Therefore, the terms describing the positional relationship in the drawings are only used for illustrative purposes and cannot be understood as limitations on this patent. For ordinary technicians in this field, the specific meanings of the above terms can be understood according to specific circumstances.

[0025] Reference Figure 1-4 As shown, it is a preferred embodiment provided by the utility model.

[0026] The utility model provides a detachable steel sheet pile plug structure which is convenient for the steel sheet pile to be inserted into the soil layer, comprising a longitudinally arranged steel sheet pile 100 and a plug 200, wherein the bottom of the steel sheet pile 100 is fixedly connected to the plug 200 via a detachable fixing structure, the bottom of the steel sheet pile 100 is embedded in the plug 200, the top of the plug 200 is connected to the bottom of the steel sheet pile 100, and the bottom of the plug 200 is pointed.

[0027] The plug 200 structure of the steel sheet pile 100 provided above is detachable and convenient for the steel sheet pile 100 to be lowered into the soil layer. The plug 200 can reduce the soil resistance during the construction process of the steel sheet pile 100, making the pile body enter the soil more quickly and labor-saving, thereby shortening the construction period and expanding the application scope of the steel sheet pile 100 support. In addition, the plug 200 can be disassembled by disassembling the fixed structure to achieve recycling.

[0028] Specifically, the top of the plug 200 has a reserved groove 220 formed in a concave shape, and the bottom of the steel sheet pile 100 is embedded in the reserved groove 220. In this way, the connection between the plug 200 and the steel sheet pile 100 is achieved through the reserved groove 220.

[0029] The plug 200 has a screw hole 210 that passes through the plug 200 from front to back, and the middle of the screw hole 210 is connected to the reserved groove 220;

[0030] The fixing structure includes a fixing screw and a fixing nut. The middle part of the fixing screw passes through the screw hole 210 and penetrates into the plug 200. The end of the fixing screw passes through the plug 200 to form an extension section, and the fixing nut fixes the extension section. The middle part of the fixing screw passes through the reserved groove 220 and the steel sheet pile 100 embedded in the reserved groove 220. In this way, the plug 200 and the steel sheet pile 100 are fixed to each other through the action of the fixing screw and the fixing nut.

[0031] Furthermore, a reserved hole for the fixing screw to pass through is provided on the bottom of the steel sheet pile 100, and the reserved hole is arranged front and back aligned with the screw hole 210. In this way, the installation and fixing of the fixing screw are facilitated by the function of the reserved hole.

[0032] The front and rear ends of the plug 200 are respectively provided with inclined surfaces 201, on which screw holes 210 are arranged, and along the direction from the top to the bottom of the plug 200, the inclined surfaces 201 are arranged to extend radially inwardly. In this way, the structure is more conducive to breaking the soil, so that the soil is squeezed and broken toward both sides along the inclined surfaces 201.

[0033] Specifically, the plug 200 is triangular in shape, the cross section of the plug 200 is a quadrilateral, and the longitudinal section of the plug 200 is a triangle. In this way, the structure is more conducive to breaking the soil and improving the soil entry efficiency.

[0034] The two sides of the plug 200 are respectively provided with two oppositely arranged triangular surfaces 202, and the two sides of the reserved groove 220 respectively penetrate the triangular surfaces 202, and the bottom of the reserved groove 220 is recessed and extends to the middle of the plug 200. In this way, the reserved groove 220 penetrates the plug 200 horizontally, which facilitates the installation between the plug 200 and the steel sheet pile 100. The bottom of the steel sheet pile 100 can be directly inserted into the plug 200 by simply moving the plug 200.

[0035] The middle of the reserved groove 220 is in a straight line to form a middle section 211, and the two ends of the middle section 211 extend outwardly away from the middle section 211 to form an inclined section 212, and the end of the inclined section 212 penetrates the triangular surface 202. In this way, this multi-section bending structure increases the connection structure between the plug 200 and the steel sheet pile 100, making the connection more stable and reliable.

[0036] The two inclined sections 212 are symmetrically arranged on both sides of the middle section 211. In this way, the structure shape of the Larsen plate is adapted.

[0037] Specifically, the steel sheet pile 100 is composed of a plurality of interconnected Larsen steel plates.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
