Description

Technical Field

[0001] The invention belongs to the technical field of construction pile forming, in particular to a forming method of high-strength prestressed low-carbon construction pile. Background Art

[0002] In construction engineering, construction piles are an important form of foundation structure and are widely used in foundation treatment under various complex geological conditions. However, the traditional construction pile forming method has some inherent problems, especially the lack of prestress and stability.

[0003] The traditional method of forming construction piles is usually through a simple drilling process, and then the steel structure construction piles are directly inserted into the hole. Although this method meets the needs of foundation treatment to a certain extent, there are obvious problems of insufficient prestress and stability. Due to the irregular hole wall and residual impurities in the hole that may be generated during the drilling process, as well as the uneven resistance that the steel structure construction piles may encounter when inserted into the hole, the construction piles may be subjected to uneven stress distribution during subsequent use, thereby affecting their prestressing effect.

[0004] Secondly, in the process of pouring self-compacting slurry through this method, it was found that it is often difficult to completely eliminate bubbles in the self-compacting slurry during the pouring process, resulting in defects inside the pile body, reducing its density and uniformity, thereby affecting the overall quality of the pile body. For this reason, a forming method for high-strength prestressed low-carbon piles is proposed. Summary of the invention

DETAILED DESCRIPTION

[0039] The technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0040] Embodiment 1:

[0041] The present application provides a method for forming high-strength prestressed low-carbon construction piles, the specific steps of which include:

[0042] S1. Processing the construction waste soil and other required raw materials through a specific processing technology to convert them into a self-compacting slurry state with good fluidity. Subsequently, using a drilling device, according to specific engineering requirements, holes with different diameters are drilled on the ground, wherein the composition and processing technology of the self-compacting slurry are implemented in accordance with the contents disclosed in the invention patent publication number CN112707685A;

[0043] S2. Pour the prepared fluid self-compacting slurry into the drilled hole through a pouring device to ensure that the self-compacting slurry can fully fill the entire hole;

[0044] S3. Insert the low-carbon I-shaped steel into the drilled hole after pouring the self-compacting slurry. After the fluid self-compacting slurry solidifies and hardens, it forms an integrated pile body with the low-carbon I-shaped steel.

[0045] Embodiment 2:

[0046] Based on Example 1, please refer to Figure 1-Figure 9 The grouting equipment includes a grouting cylinder 1, a partitioning circular plate 2 is fixedly connected to the inside of the grouting cylinder 1, a driving mechanism 3 is arranged on the partitioning circular plate 2, a hole cleaning mechanism 5 is installed on the driving mechanism 3, the hole cleaning mechanism 5 includes a second connecting disc 51 and a fixing seat 56 arranged above the second connecting disc 51, the second connecting disc 51 is provided with driving angle irons 52 arranged in a circular array, the fixing seat 56 is fixedly installed with guide tubes 53 arranged in a circular array, and a hole cleaning rod 54 is slidably installed inside the guide tube 53, A reset spring 55 is provided between the fixed seat 56 and the hole cleaning rod 54 for resetting the hole cleaning rod 54. A connecting shaft 57 is fixedly installed on the lower end of each hole cleaning rod 54. A transmission angle iron 58 used in conjunction with the driving angle iron 52 is fixedly installed on the lower ends of the multiple connecting shafts 57. The directions of the inclined surfaces of the driving angle iron 52 and the transmission angle iron 58 are opposite. A No. 2 slide groove 531 is opened on each of the guide tubes 53, and the multiple connecting shafts 57 slide in the No. 2 slide groove 531 respectively.

[0047] Specifically, the second connecting disc 51 is driven to rotate by the driving mechanism 3, and the rotation of the second connecting disc 51 drives the multiple driving angle irons 52 thereon to rotate. The inclined surface of the driving angle iron 52 can squeeze the inclined surface of the transmission angle iron 58 closest to it, thereby pushing the transmission angle iron 58 to move, and the transmission angle iron 58 drives the connecting shaft 57 to move. Because the connecting shaft 57 is inside the second slide groove 531, the second slide groove 531 plays a role of linear guidance, thereby pushing the hole cleaning rod 54 to slide outside the guide tube 53, and the hole cleaning rod 54 moves. The grouting tube 1 is re-inserted into the slurry outlet 12 arranged on the grouting tube 1. Therefore, it is prevented that during the process of pushing the grouting tube 1 deeper into the hole, stone debris or soil in the hole accidentally falls into one or more of the slurry outlets 12, blocking the slurry outlets 12, resulting in the fluid slurry being unable to flow out from the inside of these slurry outlets 12, thereby resulting in a smaller flow rate of the fluid slurry, which affects the injection rate, not only wasting time, but also long-term injection is likely to cause the self-compacting slurry to solidify, which is not conducive to the later insertion of low-carbon I-shaped steel.

[0048] In this embodiment, the driving mechanism 3 includes a No. 1 driving motor 31 fixedly mounted on the bottom surface of the partition circular plate 2, a No. 1 driving gear 32 fixedly mounted on the output end of the No. 1 driving motor 31, the No. 1 driving gear 32 is meshingly connected with a driven gear 33, a transmission shaft 34 is fixedly mounted on the driven gear 33 and rotatably mounted, and the transmission shaft 34 is rotatably mounted on the partition circular plate 2, and the No. 2 connecting disc 51 is fixedly mounted on the upper end of the transmission shaft 34.

[0049] Specifically, by starting the No. 1 driving motor 31 to drive the No. 1 driving gear 32 to rotate, the No. 1 driving gear 32 drives the driven gear 33 to rotate, and the driven gear 33 drives the transmission shaft 34 to rotate. The rotation of the transmission shaft 34 can drive the upper hole cleaning mechanism 5 to clean the gravel or soil inside the slurry outlet 12, and can also drive the vibrating mechanism 4 at the lower end of the transmission shaft 34 to completely eliminate the bubbles generated by the self-compacting slurry inside the hole.

[0050] In this embodiment, a sealing shell 6 is installed on the separating circular plate 2 to seal the area of ​​the hole cleaning mechanism 5, and the plurality of hole cleaning rods 54 are slidably and sealingly connected to the sealing shell 6. The sealing shell 6 is used to prevent the self-compacting slurry from penetrating into the area of ​​the hole cleaning mechanism 5 to prevent the self-compacting slurry from flowing onto the components and solidifying, thereby damaging the components.

[0051] Embodiment three:

[0052] On the basis of the second embodiment, a vibrating mechanism 4 is further installed at the lower end of the driving mechanism 3, and the vibrating mechanism 4 includes a No. 1 connecting disc 41 fixedly installed at the lower end of the transmission shaft 34, and the No. 1 connecting disc 41 is installed with fixed blocks 42 arranged in a ring array, and each of the fixed blocks 42 is installed with a No. 1 connecting frame 43 for connecting the hinge seat 44, and each of the hinge seats 44 is connected to a vibrating rod 45. It should be noted that the vibrating rod 45 is an existing technology and can generate vibration.

[0053] Specifically, the driving mechanism 3 drives the connecting disc No. 1 41 to rotate, the connecting disc No. 1 41 drives the multiple fixed blocks 42 to rotate, each fixed block 42 drives the connecting frame No. 1 43 thereon to rotate, the connecting frame No. 1 43 drives the hinge seat 44 to rotate, the hinge seat 44 drives the vibrating rod 45 thereon to rotate at a uniform speed, and the vibrating rod 45 can generate vibration by itself. At this point, through the uniform rotation of multiple vibrating rods 45, it can be ensured that the self-compacting slurry within the same height range is fully contacted, and the bubbles inside the self-compacting slurry are eliminated through the vibration of the vibrating rod 45, so as to avoid the poor solidification effect with the I-shaped steel and the risk of cracking.

[0054] Embodiment 4:

[0055] On the basis of the third embodiment, a support mechanism 7 is further installed on the outer wall of the grouting tube 1, and the support mechanism 7 includes a protective shell 71 fixedly installed on the side wall of the grouting tube 1. The protective shell 71 protects the internal No. 2 drive motor 72 to prevent falling gravel or soil from hitting the internal No. 2 drive motor 72. The protective shell 71 is installed with the No. 2 drive motor 72, and the output end of the No. 2 drive motor 72 is fixedly installed with a No. 2 driving gear 73, and the No. 2 driving gear 73 is meshed and connected with a transmission gear ring 74, and the transmission gear ring 74 is rotatably connected to the grouting tube 1, and the transmission gear ring 74 is arranged through the protective shell 71. The outer side of the transmission gear ring 74 is also meshed with a plurality of execution gears 75 arranged in a ring array, a bidirectional screw rod 76 is fixedly mounted on the execution gear 75, and the bidirectional screw rod 76 is rotatably mounted on a fixed seat 56 arranged on the side wall of the grouting cylinder 1, and a slider 77 is threadedly connected to the two sections of the bidirectional screw rod 76 that are arranged in opposite directions, and the slider 77 is slidably connected to the inside of the No. 1 slide groove 11 opened on the grouting cylinder 1, a connecting rod 78 is rotatably mounted on the slider 77, and the end of the connecting rod 78 away from the slider 77 is rotatably connected to a needle seat 79, and a pin 710 is fixedly mounted on the needle seat 79.

[0056] The second driving gear 73 drives the transmission gear ring 74 to rotate, and the transmission gear ring 74 drives multiple execution gears 75 meshing with it to rotate, and each execution gear 75 drives the bidirectional screw rod 76 thereon to rotate, and the rotation of the bidirectional screw rod 76 causes the two sliders 77 thereon to move in opposite directions, thereby enabling the connecting rod 78 to rotate, and the lateral distance can be changed, thereby driving the needle seat 79 thereon to move in the horizontal direction, and the needle seat 79 drives the insertion pin 710 to be inserted into the soil on the inner wall of the hole. At this point, when the vibrating mechanism 4 vibrates to eliminate bubbles, the grouting tube 1 is reinforced and fixed by the supporting mechanism 7, thereby reducing the risk of the grouting tube 1 swinging due to the high-frequency vibration of the vibrating rod 45, causing damage or breakage of components, and extending the service life of the equipment.

[0057] Embodiment five:

[0058] On the basis of the fourth embodiment, the grouting equipment also includes a support frame 8 for supporting the grouting tube 1, and a No. 3 driving motor 82 is installed on the support frame 8.

A No. 2 connecting frame 84 is fixedly installed at the lower end of the sliding seat 83, and the No. 2 connecting frame 84 is The lower end is fixedly installed on the top surface of the grouting tube 1. Specifically, by starting the No. 3 driving motor 82 to drive the threaded rod to rotate, and then drive the sliding seat 83 to move up and down along the guide shaft, the sliding seat 83 drives the grouting tube 1 through the No. 2 connecting frame 84 to penetrate into the interior of the hole, thereby changing the original grouting method that requires manual or mechanical pouring of self-compacting slurry from the hole mouth into the hole. The construction speed is relatively slow, resulting in a long contact time between the self-compacting slurry and the cold air during the process of flowing into the hole, and the self-compacting slurry has solidified before being inserted into the steel part.

[0059] In this embodiment, a slurry delivery pipe 13 is installed through the top of the grouting cylinder 1 for connecting to a delivery pump of the self-compacting slurry to deliver the self-compacting slurry to the interior of the grouting cylinder 1 and spray it out through the slurry outlet 12 .
