Problems solved by technology

[0004] One of the existing municipal road guardrails includes a railing and a base, which are set on the road for separation, and the base is provided with mounting holes, and the installation method is to connect expansion screws on the road surface. The municipal road guardrail The material is generally soft, and the railing and base are generally made of plastic, resin and PVC, so that it will not have too much impact on people and cars if it is hit; after a long time of use, or being hit by a car, the municipal road guardrail will be damaged. It needs to be updated; the way to update is to pull out the original expansion screw and re-install the expansion screw at another place on the road until there is no place to drill, so that the road surface will be repaired; or nail the original expansion screw installation hole , in this way, the installation is inconvenient, and the damage to the road surface is more serious

Embodiment 1

[0025] Such as figure 1 , 2 , 3, the municipal road guardrail described in this embodiment includes a railing 1 and a circular base 2, and the base 2 is provided with mounting holes 3 distributed in a circle; 131 and the perforation 132 located at the bottom; it is characterized in that a pre-embedded pipe 4 pre-buried in the road 10 is arranged under the installation hole 3, such as Figure 4 , 5 As shown, the inner chamber of the embedded pipe 4 is divided into an upper chamber 5 and a lower chamber 6 by a step 15, and the inner diameter of the upper chamber 5 is smaller than that of the lower chamber 6; a hollow pipe 8 with a flange 7 on the top is provided in the embedded pipe 4; The hollow tube 8 passes through the perforation 132, and the flange 7 is located in the reaming hole 131. There is a gap between the hollow tube 8 and the inner wall of the upper cavity 5, and the gap is generally 2-3 mm. The lower part of the tube 8 is provided with a plurality of bead holes ...

Embodiment 2

[0038] Such as Figure 6 As shown, the municipal road guardrail described in this embodiment is different from Embodiment 1 in that: the bottom surface of the flange 7 is provided with teeth 26, the existence of the teeth 26, the flange 7 is stressed during disassembly, and the flange 7 below The base part is easier to crush and easy to disassemble.

Embodiment 3

[0040] The construction method of another kind of municipal road guardrail designed by the present invention is characterized in that comprising the following steps:

[0041] Embed the pre-embedded pipe 4 in the road 10, and the position of the pre-embedded pipe 4 corresponds to the installation hole 3;

[0042] Set the municipal road guardrail on the road 10 so that the installation hole 3 corresponds to the position of the embedded pipe 4;

[0043] Put the ball 11 into the bead hole 9 on the inner wall of the hollow tube 8, insert the hollow tube 8 into one of the mounting holes 3

[0044] And in the embedded pipe 4;

[0045] Nail 12 is inserted in the hollow pipe 8;

[0046] Adopt a pressing device 17, such as Figure 7 Shown, this hold-down device 17 is made of vertical bar 18, upper arc-shaped bar 19, lower arc-shaped bar 20, supporting foot 21, slip ring 22 and staving 23, and vertical bar 18 is left and right two, and every vertical bar 18 A said slip ring 22 is arran...

Abstract

The invention discloses a municipal road guardrail. The municipal road guardrail comprises a rod and a round base, and the base is provided with mounting holes formed in the circumferential direction.Each mounting hole comprises an expanding hole in the upper part and a through hole in the lower part. The municipal road guardrail is characterized in that the lower portion of each mounting hole isprovided with a pre-buried pipe embedded in a road, an inner cavity of each pre-buried pipe is divided into an upper cavity and a lower cavity by a step, and hollow pipes with flanges at the tops arearranged in the pre-buried pipes; the hollow pipes penetrate through the through holes, the flanges are located in the expanding holes, a plurality of ball holes running through the inner walls of the hollow pipes are formed in the lower parts of the hollow pipes, and balls are arranged in the ball holes; and the distance between each hollow pipe and the inner wall of the corresponding lower cavity is smaller than the diameter of the balls. The invention further discloses a construction method of the municipal road guardrail. The municipal road guardrail has the beneficial effects that when the municipal road guardrail is damaged and needs to be replaced, all the pre-buried pipes, the hollow pipes, the balls and nails can be repeatedly used, the road surface is free of cracks, and the road surface does not need to be maintained frequently.

Description

[0001] This patent application is a divisional application of an invention patent application (application number 201610103978X, titled "A Municipal Road Guardrail and Its Construction Method", and application date is 2016-2-25) technical field [0002] The invention relates to a municipal road, in particular to a municipal road guardrail. Background technique [0003] The municipal road guardrail is set on the road to partition and divert traffic. [0004] One of the existing municipal road guardrails includes a railing and a base, which are set on the road for separation, and the base is provided with mounting holes, and the installation method is to connect with expansion screws on the road surface. The municipal road guardrail The material is generally soft, and the railings and bases are generally made of plastic, resin and PVC, so that they will not have too much impact on people and cars if they are hit; after using for a long time, or being hit by a car, the munici...
