Technical Field

The utility model relates to a foundation structure, in particular to a hidden pipe salt discharge salt separation salt control foundation structure for saline-alkali soil improvement.

Background

The saline-alkali soil salt elimination is a measure for eliminating salt and water which are not beneficial to plant growth in the saline-alkali soil area, and has the effects of improving the saline-alkali soil and preventing secondary salinization of the soil. At present, drainage of saline-alkali soil comprises open ditch drainage, concealed pipe drainage, shaft drainage, biological drainage and the like. The drainage with the concealed pipe is a drainage technical measure for removing excess water in soil by using an underground ditch (pipe) under a certain soil layer depth of a saline-alkali soil. The excess water in the soil can be drained from the joints of the concealed pipes or the water filtering micropores of the pipe walls and seeped into the pipes, and the effects of controlling the underground water level, adjusting the soil water and improving the physical and chemical properties of the soil are achieved. The concealed pipe drainage has the advantages of being convenient for mechanical operation in the field, saving land and improving the land utilization rate. But the one-time investment is large, the construction technical requirement is high, and if the sand-proof filtering layer is not processed well, the blockage and the failure are easy to happen in the using process.

Detailed Description

As shown in fig. 1-2, a hidden pipe salt elimination salt separation salt control foundation structure for saline-alkali soil improvement comprises a sand-stone mixture layer 3 which is used for embedding a blind pipe 2 and is laid on a plain soil layer 1, wherein the upper part of the sand-stone mixture layer 3 is sequentially provided with a gravel layer 4, a geotextile 5, a planting soil layer 6 and a green planting layer 7 from bottom to top, the water in the planting soil layer 6 is drained away through the matching of the blind pipe 2 to realize salt elimination operation, the blind pipe is a pipe capable of permeating water of an outer wall into the pipe, compared with pipes such as a double-wall corrugated pipe and the like, the blind pipe 2 is low in cost, good in performance, high in cost performance and comprehensive in water seepage, and the slope of the blind pipe 2 is embedded by 0.2%.

The sand and stone material mixing layer 3 is laid in a base groove 8 used for gathering up the moisture on the upper part, and the two sides of the base groove 8 form a slope surface convenient for concentrating the moisture through slope releasing.

The section of the base groove 8 is of a trapezoidal structure.

Including blind pipe 2, the outer wall parcel of blind pipe 2 has the non-woven fabrics, and the non-woven fabrics can prevent and treat debris and block up the pipeline hole, is equivalent to the filter effect, and acid and alkali resistance is strong, and the practicality is strong, and is with low costs.

The thickness of the sand-stone mixture layer 3 is 20cm, the sand-stone mixture ratio is 1:1, and the particle size of stones is 2-4 cm.

The thickness of the crushed stone layer 4 is 15cm, and the particle size of the stones is 2-4 cm.

Geotechnological cloth 5 is laid for the bilayer, and soil layer 6 is planted in the bearing, separates upper portion and plants soil layer 6 and lower part drainage structures, prevents that the hack from infiltrating down, causes the jam, the filtering action of step one at first.

The blind pipe 2 includes the person in charge 21 and the branch pipe 22 of a big little pipe diameter, and the person in charge 21 is linked together through inspection shaft 9 with branch pipe 22 and forms the pipe network, and the person in charge 21 is the collector pipe, and branch pipe 22 is the pipe that absorbs water, and inspection shaft 9 mainly is used for checking whether normal work of saline and alkaline land improvement engineering system is used for washing the pipeline, and concrete layer can be pour to the bottom of inspection shaft 9 and interior well wall, forms the brickwork enclosure with fragment of brick shape cylinder all around.
