Description
One, technical field
The present invention relates to the building foundation engineering construction machinery---stake machine and construction technology thereof specifically relate to the specific stub machine and the construction technique thereof of concrete core cement soil stirring pile.
Two, background technology
Concrete core cement soil stirring pile is in time to insert the composite pile that forms in the cement mixing method with the little side's stake of prefabricated reinforced concrete.The mid-90, along with the application of concrete core cement soil stirring pile has produced the cement-soil mixing pile machine that installs diesel hammer additional, it is the concrete core cement soil stirring pile machine of the first generation, in fact this machine has just been carried additionally a diesel hammer on the basis of original ripe mixing pile machine, as can be seen from Figure 1, this machine frame is shelved on two mobile transverse tubes, and the displacement of stake machine relies on the main winch pulling of switchbox control, realizes on mobile transverse tube in length and breadth to moving.Drilling cramp is arranged on frame one end, stirs the drill bit vertical ground deeply for guaranteeing that drilling cramp reaches, necessary leveling pile machine frame, and this can only rely on the mobile transverse tube of filling to adjust, and difficulty is bigger.The cycloidal-pin wheel reducer is the power set that stir drilling rod and drill bit deeply, the hammering pile frame is parallel with stake machine frame, be arranged on the drilling cramp outside, diesel hammer is tapped the head by secondary hoist engine pulling injection side's stake, stable for guaranteeing drilling cramp and hammering pile frame, strut is installed on this machine separately, adjusting screw(rod) can be regulated strut length, so that the drilling cramp adjustable height is to be fit to the construction of different depth cement mixing method.
Construction technology: 1. rely on mobile transverse tube, main winch to carry out the pile-forming machine perching centering leveling; 2. stir drilling rod and drill bit deeply and stir sinking in advance; 3. prepare mortar; 4. whitewashing is stirred; 5. stir multiple spray again; 6. along mobile transverse tube sidesway stake machine frame and hammering pile frame, and make the hammering pile frame after moving be positioned at the top of finishing agitation pile; 7. lift by crane prefabricated little side's stake and make little side's stake point aim at the center of agitation pile with secondary hoist engine, the side's of setting upright stake, pile crown puts pile cover, and starting hammering system uses hammering hammering side's stake to desired depth; 8. with sulphide mastic or welding pile extension; 9. repeating step 7., until the construction of finishing whole pile.
This machine can be finished the construction of concrete core cement soil stirring pile substantially, but still exists obviously not enough: 1. because the mobile and smoothing of frame only depends on two mobile transverse tubes, therefore, the verticality on drilling rod and drill bit and ground is subjected to the restriction of ground flat degree bigger; 2. adopt hammering mode injection small bore side's stake, very easily cause the pile crown breakage; 3. owing to lack guiding and stopping means, inserts little side stake verticality and with the very difficult assurance of the axiality of cement mixing method; 4. the noise of hammering generation is unallowed in many occasions.
