竖井凿井期间的吊桶的提升能力,是影响施工速度的一项重要因素。为了使提升能力适应快速施工,一方面是需要提高吊桶的提升速度,同时也要在有限的井筒断面内,尽量布置容积较大和数量较多的吊桶,这可以用单位净断面的吊桶容积q(q=通过该断面的提升钩头所悬吊吊桶容积的总和/井筒净断面面积,米~3/米~2)来表示,通常使q=0.1～0.15。但深井施工中,由于提升能力随着井深增加而减小,如井深1000米,q=0.20米~3/米~2,提升机绳速V=5～6米/秒,这样,如按照一般施工工艺安排来计算,其平均月成井速度的极限也仅是70米左右,若要提高
The lifting capacity of buckets during shaft sinking is an important factor affecting the construction speed. In order to adapt to the rapid construction of lifting capacity, on the one hand, it is necessary to improve the lifting speed of the bucket, and at the same time, it is necessary to arrange the bucket with larger volume and larger quantity within the limited wellbore section, which can be expressed as q q = the total bucket volume suspended by the lifting hook head of the cross section / the net section area of the wellbore, m ~ 3 / m ~ 2), usually q = 0.1-0.15. However, in deep well construction, the hoisting rope speed V = 5 ~ 6 m / s, as the ascension ability decreases with the increase of well depth, for example, the well depth is 1000m and q = 0.20m ~ 3 / m ~ Construction technology to calculate, the average monthly rate of completion of the shaft is only about 70 meters, to improve
