[0002] In the laying of communication engineering lines, excavation and piling are two key construction processes, which are usually used to provide a reliable foundation for line facilities, pipelines or supporting structures to ensure the safety and stability of communication lines. Before laying pipelines, cables and optical cables, trenches and holes need to be opened in the construction area to provide installation space for the lines and pipelines to ensure that the lines and pipelines can be laid at an appropriate depth to avoid interference and damage from external factors.

[0003] When laying communication lines on soft soil, slopes, river banks or other unstable terrain, risks such as settlement and landslides may occur more easily. The usual solution is to carry out multi-point piling in the construction area, which can greatly improve the stability and seismic resistance of the soil structure.

[0021] Compared with the prior art, the advantages of the present invention are:

[0022] 1. Based on the traditional method of digging tunnels by rotating the drill bit driven by a motor, the present invention pumps high-pressure air generated by a gas compressor into the cylinder. The high-pressure air can gush out from the bottom of the cylinder to push away the soil and rocks in the tunnel, accelerate the separation of impurities, effectively avoid drill bit blockage, and improve drilling efficiency. It can also drive the inner sliding column to slide downward regularly through the rotating mechanism, drive the transmission mechanism to slide synchronously, and make the transmission column generate a downward thrust. The thrust is applied to the transmission column, which can not only drive the originally rotating drilling mechanism to push downward, increase the impact on the soil or rock layer, and improve the drilling efficiency, but also after the drilling mechanism is replaced with a foundation pile, it can also impact the foundation pile, so that the foundation pile can be quickly installed in the tunnel, greatly accelerating the installation efficiency of the foundation pile. When the ejection mechanism is driven to slide downward regularly by high-pressure air, it also has the function of connecting the airway with the air inlet chamber, and at the same time moving the top platform, opening the air distribution port, and introducing the high-pressure air between the cylinder and the partition into the air inlet chamber, and then finally into the drill bit through the airway, pushing the disc to slide downward, so that the impact rod extends from the bottom of the drill bit, further exerting impact force on the soil or rock layer, better crushing the rock layer and other hard bottom layers, accelerating the excavation speed, and improving the drilling efficiency.

[0023] 2. A slag cleaning mechanism is installed on the outside of the cylinder. When the cylinder sinks to dig holes, the ring seat is stably installed on the top of the hole by means of pins, which protects the top edge of the hole and prevents collapse. Moreover, when the cylinder sinks, the spiral groove on its surface moves downward. The spiral groove cooperates with the convex rod on the inner wall of the swivel to drive the swivel to rotate, thereby driving the shift plate to rotate. The arc-shaped shift plate rotates clockwise to shift the soil or rocks accumulated around the hole away from the hole, which can avoid soil accumulation and not affect the construction of workers, and prevent soil from flowing back and blocking the hole.

[0050] An ejection mechanism 5 is installed inside the partition cylinder 41, and the ejection mechanism 5 includes a sliding column 51 slidably connected to the inside of the rotating cylinder 46, and a zigzag groove 52 is provided on the surface of the sliding column 51, and a plurality of protrusions 48 are slidably connected in the zigzag groove 52. An inner sliding column 53 is installed at the bottom of the sliding column 51, and a plurality of air intake cavities 54 are penetrated through the cylindrical surface of the inner sliding column 53, and the air intake cavity 54 penetrates the bottom surface of the inner sliding column 53, and two pressure blocks 55 are symmetrically installed on the bottom surface of the inner sliding column 53.

[0051] The transmission mechanism 6 also includes a top platform 61 slidably connected to the inside of the partition 41, the top platform 61 is installed on the top surface of the transmission column 63, a second spring 62 is installed on the top platform 61, an air duct 64 is provided in the top platform 61 and the transmission column 63, a third spring 65 and a wedge block 66 are symmetrically installed inside the top surface of the top platform 61, the wedge block 66 is elastically connected to the top surface of the top platform 61 through the third spring 65, a closing valve 67 is fixed on the side of the wedge block 66, the closing valve 67 is slidably connected to the top of the air duct 64, a slot 693 is provided at the bottom of the transmission column 63, and the air duct 64 is connected to the slot 693.

[0052] The drilling mechanism 7 also includes a column 71 installed inside the slot 693. The column 71 is arranged on the top surface of the drill bit 72, and the mounting ring 692 is installed on the top of the column 71. A channel 73 is provided in the column 71. A disc 74 and a fourth spring 76 are installed inside the drill bit 72. A plurality of impact rods 75 are distributed on the bottom surface of the disc 74, and the impact rods 75 penetrate the bottom surface of the drill bit 72. The disc 74 is elastically connected to the drill bit 72 through the fourth spring 76.

[0053] During the soil drilling process of the drilling mechanism 7, the gas compressor 12 on the vehicle body 11 works at the same time, and high-pressure air enters the shell 43 through the ventilation pipe 13. The high-pressure air passes through the annular inner cavity of the shell 43, driving the turbine 44 to rotate, and the high-pressure air is discharged upward from the air outlet on the top of the shell 43. The arc-shaped dome 33 on the top of the cylinder 31 is used to guide the high-pressure air downward. The cylinder 31 and the partition 41 are not fitted together, but there is a certain gap. The high-pressure air diffuses to the bottom of the cylinder 31 through the gap between the cylinder 31 and the partition 41, and is blown out from the bottom of the cylinder 31; at the same time, a plurality of air outlet holes 34 are provided on the bottom side of the cylinder 31, so that the high-pressure air is blown out from the side of the cylinder 31. The high-pressure air starts to fill the channel from the bottom of the cylinder 31 and fills the entire channel from bottom to top. The soil, rocks and other materials crushed by the drill bit 72 are pushed out of the channel under the pressure of the high-pressure air, thereby ensuring the smoothness of the drilling of the drilling mechanism 7.

[0054] When the high-pressure air drives the turbine 44 to rotate, the turbine 44 also drives the support shaft 42 and the rotating drum 46 to rotate (the turbine 44 and the rotating drum 46 are connected by a reducer 491), the support shaft 42 rotates at the top of the cylinder 31, and the rotating drum 46 drives a number of protrusions 48 on its inner wall to rotate, and the protrusions 48 slide in the zigzag grooves 52 on the surface of the sliding column 51. The cooperation between the protrusions 48 and the zigzag grooves 52 can make the sliding column 51 slide downward and reset upward in the rotating drum 46, and the action is cyclic. The sliding of the sliding column 51 will stretch and reset the first spring 47, and at the same time, the sliding column 51 drives the inner sliding column 53 to slide up and down in the partition 41. When the inner sliding column 53 slides downward, it pushes the top platform 61 at its bottom Sliding downward synchronously, the top platform 61 compresses the second spring 62 and drives the transmission column 63 to slide downward. The transmission column 63 drives the drilling mechanism 7 to move downward, so that the drill bit 72 forms a downward push-out trend, thereby increasing the impact on the soil or rock layer, cooperating with the rotation and excavation of the drill bit 72, and thus greatly improving the drilling efficiency.

[0055] When the inner sliding column 53 pushes the top platform 61 to slide downward, the air distribution port 49 in the middle of the partition tube 41 is exposed (when the top platform 61 is not moving, the air distribution port 49 is closed by the cylindrical surface of the top platform 61), and a part of the high-pressure air between the cylinder body 31 and the partition tube 41 enters the partition tube 41 through the air distribution port 49. While the inner sliding column 53 is sliding downward, not only the air intake cavity 54 provided on the cylindrical surface of the inner sliding column 53 gradually communicates with the air distribution port 49, guiding the high-pressure air to the bottom of the inner sliding column 53, but also the pressure block 55 at the bottom of the inner sliding column 53 will resist and push the wedge block 66 toward the outer edge of the top platform 61. The wedge block 66 compresses the third spring 65 and drives the air closing valve 67 in the air passage 64 to slide into the interior of the top platform 61, so that the air passage 64 is connected with the air intake cavity 54 at the bottom of the inner sliding column 53. The high-pressure air passes through the air passage 64 and penetrates the inner sliding column 53. The high-pressure air passes through the worm gear 691 and the mounting ring 692 (the worm gear 691 and the mounting ring 692 are hollow structures, and their inner diameter size is the same as the size of the airway 64) and the channel 73 in the plug column 71, and finally the disc 74 inside the drill bit 72 is squeezed, so that the disc 74 drives the impact rod 75 to move downward, compressing the fourth spring 76, and the impact rod 75 extends from the bottom of the drill bit 72, further exerting pressure on the soil layer or rock layer, better crushing the bottom layer with greater hardness such as the rock layer, accelerating the excavation speed, and improving the drilling efficiency.

[0056] When replacing the drilling mechanism 7, remove the screw 77, loosen the column 71 and the mounting ring 692 inserted into the slot 693, and pull the drilling mechanism 7 to separate the column 71 from the slot 693. Then insert the pile into the slot 693. As the reel 24 rotates, the cable 25 is released, and the cylinder 31 drives the pile to sink into the drilled channel. In order to improve the efficiency of installing the pile into the channel, the inner sliding column 53 can also be used to regularly impact the transmission mechanism 6, so that the transmission column 63 transfers kinetic energy to the pile. Under the action of the impact force, the pile can be quickly driven into the channel, effectively improving the installation rate of the pile.

[0057] Example 3: This example is an explanation based on Example 1. For details, please refer to Figures 1 to 11 A slag cleaning mechanism 8 is installed on the outer side of the bottom end of the cylinder 31, and the slag cleaning mechanism 8 includes a ring seat 81 sleeved on the outer side of the cylinder 31, a rotating groove 82 is provided on the top surface of the ring seat 81, a slope protection ring 83 is fixed to the inner wall of the bottom surface of the ring seat 81, and a plurality of pins 84 are arranged in a circular array on the bottom surface of the ring seat 81. A swivel 85 is rotatably connected to the top surface of the ring seat 81, a plurality of pulleys 86 are installed at the bottom of the swivel 85, and the pulley 86 is slidably connected in the rotating groove 82, a plurality of dial plates 87 are arranged in a circular array on the outer wall of the swivel 85, a convex rod 88 is fixed on the inner wall of the swivel 85, and the convex rod 88 is slidably connected in the spiral groove 32, a plurality of positioning wheels 89 are arranged in a circular array on the inner walls of the swivel 85 and the slope protection ring 83, and the positioning wheels 89 abut against the surface of the cylinder 31.

[0058] The outside of the cylinder 31 is also equipped with a slag cleaning mechanism 8. The swivel ring 85 and the positioning wheels 89 installed on the inner wall of the slope protection ring 83 always contact the inner wall of the cylinder 31, so that the ring seat 81 and the rotating groove 82 always remain concentric with the cylinder 31. When drilling, a large amount of soil and rocks will gush out from the hole. A large amount of soil and rocks will accumulate around the hole, which not only affects the construction of workers, but also easily buries the hole. Therefore, when the cylinder 31 sinks, it will drive the slag cleaning mechanism 8 to move downward, and finally make the pin 84 at the bottom of the ring seat 81 contact the ground, and the pin 84 is inserted into the soil, so that the ring seat 81 can be firmly installed on the ground at the top of the hole. At this time, the slope protection ring 83 at the bottom of the inner wall of the ring seat 81 is just inserted into the inside of the hole, fits the inner wall of the hole, protects the top of the hole, and avoids landslides. As the cylinder 31 continues to sink, the spiral groove 32 on the surface of the cylinder 31 will drive the protruding rod 88 on the inner wall of the swivel 85 to rotate inside it, thereby driving the swivel 85 to rotate, so that the plurality of pulleys 86 at the bottom of the swivel 85 slide in the rotating groove 82 at the top of the ring seat 81 to ensure smoothness, and the swivel 85 drives the paddle 87 to move in a circle. The paddle 87 is designed in an arc shape. When it rotates in its predetermined direction, it can push the soil and rocks around it away from the axis, so that the excavated soil and rocks are kept away from the channel, which can avoid soil accumulation and not affect the construction of workers, and prevent soil from flowing back and blocking the channel.

[0059] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the protection scope of the present invention.
