Problems solved by technology

[0004] In the actual implementation process, this method has at least the following problems: ① Due to the need to dismantle and reinstall, the cost is high and the construction is complicated
②Because most of the wave beam guardrails are installed on the hardened road shoulders, when the guardrail columns are pulled out, the road shoulders will be damaged, and the holes left after the columns are pulled out will accumulate and soak the roadbed after rain, affecting the stability and safety of the roadbed
③ Columns installed on concrete structures such as retaining walls or shoulder guards cannot be pulled out, and can only be cut by machinery, which is inconvenient for construction
Therefore, this method has a big flaw

Embodiment 1

[0044] Such as figure 1 As shown, a road guardrail includes a column 1, an anti-blocking block 2 and a corrugated beam plate 3, the anti-blocking block 2 is arranged on the column 1, and the column 1 is a hollow structure with an upper end opening; the corrugated beam plate 3 is arranged on the anti-blocking block 2 on.

[0045] Such as figure 2 , 3As shown, the column 1 is provided with a mounting hole 11 along the vertical direction, and an adjusting block 4 is slidingly arranged in the column 1 along the length direction of the mounting hole 11; The positioning assembly 5 includes a positioning bolt 51 and a positioning nut 52 . An adjustment hole 41 penetrating through the adjustment block 4 is opened on the adjustment block 4 , and a positioning bolt 51 is passed through the adjustment hole 41 . The side wall of the anti-blocking block 2 is provided with a positioning hole 21 for the positioning bolt 51 to pass through, and the positioning bolt 51 passes through the ...

Embodiment 2

[0059] A construction method for a road guardrail, comprising the following steps:

[0060] S1. Stakeout, under the responsibility of the engineer, according to the requirements of the design drawings, carry out stakeout according to the construction layout drawing;

[0061] S2. Piling of column 1 and excavation of foundation pit. After the sample is placed, piling of column 1 and excavation of foundation pit of column 1 are carried out according to the sample line;

[0062] S3, bury pile, bury column 1;

[0063] S4. Install the guardrail. The guardrail components should be erected according to the design drawing, and a smooth and continuous installation effect should be achieved. All lap joints should be spliced ​​in the direction of the vehicle;

[0064] S5. Guardrail adjustment, under the supervision of the engineer, adjust the overall line shape of the guardrail. The top surface of the wave beam should be in harmony with the line shape of the road. After the adjustment, t...

Abstract

The invention relates to a highway guardrail and a construction method thereof, belonging to the technical field of road construction, comprising a column, an anti-blocking block and a corrugated beam plate, the anti-blocking block is arranged on the column, and the corrugated beam plate is arranged on the anti-blocking block , the column is provided with a mounting hole along the vertical direction, and an adjustment block is slidably arranged in the column along the length direction of the installation hole, and a positioning assembly for limiting the position of the anti-blocking block and the adjustment block is arranged on the adjustment block. When the height of the corrugated beam slab needs to be adjusted after the road surface is raised, first remove the restriction of the positioning component on the corrugated beam slab, and then move the adjusting block and the anti-blocking block together along the installation hole, and after moving to the specified position, pass the positioning component The positions of the adjusting block and the anti-blocking block can be fixed; the purpose of adjusting the height of the corrugated beam plate is realized, and the construction is convenient and the cost is low.

Description

technical field [0001] The invention relates to the technical field of road construction, in particular to a road guardrail and a construction method thereof. Background technique [0002] my country's road construction has gone through a period of rapid development, and the roads that were built and put into operation in the early stage have gradually entered the period of overhaul. With the rapid growth of automobile traffic in recent years, it will become an important task for the road maintenance department to increase the traffic volume of existing roads through major and medium road repairs. [0003] In the process of pavement overhaul, in order to ensure that the road meets the rapidly growing traffic volume, the pavement structure of the road is rebuilt. After the road surface is paved, the elevation of the road surface will increase, resulting in the height of the wave beam guardrail set on the original road not meeting the specification requirements, and it needs ...
