Description
1. Construction covers a small area, can be constructed in narrow sites, greatly reduce the excavation ofthe road, less impact ontraffic.
2. using laser infrared level guidance, high accuracy, horizontal elevation error can be controlled within t 25mm. Meet therequirements of gravity flow drainage of sewage pipes.
3. No settlement on the ground, no impact on the surrounding environment and buildings, no gap between the pipe wall and thesoil layer after the pipeline is laid, there is no potential subsidence.
4. It is currently the fastest non-excavation sewage short pipe construction equipment of a construction process, simple operationeasy to learn and understand, greatly reducing construction costs.
5. jacking, pull back faster, suitable for a variety of geological, can be in the larger groundwater, quicksand belt construction.
6. lt is suitable for laying the sewage pipe (steel pipe, PE pipe, concrete pipe, FRp sandwich pipe, pvc thick-walled pipe, etc.) below800mm(including)inner diameter coin.
7. The clamping device can be moved back and forth, so that it is easy to unload and lit out the reamer after the pipe is towedback, without dismantling the clamping device, which is safe and efficient.
8. Can be customized according to customer requirements:
①Push-pull force: 650KN(65 tons)
②Torque:27000N.m
③Configuration of "rotary impact head" top drive head) for "short distance small diameter rock construction" lless than 50m).
Applications
The top-puling machine Pit-launched Directional Drill Rig is mainly used for non-excavation laving of sewage pipes, applicable to the operation in sewage wells witha diameter of 2.6 meters or more, and can also be used for other short-distance non-excavation pipe laying operations, mainly asfollows:
1. New sewage pipe: restricted by space (houses, rivers, etc.) can not swing the machine to build a sloping section.
2. Sewer pipe repair (original location for): direct well operation, to avoid the risk of creating a sloped section, to enhance thesuccess rate of pipe repair.
3. Urban electricity construction,renovation.
4. road crossing or embankment pipeline construction: affected by road trafic, or pipeline and pipe hole clearance requirementsare small, can not be placed or not allowed to use the horizontal directional drilling rig lot.
5. mud and water balance pipe jacking, spiral pipe jacking can not do the rock layer, quicksand strata.
