Problems solved by technology

In order to reduce traffic accidents, various guardrails are installed on both sides of the road. The common guardrails are metal railings on the upper part of the concrete base or directly composed of iron railings on the metal bracket. The guardrails on the concrete base are used Concrete construction is required, which not only requires large-scale equipment for concrete pouring, but also requires maintenance after the construction of the guardrail before it can be used; while the construction of the guardrail directly composed of metal brackets and horizontal railings is simple, but the protective effect is not good. It is easy to deform and break when an accident occurs, and the maintenance cost is high; at the same time, both the concrete base guardrail and the metal bracket guardrail are hard structures without elasticity. When the car collides with the guardrail, the momentary impact load Under the action, the guardrail will basically not move, and the energy generated during the collision is basically absorbed by the vehicle itself, so the damage to the vehicle and the occupants in the vehicle will be great.
[0003] In addition, the existing fence construction process is carried out after setting out on site. The deployment of the fence during the construction process is basically based on experience and simple measurement with a ruler. protective effect

Embodiment Construction

[0035] The present invention will be described in detail below in conjunction with the accompanying drawings, so that those of ordinary skill in the art can implement it after referring to this specification.

[0036] Such as figure 1 and figure 2 As shown, an intelligent construction method for the suspended part of the crash barrier of the expressway, including:

[0037] The information of the expressway 1 to be installed with the anti-collision barrier is retrieved from the pre-stored high-definition map, and the information of the expressway 1 is analyzed by the analysis module to obtain the construction information of the anti-collision barrier.

[0038] After preparing materials according to the construction information of the anti-collision guardrail, carry the positioning module to the expressway 1, and carry out construction lofting on the expressway 1 according to the dispensing instructions of the positioning module, wherein the construction lofting is as follows:...

Abstract

The invention discloses an intelligent construction method for a suspension part for a crash barrier for an expressway. The intelligent construction method comprises the steps of analyzing informationof the expressway by combining a high-definition map and an analysis module to obtain construction information of the crash barrier; after materials are prepared according to the construction information, nailing anchor rods at all installation points on the expressway according to an implementation instruction of a positioning module; installing left side plates of the crash barrier on the anchor rods; using steel bars for connecting every two adjacent anchor rods; arranging transverse support steel bars on the two sides of the anchor rods; inserting bottom plates on right side plates of thecrash barrier, and installing the right side plates on the left side plates; arranging oblique support steel bars between the bottom plates and the transverse support steel bars; and filling the positions between the left side plates and the right side plates with rubber melting liquid, and installing top plates. The map and software analysis are combined to achieve accurate implementation of thecrash barrier, and the construction quality and the protection effect are effectively improved; and the crash barrier is simple in structure and convenient to construct; meanwhile, the structure is firm; and impact damage of accidents to vehicles and passengers is reduced.

Description

technical field [0001] The invention relates to the technical field of highway facility construction, in particular to an intelligent construction method for the suspended part of the anti-collision guardrail of an expressway. Background technique [0002] With the continuous development of economic construction, transportation is becoming increasingly busy. Traffic accidents are happening more and more frequently on highways or highway bridges. In order to reduce traffic accidents, various guardrails are installed on both sides of the road. The common guardrails are metal railings on the upper part of the concrete base or directly composed of iron railings on the metal bracket. The guardrails on the concrete base are used Concrete construction is required, which not only requires large-scale equipment for concrete pouring, but also requires maintenance after the construction of the guardrail before it can be used; while the construction of the guardrail directly composed o...
