Device and method for punching holes in geotextile filter membrane

Abstract

The invention discloses a device and method for punching holes in a geotextile filter membrane, which comprises a vehicle frame, a pressure bearing platform is fixed on the vehicle frame, and a pressure bearing platform is provided with piercing holes; a pressure plate is arranged above the pressure bearing platform, and the bottom of the pressure plate is connected with a The top of the pressing plate is connected with a reciprocating mechanism, which includes a moving rod. The bottom of the moving rod is connected with the pressing plate. A sliding sleeve is provided outside the moving rod. A spring is connected to the wall of the moving rod. The bottom of the spring is connected to the sliding seat. Connected, the top of the moving rod is hinged with a connecting rod, the top of the connecting rod is hinged with a rotating rod, and the rotating rod is connected with a fixed column; the top of the slide seat is connected with a vertical plate; the vertical plate is equipped with a motor, and the motor shaft of the motor is fixedly connected There is a shaft sleeve, and a driving rod is connected to the outer wall of the shaft sleeve; a rotating ring is also connected to the vertical plate, and the rotating ring is sleeved outside the motor shaft; one end of the rotating rod is connected with the rotating ring. The invention has the advantages of simple structure and convenient operation, can quickly realize the hole piercing operation of the geotextile, and has high efficiency and good quality.

Description

technical field [0001] The invention relates to the technical field of geotextiles, in particular to a hole-punching device and method suitable for large-aperture geotextile filter membranes. Background technique [0002] Geotextile, also known as geotextile, is a permeable geosynthetic material made of synthetic fibers through needle punching or weaving. It is widely used in plastic drainage plate filter membranes. The water permeability of the geotextile filter membrane is related to the permeable pore size of the filter membrane. The traditional production process of the geotextile filter membrane can only ensure that the filter pores of the filter membrane are between 20 and 30 μm, and the requirement for a larger pore size cannot be achieved. Therefore, in the soft foundation consolidation project, it is difficult to choose a plastic drainage plate filter membrane that is suitable for the actual project, especially a filter membrane with a large pore size, which will af...

Problems solved by technology

The water permeability of the geotextile filter membrane is related to the permeable pore size of the filter membrane. The traditional production process of the geotextile filter membrane can only ensure that the filter pores of the filter membrane are between 20 and 30 μm, and the requirement for a larger pore size cannot be achieved.

Therefore, in the soft foundation consolidation project, it is difficult to choose a plastic drainage plate filter membrane that is suitable for the actual project, especially a filter membrane with a large pore size, which will affect the project quality, delay the project cycle, and increase the project cost.

After retrieval, the Chinese invention patent with the application number 2019202239354 discloses a large-aperture geotextile filter membrane piercing equipment. Although the above-mentioned device can punch holes in the geotextile according to the needs of the site, the device uses a pneumatic lifting rod to realize piercing. As we all know, the pneumatic lifting rod is a multi-section telescopic rod with the cylinder as the core. After a hole piercing effect, it is necessary to separate the hole piercing column from the hole piercing for the next piercing. The piercing post cannot be automatically reset. , the efficiency of piercing holes is low, and it cannot form an effective flow operation
