Jet grounting Ground Treatment there has been in China and applies widely, and has formulated corresponding working design specification.More and more applied in highway soft ground stabilization, hydraulic engineering antiseepage, mine working reinforcing and antiseepage etc.In some metropolis, along with the emergence of subway construction and highrise building, many deep-foundation pit engineerings also all have employed high pressure jet grouting technique to carry out the sealing antiseepage of deep foundation ditch.High pressure jet grouting can be divided into single tube, double pipe and triple pipe three kinds of methods by Grouting Pipe type.Single tube is with simple jet cement slurries; Double pipe wraps up one deck pressure-air and sprays simultaneously outside cement grout jet, destroys soil layer construction, completes displacement simultaneously, fills; Triple pipe be then wrapped up pressure-air High-Pressure Water to destroy soil layer construction, then carry out replacing, filling with cement grout.
Practice shows, this law is moulded mud, mucky soil, stream or the ground such as soft plasticity cohesive soil has good treatment effect.In Construction of High Pressure Jet Grouting Pile, choosing of various technical indicator is the key affecting engineering construction and quality, and current high-pressure rotary-spray construction technology there has been to be applied more widely.This technology is applicable to containing building waste, rubble, the banketing of jackstone, the sea front of the rich groundwater such as layer of sand, flour sand, silt and have the water-stop curtain construction of location, inland deep-foundation pit engineering of similar soil layer.Common process is difficult to the problem of pore-forming, the final program that adopts is constructed.Common process is difficult to the problem of pore-forming, the final program that adopts is constructed.
Summary of the invention
The present invention, in order to make up the deficiencies in the prior art, provides that a kind of construction noise is little, the impact of friction, formation and surrounding enviroment is little, mechanization of building operation degree is high, the high-pressure rotary jet grouting pile double-jacket tube drilling construction device of easy construction.
The present invention is achieved through the following technical solutions:
High-pressure rotary jet grouting pile double-jacket tube drilling construction device of the present invention, comprise rig, rig is by transmission device jointed rod, it is characterized in that: rig is arranged on chassis, chassis is fixed with drill rod support frame, drilling rod is arranged in drill rod support frame, drilling rod inside is cavity, drilling rod lower end arranges the shower nozzle connecting cavity, drilling rod upper end connects the filling barrel do not rotated by bearing, filling barrel is arranged on drill rod support frame, filling barrel connects three pipelines respectively by each valve, first pipeline connects high-pressure clear water pump, second pipeline connects high pressure slurry pump, 3rd pipeline connects air compressor machine, high pressure slurry pump connects slurry bucket, slurry bucket connects mixer, mixer connects water tank and cement bin, the steel sleeve that high-pressure rotary jet grouting pile double-jacket tube drilling construction device also comprises the hole wall punched for supports drill rods and the PVC wall-protecting shock tube be enclosed within steel sleeve, the aperture that steel sleeve and drilling rod punch matches, and the tube wall of PVC wall-protecting shock tube has a large amount of air vents, rig, high-pressure clear water pump, high pressure slurry pump, air compressor machine are connected PLC respectively with mixer.
The rotary churning pile induration that high-pressure rotary jet grouting pile double-jacket tube drilling construction device of the present invention is made, it is characterized in that: cylindrical, comprise and be from inside to outside arranged in order mutually bonding cement hardener main column layer, cement, foundation soil body and PVC wall-protecting shock tube fragment are uniformly mixed layer, foundation soil body compression layer, and cement permeable formation.
The invention has the beneficial effects as follows, this construction equipment is for high-pressure rotary jet grouting pile waterproof curtain construction process under the geological conditionss such as building waste, and this equipment work noise is little, friction, formation and surrounding enviroment affect little, and mechanization of building operation degree is high, and construction quality is high, easy construction, is beneficial to popularization.Solve the seepage of foundation pit side-wall and the safety issue of construction, there is higher society and environmental benefit.
Follow up by selecting high hydraulic type, double-jacket tube and draw the measure in hole, follow up draw the measure in hole than the high wind pressure type selected in early days, double-jacket tube, speed of fulfiling hole will improve about 20%, improve speed of application, reduce construction cost 4,200,000 yuan, the reduction of erection time, save management fee and equipment leasing expense.
Accompanying drawing explanation
Fig. 1 is high-pressure rotary jet grouting pile double-jacket tube drilling construction device schematic diagram of the present invention.Fig. 2 is rotary churning pile induration schematic diagram.
In figure, 1 rig, 2 drilling rods, 3 chassis, 4 drill rod support frames, 5 shower nozzles, 6 filling barrels, 7 high-pressure clear water pumps, 8 high pressure slurry pumps, 9 air compressor machines, 10 slurry buckets, 11 mixers, 12 water tanks, 13 cement bins, 14 rotary churning pile indurations, 15 cement hardener main column layers, cement, 16 foundation soil bodies and PVC wall-protecting shock tube fragment are uniformly mixed layer, 17 foundation soil body compression layers, 18 cement permeable formations, 19 steel sleeves, 20 PVC wall-protecting shock tubes.
Detailed description of the invention
Accompanying drawing is a kind of specific embodiment of the present invention.
