Embodiment 1

[0046] like figure 2 As shown, a pile-forming device for manufacturing tube-plate joint piles includes a tube-pile pile-forming device 201. A vertical sheet pile forming device 202 is welded on the upper side of the outer tube cylinder. The sheet pile forming device 202 is a plate body with a U-shaped cross section. The free opening end of the sheet pile forming device 202 is welded on the barrel pile. On the upper side of the outer tube cylinder of the pile forming device 201, the central plane of the sheet pile forming device 202 and the axis of the cylindrical pile forming device 201 are in the same plane, and the height of the sheet pile forming device 202 is smaller than that of the cylindrical pile forming device 201 height, the top surface of the sheet pile forming device 202 is flush with the top surface of the cylindrical pile forming device 201, and the first pile tip 203 is installed at the bottom of the cylindrical pile forming device 201. The structure of the fir...

Embodiment 2

[0056] In use, the difference from Embodiment 1 is that the strip plate 205 at the bottom of the sheet pile forming device 202 is squeezed by the soil during the sinking process, and is in a closed state, and the soil is discharged to both sides, without It will enter the pile-forming space, and in the process of pulling up, it is in an open state due to the extrusion of concrete, so that piles can be formed smoothly.

[0057] Example 3:

Embodiment 3

[0059] The difference between the pile forming device in the present embodiment 3 and the embodiment 1 is: as Figure 11 As shown, the second pile point 204 is not a triangular prism, but includes two strip plates 205 and a triangular pyramid frustum that is placed horizontally on one side of the two strip plates 205 and has a point downward. The upper end faces of the strip plates 205 are respectively hinged with the two opposite end faces at the bottom of the sheet pile forming device 202, and the lower ends of the two strip plates 205 are overlapped together to form a V-shaped structure in the longitudinal section. The two strip plates 205 The same end face of the same side of the triangular pyramid body is seamlessly fitted with the smaller end face of the triangular pyramid body, and the other end faces of the two strip plates 205 are all connected to the end face of the sheet pile forming device 202 which is far away from the tube pile forming device 201. The sides are s...

Abstract

The invention relates to a cast-in-place concrete tube-sheet pile, a piling device and a piling construction method thereof, which aims to provide a tube-sheet pile, a piling device and a piling construction method thereof, wherein the tube-sheet pile is formed by connecting a tube pile and a sheet pile into a whole and can be integrally formed and be capable of accelerating a construction progress. The cast-in-place concrete tube-sheet pile comprises a vertical cylindrical tube pile, the sheet pile is arranged at one side or two sides of the tube pile and is in a vertical cuboid structure, the tube pile and the sheet pile are arranged in stagger, the center surface of the sheet pile and the axial line of the tube pile are on the same plane, the sheet pile is located at the upside of the outer cylindrical surface of the tube pile, and the depth of the sheet pile is less than that of the tube pile. The cast-in-place concrete tube-sheet pile has the advantages that because the tube pileand the sheet pile are utilized as a whole, the strength of the whole pile foundation is improved; because the depth of the sheet pile is less than that of the tube pile, the consumption of materialsis reduced, the cost is saved, and the cast-in-place concrete tube-sheet pile can be widely applied to foundation engineering, such as ocean, water conservancy, roads and bridges, airport traffic zones, industrial and civic buildings and the like.

Description

technical field [0001] The invention relates to a cast-in-place concrete tube-slab joint pile, a pile-forming device and a pile-forming method thereof, in particular to a tube-slab joint pile structure, a pile-forming device and a pile-forming method suitable for cast-in-situ concrete with large diameter and ribs construction method. Background technique [0002] With the continuous deepening of my country's reform and opening up, my country's economic construction has developed steadily and rapidly, especially the economic development of coastal areas has achieved world-renowned achievements. As we all know, land resources are an important basis for economic development. With the rapid development of the economy, construction land is becoming increasingly scarce. It has become a consensus in coastal economically developed areas to ask for land from tidal flats. In addition, the number of foundation pit enclosures and foundation treatments for housing construction However, ...
