Structure of prefabricated road shoulder and construction method thereof

Abstract

The invention discloses a structure of a prefabricated road shoulder and a construction method thereof. According to the structure of the prefabricated road shoulder, more than one vertical through holes are formed in bases; more than one wire through holes running through the left and right ends and used for steel strands to penetrate through are formed in the vertical wall surfaces of prefabricated road shoulders A; more than one wire through holes running through the left and right ends and used for steel strands to penetrate through are formed in the vertical wall surfaces of prefabricatedroad shoulders B, and pulling grooves communicating the wire through holes are formed in the vertical wall surfaces of the prefabricated road shoulder B; and more than one wire through holes runningthrough the left and right ends and used for steel strands to penetrate through are formed in the vertical wall surfaces of prefabricated road shoulders C, and internal chamber angles are arranged onthe two sides of the bases and the vertical wall surfaces. According to the structure of the prefabricated road shoulder, the structure of the road shoulder can be enhanced, the construction period can be shortened, materials can be saved, and the structure of the prefabricated road shoulder is beneficial for environmental protection.

Description

technical field [0001] The invention relates to a prefabricated road shoulder structure and a construction method thereof, belonging to the field of road shoulder tools. Background technique [0002] On both sides of existing road slopes or mountain top roads, road shoulders composed of guardrails or anti-collision walls are often seen, which play a great role in guaranteeing the life safety of passengers or drivers. [0003] However, there are some problems in the existing road shoulders, which are mainly reflected in the structure and construction. Specifically, in the construction: in the construction process of the existing slope road, it is generally first to pile up the road shoulder walls on the left and right sides of the roadbed, and then Lay a water-stabilized layer made of mortar on the subgrade between the two shoulder walls, lay an asphalt layer on top of the water-stabilized layer, and finally pour guardrails or anti-collision walls on both sides of the road as...

Problems solved by technology

[0003] However, there are some problems in the existing road shoulders, which are mainly reflected in the structure and construction. Specifically, in the construction: in the construction process of the existing slope road, it is generally first to pile up the road shoulder walls on the left and right sides of the roadbed, and then Lay a water-stabilized layer made of mortar on the subgrade between the two shoulder walls, lay an asphalt layer on top of the water-stabilized layer, and finally pour guardrails or anti-collision walls on both sides of the road as road shoulders, and anti-collision walls are generally made of steel bars Integral pouring of concrete or splicing of prefabricated shoulder blocks. In this way, first, when the guardrail or anti-collision wall is poured at the end, the poured concrete usually spreads or scatteres to the surroundings, which not only causes waste of materials, but also It is not easy to pollute the surrounding environment, and it is not easy to clean up the concrete after the solidification of the scattered shoulder walls at the end; secondly, in the construction process, it is generally necessary to wait for the shoulder walls to have a certain strength before pouring the water-stabilized layer. Time-consuming, at the same time, the construction time and solidification time of the reinforced concrete composition are relatively long, and it is also time-consuming

Structurally: the road shoulders are set in the final stage, so the structural stability of the connection between the road shoulders and the whole is poor
