Groove excavation device for underground pipe network construction
Technical Field
The utility model relates to a trench excavation device technical field is used in construction of underground pipe network specifically is a trench excavation device is used in construction of underground pipe network.
Background
Before the pipeline groove is excavated, backfill prepressing is carried out corresponding to the designed pipe top elevation distance from the original ground under soil covering and the original foundation is loose so as to implement excavation construction and prevent pipeline joint breakage and pipeline displacement caused by road gene filling and rolling construction. If underground pipelines exist, after basic conditions of positions, depths, trends, pipes and connectors of various underground pipelines are checked before construction, early manual disclosure is adopted, the pipeline groove excavation adopts a 1 cubic meter backhoe excavator excavation and is manually matched, a certain pile is controlled and reserved through earthwork filling and excavation according to the principle of depth first and depth later, but the distance between the pile and the edge of the groove is larger than 2.0 meters, and if the underground pipelines meet the section with poor soil quality, the pile is strictly forbidden near the groove. And the excavator digs to a position 20cm away from the bottom of the tank and adopts manual soil digging, bottom cleaning and slope repairing.
Size design before the trench excavation and the address of beginning excavation are selected all theorically, generally only need to do planning in advance just not have a problem, but after beginning excavation, often can meet the unable fragmentation of great stone or other hard matters appearing in the soil the inside and continue to excavate, if excavate by force under the unknown condition, can passivate the outside flank of tooth of excavator, can make the outside flank of excavator like this for a long time more and more level, it is the cubic laminating until the surface that last excavator and ground contact present, can't get into earth and excavate, for this reason, we propose an underground pipe network construction and use excavation device.
