Preparation device and method for double-compression high-strength raw soil bricks

Abstract

The invention discloses a preparation device for double-compression high-strength raw soil bricks. The preparation device comprises a fixing frame, a mold, an upper hydraulic device and a lower hydraulic device, the horizontally-arranged mold is arranged on the fixing frame in a sleeving mode, and the upper hydraulic device and the lower hydraulic device are arranged on the two sides of the mold correspondingly; the mold is provided with a brick making hole, a lower pressing piece is sleeved with the lower end of the brick making hole in a fit mode, and an upper pressing piece with a part being exposed outside the brick making hole is arranged in the brick making hole in a sleeved mode; raw soil is arranged in the position, corresponding to the position between the upper pressing piece andthe lower pressing piece, in the brick making hole in a clamped mode; and a piston rod of the upper hydraulic device is connected with an upper connecting plate which makes contact with the upper pressing piece and the top surface of the mold and is used for pushing the mold to move downward or pushing the upper pressing piece to enter the brick making hole, and a piston rod of the lower hydraulic device is connected with a lower connecting plate which makes contact with the bottom surface of the mold and is used for bearing the mold. Pressure is applied to the upper pressing piece through the upper hydraulic device, and the lower pressing piece serves as the bottom of the brick making hole, so that the raw soil is perpendicularly compressed, and the uniformity and the strength of the rawsoil bricks are increased. The invention further provides a preparation method for the double-compression high-strength raw soil bricks.

Description

technical field [0001] The invention relates to the field of civil engineering, and more specifically relates to a double-compression high-strength raw earth brick preparation device and a preparation method. Background technique [0002] Raw soil is a building material with a long history. It is composed of a mixture of soil and water. Raw soil is used to prepare raw soil bricks, and then the raw soil bricks are used to build walls, which is the construction method of raw soil buildings. Raw soil contributes to the health of occupants as it buffers changes in relative humidity and temperature within buildings, and also enhances occupant comfort. Moreover, the raw soil also has the advantages of environmental protection. The use of raw soil can reduce energy consumption during construction. Moreover, the raw soil comes from the soil and can also return to the soil, which is outstanding in sustainability. Based on the above advantages, the adobe architecture has gradually be...
