Abstract
A long spiral drilling screw pile pile-making device belongs to concrete pile construction equipments, a two-way cylinder is arranged in horizontal direction in a drill rod, a slide track is fixedly arranged on a helical blade and a thread forming device which is inserted in the slide track is articulated with a cylinder rod of the two-way cylinder, after the drilling machine completes the pile pore-forming process, the device lifts the drill rode, simultaneously disposal completes the thread groove process on the lateral wall of the pile hole and concrete bottling, then the screw pile is generated, the utility model has the advantages of simple structure, compound and continuous operation, reliable operation, great quality of pile generation, high operation efficiency and broad applicability and is especially suitable for the operation of underwater or difficult pore-forming field.
Description
Technical field
The utility model belongs to the concrete pile construction equipment, relates generally to concrete screw thread piling machinery.
Background technology
At present, concrete helical burr ram pile forming machine mainly contains two types, a kind of is to install screw thread processing component not removable and that regulate on drilling rod, utilize machinery that the screw thread processing component is screwed in the hole wall soil body, need oppositely back-out then, this equipment requires complicated in the use to the interlock of drilling depth and rotation control, and resistance is big when being screwed into the soil body, the pile difficulty, stake is long to be subjected to certain limitation with the stake footpath.Another kind is the special screw thread shaped device, it is at long-spiral drilling machine in advance behind the pore-forming, descend in the hand-hole secondary to finish screw thread processing again, obviously, two kinds of construction equipments, twice manufacturing procedures make that speed of application slows down, production efficiency reduces, constructs and purchases the machine cost and improves.
Summary of the invention
The purpose of this utility model is exactly problem and the defective that exists at prior art, design provides a kind of long-spiral drilling machine screw-thread piling apparatus, reaches the purpose that simplification operation procedure and operation required, improved operating efficiency, reduction operating cost, enlarge the scope of application.
Basic design of the present utility model is, the two-way cylinder horizontal direction is installed in the drilling rod, and slideway is packed on the helical blade, and the inserting of thread forming device is in slideway, the cylinder rod of thread forming device and two-way cylinder is hinged, and so far constitutes the long-spiral drilling machine screw-thread piling apparatus.
The utility model is after finishing the processing of pile foundation pore-forming, when promoting drilling rod, disposablely on the sidewall of stake hole, form thread groove, and can be synchronously to concrete perfusion at the bottom of the hole, in the hole and in the thread groove, once become the screw thread cast-in-place concrete pile, one platform equipment can disposablely be finished pore-forming, become the whole operations of screw thread, have simple in structure, continuous multiple operation, reliable operation, operating efficiency height, good, the advantage of wide range of application of pile quality, especially be fit under water or be difficult for the operation of pore-forming region and use.
Description of drawings
Fig. 1 is a long-spiral drilling machine screw-thread piling apparatus general structure schematic diagram;
Fig. 2 is the A-A sectional drawing among Fig. 1, i.e. screw thread blade, slideway, thread forming device assembly structure schematic diagram.
Piece number explanation among the figure:
1, drilling rod, 2, helical blade, 3, two-way cylinder, 4, slideway, 5, thread forming device, 6, drill bit, 7, valve.
The specific embodiment
Below in conjunction with accompanying drawing the utility model optimum implementation is described in detail.The long-spiral drilling machine screw-thread piling apparatus comprises drilling rod 1 and is fitted in helical blade 2, drill bit 6 and valve 7 on the drilling rod 1, two-way cylinder 3 horizontal directions are installed in the drilling rod 1, slideway 4 is packed on the helical blade 2,5 insertings of thread forming device are in slideway 4, and thread forming device 5 is hinged with the cylinder rod of two-way cylinder 3.
When operation is used, utilize the long-spiral drilling machine boring that is being equipped with the helical burr ram pile making device, casting to projected depth, two-way cylinder 3 is being pushed out to thread forming device 5 outside helical blade 2 spaces on the slideway 4, and thrusts in the hole sidewall soil body; Carry the long screw auger tool with rig boring equidirectional rotary drill rod and synchronously, the extruding of sliding forms thread groove to the hole wall soil body by the pitch of setting and lead angle on hole wall to make thread forming device 5, simultaneously, by rig central tube and valve 7 at the bottom of the hole, in the hole with thread groove in perfusion filling concrete become helical burr ram; Pile stops the long-spiral drilling machine drilling rod and rotates to the aperture, and two-way cylinder 3 bounces back to thread forming device 5 in helical blade 2 spatial dimensions, treats next hole operation.
