Description
Technical field
The present invention relates to desertification of land, desertification treatment technology, specifically is the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland.
Background technology
Desertification of land, desertification problem are one of environment, society, economic problems of the maximum that faces of the world today.The rapid spread of desertification of land, desertification has not only caused the deterioration and the serious economy loss of environment, even has also caused some regional social concerns, has hindered economic development and social stability.For example, in northwest China, distributing vast desert, desert and Gobi desert account for the sixth of Chinese area.Because natural causes such as the weather arid is short of rain add human unreasonable activities, cause desertification of land, desertification constantly to spread in this area, degenerate in flakes in the grassland, and a large amount of vegetation are swallowed up, thereby this area also is called " barren land " by people.The United Nations Conference on Environment and Development of holding in 1992 is summarised as climate change and mankind's activity with the factor of desertification of land, desertification; And finally being decided to be " World Day to combat desertification " on the June in every year 17; Be intended to further improve the understanding of people, arouse the sense of responsibility and the sense of urgency that people prevent and treat desertification of land, desertification control desertification of land, desertification importance.
The control soil is husky, the key of desertification is to fix the sand, and various desertifications of land for a long time, desertification treatment technology are just around fixing the sand to carry out.Existing desertification of land, desertification treatment technology mainly comprise biological treating and chemical harnessing.Biological treating is meant and relies on plantation vegetation (like trees, turf etc.) to carry out sand consolidation with biologic that this is also to be to promote the technology of improvement the most widely the earliest.Chemical harnessing is meant that then the surface sprinkling sand-consolidating agent carries out chemical sand-fixing on the sand dune.Practice shows, adopts existing desertification of land, desertification treatment technology to prevent and treat desertification of land, desertification, produces little effect.Particularly, the shortcoming of biological treating is: the vegetation of being planted is very easily blown away by dust storm or is buried by the sand dune, adds the desert area drought and water shortage, and vegetation can't survive too of a specified duration, causes sand-fixing effect unsatisfactory.And the shortcoming of chemical harnessing is: one of which because the sand-consolidating agent demand is very huge, causes treatment cost very high.Its two owing to limited by the desert area weather conditions, can't plant vegetation when carrying out chemical sand-fixing, thereby can't fundamentally administer desertification of land, desertification.Based on above analysis; Problem to having desertification of land now, desertification treatment technology sand-fixing effect is undesirable, with high costs and can't fundamentally administers desertification of land, desertification is necessary to invent a kind of brand-new desertification of land, desertification treatment technology.

The problem of the present invention in order to solve existing desertification of land, desertification treatment technology sand-fixing effect is undesirable, with high costs and can't fundamentally administers desertification of land, desertification provides a kind of sandy wasteland unconcerned polygon huge cement sanded brick.
The present invention adopts following technical scheme to realize: the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland comprises the brick body; The brick body is processed by following raw material: desert sand and cement; Wherein, desert weight ratio husky and cement is 1.5:1-5.58:1; The height of brick body is 1-8m; The widest part width of brick body is 0.5-3m.The shape of brick body is decided according to the actual requirements.
During concrete the use, the several bricks body uprightly is positioned over top of sand dune in turn, makes each brick body arrange and build up brick wall one through crane gear.The orientation of brick wall and desert wind are to vertical, and the leeward side at brick wall adopts desert sand to be piled into husky wall simultaneously, is used to support brick wall.Using such method, desert area uniformly-spaced (usually at interval 0.5km) build up the multiple tracks brick wall, and form the brick wall grid through the multiple tracks brick wall, the sand dune is formed latticed cutting apart.When dust storm passed through the brick wall grid, whenever through one brick wall, wind-force intensity will be successively decreased, and sand and dust density also decreases, and had not only played thus and had reduced the effect of desert dust storm, and fundamentally stoped flowing of sand dune, played the effect of effectively fixing the sand.On the basis of effectively fixing the sand, the plantation vegetation can guarantee that just vegetation has enough growth periods at the brick wall rear, makes vegetation be able to the large tracts of land survival with the formation oasis, thereby thoroughly contains spreading of desertification of land, desertification, improves existent environment of people.Based on said process, to compare with biological treating, the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland of the present invention can not blown away or buried by the sand dune because own wt is huge by dust storm.Thereby adopt the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland of the present invention that latticed cutting apart carried out on the sand dune, and the sand dune can't be moved in the brick wall grid, effectively improve sand-fixing effect.Simultaneously, produce sanded brick and brick wall itself and can spend a large amount of desert sand again, thereby reduce the sand amount in desert, further improve sand-fixing effect.Compare with chemical harnessing, the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland of the present invention need not to adopt sand-consolidating agent, and adopts with husky sand control, and simultaneously, sanded brick can be produced in the desert on the spot, and it is very convenient to construct.In sum, the problem that the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland of the present invention has promptly thoroughly solved existing desertification of land effectively, desertification treatment technology sand-fixing effect is undesirable, with high costs and can't fundamentally administer desertification of land, desertification.
The preparation method of the unconcerned polygon huge cement sanded brick in a kind of sandy wasteland of the present invention comprises the steps: a. preparation mortar: desert sand, cement, water are mixed, and stir the formation mortar; Desert weight ratio husky and cement is 1.5:1-5.58:1; The denseness of mortar is 20-100mm; B. molding: mfg. moulding die, and at mold cavity surfaces laying plastic sheeting; C. grouting: the mortar for preparing is poured into dies cavity; D. vibrate: the mortar to pouring into dies cavity carries out vibration compacting; E. maintenance: seal maintenance through the mortar of plastic sheeting after to vibration compacting, curing time is 10-20d; F. form removal: with mortar after the maintenance and mold separation, and the mortar after will separating carries out air dry, promptly obtains the brick body.
The problem that the present invention efficiently solves existing desertification of land, desertification treatment technology sand-fixing effect is undesirable, with high costs and can't fundamentally administer desertification of land, desertification; The various shortcomings that it has overcome biological treating and chemical harnessing existence are applicable to the improvement of desertification of land, desertification.
