Abstract

The utility model relates to a flushing gas lift pile sinking construction device which has the technical scheme that the utility model is composed of a crane and a static pile press provided with a pipe pile clamp. The utility model has the improvement that a lift hook on the crane is lifted with a gas flushing pipe and a water flushing pipe, wherein one end of the gas flushing pipe and one end of the water flushing pipe are respectively connected with an air compressor and a centrifugal pump; the other end of the gas flushing pipe and the other end of the water flushing pipe are arranged in a through hole of a prefabricating pipe pile. In addition, the air compressor is connected with a gas storage tank and the centrifugal pump is connected with a water reservoir. The utility model has the advantages that an original static pressure method construction device is improved to be suitable for the flushing gas lift method auxiliary pile sinking technology adopted in the construction at present, the adaptability of the static pressure method construction for geology is improved and the work efficiency is improved.

Description

Piling construction equipment is lifted in the water qi of chong channel ascending adversely

Technical field

The utility model relates to Foundation Design, especially belongs to the construction equipment of pile tube pile sinking in the foundation construction process.

Background technology

In current industrial, in the civilian construction, prestressed high-strength concrete pile is widely adopted, it has the bearing capacity height, anti-bending strength is good, good endurance, the construction early-stage preparations time is short, many advantages such as speed of application is fast, obtained using widely in the most of area of China in recent years, at riverine extra large soft clay area dominate more, the prestressed high-strength concrete pile main construction method is a static pressure method at present, there is obvious weakness in the static pressure construction prestressed high-strength concrete pile aspect the geology applicability, be exactly that it is thicker in sand content, pile sinking poor performance in the higher sandy soil layer of density, and design requires to penetrate this layer, to guarantee the requirement of bearing capacity.For solving the static pressure construction prestressed high-strength concrete pile in the obvious weakness that exists aspect the geology applicability.The improvement that the utility model carries out former static pressure construction equipment is so that be applicable to that the water that adopts in the present construction is towards gas lift method auxiliary pile sinking technology.

Summary of the invention

The purpose of this utility model is to make it the improvement undertaken by to former static pressure construction equipment to be applicable to the water that adopts in the present construction towards gas lift method auxiliary pile sinking technology, and improved the compliance of static pressure construction to geology greatly, has improved operating efficiency.

Technical solution adopted in the utility model is: it is made up of crane and the static pile press that has the pile tube anchor clamps, its improvements are, suspension hook on the crane is lifted with qi of chong channel ascending adversely pipe and the jet water spout that an end is connected with centrifugal pump with air compressor respectively, the other end of qi of chong channel ascending adversely pipe and jet water spout is contained in the through hole of prefabricated tubular pile, in addition, air compressor links to each other with gasholder, and centrifugal pump links to each other with reservoir.

Description of drawings

Fig. 1 is the utility model schematic diagram

Wherein: 1, crane 2, static pile press 3, prefabricated tubular pile 4, jet water spout 5, qi of chong channel ascending adversely pipe 6, centrifugal pump 7, reservoir 8, air compressor 9 gasholder 10, special-purpose tip 11, suspension hook 12, pile tube anchor clamps 13, through hole

The specific embodiment

Further set forth specific embodiments of the present utility model below in conjunction with accompanying drawing, as shown in Figure 1, the utility model is made up of crane 1 and the static pile press 2 that has pile tube anchor clamps 12, wherein pile tube anchor clamps 12 are used to clamp prefabricated tubular pile 3, in the utility model, suspension hook 11 on the crane 1 is lifted with qi of chong channel ascending adversely pipe 5 and jet water spout 4, one end of qi of chong channel ascending adversely pipe 5 and jet water spout 4 is connected with centrifugal pump 6 with air compressor 8 respectively, and the other end of qi of chong channel ascending adversely pipe 5 and jet water spout 4 is contained in the through hole 13 of prefabricated tubular pile 3, in addition, air compressor 8 links to each other with gasholder 9, and centrifugal pump 6 links to each other with reservoir 7.Crane 1 adopts tracklaying crane, truck mounted crane, wheeled crane in the utility model.

Operating principle of the present utility model is, pile tube anchor clamps 12 of prefabricated tubular pile 3 being sling and being put into static pile press 2 with crane 1 at first, and be pressed into underground gradually, sling qi of chong channel ascending adversely pipe 5 and jet water spout 4 of suspension hook 11 then, and an end of qi of chong channel ascending adversely pipe 5 and jet water spout 4 packed in the through hole 13 of prefabricated tubular pile 3, when static pile press 2 is pressed into prefabricated tubular pile 3 when underground gradually, air compressor 8 and centrifugal pump 6 will have the gas of pressure and water by qi of chong channel ascending adversely pipe 5 and jet water spout 4 through hole 13 along prefabricated tubular pile 3, pour the layer of sand of 10 ends of the special-purpose tip of underground direct impact via special-purpose tip 10, utilize backwater, the sand effect of taking of return-air, take away an end sub-sand, little gravel, thereby reduce the compactness of soil layer, reduce end resistance, to reach the purpose of pile sinking.

Of the present utility model implement to make on the one hand originally must design alteration be that the design of high cost stake type such as drill hole pouring pile need not to change, and saved investment, avoided construction delay.Also expanded the static pressure construction scope of application on the other hand, for Construction unit and designer have increased a not only selection of economy but also safety.
