Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to an interlocking bored pile-wall structure with seepage prevention function. Background Technology

[0002] Drilled piles are a type of deep foundation commonly used in construction engineering, typically to support large buildings, bridges, and other heavy structures. By drilling and pouring concrete deep into the ground, drilled piles provide strong support for the superstructure. They are suitable for projects with complex soil conditions and significant depths, exhibiting excellent bearing capacity and stability.

[0003] Traditional bored piles typically consist of a drill bit, pile casing, concrete, and reinforcing steel. The drill bit is responsible for drilling a hole in the ground, while the pile casing is used to maintain the stability of the borehole and prevent the borehole wall from collapsing. When concrete is poured into the hole, the reinforcing steel plays a role in enhancing the load-bearing capacity and ensuring the strength and stability of the pile.

[0004] Traditional bored piles are ineffective at preventing seepage, mainly due to the poor stability of the borehole wall during the grouting process. This can easily lead to poor contact between the concrete and the soil, resulting in tiny cracks or voids. These cracks or voids become channels for water seepage, allowing groundwater to enter and affecting the stability and durability of the pile foundation. Ultimately, this can cause settlement or structural damage to the building. Summary of the Invention

[0005] To overcome the above shortcomings, this utility model provides an interlocking bored pile-wall structure with seepage prevention function, which aims to improve the problem of poor seepage prevention of traditional bored piles leading to groundwater ingress and affecting the stability and durability of the pile foundation.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an interlocking bored pile-wall structure with seepage prevention function, comprising: The pile body, which forms the foundation of the bored cast-in-place pile, has a seepage prevention component installed on its outer wall. The anti-seepage protrusions, with their sidewalls fixedly connected to the sidewalls of the pile body, are provided. The seepage prevention component includes seepage prevention grooves, and multiple seepage prevention grooves are formed on the other side of the pile body. The seepage prevention grooves and the seepage prevention protrusions form an interlocking seepage prevention mechanism. The pile body is equipped with a reinforcement component, which is used to support the pile body. The pile body is equipped with reinforcement components.

[0007] As a further description of the above technical solution: The anti-seepage protrusion and the anti-seepage groove engage with each other, and the cross-sections of the anti-seepage protrusion and the anti-seepage groove are trapezoidal.

[0008] As a further description of the above technical solution: Both the surface of the pile body and the surface of the anti-seepage protrusion are provided with an anti-seepage layer, which is used for surface waterproofing.

[0009] As a further description of the above technical solution: A water-stop strip is fixedly connected between the plurality of the seepage-proof protrusions, and the water-stop strip is used to seal the interlocking parts.

[0010] As a further description of the above technical solution: The reinforcement component includes a steel cage, which is disposed inside the pile body.

[0011] As a further description of the above technical solution: The steel cage has multiple longitudinal main bars fixedly connected inside, and multiple annular stirrups fixedly connected to the outer wall of the longitudinal main bars.

[0012] This utility model has the following beneficial effects: 1. In this utility model, firstly, the seepage path is blocked by the trapezoidal interlocking of the seepage-proof protrusion and the seepage-proof groove between adjacent piles. The seepage-proof layer on the surface of the pile and the seepage-proof protrusion enhances the surface waterproofing. The water-stop strip between the seepage-proof protrusions seals the interlocking gap. The multiple seepage-proof design solves the problem of poor seepage prevention of traditional bored piles and prevents the pile from becoming unstable and damaged due to seepage.

[0013] 2. In this utility model, the longitudinal main reinforcement of the steel cage inside the pile bears the force and the circumferential stirrups restrain the lateral deformation, thereby improving the pile's fracture resistance and enhancing its bearing capacity, and meeting the dual requirements of the support structure for seepage prevention and stability.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Reference Figures 1-3 One embodiment of this utility model is a type of interlocking bored pile-wall structure with seepage prevention function, comprising: Pile 1, which forms the foundation of the bored cast-in-place pile, has an anti-seepage component installed on its outer wall. The anti-seepage protrusion 2 engages with the anti-seepage groove 3 of the adjacent pile body 1. The trapezoidal cross-section of both protrusions results in a larger interlocking contact surface and a tighter fit, achieving the effect of forming a continuous interlocking anti-seepage barrier and blocking groundwater from seeping through the gaps in the pile body 1. The sidewalls of multiple anti-seepage protrusions 2 are fixedly connected to the sidewalls of the pile body 1. The seepage prevention component includes seepage prevention grooves 3. Multiple seepage prevention grooves 3 are formed on the other side of the pile body 1. The seepage prevention grooves 3 and the seepage prevention protrusions 2 form an interlocking seepage prevention system. The pile body 1 is equipped with a reinforcement component. The anti-seepage protrusion 2 and the anti-seepage groove 3 interlock with each other. The cross-sections of the anti-seepage protrusion 2 and the anti-seepage groove 3 are trapezoidal. Both the surface of the pile body 1 and the surface of the anti-seepage protrusion 2 are provided with an anti-seepage layer 4. The anti-seepage layer 4 is a cement-based penetrating crystalline waterproof coating layer or a polymer cement waterproof coating layer. Its function is to form a dense waterproof membrane on the surface of the pile body 1 and the surface of the anti-seepage protrusion 2, preventing groundwater from seeping into the interior of the pile body 1 from the structural surface. This is common knowledge and will not be elaborated further here. The anti-seepage layer 4 is used on the surface. Waterproof, multiple seepage-proof protrusions 2 are fixedly connected with waterstop strips 8, the waterstop strips 8 seal the interlocking gaps between multiple seepage-proof protrusions 2, thereby filling the tiny gaps that may exist when interlocking, preventing groundwater from seeping from the gaps, and further enhancing the seepage-proof sealing of the interlocking parts. The waterstop strips 8 are used to seal the interlocking parts. The reinforcement components include a steel cage 5, which is set inside the pile body 1. Multiple longitudinal main bars 6 are fixedly connected inside the steel cage 5, and multiple annular stirrups 7 are fixedly connected to the outer wall of the longitudinal main bars 6.

[0018] Working principle: The steel cage 5 bears longitudinal force through multiple longitudinal main bars 6 fixedly connected internally, and multiple annular stirrups 7 fixedly connected to the outer wall constrain the lateral deformation of the longitudinal main bars 6. Together, they enhance the structural strength and deformation resistance of the pile body 1, ensuring that the pile body 1 is not easy to break under stress. Between adjacent pile bodies 1, multiple anti-seepage protrusions 2 fixedly connected to one side wall and multiple anti-seepage grooves 3 opened on the other side wall interlock with each other to form an interlocking connection to block the seepage path. At the same time, the anti-seepage layer 4 set on the surface of the pile body 1 and the surface of the anti-seepage protrusions 2 further enhances the surface waterproof performance. The waterstop strips 8 fixedly connected between the multiple anti-seepage protrusions 2 seal the interlocking parts and fill the interlocking gaps, jointly preventing groundwater from seeping from the gaps or surface of the pile body 1, ultimately achieving both anti-seepage effect and structural bearing capacity.
