Description

Technical Field

[0001] The present application relates to the field of municipal engineering technology, and in particular to a pavement structure with a guardrail that is easy to replace. Background Art

[0002] During the construction of municipal engineering projects, in order to distinguish between forward and reverse rail transit and separate traffic surfaces, separation guardrail structures will be installed between roads of different natures. While distinguishing the roads, it effectively reduces the probability of head-on collisions and injuries caused by traffic accidents.

[0003] In the existing municipal system, guardrails are generally fixed to the ground with expansion screws: the guardrails are composed of columns arranged at intervals and partitions connecting adjacent columns. The two ends of the partitions are fixed to the corresponding columns. Metal plates are fixed to the bottom of the columns, and through holes are opened on the metal plates. When installing the guardrails, holes are first drilled in the ground, and then the metal plates are fixed to the ground with expansion screws to fix the guardrails.

[0004] However, during use, it was found that since the guardrails are installed in sections, the columns and barriers on a certain length of the guardrail are connected together. If the barrier part of the guardrail is damaged, the entire guardrail needs to be replaced. Disassembling the guardrail is rather troublesome and needs to be improved. Utility Model Content

[0033] The following is combined with Figure 1-4 This application is described in further detail.

[0034] The present application embodiment discloses a road surface structure with a guardrail that is easy to replace. Figure 1 The pavement structure with a guardrail that is easy to replace includes a pavement body 1 and a guardrail 2 installed on the pavement body 1. The pavement body 1 includes a two-way road 101 with opposite driving directions and a non-motorized vehicle lane 102 arranged on both sides of the two-way road 101. The guardrail 2 is installed in the middle of the two-way road 101 to separate the two-way road 101, and a guardrail 2 is also installed between the two-way road 101 and the non-motorized vehicle lane 102.

[0035] Reference Figure 1 and Figure 2 The guardrail 2 includes a mounting column 201 and a barrier 202, wherein the barrier 202 connects adjacent mounting columns 201. A mounting seat 3 is fixed on the pavement body 1, and a mounting hole 4 is provided on the mounting seat 3. The mounting hole 4 is used for an expansion screw to pass through, and the expansion screw fixes the mounting seat 3 to the pavement body 1. The mounting seat 3 is provided with a mounting groove 5 for accommodating the mounting column 201, and a rubber block 6 is fixed on the groove wall of the mounting groove 5, and the rubber block 6 is pressed against the outer wall of the mounting column 201. The end of the mounting column 201 close to the mounting seat 3 is chamfered 7.

[0036] Reference Figure 1 and Figure 3 The fence 202 includes two connecting rods 2021 and a plurality of reinforcing rods 2022. The connecting rods 2021 connect adjacent mounting columns 201. Both ends of the reinforcing rods 2022 are respectively connected to the connecting rods 2021. The number of the reinforcing rods 2022 is determined according to needs.

[0037] Reference Figure 1 and Figure 4 A mounting block 8 is fixed on the opposite side of the mounting column 201, and the mounting block 8 includes a limit plate 81 and a support plate 82. The support plate 82 extends in the horizontal direction, and the limit plate 81 is fixed on both sides of the support plate 82. The opposite sides of the limit plates 81 are parallel to each other, and the opposite sides of the limit plates 81 are perpendicular to the top surface of the support plate 82.

[0038] Reference Figure 3 and Figure 4A connecting groove 9 for accommodating the reinforcing rod 2022 is provided on the opposite side of the connecting rod 2021. When the end surface of the reinforcing rod 2022 abuts against the groove wall of the connecting groove 9, the bottom surface of the connecting rod 2021 abuts against the support plate 82.

[0039] Reference Figure 1 and Figure 4 A limit block 10 is installed on the mounting block 8, and a receiving groove 11 is provided on the mounting block 8 for receiving the limit block 10. When the limit block 10 is received in the receiving groove 11, the bottom surface of the limit block 10 is pressed against the connecting rod 2021.

[0040] The implementation principle of the pavement structure with a guardrail that is easy to replace in an embodiment of the present application is as follows: a mounting seat 3 is provided for the mounting column 201 to be installed, and the mounting column 201 is embedded in the mounting groove 5 to be fixed to the mounting seat 3, thereby being fixed to the pavement body 1, so that the guardrail 2 is fixed to the pavement body 1. Since there is no fixed relationship between the mounting columns 201, they are only connected by the splicing relationship between the partition 202 and the mounting column 201. If a section of the guardrail 2 is damaged, only the guardrail 2 needs to be replaced. If the mounting column 201 is damaged, the mounting column 201 can be taken out and a new mounting column 201 can be embedded. There is no need to remove a large number of expansion screws, and the tediousness of continuous drilling is avoided. The problem of the troublesome replacement of the guardrail 2 is improved, the replacement efficiency of the guardrail 2 is improved, and materials are saved.
