In this process, breaking the pile head has become a key step. As a common process in pile head breaking, the circumferential cutting method is widely used in the construction engineering field. However, due to the high concrete strength when breaking the pile head, manual circumferential cutting takes a long time and the blade is very easy to wear. At the same time, after circumferential cutting, a drill bit is still needed to cut off the pile head. In this process, the drill bit is easy to hit the steel bars, causing damage to the steel bars, and it is time-consuming and laborious. Therefore, there is an urgent need for an auxiliary device to make the circumferential cutting process more time-saving and labor-saving. Summary of the Utility Model

[0024] Embodiment: Please refer to Figure 1 and Figure 2 as shown, which shows a device 10 for assisting in breaking the pile head by the circumferential cutting method in an embodiment. Among them, it includes an isolation ring 1, which is an integral structure or a spliced structure; a plurality of spacers 2, evenly arranged on the inner ring surface of the isolation ring 1; and the isolation ring 1 is provided with an inflation port 3 for injecting a medium into its interior to enhance its strength.
[0025] In this embodiment, the isolation ring 1 is a hollow rubber ring in the shape of a circular ring, the isolation member 2 is a rubber cone, and the cone tips of multiple isolation members 2 all point to the center of the ring of the isolation ring 1 when the isolation ring 1 is inflated and full.
[0026] In this embodiment, the diameter of the isolation ring 1 after installation is the same as the diameter of the pile body 20.
[0027] In this embodiment, both the isolation ring 1 and the isolation member 2 are hollow structures and are interconnected.
[0028] In this embodiment, as Figure 3 shown, in the state where the pile body 20 is being excavated, after discharging the media inside the isolation ring 1 and the isolation member 2, an annular groove 11 and a conical groove 21 with structures consistent with those of the isolation ring 1 and the isolation member 2 are formed on the surface of the pile body 20.
[0029] In this embodiment, the isolation ring 1 and the isolation member 2 are installed on the steel reinforcement cage in advance according to the construction plan.
[0030] In this embodiment, the isolation member 2 is located between two adjacent steel bars of the steel reinforcement cage.
[0031] In this embodiment, multiple isolation members 2 are circumferentially and equidistantly arranged on the inner ring surface of the isolation ring 1.
[0032] In this embodiment, the isolation member 2 is in a conical shape or other structures with a tip and a guiding angle.
[0033] In this embodiment, the structural dimensions of multiple isolation members 2 are all the same, and the extension lines of the top tips are all in the same plane.
[0034] The characteristics and functions of the present utility model can be understood through the following description.
[0035] The device 10 for assisting in breaking the pile head by the circumcision method in this embodiment mainly solves the problems that the traditional breaking of the pile head requires manual chiseling on the surface of the pile body. After chiseling to a certain extent, a drill bit is used to penetrate into the pile body to break and remove the pile head, which is time-consuming and laborious, and it is very easy to cause the fracture of the steel bars while breaking the pile head, resulting in unnecessary losses. However, the device 10 in this embodiment can perfectly solve these problems.
[0036] The device 10 of this embodiment mainly includes an isolation ring 1 made of hollow and elastic rubber material. The isolation ring 1 has an inflation port 3, and an external inflation device can be aligned with the inflation port 3 to inflate the isolation ring 1, so that the expansion strength of the isolation ring 1 becomes harder. At the same time, a plurality of isolation members 2 are evenly distributed at equal intervals in the circumferential direction on the inner ring surface of the isolation ring 1. The isolation members 2 are rubber cones with a conical structure. The isolation members 2 can be hollow structures and communicate with the hollow structure of the isolation ring 1. Therefore, when the external inflation device is aligned with the inflation port 3 to inflate the isolation ring 1, the isolation members 2 can also become harder with increased expansion strength. Of course, in other embodiments, the rubber cones of the isolation members 2 can also be made of solid material, and the solid isolation members 2 are more convenient to install on the steel reinforcement cage.
[0037] The device of this embodiment is composed of an inflatable rubber tube (i.e., the isolation ring 1) and evenly arranged conical rubber cones (i.e., the isolation members 2) on the rubber tube. During use, this device 10 can be assisted in installing on the steel reinforcement cage in advance according to the construction plan. After installation, the diameter of the inflated rubber tube should be the same as the diameter of the bored pile. Then, the rubber tube is inflated through the inflation port 3 to make the rubber tube expand. Later, after the pile head is excavated, the air in the rubber tube is released. Taking advantage of the poor adhesion between rubber and concrete, the device is removed. At this time, a circumferential groove will be directly left at the pile head part of the bored pile, including an annular groove 11 formed by the isolation ring 1 and a conical groove 21 formed by the isolation members 2. The conical groove 21 has a guiding surface, which can facilitate the direct use of a drill bit to break the pile head by penetrating deep into the conical groove 21 in the later stage. It can save the time for workers to break the pile head in the later stage and facilitate construction.
[0038] The device 10 of this embodiment has a simple structure, common production materials, and low cost; the device can be used multiple times through inflation and deflation; it can save the time and accuracy of breaking the pile head; a groove for the drill bit to break is reserved in advance, and the damage to the steel bars is relatively small.
[0039] In summary, the device for assisting in cutting the pile head by the utility model can be installed in the steel reinforcement cage in the early stage of pile head construction, poured together with the pile head, and formed with the pile head. When the device is removed, a circumferential groove will be directly left at the pile head part of the bored pile, and at the same time, a conical groove will be left in the groove. In the later stage, the drill bit can directly penetrate into the conical groove to break the pile head, which can save the time for workers to break the pile head in the later stage and facilitate construction.
[0040] The above is only a preferred embodiment of the utility model, and it does not limit the implementation mode and protection scope of the utility model. For those skilled in the art, it should be realized that all equivalent replacements and obvious changes made by using the description and illustrations of the utility model should be included in the protection scope of the utility model.
