Embodiment 1

[0051] The embodiment of the present application discloses a pilot hole pile planting equipment for preparing cement composite pipe piles. refer to figure 1 , The hole-leading pile-planting equipment is composed of a hole-leading mechanism 1 and a pile-planting mechanism 2.

[0052] refer to figure 1 , The hole guide mechanism 1 includes a drill bit 11, a drill pipe 12, a drilling power head 13, a mast 14, a traction rope 15, a hoist 16, a material delivery pipe 17, a follower frame 10, a positioning workstation 19 and a mobile chassis 18. Wherein, the mast 14 is fixed vertically on the upper surface of the mobile chassis 18; the winch 16 is fixed on the side of the mast 14, and the top of the mast 14 is also provided with a pulley block 141. One end of the traction rope 15 is connected to the winch 16, and the other end is fixedly connected to the follower frame 10 connected to the other side of the mast 14 by going around the pulley block 141; . The drill rod 12 is a ste...

Embodiment 2

[0068] The embodiment of the application discloses a pilot hole pile planting device and a construction method using the device. refer to Figure 5 , this embodiment is basically the same as Embodiment 1, except that the main blade 111 is a paddle-type blade, and its windward blade surface has an included angle of 135° with the rotation plane (ie, the horizontal plane). There are four main blades 111, which are evenly connected to the outer peripheral surface of the drill bit 11 through connecting columns.

[0069] refer to Figure 5 , the branch blade 112 is a rectangular piece, fixed vertically on the windward blade surface of the main blade 111 , and the length extension direction of the branch blade 112 is parallel to the length extension direction of the main blade 111 .

[0070]Through the above arrangement, under the mutual cooperation of the main blade 111 and the branch blade 112, the degree of agitation of the cement slurry can be improved, which can not only effec...

Abstract

The invention relates to the field of building construction, in particular to hole guiding and pile planting equipment and a construction method. The hole guiding and pile planting equipment comprises a hole guiding mechanism used for forming a drill hole in a construction site and a pile planting mechanism used for pressing a preset pipe pile into the drill hole. The hole guiding mechanism comprises a drill bit; a main blade is connected with the peripheral face of the drill bit; a plurality of branch blades are connected with the blade face of the main blade; and an included angle between each branch blade and the main blade ranges from 30 degrees to 90 degrees. The construction method adopting the hole guiding and pile planting equipment includes the steps of construction preparation, drilling and hole forming, cement pile manufacturing, core pile inserting and the like. According to the hole guiding and pile planting equipment and the construction method, through the mutual cooperation of the main blades and the branch blades, the stirring degree of cement paste is improved, so that the composition of the cement paste and mixing between the cement paste and soil particles in the drill hole are more sufficient, the cement paste is more uniform, the problem that the cement paste is locally solidified too early is solved, and a finally formed cement composite pile has better quality.

Description

technical field [0001] The present application relates to the field of building construction, in particular to a hole-leading pile planting equipment and a construction method. Background technique [0002] Engineering pile is a component that acts as a force, and is mainly used in pile foundation engineering. Pipe pile is a kind of engineering pile, and it is more and more widely used in the field of construction. Pipe piles can transfer the load of the superstructure to the deep soil layer with strong bearing capacity, or compact the soft soil layer to improve the bearing capacity of the foundation, thereby improving the stability of the superstructure. Building safety has a major impact. In current construction, pile sinking equipment is often used to press pipe piles into the ground. However, in complex strata such as deep sand layers, sandy pebble layers, and throwing fill layers, directly using pile sinking equipment to press pipe piles into the soil often has probl...
