Product instruction manual

The auger boring machine is suitable for small pipe diameter Φ 300, Φ 400, Φ 500, Φ 600 (Φ 600 is only suitable for foreign pipelines), sewer pipeline,separate rain water pipeline and thermal pipeline casing, etc., steel and semi-steel pipeline laying. The equipment is small in volume and can be constructed in a circular working shaft with diameter 2500mm. The main performance characteristics of auger boring machine are as follows:

the equipment volume is small, the power is strong, the thrust is large, the jacking speed is fast, the requirement for operator skill is low, the horizontal straightness of the whole jacking process is ±30mm, can be shortened effectively and the construction cost and greatly improve work efficiency.
the construction area of foundation shaft is small, the road wide can be 3 meters, the minimum diameter of working shaft can be 2.5 meters, and the minimum diameter of receiving shaft can be 1.5 meters.
It has reduced cost of the environment pollution, good environmental , It does not produce the mud, the construction discharge is the wet mud or the dry soil, it has solved the city abandoned soil difficult problem, also may use the second time backfill;
Applicable to all kinds of normal soil such as soft soil, the clay, the sand soil, the gravel soil, the hard soil and the backfill.

The construction method of auger boring machine is three times construction method. The third construction method is divided into three times, the first construction is to push the guide bit and the guide drill pipe break through, the second construction uses the conduit pipe as the conductor, connecting the variable diameter pipe and 220 transition pipe to expand the diameter, after the diameter expansion is completed, the spiral pipe is pushed into the 220 transition pipe, and the third construction uses the submersible shield machine to expand the hole and push the pipe into the pipe.

For the first time, the guide bit is a bevel bit, and there is a target in the bit. The laser theodolite in the working shaft is used to observe the target, it can control the directio of the guiding bit. During the process of thrusting, because the stratum reaction force is opposite to the normal direction of the section, when there is no deviation in the thrusting direction of the guide bit, the guiding bit must keep rotating so that the stratum resistance acting on the cutting face can be offset and keep in a straight line. However, when there is a deviation during thrusting direction of the guide bit, then the direction of the section is adjusted to the appropriate orientation, the guide bit is stopped to be rotated make rectify the guide bit from the planned axle. When the guide bit is basically adjusted in place, it immediately starts to rotate the guide bit to maintain the straight direction and thrust the guide bit to the receiving shaft to complete the first construction.
In the second construction, the variable diameter pipe is installed on the guide rod, the push pad is installed on the head of the machine, one spiral casing is pushed in one after the other, and the matching spiral conveying pipe is loaded into the spiral casing after the 220 transition pipe is completely breakthrough, which is used for sand discharge,during subsequent excavation.
In the third construction, the auger boring machine (submersible shield machine) is connected behind the spiral conveyor pipe, the bore diameter(aperture) is extended to the size of the excavated thrusting (propulsion )pipe, and the cutting sand is discharged from the spiral conveying pipe to the receiving shaft. In order to reduce the friction force around the cutting head and the pipeline of the submersible shield machine, water or lubricating mud is often injected into the cutting head of the submersible shield machine, so that the soil is softened and easy to cutting, and the friction resistance of the push pipe can also be reduced. The detailed excavation steps are shown in the following figure:
