A kind of permeable concrete joint cutting device and using method thereof

Abstract

The invention relates to a pervious concrete cutter and a using method thereof. The water-permeable concrete cutter comprises a round knife, steel wheels, a stop bolt, a bracket, a support frame, a telescopic rod and a handle, wherein the handle is connected to the support frame through the telescopic rod, the support frame is connected to the bracket; along the axis direction of the round knife, the steel wheels are mounted on both sides of the round knife symmetrically, and the steel wheels and the round knife are screwed together through threads. The other ends of the steel wheels are mounted on the bracket by means of the stop bolt, and when the handle is pushed, the round knife and the steel wheels are free to roll. The steel wheels and the round knife can be assembled as a cutting mechanism, and the stop bolt passes through a casing, and is fixed and screwed with the cutting mechanism. In the walking, the round knife cuts, the steel wheels compacts pavements on two sides of the cutting surfaces, and the surface structure of the pervious concrete can be protected to ensure the road view.

Description

technical field [0001] The invention belongs to the technical field of concrete processing machinery, and in particular relates to a permeable concrete slitting device and a method for using the slitting device. Background technique [0002] Permeable concrete is a kind of porous lightweight concrete mixed with aggregate, cement, reinforcing agent, and water. Coarse aggregates are coated with a thin layer of cement paste to bond with each other to form a honeycomb structure with uniform distribution of pores. Therefore, the permeable concrete pavement can allow rainwater to flow into the ground, effectively replenish groundwater, alleviate some urban environmental problems such as the sharp drop in the city's groundwater level, and can effectively eliminate environmental pollution such as oil compounds on the ground, which is beneficial to the human living environment It is of great significance to the healthy development of urban rainwater management and water pollution pr...
