Example Embodiment

[0040] The following are specific embodiments of the present invention and combined with the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0041] like Figure 1-6As shown in the figure, a treatment process of a compound grouting pile for deep road diseases includes the following steps:

[0042] The first step is to use ground penetrating radar for detection, which can accurately grasp the type and location of road diseases, and then rationally customize the hole position plan according to the defects;

[0043] Step 2: Arrange and mark the hole positions. Use isosceles triangle pile arrangement, including hole A and hole B, and the diameter of hole A is larger than the diameter of hole B. The distance between hole A and hole A is 2m, and the row spacing is 2m. Select hole A. The hole diameter is 150mm, the distance between hole B and hole B is 2m, and the row spacing ...

Abstract

The invention provides a composite grouting pile treatment process for deep road diseases, and belongs to the technical field of road repair. The method comprises the following steps that 1, a ground penetrating radar is adopted for detection, the types and positions of highway diseases can be accurately mastered, and then a hole site scheme is reasonably customized according to defects; according to the grouting pile, holes are formed in a roadbed and a pavement to form the pile, the cement composite stable gravel material is poured to form a deep composite foundation, then inorganic silicon compound slurry is injected into the roadbed and a base layer through the grouting holes, moisture and air in cracks are discharged in a filling, permeating and compacting mode, the space of the cracks is occupied, and therefore the deep composite foundation is formed. The void ratio is reduced, the strength is improved, after a period of time, an original roadbed is cemented into a whole through chemical cementing, ion exchange, inert filling and compaction, a new composite supporting pile structure system is formed, and therefore the roadbed and a base layer are reinforced. The maintenance time can be 1-3 hours, and the traffic maintenance time is short.

Description

technical field [0001] The invention belongs to the technical field of road repair, and in particular relates to a treatment process for a compound grouting pile for deep road diseases. Background technique [0002] At present, asphalt concrete pavement and cement concrete pavement are the most important pavement forms in my country. However, with the increase of vehicle load, the damage of overweight vehicles to the road surface is increasing, and the roads built in the early stage enter the maintenance stage in advance. Among many pavement diseases, subgrade disease is the root cause of pavement disease, and it is also the most difficult disease to eradicate. Most of the cracking, subsidence, network cracking, cracking and other diseases of the pavement are caused by deep-seated diseases such as roadbed voiding and settlement. The deep-seated diseases of the road cause great harm to the pavement structure. It can reduce maintenance costs, extend the operating life of roa...
