Novel concrete base safety guard device

Abstract

The invention discloses a novel concrete base safety guard device, comprising a base and a vertical post arranged in the base; the base is made of cast-in-place concrete or pre-made in a factory; thebase is integrated to a subgrade; a reinforcing cage is embedded in the base; a post cavity is arranged in the base; a post sleeve is pre-arranged on the inner periphery of the post cavity and is fixedly connected with the reinforcing cage; the upper peripheral rig of the post sleeve is fixedly connected with a reinforcing disc, the lower peripheral edge of the post sleeve is provided with a drainpassage, a plurality of limiting blocks are fixed to the inner wall of the post sleeve, and a plurality of damping seal rings are arranged between the inner wall of the post sleeve and the vertical post from top to bottom. The novel concrete base safety guard device has the advantages that the damaged vertical post is quick to change so that operating time is effectively shortened for construction staff; the novel concrete base safety guard device is well compatible with current standard facilities and is highly applicable; materials selected herein are common, the novel concrete base safetyguard device is simple to manufacture and widely applicable, and the vertical post in a vertical tube can be protected from damage so that reusing is achieved; the novel concrete base safety guard device is solid, durable, economical and reliable, and low in cost.

Description

technical field [0001] The invention relates to the field of highway safety protection, in particular to a novel concrete base safety guardrail device. Background technique [0002] At present, my country's highway safety guardrail generally adopts steel column and wave beam structure, which greatly improves the protection level and reduces the occurrence of accidents. It is very practical in areas with less accidents and less maintenance, but in the vast Midwest, especially in mountainous areas, where sharp bends and downhill roads are the most common and accident-prone, this process is still used for the construction and maintenance of guardrails. It is far from meeting the actual needs. [0003] If the column encounters hard pebbles and rock formations when it is driven in, the middle and lower part of the column will be skewed, trumpet-shaped and torn and twisted, like a big tree root. The soil and rocks are carried out and loosened, which not only increases the difficul...

Problems solved by technology

[0007] Therefore, the commonly used methods of directly driving piles and extracting piles and existing replaceable guardrails connected by flanges and bolts can no longer meet the needs of road maintenance on accident-prone sections in western mountainous areas. , At the same time, it can be well compatible with the current standard facilities, and it is a low-cost road safety protection device
