Solution instruction handbook

The auger unexciting device is suitable for modest pipe diameter Φ 300, Φ four hundred, Φ 500, Φ 600 (Φ 600 is only ideal for overseas pipelines), sewer pipeline,separate rain h2o pipeline and thermal pipeline casing, and so on., metal and semi-metal pipeline laying. The tools is tiny in volume and can be built in a round working shaft with diameter 2500mm. The main functionality traits of auger boring machine are as follows:

1. the tools volume is modest, the electrical power is robust, the thrust is massive, the jacking speed is fast, the prerequisite for operator talent is low, the horizontal straightness of the whole jacking procedure is ±30mm, can be shortened effectively and the development value and significantly boost function performance.
2. the development spot of basis shaft is tiny, the street broad can be 3 meters, the least diameter of functioning shaft can be 2.5 meters, and the minimal diameter of acquiring shaft can be 1.5 meters.
3. It has decreased price of the surroundings pollution, good environmental , It does not produce the mud, the building discharge is the damp mud or the dry soil, it has solved the metropolis abandoned soil challenging issue, also might use the next time backfill
4. Applicable to all sorts of regular soil such as delicate soil, the clay, the sand soil, the gravel soil, the tough soil and the backfill.

The building approach of auger boring machine is three instances construction method. The 3rd construction approach is divided into three instances, the initial development is to push the guide bit and the information drill pipe break by means of, the second design uses the conduit pipe as the conductor, connecting the variable diameter pipe and 220 transition pipe to grow the diameter, soon after the diameter enlargement is completed, the spiral pipe is pushed into the 220 changeover pipe, and the 3rd development utilizes the submersible shield device to increase the hole and press the pipe into the pipe.

1. For the 1st time, the guidebook little bit is a bevel little bit, and there is a target in the bit. The laser theodolite in the functioning shaft is utilized to observe the target, it can handle the directio of the guiding little bit. During the method of thrusting, since the stratum reaction power is reverse to the regular path of the section, when there is no deviation in the thrusting path of the guidebook bit, the guiding little bit have to keep rotating so that the stratum resistance performing on the slicing face can be offset and preserve in a straight line. However, when there is a deviation for the duration of thrusting direction of the manual little bit, then the course of the part is modified to the proper orientation, the guide little bit is stopped to be rotated make rectify the manual bit from the planned axle. When the manual bit is generally adjusted in place, it quickly begins to rotate the manual bit to sustain the straight route and thrust the manual little bit to the obtaining shaft to comprehensive the initial development.
2.  In the 2nd development, the variable diameter pipe is put in on the guide rod, the press pad is mounted on the head of the device, one spiral casing is pushed in a single following the other, and the matching spiral conveying pipe is loaded into the spiral casing after the 220 transition pipe is totally breakthrough, which is utilized for sand discharge,throughout subsequent excavation.
3. In the 3rd design, the auger uninteresting device (submersible shield machine) is connected powering the spiral conveyor pipe, the bore diameter(aperture) is extended to the measurement of the excavated thrusting (propulsion )pipe, and the cutting sand is discharged from the spiral conveying pipe to the getting shaft. In purchase to decrease the friction power around the chopping head and the pipeline of the submersible protect device, water or lubricating mud is typically injected into the chopping head of the submersible defend equipment, so that the soil is softened and straightforward to slicing, and the friction resistance of the press pipe can also be decreased. The detailed excavation measures are proven in the following figure:
