Problems solved by technology

However, the currently commonly used temporary guardrail structure is relatively simple. During its assembly process, the connection between two adjacent guardrails is not strong enough. Once a traffic accident occurs, the possibility of breaking the guardrail is very high, causing serious harm to the construction line and accident vehicles.
In addition, the current temporary guardrail structure lacks relevant signal warning signs, and the sight range is reduced during night driving on the expressway, which greatly increases the probability of traffic accidents

Embodiment 1

[0030] A highway guardrail with intelligent dust suppression and road surface maintenance functions, refer to figure 1 ,include:

[0031] Guardrail body 5, guardrail body 5 is provided with connecting plate 7 along the first end of length direction, and the second end is provided with connecting socket 13, and connecting plate 7 is inserted in the connecting socket 13 on the guardrail body of another expressway guardrail, with Realize the connection between highway guardrails; the bottom of the guardrail body 5 has a card slot 6 connected to the ground;

[0032] The sprinkler dust suppression and maintenance unit, the sprinkler dust suppression and maintenance unit includes at least one water pipe 1 arranged on the guardrail body 5, a plurality of nozzles 2 are arranged on the water pipe 1, and the spraying direction of the nozzles 2 points to the construction road surface; The water pipe 1 is connected with the water pipe 1 on the guardrail body 5 of another expressway guard...

Embodiment 2

[0044] An installation method of an expressway guardrail with intelligent dust suppression and road surface maintenance functions, using the expressway guardrail with intelligent dust suppression and road surface maintenance functions provided by embodiment 1, the installation method includes the following steps:

[0045] S10. Fix the first expressway guardrail to the ground through the slot 6 at the bottom of the guardrail body 5 at an appropriate position.

[0046] S20, install the second expressway guardrail, insert the connection plate 7 of the first expressway guardrail into the connection socket 13 of the second expressway guardrail, and connect; in the connection between the first expressway guardrail and the second expressway guardrail During the process, it should be ensured that the first expressway guardrail is aligned with each part of the second expressway guardrail;

[0047] S30. Fixedly connecting the guardrail of the second expressway with the ground;

[0048]...

Embodiment 3

[0054] During the reconstruction and expansion of a highway, the existing highway and the highway under construction were only separated by ordinary steel guardrails, and no other protection measures were taken. There are many risks in such a partition. First, a large amount of dust will be generated during the construction of the line, which will affect the safety of driving on the existing line. Second, the connection between the ordinary steel guardrails is not strong enough. When an accident occurs, the ordinary steel guardrails will not be effective. In addition, there is no warning device in the process of driving at night, so there is a great potential risk.

[0055] This embodiment can be applied to the reconstruction and expansion construction of this expressway. First, install the expressway guardrail (temporary guardrail) one by one, and make it reliably connected with the ground, then connect the power supply and water source, turn on the sprinkling dust suppression...

Abstract

The invention discloses an expressway guardrail with intelligent dust suppression and pavement maintenance functions and an installation method, and belongs to the technical field of highway bridge engineering. The expressway guardrail comprises a guardrail body, a connecting plate is arranged at the first end of the guardrail body in the length direction, and a connecting socket is formed in the second end of the guardrail body; the connecting plate is inserted into a connecting socket on a guardrail body of another expressway guardrail so as to realize the connection between the expressway guardrails; a clamping groove connected with the ground is formed in the bottom of the guardrail body; a water sprinkling dust suppression and maintenance unit is adopted, and comprises at least one water pipe arranged on the guardrail body, a plurality of spray heads are arranged on the water pipe, and the water spraying direction of the spray heads points to a construction road surface; and the water pipe on the guardrail body is connected with the water pipe on the guardrail body of another expressway guardrail through a joint. The expressway guardrail is suitable for solving the problems of running vehicle driving sight, safe driving and atmospheric environment caused by dust on the two sides in the highway splicing and widening construction process.

Description

technical field [0001] The invention belongs to the technical field of highway and bridge engineering, and in particular relates to an assembled enhanced highway guardrail with intelligent dust suppression and road surface maintenance functions and an installation method. Background technique [0002] In recent years, with the continuous development of my country's social economy, although my country's investment in infrastructure construction has increased year by year, some existing expressway networks have gradually become saturated, and expressway congestion is common, seriously affecting the passage of expressways capacity and service levels. Therefore, in order to maintain a good and stable traffic order in our country, some existing highways must be reconstructed and expanded. The widening construction is to widen the existing expressway and increase the number of lanes, thereby alleviating the traffic pressure on the existing expressway. [0003] During the widening...
