[0002] Although the artificial dug pile, as a traditional pile-forming method, has relatively high construction risks, with the progress of technology and the application of various construction equipment, it has gradually been replaced by other construction methods. However, due to factors such as limited construction space and complex surrounding construction environment, it is necessary to use artificial dug piles for construction. At the same time, artificial dug piles also have advantages such as strong single-pile bearing capacity, good adaptability, and strong seismic resistance. Currently, the main retaining methods during the hole-forming process of artificial dug piles include cast-in-situ concrete retaining walls, precast concrete retaining walls, and steel section retaining walls. Among them, the cast-in-situ concrete retaining wall is still the most commonly used retaining wall method for artificial dug piles.

[0026] Please refer to Figures 1-6 , the present invention provides a construction method for the artificial dug pile wall protection of a quick-setting concrete auxiliary steel reinforcement cage, including the following steps: S1.

Trim the hole wall, fit the annular side plate 703 to the hole wall, and insert a number of longitudinal secondary rib load-bearing steel bars 700 on the inner bottom surface of the hole to match the hole shape, and spot-weld the longitudinal secondary rib load-bearing steel bars 700 to the side plate 703 to achieve fixation; S3. Spot-weld three circumferential main rib load-bearing steel bars 701 to a number of longitudinal secondary rib load-bearing steel bars 700 respectively to connect the circumferential main rib load-bearing steel bars 701 with a number of longitudinal secondary rib load-bearing steel bars 700; S4.

Wait for 2 hours for it to cure; S6. Repeat steps S1-S5.

[0027] As a further solution of the present invention, the material in S5 is a mixture of sulfoaluminate, lithium carbonate raw material, and concrete.

[0028] As a further solution of the present invention, the concrete spraying machine 100 includes a spraying pipe 101, the spraying pipe 101 is connected to the output end of the concrete spraying machine 100, an outer sleeve 203 is fixed on one side of the outer side wall of the spraying pipe 101, an outer shell 102 is arranged on one side of the outer side wall of the spraying pipe 101, the outer shell 102 is located outside the outer sleeve 203, a plurality of first piston holes 200 distributed in a circular pattern are formed on one side surface of the inner side wall of the outer shell 102, a plurality of second piston holes 202 distributed in a circular pattern are formed on the other side surface of the inner side wall of the outer shell 102, a communication hole 201 is formed on one side surface of the inner side wall of the first piston hole 200, and the communication hole 201 communicates with the second piston hole 202.

[0029] Through the provided first piston holes 200, second piston holes 202 and communication holes 201, communication can be formed between the first piston holes 200 and the second piston holes 202, thereby facilitating the compression of the water-ethylene glycol hydraulic oil in the communication holes 201.

[0030] As a further solution of the present invention, a plurality of first connecting rods 204 distributed in a circular pattern are fixed on one side surface of the outer sleeve 203, one end of the first connecting rod 204 is fixed with a first piston 205, the first piston 205 is movably engaged in the first piston hole 200, and a second piston 300 is movably engaged in the second piston hole 202.

[0031] Through the provided first piston 205 and second piston 300, the water-ethylene glycol hydraulic oil in the communication hole 201 can be pushed.

[0032] This solution has the following working process: During construction, first, manually dig a hole in the foundation with a depth of 1 meter; trim the hole wall, fit the annular side plate 703 to the hole wall, and insert a number of longitudinal secondary rib stress bars 700 on the inner bottom surface of the hole to match the hole shape, and spot-weld the longitudinal secondary rib stress bars 700 to the side plate 703 for fixation; spot-weld three circumferential main rib stress bars 701 to a number of longitudinal secondary rib stress bars 700 respectively to connect the circumferential main rib stress bars 701 with a number of longitudinal secondary rib stress bars 700; use a concrete spraying machine 100 to spray materials between the circumferential main rib stress bars 701 and the longitudinal secondary rib stress bars 700 to form a retaining wall; wait for 2 hours for it to solidify; repeat the above steps.

[0033] When spraying the material after mixing sulphoaluminate, lithium carbonate and concrete, first pour the mixed material into the concrete spraying machine 100. Then the operator holds the handle 103 and starts the concrete spraying machine 100. The concrete spraying machine 100 sprays the material between the circumferential main rib stress-bearing steel bars 701 and the longitudinal secondary rib stress-bearing steel bars 700 to form an anchor-sprayed retaining wall 702. When spraying, when the spraying pipe 101 generates a recoil force, the spraying pipe 101 moves backward, pushing the first connecting rod 204 to move. The movement of the first connecting rod 204 pushes the first piston to move. The movement of the first piston pushes the water-ethylene glycol hydraulic oil in the communication hole 201 to move, thereby causing the second piston to be pushed. The movement of the second piston pushes the second connecting rod 301 to move. The movement of the second connecting rod 301 pulls the connecting rope 304 to move, causing the stabilizing plate 306 to be pulled, and then pulling the spraying pipe 101 to form a force opposite to the recoil force of the spraying pipe 101. The two forces cancel each other out, enabling the recoil force of the spraying pipe 101 to be reduced. At the same time, when the spraying pipe 101 moves backward, several first magnets 401 and second magnets 501 on the side close to the concrete spraying machine 100 approach each other, increasing the repulsive force between the first magnets 401 and the second magnets 501 to form a reverse thrust, pushing the spraying pipe 101 away from the concrete spraying machine 100. Under the action of the repulsive forces between several first magnets 401 and second magnets 501 on both sides, the recoil force of the spraying pipe 101 is further reduced, causing the spraying pipe 101 to vibrate slightly.

[0034] According to the above working process, it can be seen that using the circumferential main rib stress-bearing steel bars 701 as the main stress-bearing steel bars can achieve effective protection during the process of manual hole digging. With the assistance of sulphoaluminate + lithium carbonate spraying for stress, the equal-strength time is 2 hours, greatly improving the construction efficiency.

[0035] Adopting the construction technology of spraying concrete for retaining wall construction reduces the construction difficulty of the retaining wall.

[0036] The construction inside the hole is simple in construction technology, avoiding the process of hoisting precast components and avoiding the risks of working in confined spaces.

[0037] Compared with precast retaining walls, the transportation process is avoided. The retaining wall can be used as a part of the pile body, reducing material waste and construction costs.

[0038] By setting the first piston 205, the second piston 300, the connecting rope 304 and the roller 305, when the spraying pipe 101 generates a recoil force, the second piston 300 can push the connecting rope 304 to move, thereby forming a force in the opposite direction to the recoil force of the spraying pipe 101, so that the recoil force of the spraying pipe 101 can be effectively reduced, avoiding the situation where the operator holds the spraying pipe 101 unstably and falls due to the large recoil force of the spraying pipe 101.

[0039] By setting the first magnet 401 and the second magnet 501 with the same polarity, when the spray pipe 101 moves backward, the repulsive force between the first magnet 401 and the second magnet 501 on the side close to the concrete spraying machine 100 is enhanced, and then the spray pipe 101 is pushed backward, so that the recoil force of the spray pipe 101 can be further reduced, and the spray pipe 101 can only vibrate slightly, further avoiding the situation that the operator holds the spray pipe 101 unstably and falls due to the large recoil force of the spray pipe 101.

[0040] As a further solution of the present invention, a plurality of side holes 303 distributed in a circumferential manner are formed on the other side surface of the inner side wall of the housing 102. An inner groove 302 is formed between the side surfaces of one side of the inner side walls of two adjacent side holes 303. A roller 305 is movably connected between the side surfaces of the inner side wall of the inner groove 302 close to each other. One end of the second piston 300 is fixed with a second connecting rod 301. The second connecting rod 301 passes through the second piston hole 202. One end of the second connecting rod 301 is fixed with a connecting rope 304. The connecting rope 304 passes through the roller 305 and the side hole 303.

[0041] By setting the connecting rope 304, when the spray pipe 101 moves backward, the first piston 205 can be pushed, and then the water-ethylene glycol hydraulic oil in the communication hole 201 can be pushed, so that the second piston 300 is pushed, and then the connecting rope 304 is pulled. The connecting rope 304 can pull the outer sleeve 203, so that the recoil force of the spray pipe 101 can be reduced.

[0042] As a further solution of the present invention, a stabilizing plate 306 is fixed on the other side surface of the outer sleeve 203. One ends of a plurality of connecting ropes 304 are fixed to one side surface of the stabilizing plate 306.

[0043] By setting the stabilizing plate 306, one end of the connecting rope 304 can be connected to the outer sleeve 203.

[0044] As a further solution of the present invention, two first mounting rings 400 are fixed on the inner side wall of the housing 102. A plurality of first magnets 401 distributed in a circumferential manner are respectively fixed on the side surfaces of the two first mounting rings 400 close to each other. A plurality of first partition plates 402 distributed in a circumferential manner are respectively fixed on the side surfaces of the two first mounting rings 400 close to each other. The plurality of first partition plates 402 are distributed in a staggered manner with the plurality of first magnets 401.

[0045] By setting the first partition plates 402, the magnetic forces between two adjacent first magnets 401 will not affect each other.

[0046] As a further solution of the present invention, two second mounting rings 500 are fixed on the outer side wall of the outer sleeve 203. On the side surfaces of the two second mounting rings 500 away from each other, a plurality of second magnets 501 distributed in a circular pattern are respectively fixed. On the side surfaces of the two second mounting rings 500 away from each other, a plurality of second partition plates 502 distributed in a circular pattern are respectively fixed. The plurality of second partition plates 502 and the plurality of second magnets 501 are distributed in a staggered manner, and are arranged in the same polarity relative to the first magnet 401 and the second magnet 501.

[0047] Through the provided second partition plates 502, the magnetic forces between adjacent two second magnets 501 will not affect each other. Through the arrangement that the first magnet 401 and the second magnet 501 are arranged in the same polarity, when the injection pipe 101 moves backward, it can be pushed in the opposite direction by the first magnet 401 and the second magnet 501, further reducing the recoil force.

[0048] As a further solution of the present invention, a plurality of engaging grooves 600 distributed in a circular pattern are formed on one side of the outer side wall of the injection pipe 101. On both sides of the inner side wall of the outer shell 102, a plurality of engaging blocks 601 distributed in a circular pattern are respectively fixed. The engaging blocks 601 are movably engaged with the corresponding engaging grooves 600. On both sides of the outer side wall of the outer shell 102, handles 103 are respectively fixed.

[0049] Through the provided engaging grooves 600 and engaging blocks 601, the position of the outer shell 102 can be movably limited, avoiding the situation that the outer shell 102 rotates.

[0050] In summary: During construction, first, manually dig a hole in the foundation with a depth of 1 meter; trim the hole wall, fit the annular side plate 703 to the hole wall, and insert a plurality of longitudinal secondary rib stress bars 700 on the inner bottom surface of the hole to match the shape of the hole. Spot-weld the longitudinal secondary rib stress bars 700 to the side plate 703 to achieve fixation; spot-weld three circumferential main rib stress bars 701 to the plurality of longitudinal secondary rib stress bars 700 respectively to connect the circumferential main rib stress bars 701 and the plurality of longitudinal secondary rib stress bars 700; use a concrete spraying machine 100 to spray materials between the circumferential main rib stress bars 701 and the longitudinal secondary rib stress bars 700 to form a retaining wall; wait for 2 hours for it to cure; repeat the above steps.

[0051] When spraying the material after mixing sulphoaluminate, lithium carbonate and concrete, first pour the mixed material into the concrete spraying machine 100. Then the operator holds the handle 103 and starts the concrete spraying machine 100. The concrete spraying machine 100 sprays the material between the circumferential main rib stress bar 701 and the longitudinal secondary rib stress bar 700 to form an anchor shotcrete retaining wall 702. When spraying, when the spray pipe 101 generates a recoil force, the spray pipe 101 moves backward, pushing the first connecting rod 204 to move. The movement of the first connecting rod 204 pushes the first piston to move. The movement of the first piston pushes the water-ethylene glycol hydraulic oil in the communication hole 201 to move, thereby causing the second piston to be pushed. The movement of the second piston pushes the second connecting rod 301 to move. The movement of the second connecting rod 301 pulls the connecting rope 304 to move, causing the stabilizing plate 306 to be pulled, and further pulling the spray pipe 101 to form a force opposite to the recoil force of the spray pipe 101. The two forces cancel each other out, so that the recoil force of the spray pipe 101 can be reduced. At the same time, when the spray pipe 101 moves backward, several first magnets 401 and second magnets 501 on the side close to the concrete spraying machine 100 approach each other, increasing the repulsive force between the first magnet 401 and the second magnet 501 to form a reverse thrust, pushing the spray pipe 101 away from the concrete spraying machine 100. Under the action of the repulsive force between several first magnets 401 and second magnets 501 on both sides, the recoil force of the spray pipe 101 is further reduced, causing the spray pipe 101 to vibrate slightly.

[0052] Among them, the first partition plate 402 and the second partition plate 502 are made of permalloy.

[0053] The concrete spraying machine 100 can be purchased on the market, which is a mature technology in this field and has been fully disclosed, so it will not be repeated in the specification.

[0054] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.

The plurality of second partition plates 502 and the plurality of second magnets 501 are staggered and are arranged in the same polarity relative to the first magnet 401 and the second magnet 501.

9. A quick-setting concrete auxiliary steel cage artificial bored pile wall protection construction method according to claim 8, characterized in that: A plurality of circumferentially distributed snap-fitting grooves 600 are provided on one side of the outer wall of the spray pipe 101, and a plurality of circumferentially distributed snap-fitting blocks 601 are fixed on both sides of the inner wall of the shell 102. The snap-fitting blocks 601 are movably engaged with the snap-fitting grooves 600, and handles 103 are fixed on both sides of the outer wall of the shell 102.

10. The method for wall protection of quick-setting concrete auxiliary steel cage bored piles according to claim 1, characterized in that: The steps of spraying by the concrete spraying machine 100 include the following steps: S1. First, the mixed material is poured into the concrete spraying machine 100. Then, the operator holds the handle 103 and starts the concrete spraying machine 100. The concrete spraying machine 100 sprays the material into the space between the annular main rib stress reinforcement 701 and the longitudinal secondary rib stress reinforcement 700 to form an anchor spraying protective wall 702. S2. When spraying, when the spray pipe 101 produces recoil, the spray pipe 101 moves backward, pushing the first connecting rod 204 to move, the first connecting rod 204 moves to push the first piston to move, the first piston moves to push the water-glycol hydraulic oil in the connecting hole 201, and then the second piston is pushed, the second piston moves to push the second connecting rod 301 to move, the second connecting rod 301 moves to pull the connecting rope 304 to move, so that the stabilizing plate 306 is pulled, and then the spray pipe 101 is pulled to form a force opposite to the recoil of the spray pipe 101, the two forces offset each other, so that the recoil of the spray pipe 101 can be reduced; S3. When the injection pipe 101 moves backward, the first magnets 401 and the second magnets 501 on one side of the concrete spraying machine 100 are brought closer to each other, so that the mutual repulsion between the first magnets 401 and the second magnets 501 increases, forming a reverse thrust, pushing the injection pipe 101 away from the concrete spraying machine 100. Under the action of the mutual repulsion between the first magnets 401 and the second magnets 501 on both sides of the injection pipe 101, the recoil force is further reduced, causing the injection pipe 101 to vibrate slightly.
