Embodiment

[0024] combined with figure 1 , the present embodiment provides an expansion head construction device, including a vertical pipe 1 and a plurality of steel wire ropes 2, the bottom of the vertical pipe 1 is connected with a guide pipe 3 whose bottom end is in a horizontal state, and the steel wire rope 2 can be put into the guide pipe 3 At the same time, when the wire rope 2 in the guide tube 3 is driven by an external force, the bottom end of the wire rope 2 can be changed from a vertical state to a horizontal state and is led out horizontally from the bottom end of the guide tube 3; The vertical tube 1 and the guide tube 3 form an arc-shaped structure with a horizontal bottom end. When the steel wire rope 2 is thicker and harder, the vertical tube 1 and the guide tube 3 can be made to have a horizontal bottom end. Secondly, in order to facilitate the driving of the wire rope 2 in the vertical pipe 1 and the guide pipe 3 as a whole, in this embodiment, the top end of the wire...

Embodiment 2

[0032] In order to further expand the construction efficiency of the head, in this embodiment, the equipment provided in Embodiment 1 is further improved, and the improved technical features include:

[0033]A. Replace the grouting nozzle 6 with a grouting pipe 8 sleeved on the outer wall of the bottom end of the guide pipe 3 and distributed coaxially with the guide pipe 3. The two are fixedly connected, and at the same time, the grouting pipe 8 is provided with an external grouting pipe. In the annular grouting space 9 connected by the pipeline of the device 7, a plurality of grouting holes 10 which are distributed around the axis of the grouting pipe 8 and communicate with the grouting space 9 are evenly opened on the side wall of the grouting pipe 8 towards the outer side of the guide pipe 3, Thus, the defect of single grouting nozzle 6 is avoided, and multiple grouting holes 10 surround the guide tube 3 and the wire rope 2 to uniformly cut the soil in front of the wire rope...

Abstract

The invention discloses an expansion head construction device, which relates to a construction equipment, comprising a vertical pipe and a plurality of steel wire ropes. Under certain conditions, the bottom end of the wire rope set in the guide tube can be changed from a vertically downward state to a horizontal state and is led out of the guide tube, and the bottom end and the top end of the wire rope are also arranged above the vertical tube. A drive rod that is movably connected, the top of the drive rod is connected to a drive device that can drive it to rotate and descend, the length of the vertical pipe is not less than the length of the wire rope; the outer diameter of the wire rope is not less than 3cm; the A grouting nozzle connected to the external grouting device is also installed on the outer wall of the bottom end of the guide pipe; in this embodiment, the pile bottom beam can be effectively shaped, and the combination of multiple beams forms an anti-pulling expansion head structure, which can be compared with the traditional expansion head size. Significant growth, better anti-pulling effect.

Description

technical field [0001] The invention relates to a construction equipment, in particular to a construction pile bottom expansion head equipment. Background technique [0002] The traditional pile bottom expansion head is mostly used for anti-uplift, and the diameter of the pile bottom is mainly carried out by retractable equipment, etc., to form an enlarged head structure with the outer diameter of the bottom end larger than the outer diameter of the upper pile, thereby forming the anti-uplift effect. [0003] However, on the one hand, the traditional expansion head construction equipment is large in size, which is not conducive to the construction of small-diameter piles. It is difficult to manufacture; secondly, the formed enlarged heads are all cylindrical, and the size of the formed enlarged heads is only slightly larger than the size of the pile body, and the anti-pulling effect is poor. [0004] Therefore, it is urgent to provide an expansion head construction device w...
