Description

Technical Field

[0001] This utility model belongs to the field of concrete technology, specifically relating to a concrete wave pile and its pipe mold. Background Technology

[0002] Concrete corrugated piles (hereinafter referred to as corrugated piles) are a new type of concrete component that has become increasingly popular and widely used in recent years. They are extensively applied in water conservancy projects such as bank protection and slope protection, landscape river channel renovation, waterway support, and sheet pile wharves, serving to retain soil, block water, and provide structural support. The unique wave-shaped design of corrugated piles effectively disperses the impact of water flow, enhancing the stability and durability of the structure. They offer high overall cost-effectiveness, boasting advantages such as aesthetic appeal, excellent water-stopping effect, economic efficiency, cost savings, flexible application, and factory production.

[0003] However, existing concrete corrugated piles typically have a semi-circular C-shaped or U-shaped cross-section, which presents some problems during production and use:

[0004] 1. Insufficient structural strength: Traditional U-shaped wave piles are produced in semi-open molds without sufficient prestressed steel tensioning and centrifugal processes. The concrete density is insufficient, resulting in inadequate structural strength. During construction and pile driving or when subjected to large water flow impacts, cracks or even fractures are likely to occur, affecting their service life.

[0005] 2. Complex construction and poor water-stopping effect: Corrugated piles are usually spliced ​​from multiple piles, with adjacent piles connected by tongue and groove joints. Existing tongue and groove joints are generally designed as wedges or squares, requiring precise positioning and installation during construction, which increases the difficulty and cost of construction. The tongue and groove joints are prone to misalignment, which can easily lead to leakage and poor water-stopping effect. Utility Model Content

[0006] The purpose of this utility model is to provide a concrete wave pile and a pipe mold to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a concrete corrugated pile, comprising a pile body, end plate flanges on both sides of the pile body, multiple reinforcing bars connected between the two end plate flanges, the reinforcing bars passing through the pile body, multiple stirrups provided along the length of the reinforcing bars, a flange at the upper end of the pile body, a groove at the lower end, an outer arc surface on the outer side of the pile body, an inner circular surface on the inner side, and inclined surfaces on both sides of the inner circular surface on the pile body.

[0008] The pile body has flat surfaces at both the top and bottom ends, and the flange and groove are provided on the flat surfaces, with the flange and groove being matched and arranged.

[0009] The tube mold for producing concrete corrugated piles includes a lower mold and an upper mold with a symmetrical structure. The lower mold and the upper mold cover each other. The upper and lower tops of the inner cavity of the tube mold are fixed with inner partition plates. Tensioning head plates are provided on the left and right sides of the inner cavity of the tube mold, and inner arc surfaces are provided on the other two sides. The upper and lower ends of the tensioning head plates are opened, and the openings cooperate with the inner partition plates. A rotating shaft is fixed on the outer side of the tensioning head plates and passes through the tube mold. The inner plane of the tube mold is symmetrically provided on the upper and lower sides. The inner plane of the tube mold is provided with a groove and a flange of the inner cavity.

[0010] The inclined surface is divided by an inner partition plate. The inner cavity groove and inner cavity flange of the tube mold correspond to the flange and groove, respectively. The inner arc surface of the tube mold corresponds to the outer arc surface, and the inner plane of the tube mold corresponds to the plane.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] The pile body is reinforced with steel bars and stirrups to enhance its crack resistance, impact resistance and overall strength. The pile body has a U-shaped cross-section with high bending strength.

[0013] The wave-shaped piles have flanges and grooves, both of which are circular. When the piles are spliced, the flanges and grooves interlock with each other, which facilitates quick interlocking and fixing between piles, making the edge structure more robust and less prone to damage from bumps.
