（1）滾塑一次成型，可制造二通、三通、四通90°~165°任意交匯的所有規(guī)格檢查井。
（2）充分體現(xiàn)滾塑制品的優(yōu)越性：耐沖擊，耐擠壓，耐磨，抗應(yīng)力開(kāi)裂性好，耐化學(xué)腐蝕性好，耐老化，使用壽命長(zhǎng)。
（3）水流阻力小，提高排放效率。
（4）搬運(yùn)很方便，提高施工效率。
（5）整體一次成型，極無(wú)滲漏，沒(méi)有二次污染。
（6）塑料檢查井配井內(nèi)蓋和安全網(wǎng)，當(dāng)井蓋破裂或被盜后能有效防止人、車安全。
（7）可回收循環(huán)利用。

(1) rotomolding a forming, can make two-way, tee, four-way 90 ° ~ 165 ° any intersection check well all the specifications.
