Abstract
Description
Technical Field
[0001] This utility model relates to the field of steel molds for plastic sheet piles, and more specifically, to a steel mold for plastic sheet piles. Background Technology
[0002] Sheet piles are piles driven (vibrated) into the ground to resist horizontal pressure and water pressure. Commonly used sheet piles are wooden sheet piles and plastic steel sheet piles. Sheet piles are mostly used for cofferdams or seepage prevention in water conservancy projects and are a special support structure for deep foundation pit excavation.
[0003] Traditional sheet pile driving and extraction machines are prone to breakage during construction due to hard soil conditions. Therefore, this utility model provides a steel mold to protect the sheet piles during driving. Utility Model Content
[0004] This utility model provides a plastic steel sheet pile steel mold that can overcome some or more defects of the prior art.
[0005] According to the present invention, a steel mold for plastic sheet piles includes a mold body, the mold body including a steel sheet pile, a recess formed at the steel sheet pile to cooperate with the plastic sheet pile, an installation component detachably provided at the recess, an insertion interval for the end of the plastic sheet pile to be inserted between the installation component and the recess, and multiple clamps detachably provided between the steel sheet pile and the plastic sheet pile for fixing the steel sheet pile and the plastic sheet pile.
[0006] The disclosed steel mold for plastic sheet piles, through the coordinated arrangement of steel sheet piles, installation parts, insertion sections and clamps, enables the plastic sheet piles to fit tightly with the steel sheet piles, providing physical protection for the plastic sheet piles during the piling process and preventing the plastic sheet piles from breaking due to soil hardness and impact.
[0007] Understandably, the combination of the insertion section and the clamps allows the plastic steel sheet piles to be stably installed at the steel sheet pile, ensuring the relative stability between the two during the piling process and preventing displacement or misalignment.
[0008] In use, clamps are used to fix the plastic steel sheet piles to the steel sheet piles, and the driving and pulling machine drives the steel sheet piles in. At the same time, the workers remove the clamps in sequence according to the driving progress. After the piles are driven into the design position, the steel sheet piles are pulled out. Because the clamps are removed, the plastic steel sheet piles lose their connection with the steel sheet piles and remain in the design position, thus completing the plastic steel sheet pile construction.
[0009] Preferably, the sheet pile has multiple through holes for mounting components.
[0010] By detachably setting the mounting component and multiple through holes, the mounting component has a certain adjustment range in the horizontal direction, which can more accurately adjust the position of the plastic steel sheet pile to meet the needs of plastic steel sheet piles of different lengths to adjust the installation position of the mounting component, thereby improving the applicability of this disclosure. At the same time, it forms a limit on the top of the plastic steel sheet pile during piling, which helps the plastic steel sheet pile to be driven into the soil smoothly.
[0011] Preferably, the recess has multiple through slots that are evenly spaced.
[0012] The above structure allows the sheet pile to maintain its strength while reducing its own weight.
[0013] Preferably, the mounting component has a mounting plate corresponding to the through hole, the mounting plate has a mating part that is perpendicular to the recess and mates with the inner wall of the recess, and the mounting plate has a circular hole corresponding to the through hole, the circular hole and the through hole are connected by bolts.
[0014] The mating part, which is perpendicular to the recess, can fit tightly with the inner wall of the recess, providing precise positioning and stable support for the end of the plastic steel sheet pile. At the same time, the corresponding arrangement of the round holes and through holes on the mounting plate allows the installation parts to be installed quickly and accurately, simplifying the installation process and saving installation time.
[0015] Preferably, multiple reinforcing ribs are provided between the mating part and the mounting plate.
[0016] By adding reinforcing ribs, the stability between the mating parts and the mounting plate can be increased, preventing displacement or deformation during the piling process.
[0017] Preferably, a groove is formed at the mounting plate, and the insertion section is formed by the groove and the steel sheet pile.
[0018] The grooves, when used in conjunction with the sheet piles, form an insertion interval, providing a docking space for the ends of the plastic sheet piles. This helps guide the plastic sheet piles to be correctly inserted into the predetermined position, ensuring proper alignment and positioning during the piling process. It also protects the ends of the plastic sheet piles from direct impact during piling, reducing the risk of breakage. Attached Figure Description

[0023] To further understand the content of this utility model, a detailed description of the utility model is provided in conjunction with the embodiments. It should be understood that the embodiments are merely illustrative and not limiting of the utility model.
[0024] Example 1
[0025] Please see Figure 1-4 This embodiment provides a plastic steel sheet pile steel mold, which includes a mold body 100. The mold body 100 includes a steel sheet pile 210. A recess 211 is formed at the steel sheet pile 210 to cooperate with the plastic steel sheet pile. An installation member 220 is detachably provided at the recess 211. An insertion interval 410 is formed between the installation member 220 and the recess 211 for the end of the plastic steel sheet pile to be inserted. A plurality of clamps 110 are detachably provided between the steel sheet pile 210 and the plastic steel sheet pile. The clamps 110 are used to fix the steel sheet pile 210 and the plastic steel sheet pile.
[0026] The present invention discloses a steel mold for plastic sheet piles. Through the coordinated arrangement of steel sheet pile 210, installation component 220, insertion section 410 and clamp 110, the plastic sheet pile and the steel sheet pile 210 are tightly fitted together, providing physical protection for the plastic sheet pile during the piling process and avoiding breakage of the plastic sheet pile due to soil hardness and impact force.
[0027] Understandably, the combination of the insertion section 410 and the clamp 110 allows the plastic steel sheet pile to be stably installed at the steel sheet pile 210, ensuring the relative stability between the two during the piling process and preventing displacement or misalignment.
[0028] In use, the plastic steel sheet pile is fixed to the steel sheet pile 210 using clamp 110. The driving and pulling machine drives the steel sheet pile 210 in. At the same time, the workers remove the clamp 110 in sequence according to the driving progress. After the steel sheet pile 210 is driven into the design position, it is pulled out. Because the plastic steel sheet pile loses its connection with the steel sheet pile 210 after the clamp 110 is removed, it remains in the design position, and the plastic steel sheet pile construction is completed.
[0029] In this embodiment, multiple through holes 212 are formed at the sheet pile 210 for the installation of the mounting component 220.
[0030] By detachably setting the mounting component 220 and multiple through holes 212, the mounting component 220 has a certain adjustment range in the horizontal direction, which can more accurately adjust the position of the plastic steel sheet pile to meet the needs of plastic steel sheet piles of different lengths to adjust the installation position of the mounting component 220, thereby improving the applicability of this disclosure. At the same time, it forms a limit on the top of the plastic steel sheet pile during pile driving, which helps the plastic steel sheet pile to be driven into the soil smoothly.
[0031] In this embodiment, a plurality of through grooves 213 are formed at equal intervals in the recess 211.
[0032] The above structure allows the sheet pile 210 to reduce its own weight while ensuring its strength.
[0033] In this embodiment, the mounting component 220 has a mounting plate 310 corresponding to the through hole 212. The mounting plate 310 is provided with a mating part 320 that is perpendicular to the recess 211 and mates with the inner wall of the recess 211. A circular hole corresponding to the through hole 212 is formed on the mounting plate 310. The circular hole and the through hole 212 are connected by bolts.
[0034] The mating part 320, which is perpendicularly arranged between the mounting plate 310 and the recess 211, can closely fit the inner wall of the recess 211, providing precise positioning and stable support for the end of the plastic steel sheet pile. At the same time, the corresponding arrangement of the round hole and the through hole 212 on the mounting plate 310 allows the mounting part 220 to be installed quickly and accurately, simplifying the installation process and saving installation time.
[0035] In this embodiment, a plurality of reinforcing ribs 340 are provided between the mating part 320 and the mounting plate 310.
[0036] By adding reinforcing ribs 340, the stability between the mating part 320 and the mounting plate 310 can be increased, preventing displacement or deformation during the piling process.
[0037] In this embodiment, a groove 330 is formed at the mounting plate 310, and the insertion section 410 is formed by the groove 330 and the steel sheet pile 210.
[0038] The groove 330, in conjunction with the sheet pile 210, forms an insertion interval 410, providing a docking space for the end of the plastic steel sheet pile. This helps guide the plastic steel sheet pile to be correctly inserted into the predetermined position, ensuring its correct alignment and positioning during the piling process. It also protects the end of the plastic steel sheet pile from direct impact during piling, reducing the risk of breakage.
[0039] It is readily understood that those skilled in the art can combine, split, or reorganize the embodiments provided in this application to obtain other embodiments, all of which do not exceed the protection scope of this application.
[0040] The present invention and its embodiments have been described above illustratively. This description is not restrictive, and the embodiments shown are only part of the embodiments of the present invention. The actual structure is not limited to this. Therefore, if those skilled in the art are inspired by this description and design similar structures and embodiments without departing from the inventive spirit of the present invention, such designs should fall within the protection scope of the present invention.
