Embodiment 1

[0048] like 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 14-1...

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 realizing rapid water drainage and gas exhaust of a rubber soil roadbed comprises a double-rolling-wheel type road roller vehicle body; a fixing bracket is mounted in front of thedouble-rolling-wheel type road roller vehicle body; a front rolling wheel and a rear rolling wheel are mounted in the fixing bracket; lifting rods with slide blocks are fixed on the two sides of thefront end surface of the fixing bracket; a microwave heating device is mounted on the front end surface of the fixing bracket through a slide block; the front rolling wheel is a tamping roller and comprises an external roller; the external roller is an embedded steel pipe structure which is formed by combining an internal cylinder steel plate and an external cylinder steel plate; a supporting layer is arranged between the internal cylinder steel plate and the external cylinder steel plate; the supporting layer consists of multiple arc plate bodies which are spliced with each other; and mounting grooves with semicircular sections are formed in the two side surfaces of the arc plate bodies. According to the rolling device and method for realizing rapid water drainage and gas exhaust of the rubber soil roadbed, problems that the construction efficiency is low and effective action on rubber soil in the deep layer cannot be generated can be solved, and water and gas in the deep layer of therubber soil roadbed are rapidly and efficiently drained and exhausted.

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...
