Description

Technical Field

[0001] The utility model belongs to the technical field of concrete piles, and in particular relates to a special-shaped concrete pile. Background Art

[0002] In recent years, precast piles have been widely used in construction projects, municipal projects, transportation projects, wharf projects and river bank protection projects due to their excellent quality, low material cost and fast construction.

[0003] When prefabricated piles are used in river bank protection projects, the pile types include round piles, square piles, prefabricated sheet piles and other special-shaped piles. Round piles and square piles can be processed by centrifugal processing technology to ensure high production efficiency and quality, but when used as bank protection piles, there is no interlocking structure between the piles. On the one hand, it is difficult to control the smoothness of the arrangement between the piles, and on the other hand, the gap between the piles is difficult to control, which can easily cause soil erosion between the piles; prefabricated sheet piles are generally I-shaped structures, and interlocking structures can be set between the piles to ensure smooth and close arrangement between the piles, but they are not suitable for centrifugal processing and can only be produced using fixed table molds, with low production efficiency and low quality assurance rate. Summary of the invention

[0004] The utility model aims at the above problems existing in the prior art and proposes a concrete special-shaped pile which can be produced by a centrifugal method and has a chain structure.

[0005] The utility model can be realized through the following technical solutions:

[0006] A special-shaped concrete pile, characterized by comprising:

[0007] The pile body has two protective surfaces on its front and back sides, and two left and right sides respectively have a first occlusal surface and a second occlusal surface. When the two pile bodies are butted, the first occlusal surface of one pile body contacts the second occlusal surface of the other pile body, wherein:

[0008] The first occlusal surface is provided with an occlusal convex portion, and the second occlusal surface is provided with an occlusal groove. When two adjacent pile bodies are butt-jointed, the occlusal convex portion is inserted into the occlusal groove. At this time, a main pouring area is formed between the occlusal groove and the occlusal convex portion and is used for pouring concrete or grouting.

[0009] As a further improvement of the present invention, the first occlusal surface further has a first abutting end surface, and the second occlusal surface further has a second abutting end surface. When two adjacent pile bodies are occluded, the first abutting end surface abuts against the second abutting end surface.

[0010] As a further improvement of the present invention, the depth of the engagement groove is greater than the protrusion height of the engagement protrusion.

[0011] As a further improvement of the present invention, when the engaging protrusion is inserted into the engaging groove, the main casting area is formed between the bottom surface of the engaging groove and the top surface of the engaging protrusion.

[0012] As a further improvement of the present invention, two sides of the engaging protrusion and the engaging groove are respectively arranged as a first inclined surface and a second inclined surface.

[0013] As a further improvement of the present invention, after the engaging protrusion is inserted into the engaging groove, a distance is left between the first inclined surface and the second inclined surface to form an adjustment gap.

[0014] As a further improvement of the present invention, the first inclined surface and the second inclined surface can be set to have the same slope or different slopes, but the adjustment gap is always connected to the main casting area.

[0015] As a further improvement of the utility model, the front and rear two protective surfaces are arranged as end surfaces protruding outwards, wherein the middle position protrudes outwards more than the two end positions and transitions through an inclined surface.

[0016] As a further improvement of the present invention, the interior of the pile body is configured as a hollow cavity.

[0017] As a further improvement of the utility model, when the pile bodies are sunk, the first pile body may not be provided with a pile tip, and the subsequent pile bodies are all provided with pile tips and the pile tips are welded to the steel plate at the top of the pile, wherein the pile tips have a unidirectional inclined surface.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1. The two adjacent pile bodies are connected by the interlocking convex part and the interlocking groove to form a connected main pouring area and an adjustment gap. By pouring concrete in the main pouring area and the adjustment gap, the connection firmness between the two pile bodies is improved, the adjacent piles are subjected to force in a coordinated manner, and a waterproof effect is achieved, thereby extending the maintenance cycle;

[0020] 2. The depth of the bite groove is greater than the protruding height of the bite convex part. At the same time, the bite convex part and the bite groove are respectively provided with a first inclined surface and a second inclined surface. When the bite convex part is inserted into the bite groove, a main casting area is formed between the bottom surface of the bite groove and the top surface of the bite convex part. A distance is left between the first inclined surface and the second inclined surface to form an adjustment gap, thereby realizing a non-linear arc arrangement between the pile bodies;

[0021] 3. The front and rear protective surfaces are set as outwardly protruding end surfaces, the middle position of which is more protruding than the two ends and transitioned through an inclined surface. This structure facilitates demoulding of the upper and lower molds of the formed pile body;

[0022] 4. The interior of the pile body is set as a hollow cavity, which is convenient for centrifugal molding, improving pile body production efficiency and ensuring quality. BRIEF DESCRIPTION OF THE DRAWINGS

[0031] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical method of the present invention, but the present invention is not limited to these embodiments.

[0032] like Figure 1-2 As shown, the utility model provides a concrete special-shaped pile, comprising:

[0033] The pile body 100 is a prestressed reinforced concrete structure, wherein the prestressed main reinforcement 102 is longitudinally arranged in the high-strength concrete 101 around the pile body 100, and the stirrups 103 and the structural reinforcement 104 are uniformly distributed circumferentially around the outside of the prestressed main reinforcement 102. Steel end plates are arranged at both ends of the pile body 100 as anchorages for the prestressed main reinforcement 102.

[0034] The front and rear surfaces of the pile body 100 are protective surfaces 110, which are water-facing surfaces or soil-facing surfaces. The left and right surfaces of the pile body 100 are respectively a first occlusal surface 120 and a second occlusal surface 130. When two pile bodies 100 are butt-jointed, the first occlusal surface 120 of one pile body 100 is butt-jointed with the second occlusal surface 130 of the other pile body 100.

[0035] The first occlusal surface 120 is provided with an occlusal protrusion 121, and the second occlusal surface 130 is provided with an occlusal groove 131. When two adjacent pile bodies 100 are butt-jointed, the occlusal protrusion 121 is inserted into the occlusal groove 131. At this time, a main pouring area 140 is formed between the occlusal protrusion 121 and the occlusal groove 131 and is used for pouring concrete or grouting. After the concrete is cured and formed, waterproofing and coordinated force are achieved between the two pile bodies 100.

[0036] Because the two adjacent pile bodies 100 are connected by the engaging protrusion 121 and the engaging groove 131 to form the main pouring area 140 and the adjustment gap 150, the connection firmness between the two pile bodies 100 is improved and the maintenance cycle is extended by pouring concrete in the main pouring area 140 and the adjustment gap 150.

[0037] Preferably, the first occlusal surface 120 also has a first abutting end surface 122, and the second occlusal surface 130 also has a second abutting end surface 132. When two adjacent pile bodies 100 are butt-jointed, the first abutting end surface 122 abuts against the second abutting end surface 132. At this time, a main casting area 140 and an adjustment gap 150 can be formed between the occlusal protrusion 121 and the occlusal groove 131.

[0038] Specifically, the depth of the engaging groove 131 is greater than the protruding height of the engaging protrusion 121 . When the engaging protrusion 121 is inserted into the engaging groove 131 , a main casting area 140 is formed between the bottom surface of the engaging groove 131 and the top surface of the engaging protrusion 121 .

[0039] The two sides of the engaging protrusion 121 and the engaging groove 131 are respectively provided with a first inclined surface 1211 and a second inclined surface 1311 . When the engaging protrusion 121 is inserted into the engaging groove 131 , a distance is left between the first inclined surface 1211 and the second inclined surface 1311 to form an adjustment gap 150 .

[0040] The first inclined surface 1211 and the second inclined surface 1311 can be set to have the same slope or different slopes, and are usually set to have the same slope. In this case, the adjustment gap 150 is connected to the main pouring area 140 .

[0041] Therefore, after concrete is poured into the main pouring area 140 and the gap 150 is adjusted, the top surface of the engaging protrusion 121 and the first inclined surfaces 1211 on both sides can be fixedly connected to the engaging groove 131 to improve the firmness of the connection.

[0042] Preferably, the front and rear protective surfaces 110 are configured as outwardly protruding end surfaces, wherein the middle portion protrudes outward more than the two end portions and transitions through an inclined surface. Compared with a planar protective surface 110, this structure of the protective surface 110 further improves the convenience of demolding the pile body 100 during molding.

[0043] Preferably, the interior of the pile body 100 is configured as a hollow cavity 105 to facilitate the use of a centrifugal production process to form the pile, thereby improving labor productivity and ensuring quality.

[0044] Preferably, a prestressed steel bar high-strength concrete structure is prefabricated in the pile body 100 to improve the strength of the entire pile body 100 .
