Device, drill rod assemblies, headstock and fast connector；The upper end of drill rod assemblies is connected through headstock with current divider；Current divider with
Outside high-pressure pump connects with air compressor；Drill rod assemblies include drilling rod and are arranged on the drill bit of drilling rod bottom, and drilling rod is double
Bar is redrilled, the bottom of the inner tube of drilling rod is provided with the nozzle of connection internal tube, the position of the bottom corresponding nozzle of the outer tube of drilling rod
Install and be equipped with valve, nozzle extends to outside pipe through valve, and the opening of valve is more than the external diameter of nozzle, high-pressure pump conveying
Highly pressurised liquid is pressed into inner tube through current divider, and the compressed air of air compressor conveying is pressed between inner tube and outer tube through current divider
Annular space in, drill rod assemblies are driven by drive component in headstock and rotated, and fast connector is fixedly connected on power
The side of case is fixedly connected on unit head is solidified on excavator body；Using above-mentioned operation excavator to curing agent mixed liquor and
The method that riverway sludge is mixed, comprises the following steps：
Excavator ontology-driven solidification unit head is moved to river course section to be mixed, and driving solidification power head erect, which down moves, to be stretched
Enter in riverway sludge；
High pressure pump startup, it is pumped into after curing agent mixed liquor is pressurizeed in solidification unit head；
Solidification unit head is driven by drive component to be rotated when down moving, and the curing agent mixed liquor after pressurization sprays from nozzle
Go out, until reaching the mud depth described in step 2；
Air compressor starts, and compressed air sprays from valve, expands the face that curing agent mixed liquor is stirred with riverway sludge
Product.
The present invention has the advantages that：
The technique of the present invention is injected directly into riverway sludge by using the curing agent mixed liquor of liquid in a manner of high-pressure rotary-spray,
Curing agent mixed liquor is mixed to form with water before contacted with mud in curing agent first, is eliminated and dry powder is spilt in common process is caused
Proportioning it is inaccurate, curing agent dry powder spreads the problem of uneven, while greatlys save the dosage of curing agent；
Secondly, curing agent mixed liquor directly can be sprayed into river course on the coast using the operation excavator of the solidification unit head with churning
In the mud at scene, on the one hand, without carrying out operation at sea, on the other hand, can directly carry out consolidating for mud at river course scene
Changing, being handled without will be gone again after mud conveying disembarkation, time saving and energy saving, curing efficiency is high；
Furthermore conventional consolidate is being realized toward the curing agent mixed liquor that pressurization is sprayed into riverway sludge by the way of the high-pressure rotary-spray
While agent mixes with mud, the dissection using high-pressure rotary-spray to riverway sludge, the efficiency of stirring is further increased,
Facilitate the progress and completion of curing process.
