But this technology still exists some shortcomings and defective when practical application, promptly when tubular pile concrete is poured into a mould, at first need to adopt artificial small handcart that site mixed concrete is poured in the winding type concrete charging car, then the lifting of concrete charging car one car one car is poured in the feed hopper on bilayer sleeve top, the pouring concrete construction time has accounted for 70% of bore forming.This material-uploading style is very backward, not only wastes a large amount of manpowers and engineering time, has a strong impact on construction speed, incurs loss through delay the engineering delivery time, simultaneously, concrete transport at the scene with lifting process in unrestrained on-site, construction environment has been caused very big pollution.Though apparently, be not much problems, tight in time requirement, the tight constructing operation aspect that engineering quantity is big, site operation is closely linked often just delays whole engineering construction with regard to these unremarkable indispositions.
In order to address this problem, one of way of trial is to adopt commercial concrete, and the concrete that will stir in factory is transported to the scene with the commercial concrete car, uses the vehicular hydraulic means then, and concrete pressure is transported in the feed hopper.But commodity in use concrete cost is too high, even per ton cost rises a bit, for the huge road of engineering quantity, municipal construction, gathering together is exactly a huge expense, and basic or impossible large tracts of land adopts; Simultaneously, because it is generally all very poor to reinforce the weak soil condition in place, commercial concrete car difficulty reaches building-site, even behind the arrival building site, because the concrete amount that every pile needs is limited, the blanking time long (general about 1 hour) of adjacent two piles construction, cause the concrete sedimentation time in the commodity car long, so need to stir repeatedly, increase cost.
Therefore, at this complicated problems not, the constructor feels simply helpless, and is stymied by, and knows defectiveness perfectly well, also can only construct according to conventional method, makes a large amount of time consumptions on this.According to statistics, such engineering, only this individual event spent time of construction has accounted for more than 70% of whole engineering.
