Description

Technical Field

[0001] The utility model relates to a vehicle control device for the pavement construction of a newly built two-way four-lane expressway, which is used for vehicle control during the pavement construction to ensure traffic safety during the expressway pavement construction. Background Art

[0002] The construction of newly built expressway pavements generally consists of two to three layers of cement gravel base with a certain gradation, and two to three layers of asphalt surface. During pavement construction, the roadbed has already been completed and inspected, and traffic conditions are good. Transport vehicles, rolling equipment, and management vehicles are numerous, and road markings cannot be applied until the asphalt top layer is completed. Furthermore, due to the tight construction schedules typically associated with newly built expressways, pavement construction often overlaps with mechanical and electrical engineering, traffic safety, and other projects. These factors, coupled with the high speeds and unclear routes of various vehicles, have always been key and challenging aspects of safety management during new expressway pavement construction, making traffic accidents highly likely to occur during construction.

[0003] During highway pavement construction, the current control measures used to address the difficulty of controlling vehicles include traditional management measures, such as strengthening safety education for operators of various vehicles to continuously improve their safety awareness, and placing speed limit and guidance warning signs in conspicuous locations to remind operators to operate within these limits. These management measures require operators to possess high safety awareness and operational skills. Another type of management measure involves proactive measures, such as using water barriers and crash barrels to set up a certain number of S-shaped roadblocks to force vehicles to reduce their speed. These management measures require sufficient safety investment, and water barriers and crash barrels are susceptible to vandalism, requiring multiple daily inspections and restoration by dedicated personnel. Practice has proven that these measures have played a role in controlling various vehicles during pavement construction. However, due to factors such as uneven safety awareness and operational skills among operators of various vehicles and insufficient investment in safety production funds, the current control of various vehicles during new highway pavement construction still has loopholes and shortcomings. Summary of the Invention

[0004] The purpose of the utility model is to provide a traffic control device for the construction of a newly built highway pavement. This device is simple to install and disassemble, reusable, inexpensive, and not easily damaged by human intervention. The device can not only effectively close roads and cross-operation areas, but also can conspicuously induce various types of vehicles to actively slow down and travel along designated routes by placing S-shaped roadblocks, thereby effectively controlling various types of vehicles during the pavement construction process.

[0005] The purpose of the utility model is achieved by the following design: First, the design of a single traffic control device, a single traffic control device consists of a rectangular concrete block, 2 groups of connecting devices consisting of a steel pipe and a pair of T-shaped tee joints with equal diameters of the steel pipe welded together, the height of the concrete rectangular block is 0.8m to 1.2m, the length and width are 0.1m to 0.3m, the 2 groups of connecting devices are welded together by a steel pipe with a diameter of 0.03m and a pair of T-shaped tee joints with a diameter of 0.03m, the length of the steel pipe is 0.1m to 0.3m, and the T-shaped tee joint is used to connect the parts The length is 0.05m~0.15m, and the two ends of the steel pipe are respectively fixed to a pair of T-shaped tees at the center of their horizontal connection parts by vertical welding. The two sets of connecting devices are cast in the center of the rectangular concrete block from ⅓ to ⅔ from high to low. At half the distance from the three connection ports of the T-shaped tees, two circular holes are vertically cut with a diameter of 0.005m~0.015m for the connection of traffic control devices. The second is the connection between traffic control devices. The traffic control devices are connected through two steel pipes with a diameter of 0.0275m and a length of 6m~12m. For the bolts and two locks, two circular holes are cut vertically with a diameter of 0.005m to 0.015m at a distance of 0.02m to 0.08m from the ends of the two steel pipes, which are used to fix the two circular holes of the T-shaped tee with bolts. The diameter of the two pairs of bolts is 0.7 to 0.9 times the diameter of the circular holes on the two steel pipes, and the length of the bolts is 0.05m to 0.1m. A circular hole is cut with a diameter of 0.5 to 0.8 times the diameter of the bolt at a distance of 0.005m to 0.015m from the ends of the bolts for installing the locks. Third, a single-lane closure of a newly built expressway And a set of S-shaped speed limit barriers are realized by using the above-mentioned two traffic control devices and four 12-meter-long steel pipes, which are fixed by bolts and locks, and placed vertically with a single-lane newly built expressway, which can prevent all kinds of vehicles from traveling on the road; through six traffic control devices and 12 8-meter-long steel pipes, of which two traffic control devices are connected with four 8-meter-long steel pipes, which are fixed by bolts and locks, three pairs can be obtained, with each pair separated by 10m to 30m, of which one pair is close to the inside of the road surface, and the front and rear pairs are close to the outside of the road surface, that is, a set of S-shaped roadblocks.

[0006] The beneficial effects of the present invention are: it effectively solves the current problem of difficult traffic control during the construction of a new highway pavement. By designing a traffic control device for the construction of a new two-way four-lane highway pavement, the road surface can be closed in a single lane and various types of vehicles can be guided to travel in an orderly and reduced speed according to the needs of on-site road construction safety management. It can also prevent easy human damage, greatly improving the control efficiency of various types of vehicles during the construction of a new two-way four-lane highway pavement, and curbing the occurrence of various traffic accidents during the construction of the pavement from the source.
