Description

A kind of soil sanitation bed fillers

Technical field

Technical field of sewage is the utility model is related to, especially a kind of soil sanitation bed for preventing draining blockage Filler.

Technical background

Waste water soil treatment refers to utilize ecological engineering principle, and by sewage, controlledly dosing to soil-plant system, is led to The comprehensive function crossed under the natural conditions such as physics, chemistry and biology, except the nutritional ingredient and pollutant in decontaminated water, reach place Reason and using sewage and provide regeneration water source purpose.As the improvement of people's living standards, the pollution species in sanitary sewage Class and content are also increasingly abundanter, and the simple soil sanitation sewage relied under native state has been difficult the requirement for meeting people, Various fillers are added on the basis of natural soil can improve the hydraulic load and capacity of resisting impact load of soil sanitation bed.

Soil sanitation bed can choose one to multiple kind of filler according to the property and design object of original position soil, and Huang controls equality design Soil sanitation bed system, referring to：A kind of domestic sewage in rural areas soil sanitation bed system of adjustable water level, application number 201620863156.7, Authorization Notice No. CN 205892880 U, in the original location native lower section add respectively haydite, ventilative coarse sand and Crushed rock filler, there is good removal effect to the organic matter in sewage and nitrogen and phosphorus pollutantses, while come using pipeline collection system Reach the purpose of regulation water level.Because undisturbed soil soil particle is smaller, the silt being mixed to form with sewage can cause sewage collecting Line clogging, not only influences sewage collecting and discharge, sewage caused by blocking and sedimentation can also increase pipeline it is impaired can Energy, reduce the service life of soil sanitation bed, and sewage collecting pipeline is buried below soil, and maintenance maintenance will spend huge Big manpower and materials, so needing to carry out pipe protection work when soil sanitation bed is built, avoid that line clogging occurs Situation.

The content of the invention

The purpose of this utility model is in view of the above-mentioned problems, structure one kind can prevent line clogging to have ventilative water permeability again The soil sanitation bed fillers construction method of energy, the soil sanitation bed increase by one layer of permeable geotechnique between sewage conduct and filler Cloth, the performance of its earth-retaining draining can greatly extend the service life of soil sanitation bed.

The technical solution of the utility model：

A kind of soil sanitation bed fillers construction method, including with nylon wire wrap up the metalling of water distribution guard system, metalling, Haydite layer, coarse sands layer, original state soil layer, with nylon wire parcel catchment guard system metalling and permeable geotextiles.Water distribution guard system Top is positioned horizontally in, collector pipe system level is located at bottom, and water distribution guard system and collector pipe system pipeline, which are used, is equipped with thick 20cm The nylon wire parcel protection that the aperture of rubble is 1mm × 1mm, the packed layer between water distribution guard system and collector pipe system pipeline are set Have four layers of filler, wherein bottom filler be 15-25cm thickness rubble, two layers reciprocal be that 15-25cm thickness rough sand is breathed freely filler coarse sand Layer, the haydite layer that three layers reciprocal are 15-25cm thickness, upper strata cover the thick soil layers in situ of 20cm, covered again above water distribution guard system Soil layer in situ thick 25-35cm, each thick permeable geotextiles of one layer of 1-3mm of covering above water distributor upper and lower and collector pipe, will Water pipe is separated with in-situ soil.

Described geotextiles use the anti-filter geotextiles with water permeability.

The course of work of the present utility model：

Sewage by pretreatment enters packing area by water distributor, and soil is utilized under hollow billet infiltration and soil filtration effect Physics, chemistry and the edaphon purification function of earth, crop absorb and form biomembrane by artificial dielectric and make The materials such as organic matter, nitrogen, phosphorus in sanitary sewage are able to trans-utilization, and sewage after treatment is arranged by the guard system that catchments Go out.

The advantages of the utility model and good effect are：

The utility model is simple in construction, cost is cheap, ventilative leakproof, water conservation soil conservation, effectively can prevent sewage conduct from blocking, It substantially prolongs the service life of soil sanitation bed.

Brief description of the drawings

Fig. 1 is the clean-up bed filling-material structure schematic diagram of the utility model structure.

In figure：1st, nylon wire wraps up metalling (irregular shape, the D=20-30mm, with 1mm*1mm holes for the guard system that catchments Nylon wire wraps up the guard system that catchments)；2nd, metalling (irregular shape, D=20-30mm；15cm-25cm)；3rd, coarse sands layer (15cm-25cm)；4th, haydite layer (15cm-25cm)；5th, soil layer in situ thick 20cm；6th, water distribution guard system is wrapped up with nylon wire Metalling (irregular shape, D=20-30mm, water distribution guard system is wrapped up with 1mm*1mm holes nylon wire)；7th, permeable geotextiles；8、 Soil layer in situ thick 25cm-35cm.

Embodiment

Embodiment：

The utility model soil sanitation bed fillers structure with nylon wire as shown in figure 1, including wrapping up the broken of guard system that catchment Rock layers 1, metalling 2, haydite layer 4, coarse sands layer 3, original state soil layer, wrap up with nylon wire the metalling 6 of water distribution guard system and permeable Geotextiles 7, water distributor system level are located at top, and collector pipe system level is located at bottom, water distribution guard system and the guard system that catchments The hole nylon wire parcel protection that pipeline is 1mm × 1mm with the aperture equipped with thick 20cm rubbles, water distribution guard system and the piping that catchments Packed layer between road under the overall leadership is provided with four layers of filler, wherein bottom filler be 15-25cm thickness metalling 2, two layers reciprocal be 15- The ventilative filler coarse sands layer 3 of 25cm thickness rough sand, the haydite layer 4 that three layers reciprocal are 15-25cm thickness, the in-situ soil of upper strata covering 20cm thickness Layer 5, the thick soil layers in situ 8 of 25-35cm are covered above water distribution guard system again, are respectively covered above water distributor upper and lower and collector pipe The thick permeable geotextiles 7 of one layer of 1-3mm, water pipe and in-situ soil are separated, and geotextiles use the anti-filter soil with water permeability Work cloth.

Sewage enters packing layer by water distributor, in the presence of hydraulic pressure and gravity successively by soil layer in situ 5 thick 20cm, Haydite layer 4, coarse sands layer 3 and metalling 2, finally collected and discharged by collector pipe.Anti-filter geotextiles and nylon wire parcel have ventilative Water permeability, while there is good mechanical strength and excellent elasticity, sufficiently thick packing layer can be supported, and can have Prevent sewage conduct from being blocked because of silt to effect；Anti-filter geotextiles have excellent puncture resistant ability, can resist most of plant roots System, damaged so as to ensure that water distributor will not be wound by root system of plant.

The crops such as rape, vegetables are planted in soil sanitation bed topsoil by peasant household, enter the mistake of packing layer in sewage Cheng Zhong, because the speed that filtering is blended under different zones is different, differential settlement can make geotextiles 7 and nylon wire wrap up and produce not With the deformation of degree, the concavo-convex of formation adds up also cause damage to sewage conduct for a long time, so in laying geotextiles 7 and Buddhist nun It should be noted to keep packing layer smooth when dragon net parcel, avoid the formation of big bumps.

Based on the present embodiment, those of ordinary skill in the art are obtained all under the premise of creative work is not made Other embodiment, belong to the scope of this patent protection.
