Abstract

The invention discloses an assembly-type enclosure wall and a preparation method thereof. The enclosure wall comprises cup foundations, a ground beam, an enclosure wall plate, a coping, wind-resisting columns, and column caps, wherein the enclosure wall plate, coping, and column caps are prepared by casting fluid ultrahigh performance inorganic powder concrete, and the fluid ultrahigh performance inorganic powder concrete is composed of the following components in parts by weight: 500 to 650 parts of low-alkaline silicate cement or ordinary silicate cement, 85 to 120 parts of silica fume, 115 to 145 parts of II-grade fly ash, 175 to 215 parts of mineral slag powder, 1050 to 1250 parts of river sand, 26 to 32 parts of high efficient water reducer, 130 to 145 parts of water, and 100 to 140 parts of straight copper-coated steel fiber. The enclosure wall has the advantages of beautiful appearance, high anti-compression and anti-breaking strength, and light weight; and the weight of the assembly-type enclosure wall is one third to one fifth of the weight of ordinary concrete masonry trench or concrete poured trench.

Description

technical field [0001] The invention relates to enclosure walls in substation engineering, in particular to an assembled enclosure wall and a preparation method thereof. Background technique [0002] With the tight construction period and high quality requirements of modern construction projects, in construction projects, especially in substation projects, the construction of enclosure walls is increasingly required to have a short construction period but good construction effects. Most of the wall construction in the prior art adopts masonry walls, that is, bricklayers use cement wall bricks and other materials to build the required walls. This kind of walls has short service life, high maintenance costs, unsightly appearance, and long construction period. [0003] The Chinese patent "A Low-Cost Active Powder Concrete and Its Preparation Method" with application number 200910060802.0 discloses an active powder concrete with a mass ratio of 0.52~0.58:0.16~0.18:0.10~0.16:0.13...
