On October 25, wear consolidate of tall spurt of region of B of the bottom of a well of shaft of south bank of hole of Sui of line of yellow project upper reaches to complete construction of picket of last tall gush, construction of this area consolidate is finished entirely.
Wearing shaft of yellow project south bank is the working well that after aegis compose machine has completed construction of reach Sui hole, undertakes overhaul of aegis compose machine is used. Go up, configuration of shaft of hole of downstream line Sui is identical, shaft internal diameter 13.4 meters, periphery all uses form of subterranean diaphragm wall, liner uses structure of 80 centimeter thick ferroconcrete. Shaft bottom uses the consolidate method of high-pressured gush coming back, main effect is after preventing excavate of hole of radical of exceeding operational depth, be in base side of hole inside and outside forms natural environment pressure to differ and bring about apophysis of system of the land inside shaft to be out of shape, destroy to what structural products is born. Two area have area of A of cent of back cover consolidate and B area in installment construction, after finishing subterranean diaphragm wall above all, double high pressure is used to be in charge of a law to undertake consolidate construction to A area threefold in the ground; B area consolidate is waited for sheet is used to be in charge of a law to undertake consolidate construction after finishing the 8th liner. B area consolidate decorates picket of consolidate of 960 tall gush in all, every picket diameter 500 millimeter, between picket and picket build effectively receive 100 millimeter, the platoon is apart from 345 millimeter, apply man-hour to get hole depth to spend 21 meters, consolidate deepness 6 meters. After B area consolidate is finished, add solid to join with area of A of early days consolidate, form the whole end a solid hole.
Next, shaft of south bank of hole of upriver line Sui construction of liner of proceed the rest.
