Abstract

The invention discloses production method and application of a straw core mould in civil engineering, belongs to the technical field of civil engineering, and relates to a new technology for using straws in civil engineering. The straws are taken as filling materials for filling a pre-designed mesh cage, can be used as a part of a wall, and can also be taken as the core mould to be poured into concrete or reinforced concrete to replace a traditional core mould. According to the production method and application of the straw core mould in civil engineering, disclosed by the invention, the moulddoes not need to be removed to be taken out, so that man-hour and manpower used in mold removal are reduced, and the construction period is greatly shortened; the production method can be widely applied to civil engineering, the construction is convenient, and no professional equipment and professional trained operators are needed; a large quantity of plant straws are used, and pressed film moulding is performed without using chemical raw materials, so that the pollution to the environment is reduced, the problem of rural straw recovery is solved while the cost is low, and the production method is suitable for widespread promotion and use. The production method disclosed by the invention is extremely beneficial to environmental protection, and has remarkable economic and social benefit.

Description

technical field

[0001] The invention relates to the technical field of civil engineering, in particular to a production method and application of a straw mandrel in civil engineering. Background technique

[0002] When plant straw is used in engineering, the plant straw is usually crushed and mixed with chemical raw materials as part of the filling material, and then formed into a plate or block material by pressing film. The disadvantages are that the amount of straw is small, the technical process is complicated, the chemical raw materials used are not conducive to environmental protection, the product quality is unstable, and it is not conducive to large-scale promotion and use.

[0003] Therefore, there is an urgent need for a novel technical solution in the prior art to solve this problem. Contents of the invention

[0004] The purpose of the present invention is to provide a method and application of a straw mandrel manufacturing method in civil engineering. By fill...

Embodiment Construction

[0018] The technical solutions in the embodiments of the present invention will be clearly and completely described below. Obviously, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0019] The manufacturing method of the straw mandrel in civil engineering includes the following steps, and the following steps are carried out in sequence,

[0020] Step 1, drying the straw until the bulk density is less than 55Kg / m3;

[0021] Step 2, making a mesh cage, the bottom of the mesh cage is sealed, the upper part is open, the length of the mesh cage is 1.2m to 1.5m, the cross section of the mesh cage can be any geometric shape, and the mesh cage can be spliced ​​and combined along the length direction Splicing and combi...
