Windproof reinforced concrete rod sleeve base

Abstract

The invention discloses a windproof reinforced concrete rod sleeve base which comprises a concrete rod and a concrete rod base embedded in the ground. The concrete rod base comprises an outer sleeve and an inner sleeve. A concrete layer is disposed between the outer sleeve and the inner sleeve. The concrete rod is disposed in the inner sleeve. The underground gap between the concrete rod and the inner sleeve is a grading fine sand layer. The gap, above the ground, between the concrete rod and the inner sleeve is a fine aggregate concrete layer. Due to the fact that the concrete rod base comprises the inner sleeve and the outer sleeve, sludge collapse during base excavation can be prevented, original shape of concrete is maintained favorably, and anti-overturning moment of the concrete rod is increased. By a rubber damping ring added at the top of the inner sleeve, stress at the end of the concrete rod is reduced, windproof and shockproof capability of the concrete rod are improved greatly. In addition, the gap, above the ground, between the concrete rod and the inner sleeve is the fine aggregate concrete layer, when the concrete rod needs to be replaced, the concrete rod can be pulled out for replacement by excavating fine aggregate concrete mortar on the surface, so that further maintenance is facilitated.

Description

technical field [0001] The invention relates to a concrete pole, in particular to a windproof and reinforced concrete pole sleeve foundation. Background technique [0002] At present, the foundations of overhead power poles in the distribution network mainly include natural soil, chucks and large stone foundations, etc., which have poor anti-overturning ability. In the typhoon-prone coastal areas, during the typhoon season, the foundation of the concrete poles is loosened due to the rain washing the soil, and the accidents of the concrete poles tilting or falling often occur in the distribution network lines, threatening the safety of power supply. Therefore, it is very necessary to reinforce the area. The concrete pole foundation can improve the windproof ability of the line pole. However, because the soil quality in the coastal areas is mostly alluvial silt, the soil quality is poor, and the methods such as natural soil foundation and chuck used inland usually cannot prov...

Problems solved by technology

However, because the soil quality in the coastal area is mostly alluvial silt, the soil quality is poor, and the natural soil foundation and chuck methods usually used in the inland cannot provide sufficient anti-overturning moment for the concrete rod foundation.

[0003] In the past, in order to enhance the windproof ability of utility poles, windproof stay wires were often installed on concrete poles, but the installation of stay wires occupies a large area, such as hindering cultivation in the field, and hindering traffic in towns, so not all sites are equipped with installation stay wires condition
