Farun Machinery Co., Ltd.

The ideal equipment for removing pipe-jacking rocks is the Fatrun hydraulic splitter
.
.

3. The process of using down-the-hole drilling and hydraulic splitter: .

3. 1. Working environment: trenchless pipe jacking, tunnel excavation
.


3. 2. Construction cases: Hunan For trenchless pipe jacking project, the pipe jacking diameter is about
meters and the excavation length is about
. In the trenchless pipe jacking project, silica with a hardness of
needs to be removed.
.


3. Construction conditions: It is prohibited to use
. Due to the diameter limit, large equipment cannot be used for construction. Hydraulic splitter or expansion agent can be used. cracking.
.


3. 4. Construction technology:
Equipment: one down-the-hole drill, one hydraulic splitter and one gun, auxiliary tools, shovel and crowbar.
.

3. Drilling large holes: A down-the-hole drill drills holes on the control surface of the jacking pipe. Take out the core and create a free surface of the rock
. />
3. Splitting: The down-the-hole drill drills to create a free surface, and the surrounding holes drilled by the core drill are used to split the silica with a splitter. The splitting of each hole only takes more than ten seconds.
.

3. Dismantling: After the splitting is completed, use crowbars to remove the rocks in time.
.


3. 5. Benefit Comparison The engineering company once used cement expansion agent, but due to severe water loss, it was difficult for the expansion agent to exert the effect of expansion and splitting, and the construction cost was high. , the effect is very unobvious and seriously affects the construction period. Secondly, the safety factor in the project of cement expansion agent cracking is low, which can easily cause safety accidents and cause

3. During the construction of the trenchless pipe jacking project, the silica was quickly removed after using the construction method of down-the-hole drill and hydraulic splitter. Every day The silica stone can be removed, and the excavation speed is increased by nearly ten times.
.

3. The hydraulic splitter is a good choice for trenchless pipe jacking construction. The rock concrete splitter also provides high operating efficiency for the project, saving costs and being convenient and fast.
