Problems solved by technology

[0004] Aiming at the deficiencies of the prior art, the present invention provides a quick cutting method for concrete structures, which solves the problem that the traditional single cutting method is used for cutting concrete, and the cutting edges of the concrete blocks will become rough when cutting with pure knives. It is not beautiful, and the cutting time is relatively long in the way of hydraulic cutting, which affects the overall cutting time and the production efficiency of the enterprise.

Embodiment 1

[0024] The joint cutting method of hydraulic cutting gun and knife cutting is adopted. The working pressure of the water jet for water pressure cutting is 30MPa, and the speed of the tool knife for knife cutting is 450S. While cutting with the knife, the external temperature needs to be controlled at 20°C. Its cutting method comprises the following steps:

[0025] S1. Cutting preparation work: According to the size of the concrete to be cut, prepare hydraulic cutting tracks, tool cutting tracks, tool cutting auxiliary cooling equipment and temperature control equipment corresponding to the length value, and prepare hydraulic cutting components and tool cutting components;

[0026] S2. Cutting installation work: firstly pave the tool cutting track prepared in step S1 on the upper side of the cutting concrete piece, and place the hydraulic cutting track prepared in step S1 on the upper side of the cutting concrete piece and at the cutting tool cutting After the upper side of the...

Abstract

The invention discloses a concrete structure rapid cutting method, and relates to the technical field of concrete cutting equipment. By adopting a combined cutting mode of a water pressure cutting gunand tool cutting, the working pressure value of a water jet cutter for water pressure cutting is 30-200MPa, the rotating speed of a tool cutter for tool cutting is 450-800S, the external temperatureneeds to be controlled to be 20-30 DEG C while the tool cutting is carried out, Components of tool cutting auxiliary cooling equipment comprise a nozzle, a water tank, a water pump, a connecting waterpipe and other related components, and the length value of a water pressure cutting rail and the length value of a tool cutting rail are larger than the length value of a concrete part. The problemsthat during traditional concrete cutting, a single cutting method is adopted, when pure tool cutting is adopted, cut edge strips of concrete blocks become coarse and the concrete blocks are not attractive in cutting, the cutting time is relatively long by adopting a water pressure cutting mode, the overall cutting time is influenced, and the production efficiency of enterprises is influenced are solved.

Description

technical field [0001] The invention relates to the technical field of concrete cutting equipment, in particular to a rapid cutting method for concrete structures. Background technique [0002] Concrete refers to the artificial stone made of cement as the main cementitious material, mixed with water, sand, stones, chemical admixtures and mineral admixtures when necessary, mixed in appropriate proportions, uniformly stirred, compacted and cured. Concrete is mainly divided into two stages and states: the plastic state before setting and hardening, that is, fresh concrete or concrete mixture; the hard state after hardening, that is, hardened concrete or concrete. The strength grade of concrete is divided by the standard value of cubic compressive strength. The strength grade of ordinary concrete in China is divided into 14 grades: C15, C20, C25, C30, C35, C40, C45, C50, C55, C60, C65, C70, C75 and C80 . [0003] The traditional concrete cutting adopts a single cutting method....
