Secondary transformation concrete guardrail structure and construction method for heightening guardrail structure
The invention relates to the technical field of road administration construction, in particular to a secondarily-transformed concrete guardrail structure and a construction method for heightening the guardrail structure. The guardrail structure comprises a lower guardrail and an upper guardrail, the lower guardrail is provided with an opening extending to the stratum, and the upper guardrail comprises a supporting leg inserted into the opening and a guardrail part integrally arranged at the top of the supporting leg; the supporting legs are integrally supported on the ground layer, the guardrail part is located on the upper side of the lower guardrail, and gaps are formed between the supporting legs and the lower guardrail. A lower positioning part is arranged at the top of the lower guardrail, an upper positioning part is arranged at the bottom of the guardrail part, a first vibration isolation gap is formed between the upper positioning part and the lower positioning part, and the upper positioning part can be matched with the lower positioning part when transversely moving relative to the lower positioning part so as to stop the guardrail part from transversely moving relative to the lower guardrail. By improving the heightening structure and the construction method of the guardrail, the guardrail is not prone to being damaged by vibration after being heightened, the strength is not affected, connection can be stable, and the problems existing in the prior art are effectively solved.
本发明涉及路政施工技术领域，尤其是一种二次改造的混凝土护栏结构及护栏结构增高的施工方法，护栏结构包括下护栏、上护栏，下护栏设有延伸至地层的开口，上护栏包括插入开口的支撑腿、一体设置于支撑腿顶部的护栏部，支撑腿一体支撑在地层，护栏部位于下护栏的上侧，支撑腿与下护栏之间设有间隙；下护栏的顶部设有下定位部，护栏部的底部设有上定位部，上定位部和下定位部之间设有第一隔振间隙，且上定位部在相对下定位部横向移动时能够与下定位部配合，以止动护栏部相对下护栏横向移动。本发明通过改进护栏增高的结构和施工方法，可使得护栏增高后不易受振动破坏影响强度，还可连接稳定，有效的解决了现有技术中存在的问题。
