Abstract

Disclosed is a double-stage spraying roadbed material maintenance device. One end of a water inlet pipe is connected with a water source. The other end of the water inlet pipe is connected with a high-pressure water pump. A waterway passing the high-pressure water pump is connected with a rubber pipe. The rubber pipe is connected with a grading water pipe fixed to a rotary shaft. The bottoms of two sets of hydraulic jacks are fixed to a rack. The extending ends of the hydraulic jacks are connected with the bottoms of sliding plates correspondingly. An output shaft of a driving motor is connected with the rotary shaft through a speed reducer. The other end of the rotary shaft is connected with the middles of the sliding plates through bearings. The grading water pipe is provided with a first stage spraying head and a second stage spraying head. According to the double-stage spraying roadbed material maintenance device, the grading water pipe, the first stage spraying head and the second stage spraying head are used for distributing pumped-in high-pressure water flow in a shunted mode, the distributing range is larger, the distributed water quantity is larger, and thus the maintenance level of roadbed materials can be promoted effectively.

Description

technical field [0001] The invention is a two-stage spraying roadbed material maintenance device, which belongs to the technical field of road base material maintenance application. Background technique [0002] The pavement base is divided into inorganic binder stable base and crushed and gravel base. Play the role of stabilizing the road surface. The pavement base layer is a layered structure paved with a single material on the surface of the roadbed (or cushion) according to certain technical measures. The quality of its material and quality directly affects the quality and performance of the pavement. Inorganic binder stabilized base is a semi-rigid base, commonly used are lime (cement) stabilized soil, lime (cement) stabilized aggregates, lime fly ash stabilized soil or stabilized aggregates. Among them, the fly ash stabilized pellets can be used for high-grade pavement base or subbase. [0003] Inorganic binder stabilized base is a semi-rigid base, commonly used are...
