Abstract
The invention relates to a wind prevention and sand fixation system and method. A wind-shield wall is arranged on the sandy beach away from the coast by a certain distance; the wind-shield wall comprises a plurality of I steel columns and meshy plates, wherein the plurality of I steel columns are uniformly and vertically arranged on the sandy beach at intervals; a foundation is fixedly arranged on the lower end part of each I steel column and is positioned below the ground; a plurality of meshy plates which are connected together in sequence up and down are fixedly arranged between every two adjacent I steel columns; a sand fixation grid zone is arranged between the wind-shield wall and the coast; the sand fixation grid zone consists of a plurality of grids; the grids are arranged in two lines in a staggered manner; the left line of grids and the right line of grids are mutually connected to form a sand fixation zone. According to the wind prevention and sand fixation system and method, a plane for slowing the wind velocity down is formed near the wind-shield wall and the sand fixation grids in the system, so that the sand stop effect can be presented clearly along with different movement velocities in sand slip faces on both sides of the wind-shield wall and is finally sedimented on both sides of the wind-shield wall more evenly, and thus a formed sand stop dam has a remarkable wind prevention and sand fixation effect.
Description
Technical field
The invention belongs to the improvement field of seashore, desert, railway hazards of sand storms, especially one is checked winds and fixed drifting sand system and method.
Background technology
In China, inland and Desertification are quite serious by the impact of dust storm, directly have influence on the development of industrial and agricultural production and the physical and mental health of people.
At present, usually adopt the mode of installing sand-protecting barrier to prevent and control sandy storm, its principle reduces earth's surface wind speed, movable so as to weakening Sand Movement, three kinds of modes being common sand-protecting barrier and preventing and control sandy storm below:
One, adopt concrete stake to add cement components fence, this Fence structure is heavy, and be not easy transport and install, construction requirement is high, speed is slow, easily collides with, well damage.Fence space is large, and wind prevention and sand resistance less effective, easily forms sand dune.
Two, steel pipe post plastic-coated silk screen fence, this fence is under ultraviolet, saline and alkaline effect, and plastic coating is aging to come off, then steel wire corrosion, and application life is low, and 3-5 needs to reinstall substantially, and purposes is single, does not have the function such as wind prevention and sand resistance, resistance snow.
Three, use nylon mesh material to make fence, this nylon wire resistance sand fixes the sand facility, and there is following shortcoming: uviolresistance is poor, easily aging, damaged, application life is short; Fly away with the wind, degraded is slow, contaminated environment, feature of environmental protection extreme difference, and unsightly.To again lay every year, less economical; Not inherently environmentally friendly machine, produce in manufacturing process and pollute.
Patent document disclosed in finding following two sections through retrieval, concrete disclosure is as follows:
1, patent document: wind prevention and sand resistance barrier (notification number CN201305845), form primarily of tight Sand-fixation net, permeability of sand resistance section and energy dissipating ventilation section, permeability of sand resistance section passes through snap close, above be connected with energy dissipating ventilation section, lower with closely fix the sand plate and be connected, both sides are fixed on column, and diagonal all adopts nylon rope to connect, form the husky fence framework of fixing resistance, and reinforce at both sides miter angle nylon rope.
2, patent document: a kind of plastics lattice-valued automata (notification number CN204125929U) of wind prevention and sand resistance, this lattice-valued automata is square, its length of side L, expose Shamian Island height H, sand-protecting barrier permeability α, be respectively 0.5m≤L≤2m, 0.08m≤H≤0.5m and 1 × 10-10≤α≤1 × 10-8.
Find through contrast, above-mentioned two sections of documents and present patent application have relatively big difference in technical scheme.
