The application discloses a preparation method of low-shrinkage low-heat low-carbon concrete, and has the technical characteristics that high-water-absorption autoclaved silicate functional aggregate is used to replace gravel and yellow sand, and the mass sum of fly ash and mineral powder in the cementing material can be up to 60% at most. The high-water-absorption water-saturated autoclaved silicate functional aggregate and the expanding agent are added into the concrete, the humidity is released through the functional aggregate, the internal curing and the expansion of the expanding agent are cooperated, the self-shrinkage, the drying shrinkage and the hydration heat shrinkage of the concrete are reduced, and the strength of the concrete is improved; the grading of the fine aggregate of the superfine yellow sand is improved through the addition of the fine functional aggregate, the working performance of the concrete is improved, and the low-carbon environmental protection of the concrete is realized through the large amount of mineral admixtures.

The municipal greening isolation fence comprises a base, a planting groove is formed in the base, a water storage cavity and a water supply channel are formed in the base, a water absorption strip is arranged on the base, a connecting pipe is arranged on the base, a through hole is formed in the connecting pipe, and an inserting opening is formed in the outer side wall, away from the connecting pipe, of the base; a water inlet is further formed in the base, and a plugging assembly is arranged on the base. During use, the connecting pipe on the base is inserted into the inserting opening in the adjacent base, then the inserting opening in the base at the head end is plugged, water is injected into the water inlet in the base at the tail end, meanwhile, the through hole in the water injection base is plugged by hands, and water can flow into the water storage cavity in the adjacent base; water in the water storage cavity can be transferred into the planting grooves through the water absorption strips to supplement water to the potted plants in the planting grooves, and workers do not need to move in the arrangement direction of the municipal greening isolation fence, so that water supplementation to the potted plants on the greening isolation fence is more convenient and faster.
