Technical Field

The invention relates to highway construction safety facility equipment, in particular to a construction baffle and vehicle warning structure of a narrow-distance separation belt and a using method of the construction baffle and the vehicle warning structure.

Background

In order to ensure the driving safety and the functions of the expressway and the first-level highway, an intermediate belt is arranged. The function of the device is to separate the back-and-forth traffic flow so as to avoid traffic accidents caused by rapid vehicles driving into opposite traffic lanes; the accident caused by mistakenly recognizing the opposite lane of the vehicle on the undivided multi-lane highway can be effectively prevented, and the traffic resistance near the center line is reduced. According to the design tradition and related requirements of the central division zone in China, when the middle zone has a certain width, tree planting or anti-glare facilities are required.

However, in addition to the standardized design of the central dividing strip in the expressway and the first-level highway, the width of the central dividing strip is extremely limited, and is only 0.8-1.2m, during the construction process of the highway due to the construction age, land planning, red line construction and the like of some main roads in the places such as political and economic centers, large industrial and mining areas and the like, or suburban roads with busy transportation. In the repair engineering of rain and sewage pipelines in municipal engineering in a certain prefecture city in 2021, pipelines buried under a central dividing belt need to be excavated and repaired, the width of the central dividing belt of a road section is designed to be gradually reduced from the middle of the road section to an intersection, the construction allowable width provided by the narrowest part of the intersection is only 0.5m, a lane close to one side or two sides of the central dividing belt needs to be occupied for normal construction, and a plurality of temporary construction guardrail structures and guide boards are arranged for warning and inducing passing vehicles.

The existing guardrail structure mainly uses temporary foundation pit fences and edge-facing protection, but in actual use, the adaptability of the guardrail to a narrow central separation zone of the width is obviously insufficient, and the safety guardrail has less demand under the condition of unevenness and narrow distance, so that a mature product related to the demand is not found in the market. The deficiency is as follows: (1) under the uneven narrow-distance condition, the existing guardrail base lacks the support stability, resulting in the safety being insufficient. The reason is that the two types of guardrails need to be laterally arranged on a road surface with high flatness, if a curb stone or other barriers with the height of 15-20cm are crossed, the temporary foundation pit fence and a base on one side facing the edge protection are suspended with high probability, so that the support is unstable, in some cases, in order to ensure the stability of the support legs, constructors can obliquely place and laterally place the temporary foundation pit fence and the base facing the edge protection and fix the temporary foundation pit fence and the base facing the edge protection by sand bags, stones or other heavy objects, although the method can increase the stability of the guardrail structure to a certain extent, the heavy objects such as the sand bags and the stones used at the same time can indirectly increase the floor area of the guardrail structure. In the separation zone under the narrow-distance condition, sand bags and stones are used as road surface foreign matters to seriously threaten the driving safety. (2) The safety is insufficient because the vehicle is easy to overturn and fall to the ground under the condition of strong wind. In the environment of poor lighting conditions and rain and snow, once a vehicle collides with the vehicle, personnel and the vehicle are damaged, the conventional safety guardrail structure is made of metal materials, and belongs to a rigid structure, and particularly when the vehicle runs at an excessively high speed, the driver still has the risk of deviating from the original lane due to improper operation, such as secondary damage caused by impact on a separation belt or scratch of the vehicle on an adjacent lane. In this type of road section, if the installation and maintenance engineering of the power line is performed, the street lamp of the road section is inevitably closed and the driving view is poor, and the driving risk is further increased. (3) In actual use, the main functions of the device are shielding and isolating, and the warning and inducing performances are not strong. When a vehicle passes through the temporary foundation pit fence and the temporary edge protection fence, the driver can obtain a turning or decelerating visual signal at the safe driving distance of the lane obstacle under the ideal condition, but the arrangement directions of the temporary foundation pit fence and the temporary foundation pit edge protection fence are mostly in weak included angles with the driving direction, so that the driving behavior conversion is started when the driver approaches the obstacle, and the reaction time is greatly shortened compared with the conventional method.

Taking the foundation pit fence selected in the construction of a certain road as an example, the defects about the deficiency and harm in (1), (2) and (3) are shown, the foundation pit fence is limited by the width (the width is about 1.8m, and the narrow part is about 0.5 m) of a central separation band, a temporary guardrail structure is close to a curb stone, but still occupies about 1/3 of the width of an inner lane, and due to the overturning of the fence caused by strong wind weather and other factors, vehicles running at high speed come and go collide with the foundation pit fence; in addition, rear-end accidents occur because the front car can timely find that the rail in the road is blocked and then decelerates, and the rear car can cause the rear-end accidents with the front car due to the fact that the front car brakes suddenly and the vision blocking and the night sight conditions of the road section are poor.

Therefore, it is necessary to provide a narrow-distance partition strip construction barrier, a vehicle warning structure and a use method for a narrow-width central partition strip, so as to solve the problem that the existing temporary construction guardrail structure is not suitable and improve the driving safety of vehicles.
