Composite highway anti-collision pier, parking lot anti-collision facilities, highway isolation anti-collision facilities

  With the increasing number of vehicles, the traffic accidents caused by the collision between cars and piers or guardrails occur frequently, resulting in vehicle damage and death and pier collapse
The effect of common anti-collision facilities, such as warning, rigid isolation and other simple anti-collision facilities, is not good
Flexible composite highway pier anti-collision facility is a new type of protective facility attached to the pier or guardrail
The composite shell provides high-strength overall support, and the interior is filled with high-energy consumption closed hole materials to provide a stable crushing deformation mechanism
The crushing, extrusion and friction of composite materials are used to achieve the ideal energy consumption effect, so as to protect personnel, vehicles Safety of piers or highway facilities to reduce losses

Design concept of highway pier anti-collision facilities:
With & ldquo; Overcome hardness with softness, avoid reality and absorb gradually & rdquo; As the design concept, take & ldquo; Safety of people, bridges and Vehicles & rdquo; For the design idea, give full play to the characteristics of high toughness and aging resistance of the composite, fill with high-performance closed cell energy absorbing materials, and gradually absorb the impact force at the moment of impact by using the crushing, extrusion and friction of the composite

The flexible composite highway pier anti-collision facilities produced by Hengshui shengte Technology Co
, Ltd
are divided into Expressway pier anti-collision facilities and interchange pier anti-collision facilities

Brief introduction of anti-collision facilities for Expressway piers
Expressway pier anti-collision facilities, also known as expressway pier attached flexible anti-collision device, is a kind of flexible composite bridge pier anti-collision facilities attached to the middle or around the piers on both sides of the expressway

The anti-collision facilities are assembled with composite material unit modules
The anti-collision facilities suitable for use are formulated according to the vehicle traffic conditions (vehicle grade, speed limit grade) and pier size

Anti collision design concept of anti-collision facilities for Expressway piers
With & ldquo; Overcome hardness with softness, avoid reality and absorb gradually & rdquo; As the design concept, take & ldquo; Safety of people, vehicles and bridges & rdquo; For the design idea, give full play to the characteristics of high toughness and aging resistance of the composite, and use the high-performance closed cell energy absorbing material of stripworm to gradually absorb the impact force at the moment of impact by using the crushing, extrusion and friction of the composite

Classification of highway pier anti-collision facilities
According to the assembly form, the anti-collision facilities of Expressway piers can be divided into block combined unit module and box module

Block combined unit module: each unit is fixed on the pier through the connecting device, and the height can be adjusted according to the situation of passing vehicles
The installation and disassembly are convenient, and the maintenance and replacement operation is simple

Box type module: increase and strengthen the head-on, and the high-performance closed hole energy absorbing material in the box can absorb greater impact force, which is suitable for the protection of large vehicle passing areas

According to the traffic conditions, pier size and other on-site installation conditions, the anti-collision facilities of Expressway piers can be divided into: Circular Pier attached anti-collision device, elliptical pier attached anti-collision device, rectangular pier attached anti-collision device, semicircular pier attached anti-collision device, thin-walled pier guide block anti-collision device, etc

  Characteristics of anti-collision facilities for highway piers
1
The appearance is eye-catching, with night reflection function, which can give early warning and warn passing vehicles

2
It is a three-stage buffer energy absorption
Absorb the impact kinetic energy through step-by-step deformation and pressure feed to protect the safety of piers, vehicles and personnel

3
The three-level energy absorption area works together and is in the form of unit module, which can play the following roles: small collision can not be repaired, medium collision can be repaired, and large collision can be replaced

4
Installation and replacement do not require any mechanical equipment, which can minimize the occupation of vehicle traffic area and reduce the risk of installation personnel

5
Multi stage energy absorption, step-by-step buffering, and the attached anti-collision device has the characteristics of high toughness and high energy absorption, which can realize & ldquo; Small collision is not bad, medium collision can be repaired, large collision is easy to replace & rdquo;

6
It has beautiful appearance, aging resistance and corrosion resistance
It can be used normally without being impacted by external forces, and its service life is more than 30 years

Success stories:
1、  Jinzhou Jizhou Expressway starts from near xuzhuangzi, the intersection of Jinzhong road and outer ring road, connects Jinzhong Road, and ends at 3km west of Jizhou District, connecting Bangxi highway
