Abstract
The utility model relates to a cast-in-place concrete thin-wall pipe pile driver used for construction. The utility model adopts a composite foundation mould sinking structure; the upper part of the structure is a monolayer steel pipe, which is connected with a vibration head at the upper part, and the lower part is a double-layer internal and external casing cavity structure, which is connected with the flapper pile shoe structure and molding and lubricating grout producer at the lower part. The monolayer steel pipe is far longer than the double-layer internal and external cavity structure, and the pumping-pressure concrete conveying pipe and the concrete feeding exploring tube are symmetrically arranged on the inner side of the monolayer steel pipe, and a detector is positioned in the exploring tube. The utility model solves the defects that lateral friction resistance is great, the finished piles are easy for segregation, the vibration head efficiency is low, and the pull-out capacity is insufficient and so on, can form an enlarged-head pile and has advantages of quick construction speed, small influence to ambient earth and great cost reduction.
Description
Technical field
The utility model relates to a kind of construction machinery, particularly a kind of cast-in-place concrete thin-walled pile tube machine.
Background technology
Before the utility model is made, existing a kind of sleeve pipe sinks mould pouring pipe pile with large diameter machine, adopt steel internal and external casing cavity structure, under the protection of flap valve pile shoe structure closure, hit the internal and external casing cavity structure by the vibration head vibration, sink to the ground projected depth, in the internal and external casing cavity structure, inject concrete by the concrete current divider then, finish after vibration and extract this structure; In the process that sinks to and extract, molding slurry-making device injects lubricated slurry to the cavity medial and lateral, and the flap valve pile shoe structure separates when extracting automatically, forms the concrete thin-wall pile tube at last.But it is big that this machine exists internal and external double-layer side direction frictional resistance when squeezing into or extract, require vibration head that bigger power is arranged, bigger equipment uplift resistance also will be arranged, and double-deck internal and external casing stake is oversize, reaches more than 10 meter usually, and concrete is as easy as rolling off a log generation segregation phenomenon in formation of pile, cause the pile quality problem, internal and external casing and soil contact face are long-pending big, vibrate greatly to the surrounding soil influence basin, can't form enlarged footing and significantly improve defective such as bearing capacity of single pile.
Summary of the invention
The purpose of this utility model just is to overcome above-mentioned defective, designs a kind of new cast-in-place concrete thin-walled pile tube machine.
The technical solution of the utility model is: comprise vibration head, its major technique is characterised in that and connects the heavy mode structure top of compound ground under the vibration head.
Its further technical scheme be compound ground to become the first half of mode structure be the monolayer steel pipe structure, on connect vibration head, the latter half is double-deck internal and external casing cavity structure.
Advantage of the present utility model is that with effect owing to compound ground becomes the mode structure first half be monolayer steel pipe, defectives such as the side direction frictional resistance is big, pile is easily emanated, vibration head efficient is low, uplift resistance deficiency have been solved, form the enlarged footing stake, by the pump pressure delivering concrete, speed of application is accelerated, when reducing piling construction to the influence of soil layer on every side; Simple in structure, cost reduces greatly.

The specific embodiment
As shown in the figure, Equipment Foundations 1 are fixedlyed connected with the bottom of gantry support 2, connect vibration head 3 under in gantry support 2 tops, the fixedly connected compound ground in vibration head 3 lower ends sinks mode structure 4, and the first half of the heavy mode structure 4 of compound ground is a monolayer steel pipe 5, on connect vibration head 3, the latter half is double-deck internal and external casing cavity structure 6, still form one, the first half length is made by steel material much larger than the latter half.The lubricated pulping device 10 of mould is arranged in medial and lateral, double-deck internal and external casing cavity structure 6 lower end, forms inner and outer ring, connects flap valve pile shoe structure 11 on the bottom outer tube of double-deck internal and external casing cavity structure 6; Pump pressure elephant trunk 7 and concrete charging sound-pipe 8 are symmetricly set on the monolayer steel pipe 5, and concrete charging probe 9 is set in sound-pipe 8.
During work, Vibration on Start-up 3 is downward, the heavy mode structure 4 of the compound ground that is attached thereto is driven in the ground, flap valve pile shoe structure 11 is between the inner and outer pipe of the lower end of double-deck internal and external casing cavity structure 6, it is closed most advanced and sophisticated to form the top, protect the heavy mode structure 4 of compound ground to sink to the predetermined design reinforcement degree of depth, form tubular die in the ground; Pump pressure elephant trunk 7 evenly injects concrete in the double-deck internal and external casing cavity structure 6 of lower end, inject of probe 9 detections, the control of the hoisting velocity of the heavy mode structure 4 of concrete amount and compound ground by concrete charging sound-pipe 8, probe 9 is actual to be a detection mark post, be carved with yardstick above, increase along with the concrete injection rate, upwards lift probe 9 gradually, by reading the size on it, just know and injected many a spot of concrete, and also need to inject many a spot of concrete; When the heavy mode structure 4 of compound ground promoted, the top of flap valve pile shoe structure 11 separated automatically, thereby has just formed concrete tubular pile between the soil body in ring domain.In pile and pile pulling process, molding slurry-making device 10 is gone into lubricated slurry to the inner and outer pipe wall pressure of double-deck internal and external casing cavity structure 6, reduces the resistance of double-deck internal and external casing cavity structure 6 side soil when squeezing into and extract; When fluid concrete first, strengthen pumping pressure, and reduce the hoisting velocity of the heavy mode structure 4 of compound ground, then can form the enlarged footing stake.
