Embodiment Construction
[0017] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.
[0018] A complete set of equipment for crushing road and bridge pavement by high-pressure reciprocating abrasive jet,
[0019] Such as figure 1 As shown, the complete set of equipment includes three parts: high-pressure pump truck 1, water truck 2 and work truck 3. High-pressure hoses are connected in 4 phases.
[0020] Such as figure 2 , image 3 As shown, the main body of the work vehicle is a miniature vehicle equipped with an abrasive box. The front end of the miniature vehicle is connected to a swingable base plate 13 through a cylinder 14. A guide rail 6 and a rack 11 are arranged on the outer end surface of the base plate 13. A fixed plate 2 is installed on the guide rail 6 to fix the The motor 1 and the nozzle body 3 are fixed on th...

A process and complete equipment for smashing road and bridge pavements via high-pressure reciprocating abrasive material jet relate to the technical field of road and bridge pavement smashing. Pure water jet is jet into the abrasive materials to form abrasive material jet, and supersonic-speed abrasive material jets are utilized to smash the road and bridge pavements in reciprocating mode. The complete equipment for smashing the road and bridge pavements via the high-pressure reciprocating abrasive material jets comprises three parts including a high-pressure pump truck, a water vehicle and an operating vehicle, wherein the high-pressure pump truck is connected with the operating vehicle via a high-pressure hose. By the aid of the process and the complete equipment for smashing the road and bridge pavements via the high-pressure reciprocating abrasive material jets, a full-thickness smashing of concrete pavement of a conventional process is changed into selectable layered smashing, thus project quantity and working noise are greatly reduced, meanwhile, working efficiency is greatly improved by advancing 4 meters in length and 1.5 meters in width per minute, and waste output is reduced.
Description
Technical field: [0001] The invention relates to the technical field of road and bridge pavement crushing, in particular to a process and a complete set of equipment for crushing road and bridge pavement by a high-pressure reciprocating abrasive jet. Background technique: [0002] The concrete pavement of road and bridge maintenance is currently broken by hydraulic vibration brazing technology. Its characteristic is that due to the stress propagation of frequent brazing, the crushing method must be extended from the upper surface to the lower surface. When the thickness reaches more than 400mm, the concrete or asphalt pavement is completely broken into large stones and becomes a waste product. The construction work is huge, and there is no choice for the pavement. Invention content: [0003] The purpose of the present invention is to realize the crushing and destruction of the surface layer of concrete or asphalt pavement, that is, only the oxide layer, cracked layer, and...
