Working principle

1.Pressure effect: Through the action of a high-pressure pump, the equipment can generate powerful water jets up to 100 to 280 MPa, which are directly sprayed onto the surface of concrete. Concrete is a porous heterogeneous material with a three-phase porous structure at the microscopic level. When high-pressure water is sprayed onto the surface of concrete, over pressure is formed in the pores of the concrete. When this pressure exceeds the tensile limit of the concrete itself, the concrete will disintegrate and break.

2.Tension effect: High pressure water jet can generate tension inside concrete that exceeds the bending tensile strength of the material, causing cracks and gradual breakage of the concrete.

3.Non destructive principle of steel bars: Steel bars are homogeneous and solid materials, and water jets cannot penetrate their surfaces, so they will not be damaged during the process of crushing concrete.

Equipment composition

High pressure water pump: Provides power for water jets and generates high-pressure water flow, such as the GYB-6 model high-pressure water pump, diesel driven, with a maximum pressure of up to 2000 bar (29000 psi) and a flow rate of 105 lpm.

Execution mechanism: equipped with a rotatable and reciprocating hydraulic driven nozzle, such as GYB-6 Concrete Buster, which can be used for concrete dismantling, breaking, chiseling and other projects, and the operator can remotely control its operation.

Applicable scenarios

Road and Bridge Engineering: It can be used for the renovation, reinforcement, and maintenance of bridges, highway pavements, etc., such as removing degraded parts of bridge concrete and performing local repairs on highway pavements.

Construction Engineering: Suitable for the maintenance and renovation of buildings, such as removing damaged concrete from building walls, roughening the surface of concrete to facilitate the pouring of new concrete, etc.

Hydraulic engineering: In the maintenance of hydraulic concrete structures such as dams, ports, and docks, it can be used to remove damaged concrete and perform surface cleaning work.

Tunnel engineering: can be used for repairing and partially breaking the concrete lining of tunnels.

advantage

1.High precision: By adjusting pressure, flow rate, and number of strikes, the area, depth, and force of crushing can be precisely controlled within ± 3mm.

2.Strong applicability: It can be operated at any angle and height, and can easily achieve crushing construction in horizontal, vertical, top, and narrow spaces.

3.Good environmental performance: Using water as the working medium, it does not produce dust pollution and greatly reduces noise pollution. High safety: adopting mechanized and automated operation, supporting remote control from a distance, avoiding close contact of operators with hazardous environments.

4.Low impact on the original structure: There is no vibration during the entire construction process, which will not cause cracks in the surrounding concrete structure. The impact on the original structure and the components that need to be preserved is minimal, and the steel bars can also be fully preserved.

5.Good construction effect: The interface after breaking is clean and hard with concave and convex teeth, which is conducive to the tight adhesion between the old and new interfaces, without the need for additional chiseling treatment.
