Abstract

The utility model discloses a cross thin wall immersed tube equipment of a shaking immersed tube pile puller. The immersed tube equipment consists of a tube body and a flapper picket, the tube body is articulated with the cross flapper picket, the cross section of the tube body takes the shape of a crisscross. When using a cross thin wall concrete pile to reinforce a soft groundwork, firstly, the cross immersed tube equipment is arranged on the shaking immersed tube pile puller and is immersed into the soft groundwork in a wedged way, until reaching the design depth, and then the concrete is poured into the cross thin wall immersed tub, and at the same time, shakes the immersed tube and pulls out the immersed tube, until forming the whole cross thin wall concrete pile. The utility model has the advantages of that compared with the present solid column pile, the bearing capacity of the unit cubage pile of the cross thin wall concrete pile poured by the utility model can be improved by 20 percent to 30 percent, and the construction cost of the soft groundwork reinforcing can be greatly reduced.

Description

A kind of cross thin-walled pipe-sinking device that shakes the tube-sinking cast-in-situ pile machine

Technical field:

The utility model relates to the tube-sinking cast-in-situ pile machine, more specifically relates to the pipe-sinking device of vibrations tube-sinking cast-in-situ pile machine, is used to pour into the stake of cross thin wall concrete.

Background technology:

Strengthening soft foundation adopts tube-sinking cast-in-situ pile mostly at present, can be divided into vibrations tube-sinking cast-in-situ pile, hammer hidden pipe caisson pile and static-pressure driven cast-in-place pile by its hole forming method.When utilizing the tube-sinking cast-in-situ pile strengthening soft foundation, be with vibrations immersed tube pile driver, or hammer hidden pipe pile driver or static pressure, immersed tube pile driver, to have flapper-type stake point or taper respectively and seal the stake point, or the steel pipe of band precast reinforced concrete pile point sinks in the soil, and steel pipe is extracted and the castinplace pile that forms in vibrations of limit concrete perfusion limit or hammering limit then.

Existing vibrations tube-sinking cast-in-situ pile machine is made up of frame, hoist engine, immersed tube, vibrating hammer and suspension bucket five parts.Its mid frame plays a part to support hoist engine, the immersed tube that has flapper pile tip, vibrating hammer and suspension bucket; Hoist engine is the power-equipment of immersed tube and suspension bucket lifting; The immersed tube that has flapper pile tip is under the vibration hammer effect, can pass through cohesive soil, silt, mucky soil, mud, loose in soil layers such as close sand and artificial earth fill, with suspension bucket concrete is poured in the pipe then, extract immersed tube while shaking, form tube-sinking cast-in-situ pile by vibrating hammer.The cross section of existing immersed tube is circular, and the stake of its perfusion is the filled circles stanchion.Its weak point is, because the stake weekly form area of this castinplace pile unit volume is little, so side skin friction is little, cause the bearing capacity of this castinplace pile unit volume low, therefore, it is also just more to reach the used material of same bearer power, in the reinforcing of soft foundation, can increase substantially construction costs.

Summary of the invention:

The purpose of this utility model is, a kind of cross thin-walled pipe-sinking device that shakes the tube-sinking cast-in-situ pile machine is provided, and this pipe-sinking device is made up of body and flapper pile tip, and the cross section of body is a cross, is used to pour into the stake of cross thin wall concrete.Compare with existing filled circles stanchion, can improve bearing capacity 20%～30%, can reduce flabbiness ground strengthened construction costs significantly with the unit volume pile body of the cross thin wall concrete stake of the utility model perfusion.

For achieving the above object, the utility model adopts following technical measures:

Vibrations pipeline sinking pile machine is by frame, hoist engine, immersed tube, vibrating hammer and suspension bucket five parts are formed, its immersed tube is made up of body and flapper pile tip, its middle tube body is made of the cuboid right-angled intersection of two hollows, the centre of infall is interconnected, its cross section is the cross of hollow, the isosceles triangle that protrusion is all arranged in the perpendicular left and right sides in bottom and right-angled intersection place bottom of four lateral surfaces of body, its drift angle is 55～65 degree, flapper pile tip is made up of six rectangular slabs, two rectangular slab length are identical with the length that perforation body cross section cross erects, one side of two rectangular slabs is connected the perpendicular both sides of body bottom cross section cross with hinge respectively, in addition two sections length is identical about four rectangular slab length and body cross section cross horizontal stroke, one side of four rectangular slabs respectively with hinge be connected body bottom cross section cross horizontal stroke about two sections both sides, the width of six rectangular slabs is: when two relative rectangular slabs closed up, its drift angle was identical with the drift angle of the isosceles triangle that four lateral surfaces of body bottom protrude.

The utility model has the advantages that: the stake with the perfusion of cross thin-walled pipe-sinking device is the stake of cross thin wall concrete, compare with existing filled circles stanchion, unit volume pile body with the cross thin wall concrete stake of the utility model perfusion can improve bearing capacity 20%～30%, can reduce flabbiness ground strengthened construction costs significantly.
