Description

CFG stake pile head cutting mount

Technical Field

The utility model relates to a CFG pile head cutting fixing frame.

Background

In the road construction process, in order to make the road more stable and durable, often carry out a foundation's reinforcement to the road through the CFG pile body and make the foundation of road can not be destroyed because of conventional soil is not hard up, the CFG pile body is cement fly ash gravel pile, mix cement by rubble, stone bits, sand, fly ash and add water and mix, variable strength stake that has certain intensity of making with various pile-forming machinery, CFG stake composite foundation passes through the mattress pad layer and is connected with the basis, no matter the stake end falls in general soil layer or hard soil layer, all the time can guarantee that stake soil participates in work. Because the strength and modulus of the pile body are larger than those of the soil between the piles, the stress of the pile top is larger than the surface stress of the soil between the piles under the action of load. The piles can transmit the borne load to a deeper soil layer and correspondingly increase the load borne by soil among the piles. Therefore, the bearing capacity of the composite foundation is improved and the deformation is reduced due to the action of the piles, so that the piles and the soil share the load.

And reserving part of CFG pile bodies to be exposed on the ground in the casting process of the CFG pile bodies, uniformly cutting the CFG pile bodies exposed on the ground to enable each CFG pile to reach a uniform height, and then reinforcing the foundation on the basis of the CFG. After the CFG pile body is cut, partial adhesion exists, the CFG pile body which is cut needs to be manually removed, the conventional removal is carried out by placing an iron cone in a cutting gap and then knocking the iron cone by a hammer, so that the cut CFG pile part is separated from the CFG pile in the foundation, and the plane cut by the CFG pile is trimmed.

Because of the quantity of CFG stake is more, places the required work load of iron awl and increase through the manual work, and the iron awl can rock, the scheduling situation drops at the in-process of strikeing, needs the manual work to place the iron awl in the cutting gap once more, and the space between each CFG stake is limited, and the iron hammer strikes the in-process and can't execute the exhibition completely, has increased the later stage engineering time.
