Asphalt adhesive layer spreading device for annular-road curved surfaces and method

Abstract

The invention discloses an asphalt adhesive layer spreading device for annular-road curved surfaces and a method. The device comprises a spreading vehicle and an asphalt tank body arranged on the spreading vehicle; one side of the asphalt tank body is provided with a spreading device body for uniform spreading on the curved surfaces and a spreading adjustment device for adjusting a distance between the spreading device body and the curved surfaces, the spreading device body comprises a hose and a steel pipe which are communicated with the asphalt tank body, the axial outer side of the steel pipe is communicated with a circular pipe, the end, away from the asphalt tank body, of the hose is sealably communicated with the circular pipe, the axial outer side of the steel pipe is communicated with at least one nozzle corresponding to the curved surfaces in position, the hose is in sealed connection with the asphalt tank body, one end of the hose sleeves the outer circumference of the steelpipe and is in sealed connection with the steel pipe through a sealing sleeve, and the junction of the hose and the steel pipe is coated with an adhesive; the spreading distance between one end of thesteel pipe and the curved surfaces can be adjusted according to the spreading adjustment device, and uniform spreading on the curved surfaces different in curvature can be adapted to.

Description

technical field [0001] The invention relates to the technical field of asphalt spreading, in particular to a device and method for spreading an asphalt sticky layer on a curved surface of a ring road. Background technique [0002] Asphalt pavement is a pavement structure in which a certain thickness of asphalt mixture is paved on a flexible base or a semi-rigid base. Compared with gravel pavement, this kind of pavement has greatly improved driving comfort, safety and strength stability. Compared with cement concrete pavement, asphalt pavement has a smooth surface without joints, small driving vibration, low noise, and fast construction. Short construction period, fast open traffic, easy maintenance, suitable for phased construction of pavement, is an important structural form of pavement in our country. [0003] With the continuous vigorous development of my country's automobile industry, the proving ground, as a necessary facility for automobile research and development an...

Problems solved by technology

However, the traditional spreading vehicle not only cannot comprehensively spread the surface of the high-speed ring road, but also cannot effectively detect the spreading quality after spreading, which may easily cause the asphalt layer to be not fully and effectively adhered to each other.
