Problems solved by technology

[0002] my country promulgated the "Construction Standards for Road Airstrips" in 1994, which provided a basic basis for the construction of roads and airstrips. However, compared with the end of the 20th century, the current main combat aircraft of our army has undergone tremendous changes, and the relevant standards have not been revised in time. However, the survey, design and construction of road runway construction projects have not been standardized. These expressways have the dual functions of traffic readiness emergency airport and expressway ground transportation. The measure is to remove the green belt and obstacles in the middle of the road and turn it into a temporary runway to meet the takeoff and landing requirements of fighter jets. However, the expressway is currently shared with the aircraft takeoff and landing runway, and ordinary wall guardrails are still used. When the expressway is used as a runway, it will be demolished. It is inconvenient to install, and there are problems such as slow disassembly speed and easy damage; when the expressway needs to be used as an airstrip, how to quickly remove the concrete guardrail from the runway is a difficult problem; therefore, it is necessary to provide a reasonable structure, high safety, reliable work, It is very necessary to use a movable concrete movable guardrail structure with various uses

Abstract

The invention relates to a movable concrete movable guardrail structure. The structure comprises a standard New Jersey concrete guardrail, an outer surrounding body is arranged on the outer side of the standard New Jersey concrete guardrail, outer brims are arranged on the upper portion of the outer surrounding body, a guide arc is arranged in the middle of the outer surrounding body, a groove isformed in the inner side of the lower portion of the standard New Jersey concrete guardrail, and holes are formed in the two sides of the groove of the standard New Jersey concrete guardrail. The structure has the advantages of being reasonable in structure, high in safety, reliable in work and diverse in purpose.

Description

Technical field [0001] The invention belongs to the technical field of guardrails, and particularly relates to a movable concrete movable guardrail structure. Background technique [0002] China promulgated the "Highway Airstrip Engineering Construction Standards" in 1994, which provided a basic basis for the construction of highways airstrips, but the current main combat models of our army have undergone tremendous changes compared with the end of the 20th century, and the relevant standards have not been revised in time. The survey, design and construction of highway airstrip construction projects have not been standardized. These highways have the dual functions of traffic preparedness emergency airport and highway ground transportation. They are usually used as highways and can be passed through in wartime or emergency situations. Measures to remove the green belt and obstacles in the middle of the road and turn it into a temporary runway to meet the requirements of aircraft ...
