Technical field
The utility model relates to the pile-forming equipment that develops that uses in industry and the domain engineering constructions such as civilian construction, hydraulic engineering, highway, railway and port works, and the shaped pile that special-shaped friction pile that particularly a kind of cross-sectional area is little, external surface area is big and end hold friction pile develops pile-forming equipment.
Background technology
At industry and civilian construction, hydraulic engineering, highway, in the construction of domain engineering such as railway and port works, it mainly is to rely on the side surface of stake and the frictional force of foundation soil that bearing capacity is provided that friction pile or end hold friction pile, the pile-forming equipment that develops that existing preparation friction pile or end hold friction pile mainly comprises the immersed tube of being with charging aperture, free reciprocal post hammer in immersed tube, immersed tube back-pressure device, main winch and secondary hoist engine, immersed tube hangs on the secondary hoist engine wire rope, immersed tube back-pressure device is connected with secondary hoist engine, block stamp hangs on the wire rope of main winch, carrying out the post hammer by alternate repetition develops, immersed tube sinks, form a stake hole, inject concrete material from the charging aperture of immersed tube and promptly form stake.The present cross section that develops its immersed tube of pile making device is generally circle, rectangle or square, the cross-sectional area of the stake that therefore makes also is circle, rectangle or square, because this stake side surface area is less, also big inadequately with the frictional force of foundation soil, the supporting capacity of single pile is restricted.In order to improve side surface frictional resistance and end load, to have to the length of stake is prolonged, or increase the quantity that lays out pile, the increase of the long and stake quantity of stake has improved the cost and the cost of engineering.In addition, its block stamp of existing pile-forming equipment is a column, so impact resistance is big, and impact energy is little, and pile efficient is low, can not form large diameter pile, than hardpan pore-forming difficulty.
The utility model content
Main purpose of the present utility model is to provide a kind of shaped pile to develop pile-forming equipment at the problems referred to above, adopt this equipment can obtain to increase the shaped pile of side surface area, thereby can increase the side surface of stake and the frictional force of foundation soil, and then improve the supporting capacity of single pile; This equipment impact resistance reduces, impact energy increases, and pile efficient improves, and can form large diameter pile.
The design philosophy that the utility model solves its technical problem is on the prior art basis, change the shape of cross section of immersed tube, block stamp, prolong the unit section girth, thereby change the profile of stake, make that its friction surface is long-pending to be increased, the monnolithic case that will have block stamp simultaneously now is changed into streamlined, to reduce resistance, improve impact energy, concrete technical scheme is:
A kind of shaped pile develops pile-forming equipment, mainly comprise immersed tube, block stamp, immersed tube back-pressure device, main winch and the secondary hoist engine of being with charging aperture, immersed tube hangs on the secondary hoist engine wire rope, immersed tube back-pressure device is connected with secondary hoist engine, block stamp hangs on the wire rope of main winch, it is characterized in that described immersed tube is that cross section is the special-shaped immersed tube of how bent limit shape, described block stamp be shape of cross section identical with the immersed tube cross-sectional profile the streamline set hammer.
Described how bent limit shape is approximate X-shaped, approximate Y shape, approximate five-pointed star shape or approximate hexapetalous flower shape.
Described streamline set hammer comprises peen end and fairing two parts, and the fairing external surface is fixed with many to the bottom surface and the identical bar shaped hammer wing of its profile from the fairing top.
The fairing bottom surface fixedly connected grab bucket mechanism of described streamline set hammer.
The beneficial effects of the utility model are: because the immersed tube of pile-forming equipment is developed in the abnormity stake that provides is that cross section is the special-shaped immersed tube of how bent limit shape, its side surface of shaped pile that makes with this equipment is many curve forms, therefore, compare with existing cylinder, square, cuboid stake, the unit section girth increases, under same pile body volume conditions, can obtain largest optimization pile body side surface area, thereby can improve the supporting capacity of single pile; In addition, block stamp be shape of cross section identical with the immersed tube cross-sectional profile the streamline set hammer, with existing column hammer relatively, its resistance is little, impact force is big, therefore the impact energy height can improve pile efficient; Especially to larger-diameter stake, streamlined hammer tip portion has grab bucket, impact squeezed in, grab out a heart position part soil body, the penetration resistance of impact resistance that reduces to hammer into shape and shaped pile immersed tube helps forming larger-diameter stake hole, therefore can form large diameter pile.The utility model extensively model is applied to stratum such as weak soil, saturated soil and silt; Be suitable for industry and fields such as civilian construction, hydraulic engineering, highway, railway and port works.
