Method of using plain soil to produce hydraulic engineering seepage-proofing brick in situ

Abstract

The invention relates to the field of building materials and the field of water conservancy construction, in particular to various clay, weathered granite soil and hoggin soil. Soil at construction sites of artificial lakes, artificial canals and irrigation channels is used as main materials, special macromolecular coagulant, limestone or gravel sandy soil are mixed with Portland cement, and compression molding equipment is used for once forming of seepage-proofing bricks. The main materials include, by weight, 0.02 part of coagulant, 0.2 part of glass fiber chopped strands (biological straws), 70-80 parts of soil, 5-6 parts of cement and 10-15 parts of gravels (weathered granite soil). In terms of performance, the seepage-proofing bricks made by the method have sufficient compressive strength and shear resistance and can meet the normal artificial water conservancy seepage proofing requirements; in terms of process, operation is simple and easy and soil is taken in situ; and in terms of cost, the cost is at least 50% lower than that of cement mortar seepage proofing, soil needed to be removed at the construction sites is treated, construction cost is reduced, and construction cycle is shortened.

Description

technical field [0001] The invention relates to a method for preparing anti-seepage bricks, in particular to a method for making anti-seepage bricks for water conservancy projects on site by using plain soil. Background technique [0002] Currently used technologies, published patents or published documents generally make soil into non-burning bricks. Unlike the present invention, soil is generally mixed with cement and fly ash cementitious materials, and formed into non-burning bricks. Bricks, or mix soil with cement and powdery curing agent and then press them into unburned bricks, which are used in water conservancy anti-seepage projects for a long time , Poor shear resistance, poor antifreeze effect, and the product application range is not wide. [0003] The traditional anti-seepage method of lake canals generally uses cement and sand, which removes a large amount of waste soil, and the resulting transportation costs increase accordingly. At the same time, the amount o...

[0002] Currently used technologies, published patents or published documents generally make soil into non-burning bricks. Unlike the present invention, soil is generally mixed with cement and fly ash cementitious materials, and formed into non-burning bricks. Bricks, or mix soil with cement and powdery curing agent and then press them into unburned bricks, which are used in water conservancy anti-seepage projects for a long time , Poor shear resistance, poor antifreeze effect, and limited range of product applications

[0003] The traditional anti-seepage method of lake canals generally uses cement and sand, which removes a large amount of waste soil, and the resulting transportation costs increase accordingly. At the same time, the amount of cement required for the project is large, and the use of a large amount of cement is not good for environmental protection. The construction period is long, especially as the prices of raw materials and labor costs continue to rise, and with the continuous increase of water conservancy construction and artificial wetland construction projects, environmental protection and sustainable issues are becoming more and more obvious. Therefore, it is necessary to find an economical and environmentally friendly Rapid Construction Solutions
