Embodiment 1

[0057] For the above-mentioned construction method of partially reinforced embankment, familiarize yourself with the design documents before construction, and do a good job of on-site inspection. 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, lay the embankment 1, lay the filler and use local materials, which is environmentally friendly and economical. Include the following steps:

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

Embodiment 2

[0064] The above-mentioned rapid repair and reinforcement method for a locally reinforced embankment specifically includes the following steps:

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

[0066] Step b: backfill and compact the excavated side slope layer by layer, and reach a compaction degree that meets the specifications. After the compaction is completed, drill holes perpendicular to the slope of the embankment 1 until the slope Move below the surface;

[0067] Step c: pass the anchor rod 13 through the hole, and the circular top plate 9 end of the anchor rod 13 is placed at the end of the hole drilled in the step b located inside the embankment 1, the anchor rod 13 The center of the circular top plate 9 is provided wit...

Abstract

The present invention provides a method for quickly repairing and reinforcing a locally reinforced embankment. The locally reinforced embankment includes an embankment, and a first reinforcing unit is symmetrically arranged on the inside of the embankment towards the slopes on both sides of the embankment. The first reinforcing unit includes a second reinforcing unit. A geogrid, sandbags are stacked on the first geogrid, one end of the first geogrid is fixed in the middle of the embankment, and after it is straightened and tightened toward the road shoulder on one side, sandbags are piled on the road shoulder, and the other end of the first geogrid is The reverse-wrapped sandbags are fixed on the first geogrid closest to the sandbags. A second reinforcement unit is arranged inside the embankment close to the upper end of the embankment. The second reinforcement unit includes a second geogrid, and the second geogrid is laid in a connected manner. , the two ends of which are turned back with sandbags and fixed on the second geogrid closest to the sandbags. When carrying out reinforcement and repair, there is no need to excavate the whole section, so as to save economic investment and save time and cost, so as to optimize resources reasonably.

Description

Technical field: [0001] The invention belongs to the technical field of embankment reinforcement and maintenance in civil engineering, and in particular relates to a partially 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 has been done on embankment reinforcement technology at home and abroad, and fruitful results have been obtained. The embankment is the foundation of the track or road surface, which bears the static load and dynamic load of the track, motor vehicles or road traffic load, and transmits 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 tens...
