Description

Technical Field

[0001] The utility model belongs to the field of traffic protection facilities, and particularly relates to a wind barrier. Background Art

[0002] Tunnels and expressways are important components of modern traffic infrastructure. However, under certain specific geographical and meteorological conditions, areas such as intersections, tunnel entrances and exits, and mountain expressways are often severely affected by wind. During the operation of high-speed trains, they are vulnerable to the influence of lateral winds. Under the action of strong crosswinds, the train will run unstably, and in severe cases, it may lead to derailment. To mitigate these adverse effects, the concept of a wind barrier is introduced.

[0003] Most of the existing wind barriers are applied in the field of bridges, and there is relatively little research on wind barriers when high-speed trains encounter significant crosswinds at the tunnel exits. Most of the existing wind barriers are fixed, that is, along the direction of train advancement, the porosity of the wind barrier remains unchanged. However, when the train is running at high speed, as the air resistance increases, it will increase the air resistance of the train, resulting in increased energy consumption and reduced operation efficiency. On the other hand, fixed wind barriers are usually made of durable materials, but they may still require regular inspections and maintenance under external impacts or harsh weather conditions, and the maintenance process may be relatively difficult. It cannot meet the requirements of lightweight and convenient construction to reduce project costs, and the fixation is not stable and fast enough.

[0004] Therefore, it is necessary to propose a suitable wind barrier to solve the problems existing in the prior art, improve the construction convenience of the wind barrier and reduce costs, and provide a safer, more stable and efficient traffic environment. Content of the Utility Model

Specific implementation mode

[0025] The embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. However, the present utility model can be implemented in many different ways as defined and covered by the claims.

[0026] Embodiment:

[0027] Refer to Figure 1 and Figure 2 , a wind barrier, including wind barrier units 2 arranged on both sides of the road 1; the wind barrier unit 2 includes a plurality of columns 2.1 and a plurality of wind baffles 2.2; the plurality of columns 2.1 are arranged on the ground at intervals along the length direction of the road 1, and adjacent two columns 2.1 are connected by a plurality of wind baffles 2.2; a plurality of mounting holes 2.3 are arranged on the column 2.1 at intervals in the vertical direction, and both ends of the wind baffle 2.2 are respectively connected to adjacent two columns 2.1 through the mounting holes 2.3.

[0028] By arranging the mounting holes at intervals and connecting the wind baffle to the column through the mounting holes, the stability of the connection between the columns is ensured, the connection is convenient, and materials can be saved. It is convenient to quickly set up a wind barrier with good stability on both sides of the road.

[0029] The setting of a plurality of mounting holes facilitates the subsequent setting of different numbers of wind baffles. Combined with the above structure of the wind baffle, even if different ventilation rates are required, there is no need to reprocess the wind baffle and the column, which is convenient for quick construction and installation and has a wide range of applications.

[0030] The number of wind baffles 2.2 between different columns 2.1 is different, and the number of wind baffles 2.2 increases or decreases along the length direction of the road 1. The number of wind baffles 2.2 between the plurality of columns 2.1 is set according to the ventilation rates of 20%, 40%, 60% and 80% in sequence. By controlling the number of wind baffles, the ventilation rate between the columns is controlled, so that the wind barrier can quickly and conveniently have a gradually changing ventilation rate. The gradually changing ventilation rate is beneficial to improving the windproof effect of the wind barrier and ensuring its service life.

[0031] Due to the adoption of the gradually changing ventilation rate design, during the operation of the train, gradually increasing air flow is allowed to pass through, reducing the blockage of the wind barrier to the wind field and improving the windproof effect. According to the improved delayed detached eddy simulation method, the turbulent flow is simulated and analyzed to determine the length dimension of the wind barrier. Taking the CRH380B high-speed train as an example, among them, when the length of each wind barrier unit is 25m and the total length is 100m, the structural windproof is the most stable and the integrity is better.

[0032] The wind baffle 2.2 is arranged parallel to the ground. The wind barrier arranged parallel to the ground is also perpendicular to the column, which is convenient for improving the connection of the adjacent two columns by the installation holes.

[0033] The column 2.1 is fixed on the ground through the base 2.4, and the base 2.4 is integrally formed or detachably connected with the column 2.1. By integrally forming or detachably connecting the base with the column, the column is fixed on the ground, which is convenient for installation and beneficial to improving the stability of the column.

[0034] See Figure 3 , an extension part 2.5 is further arranged on one side of the base 2.4 away from the road 1, and a reinforcing rib plate 2.6 is further arranged between the extension part 2.5 of the base 2.4 and the column 2.1. By extending the base along the width direction of the road, the base has an enlarged foundation on the leeward side, which improves the stability of the base, thereby improving the wind resistance and anti-overturning ability of the whole wind barrier. The reinforcing rib plate ensures the connection strength between the base and the column.

[0035] See Figure 4 , the column 2.1 is an I-beam cast with concrete, and the installation hole 2.3 is arranged on the web 2.7 of the I-beam. The wind baffle 2.2 is detachably connected with the flange 2.8 of the I-beam through bolts 2.9. Through the above arrangement, the I-beam shape reduces the material use of the column while also improving the strength of the column. The wind baffle is first positioned and fixed on the column through the installation hole, and then further fixed by bolts passing through the two flanges of the I-beam and the wind baffle at the same time.

[0036] The shape of the wind baffle 2.2 is rectangular. The rectangular wind baffle can have a good energy dissipation effect on the oncoming flow.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. For those skilled in the art, the present invention can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
