In order to control the desert, increase the employment, protect the environment and mankind, policy and fund supports from the government are expected by enforcers. Whoever using the invention is forbidden obtaining sands by destroying the green land, hills and riverbeds.

Description

The molten sand of a kind of usefulness is the method that stone is administered the desert

Technical field:

The invention belongs to the what field of environment protection.Being a kind of comprehensive method of inventing in order to administer the desert, is a kind of of sand industry.

Background technology:

The continuous expansion in desertification of land and desert gives China also to the harm of bringing on a disaster property of the world.Ancient civilization was buried in 10000000 year; Swallowed up in forest, grassland; The river, lake is blotted; Urban and rural residents suffer the harm of sandstorm; And active sand dune threaten to urban and rural residents, cultural historic site, tourist attractions, traffic main artery, critical facility etc. especially; Terrestrial climate also quickens and the disaster increase because of the expansion in desert heats up ...

Mr. Qian Xuesen once foretold: taking over the 6th Industrial Revolution of information industry revolution, will be the knowledge agriculture that comprises " sand industry ".Qian Xuesen is pointed out again: " ' sand industry ' be with system thinking, organic conception, scientific and technological achievement, industry chain (supply chain), the market promotion, culture to fetching operation control, realize the eucyclic novel industry of ' enlarge afforested area in the desert, peasants and herdsmen increase income, enterprise's synergy ' ".Money has a long-cherished wish always: " finished this revolution with 100 year time, just begin now, desert area can be created the output value that exceeds 100 billion." at present " sand industry " of China at the early-stage, obtained very big achievement.

Existing method of administering the desert has a variety of, comprises plantation psammophyte, covering, reaches some biochemical measures etc., does not exemplify one by one.The present invention uses the sand in desert in a large number, cooperates the method for my another patent application, can play and eliminate sand dune one by one step by step up hill and dale, and turn waste into wealth, comprehensive utilization, the formation industry creates more jobs, gradually reduce governmental investment, the change desert is oasis, also makes contributions for slowing down climate warming.The invention of wishing me can make the old wisdom of the money century-old long-cherished wish of making peace in advance realize early.

Summary of the invention:

According to Beijing Evening News on July 2 calendar year 2001: State Economic and Trade Commission's requirement, 170 big and medium-sized cities were realized before 30 days June in 2003 banning use of and are destroyed arable land, contaminate environment, solid clay brick that quality is lower, and other provincial capitals will reach this requirement in the end of the year 2005 at the latest.Also report: statistical figure show that China fires 7,000 hundred million of solid clay bricks (also having data to say so 8,000 hundred million) every year altogether, and 14 billion cubic meters that fetch earth are equivalent to ruin 1,200,000 mu in field, also will consume the energy of 6,000 ten thousand tons of standard coals simultaneously.

But this so far clay brick, is found everywhere in the suburb even Beijing, capital is no exception at least everywhere also all in usefulness.Have now a kind ofly non-burning brickly can solve a part of building brick, but also can't resolve whole promoting energetically.Economic developing rapidly, people's inhabitation require also developing rapidly, thus clay brick forbid still need to look for substitute products and popularized.

The present invention be use long-pending sand in the desert to found into building brick, paving brick in a large number, exempt to build the vallum brick, artwork and other stoneware.Sand dune or long-pending sand are destroyed one by one blocks ofly, can build the husky wall of resistance to the active sand dune that are difficult for eliminating at once, it advances in order to temporary transient prevention, waits until in the future to solve again.

The stove of molten sand can adopt glass-melting furnace commonly used at present earlier, and the available energy comprises Sweet natural gas, coal gas, coal, oil, electricity etc.According to founding the sand in desert and the characteristics of practical application, design smelting furnace more energy-conservation, that more reduce cost then.The sand of the general fusion cast glass of husky different whats in desert waters technology, prescription and tool and mould that cast stone brick, stone artwork and other stoneware also have different what system glass.Therefore in order further to improve output, to reduce cost, also need set up special intermediate experiment base, the project of success of the test is in time promoted.

The building stone brick of founding is owing to more solid than common brick, so the energy-conservation brick of the hollow insulating that can be designed to differ in size.And owing to be to take the method for casting, so can also design the special-shaped stone brick of various uses.Construction industry is more taken a step forward.

The paving brick of founding can be divided into plain floor tile and administer " the water conservation greening paving brick " that the desert is used, and key is " water conservation greening paving brick ".It is the square block of interior empty 1/4th garden interior angles that its structure is one jiao, when four bricks are abandoned, but the hole, garden of a kind of plant of intermediate formation.The size design in hole should be with reference to the annual rainfall of locality and the kind of plan institute kind of plant.Its effect is mainly and reduces water evaporates and ensure plant-growth.

" the exempting to build the vallum brick " of founding is mainly with what stopping active sand dune.Its structure has convex-concave locating point or groove, the flat brick of weight about 20 kilograms for each design up and down.Direct dislocation type was up and down built and is got final product when it used, without cement or other caking agent, but highly not beneficial too high, generally can be at 1.5 meters to 2 meters high, single or double row all can, double person is fit to the fast sand dune of flowing, its that row that facings the wind can be perpendicular to the ground, and leeward that row can fill out part sand to windward side inclination certain angle in the middle of two rows, wall also can high point, and the husky wall of such resistance approximately can stop the sand dune to be advanced to reach about a century.

Make the industry of stone artwork or other stoneware with molten husky the casting, both can increase elimination, thereby can reduce exploitation protection mountain forest again massif stone to the desert sand.Fast because of its production rate, can also improve output, the reduction of product and chisel and carve cost, and, can also develop more style by changing prescription, color and production technique.

Embodiment:

1, selecting one earlier has the unit of glass-melting furnace to cooperate (newly-built one also passable, the first stage of investment comprises about 1,000,000 yuan of factory building, about 20 tons of smelting furnaces, auxiliary facility, start up expense etc.).

2, select two batches of sands of thickness to carry out the initial stage experiment from the desert region, to determine several product styles and base cost of manufacture.It is helpful that this works out corresponding policy to central authorities or local government.

Can addressing when 3, applying nearer but place with good conditionsi (I promise to undertake this individual medium and small factory in area is exempted from patent royalties) also can promote (such as stagnant medium and small glasswork or second-hand brick factory etc.) in other regional places with good conditionsi on the distance sand dune.If combine with the mode of transport in my another patent, then can also reduce transportation cost greatly.

4, get Sha Shiying in the sand dune and note 2 points, the one, if when soil layer is very thin under the sand dune, must not destroy soil layer, would rather keep one deck sand, to afforest then.The 2nd, the area few to rainfall amount, after eliminated on the sand dune, available water conservation greening paving brick big area floor file water conservation was also afforested.Administer the desert crux and still will afforest, plant has only been arranged, insect just can be arranged, birds are arranged, animal is arranged, could form biologic chain.

5, for the active sand dune of temporary transient unable elimination, can produce and exempt to build the vallum brick in a large number, construct resistance husky Great Wall (length is as required) then in the windward side of active sand dune.According to scientist research, moving of sand dune mainly is the result that the grains of sand roll forward under wind action, and comprises most sands of coarse sand grain, the middle grains of sand, in that it is showy highly all below 10 centimetres the blowing of wind under.Therefore hindering husky wall builds 1.5 meters to the 2 meters high reaches that promptly are enough to block the sand dune.After waiting until the certain period,, and also do not have the way on more effective elimination sand dune at that time, can build the husky wall of a resistance again in the windward side if wall foreset sand is crossed the husky wall of resistance soon.Be no matter how high the sand dune is long in a word, allow the sand dune readvance never.The anti-rules of treatment for fine sand dirt need other measure.

6, for certain rainfall amount is arranged, the sand dune of certain humidity can be arranged below the sand promptly, hindering husky wall can be used in combination with " water conservation greening paving brick ", and psammophyte is better grown up.Also just can stop the sand dune reach better.

7, suggestion country afforests paving brick to found into water conservation with the sand in desert, the act of exempting to build vallum brick and building brick should give encouragement and support in some way.Advise also that simultaneously need not exempt to build the vallum brick builds a house.
