The CFG pile cutting machine comprises a rack, a handrail, a water tank, motors, motor reinforcement steel plates, a universal wheel, belts, rotating shafts, cutting blades, rope tying rings and a water tank base plate, wherein the two motors are installed on the rack through the motor reinforcement steel plates which are respectively fixed at the two sides of the rack, the rotating shafts and the rope tying rings are respectively fixed on the two front arms of the rack, the rotating shafts are respectively connected with the motors which are arranged at the same sides of the rotating shafts through the belts, the two cutting blades are respectively installed on the two rotating shafts at the same level, the water tank base plate and the handrail are also fixed on the rack, the water tank is fixed on the water tank base plate, and the universal wheel is installed at the bottom of the rack. The CFG pile cutting machine has large cutting depth and small influence to a pile, the cutting surface is vertical to the pile and is smooth, operators and time are saved, and the construction efficiency is improved.

Description

The CFG stake cuts a machine

Technical field

The utility model belongs to CFG pile construction technology field in the Base Consolidation Engineering, is specifically related to the CFG stake and cuts a machine.

Background technology

CFG stake full name is a CFG, mainly by rubble, aggregate chips, flyash, mixes an amount of cement and water and mixes and stirs the stake of formation high viscosity intensity.

In recent years, the CFG stake railway, highway and, engineering foundation such as Fang Jian adopts by a large amount of in handling.During the CFG pile driving construction, for guaranteeing the construction quality of pile body, generally with the ultra filling amount of the compound 50cm of CFG stake, concrete needs the ultra part of irritating of CFG stake is carried out amputation after reaching design strength.

The piling method that cuts common in the on-the-spot CFG pile driving construction has two kinds:

Using the wedge shape drill rod laterally to cut a hole an eye splitting simultaneously from the both sides of stake strikes off; With small-sized pneumatic pick pile crown is repaired smoothly, with the angle grinding machine pile crown is polished then, this method pile crown fracture is irregular; The fracture of out of plumb pile body very easily appears; The pile body damage range is big, and section is rough and uneven in surface, and pile crown polishing finishing and cleaning to abolish concrete workload very big;

Use the hand-held type miniature cutting machine along pile crown being cut all around; Utilize joint-cutting laterally to cut a hole a splitting with drill rod and strike off, with the angle grinding machine pile crown is polished then, the section rule that this method is broken off than first method; Shortcoming is that penetraction depth is not enough; Generally be merely about 5～10 cm, cut channel remains irregular section with interior, and cleaning to abolish concrete workload very big.

More than two kinds of methods when using drill rod cutter eye to make splitting, need laterally impact, the excessive or impact force off normal of impact force is prone to cause the pile body shallow faults, simultaneously, these two kinds of methods are main with the artificial construction, it is more to expend man-hour, efficient is lower.

Summary of the invention

The utility model is to be prone to cause the pile body shallow faults in order to solve when existing CFG stake cuts, and it is more to expend man-hour, inefficient problem, and provide the CFG stake to cut a machine.

The utility model is realized through following technical scheme:

The CFG stake cuts a machine; Comprise frame, handrail, water tank, motor, reinforcing motor steel plate, universal wheel, belt, turning cylinder, cutting blade, fasten rope annulus, water tank backing plate; Wherein two motors is installed on the frame through the reinforcing motor steel plate that is separately fixed at the frame both sides, is fixed with turning cylinder on two forearms of frame respectively and fastens the rope annulus, and turning cylinder is connected with the motor of homonymy through belt respectively; Two turning cylinders are equipped with cutting blade on same level; Also be fixed with water tank backing plate and handrail on the frame, water tank is fixed on the water tank backing plate, and the frame bottom is equipped with universal wheel.

During use, excavate the CFG pile crown, tamp smooth substrate, measure the lofting Design height of pile top; And will design height of pile top and eject along pile crown with the line of ink marker, the place mat steel plate is as job platform; And an adjustment section stake machine, 1 operating personnel slowly aims at the line of ink marker with cutting blade and promotes, and the frame forearm is provided with fastens the rope annulus; For guaranteeing smooth cutting, 1 operating personnel spur the rope that the frame forearm fastens on the rope annulus and come the controlling level cutting angle, around the CFG stake, rotate suitable angle; Hoop cutting pile crown is fixed rope, pulling rope controlling level cutting angle, and the saw blade temperature is too high when preventing to cut pile crown; The plastic flexible pipe drainage through two diameter 1cm of the water of steelframe upper water box to saw blade, is reached the purpose of cooling.

Further, described motor power (output) is 5.5KW.

In order to verify the performance of the utility model, utilize three kinds of methods respectively same CFG stake to be handled, result is following;

Adopting the wedge shape drill rod laterally to cut a hole an eye splitting simultaneously from the both sides of stake strikes off; With small-sized pneumatic pick pile crown is repaired smoothly, the method for with the angle grinding machine pile crown being polished then on-the-spot cut stake and is needed 2 people cut stake, 1 people's chipping stake top, 2 people polishing; Cutting the average time of the every pile of stake (contain the flat substrate of rammer, cut, polish, clear up pile crown) is 16 minutes; The pile crown fracture is irregular, the fracture of out of plumb pile body very easily occurs, and the pile body damage range is big; Section is rough and uneven in surface, and pile crown polishing finishing and cleaning to abolish concrete workload very big;

Adopt the hand-held type miniature cutting machine along pile crown being cut all around; Utilizing joint-cutting laterally to cut a hole a splitting with drill rod strikes off; The method of with the angle grinding machine pile crown being polished then on-the-spot cut stake and is needed 1 people's ring cutting, 2 people to cut stake, 1 people's chipping stake top, 1 people polishing, and cutting the average time of the every pile of stake (contain ram flat substrate, cut, polish, clear up pile crown) is 12 minutes; Penetraction depth is not enough; Cut channel remains irregular section with interior, is prone to cause a top discontinuity, and cleaning to abolish concrete workload very big;

Utilize the utility model, on-the-spot cut that stake only needs 2 people operation to cut a stake machine, 1 people's brittle failure pile crown can be accomplished, just can cut a pile crown (contain ram flat substrate, pading plate, pile crown cut and the brittle failure pile crown) in comprehensive average per 5 minutes.

Compared with prior art, the utility model depth of cut is big, can reach 15～20cm, and is little to the pile body influence; Cutting the stake back is whole pile crown, does not need to clear up once more to cut pile crown; Cut surface can directly be used for detecting perpendicular to pile body and surfacing, has saved the operation that cuts pile crown and polishing pile crown; Save operating personnel, save the engineering time of every pile, effectively improve efficiency of construction.
