Abstract
Description
Technical Field
[0001] The utility model relates to the field of anti-floating anchor piles, in particular to an anti-floating anchor pile for a large underground structure. Background Art
[0002] The anti-floating measures for structures in engineering projects mainly include adding counterweights, anti-floating anchor rods and anti-floating piles. The adding counterweights method is to backfill materials with larger bulk density on the foundation slab and surrounding areas or increase the deadweight of the structure to resist water buoyancy. When the anti-floating water level is high, it is neither economical nor feasible to use only the adding counterweights method. Anti-floating anchor rods are a common solution for structural anti-floating design because they can be flexibly arranged on the foundation slab and are economical.
[0003] Most of the existing anti-floating anchor rods are made by welding multiple groups of steel bars together to form anchor rod steel bars, and clamping grouting pipes on their outer walls. Subsequently, a machine is used to impact the ground to form a borehole, and the anchor rod steel bars and the grouting pipes are placed inside the borehole together. Then, workers pour concrete into the borehole through the grouting pipe. When the concrete group overflows the borehole, the injection is stopped. At the same time, the grouting pipe on the anchor rod steel bars is pulled out of the borehole by a machine during the pouring process, thus completing the installation of the anti-floating anchor rod.
[0004] To sum up, when the anchor steel bars are placed inside the drilled hole in the above structure, due to the long length of the anchor steel bars themselves, it is very easy to cause the upper anchor steel bars to tilt during the pouring of concrete, thereby affecting the subsequent use of the anti-floating anchor rod, and the pouring process is not in a sealed state, so a large amount of gas will remain inside the poured concrete, affecting the subsequent concrete pouring quality. Utility Model Content
[0005] Based on this, the purpose of the utility model is to provide a large underground structure anti-floating anchor pile to solve the problem that the upper anchor steel bars are easily tilted during the pouring of concrete, thereby affecting the subsequent use of the anti-floating anchor, and a large amount of gas will remain inside the poured concrete, affecting the subsequent concrete pouring quality.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a large underground structure anti-floating anchor pile, including anchor rods and steel bars, the anchor rods and steel bars are detachably provided with a sac body on the outer wall, a pouring port is penetrated through the top of the sac body, a bracket is provided at the bottom of the sac body at the pouring port, and a rotating wheel is rotatably provided on the inner wall of the bracket.
[0007] By adopting the above technical scheme, the grouting pipe is connected to the pouring port on the top of the bladder, and then the bladder and the anchor steel bar are placed inside the borehole together. The bladder contacts the inner wall of the borehole to ensure that the anchor steel bar is always in a vertical state. During the pouring process, the bladder moves upward together with the grouting pipe, so that the upper part of the anchor steel bar will not tilt during pouring, thereby ensuring the subsequent use effect of the anti-floating anchor rod, and a runner is provided at the pouring port at the bottom of the bladder. During the pouring process, the runner will rotate together to discharge the air inside the concrete in the borehole, effectively reducing the air retained in the concrete, and further improving the subsequent concrete pouring effect.
[0008] The utility model is further configured that the outer walls of the capsule are connected via lock buckles.
[0009] By adopting the above technical solution, the bladder can be easily installed on the outer wall of the anchor steel bar under the action of the lock, and the staff can easily disassemble the bladder by hand, so that the bladder can be reused, thereby improving the overall practicality of the bladder.
[0010] The utility model is further configured that the outer wall of the capsule body is provided with a plurality of pulleys for sliding up and down.
[0011] By adopting the above technical solution, the sliding mode of the bladder can be changed easily through the action of the pulley, and the sliding friction between the bladder and the borehole can be changed into rolling friction. In the process of the grouting pipe moving upward, it is easy to drive the bladder to slide out of the borehole, and further prevent the grouting pipe from breaking during the upward movement, thereby improving the overall service life of the device.
[0012] The utility model is further configured such that the contact surface between the inner wall of the bladder and the anchor steel bar is configured to be rough.
[0013] By adopting the above technical solution, the rough setting between the two makes it easy to increase the sliding friction between the two. When the bladder and the anchor steel bar are placed inside the drilled hole together, it is ensured that the bladder will not slide downward due to its own gravity, thereby ensuring the stability of subsequent concrete pouring.
[0014] The utility model is further configured that a clamping structure is provided on the top of the pouring port.
[0015] By adopting the above technical solution, the grouting pipe and the pouring port can be easily spliced through the clamping structure, thereby ensuring the sealing of the connection between the two, further preventing concrete leakage during the pouring process, and effectively reducing concrete waste.
[0016] The utility model is further configured that the outer wall of the pulley is configured to be smooth.
[0017] By adopting the above technical solution, during the upward sliding process of the grouting pipe, the smooth setting of the outer wall of the pulley facilitates to reduce the sliding friction between the pulley and the borehole, further ensuring that the bladder can slide out smoothly from the inside of the borehole.
[0018] The utility model is further configured that the bottom of the anchor steel bar is configured in a conical shape.
[0019] By adopting the above technical solution, when the anchor rod reinforcement is placed inside the drilled hole, the conical setting of the bottom facilitates fixing the bottom of the anchor rod reinforcement inside the drilled hole.
[0020] The utility model is further configured that the rotating wheel is located at an eccentric position of the pouring port.
[0021] By adopting the above technical solution, when concrete passes through the pouring port, it will impact one side of the wheel. Since the wheel is located at an eccentric position of the pouring port, the concrete will drive the wheel to rotate in one direction all the time, ensuring the exhaust effect inside the concrete.
[0022] In summary, the utility model mainly has the following beneficial effects:
[0023] The utility model has a bladder body detachably provided on the outer wall of the anchor steel bar, and a grouting pipe is connected to the pouring port on the top of the bladder body, and then the bladder body and the anchor steel bar are placed inside the borehole together. The bladder body contacts the inner wall of the borehole to ensure that the anchor steel bar is always in a vertical state. During the pouring process, the bladder body moves upward together with the grouting pipe, so that the upper part of the anchor steel bar will not tilt during pouring, thereby ensuring the use effect of the subsequent anti-floating anchor rod, and a rotating wheel is provided at the pouring port at the bottom of the bladder body. During the pouring process, the rotating wheel will rotate together to discharge the air inside the concrete in the borehole, effectively reducing the air retained in the concrete, and further improving the subsequent concrete pouring effect.

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. The embodiments described below with reference to the drawings are exemplary and are only used to explain the utility model, and cannot be understood as limiting the utility model.
[0031] The following describes an embodiment of the utility model based on its overall structure.
[0032] Embodiment 1
[0033] A large underground structure anti-floating anchor pile, such as Figure 1-Figure 4 As shown, it includes an anchor steel bar 1, a bladder 2, a sliding mechanism and an exhaust mechanism. A hole is drilled in a designated area by a machine, and then the outer wall of the bladder 2 is connected by a lock buckle 7. Under the action of the lock buckle 7, the bladder 2 is conveniently installed on the outer wall of the anchor steel bar 1. The staff can easily disassemble the bladder 2 through the lock buckle 7, so that the bladder 2 can be reused, thereby improving the overall practicality of the bladder 2. At the same time, a pouring port 3 is provided through the top of the bladder 2, and a clamping structure is provided on the top of the pouring port 3. The clamping structure is convenient for splicing the grouting pipe and the pouring port 3 to ensure the sealing of the connection between the two, further preventing the phenomenon of concrete leakage during the pouring process, and effectively reducing the waste of concrete. The staff places the anchor steel bar 1 and the bladder 2 in the drilled hole, and the bladder 2 contacts the inner wall of the drilled hole to ensure that the anchor steel bar 1 is always in a vertical state. During the pouring process, the bladder 2 moves upward together with the grouting pipe, so that the upper part of the anchor steel bar 1 will not tilt during pouring, thereby ensuring the use effect of the subsequent anti-floating anchor.
[0034] A bracket 4 is provided at the bottom of the bladder 2 at the pouring port 3, and a rotating wheel 5 is rotatably provided on the inner wall of the bracket 4, wherein the rotating wheel 5 is located at an eccentric position of the pouring port 3, and when concrete passes through the pouring port 3, it will impact one side of the rotating wheel 5. Since the rotating wheel 5 is located at the eccentric position of the pouring port 3, the concrete will drive the rotating wheel 5 to rotate in one direction all the time, and the air inside the concrete in the drilled hole will be discharged, thereby effectively reducing the air retained in the concrete and further improving the subsequent concrete pouring effect.
[0035] See also Figure 1 and Figure 3The contact surface between the inner wall of the bladder 2 and the anchor steel bar 1 is roughened, and the roughened surface between the two is convenient for increasing the sliding friction between the two. When the bladder 2 and the anchor steel bar 1 are placed inside the borehole together, it is ensured that the bladder 2 will not slide downward due to its own gravity, thereby ensuring the stability of subsequent concrete pouring. At the same time, the bottom of the anchor steel bar 1 is conical. When the anchor steel bar 1 is placed inside the borehole, the conical setting of the bottom facilitates fixing the bottom of the anchor steel bar 1 inside the borehole.
[0036] Embodiment 2
[0037] See also Figure 5 A large underground structure anti-floating anchor pile is shown, and its overall structure is similar to that of Example 1, wherein an array of pulleys 6 are provided on the outer wall of the sac 2 for sliding up and down. The pulley 6 is used to change the sliding mode of the sac 2, and the sliding friction between the sac 2 and the borehole is changed into rolling friction. In the process of the grouting pipe moving upward, the sac 2 is driven to slide out of the borehole, and the grouting pipe is further prevented from breaking during the upward movement, thereby improving the overall service life of the device. In addition, the outer wall of the pulley 6 is smoothly arranged. In the process of the grouting pipe sliding upward, the smooth setting of the outer wall of the pulley 6 is convenient to reduce the sliding friction between the grouting pipe and the borehole, thereby further ensuring that the sac 2 can slide out smoothly from the inside of the borehole.
[0038] The working principle of the utility model is as follows: when in use, a designated area of the ground is drilled by a machine, and a worker clamps the bladder 2 on the anchor steel bar 1, and connects it to the pouring port 3 on the top of the bladder 2 through a grouting pipe, and then places it inside the borehole, and injects concrete into the borehole through the grouting pipe. Under the action of the bladder 2, the verticality of the anchor steel bar 1 is ensured, and the grouting pipe is lifted upward. During this process, the grouting pipe will drive the bladder 2 to move upward together. During the upward movement of the bladder 2, the upper part of the anchor steel bar 1 will not tilt, and at the same time, the concrete flowing out of the pouring port 3 will drive the runner 5 to rotate. During the pouring process, the runner 5 will discharge the air inside the concrete in the borehole, effectively reducing the air retained in the concrete.
[0039] Although an embodiment of the utility model has been shown and described, this specific embodiment is merely an explanation of the utility model and is not a limitation of the utility model. The specific features, structures, materials or characteristics described may be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art may make modifications, substitutions and variations to the embodiments without creative contributions as needed without departing from the principles and purpose of the utility model. However, as long as they are within the scope of the claims of the utility model, they are protected by patent law.
