Kushandiswa kwenetwork yekudhonza mvura ine mativi matatu munzvimbo dzinosangana nzira yekuzadza nekucheka

Mukuvaka migwagwa mikuru, nzvimbo yemugwagwa inochekwa-chekwa inobatanidza zvisina kusimba muchimiro chenzvimbo yemugwagwa, zvichikonzera kusagadzikana kwekugara, kuputika kwemigwagwa nezvimwe zvirwere zvinokonzerwa nekupinzwa kwemvura pasi pevhu, kusiyana kwezvinhu zvinozadzwa nekuchera uye tekinoroji yekuvaka isina kunaka. Network yemvura inosanganiswa nemativi matatu inyaya inowanzoshandiswa kugadzirisa matambudziko aya. Saka, ndeapi mashandisirwo ayo munzvimbo yemugwagwa inochekwa-chekwa?

1. Zvinokonzera zvirwere uye zvinodiwa pakubuda kwemvura mumugwagwa wepakati penzira

Zvirwere zvemumugwagwa we cut-fill junction zvinonyanya kubva mukupesana kunotevera:

1. Kusiyana kwekupinda kwemvura pasi pevhu uye zvinhu

Kubatana kwenzvimbo yekuzadza nenzvimbo yekuchera kunowanzoita kuti pave ne hydraulic gradient nekuda kwemusiyano wehuwandu hwemvura yepasi pevhu, zvichikonzera kupfava kana kukwesha kuzadza.

2. Zvikanganiso zvekuvaka

Muzviitiko zvechinyakare, matambudziko akadai sekuchera nhanho dzisina kurongeka uye kusakwana kwekumanikidzana panzvimbo dzakachekwa zvakajairika.

2. Mabhenefiti ehunyanzvi emhando nhatu dzemvura inosanganiswa

1. Kushanda zvakanaka kwemvura uye kudzivirira kusefa

Mambure ekudhonza mvura ane mativi matatu akagadzirwa negeotextile ine mativi maviri uye core yepakati ine mativi matatu. Ukobvu hwe core ye mesh i5-7.6mm, porosity i>90%, uye kugona kwe drainage i1.2×10⁻³m²/s, iyo yakaenzana ne 1m gobvu gravel layer. Nzira yekudhonza mvura inoumbwa nembabvu dzayo dzakamira uye mbabvu dzakatsveyama inogona kuchengetedza kufambisa mvura kwakasimba pasi pemutoro wakawanda (3000kPa).

2. Simba rekusimba uye kusimbisa hwaro

Simba rekudhonza remambure emvura ane mativi matatu rinogona kusvika 50-120kN/m, izvo zvinogona kutsiva basa rekusimbisa mamwe mageogrids. Kana rakaiswa panosangana kuzadza nekuchera, chimiro chayo chepakati pemambure chinogona kuparadzira huwandu hwekushushikana uye kuderedza kusiyana kwenzvimbo.

3. Kugara kwenguva refu uye nyore kuvaka

Yakagadzirwa ne polyethylene (HDPE) ine density yakakura uye polyester fiber composite, iyo inodzivirira mwaranzi ye ultraviolet, acid uye alkali corrosion, uye ine hupenyu hwekushanda hwemakore anopfuura makumi mashanu. Hunhu hwayo hwakareruka (huremu pachikamu chimwe nechimwe <1.5kg/m²) hunoita kuti zvive nyore kuisa nemaoko kana nemagetsi, uye kushanda zvakanaka kwekuvaka kwakakwira ne40% kupfuura kwematombo echinyakare ematombo.

III. Nzvimbo dzekuvaka uye kudzorwa kwemhando

1. Kurapa kwepasi pevhu

Upamhi hwechikuva chedanho panoungana kuzadza nekuchera i ≥1m, kudzika kwacho kuri pavhu rakasimba, uye kukanganisa kwenzvimbo yacho ku ≤15mm. Bvisa zvinhu zvakapinza kuti usaboore mambure ekudhonza mvura.

2. Maitiro ekuisa

(1) Mambure ekudhonza mvura akaiswa padivi pemugwagwa, uye gwara guru remagetsi rakanangana nedanho;

(2) Kupindirana kwacho kunogadziriswa nekushandisa hot melt welding kana kuti zvipikiri zvakaita seU, zvine daro re ≤1m;

(3) Saizi yepamusoro yezvikamu zvemusana i ≤6cm, uye michina yakareruka inoshandiswa kuomesa simbi kudzivirira kukuvadza mesh core.

3. Kuongororwa kwemhando yepamusoro

Mushure mekuiswa, bvunzo yekufambisa mvura (yakajairika ≥1×10⁻³m²/s) uye bvunzo yesimba rinopindirana (simba rekudhonza ≥80% yehukuru hwedhizaini) zvinofanirwa kuitwa.

Sezvatinoona kubva pane zviri pamusoro apa, network yemvura inoyerera ine mativi matatu inogona kuvandudza kugadzikana uye kugara kwenguva refu kwenzira yekuchera mvura kuburikidza nemabhenefiti ayo ekubvisa mvura zvakanaka, kusimbisa simba remagetsi uye kugara kwenguva refu.
