s7: grouting, namely placing the connecting pipe 6 into a grout storage tank 7, then starting the grouting pump 5, and starting grouting into the drill hole 3 by using the grouting pipe 9;
s8: and sealing, namely when the grouting construction is finished and the grouting pipe 9 is removed after the grouting slurry is stable, and then sealing the grouting hole by using broken stone concrete.
Specifically, in the process of reinforcing the roadbed 2, a grouting technical scheme is compiled according to the engineering general outline, and grouting technical parameters are determined, wherein the grouting technical parameters comprise grouting hole depth, grouting hole distance, grout proportion, grouting pressure, grouting sequence and the like; arranging holes, namely drawing a grouting hole location plane arrangement diagram in a grouting area of the roadbed 2, numbering each hole location, and calculating the hole depth of each grouting hole according to design requirements; drilling a hole 3, wherein the construction of the hole 3 is to reach the designed depth position, and then slowly pulling out the drill rod; installing a grouting pipe 9, inserting the grouting pipe 9 into the drill hole 3, and slowly inserting the grouting pipe 9 along the direction of the drill hole 3 in the inserting process to avoid unnecessary disturbance to the hole wall; hole sealing, wherein hole sealing treatment needs to be carried out in time after the grouting pipe 9 is installed, so that grouting is prevented from being upwards released in the grouting construction process; preparing the slurry, and preparing the slurry according to the requirement of the designed proportion. According to the requirement, the stirring time of the slurry is controlled to be 1.5 min-2.5 min. After the slurry is stirred uniformly, it needs to be injected into the slurry storage tank 7. It should be noted that the slurry should pass through the first filter 24 and the second filter 25 to remove large particles of impurities; grouting, the slurry suction pipe is first put into the slurry storage tank 7, and then the grouting pump 5 is started to start grouting. In the grouting construction process, the slurry can be subjected to layered grouting (the grouting amount is controllable) according to the property of soil, and the grouting pressure is slowly increased; and the stirring assembly 10 is utilized to continuously stir the grout in the grout storage pipe, so as to ensure the uniformity of the grout and observe the conditions of grouting pressure, grout inlet amount and the like. If the slurry is blocked, stopping grouting construction immediately, cleaning the pipeline, and then continuing grouting construction; and (4) sealing, wherein after grouting construction is finished, the grouting pipe 9 cannot be immediately removed, and the pipeline can be removed after grouting slurry is stable after the pipeline needs to be placed for a period of time. After the grouting pipe 9 is removed, the grouting hole needs to be sealed by adopting broken stone concrete.
The roadbed 2 is sequentially grouted and reinforced, so that the strength, compressibility, impermeability and stability of the roadbed 2 are improved, the problem of jumping and vehicle jumping is effectively solved, the settlement between the abutment and the original roadbed 2 is reduced to a great extent, and the service life of the road is prolonged.
While the invention has been described with reference to a preferred embodiment, it will be understood by those skilled in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the invention as defined by the appended claims.
