Description

Technical Field

[0001] The utility model relates to the field of slope reinforcement, and more specifically, to a D-shaped precast concrete sheet pile. Background Art

[0002] A sheet pile, also known as a retaining wall, is a precast concrete and steel structure and belongs to a type of protective pile, which can be used for the protection of slopes, foundation pits, etc. Generally, it is driven in by dynamic compaction.

[0003] The current sheet pile structure is plate-shaped or column-shaped, with a relatively single structure, poor support for the soil body, a smooth surface, insufficient resistance between the soil body, and it is prone to settlement deviation over time. Moreover, the bottom is flat, and the resistance to driving into the soil is large. Therefore, the sheet pile structure needs to be improved. Summary of the Utility Model

[0004] Aiming at the problems existing in the prior art, the purpose of the utility model is to provide a D-shaped precast concrete sheet pile, which can increase the friction coefficient with the soil body and avoid settlement deviation.

[0005] To solve the above problems, the utility model adopts the following technical solutions.

[0006] A D-shaped precast concrete sheet pile includes a concrete pile body and a steel bar framework. The concrete pile body is poured on the outside of the steel bar framework, and the concrete pile body includes a bearing arch surface and a supporting straight surface. The side of the bearing arch surface is evenly provided with damping grooves, and the bottom opening of the damping groove is larger than the top opening.

[0007] Furthermore, the bottom steel bars of the steel bar framework are bent and spliced to form a conical head, and the conical head is fixed by welding after being spliced by the steel bars.

[0008] Furthermore, one side of the supporting straight surface is provided with a docking protrusion, and the other side of the supporting straight surface is provided with a docking groove.

[0009] Furthermore, the docking groove and the docking protrusion are adapted to each other.

[0010] Compared with the prior art, the advantages of the utility model are as follows:

[0011] (1) The sheet pile of this scheme adopts a D-shaped structure, with a bearing arch surface on one side and a supporting straight surface on the other side, which can bear greater pressure. Damping grooves are opened on the outside of the bearing arch surface, which can increase the friction coefficient with the soil body, avoid settlement deviation, and at the same time, the bottom opening of the damping groove is large and the top opening is small, which is convenient for the concrete pile body to be driven into the soil.

[0012] (2) The bottom end of the steel bar framework in this scheme is provided with a conical head, which reduces the resistance of the concrete pile body to be driven into the soil and has stronger practicability. Brief Description of the Drawings

[0019] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model; obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4 , a D-shaped precast concrete sheet pile, comprising a concrete pile body 101 and a steel bar framework 104. The concrete pile body 101 is poured on the outside of the steel bar framework 104, and the concrete pile body 101 includes a bearing arch surface 102 and a supporting straight surface 103. A damping groove 121 is evenly opened on one side of the bearing arch surface 102, and the bottom opening of the damping groove 121 is larger than the top opening. Such a setting not only increases the friction coefficient between the concrete pile body 101 and the soil, but also facilitates the driving of the concrete pile body 101 into the soil.

[0021] Refer to Figures 1-4 , the bottom-end steel bars of the steel bar framework 104 are bent and spliced to form a conical head 141, and the conical head 141 is fixed by welding after being spliced by the steel bars. Such a setting facilitates the driving of the concrete pile body 101 into the soil.

[0022] Refer to Figures 1-4 , a docking protrusion 131 is arranged on one side of the supporting straight surface 103, and a docking groove 132 is opened on the other side of the supporting straight surface 103. Such a setting facilitates the splicing and docking between the concrete pile bodies 101.

[0023] Refer to Figures 1-4, the docking groove 132 and the docking protrusion 131 are adapted to each other. Such a setting facilitates the splicing and docking between the concrete pile bodies 101.

[0024] During use: First, hoist the sheet pile as a whole onto the slope to be driven, and adjust the concrete pile body 101 to be parallel to the slope. During the process of dynamically compaction and driving the sheet pile into the soil, ensure that the docking protrusion 131 of the driven sheet pile is spliced with the docking groove 132 of another sheet pile.
