Uru na ọghọm nke netwọk drainage mejupụtara

Netwọk mmiri mmiri mejupụtara bụ ihe a na-ejikarị arụ ọrụ okporo ụzọ, ebe a na-ekpofu ihe, mmepe mbara ala n'okpuru ala na ọrụ ndị ọzọ. Yabụ, kedu uru na ọghọm ya?

Uru dị mkpa nke netwọk mmiri mmiri mejupụtara

1, arụmọrụ drainage magburu onwe ya

Ngwugwu mmiri nke mejupụtara ya na-eji usoro nhazi atọ (ọkpụrụkpụ ya na-abụkarị 5-8 mm) , Ọgịrịga kwụ ọtọ dị n'etiti na-emepụta ọwa mmiri na-aga n'ihu yana nkwado dị elu, arụmọrụ mmiri mmiri ahụ dịkwa okpukpu ise ruo asatọ karịa nke oyi akwa gravel ọdịnala. Sistemụ mmezi oghere ya nwere ike iguzogide ibu dị elu (3000 kPa Ibu nrụgide) na-ejigide ike hydraulic kwụsiri ike, mgbanwe kwa oge nwere ike iru 0.3 m³/m² ， Ọ dabara nke ọma maka ọnọdụ ala pụrụ iche dịka mpaghara ala kpọnwụrụ akpọnwụ na ọgwụgwọ ntọala dị nro.

2, Ike dị elu na nguzogide mgbanwe

Ejiri polyethylene dị elu mee ya (HDPE) Isi mesh nke ejiri eriri polypropylene jikọta nwere ike ịdọkpụ ụzọ abụọ nke 20-50 kN/m, modulus nrụgide karịrị nke geogrid ọdịnala karịa ugboro atọ. N'ịtụle akụkụ okporo ụzọ dị arọ, nhazi nke subgrade etinyere na netwọk drainage composite na-ebelata site na 42%, a na-ebelatakwa ohere nke mgbawa okporo ụzọ site na 65%.

3, Nhazi agbakwunyere nke ọtụtụ ọrụ

Site na geotextile (200 g/m²Ụkpụrụ) na nhazi nke ihe mejupụtara nke isi ihe ntanetị atọ ahụ na-arụ ọrụ atọ nke "nkwado nzacha-mgbapụta-mgbapụta" n'otu oge:

(1) Nha nke ákwà elu nke na-abụghị nke a kpara akpa dị irè nke na-egbochi ihe dị n'ime ya ＞0.075mm.

(2) Isi ihe mesh ahụ na-ebupụ mmiri na-agafe agafe ngwa ngwa iji gbochie mmiri capillary ịrị elu

(3) Ọgịrịga siri ike na-eme ka ikike ibu ntọala dịkwuo mma ma belata mgbanwe dị n'okpuru ọkwa

4, Mgbanwe na ike imegharị gburugburu ebe obibi

Oke iguzogide acid na alkali nke ihe ahụ ruru pH 1-14, Na-70 ℃ Ruo 120 ℃ Oke okpomọkụ na-eme ka arụmọrụ kwụsie ike. Mgbe awa 5000 nke ule ịka nká UV gasịrị, ọnụego njigide ike ＞85%, Ndụ ọrụ nwere ike iru ihe karịrị afọ 50.

Mmachi ngwa nke netwọk mmiri mmiri mejupụtara

1, Enweghị ike ịgbapu ihe zuru oke

Ọkpụrụkpụ isi ntupu ahụ bụ 5-8 mm, A na-akụ ya ngwa ngwa n'elu ala nke nwere ajịrịja dị nkọ.

2, Ike nhicha mmiri dị oke elu

N'okpuru ọnọdụ mmiri na-agba ọsọ ọsọ (ọsọ ＞0.5m/s) , Maka ihe siri ike a kwụnyere (SS) Arụmọrụ mgbochi ahụ bụ naanị 30-40%, a kwesịkwara iji ya na tankị sedimentation ma ọ bụ akwa nzacha na ọrụ ọgwụgwọ nsị.

3, Iwu siri ike maka teknụzụ owuwu

(1) A ga-achịkwa ịdị larịị nke ala nke oghere dị n'okpuru ≤15mm/m

(2) Ihe achọrọ maka obosara ikpere 50-100 mm, Nabata akụrụngwa ịgbado ọkụ pụrụ iche

(3) Okpomọkụ gburugburu ga-adịrịrị -5 ℃ Ruo 40 ℃ N'etiti, oke ihu igwe nwere ike ibute mmebi ihe ngwa ngwa

4, Ọnụ ego itinye ego mbụ dị elu

Ma e jiri ya tụnyere oyi akwa ájá na ájá nkịtị, ọnụ ahịa ihe ahụ na-abawanye site na ihe dị ka 30%, mana ọnụ ahịa ndụ dum na-ebelata site na 40% (na-ebelata ugboro mmezi na ọnụego ndozi ntọala).

Ngwa injinia

1, Atụmatụ nhazi nke ụzọ obodo

N'ime usoro ụzọ asphalt, ịtọ netwọk mmiri mmiri mejupụtara n'etiti oyi akwa macadam a ma ama na obere ihe nwere ike ime ka ụzọ mmiri mmiri dị mkpụmkpụ ruo n'ọkpụrụkpụ nke oyi akwa ntọala ma melite arụmọrụ mmiri mmiri.

2, Sistemụ mgbochi mmiri mkpofu

Nabata "netwọk mmiri mmiri mejupụtara" + HDPE Impervious membrane "njikọta nhazi:

（1) Nduzi netwọk mmiri mmiri na-enye mmiri mmiri, ihe na-eme ka mmiri ghara ịbanye ≤1×10⁻⁴cm/s

(2) Akpụkpọ HDPE dị arọ 2mm na-enye nchebe mgbochi mmiri okpukpu abụọ

3, Ọrụ owuwu obodo ogbo

Ịtọ ihe dị n'ime akụkụ atọ n'ogige mmiri ozuzo na oghere akwụkwọ ndụ akwụkwọ ndụ gbawara agbawa, na-arụkọ ọrụ na PP. Ojiji nke ebe nchekwa modular nwere ike ibelata oke mmiri ozuzo site na 0.6 ruo 0.3 ma belata oke mmiri n'obodo ukwu.
