Construction method for transforming concrete pavement by using bituminous concrete

Abstract

The invention provides a construction method for transforming a concrete pavement by using a bituminous concrete. According to the construction method for transforming the concrete pavement by using the bituminous concrete, a construction device for transforming the concrete pavement by using the bituminous concrete can be utilized, wherein construction device for transforming the concrete pavement by using the bituminous concrete comprises a machine frame, a machine body, a guide wheel and a traveling wheel, wherein the machine body is arranged on the machine frame, the guide wheel is fixedlyconnected to the end, close to the advancing direction of the device, of the machine frame, the traveling wheel is arranged below the end, far away from the advancing direction of the device, of themachine frame, a controller is arranged in the machine body, a rotating shaft is fixedly connected to the machine body, the rotating shaft is fixedly connected with a saw blade through a connecting rod, a hand wheel is fixedly connected to the machine body, the hand wheel is connected with the rotating shaft through a transmission structure in the machine body, and the transmission structure is used for driving the saw blade to rotate around the rotating shaft when the hand wheel is rotated. According to the device, the hand wheel is connected with the rotating shaft, so that a worker can adjust the position of the saw blade relative to the rotating shaft by rotating the hand wheel so as to realize adjustment and control of the cutting depth of the saw blade.

Description

technical field [0001] The invention relates to the field of asphalt concrete reconstruction of cement pavement construction, in particular to a construction method for asphalt concrete reconstruction of cement pavement. Background technique [0002] In order to improve driving comfort and reduce noise and dust pollution, during road construction, the existing cement concrete pavement is generally changed from white to black, that is, after the original cement concrete pavement is treated with joint filling, emulsified asphalt is laid. , lay geotextiles, and then pave medium-grained asphalt concrete and thick fine-grained asphalt concrete surface. In the above steps, the treatment of expansion joints is an important part of the base treatment construction, and a slotting machine is needed to clean the gaps. The biggest disadvantage is that when cutting the road, it will be covered with a large amount of dust, which will endanger the operator. At present, some cutting machin...

In the above steps, the treatment of expansion joints is an important part of the base treatment construction, and a slotting machine is needed to clean the gaps. The biggest disadvantage is that when cutting the road, it will be covered with a large amount of dust, which will endanger the operator. At present, some cutting machines are equipped with water nozzles, but the effect is not very good, and it cannot effectively protect the safety of the operator. Sufficient depth, generally at least 8-10 cm. Since the strength, hardness, and stiffness of concrete pavement have a great relationship with the age of the pavement, the depth required for cutting pavements of different ages is also different. Personnel basically rely on their own feeling and experience to determine the depth of cutting, which makes the actual cutting depth different and affects subsequent construction
