Abstract
The invention discloses a combined pile toe for a steel pipe pile, and relates to the pile toe of the steel pipe pile of constructional engineering. The combined pile toe is formed by combining a plurality of pile pieces in the same structure, wherein each pile piece comprises an arc-shaped cone plate with a pointed end at the lower end and an arc-shaped hoop plate formed by curving a rectangular steel plate, each arc-shaped cone plate is formed by curving a fan-shaped steel plate, the arc-shaped hoop plate is connected onto the upper end surface of the arc-shaped cone plate, and compared with the lower end surface of the arc-shaped hoop plate, the upper end surface of the arc-shaped cone plate protrudes a part inwards; lock lugs are arranged on the upper end surface of the arc-shaped hoop plate, and a lock shaft hole is formed in each lock lug; each pile piece is connected with each flexible lock shaft, so that the pile toe is formed, each pile piece is fixed at the pile end of the steel pipe pile, the arc-shaped hoop plate of each pile piece is surrounded to form a casing pipe, and the casing pipe tightly hoops the periphery outer wall of the pile end of the steel pipe pile; the lower end surface of the steel pipe pile is supported on the upper end surface of the arc-shaped cone plate of each pile piece, and after the pile toe is combined by the arc-shaped cone plate of each pile piece, a cone is formed. The combined pile toe disclosed by the invention is easy to assemble and convenient to mount, the construction quality is ensured, the workload of mounting the pile toe on site can be greatly reduced, and pollution and noise are not generated.
Description
Technical field
The present invention relates to a kind of pile top of construction work steel pipe pile, be specially a kind of steel pipe pile combined type pile top.
Background technology
Pile foundation is the basis being widely used in hydraulic engineering, bridge engineering, industry and civilian construction etc.The kind of stake is a lot, divides common are reinforced concrete pile and piling bar by material; Divide by construction technology and have castinplace pile and preformed pile etc., preformed pile has precast reinforced concrete piles and piling bar, and steel pipe pile belongs to a kind of pile-type of preformed pile.The work progress of existing steel pipe pile is: the steel pipe pile designed and produced is transported to job site, be driven into smoothly in order to steel pipe pile can be made or be pressed in soil layer, scene is needed to process the stake end of steel pipe pile, namely pile top is welded on stake end by on-site cutting steel plate, then stake sling with loop wheel machine, align piles position, to squeeze into stake with stake machine or during static pressure buries, when pile top enters design elevation place in bearing stratum, namely stop piling or static pressure.The pile top of existing structure need be welded on steel pipe pile stake end, and for the pile foundation that engineering pile quantity is larger, its workload is very large, and labour intensity is very high, and produces a lot of noise, and the welding quality of stake end and pile top is wayward, affects pile foundation quality.
Summary of the invention
The object of this invention is to provide a kind of steel pipe pile combined type pile top, its assembling is easy, easy for installation, ensures construction quality, can greatly reduce on-the-spot pile top installation workload, reduces working strength, and does not produce pollution and noise.
For achieving the above object, technical scheme of the present invention is: a kind of steel pipe pile combined type pile top, combined by multiple mutually isostructural stake lobe, each lobe comprises a cuspidated arcuation cone-plate of the lower end band curled into by fan-shaped steel plate and an arcuation hoop plate curled into by rectangular steel plates, arcuation hoop plate is connected on the upper surface of arcuation cone-plate, and the upper surface of arcuation cone-plate compared with the lower surface of arcuation hoop plate to a projecting inward part, the upper surface of arcuation hoop plate is provided with lock ear, lock ear is provided with lock shaft hole, each stake lobe synthesizes pile top by a flexible lock shaft Connecting groups and is fixed on the stake end of steel pipe pile, the arcuation hoop plate of each stake lobe surrounds into a sleeve pipe lock ring in the outer circumferential walls of steel pipe pile stake end, steel pipe pile lower surface is supported on the upper surface of each stake lobe arcuation cone-plate, the arcuation cone-plate of each stake lobe is combined into after pile top in coniform.
Beneficial effect: pile top of the present invention is combined by multiple lobes, it adopts a flexible lock shaft to be coupled together by each stake lobe, and the pile top that multiple lobes can be combined into tightly latches in the stake end of steel pipe pile, this assembling process easily carries out, pile top is easy for installation, greatly reduce on-the-spot pile top installation workload, and can construction quality be ensured.The stake end of steel pipe pile is supported on a upper surface of lobe arcuation cone-plate, can cushion the soil layer counter-force in piling process suffered by steel pipe pile like this, reduces the destruction probability of steel pipe pile.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention.
Be labeled as in figure: 1, arcuation cone-plate, 2, arcuation hoop plate, 3, lock ear, 4, lock shaft hole, 5, flexible lock shaft.
Detailed description of the invention
As shown in Figure 1, a kind of steel pipe pile combined type pile top, combined by multiple mutually isostructural stake lobe, the number of stake lobe can be three or four etc., each lobe comprises a cuspidated arcuation cone-plate 1 of the lower end band curled into by fan-shaped steel plate and an arcuation hoop plate 2 curled into by rectangular steel plates, arcuation hoop plate 2 is connected on the upper surface of arcuation cone-plate 1, and the upper surface of arcuation cone-plate 1 compared with the lower surface of arcuation hoop plate 2 to a projecting inward part, projection is for being supported on the below of steel pipe pile stake end lower surface, in concrete enforcement, the thickness of the steel plate of making arcuation hoop plate 2 can be made to be less than the thickness of the steel plate making arcuation cone-plate 1, and the lower surface of arcuation hoop plate 2 and the upper surface of arcuation cone-plate 1 are linked together, the crooked radian of arcuation hoop plate 2 is identical with the crooked radian of arcuation cone-plate 1 upper surface.The upper surface of arcuation hoop plate 2 is provided with lock ear 3, lock ear 3 is provided with lock shaft hole 4, each stake lobe synthesizes pile top by flexible lock shaft 5 Connecting groups and is fixed on the stake end of steel pipe pile, the arcuation hoop plate 2 of each stake lobe surrounds into a sleeve pipe lock ring in the outer circumferential walls of steel pipe pile stake end, steel pipe pile lower surface is supported on the upper surface of each stake lobe arcuation cone-plate 1, and the arcuation cone-plate 1 of each stake lobe is combined into after pile top in coniform.Wherein, each stake lobe links together and is combined into pile top by the lock shaft hole 4 that flexible lock shaft 5 passes each stake lobe, and making arcuation hoop plate 2 lock ring of each stake lobe in the outer circumferential walls of steel pipe pile stake end, two ends of flexible lock shaft 5 lock together thus pile top and steel pipe pile are linked together.When piling or pressing pile construction, each stake lobe of pile top is in closure state under external force.Stake lobe of the present invention and lock shaft can process in batch in processing factory, and the size according to engineering pile quantity is transported to job site, carry out assembling, easy to use.
