Abstract
The invention belongs to the field of road maintenance, and provides a lateral-piling soil-squeezing grouting method for repairing settling roadbeds, and a precast pile in accordance with the problem that local grouting leak is easy to occur in road repair in the prior art. The lateral-piling soil-squeezing grouting method comprises the following steps: making piles: precasting steel pipe piles or reinforced concrete piles with a grouting channel and holes; laterally tamping the precast piles: laterally tamping the precast piles in a roadbed under a settling road surface; grouting through pressure: grouting solid concrete in the precast piles by utilizing hydraulic pressure or air pressure. Each precast pile comprises a hollow pile body, wherein through holes communicated with the hollow structure in the pile body are formed in the pile body; the front end of the pile body is shaped like a cone. According to the method disclosed by the invention, the soil squeezing effect of horizontal lateral tamping and the grouting reinforcement are effectively combined; the roadbed fillers are squeezed compactly through the lateral tamping close to horizontal tamping, so that the roadbed is squeezed high in the vertical direction, and the settlement deformation is resolved; the pressure grouting channel and the holes are reserved in the precast piles, so that the grouting reinforcement is more convenient and effective.
Description
Technical field
The invention belongs to road upkeep field, particularly relate to a kind of side direction piling soil compaction slip casting sedimentation roadbed restorative procedure and preformed pile.
Background technology
Due to the effect of the factors such as filler is uneven, filler is bad, filling compaction is insufficient, water content is too high, earthquake, Construction Vibration, vehicular load, penetration, deadweight, there is the Common Diseases that sedimentation and deformation is road foundation in road foundation.Subgrade settlement must cause the destruction of railroad track and highway pavement, endangers safe traffic.Therefore, the settlement issues of effective Subgrade, has realistic meaning for guarantee traffic safety.And the method for existing reparation roadbed is generally directly fill up sunk area at road surface depression place, this restorative procedure road surface running vehicle when reparation need detour, comparatively inconvenience, and repairing area needs must not drive a vehicle in certain hour, very inconvenient.At present, Some Domestic scholar has carried out research Roadbed Soil being improved to the aspects such as its intensity by grouting, although there is certain effect, because the degree of compaction of Roadbed Soil body is once more than 80%, grouting is just difficult to effectively carry out, and easily forms local and leaks irrigated area.
Summary of the invention
The object of the invention is to repair for existing road easily to form local and leak and fill with and a kind of side direction piling soil compaction slip casting sedimentation roadbed restorative procedure of providing and preformed pile.
The present invention is achieved by the following technical solution:
A kind of side direction piling soil compaction slip casting sedimentation roadbed restorative procedure, comprises the steps,
Step one, stake processed, the steel pipe pile of prefabricated band slip casting passage and hole or reinforced concrete pile;
Step 2, side direction is driven piles, and in the below roadbed having sedimentation road surface, preformed pile is squeezed in side;
Step 3, slip casing by pressure, utilizes hydraulic pressure or air pressure that the slurries that can solidify are injected preformed pile, by preformed pile, slurries is injected roadbed filling deck equably.
The preformed pile squeezed into described in step 2 is at least one.
A kind of preformed pile, comprises the body of hollow structure, body has the through hole be connected with the hollow structure in body.The leading section of body is pyramidal structure.
Beneficial effect of the present invention: horizontal side effectively combines to the soil compaction effect of driving piles and grouting and reinforcing by the present invention.By the compacted roadbed filling of piling of the nearly horizontal direction of side direction, roadbed in the vertical direction is squeezed high, recover sedimentation and deformation.By pre-reservation pressure grouting channel and hole in preformed pile, make grouting and reinforcing more convenient and effective.

Detailed description of the invention
Below in conjunction with embodiment, the invention will be further described.
Embodiment
As Figure 1-Figure 4, a kind of side direction piling soil compaction slip casting sedimentation roadbed restorative procedure, comprises the steps,
Step one, stake processed, the steel pipe pile of prefabricated band slip casting passage and hole or reinforced concrete pile;
Step 2, side direction is driven piles, and in the below roadbed having sedimentation road surface 2, preformed pile 1 is squeezed in side;
Step 3, slip casing by pressure, utilizes hydraulic pressure or air pressure that the slurries that can solidify are injected preformed pile 1, by preformed pile 1, slurries is injected roadbed filling deck equably.
The preformed pile squeezed into described in step 2 is at least one.
A kind of preformed pile, comprises the body of hollow structure, body has the through hole 11 be connected with the hollow structure in body.The leading section of body is pyramidal structure.
The present invention squeezes into the preformed pile close to horizontal direction by roadbed side, compacted roadbed filling, reduces space or hole that in roadbed, air and moisture content occupy, improves the compaction rate of roadbed.Preformed pile is squeezed in side direction horizontal direction, can squeeze elevated formation level filler at vertical direction, reaches the object recovering subgrade settlement, the design elevation before making road foundation height mark reach sedimentation.By grouting pipe reserved in preformed pile and hole, for pressure grouting provides passage.The effect of comprehensive side direction piling soil compaction effect and slip casing by pressure, realizes the reparation of sedimentation subgrade strength and distortion, ensures subgrade stability.
More than show and describe general principle of the present invention, principal character and advantage of the present invention.The technician of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and manual just illustrates principle of the present invention; without departing from the spirit and scope of the present invention, those ordinary skill in the art simple change and replace be all within protection scope of the present invention.
