Embodiment 1
[0043] like figure 1 As shown, a new wall fence structure for highways, including the base 1 and several set on the base 1, the barrier unit 2, the base 1 is set along the edge of the road, the basal 1 The concrete is poured, and the base 1 is provided with a steel network to improve the structural strength of the base 1.
[0044] like figure 1 , 2 As shown, the retaining plate unit 2 includes a fixing plate 21, an elastic assembly, and a movable plate 23, and the fixing plate 21 is fixed to the base 1, and the movable plate 23 is active on the base 1, and the movable plate 23 is close to the highway with respect to the fixed plate 21. Middle line settings. The resilient assembly is disposed between the movable plate 23 and the fixing plate 21, and the adjacent two-stop wall unit 2 is further fixed, and the column 11 is disposed, the column 11 is fixedly disposed on the base 1, and inserted into the base 1.
[0045] Among them, if figure 2 , 3As shown, the elastic assembly include...
Embodiment 2
[0059] A new wall guardrail construction method for highways, including the following steps:
[0060] S1, pouring concrete base 1, and inserts the fixing pile 212 vertically into the foundation, and evenly mount the column 11 along the longitudinal direction of the road, the bottom of the column 11 is inserted into the foundation 1;
[0061] S2, after the foundation 1 is solidified to reach the strength, the fixing plate 21 is attached to the top of the base 1, and the fixing plate 21 is fixedly fixed;
[0062] S3, press the retaining wall unit 2 in turn, and finally secure the housing 7 on the base 1.

Abstract
The invention relates to a novel wall-type guardrail structure for highways and a construction method thereof, belonging to the technical field of highway protection, comprising a foundation arranged along the length direction of the road and a plurality of retaining wall units arranged on the foundation, the retaining wall unit includes a fixed plate, an elastic Components and movable panels, the fixed panel is fixed on the foundation, the movable panel is movable on the foundation, the elastic component is installed between the movable panel and the fixed panel, and a column is fixedly installed between the adjacent two retaining wall units, and the column and the movable rod Elastic parts are connected between the boards. When the vehicle runs out of control and hits the retaining wall unit, the vehicle hits the movable plate, and the movable plate is impacted and moves close to the fixed plate. The elastic component plays the role of buffering and absorbing energy, and the elastic part on the column acts as a further buffer limit The effect of improving the overall impact resistance, reducing the injury of vehicles and personnel, and improving safety performance.
Description
Technical field [0001] The present invention relates to the field of road protection, and in particular, to a new wall guardrail structure for highways and a construction method thereof. Background technique [0002] At present, the guardrails are often set on both sides of the road. As one of the important safety protection facilities of the road, there is an important role in the security of road traffic safety. Wall fence is currently widely used in the form of road fence. [0003] At present, the highway wall guardrail uses reinforced concrete structures, just over, the energy is poor, and the anti-collision performance is poor, resulting in traffic accidents to the vehicle and driving damage. Inventive content [0004] One of the objects of the present invention is to provide a new wall guardrail structure for highways, with an advantage of improving collision performance and security. [0005] The above techniques of the present invention are achieved by the following tech...
