Step A carries out the construction of active well (9) and received well (10) according to construction requirement；
Step B installs power station (1), mud pumping plant, host (4) and laser transit (2) respectively, then carries out multi-direction solid
It is fixed, and power on carry out test-run a machine；
Step C sets up gantry hanging (18) above active well (9), is used for guide head (14), guide rod (20), first row
The lifting and movement of mud pipe (25), three-in-one compound tube；
Step D successively installs guide head (14) and guide rod (20), is oriented to according to cursor and carries out guide digging, according to computer
The centre deviation observed in monitor adjusts the rotation angle of power head device in real time and then adjusts inclined guide surface (142)
Direction；
Step E, after first guide rod (20) enters in soil layer, power head device (7) and first guide rod (20)
Second guide rod (20) is installed in separation additional, repeats step D, up to several guide rods (20) perforation active well (9) and connects
The soil layer between well (10) is received, guiding construction is completed；
The jacking pipe construction process includes the following steps:
Step F successively installs spoil disposal pipe die (26) and the first sludge pipe (25), carries out reaming jacking, while the first helix tube
(38) spiral jacking, so that soil is discharged from the first sludge pipe (25) rear portion；
Step G successively installs push pipe head (24) and three-in-one compound tube and is promoted；
Step H is laid with water service pipe (22) above three-in-one compound tube, and water service pipe (22) passes through water pipe (21) and slush pump (19)
Connection, water flowing play lubricating action to the perforation of push pipe；
Step I repeats step G and step H, until the soil layer between push pipe perforation active well (9) and received well (10)；
Step J successively dismantles spoil disposal pipe die (26), push pipe head (24) in received well (10), lifts recycling, so
After withdraw the second helix tube (27) and sludge pipe, push pipe is retained between active well (9) and received well (10) after successfully penetrating through
In soil layer.
8. a kind of construction technology using split type spiral push-bench according to claim 7, it is characterised in that: the step
The concrete operations of rapid B are as follows: power station (1) and mud pumping plant are placed in two sides respectively above active well (9), at active well (9) bottom
Host support frame back (11) are placed far from the side of received well (10) by portion, are sequentially placed master from the bottom to top in active well (9)
Machine support frame (35), adjustment base (6) and host (4) simultaneously carry out multi-direction fixation；
Then laser transit (2) are set up, so that the launching centre of laser transit (2) and the axis direction one to straight through tube
It causes, by oil pipe (13) connection power station (1) and oil cylinder (12), passes through water pipe (21) connection slush pump (19) and water filling device
(3), carry out test-run a machine is powered on after being installed.
