing device. In actual construction, spiral uneven reinforcement bodies are formed by ground soil and cement paste cut by a single-shaft and double-shaft cutting and stirring device under the action of a rotating stirring blade, and a gas supply drilling tool added by three shafts and five shafts utilizes the phenomenon that the spiral unevenness of the ground soil and the cement paste is damaged by stirring of compressed gas, so that the uniformity of the reinforcement bodies cannot be completely improved, and the reinforcement bodies are loosened due to trapped gas.
SUMMERY OF THE UTILITY MODEL
The utility model aims to solve the technical problem that a cutting slip casting agitating unit is provided, its technical scheme who adopts is: the utility model provides a cutting slip casting agitating unit, it is including the drill bit pole that is provided with whitewashing passageway and nozzle, arranges the drill bit that has the cutting tool bit of drill bit pole one end in, sets up stirring vane on the drill bit pole, its characterized in that: and a spoiler is also arranged between the drill bit and the stirring blade on the drill bit rod, and moves up and down along with the drill bit rod without rotating along with the drill bit rod.
The utility model discloses further technical characteristic is:
the spoiler comprises spoiler blades, a wear-resistant ring and a rib plate, wherein the wear-resistant ring is sleeved on the drill rod and is in clearance fit with the drill rod.

FIG. 2 is a side view of the embodiment shown in FIG. 1;
fig. 3 is a schematic cross-sectional view of the spoiler of fig. 1.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and embodiments of the present invention.
Referring to fig. 1, 2 and 3, a cutting grouting mixing device comprises a drill bit rod 6 provided with a guniting passage 3 and a nozzle 2, a drill bit 1 with a cutting bit 7 disposed at one end of the drill bit rod 6, and a mixing blade 5 disposed on the drill bit rod 6, wherein: a spoiler 4 is further arranged on the drill bit rod between the drill bit 1 and the stirring blades 5, and the spoiler 4 moves up and down along with the drill bit rod 6 without rotating along with the drill bit rod.
Because the utility model discloses in the cutting slip casting agitating unit still be provided with spoiler 4 between drill bit 1 and stirring vane 5 on drill bit pole 6, spoiler 4 moves up and down along with drill bit pole 6 and does not rotate along with drill bit pole 6, like this in the cutting slip casting stirring process of pushing down, drill bit 1 of cutting slip casting agitating unit kind is rotatory while pushing down, cement thick liquid gets into spouting passageway 3 in drill bit pole 6, then spout through nozzle 2, cutter head 7 on drill bit 1 destroys the foundation soil, in the process that the foundation soil is constantly destroyed, spoiler 4 only pushes down and does not rotate, the fluid flow direction that forms when disturbing the drill bit gyration, make cement thick liquid and foundation soil fully stir the mixture, form the cement soil column mixed liquid of certain diameter in the soil; in the promotion cutting benefit thick liquid stirring in-process, 1 limit antiport of drill bit promotes, the whitewashing passageway 3 that the cement thick liquid got into in the drill bit pole passes through nozzle 2 blowout, stirring vane 5 carries out the secondary stirring to the soil cement column mixture, in the process of 5 continuous stirring of stirring vane, stirring spoiler 4 only promotes not rotatory, the fluid flow direction that forms when disturbing stirring vane 5 gyration, make the cement thick liquid and the abundant stirring of foundation soil mix, form the soil cement column consolidation body of certain diameter in soil, cutting slip casting agitating unit is through pushing down cutting slip casting stirring process and promotion cutting benefit thick liquid stirring process like this, grout can reach the stirring with the foundation soil, thereby the reinforced quality of cement mixing ground has been guaranteed.
