適用于覆土深度大于1.5倍管外徑的條件下施工,人員無(wú)法進(jìn)入的小口徑頂管,長(zhǎng)距離頂管施工,各種粘土,N值小于50的砂土。
適用于靠近江、河、海、湖這些有水源的地方,地下水位高和地下水壓波動(dòng)比較大的條件下施工,適用于覆土深度大于1.5倍管外徑的條件下施工,人員無(wú)法進(jìn)入的小口徑頂管,長(zhǎng)距離頂管施工,各種粘土,N值小于50的砂土。
優(yōu)點(diǎn):施工速度快,施工精度高,挖掘面穩(wěn)定,地面沉降小,施工安全、可靠,施工作業(yè)環(huán)境好,集中控制減少施工作業(yè)人員。
It is suitable for construction near water sources such as rivers, lakes, seas and coasts, under conditions of high groundwater level and large fluctuations in groundwater pressure.
It is applicable where the overburden depth is more than 1.5 times the outer diameter of the pipe, for small?diameter pipe jacking where personnel cannot enter, and for long?distance pipe jacking.
It works in various clays and sandy soils with an N?value less than 50.
Advantages
Fast construction speed, high construction precision, stable excavation face, small ground settlement, safe and reliable construction, good working environment, and centralized control to reduce on?site operators.
