Description

  The present invention relates to weed control around a pillar body that combines the weed control and the greening to plan landscape greening with a short grass plant in order to control weeds around the pillar body such as guardrails and road signs installed on the road. Is.

  Weeds grow on the soil around pillars such as guardrails and utility poles installed on the road, the height of the plant becomes high, the prospects are poor, traffic safety is hindered, and the surrounding landscape is also adversely affected Therefore, weeding work is carried out every year at a huge expense. Moreover, in the weeding work around the pillars and poles such as poles and power poles, the blade of the mower hits the roots of the pillars and pillars and there is a risk of unexpected accidents. , Weeding work has been done over time and extra manpower.

Therefore, in recent years, a seal member impregnated with a herbicide is attached to a support column on the outer peripheral surface that becomes a boundary between the support column embedded in the soil and a groove portion that is fitted to the support column in advance so as to cover the periphery thereof. Weed control around props has been developed using a structure for preventing generation of useless plants around props (Patent Document 1) on which the formed concrete blocks are installed.

  However, the weed control method according to Patent Document 1 using the structure for preventing the generation of useless plants around the support pillars digs the soil around the support pillars to form a space where a concrete block can be installed, and the support pillars in this space part are impregnated with a herbicide. It is a method to suppress the weed growth around the support by installing a concrete block in which a groove is fitted to the support in advance so as to cover the surroundings with a tape, and a herbicide is added to the seal The impregnated herbicide may evaporate or be washed away by rainwater, etc. and the liquid herbicide is a fast-acting herbicide that permeates from the leaves and stems of weeds, but has a short duration and herbicide There is a risk that weeds will grow again due to buried seeds and flying seeds when the effectiveness of the agent is reduced.

  In addition, even if weed growth can be suppressed by the concrete blocks installed around the guard rail columns, there is a problem that weeds grow as usual around the lower part of the guard rail between the columns and the columns except the columns.
