Problems solved by technology

[0003] For the subgrade collapse, according to the degree and scale of the collapse and the site conditions, the method of filling soil to the outside or expanding the excavation to the side of the mountain is adopted. However, when the inner side is high and steep and the outer side is not easy to backfill, it will cause difficulties for the rapid clearance of the road.

Embodiment 1

[0040] Such as figure 1 Shown, a kind of bagged gravel sidewall construction method comprises the following steps:

[0041] S1. Preparation of bagged sand and gravel 3: use a small excavator or a shovel to fill the bag with filler, the filler is a mixture of soil, sand and gravel, wherein the particle size of the gravel is Less than or equal to 10cm, the distance between the collapsed gaps in the mining site of the filling is less than or equal to 5km, the volume of the filling in the said storage bag is 50-60%, and the filling in the storage bag should not be filled too full, filling After the completion, it is enough to fasten the mouth of the bag with a rope, and the storage bag is a straw bag, or a plastic woven bag or a sack;

[0042] S2. Use a forklift, loader or manually load the bagged soil into the dump truck, and transport the bagged sand and gravel 3 to the vicinity of the collapsed site by the dump truck;

[0043] S3, leveling the bottom of the collapsed gap, tra...

Embodiment 2

[0048] Such as figure 1 As shown, the present embodiment is based on embodiment 1, and the top of the anchor pile 1 described in step S5 is provided with a displacement monitoring system, and the displacement monitoring system includes a displacement module and a communication module for monitoring the displacement data of the anchor pile 1, and the displacement The module uploads the monitoring data to the terminal in real time through the communication module, and the terminal can be a computer.

[0049] The emergency headquarters can know the deformation situation in real time through the terminal. Once the deformation exceeds the critical value, it can call the police, and the emergency headquarters can immediately stop the traffic in this section to avoid safety accidents.

Embodiment 3

[0051] Such as figure 1 As shown, this embodiment is based on Embodiment 1, and also includes step S6:

[0052] Set warning signs and safety barrels on both sides of the collapsed gap section to avoid safety problems caused by passing vehicles rushing out of the road, and put reflective strips on the warning signs and safety barrels to facilitate night warning.

Abstract

The invention discloses a bagged gravel fence construction method. The bagged sand fence construction method comprises the following steps of S1, preparing bagged gravel, i.e., filling a bag with a filler, wherein the filler comprises at least one of soil, sand and gravel; S2, transporting the bagged gravel to a place close to a collapsed position; S3, leveling the bottom of a collapsed gap, transporting the bagged gravel to the collapsed gap, hierarchically stacking the bagged gravel on the slope toe of a collapsed slope line from bottom to top in a staggered way, and gradually leveling the slope; S4, when the bagged gravel is refilled to the original road side, paving one layer of cemented gravel pavement to obtain a new pavement; and S5, arranging a row of anchoring piles on the side, close to the bottom of the slope toe of an original roadbed slope line, of the bagged gravel. The construction method is suitable for first-aid repairing of a collapsed road segment which is high and steep in the inner side and is not liable to refill, and has the advantages of easiness and rapidness in construction.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a construction method for bagged sand and stone barriers. Background technique [0002] Road collapse is the most common disaster phenomenon. The most direct impact of road collapse is to affect traffic travel, and the indirect impact is to hinder the life channel of rescue. Therefore, when a disaster occurs, the first priority is to ensure smooth traffic to facilitate timely rescue, and how to quickly rush through the life channel is one of the most important things in emergency rescue and disaster relief. [0003] For the subgrade collapse, according to the degree and scale of the collapse and site conditions, the method of filling to the outside or expanding the excavation to the side of the mountain is adopted. However, when the inner side is high and steep and the outer side is not easy to backfill, it will cause difficulties for the rapid clearance of the road. ...
