Technical field
This utility model relates to a kind of constructional engineering machinery, particularly relates to a kind of extension bar type deep cement-mixed pile machine.
Background technology
Cement mixing pile is to utilize cement as the host of firming agent, is a kind of effective form for the treatment of of soft foundation, utilizes mixing pile machine cement jet enters the soil body and is sufficiently stirred for, and makes cement, with soil, series of physical chemical reaction occur, and makes weak soil scleroma improve foundation strength.
At present, conventional cement-soil stirring pile construction has the multi-axial such as single shaft, twin shaft, three axles, five axles, in addition with jet grouting pile construction form.The various forms construction technology difference of cement mixing method is little, is all cement mortar is squeezed into stirring maintenance after in weak soil form soil cement, makes cement and weak soil generation series of physical chemical reaction, make weak soil scleroma improve underlying strength.It main difference is that: the cement mixing method of (1) single shaft and twin shaft is action of forced stirring, the stirring that the cement mortar being about to squeeze into carries out at a slow speed with weak soil mixes, its counter productive is that soil compaction effect is big, if periphery exists equipment or it can be caused comparatively serious impact by municipal pipeline；The cement mixing method of (2) three axles and five axles is displaced type stirring, takes the part soil body out of by drilling rod rotary cutting, and the overlap joint of cement mixing method is dependent on repeating set brill and ensures, its pile-forming effect is good, currently also the most frequently used.But the Cement Mixing Pile Construction Technology of above two form all needs the open construction site not having limit for height, general tens meters high of its pile frame drill sting device, when the limited high request in construction operation place, the situation of limit for height such as under high voltage cable as present above in pile foundation or bridge, pile foundation construction will be unable to be normally carried out, and existing measure includes the temporary transient displacement of cable；Resettlement barrier, after to be onstructed, recovery etc. again, necessarily leads to and itself has an increased difficulty and cost to engineering.It addition, when stirring original soil and cement mortar, if power is not enough or speed is little, original soil and cement also stir less fully mixed, therefore, construction effect and inefficient, do not reach construction requirement.
Summary of the invention
The problem that may not apply to the base pit engineering of the limited high request in construction operation place for existing cement mixing pile driving construction, the purpose of this utility model there is provided a kind of can the deep cement-mixed pile machine of extension bar type of low clearance operation, owing to drilling rod can according to lower drilling depth jointed rod standard knot section by section, thus realizing the smooth construction of pile foundation under building-site low latitude, and increase the mixing effect fully mixed of original soil and cement.This utility model not only overcomes the deficiencies in the prior art, it is provided that a kind of extension bar type Deep Mix Column into Supporting machine, and has the advantage that work efficiency is high.
According to this utility model extension bar type deep cement-mixed pile machine, including: Mobile derrick, drill rod mechanism, pressure-air conveying mechanism, power-driven mechanism；Described Mobile derrick, by mobile platform, one-level operating platform, secondary operation platform and jenny composition, brill mouth is offered bottom described one-level operating platform, arranging the jenny of lifting drilling rod on described secondary operation platform, described jenny is made up of arm, motor and cable and is arranged on derrick arm around the rotation of derrick arm；Described drill rod mechanism includes drilling rod and the latch composition of more piece hollow, and described drilling rod two end is made up of male joint and female joint respectively；Described pressure-air conveying mechanism is made up of air compressor machine and appendix, described appendix enters the scope of operation of drill bit by the pipeline of hydraulic power head jointed rod, among press-in original state mud and cement, and when promoting drilling rod, the cement mortar in drilling rod pipeline is emptied；Described power-driven mechanism includes power motor, hydraulic power head and hoisting mechanism, described power motor provides power for described hydraulic power head, described hoisting mechanism is arranged on described Mobile derrick top, chain or cable hang and poise described hydraulic power head.
Preferably, the described brill mouth of described one-level operating platform also sets up two clamps, and described clamp arranges semicircle orifice and is connected with described one-level operating platform by hinge.
Preferably, described power motor is made up of the motor of two high or low powers, described low-power machine provides the power slowly run to drive described drilling rod lifting for described hydraulic power head, and described heavy-duty motor provides high-revolving power to drive drilling rod to act on the scope of operation for described hydraulic power head.
Preferably, the male joint end surrounding of described drilling rod also sets up O RunddichtringO.
Compared with prior art, the beneficial effects of the utility model are: owing to employing hydraulic power head, it is possible to connect the drilling rod of multiple standard component, and therefore, it can lower than 5 meters Mobile derrick design height.In order to operate jointed rod, devise two layer operation platforms and be also provided with crane on the operating board of the second level；In order to make drilling rod be connected firmly, drilling rod uses the joint of male and female, and employs latch；In order to make Soil-cement fully mixed, the stirring scope of operation adds pressure-air and enters in soil cement, decrease cement mortar and original soil frictional force and viscosity, meanwhile, when carrying drilling rod, it is also possible to the pipeline of drilling rod is emptied soil cement；Use two different capacity electromotors, it is possible to provide two different rotating speeds to hydraulic power head, in falling-rising or jointed rod, it is possible to slowly run, in stirring, it is provided that power at a high speed improves stirring efficiency.Due to above design, cement-soil mixing pile machine of the present utility model meets the pile frame of drilling rod height without arranging on the ground, it is possible to realize there is the smooth construction of pile foundation in limit for height situation at the construction field (site).
