As shown in Figure 1 to 11, adopt above-mentioned chemical sand-fixing materials application process to carry out chemical sand-fixing materials to certain moving dunes and use, its concrete steps are as follows:
(1) determine to select fluid oral pore footpath to be the nozzle 1 of 0.2mm according to the geological conditions of these moving dunes and sandy situation; Arrange according to implementing the matrix of density determination nozzle 1 in 4X3 bottom separatory dish 2, and the spacing of adjacent two nozzles 1 is 10cm; According to said structure by each assembling parts of chemical sand-fixing materials application device together, and by the mass concentration prepared be 10% chemical sand-fixing materials be encased in liquid reserve tank 4, what then drag that the chemical sand-fixing materials application device assembled moves to these moving dunes by bearing truck 7 uses place.
(2) opened by the sealing-plug of the air vent 22 of separatory dish 2, force (forcing) pump 5 pressurization makes chemical sand-fixing materials enter in separatory dish 2, until when chemical sand-fixing materials is full of separatory dish 2, seals the air vent 22 of separatory dish 2 with sealing-plug.
(3) determine that the bottom of nozzle 1 just contacts with sandy land surface according to the landform situation using place of these moving dunes; The spacing of separatory dish 2 and sandy land surface is adjusted, until nozzle 1 bottom just contacts with sandy land surface by action bars 6.
(4) adjusting the pressure in liquid reserve tank 4 by the pressure control valve 52 of force (forcing) pump 5 is 20kpa, chemical sand-fixing materials in liquid reserve tank 4 flow in separatory dish 2 by woven hose 3 under pressure, and uniform divided flows is to each nozzle 1, and being injected on sand ground by nozzle 1, the chemical sand-fixing materials amount of application of each decanting point is 1mL.
(5) push up toe from this moving dunes slope, adopt this chemical sand-fixing materials application device to fix a point to implement to inject, until these moving dunes have injected every 10cm.
(6) after these moving dunes have injected, under not carrying out artificial disturbance situation, make natural drying 1 ~ 2 day, using the chemical sand-fixing materials of these moving dunes can be completed.
After testing: the surrounding of each decanting point is not all because the infiltration spread of chemical sand-fixing materials defines the hard induration of round pie that radius is 5cm, and cemented together between these indurations; Get a little tap water and carry out simulated precipitation spray test, find that precipitation infiltrates rapidly on the sandy soil top layer of these moving dunes and to retain without ponding; The plant species word bank observing these moving dunes at Growing season sprouts situation, finds that seed is obviously sprouted.
As fully visible, the present invention can not only promote sand-fixing effect, improve sand-consolidating agent effective rate of utilization, reduce sand-consolidating agent amount of application, and can effectively avoid forming waterproof bonding course on sand bed surface, reduce the harmful effect to soil infiltration capability, decrease the resistance to seed germination, thus significantly can improve the regeneration rate of desertification.
The above; be only the present invention's preferably detailed description of the invention, but protection scope of the present invention is not limited thereto, is anyly familiar with those skilled in the art in the technical scope that the present invention discloses; the change that can expect easily or replacement, all should be encompassed within protection scope of the present invention.Therefore, protection scope of the present invention should be as the criterion with the protection domain of claims.
