Embodiment 1

[0057] For the construction method of the above-mentioned partially reinforced embankment, be familiar with the design documents before construction and do a good job of on-site verification. According to the survey data and design documents, make a timely organizational design, including construction methods, resource allocation, etc., and then carry out basic engineering construction and component production. According to the design and specification requirements, pave the embankment 1, pave the filler and use local materials, environmental protection, economy, and specific It includes the following steps:

[0058] Step A: The roadbed site is processed, leveled and compacted to meet the design and specification requirements. The embankment 1 is laid with filler, and the filler is laid according to the actual position of the construction line during the laying process, and the filler is layered and compacted. When the filler is laid, a certain thickness of expansive soil filler ...

Embodiment 2

[0064] The above-mentioned method for rapid repair and reinforcement of partially reinforced embankments specifically includes the following steps:

[0065] Step a: Determine the damaged location of the embankment 1. According to the damage of the embankment 1, excavate the slope where the sliding damage occurs under the first reinforcement unit 2 at the damaged location, and the depth of excavation should reach slip. The location of the face;

[0066] Step b: Backfill and compact the excavated side slope layer by layer, and achieve a compactness that meets the specifications. After compaction is completed, drill holes perpendicular to the slope of the embankment 1 until the slide is drilled. Below shift

[0067] Step c: Pass the anchor rod 13 through the hole, and place the end of the round top plate 9 of the anchor rod 13 at the end of the hole drilled in the step b located inside the embankment 1, and the anchor rod 13 A first connecting hole 10 is opened at the center of the ci...

Abstract

The invention provides a locally reinforced embankment, a construction method and a quick repairing and reinforcing method thereof. The invention discloses a local reinforced embankment. Embankment isincluded, first reinforcement units are symmetrically arranged on the slope faces, facing the two sides of the embankment, in the embankment. The first reinforced unit comprises a first geogrid; sandbags are piled on the first geogrid; one end of the first geogrid is fixed in the middle of the embankment, straightened and tightened towards the direction of the road shoulder on one side, and thensandbags are stacked on the road shoulder part, the other end of the first geogrid reversely wraps the sandbags and is fixed to the first geogrid closest to the sandbags; a second reinforcement unit is arranged at the position, close to the upper end face of the embankment, in the embankment and comprises a second geogrid, the second geogrid is laid in a communicated mode, and two ends of the second geogrid reversely wrap the sandbags and are fixed to the second geogrid closest to the sandbags. And during reinforcement and repair, excavation treatment does not need to be conducted on the wholesection, so that economic investment and time cost are saved, and resources are reasonably optimized.

Description

Technical field: [0001] The invention belongs to the technical field of embankment reinforcement and maintenance in civil engineering, and specifically relates to a locally reinforced embankment, a construction method and a quick repair and reinforcement method thereof. Background technique: [0002] With the rapid development of social economy, in order to meet the increasing social needs, higher requirements are put forward for the development of transportation. In recent years, a lot of research on embankment reinforcement technology has been carried out at home and abroad, and fruitful results have been obtained. The embankment is the foundation of the track or pavement. It bears the static and dynamic loads of the track and the traffic load of motor vehicles or the road, and transfers and spreads the load to the depth of the foundation. It must be stable and strong to ensure the good condition of the line. As a natural geological material, soil has very low or almost no te...
