Problems solved by technology

[0004] The above-mentioned existing technical solution has the following defects: when the spring is compressed to the point where the steel wires of two adjacent coils abut, the maximum compression state of the spring is reached, and it can no longer play a buffering role
Therefore, when the speed of the vehicle is fast or the tonnage of the vehicle is large, the guardrail cannot play a good protective effect

Embodiment 1

[0046] Such as figure 1 As shown, a highway life safety system includes a plurality of fixed piles 1 for fixing on the road and a buffer mechanism 2 connected to the fixed piles 1 .

[0047] Such as figure 1 As shown, the fixed pile 1 is a cylinder, and the lower end of the fixed pile 1 is inserted into the road and closely connected with the concrete road. The height of the fixed pile 1 beyond the road part is 10-15cm, which is lower than the chassis height of general automobiles.

[0048] Such as figure 2 and image 3As shown, the buffer mechanism 2 includes a slide rail 3 welded on the side of the fixed pile 1, a movable column 4 moving along the slide rail 3, an elastic assembly 5 connecting the fixed pile 1 and the movable column 4, and connecting between adjacent movable columns 4 The bar 6. The slide rail 3 is fixed along the horizontal direction, and the upper surface of the slide rail 3 is provided with a slide groove 7, and the two side walls of the slide groov...

Embodiment 2

[0053] A construction method for the above highway life safety system, comprising:

[0054] A. Excavation of foundation pit

[0055] Excavate a foundation pit every 3 meters on both sides of the road. The foundation pit is excavated from both sides of the roadway to the sidewalk side with a length of 1 meter. The width of the foundation pit is 0.2 meters.

[0056] B. Buried fixed pile 1, slide rail 3 and movable column 4

[0057] The movable column 4 is snapped into the slide rail 3 through the slide block 11, and the fixed pile 1, the slide rail 3 and the movable column 4 are buried together in the foundation pit. The gravel cushion is filled through the bottom of the foundation pit so that the upper surface of the shielding plate 13 is flush with the upper surface of the road.

[0058] C. Building wooden formwork

[0059] The first wooden template comprises a horizontal section and a vertical section connected to the lower side of the horizontal section middle part, the l...

Abstract

The invention relates to the technical field of road safety facilities, in particular to a road life safety system and a construction method thereof. A highway life safety system, comprising a plurality of fixed piles for fixing on the road and a buffer mechanism connected to the fixed piles, the height of the fixed piles above the ground is less than 15cm, and the buffer mechanism includes Slide rails to one side of the roadway, movable columns that slide rails move, elastic components connecting fixed piles and movable columns, and cross bars connected between adjacent movable columns. When the horizontal rail and the movable column move away from the fixed pile, the elastic component stretches to absorb and transform the kinetic energy, so as to avoid the danger of the vehicle. Since the stretching of the elastic component is not limited at this time, it can adapt to the kinetic energy of the vehicle and convert more kinetic energy into elastic potential energy, and the buffer distance is longer, so the protection effect is better.

Description

technical field [0001] The invention relates to the technical field of road safety facilities, in particular to a road life safety system and a construction method thereof. Background technique [0002] At present, the road is protected by a continuous structure of steel guardrails spliced ​​with each other and supported by the main column. The vehicle can absorb energy when it collides with it, and at the same time it is not easy to be crashed, which can protect the vehicle and the passengers. . [0003] The utility model patent whose authorized notification number is CN206941474U discloses a highway guardrail, which acts as a buffer through the cooperation of springs and auxiliary guardrails to protect vehicles that hit the guardrail. [0004] The above-mentioned prior art solution has the following defects: when the spring is compressed to the point where the steel wires of two adjacent coils abut, the spring reaches the maximum compression state and can no longer play a...
