Description

Technical Field

[0001] The utility model relates to the technical field of steel sheet pile support construction equipment, and more specifically, to a steel sheet pile water jet hole guiding device. Background Art

[0002] The steel sheet pile support is enclosed by multiple steel sheet piles, and the lower end of each steel sheet pile needs to be driven into the soil to a certain depth. For some hard geological conditions, it is necessary to install a water jet structure on the steel sheet pile to assist in piling. The current common practice is to directly weld a seamless steel pipe on the steel sheet pile and install a water jet nozzle at one end of the seamless steel pipe.

[0003] The steel sheet pile water jet disclosed in Chinese patent applications CN115595972A and CN215759016U generally uses a main water pipe to introduce high-pressure water, and then uses three outlet pipes at the bottom of the pile body to perform high-pressure water flushing for construction.

[0004] Although the structure of the steel sheet pile water jet is simple, the water jet formed by one main water pipe and two or three outlet pipes has a relatively small water pressure and limited cutting effect, resulting in low construction efficiency. On the other hand, the outlet pipe at the bottom is prone to bottom mud penetration when no water is discharged, which affects its service life. At the same time, traditional main water pipes are generally hoses, which makes them inconvenient to fix and easy to break.

[0005] Therefore, it is necessary to propose a steel sheet pile water jet hole guiding device to solve the above problems. Utility Model Content

[0006] The utility model provides a steel sheet pile water jet hole guiding device, which solves the problems of low construction efficiency and short service life of the existing steel sheet pile water jet.

[0007] According to one aspect of the utility model, there is provided a steel sheet pile water jet hole-guiding device, which is installed on a pile body, wherein the steel sheet pile water jet comprises a mounting seat, a protective steel pipe and a protrusion, wherein the protective steel pipe is welded and fixed along the length direction of the pile body, an accommodating cavity is arranged in the mounting seat, and a high-pressure nozzle is opened at the end thereof, a hose connected to the accommodating cavity is built in the protective steel pipe, and a plurality of protrusions arranged at intervals are welded on one side of the pile body close to the high-pressure nozzle.

[0008] Preferably, based on the above solution, the mounting seat is welded to the pile body, and the mounting seat is a stainless steel seat body.

[0009] Preferably, based on the above solution, the number of the high-pressure nozzles is greater than or equal to 4.

[0010] Preferably, based on the above solution, the high-pressure nozzle is located between two adjacent protrusions.

[0011] Preferably, based on the above solution, a rib plate is welded between the mounting seat and the inner side surface of the pile body.

[0012] The utility model discloses a steel sheet pile water jet hole-guiding device, which is achieved by welding a stainless steel mounting seat in the steel sheet pile, providing a accommodating chamber therein, introducing high-pressure water into the steel sheet pile through a hose passed through a protective steel pipe to store energy, and then spraying through a high-pressure nozzle. On the one hand, the steel pipe is protected to avoid the problem of hose damage, and on the other hand, the built-in accommodating chamber of the mounting seat can effectively form the introduced water into a plurality of small outlets, thereby forming a wide-in and narrow-out structure, achieving pressurized water outlet and improving its acting force, and a plurality of protrusions are provided on the pile body, which can effectively reduce the blockage of the high-pressure nozzle by mud and improve its overall service life.
