Technical Field
[0001] This utility model relates to the field of building engineering technology, and in particular to a device for quickly dealing with hole collapse during the drilling of cast-in-place piles. Background Technology
[0002] During the construction of cast-in-place piles, hole collapse often occurs, which seriously affects the construction progress and quality. Existing methods for dealing with hole collapse are inefficient and complicated to operate.
[0003] The inventors believe that the following defects often exist: workers cannot deal with the collapsed hole in time, resulting in partial incompleteness of the column body, affecting the bearing capacity and stability of the pile. At the same time, the collapsed hole may cause difficulties in subsequent concrete pouring, or even make it impossible to complete the pouring. Therefore, in order to address the above problems, a device for quickly dealing with collapsed holes in cast-in-place piles is proposed. Utility Model Content

[0029] Reference Figure 1 and Figure 3 As shown, this utility model provides a technical solution: a device for quickly treating collapsed holes in cast-in-place piles, including a support 1. A cable take-up structure 2 is installed on the surface of the support 1. A cable 3 is rotatably connected to the arc surface of the cable take-up structure 2. A cylinder 6 is fixedly installed at one end of the cable 3. A material pipe 5 is slidably connected inside the cylinder 6. A nozzle is fixedly installed at one end of the material pipe 5. A probe is fixedly installed above the nozzle. A spraying machine 4 is installed at the end of the material pipe 5 away from the nozzle. A sliding hole is opened inside the cylinder 6. An adjustment device 7 is provided on the inner surface of the sliding hole of the cylinder 6. By setting the adjustment device 7, the effect of detecting and treating the collapsed holes in the cast-in-place piles is achieved, avoiding the collapse of the cast-in-place pile. If a hole collapses during grouting, the workers cannot handle it in time, resulting in partial incompleteness of the column body, affecting the pile's bearing capacity and stability. At the same time, the hole collapse may cause difficulties in subsequent concrete grouting, or even prevent grouting from being completed, affecting the workers' work efficiency. To improve the practicality of the device, auxiliary devices 8 are set on both sides of the support 1. By setting the auxiliary devices 8, the support 1 is supported, avoiding the situation where the material pipe 5 is driven by the spraying machine 4 when grouting into the collapsed hole, causing the support 1 to shake and make mistakes, thus affecting the material pipe 5's grouting into the collapsed hole. This improves the practicality of the device.
[0030] The specific settings and functions of its adjustment device 7 and auxiliary device 8 will be described in detail below.
[0031] Reference Figure 2 , Figure 3 and Figure 5 As shown in this embodiment: the adjusting device 7 includes a circular plate 71, which is slidably connected to the inner surface of the sliding hole of the cylinder 6. The surface of the circular plate 71 is fixedly connected to the cable 3. A rotating plate 72 is fixedly connected to the arc surface of the circular plate 71. The rotating plate 72 is rotatably connected to the inner surface of the sliding hole of the cylinder 6. A rotating plate 73 is rotatably connected inside the bracket 1. The rotating plate 73 is slidably connected to the cable 3 and the material pipe 5. The material pipe 5 is a corrugated pipe. A handle 74 is fixedly connected to the surface of the rotating plate 73. Two ball bearings 75 are rotatably connected inside the rotating plate 72. The ball bearings 75 are rotatably connected to the inner surface of the sliding hole of the cylinder 6. By using the ball bearings 75, the circular plate 71 can be easily driven in the cylinder. The internal rotation of cylinder 6 improves the efficiency of repairing collapsed holes. A scraper 76 is fixedly connected to the surface of cylinder 6, and the edges of scraper 76 are rounded. By setting scraper 76, the wall of collapsed holes can be scraped, which facilitates the sliding of cylinder 6 in collapsed holes and improves the practicality of the device. A rotating rod 77 is rotatably connected to the surface of bracket 1. A connecting plate 78 is fixedly connected to one end of rotating rod 77. A threaded rod 79 is inserted into the internal thread of connecting plate 78. One end of threaded rod 79 abuts against rotating plate 73, which achieves the effect of fixing rotation and avoids the rotating plate 73 from rotating when material is sprayed from material pipe 5, thus improving the practicality of the device.
[0032] Reference Figure 4 and Figure 6 As shown, specifically, the auxiliary device 8 includes two U-shaped plates 81, which are fixedly connected to both sides of the support 1. A rotating rod 82 is rotatably connected inside the U-shaped plates 81. A support plate 83 is fixedly connected to the arc surface of the rotating rod 82. Several pointed cones 84 are fixedly connected to the surface of the support plate 83. A fixing groove is opened on the side wall of the support plate 83. A sliding rod 85 is slidably connected inside the fixing groove of the support plate 83. A fixing plate 86 is slidably connected to the arc surface of the sliding rod 85. The fixing plate 86 is fixedly connected to the side wall of the support 1. A pull plate 87 is fixedly connected to one end of the sliding rod 85. The arc surface of the support plate 83 is fitted with a spring 88. The two ends of the spring 88 are fixedly connected to the pull plate 87 and the fixing plate 86, respectively, which achieves the effect of fixing the support plate 83 and prevents the support plate 83 from rotating on the rotating rod 82 during the transportation of the support 1, thus improving the practicality of the device. The arc surface of the rotating rod 82 is fitted with two torsion springs 89. The two ends of the torsion springs 89 are fixedly connected to the support plate 83 and the U-shaped plate 81, respectively. Under the action of the torsion springs 89, the support plate 83 is automatically unfolded, which facilitates the support plate 83 to provide auxiliary support for the support 1, thus improving the practicality of the device.
[0033] The working principle is as follows: When workers need to address a collapsed hole, they first assemble the cylinder 6, the material cylinder, and the cable 3. Then, the cylinder 6 is placed inside the collapsed hole, and workers observe it through a probe. Afterward, the spraying machine 4 is started, and the material is sprayed out from the nozzle through the material pipe 5. The material is collected inside the cylinder 6, achieving the effect of detecting and addressing the hole formation of the cast-in-place pile. This avoids situations where the hole collapses during grouting, preventing workers from addressing the collapse in a timely manner, which could lead to incomplete sections of the pile, affecting the pile's bearing capacity and stability. Furthermore, a collapsed hole could cause difficulties in subsequent concrete grouting, or even prevent grouting from being completed, thus affecting the workers' work efficiency. This improves the practicality of the device.
[0034] When the staff needs to provide auxiliary support for the support 1, pulling the pull plate 87 causes the sliding rod 85 to slide within the fixed plate 86. The sliding rod 85 slides out from the fixed groove of the support plate 83, and the support plate 83 automatically unfolds under the force of the torsion spring 89, so that the pointed cone 84 on the support plate 83 inserts into the ground, achieving the effect of providing auxiliary support for the support 1. This avoids the support 1 from shaking and making mistakes when the material pipe 5 is driven by the spraying machine 4 during the injection of material into the collapsed hole, thus affecting the injection of material into the collapsed hole by the material pipe 5 and improving the practicality of the device.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
