Embodiment 1

[0048] Such as Figure 1-Figure 10 As shown, a rolling device for realizing rapid drainage and exhaust of rubber soil roadbed includes a double-roller roller body 8, a fixed bracket 3 is installed in front of the double-roller roller body 8, and a front Rolling roller 13 and back rolling roller 12,

[0049] Lifting rods 9 with sliders 2 are respectively fixed on both sides of the front end of the fixed bracket 3, and the microwave heating device 1 is installed on the front end of the fixed bracket 3 through the slider 2;

[0050] The front rolling roller 13 is a sheep foot roller, including an outer cylinder 20, the outer cylinder 20 is an embedded steel pipe structure composed of an inner cylinder steel plate and an outer cylinder steel plate, and a supporting layer 14 is arranged between the inner cylinder steel plate and the outer cylinder steel plate The support layer 14 is composed of multiple arc-shaped plates 14-1 spliced ​​together, each side of the arc-shaped plate 1...

Embodiment 2

[0061] A method for the above-mentioned rolling device to realize rapid drainage and exhaust of rubber soil roadbed, the method comprises the following steps:

[0062] Step 1: During the rolling process, the distance sensor 4 and the humidity sensor 17 at the front end of the fixed bracket 3 sense the humidity of the soil and the height of the microwave heating device 1 respectively, adjust the power of the microwave heating device 1 and start the lifting rod 9 according to the data Adjust the height of the microwave heating device 1 so that the microwave heating device 1 rapidly heats the soil body in front of and below the rolling roller 13;

[0063] Step 2: The bumps 21 on the front rolling roller 13 penetrate into the soil, and with the vibration of the vibrating device 5, the sheep's feet gradually penetrate into the soil and loosen the soil;

[0064] Step 3: Open the suction device 7 to pump out the gas, and the water vapor in the soil is quickly discharged through the a...

Abstract

A rolling device for rapid drainage and exhaust of rubber soil roadbeds, comprising a double-roller road roller body, a fixed bracket is installed in front of the double-roller type road roller body, and front rolling rollers and rear rolling rollers are installed in the fixed bracket Rollers, lifting rods with sliders are fixed on both sides of the front end of the fixed bracket, and the microwave heating device is installed on the front end of the fixed bracket through the sliders; The embedded steel pipe structure is composed of the inner steel plate and the outer steel plate. There is a support layer between the inner steel plate and the outer steel plate; the support layer is composed of multiple arc-shaped plates. A semicircular mounting groove is provided in section. The rolling device and method provided by the present invention to realize rapid drainage and exhaust of rubber soil roadbed can solve the problems of low construction efficiency and inability to effectively act on deep rubber soil, and quickly and efficiently drain the water in the deep layer of rubber soil roadbed. , Gas discharge.

Description

technical field [0001] The invention relates to the technical field of road surface construction, in particular to a rolling compaction device and method for realizing rapid drainage and exhaust of rubber soil roadbed. Background technique [0002] Rubber soil refers to cohesive soil that cannot be compacted because the water content of the soil is higher than that required to achieve the specified degree of compaction. From the perspective of engineering construction, rubber soil is likely to cause uneven settlement of the foundation and affect the safety of the ground building structure, so it cannot be used as roadbed soil and needs to be treated before construction. [0003] The current methods of processing rubber soil are as follows: [0004] 1. The smooth surface is rolled repeatedly or tamped with a heavy hammer. [0005] 2. When the construction period allows, carry out a long period of natural drying. [0006] 3. Excavate and replace. [0007] 4. Add a large am...
