Description

TECHNICAL FIELD

[0001] The utility model belongs to the civil engineering technical field, concretely relates to anchor cable formula vibration high strength composite foundation anti -pulling pile and its construction equipment. BACKGROUND

[0002] In the civil engineering field, the stability of the foundation is the basis of the safety of the building structure, especially in high-rise buildings and heavy industrial facilities, higher requirements are put forward for the anti-pulling performance of the foundation. In these projects, composite foundation anti-pulling piles are widely used to improve the anti-pulling strength of the foundation to ensure the safety and stability of buildings and infrastructure under complex geological conditions. However, there are still some technical problems in the construction and use of traditional anti-pulling piles, which limit their application effect in actual engineering.

[0003] The anti-pulling pile in the prior art usually relies on the simple combination of anchor cable and pile foundation to improve the anti-pulling capacity. However, during construction, the combination of anchor cable and pile foundation may cause the anchor cable to be unevenly distributed in the pile hole, affecting the anti-pulling effect of the anchor cable. In addition, the existing construction equipment structure is relatively simple, lacking an effective support and stabilization system, which causes the equipment to shake or the anchor cable to be unstable during anchor cable setting and concrete pouring, thereby affecting the construction quality of the anti-pulling pile and the use effect in the later period. Therefore, the current composite foundation anti-pulling pile technology needs to be improved to enhance the stability and anti-pulling effect during construction. SUMMARY

[0004] In view of the problems existing in the prior art, the purpose of the utility model is to provide an anchor cable formula vibration high strength composite foundation anti-pulling pile and its construction equipment, which can realize the stability of the construction equipment by setting a fixed frame and stabilizing the fixed frame on the ground by the support leg; at the same time, the anchor body can be smoothly lowered to the bottom of the pile hole through the pulley system, and the vertical stretching state of the anchor body is maintained during concrete pouring, thereby effectively improving the anti-pulling strength and construction efficiency of the composite foundation anti-pulling pile.

[0005] To achieve the above purpose, the utility model provides the following technical scheme:

[0006] An anchor cable formula vibration high strength composite foundation anti-pulling pile, comprising concrete and a reinforcing structure located inside the concrete, the reinforcing structure comprising an anchor shoe and an anchor body;

[0007] The anchor body is bolted to the anchor shoe, and the anchor body is distributed at equal intervals around the central axis of the anchor shoe;

[0008] And the anchor body is in a straight state in the pile foundation concrete;

[0009] The anchor body can be an anchor chain or an anchor rope.

[0010] The utility model provides a kind of construction equipment of anchor cable type vibration high-strength composite foundation anti-pulling pile, including fixed frame, the bottom of the fixed frame is distributed with support leg at equal intervals, and the lower end surface of fixed frame is hung with pulley;

[0011] The number of pulley and anchor body correspond, and anchor body passes through pulley.

[0012] Further, the shape of the fixed frame can be circular or regular polygon, and the cross section of the fixed frame is "H" type.

[0013] Further, the bottom of the fixed frame is fixedly connected with a hanging ring, and the top of the pulley is provided with a hook hung on the hanging ring.

[0014] Further, the number of support legs is three, and the bottom of the support leg is fixedly connected with a foot pad.

[0015] Further, the anchor shoe is inverted conical structure or inverted round table structure.

[0016] Compared with the prior art, the utility model has the beneficial effects that:

[0017] Firstly, the utility model effectively improves the anti-pulling performance of the anti-pulling pile by designing a reasonable reinforcing structure. The combination design of the anchor shoe and the anchor body ensures that the anchor body is distributed at equal intervals around the central axis of the anchor shoe, thereby ensuring that the anchor body is closely arranged in the pile foundation concrete and is in a straight state. This arrangement can significantly improve the bearing capacity of the anti-pulling pile after the concrete is solidified, so that the pile body has higher anti-pulling strength when facing upward pulling force, and solves the problem of unstable stress of traditional anti-pulling piles due to uneven distribution of anchor cables.

[0018] Secondly, the utility model solves the problem of equipment shaking during construction by designing the fixed frame and support legs in the special construction equipment. The support legs at the bottom of the fixed frame can be stably supported on the ground, so that the fixed frame remains stable during construction and prevents shaking, which helps the smooth movement of the anchor body in the vertical direction. The "H" type cross section structure of the fixed frame improves the overall strength of the frame, avoids deformation or instability of the construction equipment under external force, and ensures the stability of the construction quality.

[0019] In addition, the pulley system and hanging design of the utility model improve the smooth lowering effect of the anchor body. During construction, the anchor body passes through the pulley and is hung by the hook and the hanging ring, effectively maintaining the vertical stretching state of the anchor body, ensuring that the anchor body can smoothly sink into the bottom of the pile hole. The design of the pulley and the hook not only avoids the deviation and distortion of the anchor body, but also keeps the anchor body in a stable state during concrete pouring, solving the problem of unsatisfactory anti-pulling effect caused by anchor cable deviation in the prior art.

[0020] Finally, the foot pad design at the bottom of the support leg further improves the stability of the device during construction. The increased contact area of the foot pad with the ground increases the friction of the support leg, preventing the fixed frame from sliding or tilting during construction, thereby ensuring the vertical arrangement of the anchor body and the overall stability of the device. This design effectively solves the problem of displacement of traditional equipment in high-strength operating environments, further improving the safety and reliability of the construction equipment.

[0030] In order to make the purpose and advantages of the utility model more clear and explicit, the utility model will be specifically described below in combination with examples. It should be understood that the following text is only used to describe one or several specific embodiments of the utility model, and does not strictly limit the specific protection scope requested by the utility model.

[0031] Referring to Figures 1-3 , an anchor cable type vibration high-strength composite foundation uplift pile, comprising concrete and a reinforcing structure located inside the concrete, the reinforcing structure comprising an anchor shoe 1 and an anchor body 2; the design structure of the anchor shoe 1 considers the stability and uplift performance at the bottom of the pile foundation, and its surface is thickened to increase the contact area with the bottom of the pile hole; the anchor body 2 is bolted to the anchor shoe 1, and the anchor body 2 is distributed at equal intervals around the central axis of the anchor shoe 1 to form a uniform stress layout; the anchor body 2 is tightly arranged in the pile foundation concrete through chain links, and the whole presents a straight state to ensure that the uplift pile has good uplift capacity after the concrete solidifies; the anchor body 2 maintains a vertical stretching state during the concrete pouring process, and this arrangement structure helps to improve the stability and uplift effect of the anchor body 2 under stress.

[0032] See Figures 1-3 An anchored vibratory high-strength composite foundation anti-tension pile construction device includes a fixed frame 3, which is designed as a robust and durable frame structure to provide sufficient support and stability during construction. Support legs 4 are evenly distributed at the bottom of the fixed frame 3. The design of the support legs 4 ensures that the fixed frame 3 can be stably attached to the ground during installation, thereby avoiding shaking during construction. In addition, pulleys 5 are attached to the lower end of the fixed frame 3 to assist in the smooth lowering of the anchor body 2. The number of pulleys 5 corresponds to the anchor body 2, and the positions of the pulleys 5 are precisely arranged so that each anchor body 2 can pass through the corresponding pulley 5, ensuring the vertical stability of the anchor body 2 and preventing deviation during descent.

[0033] In this embodiment, the pile hole / pile bore can be constructed using a vibratory compactor; the vibratory compactor can be used to press down and send the anchor shoe 1 to the bottom of the pile hole. During subsequent vibratory compaction construction (such as grouting and powder spraying), the construction equipment of the anchor cable type vibratory high-strength composite foundation pull-out pile can ensure the stability of the construction, especially that the anchor body 2 is always in a straight state.

[0034] See Figures 2-3 The shape of the fixing frame 3 can be circular or regular polygonal to adapt to different foundation pile hole shapes; the cross-section of the fixing frame 3 is designed as an "I" shaped structure. This design improves the bending resistance of the fixing frame 3 and effectively enhances its overall strength, so that the fixing frame 3 can still maintain its shape and stability when subjected to external forces, further improving the reliability of the construction equipment during the construction process.

[0035] See Figures 2-3 A hanging ring 31 is fixedly connected to the bottom of the fixed frame 3. The hanging ring 31 is located at the bottom center of the fixed frame 3 to facilitate the suspension and stability of each pulley 5. The top of the pulley 5 is provided with a hook 51 that is attached to the hanging ring 31. Through this attachment method, the pulley 5 can be firmly fixed to the fixed frame 3, ensuring that the anchor body 2 can move smoothly when passing through the pulley 5, thereby reducing the uneven force on the anchor body 2 caused by pulley shaking or position displacement during construction.

[0036] See Figure 2 The number of support legs 4 is set to three, and they are distributed at equal angles at the bottom of the fixed frame 3 to form a stable triangular support structure. The bottom of the support legs 4 is fixedly connected to the foot pads 41, which have a large contact area to increase the friction between the support legs 4 and the ground, ensuring that the construction equipment will not slide or tilt during use, and further improving the stability of the construction equipment during the construction process.

[0037] See Figures 1-2The anchor body 2 can be a chain or a rope to adapt to different uplift requirements; the chain and the rope are subjected to tensile and corrosion-resistant treatment in material to ensure their service life and safety in harsh environments; the overall design of the anchor body 2 considers force uniformity to ensure that the anchor body 2 can effectively improve the uplift capacity of the pile foundation after the construction of the composite foundation uplift pile is completed.

[0038] In some other embodiments, the anchor shoe 1 is a reverse conical structure or a reverse round table structure. In this way, the forward resistance is small.

[0039] The working principle of the utility model is:

[0040] When in use, the axis of the fixed frame 3 is aligned with the axis of the pile hole, and the bottom of the support leg 4 is fixed to the ground to avoid shaking of the fixed frame 3 during use;

[0041] Then the anchor body 2 is passed through the pulley 5, and the hook 51 arranged at the top of the pulley 5 is hung on the hanging ring 31;

[0042] Then the multiple anchor bodies 2 are moved synchronously, so that the anchor shoe 1 can be stably lowered to the bottom of the pile hole;

[0043] Then the concrete is poured into the pile hole, and the anchor body 2 is always kept in a vertical and stretched state during pouring of the concrete.

[0044] The above is only the preferred embodiment of the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, some improvements and refinements can be made without departing from the principle of the utility model, and these improvements and refinements should also be regarded as the protection range of the utility model. The structures, devices and operation methods not specifically described and explained in the utility model are implemented according to the conventional means in the field without special description and limitation.
