highway guardrail nc construction

highway guardrail nc construction intends to adopt key breakthrough procedures, parallel operation method construction, drainage pipeline, road construction is the key procedures of this project, other work must first ensure the smooth progress of these two work.

In the overall construction, reasonable flow construction is carried out, the labor force arrangement is relatively balanced in all stages of construction, the work of each shift is clear, and the overlap is tight. Under the premise of guaranteeing the quality and time limit, the cost is optimized.

The sequence of highway guardrail nc construction is as follows: earthwork excavation construction drainage pipeline construction subgrade construction Graded Macadam Subbase Construction cement stabilized rock debris layer construction cement concrete pavement construction greening, lighting, traffic facilities construction.

Subgrade excavation is mainly carried out by sectional longitudinal excavation, supplemented by stratified longitudinal excavation, excavator excavation and loading, dump truck transportation. The contract section can be operated by bulldozing earthwork, remotely using earthwork excavator digging and loading, dump truck transportation.

Subgrade filling is divided into sections, excavator or loader loading, dump truck loading, bulldozer paving, grader leveling, push roller rolling, nuclear densimeter method to test compactness.

Adopt stabilized soil mixing station mixing, dump truck transportation, leveler leveling, 15T roller initial pressure, vibratory roller compaction.

Concrete mixing station mixing, concrete truck transportation, manual paving, insert vibrator, plate vibrator, vibrating beam vibrating, using vacuum water absorption technology, mechanical polishing, mechanical engraving, slotting.

It has the advantages of lightweight, novel shape, beautiful and durable, as a professional railroad guardrail products on both sides have different coverage and effect.

Application of highway guardrail

Application of highway guardrail

1, the railway fence should also use the bridge suitable for domestic expressway as an anti throwing net.

2, all use high efficiency dipping. Ten years warranty against rust. Setting Principles Guardrail Analysis Editorial Material Guardrail commonly used steel products, such as: stainless steel, round steel, square steel or profiled steel, wire. Surface treatment process: full automatic electrostatic powder spraying (i.e. spray molding) or spray painting. In recent years, there are more popular aluminum alloy inserting and assembled guardrail.

Road guardrail is now an indispensable part of the highway. It has many outstanding characteristics.

The road guardrail is an assembly design without soldering. The installation is fast and simple.

The four-layer anti-corrosion treatment of the road guardrail solves the problem of rusting and breaking of the traditional products in a short time and eliminates the cost of maintenance and renewal.

Road guardrail has good decoration and rich colors, which can meet the individual needs of different customers.

The road guardrail is environmentally friendly and does not pollute the environment. It solves the problem of common products polluting buildings. Good toughness is a good barrier performance of road guardrail.

Guardrails are made of steel, such as stainless steel, round steel tube, square steel tube or profiled steel sheet, iron wire. Surface treatment process: full automatic electrostatic powder spraying (i.e. spray molding) or spray painting. In recent years, aluminum alloy material is also popular in the form of plug-in and assembled guardrail.

The column of the guardrail is fixed to the ground through expansion bolts. Usually installed on both sides of the logistics channel, production equipment around the corner of the building, both sides of the door and the edge of the platform and so on.Effectively reduce the damage of equipment and facilities caused by accidental impact when handling equipment.

Bridge fence bridge fence bridge fence can effectively prevent out-of-control vehicles out of the bridge under longitudinal pressure components. According to the magnitude of the impact load, it can be divided into main longitudinal effective members (such as main beams) and secondary longitudinal effective members (such as secondary beams).
