Description
Technical field
The utility model relates to a kind of double-shaft two-way agitation pile equipment.
Background technology
Reinforce in construction at current existing foundation soil, various construction method is had to implement construction method targetedly with equipment to face, each region, and place material or add chemical agent carry out auxiliary two-way stirring soil to reach pile, gear soil, stagnant water effect, lot of domestic and international enterprise drops into a large amount of funds all one after another with the institution of higher learning and takes which kind of measure can reach best effects with construction speed with equipment with time developmental research soil fixation.Stirring this construction of soil fixation originates from abroad at first, especially in island country, coastal area the most generally uses, it uses single shaft one to stir soil fixation, and because of single shaft, to stir uneven pile-forming effect undesirable, and its main cause is that the blade on drill bit buries towards a direction all the time to pass and turns, pile super helix shape, and interlayer mud is wrapped up in amalgamation and risen again, resistance to compression is low, really undesirable.The soil layer in its area, coastal region is softer, the area even had below sea level 100 meters be all mud cover, directly affects at this area highway, bridge, the construction such as railway, the input of difficulty with increase fund is brought to construction unit, according to the various project demands of construct and design, be not limited to again a kind of construction method, different construction method can be used with equipment according to the situation analysis of the test pile that fetches earth, construct targetedly, and can optimum efficiency be reached, often unit in charge of construction does according to the sampling of design drawing test pile and stirs which kind of construction equipment of taking of soil fixation with method,
It is large for its defect of single shaft agitation pile, and it has welded one group of fixing stirring vane by drilling rod leading portion, and a direction is stirred, and stir uneven, pile body clips earth, again super helix shape, and very difficult control mixes cement soil mixability, and therefore pile is poor, and quality cannot ensure.
Bidirectional stirring pile is characterized in that being that the coaxial relative direction biography that realizes turns above, stirring concrete earth is even, pile-forming effect is good, but shortcoming is, two-way stirring power box is heavy, the patent No. 200410065861.4 of such as national publication mandate or ZL2008 10019933.X belong to single-axis bidirectional and stir, it constructs them and employs two powerful pinwheel cycloids of the same type to drive two-way inside and outside drilling rod, it is suspended on rig pylon heavy, telephone-moving is slow, more can not realize double-shaft two-way and bore lower two pile-type simultaneously, its reason is caused by headstock heaviness, pylon cannot hang two dynamical systems to creep into double-shaft two-way simultaneously and has stirred two overlap joints pile-type side by side, especially going along with sb. to guard him pile-type, to highlight its mobile drilling tool of heaviness slow, inefficiency, all generally have employed two-way stirring in China coast city with road in recent years and do Soft Soil Layer reinforcing, fender post, reaming dowel pin type stake etc., its equipment investment is little, spray pressure is low, material requested cost is low in addition, s' adopt by most of designing unit, be exactly that this equipment is erect higher only, tower suspension systematic comparison is heavy, limit to and drilled double-shaft two-way stirring simultaneously, make construction speed slow, namely add power consumption and turn increase operating expenses.
For the problem in correlation technique, at present effective solution is not yet proposed.
