Description

Technical Field

[0001] The invention relates to the technical field of embankment repair, in particular to a rapid repair structure and a construction method for a disaster-damaged embankment. Background Art

[0002] In my country, highway roadbed collapse accidents occur frequently, especially in the rainy season. Continuous rainfall in a short period of time causes a large amount of rainwater to accumulate. Due to poor drainage, some water directly seeps into the embankment, causing the filler and roadbed soil to soften. At the same time, the scouring and erosion of rainwater further reduce the roadbed strength and supporting capacity, thus causing roadbed collapse accidents.

[0003] In order to ensure the normal operation of highway traffic, the damaged embankment structure must be repaired quickly. Traditional repair methods mainly use retaining walls, roadbed backfilling and other methods, but there are problems such as long repair cycle, high project cost, and poor project applicability, which seriously affect the efficiency of post-disaster rescue. In addition, in order to increase the green area and reduce soil erosion, plants are generally planted on the repaired slopes. However, the plants need to be watered regularly after planting. When the sun is directly exposed, the plants are prone to lack of water and die easily without enough water. Therefore, the staff needs to water the plants regularly, which is very inconvenient and wastes time. Therefore, it is of great significance to study a new rapid repair structure and construction method for disaster-damaged embankments to solve the above problems. Summary of the invention

[0032] 2. The rapid repair structure and construction method of the damaged embankment, by adding a steel mesh to the repair section of the roadbed, laying steel pipe piles at the bottom of the roadbed for support, and connecting multiple steel pipe piles through precast concrete slabs to form a whole, and forming a grouting expansion head at the end of the steel pipe piles through grouting construction, not only reduces the on-site construction time and workload, shortens the repair cycle, but also improves the overall bearing capacity, anti-slip and anti-deformation capacity of the repair section of the embankment, reduces the occurrence of cracks and uneven settlement inside the embankment, and ensures construction efficiency and quality;

[0033] 3. The structure and construction method for rapid repair of the damaged embankment are as follows: a template is laid on the slope of the embankment of the repair section, and concrete is poured through the template to form a planting area and a drainage area, and one end of the side reinforcement component is poured in the planting area and the drainage area. The side reinforcement component is buried in the roadbed of the repair section, which can not only effectively improve the overall strength, but also connect the planting area and the drainage area, so that the planting area and the drainage area can be reinforced to prevent them from falling off, so that the drainage area and the planting area can form a protection for the slope of the embankment of the repair section, effectively preventing soil erosion and reducing the risk of slope instability. The drainage area can guide the discharge of road surface water to avoid the problem of soil erosion caused by accumulated water erosion again, and the accumulated water can flow back into the water tank to realize the problem of rational use of water resources. In addition, green plants are planted in the planting area, which can effectively reduce the damage caused by long-term rain erosion in the planting area;

[0034] 4. The structure and construction method for rapid repair of the damaged embankment can quickly absorb solar energy through the heat-absorbing layer, so that the sealed shell can gather heat and heat the internal gas. The gas expands due to the heat and puts pressure on the piston. The piston compresses the spring and presses out the accumulated water in the bottom cavity of the sealed shell, so that the liquid is output through the one-way water spray pipe and sprayed out through the water spray port to automatically water the green plants, which is convenient for the water replenishment of the green plants. When the temperature inside the sealed shell drops, the spring drives the piston to reset, so that the piston can introduce the accumulated water into the sealed shell through the one-way water inlet pipe, so as to facilitate the next water spraying operation.
