Small Water Drilling Pipe Jacking Machine

Small-sized top-driving machines are characterized by their small size, light weight, high efficiency, and ease of operation.
Water drilling jacking machine, also known as the water supply jacking machine, is a specialized jacking machine for hydropower engineering. Its characteristics are small and flexible, which has changed the working efficiency of the hydraulic jacking machine. The general soil jacking speed is 1 meter / 5 seconds, which is several times that of ordinary hydraulic jacking, and the jacking rod is made of high-strength water-injection type jacking rod. In the process of working progress, the residual soil is changed into mud by water injection, thereby reducing the friction force and also changing the resilience of the soil.nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp nbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbspnbsp

         The water drill jacking machine is equipped with an alloy drill bit in front, which does not deviate or slip when encountering solid objects, but it directly affects the progress speed. Please be sure to distinguish whether there are any other objects underground when using it. In general, the small jacking machine can adopt the direct jacking method for jacking without water when the diameter is small and the length is short, which greatly saves working time.
Water drilling jacking machine operation manual:
Check the water drilling and pipe jacking machine's wiring before use to ensure it is properly connected, free from leakage, or any cable scratches.
2. It is strictly prohibited to expand holes without water. It is necessary to adopt the method of first supplying water and then starting drilling, and first stopping drilling and then stopping the vehicle.
\ When expanding the hole, first use a 42 drill bit to drill through the pipe, and when retracting the rod, remove the drill bit and install the reaming tool to re-drill and expand the hole.
When drilling and expanding holes for the fourth time, it is necessary to adjust the speed of drilling and expanding holes based on the soil conditions and the size of the hole.
In order to facilitate construction, the small non-hydraulic pipe jacking machine is equipped with forward and reverse switches, solving the problem of manual operation being slow when changing the drill rod. (When changing the drill rod, it must be combined with the fixed clamp to lock the connection before changing the rod).
Observe carefully the changes in the work when changing the drill rod (especially when reversing the drill rod), and confirm that there is no looseness, slip, or disengagement of the drill rod.
\ When generally retracting and expanding the hole, the amount of water injection required is larger than that for normal straight drilling. Properly adjusting the flow rate of the high-pressure water pump can reduce the amount of sediment in the pipe.
Drilling with 8 holes, the water flow rate is generally 10～20L／min, and the pressure is 0.1～2MPa.
After the 9-hole expansion is completed, if the removal of pipe sediment is not satisfactory, the spiral rod provided with this machine can be used for a secondary excavation.
